Description

Technical Field

[0001] This utility model relates to the field of molding die equipment technology, and in particular to a thermosetting molding die equipment with multi-layer heating and uniform pressure distribution. Background Technology

[0002] The main function of thermosetting molds is to mold thermosetting plastics into the required shapes and sizes. Specifically, thermosetting molds use heat and pressure to solidify thermosetting plastics within the mold, thereby producing high-performance parts with durable and high-temperature resistant properties.

[0003] Current hot pressing molds mainly heat one of the molds when the upper and lower molds are fitted together, usually the upper mold. This method of heating requires a certain amount of preheating time, resulting in low heating efficiency and an inability to quickly spread the heat. There is room for improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a multi-layer heating and uniform pressure distribution thermosetting mold equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A lower hot pressing film is fixed to one side of the top of the base plate via support feet. Guide rods are fixed around the lower hot pressing film on the top of the base plate. A top plate is fixed to the top of the guide rods. An upper hot pressing film driven by a cylinder is installed on the top plate. A second bracket is fixed to one side of the top of the base plate. An air pump is fixed to the top of the second bracket. The air pump is connected to the upper and lower hot pressing films via an air supply pipeline. Both the upper and lower hot pressing films are hollow structures.

[0007] As a further embodiment of this utility model, the cylinder is fixed to the top of the top plate, a movable plate is fixed to the output end of the cylinder, the upper hot press film is installed below the movable plate, and a hole is opened on the top of the top plate for the cylinder output end to pass through.

[0008] As a further embodiment of this utility model, holes are provided at the four corners of the bottom of the movable plate, and a sliding sleeve is fixed at the bottom of the hole, through which the guide rod passes.

[0009] As a further embodiment of this utility model, a connecting block is fixed to the bottom of the movable plate, and the bottom of the connecting block is fixed to the top of the upper hot-press film.

[0010] As a further embodiment of this utility model, the gas supply pipeline includes a three-way connector fixed to the gas pump outlet port. A second solenoid valve is fixed to the bottom port of the three-way connector, and a gas delivery pipe is fixed to the other end of the second solenoid valve. The gas delivery pipe is connected to the bottom of the lower hot press film. A first solenoid valve is fixed to the other port of the three-way connector. The first solenoid valve is connected to a gas inlet pipe. A connector is fixed to the other end of the gas inlet pipe. A flexible hose is connected to the connector. The other end of the flexible hose is fixedly connected to the outer side of the upper hot press film.

[0011] As a further embodiment of this utility model, air holes are provided at the top of both the upper and lower hot-pressing films to release air pressure and prevent excessive internal air pressure.
