Description

Dustproof device

The invention relates to a dustproof device, in particular to a dustproof device capable of keeping a mold core away from a pollution source such as dust to maintain the mold core.

With the development of technology, injection molding technology has gradually entered the field of optics with its excellent characteristics. The injection mold used in injection molding mainly includes a mold base and a mold core mounted on the mold base. For the manufacturing method of the mold core, please refer to the paper published by Tseng et al., 1990 IEEE International Symposium on Intelligent Control, Knowledge-based mold design for injection molding processing.

As shown in FIG. 1 , a commonly used mold core 10 includes an upper mold core 101 and a lower mold core 102. The upper mold core 101 and the lower mold core 102 are respectively provided with a plurality of matching molding surfaces 100 for respectively forming the lens. The upper surface and the lower surface form a complete lens.

When the injection mold is being repaired or repaired, the components, such as the upper mold core 101 and the lower mold core 102, are removed and placed on the work table for assembling the mold, since the upper mold core 101 and the lower mold core 102 are The plurality of molding faces 100 are directly used for molding lenses, and the precision thereof is relatively high. Therefore, when the upper die 101 and the lower die 102 are placed on a table, the molding surface 100 should be placed upward to avoid contact with the table. And wear occurs, but when the molding surface 100 is disposed upward, it is likely to be contaminated with dust or other contaminating particles in the air, thereby causing the surface of the lens during the molding process to be contaminated with the dust or other contaminating particles, and The final molded lens is scrapped.

In view of the above, it is necessary to provide a dustproof device that can protect the mold core from a source of pollution such as dust to maintain the mold core.

Hereinafter, a dustproof device will be described by way of example, which can keep the mold core away from a source of pollution such as dust to maintain the mold core.

A dustproof device for accommodating a mold core and keeping the mold core away from a source of pollution such as dust to maintain the mold core, comprising: a hollow casing, the hollow casing including an upper surface, a lower surface, and a connection a receiving space for receiving the mold core is formed on the side surface of the upper surface and the lower surface. The side surface defines an opening and two linear sliding rails. The receiving space communicates with the outside through the opening. The linear slides are disposed parallel to each other on the hollow housing; a sliding plate is slidable along the linear slide to close the opening.

Compared with the prior art, the dustproof device can be accommodated in the hollow by providing a hollow casing having a receiving space to receive the mold core and closing the opening by providing a sliding plate that can slide along the linear sliding rail.
