In an embodiment of the present invention, the method of using the mold further includes: finely adjusting an inner contour of the first mold core, wherein the first mold core further includes a second shaping element, a contour of a second shaping surface of the second shaping element is different from a contour of the first shaping surface of the first shaping element, and the second shaping element is selectively arranged in the hole instead of the first shaping element to change a local contour of the first mold cavity or the second mold cavity.
In an embodiment of the present invention, the filling component is a single filling element in contact with both of the first mold core and the second mold core, or, the filling component includes a first filling element and a second filling element, the second filling element corresponds to the first filling element, and corresponding positions in the first mold core and the second mold core are filled with the first filling element and the second filling element respectively.
In an embodiment of the present invention, the first mold cavity and the second mold cavity are different in at least one of width and length.
Based on the foregoing, the filling component of the mold of the embodiment of the present invention is detachably arranged in the local region in the first mold cavity and therefore the first using mode or the second using mode may be selectively executed to manufacture the first molding element or second molding element in different shapes or sizes. In such a manner, different molding elements in different shapes or sizes may be produced without multiple sets of molds, and the cost of manufacturing other sets of molds may be saved.
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with the accompanying drawings are described in detail below.
Referring to
In the present embodiment, the first mold core 110 may have a first bottom surface 110a and a first joint surface 110b, and the second mold core 120 may have a second bottom surface 120a and a second joint surface 120b. The first bottom surface 110a of the first mold core 110 and the second bottom surface 120a of the second mold core 120 correspond to upper and lower surfaces of the first molding element respectively. When the second mold core 120 is arranged at the first mold core 110, the first joint surface 110b is adapted to be jointed to the second joint surface 120b.
In a first using mode, as shown in
In a second using mode, as shown in
Therefore, the mold 100 of the present embodiment is adapted to manufacture the first molding element in the first using mode and adapted to manufacture the second molding element in the second using mode. Then, the first using mode or the second using mode may be selectively executed to manufacture the two molding elements in different shapes or sizes by use of the mold 100 of the present invention without using two sets of molds, so that the cost of manufacturing another set of mold may be saved.
In addition, the mold 100 of the present embodiment may further include a first mold base 140 and second mold base 150 which are bases of the first mold core 110 and the second mold core 120 respectively. The first mold core 110 is adapted to be arranged at the first mold base 140 and the second mold core 120 is adapted to be arranged at the second mold base 150.
In the present embodiment, the first mold cavity C1 and the second mold cavity C2 are different in at least one of width and length. Specifically, the first mold cavity C1 has a first width W1 and a first length L1, and the second mold cavity C2 has a second width W2 and a second length L2, wherein the first width W1 is different from the second width W2, and the first length L1 is the same as the second length L2. However, in another embodiment, the first width W1 may be the same as the second width W2, and the first length L1 may be different from the second length L2. Alternatively, the first width W1 may be different from the second width W2, and the first length L1 may also be different from the second length L2.
In addition, the first mold core 110 includes a main body 112 and a first shaping element 114, the main body 112 has a hole 112a. The hole 112a may be selectively filled with the first shaping element 114, and when the first shaping element 114 is arranged in the hole 112a, the first shaping element 114 has a first shaping surface 114a exposed from the hole 112a. In another embodiment, the second mold core 120 may include a main body and a first shaping element, or each of the first mold core 110 and the second mold core 120 includes a main body and a first shaping element. The present invention is not limited thereto. Herein, a contour of the first shaping surface 114a in
Specifically, according to the mold 100 of the present invention, the filling component 130 is arranged in the first mold cavity C1 to produce the second molding element different from the first molding element, and the inner contour of the first mold core 110 is finely modified by use of different shaping elements. Therefore, except the local region where the filling component 130 is arranged, the first molding element and the second molding element have similar contours. That is, the mold 100 of the embodiment of the present invention is adapted to produce various molding elements with the same or similar local contours.
Based on the foregoing, according to the mold 100 of the present embodiment, the contour of the mold cavity formed in the mold 100 is changed in two manners. In the first manner, the first mold cavity C1 is filled with the filling component 130 to form the second mold cavity C2. In the second manner, the second shaping element 116 replaces the first shaping element 114 arranged in the hole 112a to change the local contour of the first mold cavity C1 or the second mold cavity C2. In the two manners, the contour of the mold cavity formed in the mold 100 may be changed. Therefore, according to the mold 100 of the present embodiment, multiple molding elements in different shapes or sizes may be manufactured by use of a single set of mold, and the mold manufacturing cost may be saved.
Herein, a region R1 of the first molding element 10a is equivalent to the position of the filling component 130 in
Based on the foregoing, the filling component of the mold of the embodiment of the present invention is detachably arranged in the local region in the first mold cavity, and therefore the first using mode or the second using mode may be selectively executed to manufacture the first molding element or the second molding element in different shapes or sizes. In such a manner, different molding elements in different shapes or sizes may be produced without multiple sets of molds, and the cost of manufacturing molds may be saved.
Although the embodiments of the present invention have been disclosed as above, they are not intended to limit the present invention. Those of ordinary skill in the art may make some modifications and embellishments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be subject to the appended claims.
