Description

Technical Field

[0001] The utility model belongs to the field of molds, and particularly relates to a forming mold for a radiator housing. Background Art

[0002] A radiator is an important and most basic component in a hot water heating system. Hot water cools down in the radiator and supplies heat to the room to achieve the purpose of heating. The metal consumption and cost of the radiator account for a relatively large proportion in the heating system. In the production of radiators, their outer shells are usually produced by injection molding, and a mold is usually required during injection molding.

[0003] In the prior art, for a forming mold of a radiator housing, after the mold is cooled, the model will adhere to the mold, which makes it difficult to take out the radiator housing produced in the lower mold. It is not convenient for demolding and not convenient for operators to operate.

[0004] To avoid the above technical problems, it is necessary to provide a forming mold for a radiator housing to overcome the defects in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a forming mold for a radiator housing, aiming to solve the problem of inconvenient demolding.

[0006] An embodiment of the utility model is implemented as follows. A forming mold for a radiator housing includes a base, a support frame fixedly connected to the base, a screw rod threadedly connected to the support frame. One end of the screw rod close to the base is rotatably connected to a mounting plate. A upper mold is fixedly connected to the bottom of the mounting plate. An injection port is provided on the upper mold. A lower mold is fixedly connected to the base. A demolding plate is slidably connected to the inside of the lower mold. It further includes:

[0007] A driving mechanism installed on the support frame. The output end of the driving mechanism is connected to the screw rod. The driving mechanism is used to drive the screw rod to rotate, and the screw rod drives the mounting plate to move up and down.

[0008] A demolding mechanism installed on the base. The output end of the demolding mechanism can abut against the demolding plate. Second through holes and first through holes for the output end of the demolding mechanism to pass through are respectively formed on the base and the lower mold. After the mold is cooled, the demolding mechanism can drive the demolding plate to rise, and the demolding plate drives the model to rise, which is convenient for demolding of the model.

[0009] Further technical solution: The driving mechanism includes a worm gear slidably connected to the screw rod. A keyway adapted to the worm gear is provided on the screw rod. The worm gear is rotatably connected to the support frame through a bearing seat. A vertical block is fixedly connected to the support frame. A first rotating rod is rotatably connected to the vertical block. A worm is fixedly connected to the first rotating rod. The worm is meshed with the worm gear. One end of the first rotating rod is fixedly connected to a first handwheel.

[0010] Further technical solution: It further includes two guide rods. Both of the two guide rods penetrate and are slidably connected to the support frame. One end of each of the two guide rods is fixedly connected to the mounting plate.

[0011] Further technical solution: The demolding mechanism includes a fixed frame fixedly connected to the bottom of the base. A lifting plate is slidably connected to the fixed frame. A top column is fixedly connected to the top of the lifting plate. The diameter of the top column is smaller than the diameters of the first through hole and the second through hole, and one end of the top column can abut against the demolding plate. A cross plate is fixedly connected to the fixed frame. The top column penetrates the cross plate. A compression spring is connected between the lifting plate and the cross plate. A second rotating rod is rotatably connected to the fixed frame. A cam is fixedly connected to the second rotating rod. The cam contacts the lifting plate. One end of the second rotating rod is fixedly connected to a second handwheel.

[0012] Further technical solution: There are multiple top columns. The multiple top columns are equidistantly distributed on the lifting plate, and the multiple lifting plates make the demolding plate receive balanced force.

[0013] Further technical solution: A retaining ring is fixedly connected to the bottom of the mounting plate. An annular groove adapted to the retaining ring is provided at the bottom of the lower mold. The retaining ring is used to enhance the sealing of the lower mold and prevent leakage between the upper mold and the lower mold.
