Description
Technical Field
[0001] The present invention relates to the technical field of chassis moulds, and in particular to a chassis mould for high-precision chassis processing. Background Art
[0002] In the field of high-precision chassis processing, the cooling system performance of the chassis mold is crucial. Traditional high-precision chassis processing mold cooling methods have many drawbacks, which seriously affect production efficiency and product quality.
[0003] Traditional molds often use circular cooling channels, but this design is inefficient and prone to localized overheating. This not only shortens the mold's service life but also causes quality issues like deformation and dimensional deviation in the chassis. Furthermore, to achieve the desired cooling effect, the cooling time must be extended, typically by 20%-30%, significantly reducing production efficiency and increasing costs.
[0004] Furthermore, when the waterway becomes clogged, cleaning it is a tedious task. Due to the structural design of traditional cooling systems, clearing the blockage requires complete disassembly, which is not only time-consuming and labor-intensive, but can also damage the mold during disassembly and installation, further increasing repair costs and downtime. Therefore, we have proposed a chassis mold based on high-precision chassis processing to solve the above problems. Summary of the Invention

[0013] Preferably, connection holes are provided at the four corners of the upper end of the lower protective shell.
[0014] In the present invention, when dissipating heat:
[0015] 1. Coolant input: The coolant enters from the main coolant input pipeline, passes through the installation port, joint and hose, passes through the fixed pipe, and the flow is controlled by the first solenoid valve and flows into the spiral cold water pipe;
[0016] 2. Heat absorption and temperature monitoring: Inside the spiral cold water pipe, the graphene heat absorber absorbs the heat generated by the mold.

The temperature sensor transmits the data to the cloud via a wireless module.
[0017] 3. Flow adjustment: When the temperature sensor detects a local overheating area (temperature difference > 5°C), the control system automatically adjusts the first and second solenoid valves of the corresponding flow channel after receiving data from the cloud, increasing the coolant flow to quickly reduce the temperature of the overheating area;

[0025] 4. The system has preset thresholds. When the pressure is abnormal or the water channel is blocked, the machine will automatically stop and send an alarm message. This can timely detect and deal with problems in the production process, avoid product quality problems caused by mold failure, reduce the scrap rate by more than 50%, and reduce production costs.
[0026] 5. Easy to disassemble and install. When cleaning the waterway blockage, there is no need to disassemble the entire system. Only the corresponding modules need to be disassembled and installed, which saves maintenance time and cost.
[0027] 6. The graphene heat-absorbing block in the spiral cold water pipe can quickly absorb heat, and the honeycomb heat dissipation structure at the lower end of the lower protective shell further enhances the heat dissipation effect, ensures the cooling performance of the coolant, and improves the stability of the entire cooling system;

DETAILED DESCRIPTION
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0035] Reference Figure 1-4 A chassis mold for high-precision chassis processing includes a lower protective shell 11. Four circular heat dissipation chambers 4 are installed at equal intervals in the lower protective shell 11. The spacing between the four circular heat dissipation chambers 4 fully considers the uniformity of heat distribution inside the mold, can cover the heating area of the mold to the greatest extent, and ensure the comprehensiveness of the heat dissipation effect. The circular heat dissipation chambers 4 provide independent spaces for the flow and heat dissipation of coolant, which helps to improve the heat dissipation efficiency.
[0036] A spiral cold water pipe 5 is installed in the circular heat dissipation chamber 4. A support column 8 is detachably installed in the spiral cold water pipe 5. A graphene heat absorption block 9 is sleeved on the support column 8, and the graphene heat absorption block 9 is located in the spiral cold water pipe 5. When the coolant flows in the spiral cold water pipe 5, turbulence is formed. The coolant in the turbulent state can more fully contact the pipe wall, thereby more efficiently absorbing the heat generated by the mold. At the same time, the spiral structure can also slow down the flow rate of the coolant, prolong the residence time of the coolant in the pipe, and further improve the heat dissipation effect.
[0037] A pressure sensor and temperature sensor are installed within the spiral cooling water pipe 5. Two main coolant input lines 3 are installed on one side of the lower protective shell 11. One main coolant input line 3 on the same side is connected to the two spiral cooling water pipes 5 on the same side. One end of the spiral cooling water pipe 5 is connected to an output line. A flow guide structure is installed at the lower end of the lower protective shell 11. The sensors use high-precision components, featuring fast response and accurate measurement. The pressure sensor can promptly detect pressure changes during the coolant flow process and determine whether there are problems such as water blockage. The temperature sensor can accurately measure the coolant temperature, providing accurate data support for subsequent flow adjustments.
[0038] The guide structure includes an opening provided at the lower end of the lower protective shell 11, with a guide plate 17 installed on the side wall of the opening, and a honeycomb heat dissipation structure 16 installed on the guide plate 17. Four threaded blind holes 18 are provided on the honeycomb heat dissipation structure 16 at equal intervals. The honeycomb heat dissipation structure 16 has a large surface area, which can increase the contact area between the coolant and the air, thereby improving the heat dissipation efficiency. At the same time, the connection method between the support column 8 and the threaded blind hole 18 not only ensures the stability of the structure, but also facilitates the disassembly and replacement of components.
[0039] The lower end of the support column 8 is provided with a plurality of external threads 14 at equal intervals around the periphery. The lower ends of the four support columns 8 are respectively screwed into the four threaded blind holes 18 through the external threads 14. The graphene heat absorbing block 9 is arranged in a cylindrical shape. The middle part of the graphene heat absorbing block 9 is provided with a mounting hole 15. A support column 8 on the same side passes through a mounting hole 15 on the same side. The support column 8 plays the role of fixing the graphene heat absorbing block 9. Graphene has excellent thermal conductivity and can quickly absorb the heat generated by the mold and transfer it to the coolant, greatly improving the heat dissipation efficiency.
[0040] The upper end of the spiral cold water pipe 5 is connected to a fixed pipe 10, on which a first solenoid valve 2 is installed. One end of the fixed pipe 10 is connected to a hose 6, and one end of the hose 6 is connected to a connector 7. Two mounting ports 1 are provided on one side of the main coolant input pipeline 3, and the two mounting ports 1 correspond to the two connectors 7 respectively. The setting of the first solenoid valve 2 enables the flow rate of the coolant to be precisely controlled. By adjusting the opening of the first solenoid valve 2, the flow rate of the coolant can be flexibly adjusted according to the heating conditions of different parts of the mold to achieve personalized heat dissipation requirements. The design of the hose 6 and the connector 7 facilitates the connection and disassembly of the pipeline, and is convenient for the maintenance and repair of the mold.
[0041] The output pipeline includes two main coolant output pipelines 12 installed on one side of the lower end of the lower protective shell 11. The lower ends of the two spiral cold water pipes 5 on the same side are connected to the main coolant output pipeline 12 through a connecting pipe. A second solenoid valve is installed on the connecting pipe. The second solenoid valve is also used to accurately control the output flow of the coolant. After the coolant absorbs heat, by reasonably adjusting the opening of the second solenoid valve, it can be ensured that the coolant can flow out of the mold in a timely and stable manner, thereby avoiding heat accumulation in the mold;
[0042] In the present invention, when dissipating heat:
[0043] 1. Coolant input: The coolant enters from the main coolant input pipe 3, passes through the installation port 1, the connector 7 and the hose 6, passes through the fixed pipe 10, and the flow is controlled by the first solenoid valve 2, and flows into the spiral cold water pipe 5;
[0044] 2. Heat absorption and temperature monitoring: Inside the spiral cold water pipe 5, the graphene heat absorption block 9 absorbs the heat generated by the mold. At the same time, the pressure sensor and temperature sensor monitor the pressure and temperature inside the spiral cold water pipe 5 in real time. The temperature sensor transmits the data to the cloud via a wireless module.
[0045] 3. Flow adjustment: When the temperature sensor detects that the temperature difference in the local overheating area is greater than 5°C, the control system automatically adjusts the first solenoid valve 2 and the second solenoid valve of the corresponding flow channel after receiving the cloud data, increasing the coolant flow to quickly reduce the temperature of the overheating area;
[0046] 4. Coolant output: After absorbing heat, the coolant passes through the connecting pipe and is controlled by the second solenoid valve to flow out from the main coolant output pipeline 12;
[0047] 5. Heat dissipation: The guide plate 17 at the lower end of the lower protective shell 11 guides the coolant to flow, and the coolant is fully dissipated through the honeycomb heat dissipation structure 16, preparing for the recycling of the coolant;
[0048] 6. Abnormal alarm: The pressure sensor monitors the cavity pressure in real time. When the pressure is abnormal or the water channel is blocked, the system detects that the pressure and temperature data exceed the preset threshold, automatically shuts down and sends an alarm message.
[0049] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
