Abstract
The invention relates to a rapid mold-opening injection mold of a small plastic gear and belongs to the technical field of injection molds. The rapid mold-opening injection mold comprises a work bench, an upper injection molding mold and a lower injection molding mold matching with the upper injection molding mold. The lower injection molding mold is installed on a lower mold plate. The lower mold plate is installed on the work bench. The top of the upper injection molding mold is installed on an upper mold plate. The parts of the work bench at left and right sides of the lower mold plate are respectively provided with vertical guide pillars. The guide pillars are sleeved through guide sleeves. The guide sleeves are respectively fixed to the corresponding upper mold plate. The upper injection molding mold is sleeved through a thermal insulation sleeve. The thermal insulation sleeve is prepared from an aluminum alloy material. The guide pillars are sleeved through rubber sleeves for rapid mold opening. A screw is vertically arranged between the thermal insulation sleeve and the guide pillar at the left side. The upper end of the screw goes through the upper mold plate through a bearing. The screw is sleeved through a nut matching with the screw. The nut is fixed to a support. The rapid mold-opening injection mold improves a product qualified rate through use of the thermal insulation sleeve.
Description
Technical field
The present invention relates to a kind of injection mold of quick die sinking of small plastic gear, belong to injection mold technical field.
Background technology
Gear drive is a kind of kind of drive common during people live, and its transmission stability is very high, and service life is longer.Along with the continuous progress of science and technology, also get more and more with the gear of plastic production, be mainly used in the little industry of driving torque, its production cost is low, and cost of transportation is low, and safety and safeguarding also facilitates.The production method that plastic gear is commonly used at present adopts injection mold to carry out injection mo(u)lding exactly, speed of production is fast and qualified products are very high, but current gear injection mold affects by ambient temperature when production injection moulding, the gear produced there will be hollow phenomenon sometimes, thus affect the service life of gear, and affect the image of enterprise product.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: the injection mold providing a kind of quick die sinking of small plastic gear, its structure is simple, when gear injection moulding, certain insulation effect is had to its environment temperature, decrease the hollow phenomenon occurred in the middle of injection moulding gear out, improve the qualification rate of product.
The injection mold of the quick die sinking of small plastic gear of the present invention, the injection mold of the quick die sinking of small plastic gear, comprise workbench, the injection moulding patrix cooperatively interacted and injection moulding counterdie, injection moulding counterdie is arranged on lower bolster, lower bolster is installed on the table, injection moulding patrix top is arranged on cope match-plate pattern, the workbench of the lower bolster left and right sides is vertically provided with guide pillar respectively, all guide pin bushing is set with at guide pillar, guide pin bushing respectively correspondence is fixed on cope match-plate pattern, it is characterized in that: in injection moulding patrix periphery, cover has muff, muff is that aluminum alloy materials makes, on guide pillar, cover has the rubber sleeve for fast open mould, the apical side height of rubber sleeve is than injection moulding counterdie apical side height height 10mm ~ 30mm, the sleeve wall thickness of rubber sleeve is 20mm ~ 30mm, a screw rod is vertically provided with between muff and the guide pillar in left side, screw rod upper end is installed on cope match-plate pattern by bearing, on screw rod, cover has the nut matched with it, nut is fixed on support, support installing on the table, screw rod lower end is provided with the handle chassis for rotating.
In order to guarantee be incubated while can also guarantee injection moulding complete after cooling shaping, the sleeve wall thickness of preferred described muff is 30mm ~ 50mm.
In order to guarantee heat insulation effect further, bottom preferred described injection moulding patrix, equal the height of injection moulding counterdie from the distance bottom muff.
Further preferred described injection moulding counterdie can be enclosed within muff.Accelerate the heat radiation in injection moulding aftershaping stage.
The beneficial effect that the present invention has is:
By the present invention, its structure is simple, when gear injection moulding, under the effect of muff, has certain insulation effect to its injection moulding environment temperature, decreases the hollow phenomenon occurred in the middle of injection moulding gear out, improves the qualification rate of product.The die sinking work after gear injection mo(u)lding is effectively facilitated under the elastic reaction of rubber sleeve, time saving and energy saving.What adopt due to the matched moulds between injection moulding patrix and injection moulding counterdie is manual mode; therefore equipment making cost is low; be applicable to very much the processing of pinion; coordinating by screw rod and nut during use, screw rod is moved up or down thus die sinking completely between injection moulding patrix and injection moulding counterdie or matched moulds work.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
In figure: 1, injection moulding patrix 2, muff 3, cope match-plate pattern 4, guide pillar 5, guide pin bushing 6, injection moulding counterdie 7, lower bolster 8, workbench 9, rubber sleeve 10, handle chassis 11, support 12, nut 13, screw rod.
Detailed description of the invention
Below by way of specific embodiment, the invention will be further described, but not in order to limit the present invention, all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
