[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This disclosure provides a mold 0, referring to... Figure 1 It includes a first mold base 01, a second mold base 02, and a temperature regulating component 03; The first mold base 01 and the second mold base 02 are used to cooperate with each other to perform shaping processing on the workpiece; The temperature regulating component 03 is connected to the first mold base 01 and / or the second mold base 02, and is used to regulate the temperature of the connected mold bases.

[0023] The temperature regulating component 03 is connected to the first mold base 01 and / or the second mold base 02. During the molding process, the temperature regulating component 03 can regulate the temperature of the connected mold base, reduce the temperature difference between the workpiece and the mold base, reduce the rate of temperature change in different parts of the workpiece, make the workpiece cool more uniformly in the cavity, make the volume change in different parts of the workpiece tend to be consistent, reduce the residual stress generated inside the workpiece, reduce the local deformation caused by the release of residual stress after demolding, reduce the risk of internal voids and fractures after demolding, and improve the molding quality of the workpiece.

[0024] In one possible implementation, refer to Figure 2 The first mold base 01 and / or the second mold base 02 have a medium space 04; The medium space 04 is connected to the temperature regulation component 03 and is used to supply the flow of heat exchange medium.

[0025] Before or during molding, the temperature control component 03 is activated, outputting the heat exchange medium into the medium space 04. The heat exchange medium flows within the medium space 04, exchanging heat with the first mold base 01 and / or the second mold base 02 during this flow. When the temperature of the heat exchange medium is higher than the temperature of the mold base body, the heat exchange medium releases heat to the mold base body, causing the mold base to heat up; when the temperature of the heat exchange medium is lower than the temperature of the mold base body, the mold base body releases heat to the heat exchange medium, causing the mold base to cool down. After heat exchange, the heat exchange medium flows out of the medium space 04. The temperature control component 03 continuously supplies heat exchange medium into the medium space 04, ensuring that the temperature of the mold base body is stably maintained within a preset range.

[0026] The medium space 04 is located inside the first mold base 01 and / or the second mold base 02. Compared to placing the heating or cooling element on the outer surface of the mold base, where heat needs to be conducted from the outside to the inside of the mold base body to the cavity, the heat exchange position extends deep into the internal area of ​​the mold base. The heat conduction path between the heat exchange position and the mold base cavity is shortened, and the heat exchange medium directly exchanges heat with the mold base body inside the mold base body. The cavity area responds quickly to receiving or releasing heat, and the temperature regulation component 03 can effectively regulate the temperature of the mold base to the surface of the mold base cavity. The heat exchange medium flows into the medium space 04. Heat exchange occurs between the workpiece and the mold base body along each path, resulting in smaller temperature differences at various points on the mold base body and a more uniform temperature distribution. This reduces the temperature differences between the workpiece and the mold base body at different locations within the cavity, improves the cooling uniformity of different parts of the workpiece, and reduces stress concentration between different parts of the workpiece. Furthermore, the temperature regulation component 03 is located outside the mold base, facilitating inspection, maintenance, repair, and parts replacement by operators without disassembling the mold base body. This improves the convenience of maintenance operations and reduces downtime required for maintenance.

[0027] In some examples, the first mold base 01 and / or the second mold base 02 are provided with multiple heat exchange channels, which are located close to the cavity and are interconnected to form a medium space 04. Each heat exchange channel is connected to the temperature regulating component 03.

[0028] Multiple heat exchange channels are positioned close to the cavity, concentrating the heat exchange of the heat exchange medium within the mold base body in the region near the cavity surface. This further reduces the thickness of the mold base body required to traverse from the heat exchange location to the cavity surface. These multiple heat exchange channels are arranged at different locations within the mold base near the cavity, allowing the heat exchange medium to exchange heat with the mold base body simultaneously at multiple locations. The rate at which heat is received or released at various locations on the cavity surface tends to be consistent, reducing the temperature difference on the cavity surface at any given time. This results in more similar mold base temperatures at different locations within the cavity, reducing the cooling rate differences between different locations on the workpiece, decreasing residual stress between different parts of the workpiece, and lowering the risk of voids and fractures within the workpiece. Furthermore, the interconnected heat exchange channels allow the heat exchange medium to circulate freely between them, preventing excessively high local heat loads and resulting in locally high or low temperatures in the heat exchange medium. The temperature distribution of the heat exchange medium within the multiple heat exchange channels is more consistent, and the intensity of heat exchange received by different areas of the cavity is more uniform.

[0029] In one possible implementation, refer to Figure 3 The temperature control component 03 includes a liquid storage tank 031, a heat exchanger 032, and a conveying component 033; The liquid storage tank 031, heat exchanger 032, conveying component 033 and medium space 04 are connected in sequence to form a circulation loop.

[0030] Before or during molding, the conveyor 033 is activated and drives the heat exchange medium to flow along the circulation loop. The heat exchange medium, after being output from the storage tank 031, passes sequentially through the heat exchanger 032 and the conveyor 033, entering the medium space 04 within the first mold base 01 and / or the second mold base 02. As the heat exchange medium flows through the heat exchanger 032, it exchanges heat with the heat exchanger 032. As it flows through the conveyor 033, it continues to be conveyed along the circulation loop under the drive of the conveyor 033. After entering the medium space 04, the heat exchange medium exchanges heat with the mold base body, regulating the temperature of the mold base. The heat exchange medium, after exchanging heat with the mold base body, flows out of the medium space 04 and returns to the storage tank 031 along the circulation loop, completing one cycle. Driven by the conveyor 033, the heat exchange medium circulates repeatedly in the loop along the path of the storage tank 031, heat exchanger 032, conveyor 033, and medium space 04. The heat exchanger 032 continuously regulates the temperature of the heat exchange medium in the loop, and the temperature of the heat exchange medium in the loop is stably maintained near the preset temperature. The mold base body continuously exchanges heat with the temperature-stable heat exchange medium, and the temperature is stably maintained within the preset range, forming a closed temperature control system. Compared with the open temperature control method, the heat exchange medium in the loop repeatedly passes through the heat exchanger 032. The temperature adjustment range of the heat exchanger 032 on the heat exchange medium is small in each cycle. The heat exchanger 032 does not need to adjust the heat exchange medium from the initial temperature to the target temperature in a single pass. The workload of the heat exchanger 032 is reduced, and the temperature regulation stability is high.

[0031] During the operation of the temperature control component 03, the heat exchange medium circulates repeatedly between the storage tank 031 and the mold base along the circulation loop. The heat exchange medium flowing out of the mold base returns to the storage tank 031 through the circulation loop and is transported back to the mold base to participate in the next round of heat exchange. The temperature control component 03 does not need to continuously replenish new heat exchange medium during operation, thus reducing the overall consumption of heat exchange medium. Furthermore, the heat exchange medium flows within the circulation loop without being discharged or coming into contact with the external environment, preventing the heat exchange medium from being lost or deteriorated due to exposure, volatilization, or contamination during use. This ensures the operational stability of the temperature control component 03 and the cleanliness of the medium.

[0032] In one example, the inlet of the storage tank 031 is located above the outlet of the storage tank 031.

[0033] Before settling to the height of the outlet, the returned heat exchange medium needs to pass through a top-to-bottom flow path in the storage tank 031. This flow path provides time for the returned heat exchange medium to mix naturally with the heat exchange medium originally stored in the storage tank 031. The temperature of the heat exchange medium extracted by the conveyor 033 is closer to the overall average temperature of the heat exchange medium in the storage tank 031, thus improving the stability of the temperature of the heat exchange medium in the circulation loop.

[0034] In one example, the heat exchanger 032 can be any type of shell-and-tube heat exchanger, finned tube heat exchanger, etc.; this disclosure does not limit the specific form of the heat exchanger 032, and the heat exchanger 032 can also be other components that can heat or cool the heat exchange medium to regulate the temperature of the heat exchange medium.

[0035] In one example, the conveying component 033 can be any of a gear pump, a plunger pump, etc.; this disclosure does not limit the specific form of the conveying component 033, and the conveying component 033 can also be other components that can drive the heat exchange medium to flow along the circulation loop.

[0036] In one possible implementation, refer to Figure 4 The temperature regulating component 03 also includes a first unidirectional conductor 034 and a second unidirectional conductor 035; The first unidirectional guiding element 034 is connected between the conveying element 033 and the medium space 04; The second unidirectional guide 035 is connected between the medium space 04 and the liquid storage tank 031.

[0037] A first unidirectional flow element 034 connects the conveying element 033 and the medium space 04, and a second unidirectional flow element 035 connects the medium space 04 and the storage tank 031. The first unidirectional flow element 034 only allows the heat exchange medium to flow from the conveying element 033 to the medium space 04 and prevents the heat exchange medium in the medium space 04 from flowing back to the conveying element 033 along the original path. The second unidirectional flow element 035 only allows the heat exchange medium to flow from the medium space 04 to the storage tank 031 and prevents the heat exchange medium in the storage tank 031 from flowing back to the medium space 04 along the original path. The first unidirectional flow element 034 and the second unidirectional flow element 035 work together to limit the flow direction of the heat exchange medium in the circulation loop to a single direction along the storage tank 031, heat exchange element 032, conveying element 033, medium space 04, and storage tank 031.

[0038] When the output pressure of the conveyor 033 decreases or stops momentarily due to shutdown or power failure, the heat exchange medium in the circulation loop will not flow in reverse along the original path due to pressure difference changes. The medium space 04 remains full of heat exchange medium during the period when the conveyor 033 stops. During this period, the mold base body can still exchange heat by contacting the heat exchange medium remaining in the medium space 04. During the process from the momentary stop of the conveyor 033 to the resumption of normal operation, the temperature change of the mold base body is small. After the conveyor 033 resumes operation, the temperature regulation component 03 does not need to go through multiple cycles to restore the preset temperature. The temperature regulation component 03 has high temperature regulation efficiency for the mold base.

[0039] In some examples, the first unidirectional guide 034 is fixed to the first mold base 01 and / or the second mold base 02 and is located at the liquid inlet end of the medium space 04; the second unidirectional guide 035 is fixed to the first mold base 01 and / or the second mold base 02 and is located at the liquid outlet end of the medium space 04.

[0040] It should be noted that during normal operation of the conveyor 033, the conveyor 033 applies driving force to the heat exchange medium flowing through it by means of impeller rotation, causing the pressure of the heat exchange medium at the output end of the conveyor 033 to increase and the pressure at the input end of the conveyor 033 to decrease. The pressure difference formed between the downstream of the circulation loop (the path of the heat exchange medium from the output end of the conveyor 033 to the return end of the storage tank 031) and the upstream of the circulation loop (the path of the heat exchange medium from the outlet end of the storage tank 031 to the input end of the conveyor 033) due to the work done by the conveyor 033 is actively maintained by the continuous work of the conveyor 033. This pressure difference is both the driving force for the heat exchange medium... The unidirectional flow of the heat exchange medium along the circulation loop also causes the downstream side of the circulation loop to store higher pressure potential energy relative to the upstream side. When the conveyor 033 stops working, it no longer does work on the heat exchange medium. The pressure difference between the upstream and downstream of the circulation loop loses its active power source. The high pressure state accumulated on the downstream side of the circulation loop begins to release the stored pressure potential energy to the low pressure area on the upstream side. During the release process, the heat exchange medium flows from the downstream high pressure area to the upstream low pressure area. This flow direction is opposite to the flow direction of the heat exchange medium when the conveyor 033 is working normally. The heat exchange medium in the circulation loop tends to flow in the opposite direction to the original flow direction.

[0041] Therefore, when the conveyor 033 stops or loses power, the tendency of the heat exchange medium in the medium space 04 to flow out in reverse along the inlet end is blocked at the inlet end of the medium space 04 by the first one-way guide 034, and the tendency of the heat exchange medium in the storage tank 031 to flow back into the medium space 04 is directly blocked at the outlet end of the medium space 04 by the second one-way guide 035. The locations where the backflow of the heat exchange medium is blocked are at the inlet and outlet ends of the medium space 04, rather than at other locations in the circulation loop. The medium space 04 remains full of heat exchange medium, and the mold base body can still effectively exchange heat with the heat exchange medium in the medium space 04.

[0042] In some examples, the first unidirectional flow element 034 and the second unidirectional flow element 035 can be one-way valves. This disclosure does not limit the specific form of the first unidirectional flow element 034 and the second unidirectional flow element 035. The first unidirectional flow element 034 and the second unidirectional flow element 035 can also be other components that can realize the function of allowing the heat exchange medium to pass in only one direction and preventing the heat exchange medium from passing in the opposite direction.

[0043] In some examples, the temperature regulating component 03 is mounted on the first mold base 01 and / or the second mold base 02.

[0044] The temperature regulating component 03 is installed on the first mold base 01 and / or the second mold base 02. When the mold 0 performs the opening and closing action, the first mold base 01 and the second mold base 02 move relative to each other. The temperature regulating component 03 installed on the mold base moves synchronously with its respective mold base. There is no relative displacement between the temperature regulating component 03 and its mold base. The pipeline structure remains relatively stationary during the opening and closing process and does not undergo bending, stretching, torsion or other deformations. The pipeline structure does not suffer fatigue damage or sealing wear due to the high-frequency action of opening and closing the mold, ensuring the sealing and stability of the circulation loop and reducing the risk of heat exchange medium leakage from the pipeline structure.

[0045] Therefore, the selection of piping structure is no longer limited by the relative movement of mold opening and closing. Flexible or rigid pipes can be freely selected based on factors such as the pressure resistance requirements of the circulation loop, the characteristics of the heat exchange medium, and spatial arrangement conditions. When the working pressure of the circulation loop is low and the piping needs to follow the space around the mold, flexible pipes can be used to improve the flexibility of the arrangement. When the working pressure of the circulation loop is high and it needs to withstand the pressure load of the heat exchange medium for a long time, rigid pipes can be used to improve the pressure resistance and sealing reliability. The freedom of choice in piping structure is increased, and suitable piping types can be selected for different application scenarios.

[0046] In some examples, the temperature regulating component 03 also includes a heat pipe housed within a medium space 04, with the outer wall of the heat pipe fitting against the inner wall of the medium space 04. One end of the heat pipe is connected to a unidirectional conductor, and the other end is connected to a second unidirectional conductor 035.

[0047] During the molding process, the heat exchange medium enters one end of the heat pipe from the end of the first unidirectional guide 034, flows inside the heat pipe, and finally flows out from the other end of the heat pipe to the second unidirectional guide 035. During the entire flow process, the heat exchange medium only flows inside the heat pipe and does not enter the area outside the heat pipe in the medium space 04. The heat exchange medium exchanges heat with the heat pipe. Since the outer wall of the heat pipe is in contact with the inner wall of the medium space 04, the heat on the heat pipe is further transferred to the mold base body. The heat exchange medium and the mold base body are completely separated by the pipe wall of the heat pipe in physical space and do not come into direct contact.

[0048] The heat exchange medium and the mold base body are separated by the tube wall of the heat-conducting pipe and do not come into direct contact. The heat exchange medium will not seep into and contaminate the metal structure of the mold base body, and the mold base body is protected from corrosion, scaling and other damage that may be caused by long-term contact with the heat exchange medium. The heat-conducting pipe is housed as an independent component in the medium space 04. When the heat-conducting pipe has problems such as scaling or blockage on the inner wall, the heat-conducting pipe can be removed from the medium space 04 and replaced without machining or disassembling the mold base body, which is convenient for maintenance and extends the service life of the mold base.

[0049] In one possible implementation, refer to Figure 5 The temperature regulating component 03 includes at least two first unidirectional conduction elements 034; Each of the first unidirectional conductive elements 034 is connected to a different position in the medium space (04).

[0050] The first unidirectional guide member 034 is configured as at least two and is connected to different positions of the medium space 04 respectively. The heat exchange medium enters the medium space 04 from different positions through the first unidirectional guide member 034. The difference in distance from each position in the medium space 04 to the nearest heat exchange medium entry point is reduced. Different positions on the mold base body receive heat exchange simultaneously, and the temperature distribution of the mold base body is more uniform. As a result, the mold base temperature that the workpiece contacts at different positions in the cavity is closer, the difference in cooling rate at different positions of the workpiece is reduced, the residual stress is reduced, the risk of internal voids and fractures after demolding is reduced, and the forming quality of the workpiece is improved.

[0051] Compared to a single first unidirectional guide component 034, the parallel connection of multiple first unidirectional guide components 034 increases the total flow cross-section, increases the total amount of heat exchange medium entering the medium space 04 per unit time, increases the heat exchange between the mold base body and the heat exchange medium per unit time, and improves the temperature regulation effect; the flow rate borne by a single first unidirectional guide component 034 is reduced, the flow velocity of the heat exchange medium in a single first unidirectional guide component 034 is reduced, the flow resistance is reduced, and the loss of driving force of the conveying component 033 is reduced.

[0052] In one possible implementation, refer to Figure 6 The temperature regulation component 03 also includes a mixing component 036; The mixing component 036 is connected to the liquid storage tank 031 and is used to mix the heat exchange medium in the liquid storage tank 031.

[0053] During the repeated circulation of the loop, the heat exchange medium returning from the mold base to the storage tank 031 deviates from the preset temperature set by the heat exchange component 032 because it has just undergone heat exchange with the mold base body. After the returned heat exchange medium enters the storage tank 031, it is quickly mixed with the heat exchange medium originally stored in the storage tank 031 under the mixing action of the mixing component 036, and the temperature distribution of the heat exchange medium in the storage tank 031 tends to be uniform. The conveying component 033 continuously draws heat exchange medium from the storage tank 031 and conveys it to the heat exchange component 032. The drawn heat exchange medium is in a mixed state with uniform temperature.

[0054] The mixing component 036 mixes the heat exchange medium in the storage tank 031, preventing temperature stratification caused by the temperature difference between the new returned medium and the original medium in the storage tank 031, and ensuring uniform temperature of the heat exchange medium in the storage tank 031. The conveying component 033 draws from the storage tank 031 and conveys the heat exchange medium to the heat exchange component 032, resulting in a relatively stable temperature state. The temperature regulation effect of the heat exchange component 032 on the heat exchange medium is more stable, and the stability of the temperature of the heat exchange medium received by the mold base body is improved.

[0055] In addition, when the heat exchange medium is a multi-component medium, the mixing component 036 keeps the components uniformly distributed in the storage tank 031, avoiding component stratification caused by the heat exchange medium being left to stand in the storage tank 031. The compositional uniformity of the heat exchange medium in the storage tank 031 is maintained, and the heat exchange performance of the heat exchange medium remains stable during operation.

[0056] In one possible implementation, refer to Figure 6 , 7 The mixing component 036 includes a first driving component 0361 and a stirring component 0362; The first driving component 0361 is connected to the stirring component 0362, which is located inside the storage tank 031.

[0057] In one possible implementation, refer to Figure 6 The stirring component 0362 includes a stirring rod 03621 and a stirring blade 03622; The stirring rod 03621 is connected to the first driving component 0361; The stirring blade 03622 is fixed to the stirring rod 03621.

[0058] In some examples, the agitator 0362 includes a plurality of agitator blades 03622, which are spaced apart along the agitator rod 03621.

[0059] Multiple stirring blades 03622 apply stirring action to the heat exchange medium at different positions along the extension direction of the stirring rod 03621. The heat exchange medium entering the storage tank 031 and the heat exchange medium to be exited from the storage tank 031 can be stirred by the stirring blades 03622 at the same time. The mixing of the stirring element 0362 within the entire range of the storage tank 031 is more thorough, and the overall temperature uniformity and composition uniformity of the heat exchange medium in the storage tank 031 are further improved.

[0060] In some examples, the first drive element 0361 can be any of an electric motor, a pneumatic motor, or a hydraulic motor. This disclosure does not limit the specific form of the first drive element 0361, and the first drive element 0361 can also be other components capable of outputting rotational motion to drive the stirring rod 03621 to rotate.

[0061] In one possible implementation, the first drive member 0361 is detachably connected to the liquid storage tank 031.

[0062] When the first drive component 0361 malfunctions or requires maintenance, cleaning, or replacement, it can be removed from the storage tank 031 for separate repair or replacement. When the type of heat exchange medium or process requirements in the storage tank 031 change, or when there are different requirements for stirring power or stirring method, the detachable first drive component 0361 can be easily replaced with a first drive component 0361 with different output power or different driving method, thus improving the adaptability of the mixing component 036.

[0063] In one possible implementation, the temperature regulating component 03 is connected to both the first mold base 01 and the second mold base 02.

[0064] In some examples, mold 0 may include two temperature regulating components 03, which are respectively connected to a first mold base 01 and a second mold base 02.

[0065] Secondly, this disclosure provides a stamping device 1, referring to... Figure 8 , including the mold 0 provided by the first aspect or any possible implementation of the first aspect.

[0066] In one possible implementation, the stamping device 1 further includes a stamping support assembly 11, a synchronous drive assembly 12, and a demolding assembly 13; The stamping support assembly 11 is connected to the first mold base 01 and the second mold base 02, and is used to support the mold 0; The synchronous drive assembly 12 is connected to the stamping support assembly 11 and is connected to the first mold base 01 and the second mold base 02 for driving the first mold base 01 and the second mold base 02 to perform mold opening and closing operations. The demolding assembly 13 is connected to the first mold base 01 and is used to eject the stamped workpiece from the cavity of the first mold base 01 after stamping is completed.

[0067] In one possible implementation, refer to Figure 8 The stamping support assembly 11 includes a support base 111, a first connecting shaft 112, and a second connecting shaft 113; The first connecting shaft 112 and the second connecting shaft 113 are fixed to the support base 111; The first mold base 01 and the second mold base 02 are rotatably connected to the support base 111 via connecting shafts. The first mold base 01 and the second mold base 02 can swing between the mold closing position and the mold opening position around their respective first connecting shaft 112 and second connecting shaft 113.

[0068] In one possible implementation, refer to Figure 8 , 9 10, 11, The synchronous drive assembly 12 includes a power source 121, a transmission frame 122, a transmission slide bar 123, and a delayed mold opening component 124; The power source 121 is fixed to the support base 111, and the output end of the power source 121 is fixed to the transmission frame 122, which is used to drive the transmission frame 122 to move along the output direction of the power source 121. The transmission slide bar 123 is fixed to the end of the transmission frame 122; The second mold base 02 has two oppositely opening transmission grooves 021. The two ends of the transmission slide rod 123 are respectively inserted into the two transmission grooves 021, and the transmission slide rod 123 can slide along the transmission grooves 021. The delayed mold opening component 124 is connected between the transmission frame 122 and the first mold base 01, and is used to transmit the movement of the transmission frame 122 to the first mold base 01 in a delayed manner.

[0069] The delayed mold opening component 124 includes a transmission link 1241, a transmission column 1242, and a transmission spring 1243; One end of the transmission connecting rod 1241 is rotatably connected to the transmission frame 122, and the other end is rotatably connected to the transmission column 1242; The transmission column 1242 is connected to the first mold base 01 via the transmission spring 1243.

[0070] In some examples, the power source 121 can be any of a hydraulic cylinder, a pneumatic cylinder, an electric actuator, or a linear motor; this disclosure does not limit the specific form of the power source 121, and the power source 121 can also be other components capable of outputting linear driving force to drive the transmission frame 122 to move in the output direction.

[0071] Mold closing process: Before the molding process begins, the workpiece is placed in the cavity of the first mold base 01. Both the first mold base 01 and the second mold base 02 are in the mold opening position. The end of the transmission column 1242 abuts against the bottom of the first mold base 01. The transmission spring 1243 is compressed under the gravity of the first mold base 01. The power source 121 starts and outputs driving force. The output end of the power source 121 pushes the transmission frame 122 to move. The movement of the transmission frame 122 simultaneously drives the swing of the second mold base 02 and the first mold base 01 through two transmission paths respectively. The transmission slide rod 123 fixed to the end of the transmission frame 122 moves synchronously with the transmission frame 122 along the output direction of the power source 121. The two ends of the transmission slide rod 123 slide in the two opposite transmission grooves 021 of the second mold base 02. The transmission groove 021 converts the linear motion of the transmission slide rod 123 into the rotation of the second mold base 02 around the second connecting shaft 113 through its constraint on the transmission slide rod 123. The second mold base 02 swings towards the first mold base 01. Simultaneously, one end of the transmission link 1241 moves synchronously with the transmission frame 122, and the other end of the transmission link 1241 drives the transmission column 1242 to move away from the first mold base 01. The transmission column 1242 continues to abut against the bottom of the first mold base 01 until the first mold base 01 abuts against the support base 111. The transmission link 1241 continues to move under the drive of the power source 121. The transmission column 1242 releases its abutment against the bottom of the first mold base 01, and the compressed transmission spring 1243 gradually returns to its natural state. The transmission column 1242 continues to move along the direction away from the first mold base 01 to the preset position. At the same time, the second mold base 02 continues to swing to the mold closing position under the continuous drive of the transmission slide rod 123 and the transmission groove 021. The first mold base 01 and the second mold base 02 jointly complete the stamping and forming of the workpiece.

[0072] Mold opening process: After stamping, the power source 121 outputs driving force in the opposite direction, and the transmission frame 122 moves in the opposite direction of the output direction of the power source 121. The reverse movement of the transmission frame 122 simultaneously drives the second mold base 02 and the first mold base 01 to open and swing through two transmission paths respectively: the transmission slide rod 123 fixed at the end of the transmission frame 122 moves synchronously in the opposite direction with the transmission frame 122. The two ends of the transmission slide rod 123 slide in the opposite direction along the transmission groove 021. The transmission groove 021 converts the linear motion of the transmission slide rod 123 into the rotation of the second mold base 02 around the second connecting shaft 113 through its constraint on the transmission slide rod 123. The second mold base 02 swings in the opposite direction, away from the first mold base 01 until it reaches the mold opening position. Simultaneously, one end of the transmission link 1241 moves in the opposite direction with the transmission frame 122, while the other end of the transmission link 1241 drives the transmission column 1242 to move along the direction of the first mold base 01. Before the end of the transmission column 1242 abuts against the bottom of the first mold base 01, the transmission spring 1243 gradually enters the compressed state from its natural state to absorb part of the displacement of the transmission column 1242, until the end of the transmission column 1242 abuts against the bottom of the first mold base 01 again and continues to move along the direction of the first mold base 01. The first mold base 01 remains stationary due to its own weight pressing against the support base 111. The spring force of the transmission spring 1243 and the... The combined force of the drive column 1242 lifts the first mold base 01, causing the bottom of the first mold base 01 to detach from the support base 111. The first mold base 01 then rotates in the opposite direction around the first connecting shaft 112. Under the continuous drive of the drive link 1241, the drive column 1242 continues to move along the direction of the first mold base 01. The first mold base 01 swings under the contact of the drive column 1242 until it reaches the mold opening position. The drive spring 1243 remains under pressure. The separation process of the two mold bases proceeds sequentially in time—the second mold base 02 rotates first, and then the first mold base 01 rotates. The stamping device 1 returns to the mold opening state to prepare for the next round of forming processing.

[0073] In one possible implementation, refer to Figure 9The stamping device 1 includes at least two dies 0, which are symmetrically distributed on the support base 111. The synchronous drive assembly 12 is connected to the first die base 01 and the second die base 02 of each die 0, and is used to synchronously drive each die 0 to perform opening and closing operations.

[0074] In one possible implementation, refer to Figure 12 The demolding assembly 13 includes a second drive component 131, a screw 132, and a demolding slide plate 133; The second driving component 131 is fixed to the end face of the first mold base 01 facing away from the cavity. The power output end of the second driving component 131 is connected to the screw 132 to drive the screw 132 to rotate. The screw 132 is threadedly connected to the demolding slide plate 133. The abutment of the demolding slide plate 133 passes through the body of the first mold base 01 and extends into the cavity of the first mold base 01. The second driving component 131 can be any one of an electric motor, a pneumatic motor, or a hydraulic motor. This disclosure does not limit the specific form of the second driving component 131. The second driving component 131 can also be other components capable of outputting rotational motion to drive the screw 132 to rotate.

[0075] After the mold opening process is completed, the second drive component 131 starts and outputs rotational motion. The power output end of the second drive component 131 drives the screw 132 to rotate synchronously around its own axis. The threaded engagement between the screw 132 and the demolding slide plate 133 converts the rotational motion of the screw 132 into the linear motion of the demolding slide plate 133 along the axial direction of the screw 132. The demolding slide plate 133 moves towards the second mold base 02. The top end of the demolding slide plate 133 continuously applies an ejection force to the stamped workpiece located in the cavity of the first mold base 01. Under the action of the ejection force of the demolding slide plate 133, the workpiece is ejected upward from the cavity of the first mold base 01. Demolding is completed after the workpiece is completely separated from the inner wall of the cavity of the first mold base 01.

[0076] In one possible embodiment, the first mold base 01 and the second mold base 02 have an air injection cavity. The first mold base 01 and the second mold base 02 are provided with an air inlet and an air outlet. The air inlet and the air outlet are connected to the air injection cavity. The air inlet is connected to an external air source, and the air outlet is connected to the inner wall of the cavity of the first mold base 01 and the second mold base 02, for outputting the gas in the air injection cavity to the contact surface between the first mold base 01, the second mold base 02 and the workpiece.

[0077] After stamping is completed and before the demolding process begins, an external air source inputs compressed gas into the injection chambers inside the first mold base 01 and the second mold base 02 through air inlets opened on the first mold base 01 and the second mold base 02. After the compressed gas is collected in the injection chamber, it flows out through the air outlets opened on the inner wall of the cavity of the first mold base 01 and the second mold base 02, and enters the contact position between the workpiece and the inner wall of the cavity of the first mold base 01 and the surface of the workpiece and the second mold base 02. A gas separation layer is formed between the contact surface of the workpiece and the first mold base 01 and the second mold base 02, which overcomes the demolding resistance caused by the tight fit between the workpiece and the mold base surface, and provides low resistance conditions for the subsequent active ejection operation of the demolding component 13.

[0078] The technical effects of the embodiments provided in this disclosure include at least the following: the temperature regulating component 03 is connected to the first mold base 01 and / or the second mold base 02. During the molding process, the temperature regulating component 03 can regulate the temperature of the connected mold base, reduce the temperature difference between the mold base and the workpiece, reduce the rate of temperature change in different parts of the workpiece, make the workpiece cool more uniformly in the cavity, make the volume change in different parts of the workpiece tend to be consistent, reduce the residual stress generated inside the workpiece, reduce the risk of internal voids and fractures after demolding, and improve the molding quality of the workpiece.
