Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, and specifically relates to a die casting mold with a circulating cooling structure. Background Technology

[0002] In modern manufacturing, die-casting molds are key tools for producing metal parts, widely used in the automotive, aerospace, and electronics industries. Temperature control of the mold is crucial during the die-casting process, as excessively high mold temperatures can lead to part deformation, decreased surface quality, and even impact production efficiency and product quality. Traditional die-casting mold cooling methods typically employ simple water cooling systems.

[0003] Traditional water-cooling systems typically employ simple straight-pipe structures, resulting in a short flow path for the coolant within the mold and insufficient contact with the mold surface, leading to low cooling efficiency. Therefore, we need to propose a die-casting mold with a circulating cooling structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a die-casting mold with a circulating cooling structure. By setting up a cooling component, the cooling pipe cools the die-casting mold when the die-casting mold is producing die-cast parts. The coolant flows in an S-shaped structure inside the mold, which increases the contact area between the coolant and the mold surface, thereby achieving the cooling of the mold and significantly improving the cooling efficiency. This allows the die-cast parts to be cooled quickly, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a die-casting mold with a circulating cooling structure, comprising a base plate, a lower mold mounted on the base plate, an mounting frame mounted on the base plate, an upper mold mounted on the mounting frame, a lifting assembly for driving the upper mold to move vertically mounted on the mounting frame, a cooling assembly for cooling the lower mold mounted on the base plate, and a filtering assembly for filtering the coolant mounted on the cooling assembly;

[0006] The cooling assembly includes an external cooling mechanism and a cooling pipe. The external cooling mechanism is mounted on the base plate, and the cooling pipe is installed inside the lower mold. The cooling pipe has an S-shaped structure, with both ends extending through to both sides of the lower mold. Both ends of the cooling pipe are connected to the external cooling mechanism.

[0007] Furthermore, the external cooling mechanism includes a cooling box mounted on a base plate. A transfer pump is installed at one end of the cooling box, and a first transfer pipe is installed on the transfer pump. One end of the first transfer pipe is connected to one end of the cooling pipe. A second transfer pipe is installed at the other end of the cooling box, and one end of the second transfer pipe is connected to the other end of the cooling pipe.

[0008] Furthermore, the cooling box contains coolant, a semiconductor cooling chip is installed on one inner wall of the cooling box, and an inlet pipe is provided on the cooling box.

[0009] Furthermore, the filter assembly includes a filter screen and a backwashing mechanism for cleaning the filter screen, both of which are mounted on the first transmission pipe.

[0010] Furthermore, the backwashing mechanism includes an inlet pipe and a drain pipe, both of which are installed on the first transmission pipe, and are respectively connected to both sides of the filter screen.

[0011] Furthermore, the backwashing mechanism also includes a flow sensor, two sets of first solenoid valves and second solenoid valves. The flow sensor is installed on the first transmission pipe and is located between the filter screen and the inlet pipe. The two sets of first solenoid valves are respectively installed on the inlet pipe and the drain pipe. The two sets of second solenoid valves are both installed on the first transmission pipe and are located at both ends of the first transmission pipe.

[0012] Furthermore, the lifting assembly includes a cylinder and a guide rod. The cylinder is mounted on the mounting frame, and the output end of the cylinder is mounted on the upper mold. The guide rod is slidably connected to the mounting frame, and one end of the guide rod is mounted on the upper mold.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the cooling component, cools the die-casting mold during the production of die-casting parts. The cooling pipe cools the die-casting mold, and the coolant flows in an S-shaped structure inside the mold, increasing the contact area between the coolant and the mold surface, thereby achieving the cooling of the mold and significantly improving the cooling efficiency, so that the die-casting parts can be cooled quickly.

[0015] 2. This utility model, through the setting of the filter component, effectively filters impurities in the coolant during the flow of coolant, preventing impurities in the coolant from clogging the pipes. At the same time, under the action of the backflushing mechanism, the filter screen can be automatically cleaned when it becomes clogged, reducing the frequency and difficulty of manual maintenance and lowering maintenance costs.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A die-casting mold with a circulating cooling structure.

[0024] The system includes a base plate 110, on which a lower mold 140 is mounted, a mounting frame 120 is mounted on the base plate 110, an upper mold 130 is mounted on the mounting frame 120, a lifting assembly for driving the upper mold 130 to move vertically is mounted on the mounting frame 120, a cooling assembly for cooling the lower mold 140 is mounted on the base plate 110, and a filter assembly for filtering the coolant is mounted on the cooling assembly.

[0025] The base plate 110 serves as the supporting foundation for the entire mold, and houses the lower mold 140 and the upper mold 130. The upper mold 130 moves vertically via a lifting assembly to cooperate with the lower mold 140 in completing the die-casting process. The cooling assembly is used to cool the lower mold 140, preventing overheating and product defects. The filtration assembly is used to purify the coolant, ensuring the long-term stable operation of the cooling system.

[0026] The cooling assembly includes an external cooling mechanism and a cooling pipe 310. The external cooling mechanism is mounted on the base plate 110, and the cooling pipe 310 is mounted inside the lower mold 140. The cooling pipe 310 has an S-shaped structure, and both ends of the cooling pipe 310 extend to both sides of the lower mold 140. Both ends of the cooling pipe 310 are connected to the external cooling mechanism.

[0027] The cooling assembly cools the lower mold 140 through an external cooling mechanism and cooling pipes 310. The cooling pipes 310 have an S-shaped structure, which increases the contact area between the coolant and the lower mold 140, thereby improving cooling efficiency. Both ends of the cooling pipes 310 are connected to the external cooling mechanism, forming a circulating cooling system.

[0028] The external cooling mechanism includes a cooling box 410, which is mounted on a base plate 110. A transfer pump 420 is installed at one end of the cooling box 410, and a first transfer pipe 430 is installed on the transfer pump 420. One end of the first transfer pipe 430 is connected to one end of the cooling pipe 310. A second transfer pipe 440 is installed at the other end of the cooling box 410, and one end of the second transfer pipe 440 is connected to the other end of the cooling pipe 310.

[0029] Under the action of the transfer pump 420, the coolant enters the cooling pipe 310 from the cooling tank 410 through the first transfer pipe 430, absorbs the heat of the mold, and then flows back to the cooling tank 410 through the second transfer pipe 440, realizing the transfer of heat and the recycling of coolant.

[0030] The cooling box 410 contains coolant, a semiconductor cooling chip is installed on one inner wall of the cooling box 410, and an inlet pipe is provided on the cooling box 410.

[0031] Cooling tank 410 is the storage and cooling area for the coolant. A thermoelectric cooler is installed on the inner wall of cooling tank 410. Through the thermoelectric effect of the cooler, heat is transferred from the inside of cooling tank 410 to the outside, thereby reducing the temperature of the coolant. An inlet pipe is used to replenish the coolant in cooling tank 410, ensuring an adequate supply of coolant. This design allows the coolant to maintain a lower temperature, thus cooling the mold more effectively.

[0032] The filter assembly includes a filter screen 510 and a backwashing mechanism for cleaning the filter screen 510, both of which are mounted on the first transmission pipe 430.

[0033] The function of the filter assembly is to keep the coolant clean and prevent impurities from clogging the cooling pipe 310 or affecting the cooling effect. The filter screen 510 is installed on the first transmission pipe 430 to intercept impurities in the coolant. The backflushing mechanism is used to periodically clean the filter screen 510 to prevent clogging. In this way, the coolant always maintains good flowability, extending the service life of the cooling system.

[0034] The backwashing mechanism includes an inlet pipe 610 and a drain pipe 620, both of which are installed on the first transmission pipe 430. The inlet pipe 610 and the drain pipe 620 are respectively connected to both sides of the filter screen 510.

[0035] The backwashing mechanism cleans the filter screen 510 through the inlet pipe 610 and the drain pipe 620. During normal operation, coolant passes through the filter screen 510 into the cooling pipe 310. When cleaning the filter screen 510 is required, a control valve reverses the water flow direction, directing the water into the inlet pipe 610, through the filter screen 510, and out through the drain pipe 620, thus washing away impurities from the filter screen 510. This design ensures effective cleaning of the filter screen 510 and improves the reliability of the cooling system.

[0036] The backwashing mechanism also includes a flow sensor 630, two sets of first solenoid valves and second solenoid valves 650. The flow sensor 630 is installed on the first transmission pipe 430 and is located between the filter screen 510 and the inlet pipe 610. The two sets of first solenoid valves 640 are respectively installed on the inlet pipe 610 and the drain pipe 620. The two sets of second solenoid valves 650 are both installed on the first transmission pipe 430 and are located at both ends of the first transmission pipe 430.

[0037] The flow sensor 630 in the backwashing mechanism monitors the coolant flow rate to ensure that the coolant circulation speed meets requirements. The first solenoid valve 640 and the second solenoid valve 650 are respectively installed on the inlet pipe 610, the drain pipe 620, and the first transmission pipe 430 to control the water flow direction and flow rate. By precisely controlling the opening and closing of these valves, automatic backwashing of the filter screen 510 can be achieved, improving the system's automation level and maintenance efficiency.

[0038] The lifting assembly includes a cylinder 210 and a guide rod 220. The cylinder 210 is mounted on the mounting frame 120, and the output end of the cylinder 210 is mounted on the upper mold 130. The guide rod 220 is slidably connected to the mounting frame 120, and one end of the guide rod 220 is mounted on the upper mold 130.

[0039] The lifting assembly controls the vertical movement of the upper mold 130, ensuring that it accurately engages or disengages from the lower mold 140. A cylinder 210 is mounted on the mounting bracket 120, with its output connected to the upper mold 130. The lifting and lowering of the upper mold 130 is achieved through the extension and retraction of the cylinder 210. A guide rod 220 is slidably connected to the mounting bracket 120, ensuring that the upper mold 130 maintains a stable and precise movement trajectory during lifting. This design makes the mold opening and closing smoother, improving the automation and reliability of the production process.

[0040] Specifically, the internal electrical connection structures of cylinder 210, semiconductor cooling chip, transfer pump 420, flow sensor 630, first solenoid valve 640, and second solenoid valve 650 are well known to those skilled in the art and will not be described in detail here. All electrical components appearing in this application are externally connected to a power source during use.

[0041] The circuits, electrical components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the software.

[0042] The control method described in this application is automatic control via a controller. The controller's control circuit can be easily implemented by those skilled in the art through simple programming, and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
