The key technical points of this die are: it includes a base plate, with connecting columns fixedly connected to the four corners of the top of the base plate; an injection mold fixedly connected between the tops of the connecting columns; a mold top cover snapped onto the top of the injection mold; an injection tube fixedly connected to the left side of the top of the mold top cover; an electric push rod fixedly installed at the top center of the base plate; an ejector plate fixedly connected to the output end of the electric push rod; a connecting hole corresponding to the ejector plate at the bottom of the injection mold; the ejector plate inserted into the connecting hole; and a cooling coil fixedly connected to the outer surface of the injection mold. The input end of the cooling coil is connected to an external water source. The cooling coil is located on the outer surface of the injection mold and is made of a transparent, heat-resistant material. The cooling coil serves to cool the injection mold, allowing the plastic product to cool and solidify quickly.
[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the actual production process, the surface of the injection mold is easily contaminated with dust, oil and other impurities.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0023] Reference Figure 1 As shown, the present invention provides a technical solution: a plastic product molding and processing mold, including a base plate 1: a support block 6 is provided on the upper end of the base plate 1, and multiple sets of support blocks 6 are provided. An injection mold 3 is slidably connected to the upper end of the multiple sets of support blocks 6, and the injection mold 3 has a cavity inside.
[0024] Reference Figure 1 , Figure 3 and Figure 5As shown in this embodiment: The injection mold 3 has locking blocks A8 on both sides. Each set of locking blocks A8 has a locking block B81 on one side and a spring 82 on the other. A locking plate 83 is located on one side of the spring 82. A baffle 32 is engaged with one side of the locking block B81. A slot 84 is provided on one side of the baffle 32, and the locking plate 83 is engaged with the baffle 32 through the slot 84. A sliding groove 61 is provided at the upper end of each set of support blocks 6. A pulley 62 is provided at the lower end of the injection mold 3, and the pulley 62 is slidably connected within the sliding groove 61. A connecting rod A74 is provided on one side of the slider 72. A connecting rod B75 is provided at the lower end of the connecting rod A74. A mold top cover 77 is located at the lower end of the connecting rod B75. The mold top cover 77 has an internal cavity, and a water inlet 76 is provided at the upper end of the mold top cover 77. The top cover 77 has a water outlet 73 at its upper end. The bottom plate 1 is slidably connected to a water tank 2. The water tank 2 is equipped with a cool air fan 23 and a water pump 24. There are two sets of water pumps 24. One set of water pumps 24 has an inlet pipe 21 at its inlet end and an outlet pipe 22 at its outlet end. The inlet pipe 21 is connected to the mold top cover 77 through the inlet 76, and the outlet pipe 22 is connected to the mold top cover 77 through the outlet 73. Both the inlet pipe 21 and the outlet pipe 22 are made of flexible hoses and have elasticity. The top cover 77 has an injection tube 5 at its upper end. The injection mold 3 has an observation window 31 on one side. The bottom plate 1 has a support plate 4 at its upper end. The support plate 4 has a dustproof plate 41 at its upper end. The baffle 32 has a ventilation groove 33 on one side.
[0025] Working principle: The support block 6 supports the injection mold 3 and cooperates with the pulley 62 through the sliding groove 61. The pulley 62 corresponds to the sliding groove 61, which converts the sliding friction between the mold and the support block 6 into rolling friction, reducing resistance and improving disassembly efficiency, so as to realize the sliding disassembly and installation of the injection mold 3. The injection mold 3 is the core component for molding plastic products. It has a cavity inside to shape the plastic product. The spring 82 provides elastic force so that the clamping plate 83 is inserted into the clamping groove 84 of the baffle 32 to realize the longitudinal fixation of the mold. When disassembling, pressing the clamping plate 83 compresses the spring 82, so that the clamping plate 83 is disengaged from the clamping groove 84 and the fixation is released. The baffle 32 cooperates with the clamping blocks A8 and B81 to limit the lateral and longitudinal displacement of the injection mold 3. The clamping groove 84 matches the shape of the clamping plate 83 for locking and fixing. Through the sliding structure and locking design, there is no need to remove the bolts, shortening the mold replacement time. After disassembly, it can be cleaned quickly, reducing dust adhesion on the outer surface of the injection mold 3.
[0026] Reference Figures 1-4 As shown, a slide rail 7 is provided on the upper end of the base plate 1, a telescopic cylinder 71 is provided inside the slide rail 7, a slider 72 is slidably connected inside the slide rail 7, and the telescopic end of the telescopic cylinder 71 is fixedly connected to the slider 72.
[0027] Working principle: The slide rail 7 provides a sliding path for the slider 72, ensuring the linear movement of the mold top cover 77. The telescopic cylinder 71 drives the slider 72 to achieve automatic opening and closing of the mold top cover 77, replacing manual operation and improving accuracy and efficiency. The mold top cover 77 has a cavity inside, forming a coolant flow channel. The upper end is equipped with an inlet 76 and an outlet 73, which cooperate with the injection mold 3 to form a complete mold cavity. The telescopic cylinder 71 extends, pushing the slider 72 to slide along the slide rail 7. Through the connecting rod assembly, it drives the mold top cover 77 to descend and close with the injection mold 3. The injection tube 5 communicates with the mold cavity, injecting molten plastic to fill the mold cavity and complete the molding. After injection molding is completed, the telescopic cylinder 71... 1. The mold top cover 77 retracts and rises, achieving automatic opening and closing. The coolant in the cooling water tank 2 is pumped into the cavity of the mold top cover 77 through the inlet pipe 21 by a set of water pumps 24. After the coolant absorbs heat, another set of water pumps 24 pumps the hot water back to the water tank 2 through the outlet pipe 22. The cooling fan 23 cools down again, forming a closed loop. The molten plastic is injected into the mold cavity through the injection pipe 5. The operator monitors the filling status through the observation window 31 to ensure the molding quality. The dustproof plate 41 covers the top of the mold to prevent dust and debris from falling into the mold cavity and ensure product quality. The venting groove 33 discharges air from the mold cavity during the injection process to avoid bubble defects and balance the pressure inside and outside the mold cavity.
