Description
Technical field
Transverse slider and product the present invention relates to the core-pulling demolding device of injection mold, in particular to for injection mold
A kind of Two Steps Core Pulling device of injection mold polyisocyanate core body transverse slider of core pulling separation.
Background technology
The core_pulling demoulding of injection mold point longitudinally, laterally with it is oblique, so-called longitudinal direction be along the folding direction of injection mold,
So-called transverse direction is the direction orthogonal with the longitudinal direction, the so-called oblique direction between longitudinal direction and transverse direction.Transverse slider is
Slip is located above the dynamic model support plate of injection mold, is slid laterally during work, the slip for moulded products lateral surface shape
Core member；The demoulding in transverse slider type face, prior art use direct core_pulling demoulding, however, laterally sliding for polyisocyanate core body
Block, i.e. type surface side is provided with the transverse slider for the polyisocyanate core body that multiple protrusion, mutual compact parallel and length differ greatly, directly
Core_pulling demoulding easily pulls product, and the defective products and percent defective for causing product occupy height, and therefore, it is high, useless that prior art has defective products
The problem of product rate is high and deficiency.
The content of the invention
For the above-mentioned problems of the prior art with deficiency, the present invention using by long core sliding block, short core sliding block, key,
The device that lock pin, spring are formed, i.e. transverse slider is divided into two parts of long core sliding block and short core sliding block, wherein, long core sliding block
Provided with long core, oblique guide hole and tie rod hole；Short core sliding block is provided with short core, pull bar, pin-and-hole；Long core sliding block is located at the right side of short core sliding block
