8821146
1. Technical Field
The present disclosure relates to molds, and more particularly to a mold for manufacturing input/output (I/O) ports of a computer front panel.
2. Description of Related Art
In a computer, a front panel is attached on a front side of an enclosure of the computer to cover the front side. For conveniently connecting to peripheral devices, input/output (I/O) ports are formed on the front side. However, for different computers, the I/O ports are different. Therefore, different molds may be needed to manufacture different front panels which have different I/O ports.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
Referring to
The mold core 30 includes a bottom wall 31, a pair of parallel first sidewalls 33, and a pair of parallel second sidewalls 35. The pair of first sidewalls 33 are connected to two opposite edges of the bottom wall 31. The pair of second sidewalls 35 are connected to another two opposite edges of the bottom wall 31. The pair of second sidewalls 35 are perpendicular to the pair of first sidewalls 33. The bottom wall 31, the pair of first sidewalls 33, and the pair of second sidewalls 35 cooperatively define a cavity 60.
Each of the pair of first sidewalls 33 defines a hole 334. An elastic piece 331 is connected to opposite edges of the hole 334. The elastic pieces 331 of the pair of sidewalls 33 extend toward each other. Each of the elastic pieces 331 includes a pair of connection portions 3311 and an abutting portion 3313. Each of the pair of connection portions 3311 are slantingly connected to a corresponding one of the pair of first sidewalls 33. A gap 332 is defined between the abutting portion 3313 and the first sidewall 33. The two elastic pieces 331 of the pair of first sidewalls 33 divides the cavity 60 into a first room 61 and a second room 63.
Referring to
To form the first I/O port assembly 10, the first cover panel 41 of the first cover 40 is placed on the cavity 60 of the mold core 30. The clasp 421 of the first cover panel 41 is inserted in the gap 332 and engaged on the elastic piece 331 to mount the first cover 40 on the mold core 30. Liquid plastic material is injected in the first room 61 of the cavity 60 via the first plug holes 411. The liquid plastic material is solidified in the first room 61 to form the first I/O port assembly 10.
Referring to
To form the second I/O port assembly 20, the second cover panel 51 of the second cover 50 is covered on the cavity 60 of the mold core 30. The pair of second side panels 53 is located between the pair of first sidewalls 33 of the mold core 30. The abutting portions 3313 of the elastic pieces 331 abut the pair of second side panels 53 and are deformed by the pair of second side panels 53. The elastic pieces 331 urge on the pair of second side panels 53 to mount the second cover 50 on the mold core 30. Liquid plastic material is injected in the first room 61 and the second room 63 of the cavity 60 via the second plug holes 511. The liquid plastic material is solidified in the first room 61 and the second room 63 to form the second I/O port assembly 20.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
