Description

Technical Field

[0001] This utility model belongs to the field of sealing gasket production technology, and in particular relates to an extrusion molding rubber molding die. Background Technology

[0002] A gasket is a sealing component used in machinery, equipment, and pipelines where fluid flows. The main function of a gasket is to prevent fluid leakage through physical blocking. Gaskets are usually made of metal or non-metal sheet materials and are processed by cutting, stamping, or trimming. They are used for sealing connections between pipes and machine equipment components. Molding molds are required in the production process of gaskets.

[0003] A search revealed a rubber extrusion molding die in patent document CN220841142U, comprising a base plate with an L-shaped plate fixedly connected to its top. A demolding mechanism is located on the top of the base plate, and an extrusion assembly is disposed on the inner side of the L-shaped plate. The demolding mechanism includes a U-shaped plate fixedly connected to the top of the base plate, and a base fixedly connected to its top. Two placement slots are formed on the top of the base, and through slots are formed on both the top of the U-shaped plate and the base. Through the design of the extrusion assembly, the die is made of a heat-conducting material. After the rubber part is extruded and plasticized inside the die, the die can be pushed to the top of the base by the operation of a first electric telescopic rod. A fan then cools the outside of the die, rapidly cooling the rubber part inside. This prevents burns to workers when the cooled rubber part is removed.

[0004] The aforementioned rubber extrusion molding die includes an extrusion assembly comprising a horizontal plate disposed on top of a base. Two punches are fixedly connected to the bottom of the horizontal plate, and a second heating wire is fixedly connected to the bottom of the punch's inner cavity. A cylinder is fixedly connected to the top of the horizontal plate, and the top of the cylinder is fixedly connected to the top of the inner side of an L-shaped plate. The second heating wire heats the punches. Two guide rods are fixedly connected to the top of the horizontal plate, both passing through the top of the L-shaped plate. The guide rods limit the horizontal plate's movement, preventing it from shifting. The demolding mechanism includes a U-shaped plate fixedly connected to the top of a base plate, and a base fixedly connected to the top of the U-shaped plate. Two placement slots are provided on the top of the base, and concave molds are placed inside the placement slots. In actual operation, the device is first powered on. After the rubber material to be extruded is placed into the concave mold, the first heating wire heats the top concave mold, while the second heating wire heats the punches. Subsequently, the cylinder operates, pushing the horizontal plate downwards. The horizontal plate moves the punches into the concave mold, thus extruding the rubber material. The material is extruded to thermoform the rubber material. However, it is not convenient to adjust the distribution of raw materials in the production of the sealing gasket, which will result in uneven distribution of raw materials and uneven elasticity of the sealing gasket, and even affect the sealing effect. After the motor is working, it drives the rotating rod to rotate, the rotating rod drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the connecting rod to rotate, and the connecting rod drives the die to flip. After the die is flipped until the demolding hole on the die is in front of the ejector rod, the second electric telescopic rod can push the connecting plate. The connecting plate drives the strip plate to move, and the strip plate drives the ejector rod to move through the demolding hole and eject the rubber part inside the die, thereby achieving the purpose of rapid demolding. Compared with manual demolding, it is simpler and more convenient and saves manpower. However, it is not convenient to cut the extruded sealing gasket, which reduces functionality, and only one sealing gasket can be produced at a time, thus reducing the production efficiency of the sealing gasket.

[0005] To address these issues, we provide an extrusion molding rubber molding die. Utility Model Content
