Description

Technical Field

[0001] The utility model relates to the technical field of mold processing cooling, in particular to a cooling device for processing injection mold parts. Background Technique

[0002] Injection molding is a conventional method for mass-producing parts with complex shapes. The cooling and molding of molten plastic in an injection mold rely on the cooling structure in the mold. However, the cooling structure in the mold cools the parts from the outside to the inside, which results in a still relatively high temperature inside the injection-molded parts after initial molding or incomplete cooling and molding inside. If only relying on the cooling structure in the mold to completely cool the parts, it will take a lot of time, leading to low efficiency in producing parts by the injection mold. Therefore, after the parts are initially cooled and molded, they need to be taken out and a special cooling device is used to perform subsequent complete cooling.

[0003] Currently, the commonly used cooling devices for processing injection mold parts only cool the parts by air-cooling means. The internal heat is dissipated to the outer layer and then the surface heat is carried away by air flow. However, due to the material reasons of the injection-molded parts, the heat conduction efficiency is low. Therefore, the conduction speed of the internal heat to the outer layer is slow, resulting in a slow cooling speed and low cooling efficiency.

[0004] For this reason, a cooling device for processing injection mold parts is proposed. Content of the Utility Model

[0005] The purpose of the utility model is: to solve the problems mentioned in the above background technique, the utility model provides a cooling device for processing injection mold parts.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A cooling device for processing injection mold parts, including a cooling box. Support legs are fixedly installed at the four corners of the bottom surface of the cooling box. A triangular turnover mechanism is arranged between the front and rear side walls of the cooling box. A loading mechanism is fixedly installed on the surface of the triangular turnover mechanism. The number of the loading mechanisms is three and they are evenly distributed around the triangular turnover mechanism. A water body inlet and outlet assembly is arranged on the side wall and the bottom wall of the cooling box. A pressure sensor is fixedly installed on the side surface of the inner wall of the cooling box. A temperature sensor is fixedly installed on the bottom surface of the inner wall of the cooling box. A material taking opening is formed in the middle of the top wall of the cooling box. A blowing cover plate assembly for covering the material taking opening is arranged on the top surface of the cooling box. Side fans are fixedly installed on both the left and right side walls of the cooling box. The side fans are arranged above the pressure sensor, and the pressure sensor is arranged above the water body inlet and outlet assembly.

[0008] Further, the triangular turnover mechanism includes a motor, which is fixedly installed on the outer surface of the cooling box. The output end of the motor is fixedly connected to a main rotating shaft, which is rotatably installed between the front and rear side walls of the cooling box. Both the front and rear ends of the side surface of the main rotating shaft are fixedly installed with mounting plates. The number of the mounting plates is six, with three arranged in the front and three in the rear. The three mounting plates on one side are distributed in a Y shape on the side surface of the main rotating shaft. The relative surfaces of the two front and rear opposite mounting plates are rotatably installed with mounting shafts. The mounting shafts are arranged at one end of the mounting plate surface far from the main rotating shaft. The loading mechanism is fixedly installed between the two front and rear opposite mounting shafts.

[0009] Further, the loading mechanism includes a loading box, which is fixedly installed between the two front and rear opposite mounting shafts. A counterweight block is fixedly installed on the bottom surface of the loading box. One side of the top surface of the loading box is hinged with a protective cover. A buckle for fixing the protective cover is arranged on the surface of the loading box. A plurality of leakage holes are opened on the surfaces of the loading box, the counterweight block and the protective cover, and the leakage holes are evenly distributed.

[0010] Further, the loading box is of a hopper-shaped structure, and the leakage holes opened on the surface of the counterweight block coincide with the leakage holes opened on the bottom surface of the loading box.

[0011] Further, the water body inlet and outlet assembly includes a liquid inlet pipe and a liquid discharge pipe. The liquid inlet pipe is fixedly inserted into the side wall of the cooling box. The liquid inlet pipe is arranged below the pressure sensor. A liquid inlet solenoid valve is arranged on the surface of the liquid inlet pipe. The liquid discharge pipe is fixedly inserted into the bottom wall of the cooling box. A liquid discharge solenoid valve is arranged on the surface of the liquid discharge pipe.

[0012] Further, the air blowing cover plate assembly includes a limit slide rail and a sliding cover. The limit slide rail is fixedly installed on the top surface of the cooling box. The sliding cover is slidably arranged in contact with the top surface of the cooling box. The sliding cover is slidably installed on the inner wall surface of the limit slide rail. The specification of the sliding cover is slightly larger than the specification of the material taking port. A top fan is fixedly installed on the top surface of the sliding cover. A handle is fixedly installed on the top surface of the sliding cover.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Water is injected into the cooling box through the water body inlet and outlet assembly. The two loading mechanisms below are immersed in the water body to perform water cooling on the parts in the two lower loading mechanisms. Through the side fans and the air blowing cover plate assembly located above the water body, air is blown from both sides and the top of the upper loading mechanism. While further air cooling, air drying is carried out. It is possible to perform sequential immersion water cooling, air cooling and drying on the parts in different loading mechanisms batch by batch. Compared with single air cooling, it has a more efficient cooling effect, reduces the cooling time, and thus improves the processing efficiency of the parts produced by the injection mold.

[0015] 2. A pressure sensor is used to sense the pressure generated when the water body contacts it. When the water level reaches the surface of the pressure sensor, a signal is sent to the external controller to interrupt the water inlet operation of the water body inlet and outlet component, ensuring that the loading mechanism above does not contact the water body and the side fan is not damaged by being submerged in the water body, realizing the functional partition of water cooling and air cooling drying. By rotating and stopping the triangular turnover mechanism, the loading mechanism can be coherently adjusted to move between different functional areas. Brief Description of the Drawings

[0025] As Figures 1 to 3 shown, an injection mold part processing cooling device includes a cooling box 1. Support legs 2 are fixedly installed at the four corners of the bottom surface of the cooling box 1. A triangular turnover mechanism 3 is provided between the front and rear side walls of the cooling box 1. A loading mechanism 4 is fixedly installed on the surface of the triangular turnover mechanism 3. The number of loading mechanisms 4 is three and they are evenly distributed around the triangular turnover mechanism 3. A water body inlet and outlet assembly 5 is provided on the side wall and bottom wall of the cooling box 1. A pressure sensor 6 is fixedly installed on the inner side surface of the inner wall of the cooling box 1. A temperature sensor 7 is fixedly installed on the bottom surface of the inner wall of the cooling box 1. A material taking opening 8 is formed in the middle of the top wall of the cooling box 1. A blowing cover plate assembly 9 for covering the material taking opening 8 is provided on the top surface of the cooling box 1. Side fans 10 are fixedly installed on both the left and right side walls of the cooling box 1. The side fans 10 are arranged above the pressure sensor 6, and the pressure sensor 6 is arranged above the water body inlet and outlet assembly 5.

[0026] More specifically, the parts produced by the injection mold are loaded in batches through three loading mechanisms 4, water is injected into the cooling box 1 through the water inlet and outlet assembly 5, and the two loading mechanisms 4 below are immersed in water to water-cool the parts in the two loading mechanisms 4 below. The pressure sensor 6 is used to sense the pressure generated when the water contacts it, and when the water level reaches the surface of the pressure sensor 6, a signal is sent to the controller of the external device to interrupt the water inlet operation of the water inlet and outlet assembly 5 to ensure that the upper loading mechanism 4 will not contact the water and the side fan 10 will not be immersed in the water and damaged, thereby realizing the functional zoning of water cooling and air cooling and drying. The loading mechanism 4 can be continuously adjusted to move between different functional areas through the rotation and stop of the triangular turnover mechanism 3, and the temperature sensor is used to sense the pressure generated when the water contacts it. 7. Monitor the water temperature. When the water temperature exceeds a certain value, the water inlet and outlet assembly 5 is controlled by an external control mechanism to discharge the high-temperature water and re-inject the low-temperature water into the low-temperature water to ensure a good water-cooling heat absorption effect. The side fans 10 and the blast cover assembly 9 located above the water are used to blow air from both sides and the top of the upper loading mechanism 4 to further cool and dry the parts. After the parts in the upper loading mechanism 4 are fully cooled and dried, the blast cover assembly 9 can be opened to take out the parts in the loading mechanism 4. It can be achieved that the parts in different loading mechanisms 4 are immersed in water first and then cooled and dried by air in batches. Compared with single air cooling, it has a more efficient cooling effect, reduces cooling time, and thus improves the processing efficiency of parts produced by injection molds.

[0027] The triangular rotating mechanism 3 includes a motor 301, which is fixedly installed on the outer surface of the cooling box 1. The output end of the motor 301 is fixedly connected to the main rotating shaft 302, and the main rotating shaft 302 is rotatably installed between the front and rear side walls of the cooling box 1. The front and rear ends of the side of the main rotating shaft 302 are fixedly installed with mounting plates 303. The number of the mounting plates 303 is six, and three are arranged at the front and back. The three mounting plates 303 on a single side are distributed in a Y shape on the side of the main rotating shaft 302. The relative surfaces of the two front and rear opposite mounting plates 303 are rotatably installed with mounting shafts 304. The mounting shaft 304 is arranged at one end of the surface of the mounting plate 303 away from the main rotating shaft 302, and the loading mechanism 4 is fixedly installed between the two front and rear opposite mounting shafts 304.

[0028] Specifically, the output end of the motor 301 drives the main rotating shaft 302 to rotate, and the main rotating shaft 302 drives the mounting plate 303 fixedly mounted on its surface to rotate around the axis of the main rotating shaft 302, and finally drives the loading mechanism 4 fixedly mounted on the surface of the mounting shaft 304 to rotate around the axis of the main rotating shaft 302, and then adjusts the positions of the three loading mechanisms 4, so that different loading mechanisms 4 are immersed in the water in turn and then moved to the top, so that the parts in the loading mechanism 4 are first immersed in water and cooled, and then air-cooled and dried by the side fan 10 and the blower cover assembly 9.

[0029] The loading mechanism 4 includes a loading box 401, which is fixedly installed between two relatively front and rear mounting shafts 304. A counterweight 402 is fixedly installed on the bottom surface of the loading box 401. One side of the top surface of the loading box 401 is hinged with a protective cover 403. The surface of the loading box 401 is provided with a buckle 404 for fixing the protective cover 403. The surfaces of the loading box 401, the counterweight 402, and the protective cover 403 are all provided with leakage holes 405, and the number of the leakage holes 405 is several and they are evenly distributed.

[0030] Specifically, the counterweight 402 is used to balance the overall loading mechanism 4 and the parts loaded inside it, so that the overall center of gravity remains in the middle. Furthermore, when the loading mechanism 4 rotates, it can drive the mounting shaft 304 to rotate, so that the loading mechanism 4 itself can maintain a horizontal state to the greatest extent. Especially after the loading mechanism 4 rotates to the upper part, the horizontal loading mechanism 4 makes it convenient to take the parts inside it. At this time, disconnect the fixing of the buckle 404 to the protective cover 403, then the protective cover 403 can be rotated and opened, and then the parts in the loading box 401 can be taken out. By setting the leakage holes 405, water and air can easily enter the inside of the loading box 401 to cool, air-cool and dry the parts in the loading box 401, and when the loading mechanism 4 moves to the upper part, it ensures that the water inside it can quickly leak out.

[0031] The loading box 401 is of a hopper-shaped structure, and the leakage holes 405 formed on the surface of the counterweight 402 coincide with the leakage holes 405 formed on the bottom surface of the loading box 401.

[0032] Specifically, the loading box 401 is of a hopper-shaped setting, so that the parts loaded in the loading box 401 are concentrated in the middle. Cooperating with the counterweight 402, it further ensures that the overall center of gravity of the loading mechanism 4 remains in the middle. By setting the leakage holes 405 on the surface of the counterweight 402 to coincide with the leakage holes 405 on the bottom surface of the loading box 401, the entry and exit of water and the flow of air are more smooth and unobstructed, thereby accelerating the cooling and drying efficiency.

[0033] The water body inlet and outlet assembly 5 includes a liquid inlet pipe 501 and a liquid discharge pipe 503. The liquid inlet pipe 501 is fixedly inserted into the side wall of the cooling box 1. The liquid inlet pipe 501 is arranged below the pressure sensor 6. The surface of the liquid inlet pipe 501 is provided with a liquid inlet solenoid valve 502. The liquid discharge pipe 503 is fixedly inserted into the bottom wall of the cooling box 1. The surface of the liquid discharge pipe 503 is provided with a liquid discharge solenoid valve 504.

[0034] Specifically, a low-temperature water body is injected into the cooling tank 1 through the liquid inlet pipe 501. When the water body contacts the surface of the pressure sensor 6, the pressure sensor 6 senses the pressure and sends a signal to an external controller. The external controller controls the liquid inlet solenoid valve 502 to close, so that the water body can no longer enter the interior of the cooling tank 1 through the liquid inlet pipe 501. At this time, the two loading mechanisms 4 below are immersed, while the loading mechanism 4 above is blown by the air blowing cover assembly 9 and the side fan 10. The temperature of the water body is sensed by the temperature sensor 7. When the temperature of the water body gradually rises to a certain value due to absorbing the heat of the parts, its cooling effect is poor. At this time, the external controller controls the drain solenoid valve 504 to open, so that the water body in the cooling tank 1 is discharged through the drain pipe 503, and then the liquid inlet solenoid valve 502 is opened to re-inject the low-temperature water body through the liquid inlet pipe 501 to ensure the water cooling efficiency.

[0035] The air blowing cover assembly 9 includes a limit slide rail 901 and a sliding cover 902. The limit slide rail 901 is fixedly installed on the top surface of the cooling tank 1. The sliding cover 902 is slidably arranged in contact with the top surface of the cooling tank 1. The sliding cover 902 is slidably installed on the inner wall surface of the limit slide rail 901. The specification of the sliding cover 902 is set slightly larger than the specification of the material taking port 8. A top fan 903 is fixedly installed on the top surface of the sliding cover 902, and a handle 904 is fixedly installed on the top surface of the sliding cover 902.

[0036] Specifically, when it is necessary to air-cool and dry the parts in the upper loading mechanism 4, the sliding cover 902 is located directly above the material taking port 8. At this time, the sliding cover 902 is directly above the upper loading mechanism 4. The top fan 903 and the side fan 10 work simultaneously to blow the upper loading mechanism 4 from both sides and the top to achieve further air-cooling and drying. After the air-cooling and drying are completed, by grasping and pulling the handle 904, the sliding cover 902 is driven to slide along the inner wall surface of the limit slide rail 901, so that the sliding cover 902 slides away from above the material taking port 8 to the top surface of the cooling tank 1, exposing the material taking port 8. At this time, the upper loading mechanism 4 can be opened and the parts inside can be taken out.

[0037] In summary: Water is injected into the cooling tank 1 through the water inlet and outlet component 5, and the two loading mechanisms 4 below are submerged by the water body to perform water cooling on the parts in the two loading mechanisms 4 below. Through the side fan 10 and the air blowing cover plate assembly 9 located above the water body, air is blown to the loading mechanism 4 above from both sides and the top. While further air cooling, air drying is also carried out. It is possible to perform submersible water cooling, then air cooling and drying on the parts in different loading mechanisms 4 batch by batch. Compared with single air cooling, it has a more efficient cooling effect, reduces the cooling time, and thus improves the processing efficiency of the parts produced by the injection mold. The pressure sensor 6 is used to sense the pressure generated when the water body contacts it. When the water level reaches the surface of the pressure sensor 6, a signal is sent to the external controller to interrupt the water inlet operation of the water inlet and outlet component 5, ensuring that the loading mechanism 4 above does not contact the water body and the side fan 10 is not submerged by the water body and damaged, realizing the functional partition of water cooling and air cooling and drying. Through the rotation and stop of the triangular turnover mechanism 3, the movement of the loading mechanism 4 between different functional areas can be coherently adjusted.
