Automobile glass edge covering die adopting elastic positioning points to position glass

Abstract

The invention relates to an automobile glass edge covering die adopting elastic positioning points to position glass. The die comprises an upper die and a lower die which are matched, wherein the lower die is used for placing glass, the upper die is used for being combined with the lower die for edge covering of the glass, a positioning groove is formed in the lower die, a positioning block and aspring are arranged in the positioning groove, the lower end of the spring abuts against the bottom of the positioning groove, the upper end of the spring abuts against the bottom of the positioning block, the positioning block is used for positioning the glass, when the upper die and the lower die are separated, the spring is in a natural extension state, the positioning block is bounced up by the spring and extends out of the positioning groove to position the glass, when the upper die and the lower die are closed, the upper die presses down to press the positioning block back into the positioning groove, the spring is compressed, and the spring automatically bounces up when the die is opened. Compared with the prior art, the automobile glass edge covering die adopting the elastic positioning points to position the glass is simple in structure and accurate in positioning.

Description

technical field [0001] The invention relates to an automobile edge-wrapping mold, in particular to an automobile glass edge-wrapping mold which adopts elastic positioning points for glass positioning. Background technique [0002] TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material with high strength, high resilience, and can be processed by injection molding. It has a wide range of applications, is environmentally friendly, non-toxic and safe, and has excellent colorability. [0003] TPE is often used to make the edge of the rear windshield of the car. At present, automotive glass injection molding products are made by coating the glass plate with a primer, and then putting the metal reinforcement, plastic inserts and glass into the mold, passing the TPE material into the mold for injection molding, and cooling, so as to make the overall injection molding product. [0004] Chinese patent CN206870264U has introduced a kind of mold structure that is used for...

Problems solved by technology

[0007] However, the above-mentioned method of positioning through the cylinder has the disadvantage that the positioning accuracy can be guaranteed only when the positioning cylinder moves repeatedly.

During production, other factors may easily cause the control switch to fail and cause damage to the cylinder, so spare parts need to be purchased

And because different product structures are different, each mold requires a different cylinder stroke, so it is necessary to back up a variety of cylinder spare parts. On the one hand, it causes inventory waste. the problem of taking up space
