Description

Technical Field

[0001] This invention belongs to the field of die-casting equipment technology, specifically an automated die-casting molding device for separation plates. Background Technology

[0002] Separator plates are functional metal sheets, typically with specific holes. Separator plate manufacturing usually employs automated die-casting molding equipment, a specialized and highly efficient production line that combines die-casting technology with automation.

[0003] In existing automated die-casting molding equipment for separation plates, a release agent spraying process is typically required inside the molding cavity during operation. This ensures sufficient adhesion of the release agent to the inner surfaces of the molding cavity, including the cavity and core, guaranteeing stable demolding after die casting. However, in practice, before complete mold closure, the sprayed area is largely exposed to the external environment. Besides adhering to the cavity, a significant amount of the atomized release agent remains suspended and dispersed in the air, causing air pollution and resulting in substantial waste of the release agent.

[0004] In addition, because the separation plate has slots, the core is fitted on the outside of the slots during molding, making separation difficult after curing and easily causing deformation of the inner wall of the slots, resulting in poor overall die casting molding effect. Summary of the Invention

[0005] The purpose of this invention is to provide an automated die-casting apparatus for separating plates, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated die-casting molding device for a separation plate, comprising a fixed mold, a moving mold, an injection tube, a gate, a cavity, and an adapter groove. The cavity and adapter groove are both located on the front side of the moving mold. A core component is rotatably mounted on the front side of the fixed mold. A cooling chamber I is located inside the fixed mold. A rotation control unit is located on the side of the fixed mold, controlling the reciprocating rotation of the core component. An adapter connecting part is located inside the moving mold, corresponding one-to-one with the core component. A second cooling chamber is located inside the moving mold, and an ejector pin assembly and an elastic feedback assembly are respectively mounted inside the second cooling chamber. The movable end of the elastic feedback assembly is movably sleeved within the adapter connecting part.

[0007] The core component is provided with water passage holes and an automatic spraying component. The automatic spraying component resists the elastic feedback component during the closing of the moving mold and the fixed mold, and automatically sprays and fills the cavity with release agent.

[0008] Preferably, the automatic spraying assembly includes a storage cavity, an electric push rod, a piston plate, a pressure sensing part, an elastic filling block, and a slit. The electric push rod and the piston plate are both disposed in the storage cavity. The piston plate is fixedly connected to the movable end of the electric push rod. The pressure sensing part is fixed inside the storage cavity, and the pressure sensing plate of the pressure sensing part is located at the end of the core and senses contact pressure. The elastic filling block is fixedly nested on the outer side of the core. The slit is opened on the elastic filling block, and the slit communicates with the storage cavity when it expands elastically. The storage cavity is filled with a release agent.

[0009] Preferably, the cooling chamber includes an assembly cavity, a main cooling cavity, and an intermediate cavity. The assembly cavity, the main cooling cavity, and the intermediate cavity are all located inside the fixed mold. The two ends of the intermediate cavity are respectively connected to the assembly cavity and the main cooling cavity. The back of the fixed mold is provided with a guide portion, which guides cooling water into the assembly cavity.

[0010] Preferably, the rotation control unit includes a gear, a toothed plate, a second electric push rod, a connecting rod, and a movable plate. The gear is fixedly sleeved on the outer surface of the core part. The toothed plate meshes with the gear and is fixedly connected to the movable plate. The side of the fixed mold is provided with a sleeve interface. The movable plate is movably sleeved in the sleeve interface. One end of the connecting rod is movably sleeved in the sleeve interface and fixedly connected to the movable plate. The second electric push rod is fixed on the outside of the fixed mold and controls the movement of the connecting rod.

[0011] Preferably, the adaptable connecting part includes a sleeve hole, a first hole, and a second hole. The sleeve hole communicates with the cavity. The first hole and the second hole are both opened inside the moving mold and communicate with the sleeve hole. The first hole and the second hole are both communicated with the cooling chamber. The sleeve hole is adapted to the core part, and after the mold is closed, one end of the core part is movably sleeved and nested in the sleeve hole. The first hole is adapted to the elastic feedback component, and the second hole is located on the rotation path of the water passage hole.

[0012] Preferably, the elastic feedback assembly includes a movable rod, a first spring, a positioning rod, and a pressure sensing block. One end of the first spring is fixed in the second cooling chamber, and the other end of the first spring is fixedly connected to the movable rod. One end of the movable rod is movably sleeved in a first hole. The positioning rod is fixed in the second cooling chamber, and the pressure sensing block is fixed at the end of the positioning rod. The positioning rod and the movable rod are aligned on the same axis, and the first spring is located outside the positioning rod.

[0013] Preferably, the moving mold has an outlet on its side, which is connected to the cooling chamber. The adapter groove is located on the outside of the cavity and adapts to the front structure of the fixed mold.

[0014] Preferably, an elastic column is fixedly sleeved inside the core component, and an auxiliary slit is opened inside the elastic column. The auxiliary slit opens under pressure, and the two ends of the opened auxiliary slit are respectively connected to the storage cavity and the cooling cavity.

[0015] Preferably, the elastic feedback component controls the ejector assembly to automatically eject the molding separation plate when die casting is completed and the mold is separated. The ejector assembly includes a connecting plate, an ejector pin, and an electric push rod three. The ejector pin is movably sleeved in the moving mold, and the outer end of the ejector pin is parallel to the inner wall of the cavity. The ejector pin is fixed on the connecting plate. The electric push rod three is fixed in the cooling chamber two, and the movable end of the electric push rod three is fixedly connected to the connecting plate. When the pressure sensing block senses the pressure disappearing, the electric push rod three, in conjunction with the external control mechanism, controls the electric push rod opening to delay its action.

[0016] Preferably, the injection tube is disposed on the back of the fixed mold and communicates with the gate opened inside the fixed mold. The interior of the moving mold is provided with a flow channel, the two ends of which are communicated with two symmetrically distributed cavities, and the flow channel is connected to the gate when the mold is closed.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) This invention utilizes a rotation control unit, an elastic feedback component, and an automatic spraying component in the core component. During mold closing, the elastic feedback component's contact with the core component allows the automatic spraying component in the core component to sense and automatically spray the release agent. This achieves automatic spraying and filling upon mold closing, which avoids the release agent being dispersed into the air due to spraying before mold closing. Furthermore, by combining the core component with the matching connecting part, the release agent spraying port is automatically sealed after complete mold closing, thus ensuring stable subsequent die casting and achieving good performance.

[0019] (2) By further utilizing the rotation control unit to control the rotation of the core part, the present invention achieves the switching of the nozzle orientation of the automatic spraying component by controlling the deflection of the core part during the actual mold closing and filling of the release agent. During the internal filling spraying during the mold closing, the dynamic angle spraying method is adopted, which further improves the spraying adhesion effect of the release agent in the cavity and on the outer side of the core part. While improving the overall spraying and filling efficiency, it further improves the adhesion effect, ensures the stability of subsequent demolding, and avoids local adhesion.

[0020] (3) By using the rotation control unit to drive the rotation of the core part, the present invention maintains a slight deflection during the cooling and molding process, and ensures that the core part is effectively separated from the molding slot on the separation plate after molding. By using the dynamic state, the core part is prevented from being fixedly stuck in the slot of the molding separation plate, which greatly improves the subsequent demolding effect, avoids the deformation of the slot of the separation plate caused by adhesion, and has a good molding effect.

[0021] (4) This invention further utilizes the elastic feedback component, which works in conjunction with the external control terminal. During mold closing, the elastic feedback component is compressed to achieve synchronous sensing of the pressure sensing block. During mold opening, the elastic feedback component is used to restore the elasticity of the pressure sensing block, so that the pressure sensing block senses the disappearance of the resistance pressure. Combined with the signal of the disappearance of pressure, the ejector pin assembly is controlled to move synchronously during mold opening and to complete the ejection process of the separation plate. The demolding process is completed quickly at the same time as the mold opening is completed. It is highly automated, demolds quickly, and accelerates the efficiency of continuous production.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0033] like Figures 1 to 9 As shown, this embodiment of the invention provides an automated die-casting molding device for a separation plate, including a fixed mold 1, a moving mold 2, an injection tube 3, a gate 4, a cavity 5, and an adapter groove 13. The cavity 5 and the adapter groove 13 are both located on the front side of the moving mold 2. A core 8 is rotatably provided on the front side of the fixed mold 1. A cooling chamber 9 is provided inside the fixed mold 1. A rotation control unit 10 is provided on the side of the fixed mold 1, which controls the reciprocating rotation of the core 8. An adapter connecting part 7 is provided inside the moving mold 2, and the adapter connecting part 7 corresponds one-to-one with the core 8. A second cooling chamber 11 is provided inside the moving mold 2. An ejector pin assembly 16 and an elastic feedback assembly 12 are respectively provided inside the second cooling chamber 11. The movable end of the elastic feedback assembly 12 is movably sleeved in the adapter connecting part 7. A water passage hole 17 and an automatic spraying assembly are respectively provided inside the core 8. The automatic spraying assembly abuts against the elastic feedback assembly 12 during the mold closing of the moving mold 2 and the fixed mold 1, and automatically sprays and fills the cavity 5 with a release agent.

[0034] Example 1: In use, as the moving mold 2 moves and closes with the fixed mold 1, the moving mold 2 and the fixed mold 1 gradually approach each other, and the fitting groove 13 gradually engages with the front fitting of the fixed mold 1. The core 8 in the fixed mold 1 approaches the cavity 5 in the moving mold 2 and abuts against the moving elastic feedback component 12. The elastic feedback component 12 is elastically compressed by the spring 122 and gradually retracts into the cooling chamber 11 along the first hole 72. The pressure sensing part 21 of the contact area at the end of the core 8 senses the contact pressure, and causes the external remote control unit to receive the signal and control the electric push rod 19 to move, driving the piston plate 20 to move in the storage cavity 18, squeezing the internal release agent, causing the hydraulic pressure in the compression area of ​​the storage cavity 18 to rise, and acting on the elastic filling block 22, causing the slit 23 in the elastic filling block 22 to open under hydraulic pressure, and causing the squeezed release agent to be quickly sprayed and filled into the cavity 5 after mold closing and the outer core 8. Simultaneously, the core 8 is inserted into the sleeve hole 71, and after the mold is closed, the external liquid supply end sprays molten metal into the injection tube 3, and fills the cavity 5 along the gate 4 and runner 6. After injection, the mold closing pressure is maintained, and die casting is performed. Then, external cooling water is introduced into the cooling chamber 9 of the fixed mold 1 through the guide part 14. As it cools, it enters the cooling chamber 9 and fills the main cooling chamber 92. Part of the coolant is introduced into the internal water passage hole 17 of the core 8 through the assembly cavity 91. As the core 8 rotates, the cooling water in the water passage hole 17 is intermittently introduced into the cooling chamber 11 of the moving mold 2 through the second hole 73, and is discharged through the outlet 15. After molding and cooling are completed, the cooling water input is stopped, and the moving mold 2 is moved and reset. The core 8 is separated from the molding separation plate, and the ejector pin assembly 16 is activated to push out the molding separation plate in the cavity 5, completing the discharge after automatic die casting.

[0035] First, by utilizing the rotation control unit 10, the elastic feedback component 12, and the automatic spraying component in the core part 8, during mold closing, the elastic feedback component 12's contact with the core part 8 causes the automatic spraying component in the core part 8 to sense and automatically spray the release agent. This achieves automatic spraying and filling upon mold closing, preventing the release agent from dispersing into the air due to spraying before mold closing. Furthermore, by combining the core part 8 with the matching connecting part 7, the release agent spraying port is automatically sealed after complete mold closing, thus ensuring stable subsequent die casting and good performance.

[0036] Furthermore, by further utilizing the rotation control unit 10 to control the rotation of the core part 8, during the actual mold closing and filling of the release agent, the orientation of the nozzle of the automatic spraying component is switched by controlling the deflection of the core part 8. During the internal filling spraying during mold closing, a dynamic angle spraying method is adopted, which further improves the spraying adhesion effect of the release agent in the cavity 5 and on the outer side of the core part 8. While improving the overall spraying and filling efficiency, it further improves the adhesion effect, ensures the stability of subsequent demolding, and avoids local adhesion.

[0037] On the other hand, by using the rotation control unit 10 to drive the rotation of the core part 8, during the cooling and molding process, by maintaining a slight deflection, the core part 8 is effectively separated from the molding slot on the separation plate after molding. By utilizing the dynamic state, the core part 8 is prevented from being fixedly stuck in the slot of the molding separation plate, which greatly improves the subsequent demolding effect, avoids the deformation of the slot of the separation plate caused by adhesion, and results in a good molding effect.

[0038] Example 2: When the fixed mold 1 and the moving mold 2 are closed, as the elastic feedback component 12 abuts against the core part 8, the movable rod 121 in the elastic feedback component 12 is compressed and moved, compressing the spring 122. At the same time, the movable rod 121 abuts against the pressure sensing block 124 on the positioning rod 123. The pressure sensing block 124 senses the pressure. When the mold is separated, as the elastic feedback component 12 gradually elastically resets, the pressure sensing block 124 changes from sensing pressure to sensing no pressure. At this time, the external control terminal receives the signal and can control the ejector pin assembly 16 to delay its action. As the moving mold 2 and the fixed mold 1 gradually separate, the ejector pin assembly 16 moves once and resets. As the moving mold 2 and the fixed mold 1 are completely separated, the ejector pin assembly 16 synchronously completes the separation of the molding separation plate, completing the automatic synchronous unloading.

[0039] First, by further utilizing the elastic feedback component 12, and cooperating with the external control terminal, during mold closing, the elastic feedback component 12 is compressed to achieve synchronous sensing of the pressure sensing block 124. During mold separation, in conjunction with the elastic recovery of the elastic feedback component 12, the pressure sensing block 124 senses the disappearance of the resisting pressure. Based on the signal of the disappearance of pressure, the ejector pin assembly 16 is controlled to move synchronously during mold separation and complete the ejection process of the separation plate. The demolding process is completed quickly at the same time as the mold separation is completed, which is highly automated, fast demolding, and accelerates the efficiency of continuous production.

[0040] The automatic spraying assembly includes a storage cavity 18, an electric push rod 19, a piston plate 20, a pressure sensing part 21, an elastic filling block 22, and a slit 23. The electric push rod 19 and the piston plate 20 are both disposed in the storage cavity 18. The piston plate 20 is fixedly connected to the movable end of the electric push rod 19. The pressure sensing part 21 is fixed inside the storage cavity 18, and the pressure sensing plate of the pressure sensing part 21 is located at the end of the core part 8 and senses the contact pressure. The elastic filling block 22 is fixedly nested on the outer side of the core part 8. The slit 23 is opened on the elastic filling block 22, and the slit 23 communicates with the storage cavity 18 when it expands elastically. The storage cavity 18 is filled with a release agent.

[0041] By using the pressure sensing unit 21 in the automatic spraying assembly to sense the contact pressure and start the spraying, the closed release agent spraying during mold closing is completed to prevent leakage. The slit 23 closes without pressure to prevent leakage and is sprayed out under pressure.

[0042] The side of the core part 8 is provided with a removable sealing plug. When the sealing plug is opened, the release agent can be injected from the outside of the core part 8 along the front of the fixed mold 1.

[0043] The cooling chamber 9 includes an assembly cavity 91, a main cooling cavity 92, and an intermediate cavity 93. The assembly cavity 91, the main cooling cavity 92, and the intermediate cavity 93 are all located inside the fixed mold 1. The two ends of the intermediate cavity 93 are connected to the assembly cavity 91 and the main cooling cavity 92, respectively. A guide section 14 is provided on the back of the fixed mold 1, which guides cooling water into the assembly cavity 91.

[0044] While the cooling chamber 9 provides cooling water, the main cooling chamber 92 fits the position and structure of the cavity 5 to improve the cooling effect, and the assembly cavity 91 provides assembly space for the rotation control unit 10.

[0045] The rotation control unit 10 includes a gear 101, a toothed plate 102, an electric push rod 103, a connecting rod 104, and a movable plate 105. The gear 101 is fixedly sleeved on the outer surface of the core part 8. The toothed plate 102 meshes with the gear 101 and is fixedly connected to the movable plate 105. The side of the fixed mold 1 is provided with a sleeve interface. The movable plate 105 is movably sleeved in the sleeve interface. One end of the connecting rod 104 is movably sleeved in the sleeve interface and fixedly connected to the movable plate 105. The electric push rod 103 is fixed on the outside of the fixed mold 1 and controls the movement of the connecting rod 104.

[0046] The rotation control unit 10 realizes the reciprocating deflection of the gear 101 by the lateral reciprocating movement of the toothed plate 102, thereby realizing the reciprocating deflection action (i.e., reciprocating rotation) of the core part 8.

[0047] The adapter connecting part 7 includes a sleeve hole 71, a first hole 72, and a second hole 73. The sleeve hole 71 is connected to the cavity 5. The first hole 72 and the second hole 73 are both opened inside the moving mold 2 and are connected to the sleeve hole 71. The first hole 72 and the second hole 73 are both connected to the cooling chamber 11. The sleeve hole 71 is adapted to the core part 8, and after the mold is closed, one end of the core part 8 is movably sleeved and nested in the sleeve hole 71. The first hole 72 is adapted to the elastic feedback component 12, and the second hole 73 is located on the rotation path of the water passage hole 17.

[0048] The adapter connecting part 7 is adapted to the positioning sleeve of the core part 8 and can seal the spray port of the automatic spraying component. The first hole 72 is adapted to the sleeve of the movable rod 121 in the elastic feedback component 12. The second hole 73 cooperates with the eccentrically set water passage hole 17 to conduct intermittent cooling water under rotation. On the one hand, it increases the residence time of cooling water in the cooling chamber 9 and improves the cooling water utilization rate. On the other hand, by using the water passage hole 17 in the core part 8 for conduction, the core part 8 reduces the distance between the cooling water and the molding separation plate, and further enhances the cooling effect from the middle area.

[0049] The elastic feedback component 12 includes a movable rod 121, a spring 122, a positioning rod 123, and a pressure sensing block 124. One end of the spring 122 is fixed in the second cooling chamber 11, and the other end of the spring 122 is fixedly connected to the movable rod 121. One end of the movable rod 121 is movably sleeved in the first hole 72. The positioning rod 123 is fixed in the second cooling chamber 11, and the pressure sensing block 124 is fixed at the end of the positioning rod 123. The positioning rod 123 and the movable rod 121 are aligned on the axis, and the spring 122 is located outside the positioning rod 123.

[0050] The elastic feedback component 12 compresses to adapt to the squeezing and contact with the core component 8, thereby sensing the automatic spraying component. At the same time, in conjunction with the pressure sensing of the internal pressure sensing block 124, it realizes demolding processing under the induction start during mold parting.

[0051] The moving mold 2 has an outlet 15 on its side, which is connected to the cooling chamber 11. The adapter groove 13 is located on the outside of the cavity 5 and adapts to the front structure of the fixed mold 1.

[0052] The outlet 15 discharges the cooling water in the moving mold 2. The adapter groove 13 adapts to the mold closing process, ensuring that the core part 8 is fully positioned and sleeved before the adapter connecting part 7 is relatively closed to the cavity 5, reducing the leakage opening area, ensuring the internal filling of the subsequent mold release agent, and avoiding leakage. At this time, the internal relative air can be bypassed through the adapter connecting part 7, avoiding the difficulty of closing due to complete sealing. A small amount of mold release agent is bypassed to the cooling cavity 11 through the adapter connecting part 7, with minimal loss and avoiding direct dispersion in the air.

[0053] The core component 8 is also fitted with an elastic column 24, which has an auxiliary slit inside. The auxiliary slit opens under pressure, and the two ends of the opened auxiliary slit are connected to the storage cavity 18 and the cooling cavity 9, respectively.

[0054] Through the elastic column 24 and the auxiliary slit in the elastic column 24, the partial opening of the storage cavity 18 in the core part 8 is maintained. When the piston plate 20 moves along the storage cavity 18, the change in air pressure in the right cavity is avoided, which would inhibit the movement of the piston plate 20. That is, the right side of the piston plate 20 is connected to the cooling chamber 9 through the auxiliary slit, maintaining stable air pressure and avoiding the difficulty of piston plate 20 movement caused by partial sealing. Moreover, the auxiliary slit can be kept relatively closed to prevent a large amount of cooling water from entering the right cavity of the storage cavity 18.

[0055] Among them, the elastic feedback component 12 controls the ejector assembly 16 to automatically eject the molding separation plate when the die casting is completed and the mold is separated. The ejector assembly 16 includes a connecting plate 161, an ejector pin 162 and an electric push rod 163. The ejector pin 162 is movably sleeved in the moving mold 2, and the outer end of the ejector pin 162 is parallel to the inner wall of the cavity 5. The ejector pin 162 is fixed on the connecting plate 161. The electric push rod 163 is fixed in the cooling chamber 11, and the movable end of the electric push rod 163 is fixedly connected to the connecting plate 161. When the pressure sensing block 124 senses the pressure disappearing, the electric push rod 163 is controlled by the external control mechanism to delay its action.

[0056] The elastic feedback component 12 controls the start of the ejector pin assembly 16 through the pressure sensing block 124 and the external control terminal, and realizes synchronous automatic demolding by utilizing the timely start of the ejector pin assembly 16, thereby improving continuous production efficiency.

[0057] The injection tube 3 is located on the back of the fixed mold 1 and is connected to the gate 4 inside the fixed mold 1. The moving mold 2 is provided with a runner 6. The two ends of the runner 6 are connected to two symmetrically distributed cavities 5, and the runner is connected to the gate 4 when the mold is closed.

[0058] The working principle and usage process of this invention are as follows: During use, as the moving mold 2 moves and closes with the fixed mold 1, the moving mold 2 and the fixed mold 1 gradually approach each other, and the fitting groove 13 gradually engages with the front fitting of the fixed mold 1. The core 8 in the fixed mold 1 approaches the cavity 5 in the moving mold 2 and abuts against the moving elastic feedback component 12. The elastic feedback component 12 is elastically compressed by the spring 122 and gradually retracts into the cooling chamber 11 along the first hole 72. The pressure sensing part 21 at the end of the core 8 abuts senses the abutting pressure, causing the external remote control unit to receive the signal and control the electric push rod 19 to move, driving the piston plate 20 in the storage cavity 18. The movement and compression of the internal release agent cause the hydraulic pressure in the compression area of ​​the storage cavity 18 to rise and act on the elastic filler block 22. This causes the slits 23 in the elastic filler block 22 to open under hydraulic pressure, and the extruded release agent is rapidly sprayed and filled into the cavity 5 after mold closing and the outside of the core 8. At the same time, the core 8 is inserted into the sleeve hole 71. After mold closing, the external liquid supply end sprays molten metal into the injection tube 3 and fills the cavity 5 along the gate 4 and runner 6. After injection, the mold closing pressure is maintained, and die casting is performed. Subsequently, external cooling water is introduced into the cooling chamber 9 of the fixed mold 1 through the guide part 14. As cooling occurs, the water enters the cooling chamber 9. In step 9, the coolant is filled into the main cooling cavity 92, and part of the coolant is introduced into the internal water passage 17 of the core 8 through the assembly cavity 91. As the core 8 rotates, the cooling water in the water passage 17 is intermittently introduced into the cooling chamber 11 of the moving mold 2 through the second hole 73, and discharged through the outlet 15. After molding and cooling are completed, the cooling water input is stopped, and the moving mold 2 is moved and reset. The core 8 is separated from the molding separation plate, and the ejector assembly 16 is activated to push out the molding separation plate in the cavity 5, completing the material discharge after automatic die casting. When the fixed mold 1 and the moving mold 2 are closed, as the elastic feedback assembly 12 abuts against the core 8, the elastic feedback... The movable rod 121 in the feed assembly 12 is compressed and moved, compressing the spring 122. At the same time, the movable rod 121 abuts against the pressure sensing block 124 on the positioning rod 123. The pressure sensing block 124 senses the pressure. When the mold is separated, as the elastic feedback assembly 12 gradually elastically resets, the pressure sensing block 124 changes from sensing pressure to sensing no pressure. At this time, the external control terminal receives the signal and can control the ejector assembly 16 to delay its action. As the moving mold 2 and the fixed mold 1 gradually separate, the ejector assembly 16 moves once and resets. As the moving mold 2 and the fixed mold 1 completely separate, the ejector assembly 16 synchronously completes the separation of the molding separation plate, completing the automatic synchronous unloading.
