In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is a kind of plastic part generalized section;
Fig. 2 is the main pseudosection of the disclosed a kind of mould of plastics of the utility model embodiment;
Fig. 3 is the combination schematic diagram of the disclosed inner slide of the utility model embodiment and oblique contract piece.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of mould of plastics (with reference to Fig. 2), comprises fixed half and moving half, and cover half comprises cast gate S, solid plate 12 and fixed mold core B1, and fixed mold core B1 is fixed on the lower end of solid plate 12; Dynamic model comprises moving platen 16, mavable module core B2, plays bar 19 and push pedal 18, and mavable module core B2 is fixed on the upper end of moving platen 16; Be provided with interior mould emptier and outer mould emptier between dynamic model and the cover half.
Interior mould emptier comprises slide block pedestal 13, inner slide A2, oblique contract piece 14, pull bar C2 and cylinder K1; The cross section of slide block pedestal 13 is the isosceles trapezoid shape, and slide block pedestal 13 is positioned on the mavable module core B2.
The cylinder body of cylinder K1 and moving platen 16 are fixing, and its expansion link K2 passes mavable module core B2 and links to each other with slide block pedestal 13.
Inner slide A2 is respectively three with the quantity of oblique contract piece 14, and on the outer rim that is arranged in slide block pedestal 13 that intermeshes (referring to Fig. 3).
Corresponding inner slide A2 place is provided with T-shaped chute on the slide block pedestal 13, is provided with T-shaped boss on the slide block pedestal 13.T-shaped boss is fastened in the T-shaped chute, and can slidably reciprocate in T-shaped chute.The boss of dove-tail form and the chute of dove-tail form cooperatively interact, and also can realize identical function, are not described specifically at this.
The end of pull bar C2 is connected with oblique contract piece 14, and the other end passes mavable module core B2 and moving platen 16 is flexibly connected with push pedal 18.One end of the corresponding push pedal 18 of pull bar C2 is symmetrically arranged with two projections; Being provided with 17, two projections of swinging chute in the push pedal 18 is flexibly connected with the inwall of swinging chute 17 respectively.
Corresponding pull bar C2 place all is provided with lining C1 in mavable module core B2 and the moving platen 16, and lining C1 is set on the outer rim of pull bar C2.After long-time the use, have wearing and tearing between pull bar C2 and mavable module core B2 and the moving platen 16, cause the gap can become greatly, thereby cause the positional precision of oblique contract piece 14 to reduce, and then affect the quality of product; Adding lining C1 can be with pull bar C2 correcting, and if have wearing and tearing only to need more resleeve C1 gets final product, the cost that repairs a die is low.
The top of slide block pedestal 13 is provided with limited block 11, prevents that inner slide A2 breaks away from slide block pedestal 13.
Outer mould emptier comprises outer slide A1 and taper pin; Outer slide A1 is positioned on the moving platen 16, and is slidingly connected with moving platen 16; One end of taper pin and solid plate 12 are fixing, and the other end is arranged in outer slide A1.After the die sinking, taper pin forces outer slide A1 to decorporate backward, finishes the profile demoulding of product D.
After the die sinking, outer slide A1 decorporates backward and finishes the demoulding of product D profile under the effect of taper pin.The expansion link K2 of cylinder K1 regains, and slide block pedestal 13 is extracted out, and inner slide A2 slides at slide block pedestal 13 relatively, slowly gathers to the centre, until break away from product D.When inner slide A2 inwardly gathered, the pressure of filling on oblique contract piece 14 disappeared, and the pressure on the pull bar C2 also can disappear, and pull bar C2 slides in the swinging chute 17 of push pedal 18, and tiltedly contract piece 14 can slowly break away from product D under the effect of pull bar C2.
After the inside and outside all demouldings of product D, the pushing block of injection machine stretches out, and promotes push pedal 18 and advances, and the bar 19 of beating that is fixed in the push pedal 18 ejects product D.Product D can fall under action of gravitation.
The utility model utilizes the position relationship between inner slide, oblique contract piece and the slide block pedestal three, has realized product automatic demoulding, the purpose that reduces production costs, enhances productivity.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
