Technical Field

The invention belongs to the field of injection molds, and particularly relates to a mold opening mechanism of an injection mold.

Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. When the injection mold opens the mold, generally push away upper template, make upper template and lower floor's template separation, the double-deck module die sinking is fairly simple, but when the three-layer template die sinking, need separate upper, middle and lower three-layer template, only need to lean on manual separation promptly will go up template and well template separation and well template and lower bolster separation, and the power consumption is wasted time, leads to production efficiency to hang down.

Disclosure of Invention

The invention provides a mold opening mechanism of an injection mold, and aims to solve the problem that the mold opening of a three-layer template is difficult.

The invention is realized in such a way, an injection mold opening mechanism comprises a pressure cylinder, a bottom plate is fixed on the pressure cylinder, mold locking side plates are hinged on two sides of the bottom plate through a rotating shaft, one side of each of the two mold locking side plates is fixedly connected with one end of a mold locking arm, the other end of the mold locking arm is fixedly connected with the output end of a first air cylinder, the first air cylinder is fixed on the bottom plate, the mold locking arm is rotatably connected with the rotating shaft, a plurality of guide columns are fixed on the bottom plate, the guide columns are arranged on the bottom plate in pairs and are close to the mold locking side plates, each guide column is provided with a guide rod seat plate through a guide rod seat, a middle mold plate is arranged between the two guide rod seat plates, the front end of the middle mold plate is provided with a drag hook, an injection molding device is fixed on the pressure cylinder, a lower mold plate is fixed on the injection, a plurality of upset arm one end is fixed with the upset template, the second cylinder is installed to pressure cylinder one side, the second cylinder output fixed connection upset arm other end, upset template below is fixed with the cope match-plate pattern, upset template front end fixed mounting has the lifting hook, the lifting hook passes through the drag hook circle with the drag hook and is connected.

Furthermore, limiting baffles are fixed on two sides of the pressure cylinder.

Further, the mold locking arms are L-shaped.

Furthermore, a plurality of turning plate stop blocks are arranged on the back side of the support arm.

Furthermore, the two sides of the turnover template are provided with convex blocks, and the two sides of the mold locking side plates are provided with clamping grooves.

Still further, the first cylinder and the second cylinder are both single rod cylinders.

Furthermore, the guide rod seat plate is provided with a containing groove, and one end of each of the guide rod seats is provided with a sliding block which is arranged in the containing groove of the guide rod seat plate.

Has the advantages that: promote upset module and cope match-plate pattern upset through the second cylinder, separate cope match-plate pattern and well template, through the shrink of pressure cylinder output, make the device of moulding plastics on the pressure cylinder and follow the downward movement of pressure cylinder output with the lower bolster, template and lower bolster in the separation realize the separation of three-layer module, through cylinder output, easy operation.
