Description
Technical Field
The utility model relates to a field of moulding plastics especially relates to an injection mold.
Background
The following disadvantages currently exist: injection molding is a method of producing moldings from industrial products, which are usually used Rubber compositionInjection molding and plastic injection molding, and the injection molding can be divided into injection molding method and die casting method, wherein an injection molding machine (an injection machine or an injection molding machine for short) is used for manufacturing thermoplastic plastics or thermosetting materials into plastic products with various shapes by utilizing a plastic molding dieIn actual production, when the adhesive force and the wrapping force of some plastic parts to a movable mould and a fixed mould are not different, the plastic parts are possibly left on one side of the movable mould and one side of the fixed mould after mould opening, so that the demoulding difficulty is caused, and the working efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an injection mold.
The utility model discloses a realize through following technical scheme:
the utility model provides an injection mold, its characterized in that, including the cover half that is equipped with the mouth of moulding plastics and through first cylinder with the movable mould group that the cover half is connected, the cover half both sides all are equipped with the gyro wheel, gyro wheel and arc pole butt, the cover half in the mouth bilateral symmetry of moulding plastics is equipped with the recess, the movable mould group includes first movable mould and second movable mould, the inside chamber of moulding plastics that is equipped with of first movable mould, first movable mould both sides all be equipped with the spring and with the arc pole links to each other, the second movable mould is just right it is equipped with the stripper block to mould plastics the chamber position, second movable mould bilateral symmetry is equipped with the second cylinder, the second cylinder other end links to each other with the fixed plate, be equipped with two demoulding poles and embedding on the fixed plate the second movable mould.
And the outer ring of the roller is provided with damping.
The lower end of the arc-shaped rod is provided with a first wedge-shaped block, and the arc-shaped rod is hinged with the first movable die.
And second wedge blocks matched with the first wedge blocks are arranged on two sides of the second movable die.
The utility model has the advantages that: through the setting of gyro wheel and arc pole for make earlier when the die sinking make the plastic part break away from the cover half, the goods stays on the movable mould limit after the die sinking, then releases the plastic part from the movable mould limit, avoids the drawing of patterns difficulty that the adhesive force and the package tight power of plastic part to movable mould and cover half caused when the phase difference is not too much.
