Description

Waterproof ring mould

Technical Field

The utility model relates to a waterproof ring mold.

Background

A conventional injection mold generally includes an upper mold plate, a lower mold plate, and a cavity module disposed between the upper mold plate and the lower mold plate, where the cavity module includes a cavity male mold and a cavity female mold.

Detailed Description

Referring to fig. 1-5, the waterproof ring mold comprises an upper mold plate 1 and a lower mold plate 2, wherein an upper cavity convex core 3 is arranged in the upper mold plate 1, a lower cavity convex core 4 is arranged in the lower mold plate 2, and a middle mold plate 5 is arranged between the upper mold plate 1 and the lower mold plate 2. A hollow middle groove 6 is arranged in the middle template 5. After the upper template 1, the lower template 2 and the middle template 5 are assembled, the lower cavity convex core 4 of the lower template 2 extends out of the middle groove 6 and forms a groove together with the edge of the middle groove 6, and finally, a gap (namely all grooves) among the upper cavity convex core 3, the middle groove 6 and the lower cavity convex core 4 forms a cavity 7 of a waterproof ring together. And (3) injecting liquid rubber or silica gel into the cavity 7, and cooling to obtain the rubber or silica gel waterproof ring.

Preferably, an upper profiled groove 8 is arranged in the upper cavity convex core 3 of the upper template 1, a lower profiled groove 9 is arranged in the lower cavity convex core 4 of the lower template 2, and the cavity 7 is composed of the upper profiled groove 8, the middle profiled groove 6 and the lower profiled groove 9. After the upper template 1, the lower template 2 and the middle template 5 are assembled, the edges of the upper cavity convex core 3, the middle groove 6 and the lower cavity convex core 4 are overlapped, and the edge of the waterproof ring which is injected by the structure has no waste edge and does not need to be trimmed, so that the quality and the efficiency can be improved.
