[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a die-casting mold for a front cover of an automobile engine, comprising a frame 1, a hydraulic rod 2 is fixedly connected inside the frame 1, an upper mold 3 is fixedly connected to the output end of the hydraulic rod 2, a connecting rod 1 5 is fixedly connected to the top of the upper mold 3, a lower mold 4 is fixedly connected inside the frame 1, a support column 6 is fixedly connected inside the frame 1, a fixed plate 7 is slidably connected to the outer wall of the support column 6, a push rod 9 is fixedly connected to the top of the fixed plate 7, the outer wall of the push rod 9 is penetrated between the lower mold 4 and the inside of the frame 1, a reset component is arranged on the outer wall of the support column 6, a connecting rod 2 8 is fixedly connected to one side of the fixing plate 7, the connecting rod 2 8 is buckled with the outer wall of the connecting rod 1 5, and the reset component comprises a spring 10, one end of the spring 10 is fixedly connected to the inside of the frame 1, and the other end of the spring 10 is fixedly connected to the top of the fixing plate 7;

[0031] Specifically, first, the operator places the raw material to be die-cast on the lower mold 4. This raw material is usually a metal block or particle that has been specially treated to adapt to the subsequent die-casting process. Next, the output end of the hydraulic rod 2 extends to drive the upper mold 3 to descend. In this step, the upper mold 3 and the lower mold 4 are buckled together to form a closed space. This space is the place where the molten metal cools and solidifies, and its shape and size are determined by the design of the mold. When the mold is closed, the molten metal is injected into the mold. Due to the limited space inside the mold, the molten metal quickly fills the entire mold under high pressure, eliminating the air and impurities therein. This step is the key to die-casting, which determines the quality and precision of the parts. Subsequently, the output end of the hydraulic rod 2 retracts, driving the upper mold 3 to lift. At this time, the metal inside the mold has cooled and solidified to form the required parts. At the same time, the output end of the hydraulic rod 2 also drives the connecting rod 1 5 to lift. The connecting rod 1 5 is buckled with the connecting rod 2 8, so when the connecting rod 1 5 is lifted, the connecting rod 2 8 will also be driven to lift. The lifting of the connecting rod 2 8 drives the ejector 9 to extend out of the lower mold 4 through the fixed plate 7. This process ejects the part inside the lower mold 4 out of the mold, making it easy for the operator to remove it. The design and position of the ejector pin 9 are critical, and they need to be precisely controlled to ensure that the part is completely ejected from the mold. When the next part is ready to be die-cast, the connecting rod 1 5 extends and descends through the output end of the hydraulic rod 2. At this time, the connecting rod 2 8 will push the ejector pin 9 back down through the tension of the spring 10. The tension of the spring 10 is the key factor in this step, which ensures that the ejector pin 9 can be accurately reset after each operation to prepare for the next die-casting.

[0032] Reference Figure 3 and Figure 4 A bracket 11 is fixedly connected to one side of the frame 1, a box 12 is fixedly connected to the top of the bracket 11, a top cover 13 is arranged on the top of the box 12, a cooling pipe 14 is fixedly connected to the inside of the box 12, the outer wall of the cooling pipe 14 is passed through the inside of the lower mold 4, one end of the cooling pipe 14 is fixedly connected to the inside of the box 12, a water pump 15 is fixedly connected to the other end of the cooling pipe 14, the output end of the water pump 15 is fixedly connected to the other end of the cooling pipe 14, the input end of the water pump 15 is fixedly connected to the inside of the box 12, a fixing ring 16 is fixedly connected to the inside of the box 12, a frame 17 is arranged inside the box 12, a filter screen 19 is fixedly connected to the inside of the frame 17, a handle 18 is rotatably connected to the top of the frame 17, a card slot 20 is opened inside the frame 17, a sealing ring 21 is arranged inside the frame 17, and the outer wall of the sealing ring 21 is embedded in the card slot 20;

[0033] Specifically, in the production process, die casting is a key step, but it inevitably causes a large amount of heat to be generated by the upper mold 3 and the lower mold 4. In order to effectively manage this heat and ensure the smooth progress of the production process, an efficient cooling system becomes crucial. In this system, the heat of the lower mold 4 is dissipated through the circulation of coolant. Specifically, the coolant is first extracted from the inside of the box 12 through the input end of the water pump 15. The water pump 15 is a key component that is responsible for driving the flow of the coolant to ensure that the heat can be transferred quickly. After the coolant is pumped out through the output end of the water pump 15, it flows into the inside of the cooling pipe 14. These cooling pipes 14 are cleverly arranged inside the lower mold 4, so that they can directly contact the mold and quickly absorb the heat from the mold. When the coolant flows in the cooling pipe 14, it absorbs the heat of the mold, thereby cooling the mold. Subsequently, the coolant that has absorbed the heat flows back to the inside of the box 12 through the other end of the cooling pipe 14. During the reflux process, the coolant first passes through the filter screen 19 inside the box 12. This filter 19 can not only effectively filter out impurities and particulate matter in the coolant and keep the coolant clean, but also extend the service life of the cooling system. The filter 19 is fixed by the frame 17. The design of the frame 17 ensures the stability and reliability of the filter 19, so that it can work effectively for a long time. At the same time, the frame 17 is placed on the fixed ring 16 for limiting, so that the filter 19 can be prevented from shifting or deforming during the flow of the coolant. In addition, a sealing ring 21 is used to seal between the frame 17 and the housing 12. The presence of this sealing ring 21 can prevent the coolant from flowing through the gap between the frame 17 and the housing 12, thereby ensuring the sealing and efficiency of the cooling system.

[0034] Working principle: When using the automobile engine front cover die-casting mold, first place the raw material on the lower mold 4, then the output end of the hydraulic rod 2 extends to drive the upper mold 3 to descend, and the upper mold 3 and the lower mold 4 are engaged with each other to die-cast the raw material, and then the output end of the hydraulic rod 2 retracts to drive the upper mold 3 to lift, and at the same time, the output end of the hydraulic rod 2 will simultaneously drive the connecting rod 1 5 to lift, and the connecting rod 1 5 is engaged with the connecting rod 2 8, so when the connecting rod 1 5 is lifted, the connecting rod 2 8 is also lifted, and when the connecting rod 2 8 is lifted, the ejector 9 is extended out of the lower mold 4 through the fixed plate 7, and the parts inside the lower mold 4 are ejected out of the mold, which is convenient for the operator to remove, and when the next part is die-cast, the connecting rod 1 5 is extended and descended through the output end of the hydraulic rod 2, and the connecting rod 2 8 will push the ejector through the tension of the spring 10. The rod 9 is reset and descended, and then the above steps are repeated for production. During the production process, die casting will cause the upper mold 3 and the lower mold 4 to heat up, so the lower mold 4 extracts the coolant inside the box 12 through the input end of the water pump 15, pumps it out through the output end of the water pump 15 and flows into the cooling pipe 14. The cooling pipe 14 is penetrated inside the lower mold 4, and the heat of the lower mold 4 is taken away by the coolant, and then it returns to the box 12 through the other end of the cooling pipe 14, so that the coolant is filtered through the filter screen 19 in the box 12. The filter screen 19 is fixed by the frame 17, and the frame 17 is placed on the fixing ring 16 for limiting. At the same time, the frame 17 and the box 12 are sealed by the sealing ring 21 to prevent the coolant from flowing through the gap between the frame 17 and the box 12.
