Technical Field

[0001] The utility model relates to the technical field of injection molding machine equipment, in particular to a discharging and cleaning device for an injection molding machine. Background Technique

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold. If the injection molding machine is used for too long, a large amount of plastic and the like will remain inside, especially in the screw part. Then, the injection molding machine needs to be cleaned, otherwise, the injection work will be affected and the product quality will be reduced.

[0003] For example, in the utility model with the application number 202022660809.0, a discharging and cleaning device for an injection molding machine is disclosed. By setting a cleaning component, including a spray head slidably connected inside a kidney-shaped groove, a conduit is connected to the end of the spray head away from the U-shaped rod, the end of the conduit away from the spray head is fixedly connected to a water collecting tank, a support plate is fixed at the bottom of the water collecting tank, the support plate is fixed at the upper end of the extrusion cylinder, a water pump is fixed at the end of the conduit close to the water collecting tank, and a limiting member is arranged outside the spray head; the inside of the extrusion cylinder is rinsed through the spray head, combined with the rotation of the screw, effectively cleaning the raw material residues on the inner wall and bottom of the extrusion cylinder; at the same time, a gas-blowing component is set, including a gas spray pipe slidably connected inside the kidney-shaped groove, a connecting pipe is fixedly connected to the end of the gas spray pipe away from the kidney-shaped groove, and an air pump is fixedly connected to the end of the connecting pipe away from the gas spray pipe; the air pump is connected to the gas spray pipe, and the gas spray pipe is inserted into the through hole to conduct high-pressure air cleaning inside the extrusion cylinder, which can clean the residual raw materials. The combination of the two can achieve complete cleaning, high cleaning efficiency, and does not require too much manual operation.

[0004] The similar applications currently still have deficiencies:

[0005] This kind of discharging and cleaning device for an injection molding machine cleans the screw conveying part through a water pump and a spray head, but it is necessary to open an opening at the top of the screw conveying component to complete the cleaning work.
