Description

Technical Field

[0001] This utility model relates to the field of socket panel processing technology, specifically a socket panel plastic mold with a core-pulling demolding mechanism. Background Technology

[0002] Plastic molds are required for the processing of socket panels. A plastic mold is a general term for a combination mold used in compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold's punch and die and auxiliary molding system can produce a series of plastic parts of different shapes and sizes. Core pulling demolding is a key structural design in injection molds for handling the demolding of complex-shaped parts. Its core purpose is to achieve smooth demolding of parts within complex cavities through a specific mechanism.

[0003] Existing plastic molds with core-pulling demolding mechanisms typically use mechanical ejection during the ejection process. This process can cause damage to the molded part due to the rigid separation of the molded part from the mold cavity, affecting the quality of the molded part. Utility Model Content

[0004] The purpose of this invention is to provide a socket panel plastic mold with a core-pulling and demolding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a socket panel plastic mold with a core-pulling and demolding mechanism, comprising a base plate, an ejector box, and a lower mold. The ejector box is fixed to the upper side of the base plate, and the lower mold is installed on the upper side of the ejector box. A rotating conical tooth is rotatably arranged inside the lower side of the ejector box, and a lead screw is fixed to the upper side of the rotating conical tooth. A movable sleeve is sleeved on the outer side of the lead screw, and a connecting plate is fixed to the upper side of the movable sleeve. An ejector block is installed above the connecting plate, and a small ejector block is elastically connected inside the ejector block by a spring. A micro air jet hole is opened on the lower outer wall of the small ejector block, and a connecting pipe is connected below the micro air jet hole. A micro air pump is installed at the end of the connecting pipe. An upper mold is installed on the upper side of the lower mold.

[0006] Furthermore, a drive assembly is installed on one side of the ejector box, and the drive assembly includes a micro motor, a rotating shaft and an active bevel gear. The micro motor has a rotating shaft on one side, and an active bevel gear is fixed at one end of the rotating shaft.

[0007] Furthermore, the active bevel gear is meshed with the rotating bevel gear, and a transmission bevel gear is meshed between adjacent rotating bevel gears, and the transmission bevel gear is rotatably connected to the bottom surface of the ejector box.

[0008] Furthermore, the top of the connecting plate is fixedly connected to the small top block, and the connecting plate slides through the lower wall of the top block.

[0009] Furthermore, the small top block penetrates the upper wall of the ejector block and is slidably connected to it; both the small top block and the ejector block are circular structures.

[0010] Furthermore, a lifting plate is integrally fixed to the lower outer ring of the small top block, and blocking blocks are fixed to the lower walls on both sides of the inner side of the top block.

[0011] Furthermore, a limiting frame is fixed on one side of the movable sleeve, and a limiting rod is fixed at the bottom of the lower mold corresponding to the position of the limiting frame. At the same time, the limiting frame is located outside the limiting rod and is slidably connected to the limiting rod up and down.

[0012] Furthermore, the ejector block penetrates the lower wall of the lower mold and is slidably connected to it, and a sealing ring is provided between the ejector block and the through hole of the lower mold.

[0013] This utility model provides a socket panel plastic mold with a core-pulling and demolding mechanism, which has the following features:

[0014] Beneficial effects:

[0015] This utility model is equipped with a heat dissipation component. A micro motor and a rotating shaft facilitate the rotation of the active bevel gear. The active bevel gear and the rotating bevel gear are meshed together to facilitate the rotation of the rotating bevel gear and the lead screw. Transmission bevel gears are meshed between adjacent rotating bevel gears, so that several transmission bevel gears can drive several rotating bevel gears to rotate synchronously. This allows for the synchronous use of multiple small ejector blocks and ejection blocks, resulting in more uniform ejection. The small ejector blocks protrude from the ejection blocks to pre-eject the socket panel forming parts inside the lower mold. Then, the lifting plate on the lower side of the ejection block continues to move upward, which can drive the entire lifting plate to move upward, thereby achieving a comprehensive and sufficient ejection.

[0016] This utility model is equipped with a protective component. During the rotation of the lead screw, the limiting frame on one side of the moving sleeve slides up and down on the outside of the limiting rod, so that the rotation of the lead screw can drive the moving sleeve to move up and down, thereby driving the connecting plate and the small top block to move upward. This causes the small top block to protrude from the ejector block and expose the micro air jet hole. Then, air can be injected into the small top block through a micro air pump and several interconnected connecting pipes. The gas is ejected through the micro air jet hole, so as to facilitate the separation between the mold and the socket panel molding part inside by using gas pressure, reducing the possibility of damage caused by hard separation of the molding part.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-2 As shown, a socket panel plastic mold with a core-pulling and demolding mechanism includes a base plate 1, an ejector box 2, and a lower mold 3. The ejector box 2 is fixed to the upper side of the base plate 1, and the lower mold 3 is installed on the upper side of the ejector box 2. A rotating conical tooth 4 is rotatably arranged on the lower side of the interior of the ejector box 2, and a lead screw 5 is fixed to the upper side of the rotating conical tooth 4. A drive assembly 7 is installed on one side of the ejector box 2, and the drive assembly 7 includes a micro motor 701, a rotating shaft 702, and a drive bevel gear 703. The rotating shaft 702 is arranged on one side of the micro motor 701, and the drive bevel gear 703 is fixed to one end of the rotating shaft 702. The drive bevel gear 703 is connected to the rotating shaft 701. The conical teeth 4 are meshed, and a transmission conical tooth 6 is meshed between adjacent rotating conical teeth 4. The transmission conical tooth 6 is rotatably connected to the bottom surface of the ejector box 2. The micro motor 701 and the rotating shaft 702 facilitate the rotation of the active bevel gear 703. The active bevel gear 703 is meshed with the rotating conical teeth 4, which facilitates the rotation of the rotating conical teeth 4 and the lead screw 5. The transmission conical teeth 6 are meshed between adjacent rotating conical teeth 4, so that several transmission conical teeth 6 can drive several rotating conical teeth 4 to rotate synchronously, thereby enabling the synchronous use of multiple small ejector blocks 12 and ejector blocks 10, resulting in more uniform ejection.

[0023] like Figures 1-3As shown, a movable sleeve 8 is fitted around the outer side of the lead screw 5, and a connecting plate 9 is fixed to the upper side of the movable sleeve 8. An ejector block 10 is installed above the connecting plate 9, and a small ejector block 12 is elastically connected inside the ejector block 10 via a spring 11. A micro air jet hole 13 is opened on the lower outer wall of the small ejector block 12, and a connecting pipe 19 is connected below the micro air jet hole 13. A micro air pump 20 is installed at the end of the connecting pipe 19. An upper mold 21 is installed on the upper side of the lower mold 3. During the rotation of the lead screw 5, the limiting frame 16 on one side of the movable sleeve 8 is positioned relative to the limiting rod. The outer side of 17 slides up and down, so that the rotation of the lead screw 5 can drive the moving sleeve 8 to move up and down, thereby driving the connecting plate 9 and the small top block 12 to move up, so that the small top block 12 protrudes from the ejector block 10 and the micro air jet hole 13 is exposed. Then, air can be injected into the small top block 12 through the micro air pump 20 and several interconnected connecting pipes 19. The gas is ejected through the micro air jet hole 13, so as to facilitate the separation between the mold 3 and the socket panel molding part inside it with the assistance of gas pressure, reducing the possibility of damage caused by hard separation of the molding part.

[0024] like Figures 1-2 As shown, the top of the connecting plate 9 is fixedly connected to the small top block 12, and the connecting plate 9 slides through the lower wall of the ejector block 10. The small top block 12 passes through the upper wall of the ejector block 10 and is slidably connected to it. Both the small top block 12 and the ejector block 10 are circular structures. A lifting plate 14 is integrally fixed to the lower outer ring of the small top block 12. At the same time, blocking blocks 15 are fixed to the lower walls on both sides of the ejector block 10. A limit frame 16 is fixed to one side of the moving sleeve 8. A limit rod 17 is fixed to the bottom of the lower mold 3 at the position corresponding to the limit frame 16. The limit frame 16 is located outside the limit rod 17 and is slidably connected to the limit rod 17. The ejector block 10 passes through the lower wall of the lower mold 3 and is slidably connected to it. The sliding connection is provided, and a sealing ring 18 is provided between the ejector block 10 and the through hole of the lower mold 3; the small ejector block 12 protrudes from the ejector block 10 so that the small ejector block 12 pre-ejects the socket panel molding part inside the lower mold 3, and then the lifting plate 14 on the lower side of the ejector block 10 continues to move upward, which can drive the entire lifting plate 14 to move upward, thereby performing a full and sufficient ejection. Conversely, when the moving sleeve 8 moves downward, the connecting plate 9 first drives the small ejector block 12 to retract. When the lifting plate 14 moves downward to the position of the blocking block 15, it can drive the blocking block 15 and the ejector block 10 to move downward, so that the ejector block 10 retracts into the through hole of the lower wall of the lower mold 3, so as to facilitate the injection molding of the next socket panel.

[0025] In summary, as Figures 1-3As shown, the socket panel plastic mold with core-pulling and demolding mechanism, after the injection-molded socket panel is formed, can first drive the rotation of the active bevel gear 703 through the micro motor 701 and the rotating shaft 702. The active bevel gear 703 is meshed with the rotating bevel gear 4, which can drive the rotation of the rotating bevel gear 4 and the lead screw 5. The adjacent rotating bevel gears 4 are meshed with the transmission bevel gears 6, so that several transmission bevel gears 6 can drive several rotating bevel gears 4 to rotate synchronously, thereby enabling the synchronous use of multiple small ejector blocks 12 and ejector blocks 10, and making the ejection more uniform. During the rotation of the lead screw 5, the limiting frame 16 on one side of the moving sleeve 8 slides up and down on the outside of the limiting rod 17, so that the rotation of the lead screw 5 can drive the moving sleeve 8 to move up and down, thereby driving the connecting plate 9 and the small ejector blocks 12 to move upward, so that the small ejector blocks 12 protrude from the ejector blocks 10 and the micro air jet holes 13 are exposed. Then, it can be driven by the micro motor 701 and the rotating shaft 702 to rotate synchronously. The air pump 20 and several interconnected connecting pipes 19 inflate the interior of the small ejector block 12. The gas is ejected through the micro jet holes 13, thereby using the gas pressure to assist the separation between the lower mold 3 and the socket panel molding part inside it. The small ejector block 12 protrudes from the ejector block 10, so that the small ejector block 12 pre-ejects the socket panel molding part inside the lower mold 3. Then, the lifting plate 14 on the lower side of the ejector block 10 continues to move upward, which can drive the entire lifting plate 14 to move upward, thereby performing a full and sufficient ejection. Conversely, when the moving sleeve 8 moves downward, the connecting plate 9 first drives the small ejector block 12 to retract. When the lifting plate 14 moves down to the position of the blocking block 15, it can drive the entire blocking block 15 and ejector block 10 to move downward, so that the ejector block 10 retracts into the through hole in the lower wall of the lower mold 3, so as to facilitate the injection molding of the next socket panel. This completes the use process of the socket panel plastic mold with core pulling demolding mechanism.
