Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically a detachable forming mold with precise pressure control. Background Technology

[0002] In mold forming and processing, molds have specific contours or internal cavity shapes. Using contour shapes with cutting edges can separate the blanks according to the contour lines. Using internal cavity shapes can give the blanks corresponding three-dimensional shapes. Existing molds mostly use multi-piece splicing to separate the lower mold, but their split structure leads to the leveling and mold closing pressure control problems of integrated molds, which affect the quality of mass-produced products.

[0003] However, the detachable lower mold must have a leveling problem. The problem may be caused by the inherent tolerance of the processing and assembly of the split inserts, resulting in height differences on the parting surface after splicing, or uneven heating and pressure of each insert during the forming process, resulting in asynchronous thermal expansion and elastic deformation, and misalignment again under high temperature conditions after leveling at room temperature.

[0004] The purpose of precise leveling of the lower mold is to eliminate overflow and flash at the joints of the inserts, ensure the integrity of the texture appearance, balance the force when the mold is closed, avoid the extrusion deformation of the inserts, thereby unifying the cavity reference, reducing product warpage, retaining the advantages of quick maintenance of the split mold, and avoiding product tearing defects caused by misalignment of the core puller.

[0005] The existing mold relies entirely on the mold's unified locking and pressure control after mold closing, which cannot adapt to the differentiated expansion force in the splicing seam area. Furthermore, the upper mold is a rigid integral structure, and there is no independent reinforcement and pressure control for the splicing seam.

[0006] In summary, there is an urgent need to develop a leveling and pressure control mold to solve the problems of difficulty in leveling and inability to accurately control pressure in disassembly molds. Summary of the Invention

[0007] The technical problem to be solved by the present invention is the problem of leveling the lower mold and accurately controlling the pressure of the upper mold, and provides a detachable forming mold with accurate pressure control.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The forming mold includes an upper mold unit, a controller and a pressure control unit, a lower mold unit on one side of the upper mold unit, and a leveling unit on the lower mold unit. The upper mold unit includes the upper mold and the locking component; The lower mold unit includes the lower mold and the flattening component; The leveling unit includes mounting components and testing components; The pressure control unit includes pressure control components; The upper mold is fixedly connected to the pressure control component, the locking component and the mounting component are arranged coaxially, and the mounting component and the leveling component are fixedly connected.

[0009] Furthermore, the locking component includes a mounting block, a fixed post, a locking rod, a return spring, an electromagnet, and a top block. The mounting block is fixedly mounted on the upper mold, and the mounting block is fixedly connected to the fixed post. The fixed post is slidably connected to the locking rod, and the locking rod is fixedly connected to the electromagnet. There are two electromagnets, and the two electromagnets are connected by a return spring. The top block is fixedly mounted on the end face of the fixed post away from the mounting block.

[0010] Furthermore, the two electromagnets exhibit opposite polarities when energized.

[0011] Furthermore, the locking bar consists of a smooth section and a beveled section, with the beveled section located on the outside of the fixed post.

[0012] Furthermore, the leveling component includes a base, an electric push rod, and a leveling wedge. The lower mold is mounted on the base by a spring. The fixed end of the electric push rod is connected to the base by a fixing block. The telescopic end of the electric push rod is fixedly connected to the leveling wedge. The leveling wedge is slidably mounted on the base, and the inclined end of the leveling wedge abuts against the lower surface of the lower mold.

[0013] Furthermore, the mounting components include a fixed cylinder, a guide cylinder, a locking platform, and a locking groove. The fixed cylinder is fixedly mounted on the base platform and is fixedly connected to the guide cylinder. A locking platform is provided inside the guide cylinder, and a locking groove is provided inside the locking platform. A through groove larger than the diameter of the top block is provided on the locking platform.

[0014] Furthermore, the testing components include a pressure plate, a guide rod, a conductive ring, and an elastic telescopic rod. The pressure plate is connected to the base via the elastic telescopic rod. The pressure plate is fixedly connected to the conductive ring, and the conductive ring is slidably connected to the guide rod. One end of the guide rod is fixedly connected to the locking platform, and the other end of the guide rod is fixedly connected to the base.

[0015] Furthermore, a drive coil is provided on the guide rod, with the current input terminal located at the end of the drive coil closest to the base.

[0016] Furthermore, there are multiple sets of pressure control components, located in the mold splicing seam area. The pressure control components include a pressure control plate and an adjusting spring. The pressure control plate is slidably installed on the upper mold and is connected to the upper mold through the adjusting spring. An electric telescopic rod is installed inside the adjusting spring, and a pressure sensor is installed on the pressure control plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a fixed column moves downward with the upper mold, and a lower top block pushes the pressure plate downward. After being pressed, the pressure plate pushes the elastic telescopic rod to contract, and the conductive ring slides down synchronously along the guide rod, shortening the effective coil length of the circuit, reducing the circuit impedance, and increasing the current. This signal serves as the basis for judging the levelness of the lower mold. If both lower molds are in a standard level state, the downward height of the pressure plates on both sides is consistent when the mold is closed, the current is equal and meets the preset value, and the controller does not level. If one side is biased upward, the downward stroke is short and the current is less than the preset value. The controller instructs the electric push rod of the leveling component on that side to contract, driving the leveling wedge to move outward and reducing the height of the inclined support. The lower mold on that side descends under the action of the spring until the current returns to the standard. If one side is biased downward, the downward stroke is long and the current is greater than the preset value. The controller instructs the electric push rod to extend, and the leveling wedge moves inward to raise that side until the current reaches the standard, completing the automatic correction.

[0018] 2. In this invention, after leveling the upper mold to the mold closing end point, the locking rod is aligned with the locking groove on the side wall of the locking platform. The reset spring pushes the locking rod to extend outward and lock into the locking groove to achieve rigid locking and withstand the mold expansion force. When the mold is opened, the electromagnet is supplied with a current of opposite polarity to overcome the spring force and retract the locking rod to unlock.

[0019] 3. During the forming stage, the adjusting springs of the pressure control components corresponding to each joint maintain the pressure of the pressure control plate. When the measured pressure is lower than the pressure holding threshold, the springs maintain the pressure holding. If the expansion force rises above the threshold, the controller causes the electric telescopic rod inside the adjusting spring to contract and release part of the compression, reducing the pressure and causing the pressure to drop, balancing the force on each area, avoiding overflow, insert deformation and cavity displacement, and ensuring forming accuracy and appearance quality.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Figures 1-9 As shown, the present invention provides the following technical solution: like Figure 1 , Figure 2 As shown, the forming mold includes an upper mold unit 1, a controller is provided on the upper mold unit 1, a pressure control unit 4 is provided on the upper mold unit 1, a lower mold unit 2 is provided on one side of the upper mold unit 1, and a leveling unit 3 is provided on the lower mold unit 2. Upper mold unit 1 includes upper mold 11 and locking member 12; The lower mold unit 2 includes a lower mold 21 and a flattening component 22; Leveling unit 3 includes mounting component 31 and testing component 32; The pressure control unit 4 includes a pressure control component 41; The upper mold 11 is fixedly connected to the pressure control component 41, the locking component 12 is coaxially arranged with the mounting component 31, and the mounting component 31 is fixedly connected to the leveling component 22.

[0024] During the mold closing process of the upper mold 11 and the lower mold 21, the detection component 32 detects whether there is a levelness deviation in the lower mold 21. If there is, the leveling component 22 is used to level it. After leveling, the locking component 12 and the mounting component 31 are used to lock the mold, thereby forming the mold. During the forming process, the pressure control component 41 is used to precisely control the pressure at all times to ensure the forming quality.

[0025] like Figure 6 , Figure 7As shown, the locking component 12 includes a mounting block 121, a fixing post 122, a locking rod 123, a return spring 124, an electromagnet 125, and a top block 126. The mounting block 121 is fixedly mounted on the upper mold 11. The mounting block 121 is fixedly connected to the fixing post 122. The fixing post 122 is slidably connected to the locking rod 123. The locking rod 123 is fixedly connected to the electromagnet 125. There are two electromagnets 125, which are connected by the return spring 124. The top block 126 is fixedly mounted on the end face of the fixing post 122 away from the mounting block 121.

[0026] like Figure 7 As shown, the two electromagnets 125 exhibit opposite polarities when energized.

[0027] like Figure 7 As shown, the locking rod 123 consists of a smooth section and an inclined section, with the inclined section of the locking rod 123 located outside the fixed post 122.

[0028] The staff places the weighed material to be processed into the lower mold 21. After the external heating module heats the material to the set temperature, it melts into a liquid. After melting, the upper mold 11 is moved down to close with the lower mold 21 to pressurize the material. At the same time, the heating module is stopped, allowing the material to solidify under pressure. After solidification, the upper mold 11 is raised to remove the formed product, thus completing the product forming process.

[0029] In the initial stage of mold closing, the upper mold 11 descends smoothly towards the lower mold 21 under the drive of the external press. As the upper mold 11 continues to descend, the fixed column 122 first extends into the guide cylinder 312 on the side of the lower mold 21 to complete the initial centering guidance of mold closing. After continuing to descend, the inclined section of the locking rod 123 contacts the upper edge of the locking platform 313. The end face of the locking platform 313 applies a radially inward component force to the inclined surface, pushing the two locking rods 123 to overcome the elastic force of the return spring 124 and retract towards each other. The two electromagnets 125 also move closer to the locking rods 123 in sync. The return spring 124 is compressed and stores energy. The outer end of the locking rod 123 retracts into the fixed column 122, allowing the fixed column 122 to pass smoothly through the central through slot of the locking platform 313 and continue to descend.

[0030] like Figure 4 , Figure 5 As shown, the leveling component 22 includes a base 221, an electric push rod 222, and a leveling wedge 223. The lower mold 21 is mounted on the base 221 by a spring. The fixed end of the electric push rod 222 is connected to the base 221 by a fixing block. The telescopic end of the electric push rod 222 is fixedly connected to the leveling wedge 223. The leveling wedge 223 is slidably mounted on the base 221. The inclined end of the leveling wedge 223 abuts against the lower surface of the lower mold 21.

[0031] like Figure 6 , Figure 8 , Figure 9 As shown, the mounting component 31 includes a fixed cylinder 311, a guide cylinder 312, a locking platform 313, and a locking groove 314. The fixed cylinder 311 is fixedly mounted on the base 221. The fixed cylinder 311 is fixedly connected to the guide cylinder 312. The locking platform 313 is provided inside the guide cylinder 312. The locking platform 313 has a locking groove 314. The locking platform 313 has a through groove larger than the diameter of the top block 126.

[0032] like Figure 8 , Figure 9 As shown, the detection component 32 includes a pressure plate 321, a guide rod 322, a conductive ring 323, and an elastic telescopic rod 324. The pressure plate 321 is connected to the base 221 through the elastic telescopic rod 324. The pressure plate 321 is fixedly connected to the conductive ring 323. The conductive ring 323 is slidably connected to the guide rod 322. One end of the guide rod 322 is fixedly connected to the locking platform 313, and the other end of the guide rod 322 is fixedly connected to the base 221.

[0033] like Figure 8 , Figure 9 As shown, a drive coil is provided on the guide rod 322, and the end of the drive coil near the base 221 is the current input terminal.

[0034] As the fixed column 122 moves downward, the top block 126 at the bottom gradually contacts and presses the pressure plate 321 of the detection component 32 below, pushing the pressure plate 321 to move downward. After being pressed, the pressure plate 321 pushes the elastic telescopic rod 324 to gradually contract. The conductive ring 323 fixed on the side of the pressure plate 321 slides downward synchronously along the vertically arranged guide rod 322. As the conductive ring 323 slides down with the pressure plate 321, the effective coil length connected to the working circuit continuously shortens, the overall impedance of the circuit decreases accordingly, and the current value continues to rise. This current signal is transmitted to the controller as the core basis for judging the levelness of the lower mold 21.

[0035] When the mold 21 is in a standard horizontal state, after the mold is closed, the downward height of the pressure plates 321 on both sides is completely consistent, the conductive ring 323 stops at the same level, the current values ​​of the circuits on both sides are equal and match the preset standard value, and the controller does not control the leveling.

[0036] If one side of the lower mold 21 is offset upwards, the initial position of the lower mold 21 on that side is higher. When the mold is closed, the downward stroke of the pressure plate 321 pushed by the top block 126 is shorter, the conductive ring 323 stays at a higher position, and the effective coil length connected to the circuit is longer. The corresponding circuit current value will be less than the preset standard value. After receiving the signal, the controller immediately sends a retraction command to the electric push rod 222 of the leveling component 22 on that side. The electric push rod 222 drives the leveling wedge block 223 to slide outwards and exit. The lower mold 21 is suspended above the base 221 by the spring. After the leveling wedge block 223 exits outwards, the support height of its inclined surface on the bottom surface of the lower mold 21 decreases. The lower mold 21 on that side slowly descends under the rebound action of the bottom spring until the circuit current value on that side returns to the preset standard value, and the leveling action stops.

[0037] If one side of the lower mold 21 is offset downwards, the initial position of the lower mold 21 on that side will be lower. When the mold is closed, the downward stroke of the pressure plate 321 will be longer, the position of the conductive ring 323 will be lower, and the effective coil length connected to the circuit will be shorter. The corresponding circuit current value will be greater than the preset standard value. After receiving the signal, the controller sends an extension command to the electric push rod 222 on that side, pushing the leveling wedge 223 to slide inwards. The inclined surface of the leveling wedge 223 gradually wedges into the bottom surface of the lower mold 21, raising the height of the lower mold 21 on that side until the current value on that side is consistent with the preset standard value. The leveling is completed. The mold can automatically correct the horizontal deviation of the lower mold 21 during the mold closing process, reducing the overflow and flash at the splicing seam from the root, and at the same time balancing the mold closing force to ensure the forming quality.

[0038] When leveling is complete and the upper mold 11 descends to the mold closing end point, the position of the locking rod 123 is exactly aligned with the locking groove 314 on the side wall of the locking platform 313. At this time, the radial extrusion force on the locking rod 123 disappears, the return spring 124 releases its elastic force and pushes outward, pushing the two locking rods 123 outward and into the locking groove 314, completing the mechanical locking of the upper mold 11 and the lower mold 21. This locking structure is a rigid locking mechanism that can withstand the mold expansion reaction force during the forming process and prevent the parting surface from opening and causing material to run out. When the mold opens, the controller supplies current to the two electromagnets 125, causing the two electromagnets 125 to present opposite polarities. The opposite magnetic poles attract each other, overcoming the elastic force of the return spring 124 and driving the locking rod 123 to retract inward, disengaging from the locking groove 314. The locking state is released, and the upper mold 11 can then smoothly move upward to open the mold.

[0039] like Figure 3 As shown, there are multiple sets of pressure control components 41, which are located in the mold splice area. The pressure control component 41 includes a pressure control plate 411 and an adjusting spring 412. The pressure control plate 411 is slidably installed on the upper mold 11. The pressure control plate 411 is connected to the upper mold 11 through the adjusting spring 412. An electric telescopic rod is provided inside the adjusting spring 412. A pressure sensor is provided on the pressure control plate 411.

[0040] During the forming stage, the pressure control components 41, located in the corresponding areas of each splice seam, independently perform pressure regulation to solve the problems of uneven expansion force at the splice seams of the split mold and the inability of the rigid upper mold 11 to provide zoned pressure compensation. When the expansion force in the splice seam area is small and the measured pressure is lower than the set pressure holding threshold, the adjusting spring 412 maintains the clamping force of the pressure control plate 411 by its own compression elasticity, providing stable pressure holding in that area and ensuring the parting surface fits and seals. When the expansion force in the splice seam area increases and the measured pressure exceeds the set threshold, the controller controls the electric telescopic rod inside the adjusting spring 412 to retract, releasing part of the spring's compression and reducing the output clamping force of the adjusting spring 412 on the pressure control plate 411, causing the pressure in that area to fall back to the set range. This avoids overflow and flash caused by insufficient local pressure, and also prevents insert deformation and cavity displacement caused by excessive local pressure, effectively ensuring the forming accuracy and texture appearance quality of the product.

[0041] Working principle of the invention: The staff places the weighed material to be processed into the lower mold 21. After the external heating module heats the material to the set temperature, it melts into a liquid. After melting, the upper mold 11 is moved down to close with the lower mold 21 to pressurize the material. At the same time, the heating module is stopped, allowing the material to solidify under pressure. After solidification, the upper mold 11 is raised to remove the formed product, thus completing the product forming process.

[0042] During the mold closing stage, the fixed column 122 moves downward with the upper mold 11, and the lower top block 126 pushes the pressure plate 321 downward. After being pressed, the pressure plate 321 pushes the elastic telescopic rod 324 to contract, and the conductive ring 323 slides down synchronously along the guide rod 322, shortening the effective coil length of the circuit, reducing the circuit impedance, and increasing the current. This signal serves as the basis for judging the levelness of the lower mold 21. If both lower molds 21 are in a standard level state, the downward height of the pressure plates 321 on both sides will be consistent when the mold is closed, and the current will be equal. If the preset value is met, the controller will not level the surface. If one side is tilted upwards, the downward stroke will be short and the current will be less than the preset value. The controller will instruct the electric push rod 222 of the leveling component 22 on that side to retract, causing the leveling wedge block 223 to move outwards and reduce the height of the inclined support. The lower mold 21 on that side will descend under the action of the spring until the current returns to the standard. If one side is tilted downwards, the downward stroke will be long and the current will be greater than the preset value. The controller will instruct the electric push rod 222 to extend, and the leveling wedge block 223 to move inwards and lift that side until the current reaches the standard, thus completing the automatic correction.

[0043] During the forming stage, the adjusting springs 412 of the pressure control components 41 corresponding to each joint maintain the clamping force of the pressure control plate 411. When the measured pressure is lower than the pressure holding threshold, the springs maintain the pressure holding. If the mold expansion force increases beyond the threshold, the controller causes the electric telescopic rod inside the adjusting spring 412 to retract and release part of the compression, reducing the clamping force and causing the pressure to drop, balancing the force on each area, avoiding overflow, insert deformation and cavity displacement, and ensuring forming accuracy and appearance quality.

[0044] After leveling, the upper mold 11 reaches the mold closing end point, the locking rod 123 is aligned with the locking groove 314 on the side wall of the locking platform 313, and the reset spring 124 pushes the locking rod 123 to extend outward and lock into the locking groove 314 to achieve rigid locking and withstand the product expansion force. When the mold is opened, the electromagnet 125 is supplied with a current of opposite polarity to overcome the spring force and retract the locking rod 123 to unlock.
