Description

Technical Field

[0001] The utility model relates to the field of supporting equipment for injection molding machines, in particular to a nozzle cutting machine for injection molding parts. Background Art

[0002] The sprue refers to the joint between the frame and the part when casting the model. It is the connecting port between the heated liquid plastic and the runner. In the injection molding process, the high-temperature molten plastic needs to enter the mold cavity from the injection molding machine nozzle through the sprue to form a product with the desired shape. After the liquid plastic cools and solidifies, the runner forms a frame, and the plastic at the connection between the frame and the product forms a sprue. When using the product, the molded product needs to be cut off from the sprue to obtain the desired product.

[0003] For example, a patent with authorization announcement number CN220095409U discloses a water cutting device, including a box body, a drawer, a carrier plate, a guide shaft, a sliding plate, a through groove, a top plate, a cylinder, a push rod, a movable joint, a blade, and a blade fixing plate; the interior of the box body is hollow, and a drawer is provided on one side. A carrier plate is provided at the top opening of the box body, a guide shaft is provided at the top corner of the box body, a sliding plate is provided on the guide shaft above the box body, and a top plate is provided at the end of the guide shaft above the sliding plate. A cylinder is provided on the top plate, and the push rod on the cylinder passes through the hole on the top plate and is connected to the movable joint. The other end of the movable joint is fixed to the sliding plate, and a through groove is also provided on the sliding plate. The blade fixing plate is fixed to the through groove by bolts, and the blade is fixed to the blade fixing plate.

[0004] The above patent uses a blade fixing plate to fix the blade fixing plate on the through slot on the sliding plate by bolts. The through slot is long and narrow, so that the spacing between the blades can be changed by adjusting the position of the blade fixing plate on the through slot, so that the device can adapt to the gate cutting of injection molded parts of different sizes;

[0005] However, the disadvantage of the above patent is that the workpieces dropped after the water cut are collected by a drawer, and the worker needs to pull the drawer to take out the product, which increases the steps of the work and is not conducive to improving work efficiency.

[0006] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
