Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of can improve the uniformity of goods material and the dimensional stability of goods, reduces the residual stress of working of plastics simultaneously, reduces the compression injection molding machine of fraction defective;
Another object of the present invention is to want the method for using of above-mentioned compression injection molding machine.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of compression injection molding machine; It comprises moving, decide injection moulding machine template; Move, decide to be installed with respectively on the injection moulding machine template moving, fixed mold; Said moving injection moulding machine template opposite side is fixedly connected with code mask, and code mask adopts dovetail groove to be connected with upper and lower tiltedly carving between the piece, and said upper and lower tiltedly carving is connected with the driving mechanism that can do to pump respectively on the piece;
As the further improvement to above-mentioned embodiment, the die cavity both sides of said moving mold are provided with reference column, are set with spring and rocker piece on the reference column successively.
The method for using of above-mentioned compression injection molding machine, its step is following:
1), will move, the fixed mold matched moulds, make die joint moving, fixed mold be in contact with one another, make the gap between it form the plastic parts moulding space;
2), through driving mechanism motion, make the upper and lower piece of tiltedly carving drive mould through code mask and outwards move, the die cavity space that make, the gap between the fixed mold forms a part wall thickness twice;
3), with the resin implantation step 2 of molten condition) in the die cavity that forms;
4), through driving mechanism toward swivel motion, make the upper and lower piece of tiltedly carving drive mould through code mask and move inward, die joint moving, fixed mold is in contact with one another, thereby with resin compression forming in die cavity.
The invention has the beneficial effects as follows: thus the present invention transforms the realization compression injection molding on common injection machine; This design can provide bigger streamer length of mould and wall thickness ratio, reduces clamp force and injection pressure, can on littler injection-moulding device, make large-scale plastic parts; And can also effectively improve the uniformity of goods material and the dimensional stability of goods; Reduce the residual stress of working of plastics simultaneously, significantly reduce fraction defective, thereby can be widely used in the making of flat-type thin-wall product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of this compression injection molding machine;
Fig. 2 is the structural representation of this compression injection molding machine resin injection state;
Fig. 3 is the structural representation of this compression injection molding machine compression forming state.
The specific embodiment
With reference to Fig. 1; A kind of compression injection molding machine, it comprise moving, decide injection moulding machine template 1,2, moving, decide to be installed with respectively on the injection moulding machine template 1,2 moving, fixed mold 8,9; Said moving injection moulding machine template 1 opposite side is fixedly connected with code mask 7; Code mask 7 with upper and lowerly tiltedly carve piece 5, adopt dovetail groove to be connected between 6, said upper and lower tiltedly carving is connected with the driving mechanism 3,4 that can do to pump respectively on the piece 5,6, driving mechanism 3,4 can adopt drive forms such as oil cylinder, cylinder; Reach technique effect of the present invention with essentially identical means in a word, all should belong to protection scope of the present invention.
This product is when preventing in moving, fixed mold 8, the die cavity space that forms between 9, to inject resin; Leakage phenomenon appears; The die cavity both sides of said moving mold 8 are provided with reference column; Be set with spring 81 and rocker piece 82 on the reference column successively, this design make rocker piece 82 all the time roof pressure on fixed mold 9, thereby play the purpose of closed type cavity space.
With reference to Fig. 2, Fig. 3, the method for using of above-mentioned compression injection molding machine, its step is following:
1), will move, fixed mold 8,9 matched moulds, make die joint moving, fixed mold 8,9 be in contact with one another, make the gap between it form the plastic parts moulding space;
2), through driving mechanism 3,4 motion, make the upper and lower piece 5,6 of tiltedly carving drive moulds 8 through code mask 7 and outwards move, the die cavity space that make, fixed mold 8, the gap between 9 forms a part wall thickness twice;
3) in the die cavity that, the resin implantation step of molten condition 2 is formed;
4), through driving mechanism 3,4 toward swivel motions, make the upper and lower piece 5,6 of tiltedly carving drive moulds 8 through code mask 7 and move inward, die joint moving, fixed mold 8,9 is in contact with one another, thereby with resin compression forming in die cavity.
For ease of the present invention is further understood, combine specific embodiment to describe the present invention at present.
During the LCD transparent panel, its step is following when needs make 42:
