Synchronous different-direction-type double core pulling sliding block mechanism and using method thereof

Abstract

The invention provides a synchronous different-direction-type double core pulling sliding block mechanism and a using method thereof. The synchronous different-direction-type double core pulling sliding block mechanism comprises a pressing block pull rod screw, a double trapezoidal pressing block, 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 simultaneously and synchronously conduct inner-outer core pulling. By adoption of the mechanism provided by the technical scheme, inner-outer core pulling needing to be conducted on the same wall face of a product is integrated into synchronous core pulling of the same core pulling mechanism, the layout space of mold design is saved, the mold design size is decreased, the manufacturing cost of mold production is reduced, the structural design is reasonable, the structure is compact, work is stable, safety and reliability are achieved, and using is convenient.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 2015102156875, the invention name: a synchronous and counter-directional double core-pulling slider mechanism, and the application date: May 01, 2015. technical field [0002] The invention relates to the field of injection mold mechanism design and its use method, in particular to a synchronous and different-direction double core-pulling slider mechanism and its use method. Background technique [0003] 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...

Problems solved by technology

[0003] 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.
