Abstract

This utility model discloses a stable cooling structure for casting molds, including an upper mold, a lower mold, a water-cooling component, and an air-cooling component. The water-cooling component is a ring-shaped structure, slidably connected to the lower mold, and surrounds the three sides of the upper and lower molds. The water-cooling component is connected to the lower mold via a first stabilizer and to the upper mold via a second stabilizer. The air-cooling component is detachably connected to the water-cooling component and abuts against one side of the upper and lower molds after they are closed.

Description

Technical Field

[0001] This utility model belongs to the technical field of casting molds, specifically a stable cooling structure for casting molds. Background Technology

[0002] Low-pressure casting is a casting method that uses gas pressure to force molten metal from a crucible into a mold cavity through a riser pipe. The molten metal fills the mold from bottom to top under low pressure, and the filling speed is controllable. The solidification process is completed under pressure, thus forming high-quality castings. This process is widely used to produce light metal parts such as aluminum alloys and magnesium alloys, such as automobile wheel hubs, engine blocks, and LED bracket frames.

[0003] Existing technologies, such as the "low-pressure casting machine" disclosed in patent document "CN210387535U", use natural cooling methods for cooling, as do most low-pressure casting molds on the market. This method has a slow cooling speed. Some manufacturers have introduced molds with fixed water-cooling components, which improves cooling efficiency but also increases the cost of the molds. This is especially true for molds used to manufacture small batches of products or customized products. After use, the water-cooling components are stored with the molds, which increases the manufacturing cost of the molds and wastes the resources of the water-cooling components. Utility Model Content

[0004] The purpose of this invention is to provide a stable cooling structure for casting molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stable cooling structure for a casting mold includes an upper mold, a lower mold, a water-cooling component, and an air-cooling component. The upper mold and lower mold form a cavity when closed. A gate is provided at the bottom of the lower mold. The water-cooling component is annular and slidably connected to the lower mold. The water-cooling component is arranged around three sides of the upper and lower molds and is connected to the lower mold via a first stabilizer and to the upper mold via a second stabilizer. The air-cooling component is detachably connected to the water-cooling component and abuts against one side of the upper and lower molds after they are closed. The air-cooling component is connected to the upper mold via a third stabilizer.

[0007] In a further technical solution, the water-cooling assembly includes a water-cooling section, and two long sliders are provided on both sides of the inner sidewalls of the water-cooling section. The lower mold is provided with a sliding groove, and the long sliders are slidably connected to the sliding groove.

[0008] In a further technical solution, the water-cooling component also includes a load-bearing block and a water pump located on the load-bearing block, wherein the water pump and the water-cooling channel in the water-cooling section are respectively connected through an inlet pipe and an outlet pipe.

[0009] In a further technical solution, slots are provided on both sides of the inner wall of the water-cooled section away from the water pump. The air-cooled component includes a heat dissipation shell, heat dissipation fins located inside the shell, and a fan. The fan is connected to the heat dissipation shell, and connecting blocks are provided at both ends of the heat dissipation shell. The connecting blocks are inserted into the slots.

[0010] A further technical solution includes a stabilizing component comprising a threaded post, a buffer spring, and a rotating block. A protrusion and a clearance groove are provided on one side of the lower mold. The protrusion abuts against the bottom surface of the side wall of the water-cooling part. The protrusion has a clearance hole. The water-cooling part has a threaded groove aligned with the clearance hole. One end of the threaded post is threadedly connected to the threaded groove, and the other end of the threaded post is fixedly connected to the rotating block. The buffer spring is sleeved on the threaded post. One end of the buffer spring is fixedly connected to the rotating block, and the other end of the buffer spring abuts against the protrusion.

[0011] In a further technical solution, the second stabilizing component includes a stabilizing ring, a guide post, and a stabilizing post. The stabilizing post is fixedly connected to the water-cooling part. The stabilizing post has a groove with an internal thread. One end of the guide post has an external thread, and the threaded end of the guide post is threadedly connected to the groove. A fixing block extends from the outer wall of the stabilizing ring and is fixedly connected to the upper mold. The stabilizing ring is slidably connected to the guide post.

[0012] In a further technical solution, the stabilizing component three includes a guide post two and a stabilizing post two. The stabilizing post two is fixedly connected to the heat dissipation shell. The stabilizing post two has a groove two with an internal thread. One end of the guide post two has an external thread, and the threaded end of the guide post two is threadedly connected to the groove two. The upper mold extends with a flange, and the other end of the guide post two is slidably connected to the wall of the sliding hole of the flange.

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

[0014] When installing the low-pressure casting mold stabilizing and cooling structure of this utility model, the first step is to align the upper mold and lower mold and close them to form a casting cavity, ensuring mold closing accuracy. The bottom gate of the lower mold is installed in place, ready to inject molten metal. The second step is to take the annular water-cooling component and slide it into the preset groove of the lower mold, so that the water-cooling component surrounds the three sides of the upper and lower molds and fits tightly against the outer wall of the mold. Stabilizer one is used to keep the water-cooling component and the lower mold in a fixed position. Stabilizer two is used to connect the water-cooling component to the upper mold, ensuring that the water-cooling component is not squeezed or displaced during mold closing and demolding, and preventing mold deformation. The third step is to connect the air-cooling component to the water-cooling component, abutting against the fourth side after the upper and lower molds are closed, and fix it with a detachable connection. Stabilizer three is used to connect the air-cooling component to the upper mold, ensuring overall stability.

[0015] In addition, the combination of water-cooled and air-cooled components improves the cooling speed compared to natural cooling, thereby shortening the solidification time of castings and increasing production efficiency.

[0016] In addition, for small-batch and customized molds, detachable water-cooling and air-cooling components are adopted, which improves the installation flexibility of the mold and the water-cooling components, and the mold and the air-cooling components. When a batch of customized molds is used up, the water-cooling and air-cooling components can be removed and installed in the next batch of customized molds, reducing the inventory of air-cooling and water-cooling components and improving the utilization rate of cooling equipment resources. Through stabilizer one, stabilizer two and stabilizer three, the precise fit between the water-cooling components, air-cooling components and mold is ensured. On the one hand, the fit improves the heat dissipation efficiency, and on the other hand, it prevents mold closing deviation, so that the mold can cool down and dissipate heat stably.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-6 ;

[0027] This embodiment discloses a stable cooling structure for a casting mold, including an upper mold 1, a lower mold 2, a water-cooling component 3, and an air-cooling component 4. After the upper mold 1 and lower mold 2 are closed, a cavity 5 is formed. A gate component 6 is provided at the bottom of the lower mold 2. The water-cooling component 3 has a ring-shaped structure and is slidably connected to the lower mold 2. The water-cooling component 3 is arranged around the three sides of the upper mold 1 and lower mold 2, and is connected to the lower mold 2 by a stabilizing component 7. When the water-cooling component 3 is in use, the upper mold 1 and lower mold 2 are first closed, and then the water-cooling component 3 is slidably connected to the lower mold 2, allowing the water-cooling component 3 to be inserted into the lower mold 2. The water-cooling component 3 is connected to the upper mold 1 and lower mold 2... The outer wall is fitted together, and then the water-cooling component 3 is connected to the upper mold 1 through the second stabilizer 8 to prevent deviation during the mold closing process of the upper mold 1 and the lower mold 2 from causing the upper mold 1 and the water-cooling component 3 to be squeezed; the air-cooling component 4 is detachably connected to the water-cooling component 3, and the air-cooling component 4 abuts against one side of the upper mold 1 and the lower mold 2 after the mold is closed. That is, the water-cooling component 3 is first fitted to the three sides of the upper mold 1 and the lower mold 2, and then the air-cooling component 4 is fitted to the water-cooling component 3, so that the air-cooling component 4 can fix the water-cooling component 3 while further improving the heat dissipation effect. Multiple heat dissipation methods are used to improve heat dissipation efficiency. The air-cooling component 4 is connected to the upper mold 1 through the third stabilizer 9.

[0028] Specifically, when installing the low-pressure casting mold stabilization and cooling structure, the first step is to align and close the upper mold 1 and lower mold 2 to form the casting cavity, ensuring mold closing accuracy. The bottom gate component 6 of the lower mold 2 is installed in place, ready for the injection of molten metal. The second step is to take the annular water-cooling component 3 and slide it into the preset groove of the lower mold 2, so that the water-cooling component 3 surrounds the three sides of the upper mold 1 and lower mold 2 and fits tightly against the outer wall of the mold. Stabilizer 1 7 is used to keep the water-cooling component 3 and the lower mold 2 in a fixed position. Stabilizer 2 8 is used to connect the water-cooling component 3 to the upper mold 1, ensuring that the water-cooling component 3 is not squeezed or displaced during mold closing and demolding, preventing mold deformation. The third step is to connect the air-cooling component 4 to the water-cooling component 3, abutting against the fourth side after the upper mold 1 and lower mold 2 are closed, and fix it with a detachable connection. Stabilizer 3 9 is used to connect the air-cooling component 4 to the upper mold 1. The combination of water-cooled component 3 and air-cooled component 4 ensures overall stability. The combined heat dissipation of water-cooled component 3 and air-cooled component 4 increases the cooling speed compared to natural cooling, thereby shortening the solidification time of the casting and improving production efficiency. In addition, for small-batch and customized molds, detachable water-cooled component 3 and air-cooled component 4 are used, which improves the installation flexibility of the mold and water-cooled component 3 and the mold and air-cooled component 4. When a batch of customized molds is used up, water-cooled component 3 and air-cooled component 4 can be removed and installed in the next batch of customized molds, reducing the inventory of air-cooled component 4 and water-cooled component 3 and improving the resource utilization rate of cooling equipment. Through stabilizer 1 7, stabilizer 2 8 and stabilizer 3 9, the precise fit between water-cooled component 3, air-cooled component 4 and mold is ensured. On the one hand, the fit improves the heat dissipation efficiency, and on the other hand, it prevents mold closing deviation, so that the mold can cool down and dissipate heat stably.

[0029] It is worth noting that the cavity 5 formed between the upper mold 1 and the lower mold 2 can be fixedly provided with a molded body 10 to meet the needs of the molded product, but this is not limited in this embodiment.

[0030] In this embodiment, the water-cooling component 3 further includes a water-cooling section 31, which has a circulating water-cooling channel. The water-cooling section 31 has a "U"-shaped design with an opening on one side. Two long sliders 32 are provided on both sides of the inner sidewall of the water-cooling section 31. The lower mold 2 is provided with a sliding groove 21. The length of the sliding groove 21 is the same as the length of the long sliders 32, and the long sliders 32 are slidably connected to the sliding groove 21. This further increases the contact area between the water-cooling section 31 and the lower mold 2, improves the stability of the water-cooling section 31 relative to the lower mold 2, and improves the convenience of installation. The operator only needs to face the opening of the water-cooling section 31 toward the mold and insert the long sliders 32 into the sliding groove 21.

[0031] In this embodiment, the water-cooling component 3 further includes a load-bearing block 33 and a water pump 34 located on the load-bearing block 33. The water pump 34 and the water-cooling channel in the water-cooling section 31 are connected through an inlet pipe 35 and an outlet pipe 36, respectively. In addition, the water pump 34 is also connected to an external water-cooling device, so that the cooling water in the water-cooling channel in the water-cooling section 31 is continuously exchanged with the external water-cooling device to improve the heat dissipation efficiency.

[0032] Furthermore, slots 37 are provided on both sides of the inner wall of the water-cooled section 31 away from the water pump 34. The air-cooled component 4 includes a heat dissipation shell 41, heat dissipation fins 42 located inside the shell, and a fan 43. The fan 43 is connected to the heat dissipation shell. The connection method between the heat dissipation fins 42 and the heat dissipation shell 41, and between the fan 43 and the heat dissipation shell 41 is a conventional method, so it is not limited in this embodiment. Connecting blocks 44 are provided at both ends of the heat dissipation shell 41, and the connecting blocks 44 are inserted into the slots 37.

[0033] Specifically, during installation, the long slider 32 of the water-cooling part 31 is first inserted into the sliding groove 21. At this time, the groove wall of the slot 37 is aligned with the side wall of the lower mold 2. Then, the connecting block 44 is inserted into the slot 37 from the vertical direction. At this time, the heat dissipation fins 42 are simultaneously attached to the fourth side of the upper mold 1 and the lower mold 2, so that the air-cooling component 4 can fix the water-cooling component 3 while further improving the heat dissipation effect.

[0034] In this embodiment, the stabilizing component 7 includes a threaded post 71, a buffer spring 72, and a rotating block 73. A protrusion 22 and a clearance groove 23 are provided on one side of the lower mold 2. The protrusion 22 abuts against the bottom surface of the side wall of the water-cooling part 31. The protrusion 22 has a clearance hole. The water-cooling part 31 has a threaded groove aligned with the clearance hole. One end of the threaded post 71 is threadedly connected to the threaded groove, and the other end of the threaded post 71 is fixedly connected to the rotating block 73. The buffer spring 72 is sleeved on the outside of the threaded post 71. One end of the buffer spring 72 is fixedly connected to the rotating block 73, and the other end of the buffer spring 72 abuts against the protrusion 22.

[0035] Specifically, during installation, first insert the long slider 32 of the water-cooled part 31 into the sliding groove 21. At this time, the clearance hole and the groove opening of the threaded groove are aligned. Then, put the buffer spring 72 into the threaded post 71, and then thread the threaded post 71 through the clearance hole and threadedly connect it to the threaded groove. At this time, the buffer spring 72 is in a compressed state to prevent the water-cooled part 31 from deviating from the lower mold 2 due to vibration during mold closing and demolding.

[0036] In this embodiment, the second stabilizer 8 includes a stabilizing ring 81, a guide post 82, and a stabilizing post 83. The stabilizing post 83 is fixedly connected to the water-cooling part 31. The stabilizing post 83 has a groove 84 with an internal thread. One end of the guide post 82 has an external thread, and the end of the guide post 82 with the external thread is threadedly connected to the groove 84. A fixing block 85 extends from the outer wall of the stabilizing ring 81 and is fixedly connected to the upper mold 1. The stabilizing ring 81 and the guide post 82 are slidably connected. Furthermore, the stabilizing component 3 9 includes guide post 2 91 and stabilizing post 2 92. Stabilizing post 2 92 is fixedly connected to the heat dissipation shell 41. Stabilizing post 2 92 has a groove 2 with an internal thread. One end of guide post 2 91 has an external thread, and the end of guide post 2 91 with the external thread is threadedly connected to the groove 2. The upper mold 1 extends with a flange 11, and the other end of guide post 2 91 is slidably connected to the wall of the sliding hole 111 of flange 11.

[0037] Specifically, during installation, the guide post 82 is threaded through the stabilizing ring 81 and connected to the groove 84, so that when the upper mold 1 moves, the stabilizing ring 81 moves with the guide post, which further improves the stability of the upper mold 1 relative to the water-cooling part 31.
