Description

Technical Field

[0001] This utility model relates to the field of foam mold processing technology, specifically to a foam mold production grinding device. Background Technology

[0002] Foamed mold injection products, also known as "injection-molded foamed products," are a special type of product manufactured through injection foaming technology. Their core characteristic is that the raw materials undergo a simultaneous foaming reaction during injection molding, ultimately forming a structure that is "porous internally and dense on the surface." These products combine the high efficiency and batch production capabilities of injection molding with the lightweight, cushioning, and heat insulation functions of foamed materials. They are widely used in automobiles, home appliances, and packaging. Because the volume expansion of the foamed material during molding affects the precision, surface quality, and production stability of the product, a polishing device is needed in the foamed mold production process to remove burrs from the product surface. The core structure of the existing foaming mold production and grinding device includes a frame, a positioning and clamping mechanism, a grinding execution system, and a feed control system. The frame provides stable support and works with guide rails to achieve mold movement. The positioning mechanism fixes the mold with clamps or magnetic attraction to prevent shaking during grinding.

[0003] During use, existing rotary filling machines may cause the grinding disc temperature to rise. Because foamed materials (such as EVA and PE) have low melting points (80-150℃), high-speed grinding can easily lead to surface melting and scaling, which can affect the prevention of material thermal melting and deformation, and thus affect the quality of the ground products. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the temperature of the grinding disc may rise during the use of existing rotary filling machines. Because the foaming materials (such as EVA and PE) have low melting points (80-150℃), high-speed grinding can easily lead to surface melting and scaling, which affects the prevention of material thermal melting and deformation, and affects the quality of the ground products.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A grinding device for foaming mold production includes a frame, a water tank fixed on the side wall of the frame, a water inlet on the surface of the water tank, a water pump fixed on the top of the water tank, a grinding disc rotatably connected to the inner side wall of the frame, a limiting frame fixed on the inner side wall of the frame near the grinding disc, a spray pipe inserted into the top of the limiting frame, a fan snapped onto the side wall of the limiting frame, a temperature sensor inserted into the side wall of the limiting frame near the grinding disc, a waste bin inserted into the side wall of the frame, and a filter box snapped onto the side wall of the waste bin near the bottom of the grinding disc.

[0006] The beneficial effects of this utility model are as follows: After the temperature sensor is connected to the power supply, it can detect the surface temperature of the grinding disc. When the surface temperature of the grinding disc exceeds the critical value, the grinding disc speed is reduced, and the water pump is started to draw clean water and spray it evenly onto the surface of the grinding disc through the spray pipe to cool it down. The wastewater seeping through the filter box reduces pollution. The wind generated by starting the frame accelerates the evaporation of water on the surface of the grinding disc and absorbs heat, thereby improving the cooling efficiency of the surface of the grinding disc and reducing the accumulation of water on the surface of the grinding disc, thereby improving the grinding quality of the grinding disc.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, one end of the water pump is connected to a pipe that connects to the water tank, and the other end of the water pump is connected to a pipe that connects to the top of the spray pipe. Several nozzles are inserted into the side wall of the spray pipe near the grinding disc.

[0009] Furthermore, a filter screen is snapped into the middle of the filter box, and a filter tube is inserted into the side wall of the filter box, with the other end of the filter tube connected to the water inlet.

[0010] Furthermore, a mounting base is fixed on the inner side wall of the waste bin, a groove is provided in the middle of the mounting base for the filter box to be snapped in, and a slot is provided on the side wall of the waste bin for the filter screen to be installed.

[0011] Furthermore, a PLC controller is installed on the side wall of the rack, and the water pump, fan, and temperature sensor are coupled to the PLC controller.

[0012] Furthermore, two first guide rails are fixed on the inner side wall of the frame, and a second guide rail is movably connected between the two first guide rails. A slider is slidably connected to the outer surface of the second guide rail, and a tray is rotatably connected to the top of the slider.

[0013] Furthermore, a gantry frame is fixed at the top of the second guide rail, an electric actuator is fixed at the top of the gantry frame, and a support block is fixed at the output end of the electric actuator. The support block and the slider are located in the same vertical direction.

[0014] Furthermore, a cover plate is rotatably connected to the bottom of the support block, and anti-slip grooves are provided on both the surface of the tray and the bottom of the cover plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the stability of the filter box installation is improved by cooperating with the mounting base and the filter box; the wastewater seeping from the surface of the grinding disc is received by the filter box, the wastewater is initially filtered by the filter screen and then filtered a second time by the filter pipe, and then discharged into the internal water tank for recycling, thereby reducing water waste.

[0019] like Figure 1-5As shown, the foaming mold production and grinding device includes a frame 1. A water tank 2 is bolted to the side wall of the frame 1. The water tank 2 is used to store clean water. A water inlet 16 is opened on the surface of the water tank 2 for adding clean water. A water pump 3 is bolted to the top of the water tank 2. The water pump 3 is the core mechanical structure for conveying and pressurizing liquid, including an impeller, pump casing, and drive motor to drive the water flow. One end of the water pump 3 is connected to a pipe connected to the water tank 2 for water intake. The inner side wall of the frame 1 is rotatably connected to... The grinding disc 4 is driven by a motor to rotate at high speed. When the grinding disc 4 rotates at high speed, it comes into contact with the product produced by the foaming mold to achieve grinding. A limiting frame 5 is fixed on the inner wall of the frame 1 near the grinding disc 4. A spray pipe 10 is inserted into the top of the limiting frame 5. The other end of the water pump 3 is connected to a pipe that is connected to the top of the spray pipe 10. Several nozzles are inserted into the side wall of the spray pipe 10 near the grinding disc 4. A fan 11 is clamped on the side wall of the limiting frame 5. A temperature sensor 17 is inserted into the side wall near the grinding disc 4, and a PLC controller is installed on the side wall of the frame 1. The water pump 3, fan 11, and temperature sensor 17 are coupled to the PLC controller, which improves the control accuracy of the device. The end of the temperature sensor 17 passes through the limit frame 5 and faces the grinding disc 4 to detect the surface temperature of the grinding disc 4. A waste bin 12 is inserted into the side wall of the frame 1, and a filter box 13 is clipped onto the side wall of the waste bin 12 near the bottom of the grinding disc 4. When the temperature sensor 17 detects that the surface temperature of the grinding disc 4 has risen, the water pump 3 can be started to draw clean water from the water tank 2 and spray it evenly onto the surface of the grinding disc 4 through the spray pipe 10. The water seeping down from the surface of the grinding disc 4 is received by the filter box 13, thereby avoiding contamination inside the frame 1. Then, the frame 1 is started to generate wind to accelerate the evaporation of water on the surface of the grinding disc 4 and absorb heat, thereby improving the cooling efficiency of the surface of the grinding disc 4 and reducing the accumulation of water mist on the grinding disc 4, thereby improving the grinding quality of the foam mold products.

[0020] like Figure 2-4 As shown, a filter screen 14 is snapped into the middle of the filter box 13 for preliminary filtration of wastewater. A filter tube 15 is inserted into the side wall of the filter box 13. A filter element is installed in the middle of the filter tube 15 for secondary filtration. The other end of the filter tube 15 is connected to the water inlet 16, which facilitates wastewater recycling and reduces resource waste.

[0021] like Figure 4 As shown, a mounting base 18 is fixed on the inner side wall of the waste bin 12. A groove is provided in the middle of the mounting base 18 for the filter box 13 to be engaged. A slot is provided on the side wall of the waste bin 12 for the filter screen 14 to be installed, which improves the stability of the filter box 13 installation.

[0022] like Figure 1-5As shown, two first guide rails 6 are fixed on the inner side wall of the frame 1. A second guide rail 7 is movably connected between the two first guide rails 6. A slider 8 is slidably connected to the outer surface of the second guide rail 7. A tray 9 is rotatably connected to the top of the slider 8. A gantry frame 19 is fixed to the top of the second guide rail 7. An electric push rod 20 is fixed to the top of the gantry frame 19. A support block 21 is fixed to the output end of the electric push rod 20. The support block 21 and the slider 8 are located in the same vertical direction. A cover plate 22 is rotatably connected to the bottom end of the support block 21. Anti-slip grooves are provided on the surface of the tray 9 and the bottom end of the cover plate 22.

[0023] Working principle: When using this foaming mold production grinding device, the operator first connects the external power supply, then places the foamed product to be processed on the top of the tray 9, starts the water tank 2 to push the support block 21 to move vertically downward so that the cover plate 22 and the tray 9 clamp the product, starts the first guide rail 6 and the second guide rail 7 and adjusts the distance between the tray 9 and the grinding disc 4, starts the tray 9 to adjust the angle between the product and the grinding disc 4, thereby achieving all-round grinding. The debris generated by grinding falls into the waste bin 12. When the temperature sensor 17 detects that the surface temperature of the grinding disc 4 has risen, the water pump 3 can be started to draw clean water from the water tank 2 and spray it evenly onto the surface of the grinding disc 4 through the spray pipe 10. The water seeping down the surface of the grinding disc 4 is received through the filter box 13, thereby avoiding contamination inside the frame 1. Then the frame 1 is started to generate wind to accelerate the evaporation of water on the surface of the grinding disc 4 and absorb heat, thereby improving the cooling efficiency of the surface of the grinding disc 4 and reducing the accumulation of water mist on the grinding disc 4, thereby improving the grinding quality of the foaming mold product.

[0024] Secondly, the installation stability of the filter box 13 is improved by the cooperation of the mounting base 18 and the filter box 13. The filter box 13 is used to receive the wastewater seeping from the surface of the grinding disc 4. After being initially filtered by the filter screen 14, it is then filtered a second time by the filter tube 15 and then discharged into the water tank 2 for recycling, thereby reducing water waste.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
