Oblique core-pulling mechanism of injection mold

Abstract

The invention discloses an oblique core-pulling mechanism of an injection mold. The oblique core-pulling mechanism comprises an upper mold plate and a lower mold plate which can be opened and closed with the upper mold plate, wherein an upper mold insert is arranged on the upper mold plate, a lower mold insert is arranged on the lower mold plate, a sliding block which can slide left and right relative to the upper mold plate and the lower mold plate is arranged between the upper mold plate and the lower mold plate, an oblique slot which is oblique is arranged on the lower mold insert, a moving mold core which can move along with the sliding block and form a plastic part molding cavity with the lower mold insert and the upper mold insert by enclosing is arranged in the oblique slot, and a wedging block which can wedge the sliding block when the wedging block is closed with the lower mold plate is arranged on the upper mold plate. According to the oblique core-pulling mechanism disclosed by the invention, in the mold opening process of the upper mold plate and the lower mold plate, the moving mold core can move together with the sliding block so as to complete oblique core pulling and avoid the defect that a traditional core-pulling mechanism needs hydraulic or pneumatic drive. The oblique core-pulling mechanism disclosed by the invention has the advantages of simple and compact structure, convenience in operation and low cost, and can reduce the requirements on injection molding production conditions.

Description

【Technical field】 [0001] The invention relates to a side core-pulling mechanism of an injection mold, in particular to an oblique core-pulling mechanism of an injection mold. 【Background technique】 [0002] At present, plastic products are widely used in daily life, and the side core pulling mechanism is also a common mechanism in injection molds. For inclined holes on plastic parts, traditional injection molds generally use hydraulic or pneumatic core-pulling mechanisms to achieve demoulding and core-pulling, but the use of such core-pulling structures leads to large injection mold structures and increased equipment costs The production conditions for injection molding are very demanding. [0003] Therefore, the present invention is made based on the above circumstances. 【Content of invention】 [0004] The object of the present invention is to overcome the disadvantages of the prior art, and provide an oblique core-pulling mechanism for injection molds with simple and c...
