Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides and a kind ofly can improve the uniformity of goods material and the dimensional stability of goods, reduce the residual stress of working of plastics simultaneously, reduce the compression injection molding machine of fraction defective;
Another object of the present invention is to want the using method 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 comprise moving, decide injection moulding machine template, move, decide to be installed with respectively on the injection moulding machine template moving, fixed mold, described moving injection moulding machine template opposite side is fixedlyed connected with code mask, code mask adopts dovetail groove to be connected with upper and lower tiltedly carving between the piece, described 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 described moving mold are provided with reference column, are set with spring and rocker piece on the reference column successively.
The using method of above-mentioned compression injection molding machine, its step is as follows:
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), by driving mechanism motion, make the upper and lower piece of tiltedly carving drive mould by 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), by driving mechanism toward swivel motion, make the upper and lower piece of tiltedly carving drive mould by 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, reduce 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
The present invention is further described below in conjunction with drawings and Examples.
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 comprises moving; decide injection moulding machine template 1; 2; moving; decide injection moulding machine template 1; be installed with moving on 2 respectively; fixed mold 8; 9; described moving injection moulding machine template 1 opposite side is fixedlyed connected with code mask 7; code mask 7 is with last; declivity is carved piece 5; adopt dovetail groove to connect between 6; on described; declivity is carved piece 5; be connected with the driving mechanism 3 that to do to pump on 6 respectively; 4; driving mechanism 3; 4 can adopt oil cylinder; drive forms such as 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 to inject resin in the die cavity space that forms between moving, the fixed mold 8,9, leakage phenomenon appears, the die cavity both sides of described 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 using method of above-mentioned compression injection molding machine, its step is as follows:
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), by driving mechanism 3,4 motion, make the upper and lower piece 5,6 of tiltedly carving drive moulds 8 by code mask 7 and outwards move, the die cavity space that make, the gap between the fixed mold 8,9 forms a part wall thickness twice;
3), in the die cavity that the resin implantation step 2 of molten condition is formed;
4), by driving mechanism 3,4 toward swivel motions, make the upper and lower piece 5,6 of tiltedly carving drive moulds 8 by 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, now describe the present invention in conjunction with specific embodiments.
During the LCD transparent panel, its step is as follows when needs make 42:
