Description

Technical Field

[0001] The invention relates to the technical field of production of plastic products, in particular to a vulcanization device. Background Art

[0002] Vulcanization equipment is mainly used for vulcanization of materials such as rubber and plastic. It causes chemical reactions inside the material through heating and pressurization to achieve the desired physical and chemical properties.

[0003] The Chinese patent application with publication number CN113246352A discloses a vulcanization device for new material production and processing, including a mounting frame, a placement frame and a cover plate, wherein the placement frame is fixedly mounted on the mounting frame, and the cover plate is located above the placement frame and vertically slidably connected to the placement frame. The placement frame is provided with a plurality of first guide sleeves evenly distributed along its circumference, a first slide rod is slidably penetrated in the first guide sleeve, the first slide rod is connected to the first guide sleeve by a first spring, and a positioning rod is welded to one end of the first slide rod away from the first guide sleeve.

[0004] When the vulcanization equipment is in use, the staff first pushes the positioning rod to slide to the outside of the placement frame, and the first spring is compressed. Then, the new material to be vulcanized is placed in the placement frame. After placement, the staff releases the positioning rod. Under the elastic force of the first spring, the first slide rod and the first positioning rod move inward, and the multiple first positioning rods clamp and fix the new material to be vulcanized. Under the action of the first spring, the first positioning rod has the function of elastic expansion and contraction, so that the first positioning rod has the ability to fix new materials of different sizes and shapes.

[0005] However, in actual implementation, the vulcanization equipment still has some shortcomings: the first positioning rod fixes the new material elastically, and under accidental interference from external forces, the new material may shake, thereby deviating from the working position and affecting the vulcanization effect. Summary of the invention

[0006] The present invention provides a vulcanization device, aiming to solve the problem in the related art that the first positioning rod fixes the new material elastically and has poor stability during fixation.

[0007] The vulcanization equipment of the present invention comprises a workbench and a vulcanization mechanism. There are a plurality of vulcanization mechanisms and they are distributed on the workbench. The vulcanization mechanism comprises a lower mold, an upper mold, a clamping unit and a driving member. The lower mold is disc-shaped and installed on the workbench, and the upper mold is connected to the workbench through a lifting device. There are a plurality of clamping units and they are arranged at intervals along the circumference of the lower mold. The clamping unit comprises an active slide, a passive slide and a clamping claw for clamping the vulcanized material. The active slide and the passive slide are both assembled on the lower mold along the radial sliding direction of the lower mold. The active slide is provided with a wedge-shaped portion, and the passive slide is elastically slidably connected with a wedge-shaped block. A clamping member is assembled in the passive slide along the horizontal direction, and a pushing member is provided between the clamping member and the wedge-shaped block. When the wedge-shaped block slides, the clamping member can be pushed to slide by the pushing member. The lower mold is provided with a plurality of slots for the clamping member to be inserted and arranged at intervals along the sliding direction of the passive slide. The clamping claw is connected to the passive slide. The driving member is connected to the plurality of active slides to drive the plurality of active slides to slide synchronously.

[0008] When the driving member drives multiple active slides to slide synchronously, the active slide can slide with the wedge-shaped portion toward the wedge block until it contacts the wedge block. Under the pushing action of the wedge-shaped portion, the wedge block will slide with the passive slide and the clamp. When the clamp clamps the material to be vulcanized, the sliding of the clamp stops. The wedge-shaped portion will push the wedge block to slide upward, and the wedge block will push the clamp to slide to the outside of the passive slide through the pushing member. When the clamp extends out of the passive slide, the clamp can be engaged in the slot, thereby locking the position of the passive slide and the clamp, so that the clamp's clamping of the material is converted into a rigid clamp. In this way, even under the interference of external forces, the clamp and the material cannot shake, which improves the stability of the clamp when fixed and ensures the subsequent vulcanization effect of the material.

[0009] Preferably, the pushing member includes a push bar slidably assembled in the passive sliding seat, the sliding direction of the push bar is parallel to the sliding direction of the wedge block and perpendicular to the sliding direction of the card; the wedge block is provided with a pushing member, when the wedge block slides with the pushing member, the pushing member can push the push bar to slide toward the card, a wedge structure is provided between the push bar and the card, when the push bar slides toward the card, the wedge structure can push the card to slide to the outside of the passive sliding seat, so that the card is engaged in the card slot.

[0010] Preferably, the wedge-shaped structure includes a first wedge-shaped surface provided on the push bar and a second wedge-shaped surface provided on the clamping member, and when the push bar slides toward the clamping member, the first wedge-shaped surface can fit with the second wedge-shaped surface.

[0011] The push bar and the wedge structure realize the driving of the wedge block toward the clamping piece, ensuring the smooth outward movement of the clamping piece.

[0012] Preferably, a locking groove is provided on the card, and a locking strip is elastically slidably connected in the passive slide seat. In the initial state, the locking strip elastically presses against the card, and when the card is engaged in the slot, the locking strip is aligned with the locking groove and engaged in the locking groove.

[0013] When the card is engaged in the card slot, the locking strip is used to lock the position of the card to prevent it from retreating and falling out of the card slot.

[0014] Preferably, the passive sliding seat includes an outer seat and an inner seat, the outer seat has a cavity inside, the push strip, the clamp and the locking strip are elastically slidably connected to the outer seat; the inner seat is arranged in the cavity and can slide, the wedge block is elastically slidably connected to the inner seat, and the locking strip is provided with a protrusion protruding into the cavity; when the wedge-shaped part returns to its original position, it can push the wedge block to move back, and the wedge block slides with the inner seat toward the protrusion so that the inner seat can squeeze the locking strip through the protrusion.

[0015] When the wedge block moves back, the inner seat can slide in the cavity to squeeze the protrusion and the locking strip, so that the locking strip withdraws from the locking groove, so that the card is unlocked and retracted under the action of elastic force, thereby unlocking the passive slide and the clamp, and facilitating the synchronous movement of the passive slide and the clamp back.

[0016] Preferably, both the outer seat and the inner seat are provided with through holes, and the lower mold is provided with a wedge strip extending along the sliding direction of the passive slide seat. When the wedge block moves back to its original position, the wedge strip passes through a plurality of the through holes in sequence and contacts the wedge block. Under the action of the wedge strip, the wedge block moves up and avoids the wedge portion.

[0017] During the resetting process of the wedge block, the wedge bar is used to lift the wedge block, so that the wedge block can avoid the wedge portion, making it easier for the wedge portion to pass through and reset.

[0018] Preferably, a connecting rod is provided between the clamping jaw and the outer seat, one end of the connecting rod is connected to the outer seat, and the other end is provided with a mounting groove, and the clamping jaw has a protrusion, which extends into the mounting groove and is hinged to the connecting rod.

[0019] Preferably, both clamping ends of the clamping jaw are provided with rotatable rolling elements.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0023] The present invention enables the clamp to automatically clamp the material to be vulcanized by arranging the driving member, the active slide, the passive slide and the clamp. The clamping process of each clamp has a certain degree of independence, so that each clamp can be used to clamp materials of regular shapes as well as materials of irregular shapes. At the same time, the clamp can also clamp materials of different sizes, and has strong adaptability. In addition, the clamp position is locked by the clamping action of the clamp and the slot, so that the clamp clamping of the material becomes rigid clamping, which enhances the stability of the clamp when clamping the material, avoids the shaking and displacement of the material, and ensures the subsequent vulcanization effect.

[0042] A support plate 101 a is provided above the workbench 101 , and four corners of the support plate 101 a are connected to the workbench 101 through vertical rods 101 b .

[0043] The lower die 102 is disc-shaped and mounted on the workbench 101. The upper die 103 is located above the lower die 102 and connected to the workbench 101 through a lifting device. The lifting device includes any one of a screw nut mechanism, a gear rack mechanism, an electric push rod, and a hydraulic cylinder.

[0044] Taking the lead screw and nut mechanism as an example, the lifting device includes a lead screw 101c, a nut 101f and a lifting platform 101e. The lead screw 101c is vertically arranged between the support plate 101a and the workbench 101, and the two ends are respectively connected to the support plate 101a and the workbench 101 for rotation; the support plate 101a is provided with a power motor 101d for driving the lead screw 101c to rotate. The lifting platform 101e is provided with a plurality of through holes, and the lifting platform 101e is sleeved on the lead screw 101c and the four vertical rods 101b through the plurality of through holes. The lead screw 101c is threaded with a nut 101f, and the nut 101f is connected to the lifting platform 101e for rotation. The upper mold 103 is installed below the lifting platform 101e. It should be noted that in this embodiment, the number of the lead screw 101c and the power motor 101d can be one, two or other numbers, etc., which are not limited here.

[0045] See also Figure 2 and Figure 3 There are multiple clamping units 104 and they are arranged at equal intervals along the circumference of the lower mold 102. The clamping units 104 include an active slide 1, a passive slide 2 and a clamping claw 3.

[0046] The part close to the outer side of the lower mold 102 forms an annular portion 102a, and the interior of the annular portion 102a is hollow. The active slide 1 and the passive slide 2 are both arranged in the annular portion 102a, and the active slide 1 is located below the passive slide 2. The active slide 1 can slide along the radial direction of the lower mold 102, and a guide rail 102b extending along the radial direction of the lower mold 102 is fixed in the annular portion 102a, and the passive slide 2 is slidably fitted in the guide rail 102b.

[0047] See also Figures 2 to 6, the passive slide 2 includes an outer seat 21 and an inner seat 22. The outer seat 21 is slidably arranged on the guide rail 102b, the clamping jaw 3 is placed above the lower die 102 and is located on the side of the outer seat 21 facing the axis of the lower die 102, a connecting rod 4 is arranged between the clamping jaw 3 and the outer seat 21, one end of the connecting rod 4 is fixedly connected to the outer seat 21 through a vertical fixing rod, and the other end is provided with a mounting groove 41, the clamping jaw 3 has a protrusion 31, the protrusion 31 extends into the mounting groove 41, and is hinged to the connecting rod 4 through a vertical support shaft, so that the clamping jaw 3 can be slightly deflected when clamping the workpiece, thereby improving the flexibility during clamping. In addition, both clamping ends of the clamping jaw 3 are provided with a rotatable rolling member 32. The rolling member 32 reduces the friction force when the clamping jaw 3 contacts the workpiece, so that the clamping action of the clamping jaw 3 on the workpiece is smoother. In this embodiment, the rolling member 32 can be a smaller roller, a ball, etc.

[0048] See also Figure 2 , Figure 3 , Figure 6 and Figure 7 The outer seat 21 has a cavity inside, and both side walls of the cavity are provided with a slide groove 211 extending along the radial direction of the lower mold 102. The inner seat 22 is arranged in the cavity and is provided with two sliding members 221. The two sliding members 221 are respectively slidably matched in the two slide grooves 211. In the initial state, the sliding member 221 is located at one end of the slide groove 211 close to the axis of the lower mold 102, and the inner seat 22 is in contact with the wall surface of the cavity close to the axis of the lower mold 102. In this embodiment, the shape of the sliding member 221 can be a block, a rod, a column, etc., which is not limited here.

[0049] The inner seat 22 is a frame-shaped structure, and a wedge block 222 is vertically slidably fitted inside. A compression spring 223 is connected between the top of the wedge block 222 and the inner seat 22. In normal state, the wedge block 222 protrudes downward from the inner seat 22. A wedge portion 11 is fixed on the active slide 1. In the initial state, the wedge portion 11 is located on the side of the wedge block 222 away from the axis of the lower mold 102.

[0050] The outer seat 21 is equipped with a clamp 212 along the tangential sliding of the lower mold 102, and a return spring 213 is connected between the clamp 212 and the outer seat 21. In this embodiment, the shape of the clamp 212 can be a block, a strip, a rod, etc. A pusher is provided between the clamp 212 and the wedge block 222.

[0051] Specifically, the pusher includes a push bar 214, which is vertically slidably assembled on the outer seat 21, and its sliding direction is perpendicular to the sliding direction of the clamp 212, and a return spring 215 is connected between the push bar 214 and the outer seat 21. A pusher is fixed on the wedge block 222, and the pusher can be a push rod 222a located directly below the push bar 214. When the wedge block 222 slides upward, the push rod 222a can contact the push bar 214 and push the push bar 214 to slide toward the clamp 212, and a wedge structure is provided between the push bar 214 and the clamp 212.

[0052] The wedge structure includes a first wedge surface 214a provided on the push bar 214 and a second wedge surface 212a provided on the clamping member 212. When the push bar 214 slides toward the clamping member 212, the first wedge surface 214a can fit with the second wedge surface 212a. At the same time, the push bar 214 can push the clamping member 212 to slide through the fit of the first wedge surface 214a and the second wedge surface 212a, and the clamping member 212 gradually extends out of the outer seat 21. A plurality of card slots 102c are provided on the guide rail 102b, and the plurality of card slots 102c are arranged at equal intervals along the sliding direction of the passive slide 2. After the clamping member 212 extends out of the outer seat 21, it can fit in one of the card slots 102c.

[0053] In other embodiments, the push member may include a push column, a push rod or a push block, which is a replacement form of the push bar 214. Taking the push block as an example, the wedge-shaped structure between it and the clamping member 212 may include a wedge-shaped surface, which may be provided on the push block or on the clamping member 212. When the push block slides toward the clamping member 212, the clamping member 212 may also achieve the effect of sliding outward under the inclined guidance of the wedge-shaped surface. In addition, in another implementation, the wedge-shaped structure may include an arc-shaped surface, which is similar to the arrangement form of the above-mentioned wedge-shaped surface, and it may also help the clamping member 212 to slide outward.

[0054] See also Figure 2 , Figure 6 and Figure 7 It should be noted that the clamping member 212 is provided with a locking groove 212b, and the outer seat 21 is slidably equipped with a locking strip 216, the sliding direction of the locking strip 216 is consistent with the sliding direction of the passive slide 2, and a thrust spring 217 is connected between the locking strip 216 and the outer seat 21. In the initial state, the locking strip 216 elastically presses against the surface of the clamping member 212, and when the clamping member 212 is engaged in the clamping groove 102c, the locking strip 216 is aligned with the locking groove 212b, and under the action of the thrust spring 217, the locking strip 216 is engaged in the locking groove 212b.

[0055] The locking strip 216 is provided with a protrusion 216a protruding into the cavity, and the protrusion 216a is located on the side of the inner seat 22 away from the axis of the lower mold 102. When the wedge-shaped portion 11 returns to its original position, it can move the wedge block 222 back through the straight surface of the wedge block 222, and the wedge block 222 slides with the inner seat 22 toward the protrusion 216a, so that the inner seat 22 can squeeze the locking strip 216 through the protrusion 216a, so that the locking strip 216 is withdrawn from the locking groove 212b. After the locking strip 216 is withdrawn, the clamping member 212 is disengaged from the clamping groove 102c and retracted under the action of the return spring 213.

[0056] See also Figure 3 and Figure 6 It should be noted that both the outer seat 21 and the inner seat 22 are provided with through holes, and the lower mold 102 is provided with a wedge strip 102d extending along the sliding direction of the passive slide 2. When the wedge block 222 moves back to the original position with the passive slide 2, the wedge strip 102d passes through the multiple through holes in sequence and contacts the wedge block 222. Under the action of the wedge strip 102d, the wedge block 222 moves up and avoids the wedge portion 11, and the wedge portion 11 is able to pass over the wedge block 222 and move to the original position.

[0057] See also Figures 1 to 3 The driving member 105 is connected to the multiple active slides 1 to drive the multiple active slides 1 to slide synchronously.

[0058] Specifically, the driving member 105 includes a screw rod 105 a and a driving motor 105 b .

[0059] The number of screw rods 105a is equal to and corresponds to the number of active slides 1. The screw rods 105a extend along the sliding direction of the corresponding active slides 1 and are rotatably mounted on the inner side of the annular portion 102a. The active slides 1 are threadedly connected to the corresponding screw rods 105a. A bevel gear 105c is mounted on one end of the screw rods 105a.

[0060] A bevel gear 105d is rotatably mounted inside the annular portion 102a, and the bevel gear 105d meshes with each of the plurality of bevel gears 105c. A driving motor 105b is mounted on the annular portion 102a and connected to the bevel gear 105d via a gear pair mechanism 105e to drive the bevel gear 105d to rotate.

[0061] refer to Figures 1 to 7 , the workflow of the vulcanization equipment of the present invention is:

[0062] First, the operator places the material to be vulcanized on the lower mold 102. The driving motor 105b drives the bevel gear plate 105d to rotate through the gear pair mechanism 105e, and the bevel gear plate 105d drives the multiple screws 105a to rotate synchronously through the bevel gear 105c. The screws 105a drive the active slide 1 to move toward the axis of the lower mold 102. When the wedge-shaped portion 11 on the active slide 1 contacts the wedge block 222, the wedge-shaped portion 11 pushes the wedge block 222 to slide together, and the wedge block 222 slides together with the passive slide 2 and the clamp 3, so that the multiple clamps 3 will synchronously approach the material to be vulcanized.

[0063] When the material is irregular in shape, the clamping jaw 3 of one clamping unit 104 will first contact and clamp the material, and the clamping jaw 3 will also be blocked by the material itself, and its sliding stops. For ease of understanding, the clamping unit 104 is used as an example for subsequent description.

[0064] When the sliding of the clamping jaw 3 stops, the driving motor 105b does not stop, and the active slide 1 will continue to move with the wedge-shaped portion 11, and the wedge-shaped portion 11 will squeeze the wedge block 222, and the wedge block 222 will gradually retract upward into the inner seat 22. When the wedge block 222 moves upward, it will drive the push rod 222a to move upward, and the push rod 222a will gradually contact the push bar 214 and push the push bar 214 to move upward, and the push bar 214 will drive the first wedge surface 214a to gradually approach the second wedge surface 212a, until the first wedge surface 214a and the second wedge surface 212a fit. Then, the push bar 214 squeezes the clamping member 212 through the first wedge surface 214a and the second wedge surface 212a, and the clamping member 212 gradually slides to the outside of the passive slide 2. When the clamping member 212 extends out of the passive slide 2, the clamping member 212 is engaged in the card slot 102c, thereby locking the position of the passive slide 2 and the clamping jaw 3. When the clamping member 212 is engaged in the clamping groove 102c, the locking groove 212b thereon is aligned with the locking strip 216, and under the action of the thrust spring 217, the locking strip 216 is engaged in the locking groove 212b, thereby locking the position of the clamping member 212 to prevent it from being pushed back by the return spring 213. At this point, the position of the clamping jaw 3 is completely defined, ensuring the stability of the clamping of the above-mentioned material.

[0065] When the wedge block 222 is retracted into the inner seat 22 , it completely avoids the wedge portion 11 . Under the power of the drive motor 105 b , the wedge portion 11 will pass through the wedge block 222 and continue to move toward the axis of the lower mold 102 .

[0066] By analogy, the clamping process of the material by the clamping jaws 3 in the remaining clamping units 104 is the same as the above process, except that since the material is of irregular shape, the clamping of the material by the multiple clamping jaws 3 has a front-to-back order. If the material is of regular shape, such as a circle, the process is the same as above, except that the multiple clamping jaws 3 can clamp the material synchronously without a front-to-back order. When the size of the material changes, it does not affect the clamping of the material by the clamping jaws 3, but the moving stroke of the clamping jaws 3 may become larger or smaller to adapt to the size of the material.

[0067] When multiple clamps 3 have finished clamping the material, the position of the material is completely locked. Since the position of each clamp 3 is limited by the clamp 212, the clamp 3 clamps the material rigidly, and even under the interference of external force, the clamp 3 cannot shake, thereby firmly fixing the material at the working position, enhancing the stability of the material when it is fixed, and ensuring the effect of subsequent vulcanization.

[0068] Afterwards, the power motor 101d can control the lifting platform 101e to move downward through the lead screw 101c and the nut 101f, and the lifting platform 101e drives the upper mold 103 to move downward, and the upper mold 103 is pressed down on the material to be vulcanized, and the material is vulcanized by combining the upper mold 103 and the lower mold 102. The vulcanization method of the material is a conventional technology in the art and will not be repeated here.

[0069] When the vulcanization is finished and the clamping jaws 3 need to be reset, the screw 105a can be controlled to reverse by driving the motor 105b. Since the active slide 1 and the wedge 11 have reached the side of the wedge block 222 facing the axis of the lower mold 102, the reverse rotation of the screw 105a will drive the active slide 1 and the wedge 11 to move back, and the wedge 11 will gradually approach the wedge block 222 until it contacts the wedge block 222. At this time, the part that the wedge 11 contacts is the straight surface of the wedge block 222, and it is impossible to press the wedge block 222 upward. Therefore, the wedge-shaped portion 11 can only push the wedge block 222 to slide back, and the wedge block 222 slides the inner seat 22 to the side away from the axis of the lower mold 102 until the inner seat 22 contacts the protrusion 216a, and then the inner seat 22 squeezes the locking strip 216 through the protrusion 216a, so that the locking strip 216 is pulled out from the locking groove 212b, thereby unlocking the clamp 212. After the clamp 212 is unlocked, under the action of the return spring 213, the clamp 212 is disengaged from the clamping groove 102c and retracted into the outer seat 21, thereby unlocking the passive slide 2 and the clamp 3. Then the wedge block 222 pushes the passive slide 2 and the clamp 3 to reset.

[0070] When the passive slide 2 returns to its original position, the wedge strip 102d passes through the multiple through holes in sequence and contacts the wedge block 222. The wedge block 222 moves upward under the action of the wedge strip 102d as it continues to slide, thereby avoiding the wedge portion 11. Then the wedge portion 11 passes over the wedge block 222 and moves to the side of the wedge block 222 away from the axis of the lower mold 102, thereby completing the reset. At this point, all components in the clamping unit 104 have been reset for easy reuse.
