Abstract
The invention provides a mold evacuating device for an injection molding machine, and an operating method of the mold evacuating device. The mold evacuating device comprises an equipment main body, a vacuum pump, a negative pressure tank, a one-way valve and a controller. The operating method of the mold evacuating device for the injection molding machine comprises the steps that when a movable mold is 0.5-2mm away from a fixed mold, an injection molding machine host transmits a control signal to the controller; the controller transmits a start-up command to the one-way valve; the one-way valve is opened; the vacuum pump runs; air in a mold cavity is drawn into the negative pressure tank; the interior of the mold cavity is vacuum; the injection molding machine host transmits mold assembly information to the controller; the controller transmits a close command to the one-way valve; the one-way valve is closed; and the vacuum pump stops running. With the adoption of the technical scheme, the density and surface accuracy of a mold product can be improved; the problem that exhaustion, a flow line, charring and mold filling are poor is solved; a product filling effect can be improved greatly; and the product quality is improved.

Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the mould vacuum extractor and the method for work thereof that provide a kind of injection machine to use, bad and fill the phenomenons such as type is bad to solve exhaust in the mold injection process, to improve the goods filling effect, improve product quality.
Technical scheme of the present invention is:
The invention provides the mould vacuum extractor that a kind of injection machine uses, comprise equipment body, vavuum pump, negative-pressure cup, check valve, controller, described vavuum pump, negative-pressure cup, check valve, controller are fixedly arranged on respectively on equipment body, the output channel of described vavuum pump is communicated with negative-pressure cup, the output channel of described negative-pressure cup is connected with mould, on the output pipe of described negative-pressure cup and described mould, check valve is set, described check valve is connected with controller.
Further, for preventing mould vacuum extractor pressure overload, on described equipment body, pressure-display device is set.
Further, for realizing the mould vacuum extractor, with injection machine, be connected, described controller is connected with the injection machine main frame.
Further, the output channel of described negative-pressure cup is communicated with dynamic model.
Further, for convenient, the mould vacuum extractor is moved to required any position, described mould vacuum extractor bottom is provided with universal caster wheel.
The invention allows for the method for work of the mould vacuum extractor of injection machine use, this method of work comprises:
Step 1: dynamic model near 0.5～2 millimeter of cover half apart from the time, injection machine main frame transmission of control signals is to controller;
Step 2: the order of controller transmission start is to check valve, one-way valve opens, and the vavuum pump operation, by mould
