specific Embodiment

[0024] Three small top blocks II15 are arranged on one side edge of the transparent small cover 1, and three large top blocks I3 are arranged on one side edge of the transparent large cover 2. The mold cavity 4 is fixed in the movable template 6; the other side of the small transparent cover 1 is connected with the large transparent cover 2 through a designed flow channel, and an auxiliary flow channel is designed at one end of the two parts for ejection balance. In this way, the auxiliary ejector pin I12 and the auxiliary ejector pin II13 can be arranged under the runner and the auxiliary runner without needing to stand on the product parts; the ejector pin 5, the auxiliary ejector pin I12 and the auxiliary ejector pin II13 are all fixed on the top plate 7 , The connection of the supporting plate 8, the top plate 7, the movable mold base plate 9 and the mold foot 11 all meet the requirements of the standard mold base of Long Kee, and the top stick 10 is configured on the injec...

Abstract

The invention discloses a circuit breaker transparent cover injection mold ejection mechanism. The ejection mechanism comprises an ejection plate, ejection rods, a support plate and an ejection roller which are arranged in an injection mold, the support plate is arranged on the ejection roller, the ejection plate is arranged on the support plate, one end of each ejection rod is fixed to the ejection plate, and the other end of each ejection rod is provided with an ejection block used for ejecting a transparent cover. The ejection blocks are designed corresponding to the edge of the transparent cover of a circuit breaker, the transparent cover is ejected through the ejection blocks, and obvious traces are not left after the transparent cover is ejected out; ejection pins are designed corresponding to auxiliary runners, the transparent cover can be smoothly brought out, ejection traces are not left on the cover, the ejection quality of the transparent cover is improved, and the appearance of the transparent cover of the circuit breaker meets the requirement.

Description

technical field [0001] The invention relates to the technical field of circuit breaker manufacturing, in particular to an ejection mechanism of an injection mold for a transparent cover of a circuit breaker. Background technique [0002] For the injection molding process of transparent appearance parts, in addition to the surface quality of the molding process, the ejection method also needs to be considered. Because it is a transparent cover, if the thimble is designed on the inner surface, it will be ejected directly through the thimble, which will affect the appearance of the product. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an ejection mechanism for the injection mold of the transparent cover of the circuit breaker, so as to achieve the purpose of improving the ejection quality of the transparent cover. [0004] In order to solve the problems of the technol...
