Straight ejector and inclined ejector combining structure for injection mould

Abstract

The invention relates to a straight ejector and inclined ejector combining structure for an injection mould. The straight ejector and inclined ejector combining structure is characterized by comprising a straight ejector part, an inclined ejector part matched with the straight ejector part, and an elastic mould opening auxiliary structure. The straight ejector part comprises a straight ejector block, a guide rail and ejector rods. The guide rail is arranged at the lower end of the straight ejector block. The ejector rods are arranged at the lower end of the guide rail. A first mould opening surface is arranged on one side of the straight ejector block. A first spacing hole penetrating through the first mould opening surface is formed in the straight ejector block. The inclined ejector part comprises an inclined ejector block and an inclined guide rod. The inclined guide rod is fixed at the lower end of the inclined ejector block. The inclined ejector block is provided with a second mould opening surface matched with the first mould opening surface. A second spacing hole penetrating through the second mould opening surface is formed in the inclined ejector block. A guiding groove matched with the guide rail is formed in the inclined ejector block. The inclined guide rod extends downwards obliquely in a direction close to the straight ejector block. The mould opening auxiliary structure comprises a spring part. One end of the spring part is sleeved by the first spacing hole. The other end of the spring part is sleeved by the second spacing hole. The straight ejector and inclined ejector combining structure is simple, and high in stability, and can meet the production requirement of complex products.

Description

technical field [0001] The invention relates to a joint structure of straight roof and inclined roof of injection mold. Background technique [0002] People's requirements for the appearance of automobiles are constantly increasing. As a part of the appearance of automobiles, bumpers also increase the manufacturing requirements for bumper products. The structure of bumper products is becoming more and more complicated, and the manufacturing difficulty is increasing. To achieve mold release, the product must be modified or sacrificed at the expense of mold strength to ensure smooth product release, resulting in large wear and tear of injection molds, low production efficiency, and increased production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a combined structure of straight top and inclined top of the injection mold, which is small in size, simple in structure, good in stabi...
