A synchronous and counter-directional double core-pulling slider mechanism

Abstract

The invention provides a synchronous and different directional double core pulling sliding block mechanism, which comprises a pressing block pull rod screw, double trapezoid pressing blocks, an outer pulling sliding block body, an outer pulling sliding block body pull rod screw, a limiting plate, an outer pulling sliding block body spring, an inner pulling sliding block body pull rod screw, a limiting plate screw, an inner pulling sliding block body spring and an inner pulling sliding block body. The core pulling sliding block mechanism can perform inner and outer core pulling synchronously at the same time; by adopting the mechanism, inner and outer core pulling needing to be performed on the same wall surfaces of products are integrated into synchronous core pulling performed by one core pulling mechanism, so that the design layout space of a mold is saved, the mold design size is reduced and the mold production and manufacturing cost is lowered; the core pulling sliding block mechanism is reasonable in structure design, compact in structure, stable in work and convenient to use and is safe and reliable.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a synchronous and different-direction double core-pulling slider mechanism. Background technique [0002] When the product has outer core-pulling holes and inner core-pulling blind holes with different upper and lower positions on the same wall, the outer core-pulling hole can be pulled out with a slider core, but the design position of the inner inner core-pulling blind hole is inclined. The layout will be difficult to arrange. If the same core-pulling mechanism can be used to realize synchronous core-pulling of the inner and outer holes, it will save design space and reduce the difficulty of mold design and mold processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a synchronous and counter-directional double core-pulling slider mechanism, which is reasonable in design, compact in structure, stab...

[0002] When the product has outer core-pulling holes and inner core-pulling blind holes with different upper and lower positions on the same wall, the outer core-pulling hole can be pulled out with a slider core, but the design position of the inner inner core-pulling blind hole is inclined. The layout will not be easy to arrange. If the same core-pulling mechanism can be used to achieve synchronous core-pulling of the inner and outer holes, it will save design space and reduce the difficulty of mold design and mold processing.
