[0002] Injection molds are designed and manufactured with cavities of specific shapes, into which molten plastic is injected, and after cooling and solidification, it forms a product that meets the design requirements. Whether it is a simple daily necessity, such as a plastic cup or a plastic bucket, or a complex electronic component casing or automotive part, injection molds can ensure the precision and consistency of the product and meet the strict requirements of different industries for product dimensional accuracy. The existing mold consists of an upper mold, a lower mold, a cavity, a casting mechanism, a guiding and positioning mechanism, and a cooling mechanism.

[0003] Existing application number: CN202020422552.2, this utility model discloses an injection mold for an injection molding machine, including a base, a lower mold disposed above the base, an upper mold disposed above the lower mold, a top seat disposed above the upper mold, a first cavity groove formed at the upper end of the lower mold, a second cavity groove formed at the lower end of the upper mold, support rods fixedly installed between the corners of the base and the top seat, a first hydraulic cylinder fixedly installed near both sides of the upper surface of the top seat, a first telescopic rod disposed at the lower end of each of the two sets of first hydraulic cylinders, a battery disposed near the center of the upper surface of the upper mold, and an injection groove formed at the center of the upper end of the upper mold. This injection mold has excellent sealing performance, which can prevent thermoplastic from flowing into the gap between the upper and lower molds, improving the quality of the molded product, and also has a good anti-clogging effect, as well as a convenient automatic demolding function.

Traditional cleaning processes have significant technical defects: manual brushing and ultrasonic cleaning require disassembly of the mold, which is cumbersome and time-consuming. High-temperature incineration cleaning processes will reduce the surface hardness of the mold, shorten its service life, and reduce the willingness of workers to clean it. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a self-cleaning, anti-adhesion automatic injection mold. This solves the problem that after long-term use, stubborn plastic residues easily form on the surface of the cavity of existing injection molds. Traditional cleaning processes have significant technical defects: manual brushing and ultrasonic cleaning require disassembling the mold, which is cumbersome and time-consuming. High-temperature incineration cleaning processes can lead to a decrease in the surface hardness of the mold, shorten its service life, and result in low willingness among workers to clean it.

[0006] The purpose and effect of this utility model of a self-cleaning, anti-sticking automatic injection mold are achieved by the following specific technical means:

[0008] Furthermore, the self-cleaning component includes a drive cylinder and a movable plate; the drive cylinder is fixedly connected to the top rear of the support plate; the movable plate is fixedly connected to the front end of the piston rod of the drive cylinder.

[0009] Furthermore, the self-cleaning component also includes: a connecting plate and a brush; two connecting plates are provided, and the two connecting plates are respectively fixedly connected to the front of the upper and lower ends of the movable plate; two brushes are provided, and the two brushes are respectively fixedly connected to the outside of the two connecting plates.

[0010] Furthermore, the self-cleaning component also includes: connecting air pipes and nozzles; two connecting air pipes are provided, and the two connecting air pipes are separately and fixedly connected inside the movable plate; two nozzles are provided, and the two nozzles are respectively fixedly connected to the front ends of the two connecting air pipes.

[0011] Furthermore, the quick-assembly assembly includes: an operating hole and a sliding plate; the operating hole is opened inside the operating plate; the sliding plate is fixedly connected to the rear of the operating plate, and the sliding plate is slidably connected to the lower mold.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, after injection molding is completed, the upper mold is lifted to remove the workpiece. Then, the drive cylinder pushes the moving plate forward. The air pipe and nozzle connected to the air tank move forward simultaneously to blow out the cavity residue. At the same time, the connecting plate drives the brush to sweep away the adhering substances. The two work together to enhance the cleaning effect. The drive cylinder drives the moving plate to reciprocate to ensure that the entire area is clean, effectively reducing the frequency of manual cleaning and ensuring the molding effect of the injection molded workpiece.

[0015] Secondly, when changes are made to the injection molded workpiece, the operating plate is pulled through the operating hole, and the plug plate is disengaged from the limiting groove under the guidance of the sliding plate. The old cavity can then be taken out upwards, and the new cavity can be inserted. After releasing the operating plate, the connecting spring drives the plug plate to reset and lock into the cavity limiting groove, realizing tool-free quick replacement of the cavity. Compared with traditional bolt fastening, the operation efficiency is higher.

[0016] This utility model uses a drive cylinder to drive the moving plate to reciprocate, integrating air blowing and brush to clean the cavity, achieving automatic cleaning to reduce manual intervention. It adopts a spring-driven plug-in plate for quick disassembly and assembly of the cavity, allowing for tool-free cavity replacement, significantly improving production continuity and greatly increasing mold maintenance efficiency. At the same time, it effectively solves the industry pain points of time-consuming cleaning and cumbersome mold replacement in traditional processes, and is suitable for multi-variety, small-batch production scenarios.
