Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine cutting device for producing injection molded parts. Background Art
[0002] After injection molding, injection molded parts, such as floor bolts, are connected by sprues between adjacent injection molded parts, and the sprues need to be cut to obtain individual injection molded part products. Currently, there are the following two methods for cutting the sprues between injection molded parts:
[0003] 1. After injection molding, the injection molded parts are clamped by a robotic arm to a conveyor belt. During the conveyance of the injection molded parts by the conveyor belt, an operator holds scissors to cut the sprue connecting the injection molded parts, resulting in high labor intensity and low efficiency.
[0004] 2. After injection molding, the injection molded parts are clamped by a robotic arm to a cutting station. The robotic arm drives the injection molded parts to move horizontally and vertically in cooperation so that the sprue of the injection molded parts moves below the cutting knife, and the cutting knife moves downward to cut the sprue. However, in this process, the robotic arm needs to drive the injection molded parts to move with many processes, long time consumption, and high precision requirements, which is not convenient to use. Summary of the Invention
[0005] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide an injection molding machine cutting device for producing injection molded parts that can improve the cutting efficiency, reduce the moving processes of the robotic arm, and is convenient to use.
[0006] To solve the above technical problem, the utility model adopts the following technical scheme:
[0007] An injection molding machine cutting device for producing injection molded parts includes a cutting table, on which at least two lifting cylinders are fixedly installed. The cylinder rods of the lifting cylinders are arranged upward and fixedly connected to a cutting seat. An installation groove is penetrated through the cutting seat. A plurality of rotating shafts are rotatably installed on the cutting seat. Both ends of the rotating shafts are located outside the cutting seat and are fixed with knife arms. The knife arms are in an inverted L shape, and the inner sides of the knife arms have cutting edges. A driving structure for driving the rotating shafts to rotate is also installed on the cutting seat.
[0008] In this way, after the robotic arm clamps the injection molded parts to the cutting station, the driving structure drives the knife arms to rotate, and the cutting edges on the inner sides of the knife arms are used to cut the sprue of the injection molded parts. After cutting, the driving structure drives the knife arms to reset, and the robotic arm clamps the injection molded parts and the sprue material for blanking.
[0009] Among them, the driving structure includes a cutting cylinder fixedly installed on one side of the cutting seat through a cylinder seat. The cylinder rod of the cutting cylinder is fixedly connected to a rack. A gear is fixed on the part of the rotating shaft located in the installation groove. The gear meshes with the rack.
[0010] Among them, arc-shaped guide rails are provided on both sides of the cutting base, a guide post is fixed to the lower end of the tool arm, and the guide post is slidably matched with the arc-shaped guide rail.
[0011] Among them, the rotating shaft is key-connected to the gear.
[0012] Among them, support crossbeams are arranged on both sides of the cutting base, and the support crossbeams and the cutting base are fixedly connected through columns.
[0013] In summary, the injection molding machine cutting device for producing injection molded parts of the present invention has the advantages of being able to improve the cutting efficiency, reducing the moving process of the robotic arm, and being convenient to use.

[0019] The present invention will be further described in detail below with reference to the drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.
[0020] Such as Figures 1-5As shown in the figure, an injection molding machine cutting device for the production of injection molded parts includes a cutting table, on which at least two lifting cylinders 2 are fixedly installed. The cylinder rods of the lifting cylinders are arranged upward and fixedly connected to a cutting seat 3. An installation groove is provided through the cutting seat. A number of rotating shafts 4 are rotatably installed on the cutting seat. Both ends of the rotating shaft are located outside the cutting seat and are fixed with knife arms 5. The knife arms are in an inverted L shape, and the inner sides of the knife arms have cutting edges. A driving structure for driving the rotating shaft to rotate is also installed on the cutting seat.
[0021] In this way, after the robotic arm clamps the injection molded part 6 to the cutting station, the driving structure drives the knife arm to rotate, and the cutting edge on the inner side of the knife arm is used to cut the sprue 7 of the injection molded part. After the cutting is completed, the driving structure drives the knife arm to reset, and the robotic arm clamps the injection molded part and the sprue material for blanking.
[0022] The knife arm is in an inverted L shape. During the cutting process, the rotation of the knife arm can achieve yielding and cutting, which can reduce the processes and precision of the robotic arm and is convenient for use.

The cylinder rod of the cutting cylinder is fixedly connected to a rack 10. A gear 11 is fixed on the part of the rotating shaft located in the installation groove. The gear meshes with the rack. The cutting cylinder drives the rack to move. The rack is located in the installation groove, and the rack is slidably fitted with the installation groove. The movement of the rack drives the gear to rotate, and the rotation of the gear drives the rotating shaft to rotate, realizing the synchronous rotation of all the knife arms. The synchronous cutting of the sprue of the injection molded part is achieved with a single power input, which is convenient for use. Specifically, the gear can adopt an incomplete gear.
[0024] During implementation, arc-shaped guide rails 12 are provided on both sides of the cutting seat. Guide columns are fixed at the lower ends of the knife arms, and the guide columns are slidably matched with the arc-shaped guide rails. It is convenient to guide the rotation of the knife arm.
