Description

Technical Field

[0001] The utility model relates to the technical field of injection molding assembly, in particular to an assembly device for injection molding assembly. Background Art

[0002] Injection molded parts refer to various injection products produced by injection molding machines, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. The choice of plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Injection molded parts are generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding and thermoforming are to shape plastics on a plane. After the injection molded parts are formed, they need to be assisted by a special assembly device.

[0003] The existing patent technology CN202223603993.0 proposes that safety accidents can be prevented by placing the injection molded parts to be assembled in the mounting grooves of the mounting blocks. However, there are various specifications of the injection molded parts to be assembled, and frequent replacement of the mounting blocks leads to low assembly efficiency. Based on this, an injection molded parts assembly device is proposed. According to the specifications of the injection molded parts to be assembled, the receiving turntable and the moving turntable can be rotated to select two corresponding mounting blocks, and the cylinder output shaft is extended to drive the injection molded part to be assembled to move, and the positioning groove of the injection molded part to be assembled is inserted into the positioning groove of the injection molded part to be assembled.

[0004] When the injection molding assembly device is working, the cylinder output shaft extends, driving the injection molding part to be assembled to move, and the positioning column of the injection molding part to be assembled is inserted into the positioning groove of the injection molding part to be assembled. Although it can replace manual work to assemble the injection molding parts, the types of fixtures assembled thereon are still limited. When the fixture needs to be replaced, the operation is more cumbersome. In addition, during the assembly process of the injection molding parts, the injection molding parts and the fixtures are completely matched, which is not convenient for placing the injection molding parts. For this reason, we designed an assembly device for injection molding parts to solve the above problems. Utility Model Content

[0025] The movable seats 3 and the fixed seats 4 are movablely sleeved on the inner sides with evenly distributed movable plates 8, and the movable seats 3 and the fixed seats 4 are sleeved on the inner sides with bidirectional threaded rods 6 threadedly connected to the movable plates 8, the movable seats 3 and the fixed seats 4 are provided with cavities matching the movable plates 8 on the inner sides, the cavities on the inner sides of the movable seats 3 and the fixed seats 4 can facilitate the movement of the movable plates 8, and the movable seats 3 and the fixed seats 4 are provided with openings matching the movable plates 8 on the outer sides, and the openings on the outer sides of the movable seats 3 and the fixed seats 4 can facilitate the movable plates 8 to drive the socket seats 7, the plug seats 9, and the injection molding fixture 10 to move.

[0026] One end of the movable plate 8 extends to the outside of the movable seat 3 and the fixed seat 4 and is fixedly connected with the socket seat 7. The two movable plates 8 form a group. The two-way threaded rod 6 is provided with two groups of threads in opposite directions. When the servo motor 5 is working, it can drive the rotating rod 12 to rotate as a whole through its driving shaft, and then drive the two-way threaded rod 6 to rotate. The two movable plates 8 in the same group are symmetrically distributed on the outside of the two-way threads of the two-way threaded rod 6. The movable plate 8 is pushed to slide in the movable seat 3 and the fixed seat 4 through the threads on the outside of the two-way threaded rod 6, and indirectly drives the injection molding fixture 10 to move following the movement of the socket seat 7 and the movable plate 8.
