Description

Technical Field

[0001] The utility model relates to the technical field of injection molding processing, in particular to an automatic unloading device for finished injection molding products. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

[0003] After the injection molded parts are formed, the injection channel in the mold will form a connecting residual material and be taken out of the mold together with the finished product. After the injection molding is completed, the finished injection molded parts are connected to each other by the connecting residual material. At present, when removing the finished products from the connecting residual material, most of them are manually peeled off from the connecting residual material one by one. This method cannot meet the needs of automated production. At the same time, this method increases the labor intensity of workers. Therefore, we propose an automatic unloading device for finished injection molded parts to solve the above problems. Utility Model Content

When the conveyor belt transports the connection residue of the stripped injection molded part to the tail end, the connection residue is stripped off from the clamping strip through the stripping plate.

[0010] In a preferred embodiment of the utility model, the double-threaded screw is a screw with clockwise and counterclockwise threads at both ends, and the two mounting blocks are respectively installed at the clockwise and counterclockwise threads. The two mounting blocks are driven to move closer to and away from each other through the rotation of the double-threaded screw.

[0011] In a preferred embodiment of the utility model, pulleys are fixed to the output end of the driving motor and one end of the rotating shaft, and the two pulleys are connected by a V-belt, which improves the installation position of the driving motor and reduces the contact between the driving motor and the injection molded part during cutting.

Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0022] like Figure 1-5 The automatic unloading device for finished injection molded parts shown in the figure comprises a support seat 1, on which a material taking port 11 is arranged, and the inner bottom surface of the material taking port 11 is arranged to be inclined toward the outlet direction, so that the injection molded parts after stripping can slide toward the outlet direction, which is convenient for taking out the injection molded parts;

[0023] Among them, a support platen 2 is provided at the upper end of the support seat 1, a conveyor belt 3 is installed on the support platen 2, the conveyor belt 3 is driven by a built-in motor, and a feed chute 21 connected to two material taking ports 11 is provided on the support platen 2, the two feed chute 21 are respectively located on both sides of the conveyor belt 3, and a clamping strip 4 is fixed on both sides of the conveyor belt 3, and a plurality of clamping grooves 5 are provided on the clamping strip 4, the clamping strip 4 protrudes from the conveyor belt 3, and the connection surplus of the injection molded part is clamped and fixed through the clamping groove 5;

The stripping plate 8 is installed on the support seat 1 through a bracket 7, and the upper end of the stripping plate 8 is inserted between the two clamping strips 4, and the upper end of the stripping plate 8 is in contact with the conveyor belt 3. When the conveyor belt 3 transports the connection residue of the stripped injection molded part to the tail end, the connection residue is stripped off from the clamping strip 4 through the stripping plate 8;

[0025] A cutting mechanism 6 is also fixed on the support table 2. The cutting mechanism 6 includes a cylinder 61 vertically fixed on both sides of the support table 2. A crossbeam 62 is fixed between the tops of the two cylinders 61. A double-threaded screw 64 is rotatably installed inside the crossbeam 62. The double-threaded screw 64 is driven by a servo motor 63 fixed on the crossbeam 62, and both ends of the double-threaded screw 64 are threadedly connected with mounting blocks 65. The mounting blocks 65 are slidably connected to the crossbeam 62. The double-threaded screw 64 is a screw with clockwise and counterclockwise threads at both ends, and the two mounting blocks 65 are respectively installed at the clockwise and counterclockwise threads. The rotation of the double-threaded screw 64 drives the two mounting blocks 65 to move closer to or away from each other, and the height of the rear cutting wheel 69 can be adjusted by the cylinder 61.
