Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing technology, specifically a casting island for intelligent manufacturing of automotive engine parts. Background Technology

[0002] A casting island is an advanced manufacturing system that integrates automation, digitalization, and intelligent technologies. It is suitable for the efficient and precise production of core engine components. Its core typically includes an ultra-large die-casting island, core-making and mold-making equipment, cleaning and post-processing equipment, pouring and conveying equipment, as well as auxiliary and environmental protection equipment. Ultra-large die-casting islands generally use 6000T-16000T ultra-large die-casting islands (such as the Xindaer 16000T die-casting island). It can form complex structural parts such as engine blocks and chassis in one go, reducing welding steps and improving overall strength and production efficiency.

[0003] The optimal working temperature range for mold demolding is typically controlled between 180℃ and 280℃ (for aluminum alloy die casting); the ideal surface temperature is 150℃ to 300℃, which avoids defects such as cold shuts, flow lines, and sticking; the critical temperature limit is a minimum demolding temperature of ≥130℃, below which it is easy to cause undercasting, cracking, and cold shuts; the maximum safe temperature is ≤300℃, exceeding which it is easy to cause surface bubbles, shrinkage cavities, sticking, and mold thermal fatigue.

[0004] Existing post-molding cleaning and spraying processes for die-casting machines have significant drawbacks: When using compressed air for cleaning, the high-speed airflow coming into contact with the high-temperature mold causes rapid cooling of the mold surface due to excessive temperature differences, leading to thermal stress concentration and exacerbating the risk of mold fatigue cracks. Simultaneously, heat loss in the open space accelerates the overall temperature drop of the mold, increasing energy consumption and extending the production cycle. During the release agent spraying stage, the low-temperature release agent is prone to the Leidenfrost phenomenon upon contact with the high-temperature mold, causing droplets to form a vapor layer on the high-temperature surface that cannot penetrate, resulting in uneven release agent film formation and poor adhesion. This necessitates increasing the spraying frequency and dosage to maintain the demolding effect, wasting release agent and potentially causing defects such as porosity and cold shuts on the casting surface due to excessive residue. Furthermore, mold temperature fluctuations affect the casting solidification process, leading to uneven internal structure and decreased dimensional accuracy. Frequent temperature changes can damage the oxide layer on the mold surface, accelerating mold corrosion and carbon buildup. Additionally, release agents are prone to precipitation after prolonged storage. The combination of these problems not only reduces production efficiency and product quality but also increases mold maintenance costs and environmental pollution risks, such as the pressure on waste liquid treatment due to excessive use of release agents.

[0005] Therefore, the present invention provides a casting island for intelligent manufacturing of automotive engine parts that can heat and keep the mold release agent and compressed air at a low temperature, avoids the mold release agent from settling and precipitating, and has low energy consumption. Summary of the Invention

[0006] To address the problems of excessive temperature difference between the release agent and compressed air and the mold in existing technologies, and the rapid heat loss due to the open space of the mold, a casting island for intelligent manufacturing of automotive engine parts has been designed.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: a casting island for intelligent manufacturing of automotive engine parts, comprising a die-casting machine and a mold assembly fixed inside it. The mold assembly has two side partitions connected to its inner side. A top partition and a bottom partition are respectively provided at the top and bottom of the mold assembly. A heat preservation part is connected to the top of the die-casting machine. A spraying part is provided at the bottom of the heat preservation part. An air tank and a material tank are provided at the top of the spraying part. A mixing part is connected to one side of the side partition. The heat preservation part includes a threaded pipe fixed inside the air tank and an oil tank fixed outside the material tank. It heats and preserves the compressed air and release agent by guiding the coolant cooling the mold assembly to flow in a spiral direction inside the threaded pipe and the oil tank. The mixing part, in conjunction with the side partition, uses an anti-settling plate rotatably connected inside the material tank to turbulently prevent the release agent from settling during the process of sealing the mold assembly.

[0008] Furthermore, the module assembly includes a movable side module and a fixed side module, with the movable side module fixed to the movable mold base of the die-casting machine and the fixed side module fixed to the fixed mold base of the die-casting machine.

[0009] Furthermore, the insulation section also includes a base plate and a top cover. The top cover is fixed to the top of the die-casting machine, the base plate is fixed to the inside of the top cover, the top partition is fixed to the bottom of the base plate, two air tanks are fixed to the top of the base plate, and a material tank is fixed to the top of the base plate. The material tank is located on the side of the two air tanks that are close to each other. The oil outlet end of the movable mold base is connected to a connecting pipe three. The connecting pipe three is slidably snapped into the bottom of the base plate. The other end of the connecting pipe three and the oil outlet end of the fixed mold base are fixedly connected to a guide pipe. A threaded plate is fixed to the inside of the oil tank, and the inside of the threaded plate is fixed to the outside of the material tank.

[0010] Furthermore, the input ends of the threaded pipes inside the two gas storage tanks are fixedly connected to the side of the guide pipe near the connecting pipe three. The output end of the threaded pipe inside each gas storage tank is fixedly connected to the side of the guide pipe away from the connecting pipe three. Solenoid valve one is fixed at the connection position between the output end and the input end of each threaded pipe and the guide pipe. Solenoid valve two is fixed at the connection position between the guide pipe and the input end of the threaded pipe away from the connecting pipe three and the connection position between the guide pipe and the output end of the threaded pipe near the connecting pipe three.

[0011] Furthermore, a feed pipe is fixed to the top of the material tank, and both the oil inlet and outlet of the oil tank are connected to the guide pipe. Solenoid valve five is fixed inside both the oil inlet and outlet of the oil tank. The oil inlet of the oil tank and the input ends of the two threaded pipes are located on the same plane, and the oil outlet of the oil tank and the output ends of the two threaded pipes are located on the same plane. Solenoid valve four is fixed inside the feed pipe. One of the three-way valves is connected to the air inlet of the two air tanks. An air inlet channel is fixed to the top of the three-way valve. Another three-way valve is connected to the exhaust end of the two air tanks. An exhaust valve is connected to the bottom of the other three-way valve. Solenoid valve three is fixed inside both ends of the two three-way valves and the two air tanks.

[0012] Furthermore, a drive unit is connected to the bottom of the bottom partition plate. The drive unit includes a support plate and a motor. The support plate is fixed to the top of the base of the die-casting machine, and the bottom partition plate is fixed to the top of the support plate. A housing is fixed to the bottom of the support plate, and the motor is fixed to the bottom of the housing. The output end of the motor is connected to two sets of threaded rods through a belt and a pulley. The two threaded rods form a set, and the two side partition plates are respectively connected to the outside of the threaded rods through threads. The two side partition plates are slidably engaged with the outside of the top cover.

[0013] Furthermore, the spraying unit includes a connecting box. Two propulsion parts are fixed to the top of the substrate. The connecting box is fixed to the bottom of the two propulsion parts. A set of gas nozzles and fluid nozzles are fixed to both sides of the connecting box near the mold assembly. The gas nozzles are located on top of the fluid nozzles. Connecting pipe one and connecting pipe two are fixedly connected to the top of the connecting box. Connecting pipe one is located on one side of connecting pipe two. Gas channels and fluid channels are opened inside the connecting box. The gas channels are located on top of the fluid channels and are connected to the two sets of gas nozzles. The fluid channels are connected to the two sets of fluid nozzles. The other end of connecting pipe one is fixedly connected to an exhaust valve and is connected to the gas channels.

[0014] Furthermore, a liquid pump is fixed inside the connecting box, the output end of the liquid pump is connected to the liquid channel, one end of the connecting pipe is fixedly connected to the discharge port of the material tank, and the bottom of the connecting pipe is connected to the liquid pump through a bend.

[0015] Furthermore, the mixing section also includes a gear, and a transmission rod is rotatably connected to one side of the top cover. The gear is fixed to one end of the transmission rod located outside the material tank. One of the side covers has a toothed groove on the side near the top cover, and the gear meshes with the toothed groove. An anti-settling plate is fixed to the outside of the transmission rod, and a through hole is opened through the straight surface of the anti-settling plate. The cross-sectional area at both ends of the through hole is larger than the cross-sectional area in the middle.

[0016] Furthermore, a fixing plate is fixed to the bottom of the support plate, an air outlet valve is connected to one side of the fixing plate, and a filter plate is fixed to the inside of the support plate.

[0017] Furthermore, the motor, propulsion unit, liquid pump, exhaust valve, and all solenoid valves are electrically connected to the die-casting machine controller.

[0018] The beneficial effects of this invention are: (1) The casting island for intelligent manufacturing of automotive engine parts described in this invention is equipped with a die-casting machine and a heat preservation section. After the coolant absorbs heat by flowing through the mold assembly, it is transported through the guide pipe to the oil tank and the threaded pipe (made of high thermal conductivity copper alloy) inside the gas tank of the material tank. With the spiral groove design of the threaded plate and the threaded pipe, the flow path of the coolant is extended, and the heat transfer efficiency is enhanced by the turbulence effect. The temperature of the release agent is stabilized at 40-60℃ and the compressed air is maintained at 50-70℃ in the process window. When the temperature sensor detects that the medium exceeds the limit, the solenoid valve automatically switches the flow path, so that the residual heat flows into the heat exchanger quickly through the guide pipe for cooling and then flows back to the mold assembly. This reduces the risk of stress cracking caused by the temperature difference between the compressed air and the release agent and the mold assembly.

[0019] (2) The casting island for intelligent manufacturing of automotive engine parts described in this invention converts mechanical motion into fluid disturbance energy in the mixing section. When the motor drives the threaded rod to move the side partition down, the tooth groove of the side partition meshes with the gear of the transmission rod, forcing the anti-settling plate to rotate. The plate is designed with a double-cone through hole to form a Venturi effect - the release agent flows through the narrow section and the flow rate increases. After injection, it forms a 90° impact angle with the rotation direction of the plate, generating a high-intensity vortex, which increases the shear stress of the fluid in the tank and eliminates the sedimentation and stratification problem of high solid content release agent.

[0020] (3) The casting island for intelligent manufacturing of automotive engine parts described in this invention sprays hot air from a high-pressure gas nozzle to remove residual release agent and micro-shavings from the mold cavity. At the same time, the air compressor starts negative pressure suction to adsorb impurities to the ceramic filter plate inside the support plate to achieve impurity recovery. Then, the liquid pump pressurizes the release agent in the material tank and atomizes it into droplets through the nozzle. The circulation of compressed air further reduces the loss of heat from the compressed air.

[0021] (4) The casting island for intelligent manufacturing of automotive engine parts described in this invention can achieve efficient recovery of waste heat and directly use the waste heat of the mold for insulation of the material tank and the air tank, reducing the need for additional heat sources. The coolant flows through the material tank and the air tank for initial cooling, reducing the energy consumption of the heat exchanger. Furthermore, due to the sealed space formed by the side partitions and the heating of the release agent and compressed air, not only is the temperature difference between the compressed air and the release agent and the mold assembly reduced, but the heat loss of the mold assembly and the enclosed space is also reduced, thus reducing the energy consumption of the electric heating mold temperature controller.

[0025] To make the technical means, technical features, objectives, and effects of this invention easily understandable, the technical features of the prior art are first clarified. The integrated molding production of automotive chassis and large body structural components mainly relies on die casting processes. Ultra-large die casting islands (6000T-16000T level) integrating intelligent and automated technologies are currently the preferred choice for manufacturing. The workflow is simplified as follows: First, the mold is pretreated by spraying a release agent. It is important to note that the electric mold temperature controller can accurately control the temperature (±1℃). Graphite-based release paste is sprayed on the mold surface to prevent deep cavity castings from sticking together (especially suitable for complex structures such as automobile chassis).

[0026] Secondly, the cupola furnace (15-20 tons / hour) performs initial melting and the medium-frequency induction furnace refines the aluminum liquid, stabilizing the temperature at 680-720℃ (low-pressure casting) or 1380-1420℃ (cast iron). The composition is monitored in real time by a direct-reading spectrometer. Then, the molten metal is automatically transferred by AGV or robotic arm and injected into the injection chamber to avoid temperature fluctuations.

[0027] Finally, in the high-pressure die casting molding filling stage, the injection punch pushes the molten metal at a flow rate of ≥2kg / s, with a filling pressure of 0.02-0.06MPa (aluminum alloy). Equipment with a capacity of 6000T or more can achieve filling in ≤60 seconds. Pressurization and compaction are achieved through secondary pressurization by a multi-contact high-pressure system (pressure 100-175MPa) to eliminate shrinkage porosity and ensure the dense structure of large thin-walled parts (such as battery trays). This process is generally completed in about 10 seconds. It is necessary to use a combination of embedded heating wires and water cooling channels in the mold to reduce deformation through gradient temperature control, or to use a double demolding technology for cooling, i.e., the mechanism drives the inner and outer molds to separate synchronously to solve the problem of deep cavity parts sticking to the mold.

[0028] The present invention will be further described below with reference to specific embodiments.

[0029] Example 1: As Figures 1-19 As shown, the casting island for intelligent manufacturing of automotive engine parts according to the present invention includes a die-casting machine 1 and a mold assembly 2 fixed inside it. Two side partitions 3 are driven to the inner side of the mold assembly 2. A top partition 32 and a bottom partition 31 are respectively provided at the top and bottom of the mold assembly 2. A heat preservation section 8 is connected to the top of the die-casting machine 1. A spraying section 7 is provided at the bottom of the heat preservation section 8. An air storage tank 9 and a material tank 10 are provided at the top of the spraying section 7. A mixing section 11 is driven to one side of the side partitions 3. The heat preservation section 8 includes a threaded pipe 86 fixed inside the air storage tank 9 and an oil tank 85 fixed outside the material tank 10. It heats and preserves the compressed air and release agent by guiding the coolant cooling the mold assembly 2 to flow spirally inside the threaded pipe 86 and the oil tank 85. During the process of sealing the mold assembly 2 with the side partitions 3, the mixing section 11 utilizes an anti-settling plate rotatably connected inside the material tank 10. 114 The release agent is turbulent to prevent sedimentation. The mold assembly 2 includes a moving side module 22 and a fixed side module 21. The moving side module 22 is fixed to the moving mold base of the die casting machine 1, and the fixed side module 21 is fixed to the fixed mold base of the die casting machine 1. The heat preservation part 8 also includes a base plate 82 and a top cover 81. The top cover 81 is fixed to the top of the die casting machine 1, the base plate 82 is fixed to the inside of the top cover 81, the top partition plate 32 is fixed to the bottom of the base plate 82, two air tanks 9 are fixed to the top of the base plate 82, and the material tank 10 is fixed to the top of the base plate 82. The material tank 10 is located on the side of the two air tanks 9 that are close to each other. The oil outlet end of the moving mold base is connected to a connecting pipe 3 83. The connecting pipe 3 83 is slidably snapped into the bottom of the base plate 82. The other end of the connecting pipe 3 83 and the oil outlet end of the fixed mold base are fixedly connected to a guide pipe 84. The inner side of the oil tank 85 is fixed with a threaded plate 851. The inner side of the threaded plate 851 is fixed to the outer side of the material tank 10.

[0030] In this embodiment, the operator starts the external pump to circulate the coolant, opens solenoid valves one and five, closes solenoid valve two, and simultaneously controls the die-casting machine 1 to heat the mold assembly 2 using an electric mold temperature controller. The coolant absorbs heat as it flows through the mold assembly 2, and is kept warm as it passes through connecting pipe three 83 and guide pipe 84 (connecting pipe three 83, oil tank 85, and guide pipe 84 are made of insulating material). It dissipates heat after entering oil tank 85 and threaded pipe 86 (the portion of threaded pipe 86, threaded plate 851, and discharge pipe covered by oil tank 85 is made of thermally conductive material). Threaded plate 851... The threaded design of the threaded pipe 86 guides the coolant to flow forward while significantly increasing the contact area with the compressed air and the oil tank 85, thereby quickly transferring heat to the compressed air and mold release agent, increasing the storage temperature of the mold release agent and compressed air, and raising the mold assembly 2, mold release agent and compressed air to the ideal temperature. The mold assembly 2 needs a relatively high temperature of 20~250℃, the mold release agent temperature is 40-60℃, and the compressed air temperature is 50-70℃. Solenoid valve 1 and solenoid valve 5 are closed, and solenoid valve 2 is opened. The coolant only flows through the guide pipe 84 and does not enter the oil tank 85 and the threaded pipe 86. Workers used die-casting machine 1 to die-cast the engine housing 44, while simultaneously opening the heat exchanger (temperature sensors are fixed inside the material tank 10 and the air tank 9) to keep the mold assembly 2 warm during die-casting to ensure the quality of die-casting. When the temperature sensor detects that the temperature of the release agent and compressed air is 3°C higher than the ideal temperature limit, the operator closes the solenoid valve 2 by using the processor's solenoid valves 1 and 5. The coolant then recirculates the heat to the material tank 10 and the air storage tank 9 to heat the compressed air and release agent. After heating to 10°C higher than the ideal temperature, the operator closes the solenoid valves 1 and 5 and opens the solenoid valve 2 by using the processor. This allows the coolant to flow only through the guide pipe 84 and not into the oil tank 85 and the threaded pipe 86, thus utilizing the residual heat from the die-casting process of the die-casting machine 1 to heat and maintain the temperature of the compressed air.

[0031] Furthermore, the input ends of the threaded pipes 86 inside the two gas storage tanks 9 are fixedly connected to the side of the guide pipe 84 near the connecting pipe 3 83. The output end of the threaded pipe 86 inside each gas storage tank 9 is fixedly connected to the side of the guide pipe 84 away from the connecting pipe 3 83. A solenoid valve 1 is fixed at the connection points of the output and input ends of each threaded pipe 86 with the guide pipe 84. A solenoid valve 2 is fixed at the connection points of the guide pipe 84 and the threaded pipe 86, both away from and near the connecting pipe 3 83. A feed pipe 101 is fixed to the top of the material tank 10. The oil tank 8... Both the inlet and outlet ends of oil tank 85 are connected to the guide pipe 84. Solenoid valve 5 is fixed inside both the inlet and outlet ends of oil tank 85. The inlet end of oil tank 85 and the input ends of the two threaded pipes 86 are on the same plane. The outlet end of oil tank 85 and the output ends of the two threaded pipes 86 are on the same plane. Solenoid valve 4 is fixed inside the feed pipe 101. One of the three-way valves is connected to the air inlet end of the two air tanks 9. An air inlet channel 91 is fixed at the top of the three-way valve. Another three-way valve is connected to the exhaust end of the two air tanks 9. An exhaust valve 92 is connected to the bottom of the other three-way valve. Solenoid valve 3 is fixed inside both ends of the connection between the two three-way valves and the two air tanks 9.

[0032] In this embodiment, the operator fixes the air intake channel 91 to the output end of the air compressor, and then fixes the air compressor to the outlet valve through a pipeline. The oil outlet end of the guide pipe 84 is connected to the heat exchanger through a pipeline. The output end of the heat exchanger is fixedly connected to the oil inlet end of the mold assembly 2 through an external pump. The feed pipe 101 is fixedly connected to the pipeline for transporting the release agent. The solenoid valve four is opened to inject the mixed release agent into the material tank 10. When the release agent fills the material tank 10, the solenoid valve four is closed and the transport is stopped. The two solenoid valves three in one of the three-way valves are opened to start the air compressor. The air compressor draws outside air from the top of the filter plate 12 and enters its interior through the outlet valve. After compressing the air, it is pumped into the air intake channel 91 and finally stored inside the air storage tank 9. During this process, the filter plate 12 blocks impurities in the air to its top to prevent impurities from damaging the air compressor, the air storage tank 9 and other connecting pipelines. After the pressure inside the two air storage tanks 9 reaches the target pressure, the air compressor and the two solenoid valves three in one of the three-way valves are closed.

[0033] Furthermore, the spraying unit 7 includes a connecting box 71. Two propulsion parts are fixed to the top of the substrate 82. The connecting box 71 is fixed to the bottom of the two propulsion parts. A set of gas nozzles 72 and fluid nozzles 73 are fixed to both sides of the connecting box 71 near the mold assembly 2. The gas nozzles 72 are located on top of the fluid nozzles 73. A connecting pipe 1 74 and a connecting pipe 2 75 are fixedly connected to the top of the connecting box 71. The connecting pipe 1 74 is located on one side of the connecting pipe 2 75. A gas channel 77 and a fluid channel 78 are opened inside the connecting box 71. The gas channel 77 is located on top of the fluid channel 78 and communicates with the two sets of gas nozzles 72. The fluid channel 78 communicates with the two sets of fluid nozzles 73. The other end of the connecting pipe 1 74 is fixedly connected to the exhaust valve 92 and communicates with the gas channel 77.

[0034] In this embodiment, when the gas nozzle is located at the top of the module assembly 2, the exhaust valve 92 and one of the solenoid valves three in its top three-way valve are opened. The compressed air heated to the ideal temperature range flows through the exhaust valve 92, the connecting pipe 74, and the gas channel 77, and is then sprayed by the gas nozzle 72 onto the surfaces of the moving side module 22 and the fixed side module 21 to clean the surfaces of the moving side module 22 and the fixed side module 21. During the cleaning process after the second demolding, the air compressor can also be turned on to draw air, so that the gas in the formed sealed space flows out of the gas nozzle and is replenished to the inside of the gas storage tank 9. At the same time, the impurities blown off are pressed onto the filter plate 12 to prevent impurities from polluting the environment and equipment.

[0035] Furthermore, a liquid pump 76 is fixed inside the connecting box 71. The output end of the liquid pump 76 is connected to the liquid channel. One end of the connecting pipe 75 is fixedly connected to the discharge port of the material tank 10. The bottom of the connecting pipe is connected to the liquid pump 76 through a bend.

[0036] In this embodiment, after cleaning is completed, the operator closes the exhaust valve 92 and the solenoid valve three, stops the extension of the propeller 6, and turns on the liquid pump 76. Then, the operator controls the propeller 6 to retract, and sprays the release agent heated to the ideal temperature range onto the surfaces of the moving side module 22 and the fixed side module 21 through the connecting pipe two 75, the liquid pump 76 and the liquid nozzle to prevent liquid water from condensing until the connecting box 71 returns to its original position.

[0037] After the release agent is sprayed, the operator controls the motor 41 to reverse and drive the side partition 3 to return to its original position. At the same time, the transmission rod 111 drives the anti-settling plate 114 to reverse and stir the release agent again. Then, the operator controls the die-casting machine 1 to perform the next die-casting.

[0038] Furthermore, a drive unit 4 is connected to the bottom of the bottom partition 31. The drive unit 4 includes a support plate 42 and a motor 41. The support plate 42 is fixed to the top of the base of the die-casting machine 1, and the bottom partition 31 is fixed to the top of the support plate 42. A housing 44 is fixed to the bottom of the support plate 42, and the motor 41 is fixed to the bottom of the housing 44. The output end of the motor 41 is connected to two sets of threaded rods 43 via a belt and a pulley. The two threaded rods 43 form a set. The two side partitions 3 are respectively connected to the outside of the threaded rods 43 by threads. The two side partitions 3 are slidably engaged with the outside of the top cover 81. The mixing part 11 also includes a gear 112. The top cover... A transmission rod 111 is rotatably connected to one side of 81. A gear 112 is fixed to one end of the transmission rod 111 located outside the material tank 10. A toothed groove 113 is provided on one side of the side cover near the top cover 81. The gear 112 meshes with the toothed groove 113. An anti-sedimentation plate 114 is fixed to the outside of the transmission rod 111. A through hole 115 is provided through the straight surface of the anti-sedimentation plate 114. The cross-sectional area at both ends of the through hole 115 is larger than the cross-sectional area in the middle. A fixing plate 121 is fixed to the bottom of the support plate 42. An air outlet valve is connected to one side of the fixing plate 121. A filter plate 12 is fixed to the inside of the support plate 42.

[0039] In this embodiment, before the first die casting and after each demolding, the operator controls the motor 41 to rotate forward. The motor 41 drives four threaded rods 43 to rotate forward via a belt and pulley. The threaded rods 43 drive the two side partitions 3 to move along the outside of the top cover 81 towards the bottom of the die casting machine 1. After the side partitions 3, top partition 32, bottom partition 31, support plate 42, and base plate 82 mold assembly 2 form a sealed space, the propulsion component 6 (which can be a hydraulic cylinder or other device capable of radial extension and retraction) is controlled to extend. The propulsion component 6 pushes the connecting box 71 to move towards the side closer to the support plate 42. The connecting box 71 stretches the connecting pipe 1 74 and the connecting pipe 2 75 (connecting pipe 1 74 and connecting pipe 2 75). The second connecting pipe 75 can be configured as a bellows or other device for conveying liquids or gases. At the same time, the side partition 3 drives the toothed groove 113 to move. The toothed groove 113 drives the gear 112 to rotate forward through meshing. The gear 112 drives the transmission shaft to rotate forward. The transmission shaft drives the anti-settling plate 114 to rotate forward. The anti-settling plate 114 stirs the release agent, causing the release agent to rotate forward. When the release agent flows through the through hole 115, the cross-sectional area of ​​the through hole 115 first decreases and then recovers after entering the through hole 115. The flow rate of the release agent increases and then it is ejected from the other side of the through hole 115, colliding with the rotating release agent. This locally disrupts the flow direction of the release agent, greatly increases the stirring effect, and prevents the release agent from settling.

[0040] Working principle: Initial state as follows Figure 1-18As shown, the operator starts the external pump to circulate the coolant. The coolant absorbs heat as it flows through the mold assembly 2, is kept warm as it passes through the connecting pipe 3 83 and the guide pipe 84, and dissipates heat after entering the oil tank 85 and the threaded pipe 86, raising the mold assembly 2, the release agent, and the compressed air to the ideal temperature. The operator uses the die-casting machine 1 to die-cast the engine housing 44, while simultaneously opening the heat exchanger to keep the mold assembly 2 warm during die-casting. When the temperature sensor detects that the temperature of the release agent and the compressed air is 3°C higher than the ideal temperature limit, the coolant recirculates the heat back to the material tank 10 and the air storage tank 9 to heat the compressed air and the release agent. After heating to 10°C higher than the ideal temperature, the operator closes the solenoid valves 1 and 5 and opens the solenoid valve 2 through the processor to heat and keep the compressed air warm. Before the first die casting and after each demolding, the operator controls the motor 41 to rotate forward, driving the two side partitions 3 to move along the outside of the top cover 81 towards the bottom of the die casting machine 1. After the side partitions 3, top partition 32, bottom partition 31, support plate 42, and base plate 82 mold assembly 2 form a sealed space, the operator controls the pusher 6 to extend. The pusher 6 pushes the connecting box 71 to move closer to the support plate 42. At the same time, the side partitions 3 drive the toothed groove 113 to move. The toothed groove 113 drives the gear 112 to rotate forward through meshing. The transmission shaft drives the anti-settling plate 114 to rotate forward. The anti-settling plate 114 stirs the release agent, causing it to rotate in the correct direction and preventing it from settling. When the gas nozzle is at the top of the mold assembly 2, the exhaust valve 92 and one of the solenoid valves 3 are opened, and compressed air is sprayed onto the surfaces of the moving side module 22 and the fixed side module 21 to clean them. After cleaning, the operator controls the pusher 6 to retract, spraying the release agent heated to the ideal temperature range onto the surfaces of the moving side module 22 and the fixed side module 21 to prevent liquid water from condensing.
