Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine for wastewater treatment plastic components with a flame retardant dispersion and guiding structure. Background Technology

[0002] Wastewater treatment plastic components (pipe fittings) require excellent flame retardant properties to meet safety requirements under complex operating conditions due to prolonged contact with wastewater media. These components typically achieve flame retardancy by adding flame retardants to the plastic raw material. However, existing injection molding machines use only a single screw to mix the raw material containing flame retardants. Therefore, the flame retardant in the raw material may agglomerate due to density differences or viscosity characteristics. This can lead to excessively high or low concentrations of flame retardant in localized areas of the molded plastic component, affecting the overall stability of its flame retardant performance and potentially causing internal stress concentration or surface defects.

[0003] Moreover, traditional injection molding machines have low barrel temperature control precision, and the injection molding raw materials may experience changes in the surface tension of the flame retardant due to sudden temperature changes, leading to problems such as agglomeration, sedimentation, or aggregation of the raw materials. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an injection molding machine for wastewater treatment plastic components with a flame retardant dispersion and flow guiding structure, thereby solving the problems of uneven flame retardant dispersion, unreasonable melt flow guiding, poor synergy between dispersion and injection molding, and insufficient high-temperature stability in the production of wastewater treatment plastic components containing flame retardants by existing injection molding machines.

[0005] This utility model also provides a wastewater treatment plastic component injection molding machine with the aforementioned flame retardant dispersion and guiding structure, comprising: a frame, a fixing plate fixedly connected to the upper surface of the frame, a first motor fixedly connected to the side of the fixing plate, a support plate fixedly connected to the upper surface of the frame, an injection box fixedly connected inside the support plate, a screw rotatably connected inside the injection box, the output end of the first motor fixedly connected to one end of the screw, a feed pipe fixedly connected to the outer surface of the injection box, and helical teeth fixedly connected to the surface of the screw. The helical teeth are arranged in four sets, distributed in a spiral shape, and located at positions corresponding to the feed pipe inside the injection box. This effectively breaks up agglomerated flame retardant particles in the injection molding raw material, enabling the flame retardant to form a uniformly dispersed system in the raw material melt, thus solving the problem of insufficient dispersion in traditional injection molding machines.

The spiral teeth form a pre-dispersion chamber with the injection molding box during rotation, and the surface of the spiral teeth is provided with several grooves. This is used to effectively shear and disperse agglomerated particles of flame retardant in the injection molding raw material.

This is used for premixing injection molding raw materials.

[0009] According to the present invention, a wastewater treatment plastic component injection molding machine with a flame retardant dispersion and guiding structure is provided. A feed inlet is fixedly connected to the upper surface of the injection barrel, and a second motor is fixedly connected to the upper surface of the injection barrel. This motor is used for inputting and mixing the injection molding raw materials.

This is used to pre-mix the injection molding raw materials.

[0011] According to the present invention, a wastewater treatment plastic component injection molding machine with a flame retardant dispersion and guiding structure is provided. The inner wall of the injection barrel is provided with a guiding groove, which is spiral in shape. A constant temperature heating jacket is fixedly connected to the outer surface of the injection barrel, and a temperature sensor is fixedly connected to the inner surface of the constant temperature heating jacket. This is used to improve the dispersion and uniformity of the flame retardant in the injection molding raw material within the resin.

[0012] According to the present invention, a wastewater treatment plastic component injection molding machine with a flame retardant dispersion and guiding structure is provided. An injection port is provided at the end of the injection box away from the first motor, and a finished product box is provided at the lower end of the injection port. This is used to complete the injection molding process of the raw material.

[0013] Beneficial effects:

[0014] This technical solution for a wastewater treatment plastic component injection molding machine with a flame retardant dispersion and flow guiding structure effectively breaks down agglomerated flame retardant particles in the injection molding raw material by forming a pre-dispersion chamber with four sets of spiral teeth inside the injection barrel. Utilizing the shearing and dispersing action of the internal spiral dispersion teeth, the flame retardant forms a uniform dispersion system within the melt, effectively addressing the problem of insufficient dispersion in traditional injection molding machines. Furthermore, by installing a constant-temperature heating jacket and temperature sensor on the outer surface of the injection barrel, the thermal stability of the flame retardant is maintained as much as possible without entering the high-temperature injection zone, mitigating the risk of early degradation and preventing agglomeration, sedimentation, or aggregation caused by temperature fluctuations. This reduces changes in the surface tension of the flame retardant due to sudden temperature changes, thereby improving particle dispersion in the resin matrix and enhancing dispersion uniformity. Ultimately, this reduces the impact of melt viscosity fluctuations on injection molding. Attached Figure Description

The machine includes: a frame 1, a device for fixing and supporting the injection molding equipment; a fixing plate 2 fixedly connected to the upper surface of the frame 1 for fixing and supporting a first motor 4; the first motor 4 fixedly connected to the side of the fixing plate 2 for driving a screw 41, spiral teeth 42, and spiral stirring blades 43 to rotate and stir, effectively breaking up agglomerated flame retardant particles in the injection molding raw material, and forming a uniformly dispersed system of flame retardant in the raw material melt; a support plate 3 fixedly connected to the upper surface of the frame 1 for fixing an injection molding box 7; and an injection molding box 7 fixedly connected inside the support plate 3 for loading the injection molding raw material into a finished product. The injection molding box 7 is rotatably connected to a screw 41. The output end of the first motor 4 is fixedly connected to one end of the screw 41 to facilitate stirring of the injection molding material. The outer surface of the injection molding box 7 is fixedly connected to a discharge pipe 11, so that the injection molding material after mixing is discharged into the injection molding box 7 for the next process. The surface of the screw 41 is fixedly connected to a spiral tooth 42. There are four sets of spiral teeth 42, which are distributed in a spiral shape to form an effective pre-dispersion cavity when rotating. This helps to shear and disperse the flame retardant agglomerates in the injection molding material and avoid agglomeration due to density differences or viscosity characteristics. The spiral teeth 42 are located at the corresponding positions of the discharge pipe 11 inside the injection molding box 7 to form the pre-dispersion cavity.

[0025] Specifically, a spiral stirring blade 43 is fixedly connected to the surface of the screw 41. The spiral stirring blade 43 is located two-thirds of the way inside the injection molding box 7, and is used to convey the mixed injection molding material to the injection port 71, and to complete the injection molding process. The spiral teeth 42 form a pre-dispersion chamber with the injection molding box 7 during rotation. The surface of the spiral teeth 42 is provided with several grooves to effectively shear and disperse the flame retardant agglomerates in the injection molding material, ensuring the stability of the flame retardant performance of the molded plastic components. A support frame is fixedly connected to the rear surface of the frame 1, and an injection cylinder 6 is fixedly connected to the upper surface of the support frame for pre-mixing the injection molding material, laying the foundation for subsequent shearing and dispersion of the injection molding material and reducing the mixing time in the injection molding box 7. A feed port 9 is fixedly connected to the upper surface of the injection cylinder 6, and a second motor 5 is fixedly connected to the upper surface of the injection cylinder 6 for injecting the injection molding material... The second motor 5 is fixedly connected to a rotating rod 51 at its output end for input and mixing. A stirring blade 52 is fixedly connected to the surface of the rotating rod 51 to pre-mix the injection molding material. A spiral-shaped guide groove 61 is formed on the inner wall of the injection barrel 6. A constant-temperature heating jacket 8 is fixedly connected to the outer surface of the injection barrel 6, and a temperature sensor 10 is fixedly connected to the inner surface of the constant-temperature heating jacket 8. This improves the dispersion and uniformity of the flame retardant in the resin, controls the resin viscosity and processing stability, improves the molding quality of its guiding structure, and reduces the risk of thermal degradation and flame retardant failure. An injection port 71 is located at the end of the injection box 7 furthest from the first motor 4. A finished product box 12 is located at the lower end of the injection port 71 to complete the injection molding process of the injection molding material.

[0026] Working principle: When using the injection molding machine for wastewater treatment plastic components with this flame retardant dispersion and flow guiding structure, the injection raw material enters the injection barrel 6 from the feed port 9. The second motor 5 drives the rotating rod 51 and the stirring blade 52 to rotate and stir. After stirring, the raw material enters the injection box 7 from the discharge pipe 11. Then, the raw material in the injection box 7 is squeezed out from the injection port 71 by the first motor 4 driving the screw 41, the spiral teeth 42 and the spiral stirring blade 43 to rotate, thus completing the injection molding process.
