Description

Technical Field

[0001] This utility model relates to the field of plastic molds, specifically a fully automatic sprue cutting plastic mold. Background Technology

[0002] Plastic molds are a type of combined mold used in compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes in the mold's punch, die, and auxiliary molding systems allow for the production of a range of plastic parts of different shapes and sizes.

[0003] Currently, in the compression molding process of plastic molds, sprues are required for mold cooling, which results in the sprues having slightly insufficient thermal conductivity. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fully automatic sprue cutting plastic mold includes a top plate with an injection port at the center of the top. A connecting strip is installed on the left side of the top plate, and a cooling seat is fixedly connected to the back of the connecting strip. A cylinder is installed on the back of the cooling seat, and a push rod is installed at the telescopic end of the cylinder. A front block is provided at the front end of the push rod. A connecting strip is fixedly connected to the right side of the top plate, and a cylinder is installed on the back of the connecting strip. A push rod is installed at the telescopic end of the cylinder, and a mold cover is provided at the front end of the push rod.

[0007] As a further embodiment of this utility model: a top strip is fixedly connected to the upper surface of the second connecting strip, and one end of the top strip is located in the inner cavity of the second plate.

[0008] As a further embodiment of this utility model: a plate one is installed at the bottom of the top plate, a plate two is installed at the bottom of the plate one, and a support platform is installed in the middle of the upper surface of the plate two.

[0009] As a further embodiment of this utility model: an injection-molded guide post is installed on the upper surface of the support platform, a cooling seat is installed on the left and right sides of the injection-molded guide post, and a water pipe is installed on the back of the cooling seat.

[0010] As a further embodiment of this utility model: a third plate is installed at the bottom of the second plate, and an electric push rod is installed on the upper surface of the inner frame of the third plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, the operation of cylinder two is used to lift the mold cover upwards, while the operation of cylinder one is used to apply pressure to the mold cover, causing it to loosen. The support platform and injection guide pillars installed in the middle of the upper surface of plate two are fixed in place, and the cooling seats installed on the left and right sides of the injection guide pillars, together with the water pipes, are used to guide water to the cooling seats, so that the cooling seats can cool the mold cover before it is demolded. Its structure is more optimized and its design is more reasonable. Attached Figure Description
