The present invention relates to the field of mould, and in particular, to the design and manufacturing of a mould.
Generally, a product having a catch may be moulded by means of a taper pin. For example, as shown in
However, as shown in
An objective of this disclosure is to provide a mould for moulding a product having a complicated configuration and having a catch.
In order to solve the technical problems as set forth above, the mould provided by the disclosure includes a female mould and a male mould, the female mould including a cavity insert and the male mould including a core insert. The mould further includes a guiding block and a sliding block, and the core insert is formed therein with a receiving chamber for retaining the sliding block; the sliding block is able to be moved along a parting surface of the female mould; a first end of the sliding block is able to be connected to the male mould through a resilient member; a first recess is formed on a side of the sliding block facing the cavity insert; the guiding block is provided in the cavity insert and protruded towards the male mould; a portion of the guiding block exceeding the cavity insert is able to be inserted into the first recess, such that the resilient member is compressed; the sliding block is formed thereon with a moulding surface; and, the moulding surface of the sliding block together with a moulding surface of the core insert and a moulding surface of the cavity insert collectively form a moulding cavity.
Optionally, a second end of the sliding block has a protrusion facing the cavity insert; the moulding surface of the sliding block is formed on a lower surface of the protrusion, and a catch groove is provided on the moulding surface of the sliding block; when the male mould and the female mould are assembled, a clearance is formed between an upper surface of the second end of the sliding block and the core insert; and, a maximum height of the clearance in the moving direction of the sliding block is greater than a depth of the catch groove.
Optionally, the male mould further includes a male mould plate; the resilient member is fixedly connected to the male mould plate at one end and fixedly connected to the sliding block at the other end.
Optionally, the male mould plate is provided with a second recess in which the resilient member is retained.
Optionally, a portion of the guiding block is fixed to the cavity insert in an inserted manner.
Optionally, the portion of the guiding block exceeding the cavity insert has an upwards inclined lower surface; when the male mould and the female mould are assembled, a lower surface of the first recess is brought into contact with a lower surface of the portion of the guiding block exceeding the cavity insert.
In the mould provided by the disclosure, the sliding block and the guiding block can cooperate with each other, such that the mould is able to mould a product having a curved configuration and having a catch, whereby solving a problem that it is difficult for the existing mould to mould a product having a complicated configuration.
Accompanying drawings are provided for further understanding of this disclosure and constituting a part of the specification. Hereinafter, these drawings are intended to explain the disclosure together with the following specific embodiments, but should not be considered as a limitation of the disclosure.
In reference numerals, 1, 100-a cavity insert; 2, 200-a core insert; 3-a taper pin; 31, 303-a catch groove; 4, 400-a product; 41, 401-a catch; 42-a portion exceeding the taper pin; 110-a guiding block; 111-a lower surface of a portion of the guiding block exceeding the cavity insert; 300-a sliding block; 301-a first recess; 3011-a lower surface of the first recess; 304-a protrusion; 500-a female mould plate; 600-a male mould plate; 601-a second recess; 700-a resilient member; 800-a clearance.
Hereinafter, specific embodiments of the disclosure will be described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments as set forth herein are merely for the purpose of illustration and explanation of the disclosure and should not be constructed as a limitation thereof.
A mould according to the disclosure may include a female mould and a male mould.
The female mould includes a cavity insert 100, and the male mould includes a core insert 200. The mould may further include a guiding block 110 and a sliding block 300. The core insert 200 is formed therein with a receiving chamber for retaining the sliding block 300. The sliding block 300 can be moved along a parting surface of the female mould. A first end of the sliding block 300 can be connected to the male mould through a resilient member 700. In this embodiment, the resilient member 700 may be a spring.
As shown in
The sliding block 300 is formed thereon with a moulding surface. As shown in
Referring to
Further, a protrusion 304 facing the cavity insert 100 is formed at a second end (an end which is not in connection with the resilient member 700) of the sliding block 300. The moulding surface of the sliding block is formed on a lower surface of the protrusion 304, and as shown in
Compared with the prior art, in the mould provided according to this disclosure, the sliding block 300 can be used cooperatively with the guiding block 110, such that the mould of the disclosure is able to mould a product (such as, the product 400) having a complicated configuration such as a curved surface and having a catch, whereby solving a problem that it is difficult for the existing mould to design a catch for a product having a complicated configuration.
Optionally, the female mould may further include a female mould plate 500, and the male mould may further include a male mould plate 600.
In this disclosure, the position of the resilient member 700 is not specifically restricted, as long as the resilient member 700 can apply a resilient force to the sliding block 300. For example, the receiving chamber of the core insert 200 may be a recess with three closed sides (at least the bottom side thereof is closed) and one open side in its cross section, and the resilient member 700 is provided on the bottom side of the receiving chamber; or, the receiving chamber has two open sides in its cross section (as shown in
In this disclosure, the guiding block 110 is fixed to the cavity insert 100. For example, a portion of the guiding block 110 may be fixed to the cavity insert 100 in an inserted manner. Alternatively, the guiding block 110 may be formed integrally with the cavity insert 100. However, the guiding block 110 is preferably inserted into the cavity insert 100, so that the cavity insert 100 and the guiding block 110 may be processed individually to decrease complexity in process. As shown in
Operational modes of the mould provided by the disclosure will be described hereinafter.
In the prior art, it is difficult to mould a complicated product having a curved surface and having a catch by means of the taper pin. According to this disclosure, however, the catch of the product can be easily released from the catch groove 303 by the cooperation of the sliding block 300 with the guiding block 110.
In addition, the lower surface of the protrusion 304 of the sliding block 300 is used as the moulding surface of the sliding block, on which the catch groove 303 is provided. Therefore, the curved configuration of the product having the catch can be changed simply by adjusting the shape of the moulding surface of the sliding block, so that the problem that it is difficult for the existing mould to mould a product having a complicated configuration is solved.
It should be understood that the above implementations are merely exemplary embodiments for the purpose of illustrating the principle of the disclosure, and the disclosure is not limited thereto. Various modifications and improvements can be made by a person having ordinary skill in the art without departing from the spirit and essence of the disclosure. Accordingly, all of the modifications and improvements also fall into the protection scope of the disclosure.
