Description

Technical Field

[0001] The utility model relates to the technical field of automatic injection molding dies, and particularly relates to an automatic injection molding die. Background Art

[0002] In the automatic injection molding industry, as the core production tool, the accuracy and integrity of the die are directly related to the quality and production efficiency of the products. After the automatic injection molding process is completed, in order to perform die maintenance, replacement or cleaning, it is often necessary to disassemble the die from the injection molding machine. This operation is generally carried out by using a lifting device such as an overhead crane to ensure safety and efficiency. However, a technical problem existing in this process is that when the die is placed on the ground, due to the lack of effective buffer protection measures, the die often directly and rigidly contacts the ground. Such impact may not only damage the factory floor, such as cracks or depressions, but more importantly, it is very likely to cause damage to the die itself, such as corner breakage, displacement or damage of precision components, which will directly affect the service life of the die and the molding quality of subsequent products. For a long time, the solutions in the industry mostly rely on the experience and skills of operators to reduce the impact by slowly and carefully placing the die, but this cannot fundamentally solve the problem, and it is difficult to accurately control each time in actual operation. The die lowering efficiency is reduced.

[0003] After retrieval, for example, the existing Chinese patent publication number: CN214395198U injection molding die includes an upper fixing plate, a lower fixing plate, an upper template, a lower template, an upper die core and a lower die core. The upper fixing plate and the lower fixing plate are respectively installed on the corresponding machine tables. The upper die core and the lower die core are respectively installed on the upper fixing plate and the lower fixing plate through the corresponding upper template and lower template. When the upper template and the lower template are in the mold closing state, a cavity for injecting the rubber material is formed between the upper die core and the corresponding lower die core. A gate plate provided with a gate is vertically arranged on the same side of the upper template and the support plate. The upper template and the lower template are connected by at least four groups of grooves and protrusions in cooperation. The upper template and the lower template are connected by guide posts and guide post holes arranged at four corners of the upper template and the lower template in cooperation.

[0004] The cited patent literature also has the same problem. When the die is placed on the ground, due to the lack of effective buffer protection measures, the die often directly and rigidly contacts the ground. Such impact may not only damage the factory floor, such as cracks or depressions, but more importantly, it is very likely to cause damage to the die itself, such as corner breakage, displacement or damage of precision components, which will directly affect the service life of the die and the molding quality of subsequent products. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an automatic injection molding die aiming at the deficiencies of the prior art, and this automatic injection molding die can well solve the above problems.

[0006] To meet the above requirements, the technical solution adopted by the present utility model to solve its technical problems is:

[0007] Provide an automatic injection molding die, including a moving die and a fixed die that are clamped together. Shock-absorbing and buffering components are embedded and movably installed on the bottom surfaces of the moving die and the fixed die. Rectangular installation grooves are longitudinally opened at the middle positions of the bottom surfaces of the moving die and the fixed die. The shock-absorbing and buffering components include lifting blocks slidably connected in the rectangular installation grooves, lifting support plates arranged below the lifting blocks and slidably connected in the rectangular installation grooves, and multiple hydraulic buffer dampers fixedly and symmetrically installed on the top surfaces of the lifting support plates. The top damping ends of each hydraulic buffer damper are fixedly installed on the bottom surface of the lifting block. The top surface of each lifting block is embedded and connected to the inside of the moving die and the fixed die through hydraulic lifting columns. Limiting insertion rods are inserted centripetally on the outer walls of both sides of the moving die and the fixed die. One end of each limiting insertion rod is sleeved with a compression spring on the moving die and the fixed die. When the lifting block descends, the inner end of the limiting insertion rod slides and contacts the outer wall of the lifting block. Plugging holes for the limiting insertion rod to be centripetally squeezed and inserted through the compression spring are opened on the upper parts of the outer walls on both sides of the lifting block.

[0008] Preferably in this solution, a buffer spring is sleeved on the periphery of each hydraulic buffer damper, and the upper and lower ends of the buffer spring are elastically abutted against the top surface of the lifting support plate and the bottom surface of the lifting block respectively;

[0009] A rubber buffer and shock-absorbing pad is bonded to the bottom surface of the lifting support plate.

[0010] Preferably in this solution, two anti-falling support blocks are symmetrically installed on the top surface of the lifting support plate, and a spacing is reserved between the top surface of the anti-falling support block and the bottom surface of the lifting block.

[0011] Preferably in this solution, an extension groove is upwardly extended and opened on the inner top wall of the rectangular installation groove, and the tail end seat of the hydraulic lifting column is installed on the inner top wall of the extension groove through bolts.

[0012] Preferably in this solution, multiple positioning vertical rods are installed on the top surface of the lifting block in a rectangular structure distribution, and the positioning vertical rods are longitudinally inserted into the moving die and the fixed die.

[0013] Preferably in this solution, inner sunken hole grooves for installing the limiting insertion rods and the compression springs are horizontally opened on both inner walls of the rectangular installation groove and in the moving die and the fixed die.

[0014] Preferably, a first limiting ring is welded to the outer wall on the circumferential side of the head end of each limiting insertion rod, and a second limiting ring is welded to the outer wall on the circumferential side of the limiting insertion rod near the free tail end;

[0015] The extrusion spring is sleeved between the first limiting ring and the second limiting ring and is located on the circumferential side of the limiting insertion rod.

[0016] Preferably, a threaded hole is formed in the outer wall of the head end of the limiting insertion rod, and a T-shaped pull rod is dynamically threadedly connected in the threaded hole.

[0017] Preferably, adjustable support rods are arranged on the bottom surfaces of the moving die and the fixed die. An extension column is arranged at the top end of the adjustable support rod, and the extension column is welded to the bottom surfaces of the moving die and the fixed die.

[0018] Preferably, a concave hole is formed in the top surface of the adjustable support rod. A screw rod is integrally connected to the bottom surface of the extension column and is threadedly connected in the concave hole. A support spring is arranged on the outer side of the screw rod and in the concave hole.

[0019] The beneficial effects of the present utility model are as follows:

[0020] For this automatic injection molding die, through the combined action of the hydraulic buffer damper, buffer spring, lifting block, and lifting support plate of the shock absorption and buffer assembly, it can effectively absorb and disperse the impact force during the falling process of the die, significantly reducing problems such as die breakage, corner cracking, or displacement of precision components caused by directly hitting the ground, prolonging the service life of the die, and reducing the maintenance cost;

[0021] The innovative design of the limiting insertion rod and the extrusion spring not only provides additional stability during the falling process of the die but also ensures accurate positioning during the descending process of the die through the insertion mechanism at the free tail end, reducing the operation difficulty and safety risks, and improving the controllability and safety of the operation.

[0022] The free tail end of the limiting insertion rod abuts against the outer wall of the lifting block. When the lifting block descends, the free tail end frictionally slides on the outer wall of the lifting block. When the free tail end contacts the insertion hole, the free tail end is inserted into the insertion hole. At the same time, the extrusion spring releases the contraction extrusion force, causing the extrusion spring to stretch and elastically abut against the second limiting ring, increasing the stability of the free tail end inserted into the insertion hole.

[0038] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0039] This embodiment discloses an automated injection molding die as Figures 1 to 7 shown, which includes a movable die 1 and a fixed die 2 that are clamped together. Shock-absorbing and buffering components are movably installed inside the bottom surfaces of the movable die 1 and the fixed die 2. Rectangular installation grooves 8 are longitudinally formed in the middle positions of the bottom surfaces of the movable die 1 and the fixed die 2. Removable maintenance plates 4 are installed on both outer sides of the movable die 1 and the fixed die 2 through screws on both sides of the rectangular installation groove 8. Operation control panels 6 are installed on both outer sides of the movable die 1 and the fixed die 2 above the removable maintenance plates 4. Operation buttons are provided on the surfaces of the operation control panels 6. Mold cavities 7 are provided inside both the movable die 1 and the fixed die 2.

[0040] In this embodiment, the rectangular installation grooves 8 on the bottom surfaces of the movable die 1 and the fixed die 2 provide installation spaces for the lifting blocks 10 and the lifting support plates 17, ensuring that these buffering components can be stably integrated inside the die and providing a basic framework for the entire buffering structure.

[0041] In this embodiment, the shock absorption and buffering assembly includes a lifting block 10 slidably connected in a rectangular installation groove 8, a lifting support plate 17 disposed below the lifting block 10 and slidably connected in the rectangular installation groove 8, and a plurality of hydraulic buffer dampers 11 fixedly and symmetrically installed on the top surface of the lifting support plate 17. The top damping end of each hydraulic buffer damper 11 is fixedly installed on the bottom surface of the lifting block 10. The top surface of each lifting block 10 is internally connected to the inside of the moving die 1 and the fixed die 2 through a hydraulic lifting column 12. Limiting insertion rods 5 are inserted into the outer walls of both sides of the moving die 1 and the fixed die 2 in a centripetal manner. One end of each limiting insertion rod 5 located in the moving die 1 and the fixed die 2 is sleeved with a compression spring 22. When the lifting block 10 descends, the inner end of the limiting insertion rod 5 slides and contacts the outer wall of the lifting block 10. Plugging holes 14 for the limiting insertion rods 5 to be centripetally pressed and inserted through the action of the compression spring 22 are provided on the upper parts of the outer walls on both sides of the lifting block 10.

[0042] In this embodiment, the limiting insertion rod 5 is used to provide auxiliary positioning and buffering support when the lifting block 10 descends. Its free tail end 21 is inserted into the plugging hole 14 after the lifting block 10 descends through the action of the compression spring 22, enhancing stability, preventing excessive shaking of the mold, and at the same time serving as an auxiliary tool for manually adjusting the lifting block 10. The lifting block 10 is connected to the inside of the moving die 1 and the fixed die 2 through the hydraulic lifting column 12, and can absorb and disperse the impact force when the moving die 1 and the fixed die 2 are lowered, avoiding direct impact on the ground and protecting the mold and the ground from damage. The hydraulic buffer dampers 11 are installed between the lifting block 10 and the lifting support plate 17, and slowly release the falling energy through their damping characteristics, effectively slowing down the descending speed of the mold, reducing the impact, and protecting the precision components of the mold.

[0043] In this embodiment, the plugging hole 14 allows the free tail end 21 of the limiting insertion rod 5 to be inserted at an appropriate time, increasing the stability and controllability during the descending process of the mold. The buffer spring 15 surrounds the hydraulic buffer damper 11, providing an additional buffering effect and further absorbing the falling impact.

[0044] In this embodiment, a buffer spring 15 is sleeved on the periphery of each hydraulic buffer damper 11. The upper and lower ends of the buffer spring 15 are elastically abutted against the top surface of the lifting support plate 17 and the bottom surface of the lifting block 10 respectively. A rubber buffer and shock absorption pad 18 is bonded to the bottom surface of the lifting support plate 17. Two anti-falling support blocks 16 are symmetrically installed on the top surface of the lifting support plate 17, and a spacing is reserved between the top surface of the anti-falling support block 16 and the bottom surface of the lifting block 10. The anti-falling support blocks 16 are located at the top of the lifting support plate 17 and maintain a certain spacing from the lifting block 10. As the last line of defense, they prevent sudden falling and ensure a smooth landing.

[0045] In this embodiment, the rubber buffer and shock absorption pad 18 is bonded to the bottom of the lifting support plate 17, directly contacting the ground, further absorbing the remaining impact force and protecting the ground from damage.

[0046] In this embodiment, an extension groove 9 is formed by upward extension of the inner top wall of the rectangular installation groove 8. The tail seat of the hydraulic lifting column 12 is installed on the inner top wall of the extension groove 9 by bolts. A plurality of positioning vertical rods 13 are installed on the top surface of the lifting block 10 in a rectangular structure distribution. The positioning vertical rods 13 are longitudinally inserted into the moving die 1 and the fixed die 2. The positioning vertical rods 13 ensure the correct lifting and positioning position of the lifting block 10 inside the mold, and increase the stability of the overall structure.

[0047] In this embodiment, inner sunken hole grooves 25 for installing the limit insertion rods 5 and the compression springs 22 are transversely formed on both inner side walls of the rectangular installation groove 8 and are located in the moving die 1 and the fixed die 2. A first limit ring 19 is welded to the outer wall of the circumferential side of the head end of each limit insertion rod 5. A second limit ring 20 is welded to the outer wall of the circumferential side of the limit insertion rod 5 near the free tail end 21. The compression spring 22 is sleeved between the first limit ring 19 and the second limit ring 20 and is located on the circumferential side of the limit insertion rod 5. The free tail end 21 of the limit insertion rod 5 abuts against the outer wall of the lifting block 10. When the lifting block 10 descends, the free tail end 21 frictionally slides on the outer wall of the lifting block 10. When the free tail end 21 contacts the insertion hole 14, the free tail end 21 is inserted into the insertion hole 14. At the same time, the compression spring 22 releases the contraction extrusion force, so that the compression spring 22 extends to elastically abut against the second limit ring 20, increasing the stability of the free tail end 21 inserted into the insertion hole 14.

[0048] In this embodiment, the first limit ring 19, the second limit ring 20 and the compression spring 22 together provide a pre-tightening force for the limit insertion rod 5, ensuring the stable sliding of the limit insertion rod 5 on the outer wall of the lifting block 10 and the accurate insertion into the insertion hole 14. The compression spring 22 provides an inward extrusion force for the limit insertion rod 5 through compression deformation, helping to control and stabilize the process of lowering the mold.

[0049] In this embodiment, a threaded hole 24 is formed in the outer wall of the head end of the limit insertion rod 5, and a T-shaped pull rod 23 is dynamically threadedly connected in the threaded hole 24. When the lifting block 10 needs to be lifted into the rectangular installation groove 8, it is necessary to pull the limit insertion rod 5 out of the insertion hole 14. For this purpose, the T-shaped pull rod 23 is threadedly connected to the threaded hole 24 of the limit insertion rod 5, so as to help pull the limit insertion rod 5 and limit it in the inner sunken hole groove 25.

[0050] In this embodiment, adjustable support rods 3 are provided at the bottom surfaces of the moving mold 1 and the fixed mold 2. An extension column 26 is provided at the top end of the adjustable support rod 3. The extension column 26 is welded to the bottom surfaces of the moving mold 1 and the fixed mold 2. A concave hole 27 is formed in the top surface of the adjustable support rod 3. A screw rod 28 that is integrally connected to the bottom surface of the extension column 26 and is threadedly connected in the concave hole 27 is provided. A support spring 29 is provided on the outer side of the screw rod 28 and within the concave hole 27. The support spring 29 is located outside the screw rod 28 and within the concave hole 27 to provide certain elastic support for the adjustable support rod 3, ensuring stable support. The height of the adjustable support rod 3 can be adjusted by rotating the thread around the screw rod 28. The height of the adjustable support rod 3 can be adjusted according to actual needs. At the same time, the bottom surface of the adjusted adjustable support rod 3 is higher than the bottom surface of the lifting support plate 17. In this way, when the lifting support plate 17 falls to the ground for buffering, the adjustable support rod 3 can assist in supporting the moving mold 1 and the fixed mold 2. It can also rotate the bottom surface of the adjustable support rod 3 to fall to the ground for auxiliary support after the lifting support plate 17 falls to the ground.

[0051] In addition, in order to prevent the in-mold injection inserts from being skewed or loosened due to vibration, a visual inspection camera can be further added to the fixed mold to be used for on-line detecting the positions of the components in the mold to ensure injection accuracy. Moreover, it can also be used for detecting and positioning the opening and closing positions and trajectories of the mold during the mold parting movement, so as to send a warning to the rear tire system when the mold does not conform to the set scenario, achieving the purpose of protection, and further realizing the automatic injection molding of the mold.

[0052] A PLC for opening and closing the hydraulic lifting column 12 is installed inside the operation control panel 6. The PLC model can be selected according to actual needs. In the present utility model, the PLC model is S7-200, which has the advantages of high reliability, strong anti-interference ability and convenient maintenance.

[0053] Working principle:

[0054] After the automatic injection molding mold completes the injection molding process, it is ready to be disassembled from the injection molding machine. At this time, the buffer structures of the present technical solution have been built into the bottoms of the moving mold 1 and the fixed mold 2 of the mold. Shock-absorbing and buffering components are movably installed in the bottoms of the moving mold and the fixed mold. An operator uses a crane to lift the mold. At this time, the hydraulic lifting column 12 at the bottom of the mold is in a retracted state, so that the entire shock-absorbing and buffering component is in the initial position where it is not opened. The mold slowly descends under the guidance of the crane. As the mold lands on the ground, the operator gradually lowers the hydraulic lifting column 12 through the control button, allowing the lifting block 10 to slowly descend under the combined action of the hydraulic buffer damper 11 and the buffer spring 15. The hydraulic buffer damper 11 gradually consumes the falling energy through the resistance generated by the flow of the liquid inside it to control the descending speed, and the buffer spring further absorbs the remaining impact force.

[0055] During the downward movement of the lifting block 10, under the action of the extrusion springs 22 on both sides of the mold, the centripetal pressure is applied to the lifting block 10. The free tail ends 21 of the limit insertion rods 5 come into contact with the outer wall of the lifting block 10 and slide until the free tail ends 21 touch and insert into the insertion holes 14 on the lifting block 10. At this time, the extrusion springs 22 start to release pressure, providing more stable support for the limit insertion rods 5 to ensure the positioning accuracy when the mold descends. Before the mold completely lands, the distance reserved between the anti-falling support block 16 and the lifting block 10 will gradually decrease, and finally achieve a gentle landing. The rubber buffer shock-absorbing pad 18 further absorbs the last tiny impact, ensuring that almost no impact force is transmitted when the mold contacts the ground, protecting the mold and the ground from damage. When the mold needs to be reloaded back into the injection molding machine, the limit insertion rods 5 can be easily lifted by the threaded connection between the T-shaped pull rod 23 and the limit insertion rods 5, releasing their restriction on the lifting block 10. Subsequently, through the upward movement of the hydraulic lifting column 12, the entire shock-absorbing and buffering assembly is reset to the initial state, facilitating the hoisting and installation of the mold.
