Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a device for assisting the demoulding of injection molding products of an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity. Injection molding refers to various injection molding products produced by the injection molding machine, collectively referred to as injection molding, including various packages, parts, etc., which are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Injection molding is generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding and thermoforming are to shape plastics on a plane. The above methods can all be used for rubber processing, so it is necessary to use a device to assist the demoulding of injection molding products of the injection molding machine;

[0003] For example, Chinese patent CN216329727U discloses a device for assisting the demoulding of injection molding products of an injection molding machine. The device is configured by placing a first push plate inside an injection molding chamber, and installing an auxiliary screw through a threaded barrel. The auxiliary screw penetrates the injection molding chamber, and the auxiliary screw is installed inside a clamping hole. The positioning screw is rotated through the first screw hole to facilitate fixing the auxiliary screw and the first push plate, thereby realizing the disassembly and assembly of the first push plate, facilitating replacement of first push plates of different models, and conveniently pushing the injection molded parts out of the injection molding chamber through the first push plate.

[0004] However, there are certain defects in this patent. The device requires the operator to rotate the position of the positioning screw to facilitate the fixing of the auxiliary screw and the first push plate, thereby realizing the disassembly and assembly of the first push plate. The operator needs to rotate the positions of multiple positioning screws during the disassembly and assembly of the push plate, which takes a lot of time and increases the workload of the operator.
