Technical Field

The utility model relates to an injection mold designs technical field, specifically is an efficient injection mold.

Background

An injection mold is a tool for producing plastic products; the injection molding is a processing method used for batch production of parts with complex shapes, and particularly relates to a method for injecting a material melted by heating into a mold cavity from high pressure, and obtaining a formed product after cooling and solidification.

However, during injection molding, molten material is solidified in advance, and material flow is influenced; air remained in the die cavity is easy to cause air holes on a finished product; long cooling and solidifying time of the injection molding material, uneven cooling part, low production efficiency and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an efficient injection mold to solve the defect that the material that is heated solidifies in advance, cooling curing time is long and the finished product has the gas pocket.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the efficient injection mold is characterized in that a movable mold core is arranged on the movable mold plate, a fixed mold core is arranged on the fixed mold plate, a cavity is formed between the movable mold core and the fixed mold core, an injection molding hole communicated with the cavity is formed in the top of the movable mold plate, a heating block and an air exhaust valve are arranged at the upper end of the cavity, the heating block (6) and the air exhaust valve are fixedly connected to the movable mold core, a cooling cavity is formed in the fixed mold plate, and a plurality of guide pillars connected with the movable mold plate are arranged on the fixed mold base.

Furthermore, the movable mould plate and the fixed mould base are respectively provided with four positioning pins which are distributed on the periphery.

Furthermore, four damping springs fixedly connected with the fixed die plate are arranged in the middle of the fixed die base, and the pressure of the movable die plate on the fixed die plate can be relieved when the die is closed.

Furthermore, the heating block is connected with an air conveying port arranged at the top of the movable template through an air conveying pipe; and the air exhaust valve is connected with an air outlet arranged at the side end of the movable template through an air outlet pipe.

Furthermore, the cooling cavity surrounds the cavity, and a liquid injection hole and a liquid outlet hole are respectively formed in two ends of the outer side of the fixed die plate.

The utility model has the advantages that: the utility model provides an efficient injection mold, when the compound die was moulded plastics, heat through the heating piece and let in steam to the die cavity that constitutes between movable mould core and the cover half core, carry out the heating to the mould, when treating to heat the uniform temperature, the bleeder valve begins work, take away steam and the air of die cavity, after forming the vacuum die cavity, the hole of moulding plastics begins to pour into the material that is heated and melts, when the die cavity is filled with the material, the coolant liquid lets in the cooling chamber mesocycle flow in the cover half through annotating the liquid hole, evenly cools off the finished product. This practicality can avoid being heated through the mould heating and melt the material and solidify in advance during moulding plastics, through taking out the intracavity gas of removing, prevent that the gas pocket from appearing in the finished product and encircle the design of mould cooling chamber and reach the even cooling effect of finished product.
