Problems solved by technology

The problem existing in the existing injection molding machine is that after long-term use, the injection process of the injection molding machine will generate injection pressure between the front plate and the rear plate, which will cause deformation and offset of the injection part, destroy the sliding track of the moving plate, increase the In addition, the nozzle is easy to wear and tear during long-term use, which shortens the service life of the injection molding machine

Abstract

The invention discloses an injection molding machine for producing a plastic product. The injection molding machine comprises an injection part and a mold assembly part, wherein the injection part comprises a base, an L-shaped front plate, an L-shaped back plate, a pair of connecting plates, a material barrel, a movable plate and a second screw, wherein a hopper is arranged at the upper part of the material barrel; a nozzle is arranged at one end of the material barrel, and the other end of the material barrel is closed; a first screw is arranged in the material barrel; the mobile plate is provided with a pressure sensor and a nut; a sliding block with a tenon-shaped structure is arranged on the lower surface of the mobile plate; the nozzle is a cylindrical structure, and is detachably connected with a coaxial umbrella-shaped glue guiding body; the umbrella-shaped glue guiding body comprises a conical part and a cylindrical rod part; the top point of the conical part faces a mold; and a plurality of rabbets are formed in the side surface of the conical part to form a plurality of channels for molten plastic to flow. According to the injection molding machine, the displacement and deviation of the front plate and the back plate caused by injection force during injection or mold changing can be avoided, the purpose that the material barrel is not in contact with the screws is ensured, and the discharging is quick and does not damage the nozzle.

Description

technical field [0001] The invention relates to a production equipment of plastic products. More specifically, the present invention relates to an injection molding machine for producing plastic articles. Background technique [0002] Injection molding machine is a device used to produce plastic products. Typically, injection molding machines form products from polyester, vinyl acetate, different kinds of plastics, nylon, etc. in the form of melted sheets or powders and place them into molds with a predetermined shape. The injection molding machine is equipped with a mold clamping part and an injection part. When the molten plastic is discharged, the nozzle contacts the mold and maintains a state where a predetermined nozzle contact force is generated against the mold. The problem existing in the existing injection molding machine is that after long-term use, the injection process of the injection molding machine will generate injection pressure between the front plate and...
