Description
Technical Field
[0001] The utility model relates to the technical field of injection molding part processing, in particular to a device for cutting the sprue of injection molding parts. Background Technique
[0002] The sprue (also known as the gate) of an injection molding part is an important part formed during the injection molding process. It connects the runner of the injection molding machine and the cavity of the mold, and plays a role in guiding the molten plastic into the mold cavity and filling the mold cavity. According to different shapes, structures and functions, the sprue of injection molding parts can be divided into straight sprue, annular sprue, hot runner sprue, etc.
[0003] After the injection molding is completed and the product is taken out, it is necessary to perform a cutting operation on the sprue attached to the product. At present, for the cutting operation of the sprue of such workpieces, most of them are carried out by the operator holding the injection molding part with one hand and holding the cutting machine with the other hand. However, the operator may touch the cutting knife due to improper operation, which has certain safety hazards, and the injection molding part is not fixed firmly, and it is easy to shift in position, resulting in uneven cutting edges. Therefore, a device for cutting the sprue of injection molding parts is proposed to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a device for cutting the sprue of injection molding parts to solve the problems put forward in the above background technique.
[0005] In order to solve the above technical problems, the utility model provides the following technical solution: A device for cutting the sprue of injection molding parts, including a base, a cutting mechanism is arranged on the top of the base, and a clamping mechanism is arranged on the top of the base;
[0006] The cutting mechanism includes a lower mounting frame, a first electric push rod is fixedly connected to the top of the base, the output end of the first electric push rod is fixedly connected to a top plate, an upper mounting frame is fixedly connected to the bottom of the top plate, a second electric push rod is fixedly connected to the top of the top plate, the output end of the second electric push rod is fixedly connected to a moving plate, and a cutting knife is fixedly connected to the bottom of the moving plate;
[0007] The clamping mechanism includes a support block, a threaded sleeve is rotatably penetrated through the inside of the support block, a threaded rod is threadedly connected to the inside of the threaded sleeve, and a clamping block is rotatably connected to one side of the threaded rod.
[0008] Preferably, the lower mounting frame is fixedly connected to the top of the base, and the number of the first electric push rods is two and they are symmetrically distributed on the front and rear sides of the lower mounting frame.
[0009] Preferably, the interiors of the lower mounting frame and the upper mounting frame are both designed to be hollow. Semi-circular through holes are provided on the opposite sides of the lower mounting frame and the upper mounting frame. When the output end of the first electric push rod retracts to the lowest point, the lower mounting frame and the upper mounting frame are in contact with each other.
[0010] Through the above technical solution, the hollow-designed lower mounting frame and upper mounting frame can facilitate the movement of the cutting tool inside them for the cutting process of the injection molded part's sprue. Since the stroke of the output end of the first electric push rod is equal to the distance between the lower mounting frame and the upper mounting frame, it can prevent the operator from touching the cutting tool during the sprue cutting.
[0011] Preferably, moving grooves are provided on the front and rear sides of the inner wall of the upper mounting frame, and the size of the moving grooves is adapted to the moving trajectory of the moving plate.
[0012] Through the above technical solution, the moving grooves ensure the moving direction and distance of the cutting tool, preventing the cutting tool from having a position deviation during the lifting process, which may cause the cutting edge of the injection molded part's sprue to be uneven.
[0013] Preferably, the support blocks are fixedly connected to the top of the base, and the number of the support blocks is two and they are symmetrically distributed front and back.
[0014] Preferably, a connecting ring is rotatably connected inside the support block, and the connecting ring is fixedly connected to the outer side of the threaded sleeve. When the two threaded rods move relatively to the farthest end, the opposite sides of the two clamping blocks just come into contact.
[0015] Through the above technical solution, under the connection of the connecting ring, the threaded sleeve can be rotated inside the support block, facilitating the adjustment of the position of the threaded rod inside it.
[0016] Preferably, a limiting block is fixedly connected to the bottom of the clamping block, and a limiting groove adapted to the moving trajectory of the limiting block is provided on the top of the base. The movable distance of the limiting block is equal to the movable distance of the threaded rod.
[0017] Through the above technical solution, under the joint restriction of the limiting block and the limiting groove, it can prevent the clamping block and the threaded rod from rotating together, ensuring that the clamping block can move relatively or away from each other, thereby realizing the stable clamping of the injection molded part's sprue.
[0018] Compared with the prior art, the beneficial effects achieved by the present utility model are:
[0019] First, one end of the injection molded part sprue to be cut is placed at the semi-circular through hole on the lower mounting frame. Subsequently, the first electric push rod is activated to drive the top plate to move downward until the upper mounting frame fits with the lower mounting frame. Then, the first electric push rod is turned off, and the second electric push rod is activated to drive the moving plate and the cutting knife to move downward to cut the injection molded part sprue in the two semi-circular through holes. Moreover, under the protection of the lower mounting frame and the upper mounting frame, it can prevent the staff from coming into contact with the cutting knife and causing accidents.
[0020] Second, the injection molded part sprue is placed between the two clamping blocks. By rotating the threaded sleeve, under the limitation of the limiting block and the limiting groove, the two clamping blocks move relatively or away from each other until the injection molded part sprue is fixed, which can keep the injection molded part stable during sprue cutting.
