When mould, thimble opposite dynamic model under top plate effect is moved up, and product is ejected from type chamber, is taken out after separating convenient for product with dynamic model
Product.
Preferably, being equipped with sliding guide column between the dynamic model and top plate, the sliding guide column is equipped with reset spring.This
Sample, sliding guide column can be oriented to moving up and down for dynamic model, guarantee that thimble displacement is accurate, reset spring can move up top plate
Top plate is moved down into reset later.
Preferably, the center of the thimble is equipped with the internal diameter for being equipped with and being slidably matched along axial through-hole, the through-hole
The upper end of needle, the internal diameter needle is extend into type chamber, and lower end and the dynamic model of internal diameter needle are fixed.In this way, internal diameter needle is located at thimble
Inside, thimble can guarantee that internal diameter pin position is accurate to internal diameter needle auxiliary positioning.
It is slided preferably, the mode is equipped with the T shape being slidably matched with the first sliding block, the second sliding block and third sliding block
Road.When die sinking and molding, the first sliding block, the second sliding block and third sliding block opposite sliding, T shape slideway can be protected in T shape slideway
Slider displacement accuracy is demonstrate,proved, while overall structure is more compact.
Preferably, the inner end of first sliding block, the second sliding block and third sliding block is respectively equipped with type cavity portion, the type
Cavity portion is equipped with the corresponding circular arc side wall of 120 degree of central angles of the type chamber, and the two sides of type cavity portion are respectively equipped with perpendicular pipes' analysis, adjacent
Perpendicular pipes' analysis forms the side gate after close contact and erects runner.Since circle product external is equipped with thread, the first sliding block, the
Two sliding blocks and third sliding block use mode as carrier, are stitched to mode using coordinate and grind overall processing, it is ensured that the circularity of thread
And post exercise torsional forces is stablized repeatedly, even if even mould sticking to mould power is big before product, product can normally demould production.
Preferably, the cross section that the side gate erects runner is in water-drop-shaped, water-drop-shaped tip is towards the center of type chamber, water
The arc section of shape is dripped towards on the outside of type chamber.It in this way in die sinking, can be smoothly detached between adjacent sliding block, guarantee that product smoothly takes off
Mould.
The beneficial effects of the utility model are: (1) ensure that lens barrel itself by 3 points of chargings among lens barrel waist
Filling uniformly, effectively controls the fluctuation such as circularity, concentricity and diameter of product, and keep internal diameter needle smaller by stuffing pressure；(2)
The thread of lens barrel is designed using three valves, and convenient for assembly mode overall processing thread, the circularity and stabilization of thread is effectively ensured；(3)
Three sliding block T shape arrangements can shorten ranking, reduce cold (useless) material, promote stock utilization, while being conducive to filling and stablizing, guarantee
Processing effect；(4) setting side gate is erected and is broken from there at runner and spot pouring mouth separation convenient for plastics when die sinking, conveniently passes through machine
Tool hand draws jig using the perpendicular runner taking-up product of suction side gate, and avoiding the air-breathing of jig or blowing influences product
