Description

Technical Field

[0001] The utility model relates to the technical field of processing devices. Background Art

[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying to obtain a molded product.

[0003] In order to facilitate the injection of ammoniated aluminum ceramics, it is necessary to use a nozzle produced by injection molding. After the injection molding is completed, the nozzle produced by injection molding will cause the raw materials to adhere to the connection between the upper mold and the lower mold due to excessive injection material or unstable operation during injection molding. After the injection molding is completed and cooled, these raw materials will also adhere to the connection between the upper mold and the lower mold, making it difficult to separate the upper mold and the lower mold.

[0006] Preferably, the power member comprises a push rod motor, an output end of the push rod motor is fixedly connected to a steel sheet, and an outer wall of the push rod motor is fixedly connected to a fixing plate.

[0007] Preferably, the support plate member includes a base plate, a movable plate and a screw rod, the outer wall of the push rod is rotatably connected to the base plate, the outer wall of the base plate is slidably connected to the movable plate, the outer wall of the movable plate is rotatably connected to the screw rod, the outer wall of the screw rod is threadedly connected to the base plate, and the outer wall of the movable plate is fixedly connected to the fixed plate.

[0008] Preferably, the outer wall of the push rod motor is covered with a protective shell.

[0009] Preferably, one end of the steel sheet is provided with a bevel.

[0010] Preferably, the outer wall of the moving plate and the outer wall of the bottom plate are both provided with anti-slip grooves.

[0011] Preferably, one end of the push rod is fixedly connected to a handle.

[0012] Preferably, the outer wall of the handle is perpendicular to the push rod.

[0013] The beneficial effects of the utility model are:

[0014] 1) Screw the push rod thread into the screw tube, first hold the moving plate or bottom plate by hand, turn the push rod, so that the push rod pushes the support plate to move, and the support plate pushes the steel sheet to move. The steel sheet will cut the raw materials adhered to the upper and lower dies, and then start the push rod motor to move the steel sheet horizontally to completely cut the raw materials adhered to the upper and lower dies, so that the upper and lower dies can be easily separated.

[0015] 2) By rotating the screw, the screw drives the movable plate to move, and the movable plate drives the fixed plate to move, thereby adjusting the height of the steel sheet so that the steel sheet can be aligned with the contact point between the upper and lower dies, thereby facilitating the cutting of the raw materials adhered to the upper and lower dies.
