[0002] Some metal parts, such as metal sheet 30, need to be injection molded together in the injection molding machine, so that a combination of metal parts and plastic can be formed. Later, the desired product can be obtained by cutting off the plastic sprue and some redundant structures of the metal parts. The sprue is conventionally cut with a hot melt cutter, and cutting off the metal parts usually requires stamping with a stamping equipment or manual cutting with pliers. Therefore, the sprue cutting and stamping are performed at different stations, which makes the entire production process more complicated. The utility model proposes an injection molding sprue punching device that can cut the sprue and cut off the metal sheet 30 at the same time. Summary of the invention

In addition, in the utility model, while cutting off the water outlet material, the pressing block can press the metal sheet on the side of the cut water outlet material, and press the metal sheet down by using a lifting pressure knife to cut the metal sheet. In the cutting process, the metal sheet is first bent and then broken. Since the oblique telescopic block can support the bottom of the metal sheet from top to bottom, it can assist in bending the metal sheet. Finally, the metal sheet to be cut is supported by the lifting pressure knife and the oblique telescopic block from top to bottom. Therefore, as the lifting pressure knife is continuously pressed down, the metal sheet will be cut into two pieces. In the utility model, the water outlet cutting component completes the cutting of the water outlet material and the cutting of the metal sheet at one time, with high efficiency and good effect.

The lifting hot cutting knife is a conventional tool for cutting water outlets; the second lifting motor can drive the second lifting mounting plate to rise and fall, so the lifting pressure knife can be uniformly lowered and used in conjunction with the oblique telescopic block to cut the metal sheet, wherein the telescopic action of the oblique telescopic block is preset, and the telescopic length will change in conjunction with the lifting height of the lifting pressure knife. The purpose is that when the metal sheet is pressed down, the oblique telescopic block can always press against the bottom of the metal sheet until the metal sheet is pressed down and broken by the lifting pressure knife.

[0008] Furthermore, the first lifting installation plate and the second lifting installation plate are the same component, and the first lifting motor and the second lifting motor are the same component.

[0009] Furthermore, the pressing block is L-shaped and is fixedly arranged at the lower part of the lifting frame.

This position is generally defined as the water cutting station. The loading slide can also be moved away from the water cutting station to unload the product after cutting. It is generally connected to the unloading robot to take the product away.

[0013] Furthermore, the equipment frame is provided with a material drop bin directly below the lifting hot cutting knife.

[0016] In the above scheme, the first bin body is located directly below the lifting hot cutting knife when the water outlet cutting module is cutting the water outlet, and the second bin body is located directly below the lifting hot cutting knife. The lower parts of the first bin body and the second bin body have opposite inclination angles, so the falling materials will come out from different positions, so that the cut water outlet material and a part of the broken metal sheet can be screened.

[0017] Furthermore, the material loading slide comprises a loading plate, a material dropping chute hole is arranged on the loading plate, and the top of the oblique telescopic block is located in the material dropping chute hole.
