Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the feeding mechanism of the plastic product injection mold with the class-a appearance surface is provided with a glue inlet channel communicated with a molding cavity of the injection mold, a glue inlet k1 for feeding glue into the molding cavity from the glue inlet channel is positioned at one side of the molding cavity, and after the plastic product 100 is subjected to injection molding, the glue inlet k1 can slide away from the plastic product 100.
Specifically, feed mechanism includes briquetting 4 and slider 1, and briquetting 4 is located on the injection mould cover half, and slider 1 is gliding to be located on the injection mould movable mould, advances the gluey passageway and forms between briquetting 4 and slider 1, advances gluey mouth k1 and locates on slider 1. The glue inlet channel comprises a glue inlet groove 11 arranged on the sliding block 1 and a glue inlet hole 12 arranged on the pressing block 4.
When glue is injected, the movable mold and the fixed mold are mutually assembled, the glue enters the glue inlet groove 11 from the glue inlet hole 12 and finally enters the molding cavity of the mold from the glue inlet k1, after the product is injected, the movable mold moves and is separated from the fixed mold, the sliding block 1 slides to one side under the action of mold opening power (the sliding block 1 is provided with an inclined guide hole and an inclined guide rod), so that the pouring gate 101 is torn away from the product, the pouring gate 101 is torn away from the product due to the small opening of the glue inlet k1, the product cannot be damaged, the joint of the pouring gate 101 and the product is positioned on the side edge of the product, and the joint is not positioned on the A-level appearance surface, and the appearance requirement of the A-level appearance surface is effectively met.
Further, the glue feeding mechanism further comprises a removing mechanism for removing the gate 101 generated in the glue feeding channel. The removing mechanism comprises a glue blocking rod 21, and the glue blocking rod 21 can eject the gate 101 out of the glue inlet groove 11.
