In the effect that accumulator housing ejects, structure more compactedness.
The present embodiment is fixed with buffer limit block 26 by the end face of described thimble panel 10, prevents from ejecting accumulator
Occur during shell product that top board directly contacts laminating moulding mould vibrations and causes damage of product with template.
By there is back-moving spring 11 between described thimble panel 10 and lower bolster 6 in the present embodiment so that push up during die sinking
Product is ejected after moving up by pin 12, Ejector Retainer Plate 9 and thimble panel 10, and realizes the reset of thimble 12.
Being fixed with jacking block 23 by the bottom surface of described Ejector Retainer Plate 9 in the present embodiment, this jacking block 23 runs through rear mold fixed plate
8 so that the point of stress is more concentrated, improve the effect of thimble 12 ejecting product.
Operation principle: mould is fixed on injection machine, injection machine is divided into standing part and movable part, and mould is at matched moulds shape
During state, front mould is fixed on injection machine standing part, and rear mold is fixed on the movable part of injection machine.Injection molding process is: cope match-plate pattern
3, lower bolster 6 is opened, and drives Angle Pin 19 to move upward, owing to Angle Pin 19 is angled, can drive the first core-pulling slide block 21
With the second core-pulling slide block 24 transverse movement, it is achieved product outer concave convex surface molding；Injection machine push rod pushes away Ejector Retainer Plate 9 and thimble 12
Panel movement, thimble 12 is connected on thimble panel 10 by hanging platform, and thimble panel 10 moves upward, and thimble 12 can be driven to move；
Thimble 12 moves upward, it is achieved product ejection die.Injection mo(u)lding is the process of a circulation, and each cycle specifically includes that
Quantifying feed-fusion plastification-pressure injection-mold filling cools down-opens mould pickup.Take out after plastic mold closing the most again, carry out the next one and follow
Ring.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that under the enlightenment of the present invention other are various
The product of form, no matter but in its shape or structure, make any change, every have same as the present application or akin skill
Art scheme, within all falling within protection scope of the present invention.
