Problems solved by technology

[0002] Automobile rear lamp housings are all made of injection molds. According to the existing technology, there are two characteristic positions on the lower surface of automobile rear lamp housing products that are not suitable for ejection mechanisms. If an oil cylinder is used as a core puller, the cost will increase and the oil cylinder Placement and re-testing are prone to the risk of oil leakage into the mold, and will increase the size of the mold

Abstract

The invention discloses an injection mold for an automobile back light shell body. The injection mold comprises an upper template, a lower template and a mold leg which fixed below the lower template,wherein the upper template is located on the upper surface of the lower template; a push plate is arranged between the mold leg and the lower template; the push plate is arranged in the mold leg in asliding match manner; a mold cavity for molding a product is arranged between the upper surface of the lower template and the lower surface of the upper template; a first opening groove and a secondopening groove are formed in the lower surface of the product respectively; the first opening groove is located above the second opening groove; a first included angle is formed between the central line of the first opening groove and a vertical plane; a second included angle is formed between the central line of the second opening groove and the vertical plane. The injection mold provided by theinvention has the advantages that the cost is low, oil does not seep into the mold and the size of the mold is not increased.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold used for automobile rear lamp housings. Background technique [0002] Automobile rear lamp housings are all made of injection molds. According to the existing technology, there are two characteristic positions on the lower surface of automobile rear lamp housing products that are not suitable for ejection mechanisms. If an oil cylinder is used for core pulling, the cost will increase and the oil cylinder Placement and re-testing are prone to the risk of oil leakage into the mold and will increase the size of the mold. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art and provide an injection mold with low cost, no oil seeping into the mold and no increase in mold size. [0004] The technical solution adopted by the present invention is: an injection mold for automobil...
