Description

Technical Field

[0001] This invention relates to the field of rubber manufacturing mold technology, specifically to a three-section automatic molding device for converting between vertical and horizontal operation of rubber products. Background Technology

[0002] A method for demolding a vulcanizing machine mold, disclosed in the prior art (CN115847672A), is described. The vulcanizing machine includes a base, several vertical guide columns connected to the base at their lower ends, a lower clamping plate sleeved on a sliding column, an upper clamping plate fixed to the upper end of the vertical guide columns, a lifting cylinder for driving the lower clamping plate to rise and fall, and a rubber mold located between the upper and lower clamping plates. The rubber mold includes an upper mold, a middle mold, and a lower mold. The lower clamping plate is located between the base and the upper clamping plate. The lifting cylinder is positioned between the base and the lower clamping plate, suspending both the middle and upper molds vertically on the upper clamping plate. When both the middle and lower molds are at their lowest positions, the middle mold separates from the lower mold in the vertical direction, thereby allowing the middle mold to detach from the upper mold by gravity. This method provides a method for demolding a vulcanizing machine mold that allows the middle mold to detach from the upper mold by its own weight, solving the problem of laborious manual separation of the middle mold from the upper mold during the existing rubber mold production process.

[0003] Although the above-mentioned device adopts a three-section mold structure to facilitate the demolding of the molded rubber products, the demolding method of the vulcanizing machine still has obvious defects in use: Although the mold of the device can be lifted and clamped by the clamping plate, the mold cannot change its vertical or horizontal position during the molding process. Due to the inability to change the vertical or horizontal position, the vulcanized material inside the mold cannot be evenly filled, resulting in poor quality of the molded rubber products. In addition, during the vulcanization molding process of the mold, kinetic energy clamping force still needs to be provided to the disassembly end of the mold body. Traditional vertical mold structures can achieve clamping of the upper and lower molds through hydraulic devices. However, for mold structures that need to change vertical or horizontal position and move during the molding process, traditional external telescopic hydraulic clamping devices cannot be used. Therefore, traditional vulcanizing mold structures cannot simultaneously maintain the clamping force of the mold structure while changing vertical or horizontal position, thus affecting the quality of the produced rubber products. Summary of the Invention

[0004] The purpose of this invention is to provide a three-section automatic molding device for converting between vertical and horizontal operation of rubber products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A three-section automatic molding device for converting rubber products from vertical to horizontal states includes a frame base, a main lifting mechanism, a rotating mechanism, a secondary lifting mechanism, and a mold body. The main lifting mechanism and the secondary lifting mechanism are both fixedly mounted on the frame base. The rotating mechanism is mounted on the main lifting mechanism. The mold body includes a three-section movable and separable upper mold, a middle mold, and a lower mold. The middle mold is provided with a gripping part for locking and limiting the movement of the upper and lower molds. The mold body is movablely engaged with the main lifting mechanism or the secondary lifting mechanism via a side-mounted rotating shaft, which drives the mold body to move up and down. When the mold body is movablely engaged with the main lifting mechanism, the rotating mechanism on the main lifting mechanism drives it to convert between vertical and horizontal states. The main lifting mechanism and the frame base are also provided with a bearing mechanism that corresponds to the upper mold or the lower mold when the mold body is open or closed.

[0007] Preferably, the frame base is provided with a translational slide groove, and a transfer base plate for supporting the lower mold is slidably arranged in the translational slide groove;

[0008] The main lifting mechanism includes a top frame and support columns fixedly connected to its four corners. The support columns are fixedly installed on the frame base on the side away from the top frame. The support columns are arranged in pairs on both sides of the translation slide groove. A pair of lifting optical shafts are also fixedly installed on both sides of the top frame on the translation slide groove. The lifting optical shafts on both sides of the top frame are synchronously lifted and slidably mounted with a top mold lifting plate that carries the upper mold through linear bearings.

[0009] The rotating mechanism includes a pair of rotating shaft seats, which are respectively mounted on rotating shaft seat mounting plates on both sides of the translation slide groove. The rotating shaft seat mounting plates on both sides are slidably sleeved on the lifting optical shafts on both sides of the main lifting mechanism through linear bearings. The rotating shaft seat mounting plates on both sides move synchronously in translation, lifting and sliding. The rotating shaft seats rotate in the horizontal or vertical direction under the drive of the rotating mechanism.

[0010] The auxiliary lifting mechanism includes fixed top plates arranged on both sides of a translational slide groove. Each of the fixed top plates is fixedly connected to the frame base via a pair of lifting optical shafts. Auxiliary lifting plates are synchronously lifted and slidably mounted on the lifting optical shafts on both sides of the fixed top plates via linear bearings. A rotating shaft seat is fixedly installed on each of the auxiliary lifting plates on both sides.

[0011] The transplanting base plate, the top mold lifting plate, the rotating shaft seat mounting plate, and the auxiliary lifting plate are driven by the sliding mechanism to slide horizontally or vertically.

[0012] Driven by the telescopic cylinder, the gripping part engages with or disengages from the upper and lower molds, thereby completing the engagement or disengagement of the upper and lower molds with the middle mold. The middle mold is fixedly installed with a mating rotating shaft on both sides of the translational slide groove. The mating rotating shaft is movably engaged with the rotating shaft seat or the rotating shaft seat.

[0013] The transplanting base plate drives the mold body to slide along the length of the translation slide. During the translation sliding process, the mold body moves by engaging with the rotating shaft and rotating shaft seat or rotating shaft seat. The lifting motion of the auxiliary lifting plate or rotating shaft seat mounting plate drives the middle mold to move up and down. During the engagement of the rotating shaft and rotating shaft seat of the mold body, the rotating mechanism drives the rotating shaft seat to rotate, thereby enabling the mold body to switch between vertical and horizontal positions. When the gripping part disengages from the upper mold and lower mold under the drive of the opening and closing telescopic cylinder, the upper mold and lower mold respectively engage with the top mold lifting plate or transplanting base plate to disengage from the middle mold.

[0014] Preferably, the sliding mechanism for driving the transplanting base plate, the top mold lifting plate, the rotating shaft mounting plate, and the auxiliary lifting plate to slide horizontally includes, but is not limited to, one or more combinations of screw sliding mechanism, pneumatic sliding mechanism, hydraulic sliding mechanism, or gear sliding mechanism.

[0015] Preferably, the sliding mechanism is a lead screw translation sliding mechanism, which includes a translation sliding lead screw. The transplanting base plate, the top mold lifting plate, the rotating shaft mounting plate, and the auxiliary lifting plate are all provided with lead screw seats that cooperate with the translation sliding lead screw. The translation sliding lead screw is connected to a servo motor. The rotation of the servo motors connected to each other drives the translation sliding lead screw to rotate, thereby driving the transplanting base plate, the top mold lifting plate, the rotating shaft mounting plate, or the auxiliary lifting plate to perform translation sliding.

[0016] Preferably, the rotating mechanism for driving the rotating shaft seat to rotate at a preset angle includes a servo rotary motor. The drive shaft of the servo rotary motor is connected to the power input end of the reducer, and the power output end of the reducer is fixedly connected to the shaft center of the rotating shaft seat. The rotating shaft seat is movably disposed within the rotating shaft seat, and the rotating shaft seat is fixedly mounted on a rotating shaft seat mounting plate. A motor rib is also fixedly mounted on the rotating shaft seat mounting plate, and the servo rotary motor and the reducer are fixedly mounted on the motor rib.

[0017] Preferably, a top mold lifting plate is fixedly installed on both sides of the upper surface of the upper mold. The top mold lifting plates on both sides are movably matched with the top mold lifting moving plate that is slidably lifted. Positioning pins are provided on both the transplanting base plate and the top mold lifting moving plate. Positioning holes that cooperate with the positioning pins are opened on the bottom of the lower mold and the top mold lifting plate.

[0018] Preferably, the telescopic cylinder is fixedly installed around the outside of the middle mold. The telescopic arms on the upper and lower sides of the telescopic cylinder are hinged to the opening and closing rotating shaft provided in the gripper part. The gripper part is installed through the assembly hole opened on the middle mold. During the telescopic movement of the telescopic cylinder, the telescopic arms of the telescopic cylinder extend and retract, pushing the opening and closing rotating shaft to extend and retract, thereby causing the gripper part's claw to engage or disengage with the surface of the upper or lower mold.

[0019] Preferably, the servo motors that drive the lifting plate of the top mold and the rotating seat of the shaft to move up, down, translate, and slide are all fixedly mounted on the top frame. Each of the drive shafts of the servo motors mounted on the top frame is fixedly mounted with a drive pulley. The drive pulleys are connected to their respective driven pulleys via belts. The driven pulleys are fixedly connected to the corresponding translation sliding screws that drive the lifting plate of the top mold or the rotating seat of the shaft. The rotation of the servo motors connected by belts drives the translation sliding screws on both sides to rotate synchronously, thereby driving the lifting plates of the top mold or the rotating seats of the shaft on both sides to move up and down synchronously.

[0020] Preferably, abutting cylinders are installed on one side of each of the two rotating shaft sleeves. One end of the telescopic arm of the abutting cylinder is fixedly connected to the assembly pin. When the mating rotating shaft mates with the rotating shaft sleeve, the abutting cylinder telescopically drives the assembly pin into the limiting hole opened on the side of the mating rotating shaft, thereby completing the locking and limiting of the mating rotating shaft.

[0021] Preferably, an injection manifold is fixedly installed on the outer side of the upper mold, and an injection nozzle communicating with the internal space of the middle mold is fixedly provided on one side of the injection manifold.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention provides an automatic vulcanizing mold forming device. The mold body can automatically change between vertical and horizontal states during the vulcanizing process. In the vertical state, it is convenient to open the mold and remove the parts, and prevents damage to the workpiece. In the horizontal state, it is used for injection and vulcanization, which greatly improves the quality stability of the product and the yield rate of the finished product. In addition, in order to maintain the kinetic energy clamping force of the mold body during the vulcanization process, this invention also provides a gripping part on the mold body. The gripping part continuously provides clamping force to the mold body during the transfer and vertical / horizontal state change, further ensuring the stability and yield rate of the product.

[0034] 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 merely partial embodiments of the present invention, and not embodiments of the entire invention. 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.

[0035] Please see Figure 1-9 The present invention provides a technical solution:

[0036] Example 1:

[0037] A three-section automatic molding device for converting between vertical and horizontal orientation of rubber products includes:

[0038] The frame base 1 has a translational slide 2 inside it, and the transplanting base plate 3 is slidably installed inside the translational slide 2.

[0039] The main lifting mechanism 4 includes a top frame 5 and four supporting columns 6 fixedly connected to its four corners. The supporting columns 6 are fixedly installed on the frame base 1 on the side away from the top frame 5. The supporting columns 6 are arranged in pairs on both sides of the translation slide 2. A pair of lifting optical shafts 7 are also fixedly installed on both sides of the top frame 5 on the translation slide 2. The top mold lifting moving plate 9 is synchronously lifted and slidably arranged on the lifting optical shafts 7 on both sides of the top frame 5 through linear bearings 8.

[0040] The rotating mechanism 10 includes a pair of rotating shaft seats 11. The rotating shaft seats 11 are respectively installed on the rotating shaft seat mounting plates 12 provided on both sides of the translation slide 2. The rotating shaft seat mounting plates 12 on both sides are slidably sleeved on the lifting optical shafts 7 on both sides of the main lifting mechanism 4 through linear bearings 8. The rotating shaft seat mounting plates 12 on both sides move synchronously in translation, lifting and sliding. The rotating shaft seats 11 rotate in the horizontal or vertical direction under the drive of the rotating mechanism.

[0041] The auxiliary lifting mechanism 13 includes fixed top plates 14 on both sides of the translation slide 2. The fixed top plates 14 on both sides are fixedly connected to the frame base 1 via a pair of lifting optical shafts 7. Auxiliary lifting plates 15 are synchronously lifted and slidably mounted on the lifting optical shafts 7 on both sides of the fixed top plates 14 via linear bearings 8. Rotary shaft seats 16 are fixedly installed on each of the auxiliary lifting plates 15.

[0042] The transplanting base plate 3, the top mold lifting plate 9, the rotating shaft seat mounting plate 12, and the auxiliary lifting plate 15 slide horizontally or vertically under the drive of the sliding mechanism; and,

[0043] The mold body 17 includes a three-section movable and interlocking upper mold 18, a middle mold 19, and a lower mold 20. The upper mold 18 and the lower mold 20 are respectively movable and engaged with the top mold lifting plate 9 or the transfer base plate 3. Both ends of the middle mold 19 are movably equipped with gripping parts 21 near the upper mold 18 and the lower mold 20. Driven by the opening and closing telescopic cylinder 23, the gripping parts 21 engage with or disengage from the upper mold 18 and the lower mold 20, thus completing the engagement or disengagement operation between the upper mold 18, the lower mold 20, and the middle mold 19. The middle mold 19 is also fixedly equipped with mating rotating shafts 22 on both sides of the translation slide 2. The mating rotating shafts 22 are movable and engaged with the rotating shaft seat 11 or the rotating shaft seat 16. Specifically…

[0044] The transplanting base plate 3 drives the mold body 17 to slide along the length of the translation slide 2. During the translation sliding process, the mold body 17 is in motion with the rotating shaft 22 and the rotating shaft seat 11 or the rotating shaft seat 16. The lifting movement of the auxiliary lifting plate 15 or the rotating shaft seat mounting plate 12 drives the middle mold 19 to lift. During the process of the rotating shaft 22 and the rotating shaft seat 11 of the mold body 17, the rotating mechanism drives the rotating shaft seat 11 to rotate, thereby enabling the mold body 17 to switch between vertical and horizontal positions. When the gripping part 21 disengages from the upper mold 18 and the lower mold 20 under the drive of the opening and closing telescopic cylinder 23, the upper mold 18 and the lower mold 20 respectively cooperate with the top mold lifting plate 9 or the transplanting base plate 3 to disengage from the middle mold 19.

[0045] In this embodiment, the frame base 1 serves as a support device for various components. A parallel translation groove is provided at its bottom, with a transfer base plate 3 movably mounted within the groove. This transfer base plate 3 cooperates with the lower mold 20 of the mold body 17, thereby causing the mold body 17 to slide and translate as the transfer base plate 3 moves. A main lifting mechanism 4 and a secondary lifting mechanism 13 are also provided along the movement path of the transfer base plate 3. The main lifting mechanism 4 is equipped with a top mold lifting plate 9, which cooperates with the upper mold 18 of the mold body 17. The lifting of the top mold lifting plate 9 drives the lifting of the upper mold 18, thus completing the mold opening operation of the mold body 17. Simultaneously, the lifting optical axis 7 of the main lifting mechanism 4... The mold body 17 is also equipped with a lifting and rotating mechanism 10. The rotating mechanism 10 has rotating bases 11 that mate with rotating shafts 22 on both sides of the mold body 17. The rotating bases 11 rotate under the drive of the drive mechanism. When the rotating shafts 22 mate with the rotating bases 11, the rotation of the drive mechanism causes the mold body 17 to rotate, thus allowing the mold body 17 to switch between vertical and horizontal states. In the vertical state, it facilitates mold opening and part removal, preventing workpiece damage. In the horizontal state, it performs injection molding and vulcanization, greatly improving product quality stability and finished product qualification rate. The switching between vertical and horizontal states improves product quality, and the change between these states does not require manual intervention, reducing the workload for operators. In addition to reducing the workload, the auxiliary lifting mechanism 13, as the supporting mechanism for the middle mold 19, fixes the middle mold 19 on the rotating shaft seat 16 on the auxiliary lifting plate 15 when the upper mold 18 and lower mold 20 are disengaged from the middle mold 19, thus facilitating the removal of the finished product inside the mold. To improve the stability of the fit between the middle mold 19 and the rotating shaft seat 16, abutment cylinders 37 are installed on one side of each rotating shaft seat 16. One end of the telescopic arm of the abutment cylinder 37 is fixedly connected to the assembly pin 38. When the mating rotating shaft 22 fits with the rotating shaft seat 16, the abutment cylinder 37 extends and retracts, driving the assembly pin 38 into the limiting hole opened on the side of the mating rotating shaft 22, thereby locking and limiting the mating rotating shaft 22. In this way, the middle mold 19 is secured on the rotating shaft seat. The locking limit on 16 prevents the middle mold 19 from detaching during the part removal process. Furthermore, in order to ensure the cooperation between the upper mold 18 and the top mold lifting plate 9, the top mold lifting plate 30 is also fixedly installed on both sides of the top of the upper mold 18. The top mold lifting plate 30 is lifted by the top mold lifting plate 9, thereby separating the upper mold 18 from the middle mold 19. At the same time, in order to ensure the accuracy of the cooperation between the top mold lifting plate 9 and the top mold lifting plate 30, and between the transfer base plate 3 and the lower mold 20, positioning pins 31 are provided on both the transfer base plate 3 and the top mold lifting plate 9. The bottom of the top mold lifting plate 30 and the lower mold 20 are respectively provided with positioning holes that cooperate with the positioning pins 31. The positioning pins 31 and the positioning holes cooperate to ensure the positioning accuracy during the separation and cooperation process.

[0046] Furthermore, to ensure that the mold body 17 can be converted between vertical and horizontal positions and facilitate mold opening, the mold body 17 needs to change its posture and position during injection molding and mold opening gaps. However, due to the movement of the mold body 17, the traditional hydraulic ejector pin closure method cannot meet the clamping force requirements of the device for the upper mold 18 and lower mold 20. Therefore, this application also specifically provides a clamping part 21 on the mold body 17. The clamping part 21 achieves the engagement, contact, or disengagement of the upper mold 18 and lower mold 20 during the extension and retraction of the telescopic cylinder 23. Specifically, the clamping part 21 mainly includes a clamp 33, as shown in the attached specification. Figure 1 and 7 During the extension and retraction of the telescopic cylinder 23, the latch 33 engages or disengages with the surface of the upper mold 18 or the lower mold 20, thereby achieving the self-locking operation of the mold body 17. This ensures that the mold body 17 continuously provides clamping force during transfer and flipping, further guaranteeing the quality of the product.

[0047] Since the movement modes of the transplanting base plate 3, the top mold lifting plate 9, the rotating shaft seat mounting plate 12, and the auxiliary lifting plate 15 in this application are relatively simple, and only need to achieve a stable translation and sliding function, the sliding mechanism includes, but is not limited to, one or more combinations of screw translation and sliding mechanism, pneumatic translation and sliding mechanism, hydraulic translation and sliding mechanism, or gear translation and sliding mechanism. The above-mentioned translation and sliding mechanisms are common in daily life and industrial systems and can be well applied in this embodiment.

[0048] Example 2:

[0049] The sliding mechanism is a lead screw translation sliding mechanism, which includes a translation sliding lead screw 24. The transplanting base plate 3, the top mold lifting plate 9, the rotating shaft seat mounting plate 12, and the auxiliary lifting plate 15 are all provided with lead screw seats 25 that cooperate with the translation sliding lead screw 24. The translation sliding lead screw 24 is connected to a servo motor 26. The rotation of the servo motor 26 drives the translation sliding lead screw 24 to rotate, thereby driving the transplanting base plate 3, the top mold lifting plate 9, the rotating shaft seat mounting plate 12, or the auxiliary lifting plate 15 to perform translation sliding.

[0050] The rotating mechanism that drives the rotating shaft seat 11 to rotate at a preset angle includes a servo rotary motor 27. The drive shaft of the servo rotary motor 27 is connected to the power input end of the reducer 28. The power output end of the reducer 28 is fixedly connected to the shaft center of the rotating shaft seat 11. The rotating shaft seat 11 is movably disposed in the rotating shaft sleeve 41. The rotating shaft sleeve 41 is fixedly installed on the rotating shaft seat mounting plate 12. A motor rib plate 29 is also fixedly installed on the rotating shaft seat mounting plate 12. The servo rotary motor 27 and the reducer 28 are fixedly installed on the motor rib plate 29.

[0051] In this embodiment, the sliding mechanism further selects a more stable and lower-cost lead screw translation sliding mechanism. The corresponding servo motor 26 drives the translation sliding lead screw 24 to move. Through the threaded engagement between the translation sliding lead screw 24 and the lead screw seat 25, the servo motor 26 drives the corresponding structure to perform translation sliding. The rotation drive mechanism of the rotating shaft seat 11 is a servo rotary motor 27. The rotation of the servo rotary motor 27 drives the reducer 28 to rotate, which in turn drives the mold body 17 to rotate, thereby realizing the change of the vertical and horizontal state of the mold body 17. The setting of the loss reduction machine 28 improves the torque and stability during the flipping process. A glue injection diversion plate 39 is fixedly installed on the outside of the upper mold 18. A glue injection nozzle 40 communicating with the internal space of the middle mold 19 is fixedly set on one side of the glue injection diversion plate 39. When in the horizontal state, the externally set injection device injects glue into the mold body 17 through the glue injection nozzle 40 and the glue injection diversion plate 39 to form the shape.

[0052] Example 3:

[0053] Servo motors 26, which drive the lifting platen 9 and the rotating base 11 of the top mold to move up, down, translate, and slide respectively, are all fixedly mounted on the top frame 5. Each of the drive shafts of the servo motors 26 mounted on the top frame 5 has a drive pulley 34 fixedly mounted on it. The drive pulleys 34 are connected to their respective driven pulleys 36 via belts 35. The driven pulleys 36 are fixedly connected to the corresponding translation sliding screws 24 that drive the lifting platen 9 or the rotating base 11 of the top mold. The rotation of the servo motors 26 connected by belts 35 drives the translation sliding screws 24 on both sides to rotate synchronously, thereby driving the lifting platen 9 or the rotating base 11 of the top mold to move up and down synchronously. The above-mentioned belt mechanism reduces the use of the servo motors 26 on both sides and improves the consistency of the movement of the translation sliding screws 24 on both sides, thereby ensuring the stability of the mold body 17 during the lifting process.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
