Problems solved by technology

[0002] For a pair of auto parts, the surface to be demoulded includes the large side area 01 and the side hole 02. The demoulding direction of the large side area 01 is inconsistent with the angle of the side hole 02 and has a large difference. Secondly, the side hole 02 is 18mm deep. In the prior art, separate core-pulling mechanisms are usually used to demould the large side area 01 and the side hole 02, but due to space problems, two sets of core-pulling mechanisms cannot exist at the same time, and the cost of the two sets of core-pulling mechanisms is also high

Abstract

The invention provides an ejecting mechanism for a side inclined hole. The effect of demolding a large-side area and the side hole by one core pulling mechanism respectively is realized. A moving mold(1) is provided with an oil cylinder (5); the oil cylinder (5) is provided with a pushing rod (6); a pushing block (8) is in threaded connection with the pushing rod (6); a large sliding block (4) isconnected with the pushing block (8); an insert (9) is provided with a slide (10); an elastic pin (11) is glidingly arranged inside the slide (10); a profile fit with the side hole (02) is arranged at one end of the elastic pin (11); a base (12) is fixedly arranged at the other end; a large sliding block (4) is provided with a pipeline (13); the elastic pin (11) is sleeved with a spring (14); thespring (14) is located in the pipeline (13); and the elastic pin (11) comprises an ejecting pin (22), an ejecting pin base (23) and an ejecting pin fixing pipe.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an ejection mechanism for side inclined holes. Background technique [0002] For a pair of auto parts, the surface to be demoulded includes the large side area 01 and the side hole 02. The demoulding direction of the large side area 01 is inconsistent with the angle of the side hole 02 and has a large difference. Secondly, the side hole 02 is 18mm deep. In the prior art, the large side area 01 and the side hole 02 are usually demoulded by separately setting core-pulling mechanisms, but due to space problems, two sets of core-pulling mechanisms cannot exist at the same time, and the cost of the two sets of core-pulling mechanisms is also high. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the prior art, the present invention provides an ejection mechanism for side oblique holes, which realizes the effect of one core-pullin...
