Processing mold for cellulose acetate plastic sheet glasses

Abstract

The invention discloses a processing mold for cellulose acetate plastic sheet glasses. The processing mold comprises a base, an ejection mechanism, a support rod and an ejection piece, wherein a lowermold is arranged on the right side of the base, the lower mold is connected to the outside of the base in a welding mode, the right side of the lower mold is fixedly connected with an upper mold, a cavity is formed inside the lower mold, an ejection mechanism is mounted inside the cavity, and a push plate is arranged on the right side of the ejection mechanism. According to the processing mold for the cellulose acetate plastic sheet glasses, the ejection piece with the same size as a plastic sheet workpiece is arranged outside the ejection mechanism, and when the workpiece is ejected out, theejection piece can be attached to the bottom of the workpiece with a maximum area, so that the problem of uneven stress caused by small contact area with the workpiece when the workpiece is ejected out by a traditional ejection rod is solved; and after the plastic sheet workpiece is processed well, the circular-ring-shaped ejection piece can cover the bottom of the workpiece well and push the workpiece in combination with the push rod, so that the workpiece is stripped intact, the stripping yield is high, the overall structure is simple, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of glasses rubber sheet processing, in particular to a processing mold for glasses rubber sheets. Background technique [0002] Spectacle rubber sheet is a workpiece such as a mirror frame made of acetate fiberglass sheet. It is characterized by a certain degree of elasticity. When it is slightly bent or stretched and then relaxed, the shape memory sheet will return to its original shape. According to different manufacturing processes, it can be Divided into plate frame, injection frame. [0003] Most of the glasses rubber sheet processing molds on the market use the ejector rod to push the workpiece out of the mold cavity after the workpiece is processed to complete the demoulding work. However, because the material of the glasses rubber sheet itself is relatively brittle, the ejector rod and the The contact area of ​​the workpiece is small, and it is easy to cause uneven force on the workpiece during ejec...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a processing mold for glasses rubber sheet, which solves the problem that most of the existing glasses rubber sheet processing molds on the market use ejector rods to push the workpiece out of the mold cavity after the workpiece is processed. In this way, the demoulding work is completed, and because the material of the glasses rubber plate itself is relatively brittle, and the contact area between the ejector rod and the workpiece is small, it is easy to cause uneven force on the workpiece during ejection and damage the workpiece, which is troublesome to use The problem
