DETAILED DESCRIPTION

[0015] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0016] Example 1: This embodiment provides a metal component casting system, comprising: Several casting mechanisms for casting metal parts; The external circulation temperature control mechanism is used to deliver coolant to the casting mechanism to cool it down during the die-casting process; The casting mechanism includes: The frame 1 includes a base and a support base that are symmetrical in both directions, and a plurality of guide rods are provided between the base and the support base; Fixed mold 2, fixedly arranged on the base; The movable seat is located directly above the base and is limited by the guide rod to move up and down; The movable mold 3 is arranged on the movable seat; The driving component is arranged on the support seat, and its driving end drives the piston seat to move up and down; A cooling channel 4 is formed in both the fixed mold 2 and the movable mold 3 , and an external circulation temperature control mechanism is connected to the cooling channel 4 to provide cooling liquid therefor.

[0017] In this technical solution, an external circulation temperature control mechanism provides coolant at a stable temperature to multiple casting mechanisms while simultaneously cooling the heated coolant exiting the casting mechanisms. This ensures effective cooling during the casting cooling process and the quality of the cast products. Furthermore, by providing coolant to multiple casting mechanisms through a single external circulation temperature control mechanism, its utilization rate is increased and the cooling cost of each casting mechanism is reduced.

[0018] Example 2: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0019] The external circulation temperature control mechanism includes: A cooling and heat preservation water tank 5, in which coolant is stored; A cooling delivery pipeline for delivering coolant to the cooling channel 4 of the casting mechanism; The cooling return line is used to receive the coolant discharged from the casting mechanism, cool the coolant, recycle it, and transport it back to the cooling and insulation water tank 5; The cooling pipeline includes: Several parallel main pumping pipelines 6, one end of which is connected to the water outlet of the cooling and heat preservation water tank 5, and a main delivery pump 7 is provided in the middle of the pipeline; Several secondary pumping pipelines 8, two or more of which are connected in parallel and connected to the same main pumping pipeline 6 at one end; and a secondary delivery pump 9 is provided in the middle of each secondary pumping pipeline 8; The other end of the secondary pumping pipeline 8 is connected in parallel with a plurality of water supply branches 10 which are respectively connected to the cooling channels 4 of the movable mold 3 and the fixed mold 2 in a casting mechanism.

[0020] In this technical solution, the cooling and thermal insulation water tank 5 is used to store coolant for cooling the casting mechanism, and also receives the heated coolant discharged from the casting mechanism and cooled. The cooling and thermal insulation water tank 5 also provides thermal insulation. The capacity of the cooling and thermal insulation water tank 5 is adjusted according to the number of casting mechanisms in the system. For example, a casting mechanism requires a cooling and thermal insulation water tank 5 capacity of 0.8-1.5 cubic meters. The cooling delivery pipeline transports the coolant in the cooling and thermal insulation water tank 5 to the casting mechanism. The return cooling pipeline receives the coolant discharged from the casting mechanism, collects it, and cools it until it reaches the required temperature.

[0021] The main pump delivery pipeline in the cooling delivery pipeline is used to pressurize and pump the coolant in the cooling and insulation water tank 5 outward; the secondary pump delivery pipeline 8 is set to further pressurize and deliver the coolant pumped by the corresponding main pump delivery pipeline to the casting mechanism on the corresponding water supply branch 10, wherein each water supply branch 10 is provided with a water supply control valve, which is opened when the casting mechanism needs coolant and closed when coolant is not needed; and two pipelines are connected in parallel at the end of the water supply branch 10, respectively connected to the cooling flow channel 4 in the fixed mold 2 and movable mold 3 in the same casting mechanism. At the same time, because both the main pump delivery pipeline 6 and the secondary pump delivery pipeline 8 are equipped with delivery pumps, the water pressure and flow rate of the coolant delivery can be guaranteed when providing coolant to multiple casting mechanisms.

[0022] Example 3: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] The cooling return line includes: There are several return branch pipes 12, and one end of each is used to receive the coolant discharged from the cooling channel 4 of a casting mechanism; The return water main 13 is connected to the other ends of the return water branches 12; The coolant condition detection component 14 is provided on the return water main 13 and is used to detect the temperature and flow rate of the coolant discharged from the casting mechanism; The cooling grading assembly is connected to the other end of the return water main 13 and is used to grade the cooling liquid discharged from the casting mechanism.

[0024] In this technical solution, the return branch pipe 12 receives the heated coolant discharged from the casting mechanism, and the return main pipe 13 transports the coolant discharged from the multiple casting mechanisms to facilitate subsequent cooling of the coolant. The cooling condition detection assembly monitors the water temperature and flow rate of the coolant discharged from the casting mechanism in the return main pipe 13. This allows the cooling stage assembly to perform appropriate cooling based on the coolant's temperature and flow rate, thereby ensuring that the water returned to the cooling and insulation water tank 5 is at a temperature sufficient to cool the casting mechanism.

[0025] Example 4: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] The cooling stage assembly includes: The main cooling pipe 15 is connected to the return water pipe 13 at one end and is provided with a main cooler 16 at the other end; wherein the inlet end of the main cooler 16 is connected to the other end of the main cooling pipe 15, and the outlet end is connected to the cooling and insulation water tank 5 through a pipe; A secondary cooling pipe 17 is connected at one end to the middle of the main cooling pipe 15 and is provided with a secondary cooler 18 at the other end; wherein the inlet end of the secondary cooler 18 is connected to the other end of the secondary cooling pipe 17, and the outlet end is connected to the cooling and insulation water tank 5 through a pipe; The main switching valve 19 is arranged at the connection between the secondary cooling pipeline 17 and the main cooling pipeline 15; it is used to control one end of the main cooling pipeline 15 to be connected to the other end of the main cooling pipeline 15 or to be connected to the other end of the main cooling pipeline 15 and the secondary cooling pipeline 17 at the same time.

[0027] In this technical solution, the primary cooling line 15 is primarily used to recover the heated coolant and cool it down through the primary cooler 16, so that the coolant meets the storage requirements of the cooling and insulation water tank 5. The secondary cooling line 17 further cools the coolant. The main switching valve 19 controls the cooling of the coolant through the primary cooler 16 and / or the secondary cooler 18 based on the temperature and flow rate of the heated coolant entering the return water main 13, thereby ensuring the cooling effect of the coolant.

[0028] Example 5: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] The cooling stage assembly also includes: The auxiliary cooling pipe 20 has one end connected to the middle of the secondary cooling pipe 17 and a secondary cooler 21 provided at the other end; wherein the inlet end of the secondary cooler 21 is connected to the other end of the auxiliary cooling pipe 20, and the outlet end is connected to the cooling and insulation water tank 5 through a pipe; The secondary switching valve 22 is provided at the connection between the secondary cooling line 20 and the secondary cooling line 17; it is used to control the connection between one end of the secondary cooling line 17 and the other end of the secondary cooling line 17 or the connection between the other end of the secondary cooling line 17 and the secondary cooling line 20 at the same time; The auxiliary cooling pipeline 23 has one end connected to the middle of the auxiliary cooling pipeline 20 and an auxiliary cooler 24 provided at the other end; wherein the inlet end of the auxiliary cooler 24 is connected to the other end of the auxiliary cooling pipeline 23, and the outlet end is connected to the cooling and heat preservation water tank 5 through a pipeline; The auxiliary switching valve 25 is arranged at the connection between the auxiliary cooling line 23 and the auxiliary cooling line 20; it is used to control one end of the auxiliary cooling line 20 to be connected to the other end of the auxiliary cooling line 20, or to be connected to the other end of the auxiliary cooling line 20 and the auxiliary cooling line 23 at the same time.

[0030] In this technical solution, the provision of the secondary cooling line 20 allows the coolant to be further diverted through the secondary cooler 21 when the coolant temperature cannot be maintained even with the combined efforts of the primary cooler 16 and the secondary cooler 18 due to high flow. This reduces the flow of coolant entering the primary cooler 16 and the secondary cooler 18, thereby ensuring effective cooling of the coolant. The provision of the secondary switching valve 22 facilitates control of the coolant flow direction, facilitating the coolant's entry into the secondary cooling line 20.

[0031] The auxiliary cooling line 23 further cooperates with the main cooling line 15, the secondary cooling line 17 and the auxiliary cooling line 20 to cool down the heated coolant, thereby ensuring that the coolant can be cooled down even when the coolant flow is too large. The setting of the auxiliary switching valve 25 can facilitate the coolant to enter the auxiliary cooling line 23.

[0032] Example 6: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] The main cooler 16, the secondary cooler 18, the auxiliary cooler 21 and the auxiliary cooler 24 each include: The cooling housing 100 has a shell-like structure; There are several cooling dispersion pipes, which are evenly distributed in the cooling housing 100; A plurality of internal flow limiting branches 101 are respectively arranged in each cooling dispersion pipe, and the cooling dispersion pipes are extended at both ends; One end of a plurality of internal flow limiting branches 101 is connected to a refrigerant inlet pipe 101a, and the other end is connected to a refrigerant outlet pipe 101b; one end of a plurality of cooling dispersion pipes is connected to a cooling liquid inlet pipe 106, and the other end is connected to a cooling liquid outlet pipe 107; The cooler cools down the heated coolant in the cooling dispersion pipe by water cooling or air cooling.

[0034] In this technical solution, if the cooler is water-cooled, a cooling water inlet is provided at the lower portion of one side of the cooling shell 100, and a cooling water outlet is provided at the upper portion of the other side. The cooling shell 100 is generally closed, and the water used for water cooling can come from a cooling water tower or municipal water. The water after heat exchange is then used in production facilities that require heating water. If the cooler is air-cooled, one end of the cooling shell 100 has a slot connected to the interior of the cooling shell 100, and a cooling fan is provided in the slot. The other end is provided with a grille for air circulation. The cooling fan and the grille cooperate to allow the cooler air flow channel to dissipate heat and cool the internal flow limiting branch pipe 101.

[0035] The cooling dispersion pipe is designed to carry heated coolant. As the coolant passes through the pipe, it exchanges heat with the cooling water or air flowing within the cooling housing 100, thereby achieving a cooling effect. To ensure effective cooling and heat dissipation, the cooling dispersion pipe can be made of a copper alloy or other metal alloy with high thermal conductivity. The cooling dispersion pipe is vertically arranged, with heated coolant entering from the bottom and exiting from the top.

[0036] The inner flow limiting branch 101 can also be made of copper alloy or other alloys or metal materials with high thermal conductivity. The provision of the inner flow limiting branch 101 can reduce the cross-sectional area of the cooling dispersion pipe, allowing the heated coolant entering the cooling dispersion pipe to be evenly distributed near the wall of the cooling dispersion pipe, thereby facilitating the cooling of the coolant. At the same time, by transporting the refrigerant medium into the inner flow limiting branch 101, the coolant is further cooled in the cooling dispersion pipe, ensuring a good cooling effect on the coolant when the temperature of the coolant discharged from the casting mechanism is too high. The circulation of the refrigerant into the inner flow limiting branch 101 requires the cooperation of components such as a compressor and a condenser to ensure the temperature of the refrigerant transport.

[0037] Example 7: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] The cooling dispersion pipe includes: A plurality of dispersed branch pipes 102 are coaxially arranged and equidistantly distributed; Several cooling dispersion members are respectively arranged between two adjacent end dispersion branches 102 and are respectively connected to the end dispersion branches 102 on both sides; the dispersion branches 102 and the cooling dispersion members are connected and fixed by welding or other feasible methods; The cooling dispersion components include: The cooling fin 103 is a thin sheet structure with a plurality of evenly distributed dispersed holes 104 and a through hole 108 for the internal flow limiting branch 101 to pass through and to seal with the internal flow limiting branch 101. Two cooling dispersion plates 105 are respectively arranged on the two side end faces of the cooling fin 103, and cooling diffusion channels are formed thereon. The cooling diffusion channel on one side end face of the cooling fin 103 is connected to the cooling diffusion channel on the other side end face through the dispersion hole 104; the cooling dispersion plate 105 and the cooling fin 103 are connected and fixed by welding or other feasible methods.

[0039] In this technical solution, the arrangement of the dispersion branch pipes 102 allows the heated coolant to pass smoothly through the various cooling and dispersing elements, thereby ensuring a good cooling effect on the heated coolant. The outer ends of the dispersion branch pipes 102 at both ends of the cooling and dispersing pipes are sealed to prevent leakage of the coolant. The cooling fins 103 in the cooling and dispersing elements are used to increase the contact area of the cooling and dispersing elements. The heated coolant entering the cooling and dispersing disc 105 dissipates heat through contact with the cooling and dispersing disc 105 and the cooling fins 103, ensuring a cooling effect on the coolant.

[0040] Example 8: This embodiment provides a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] The cooling and dispersing disk 105 comprises: The centralizing portion 105a is located in the middle of the end surface of the cooling fin 103 and is in the shape of an arc-top shell. A centralizing cavity 105b is formed therein, and the centralizing cavity 105b is connected to the dispersed branch pipe 102 at the end thereof. A plurality of dispersed portions 105c are radially and evenly distributed on the outer edge of the concentrated portion 105a, in the shape of a long shell, one end of which is connected to the concentrated portion 105a, and a dispersed groove 105d is formed therein, and the dispersed groove 105d is connected to the concentrated cavity 105b; A plurality of outer diffusion portions 105e are formed at the other end of each dispersion portion 105c and cover a dispersion hole 104. A diffusion cavity 105f is formed therein. The diffusion cavity 105f is connected to the dispersion groove 105d and the dispersion hole 104. The central cavity 105b, the dispersion groove 105d and the diffusion cavity 105f are connected to form a cooling diffusion channel.

[0042] In the present technical solution, the concentrated portion 105a of the arc-top shell structure is used to reduce the overall thickness or depth of the coolant; the dispersed portion 105c can concentrate or disperse the incoming coolant, and the outer diffuser 105e can receive the coolant in the cooling dispersion disk 105 on both sides of the cooling fin 103; the heated coolant entering the cooling dispersion member is first concentrated in the concentrated portion 105a of the cooling dispersion disk 105 at one end of the cooling fin 103, and then diffuses to the periphery of the concentrated portion 105a through the dispersed portion 105c, and then enters the outer diffuser 105e, and finally passes through the outer diffuser 105e. 5e enters the dispersion hole 104, passes through the dispersion hole 104 and enters the outer diffusion portion 105e of the cooling dispersion disk 105 at the other end of the cooling fin 103, then passes through the outer diffusion portion 105e and enters the corresponding dispersion portion 105c. Finally, it passes through the dispersion portion 105c and is concentrated at the concentration portion 105a of the cooling dispersion disk 105 at the other end of the cooling fin 103, thereby completing the flow pattern 3 of the coolant from concentration to dispersion and then to concentration. This flow pattern also achieves sufficient cooling of the coolant, thereby ensuring that the coolant temperature can meet the requirements of the cooling and insulation water tank 5. The coolant entering the cooling dispersion element and contacting the cooling dispersion disk 105 and the cooling fin 103 on both sides further increases the contact area for heat exchange and heat dissipation, thereby ensuring the cooling effect.

[0043] Example 9: This embodiment provides a control method for a metal component casting system, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] The operation of the casting system is controlled by the controller programming, and the casting system is equipped with a temperature compensation sensor; The control methods of the casting system include: S1, obtain the total cooling water temperature T discharged from the casting mechanism in real time when the system is running 时 and flow Q 时 And the water temperature T of the coolant in the cooling and heat preservation water tank 5 冷 demand, and obtain the temperature T through the temperature compensation sensor 外 , according to T 外 With T 冷 Establish temperature difference correction coefficient T 补 ; S2, the water temperature T 时 +T 补 and T 阈 For comparison, the flow Q 时 With Q 阈 For comparison, according to T 时 +T 补 and T 阈 and Q 时 and Q 阈The cooling operation of the cooling stage components can be controlled in real time based on the situation.

[0046] When the cooler adopts air cooling, the temperature compensation sensor is used to detect the temperature of the environment in which the cooling grading component is located; when the cooler adopts water cooling, the temperature compensation sensor is used to detect the temperature of the cooling water entering the cooler.

[0047] In S1, according to T 外 With T 冷 Establish temperature difference correction coefficient T 补 , if the temperature T 外 Greater than water temperature T 冷 Time T 补 Is a positive number, if the temperature T 外 Less than water temperature T 冷 Time T 补 is a negative number; through T 时 +T 补 Correcting the temperature can improve the cooling effect and efficiency.
