Description

Technical Field

[0001] This utility model relates to the field of rubber product technology, and more specifically, to a rapid prototyping device for rubber production. Background Technology

[0002] Rubber products come in a wide variety of types, but their production processes are basically the same. The basic process of rubber products made from raw rubber, a type of solid rubber, includes six basic steps: plasticizing, mixing, calendering, extrusion, molding, and vulcanization. Among these, the extrusion and molding processes are carried out using extrusion molding equipment.

[0003] Among them, the rapid prototyping equipment for rubber production disclosed in application number CN202420691030.0 is also an increasingly mature technology. Under the action of the linkage mechanism and the stabilizing mechanism, it can shield the rear and left sides of the hot press, avoiding the fact that traditional hot presses do not have additional shielding mechanisms, which can easily lead to other personnel entering the hot pressing range and increase safety risks. Thus, it has the advantage of shielding the hot press.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist: This type of molding equipment requires stopping and waiting during the removal of rubber products, and different molds need to be changed for different specifications of rubber molds, which limits the equipment and affects the production efficiency of rubber molds. Utility Model Content

[0005] The purpose of this invention is to provide a rapid prototyping device for rubber production, so as to solve the problems mentioned in the background art that require stopping the machine to wait when taking out the rubber and that different molds need to be replaced for different specifications of rubber molds.

[0006] This utility model provides a rapid prototyping equipment for rubber production, including a molding device, a quick-release device, and a pick-up device; The forming device includes a frame, a worktable at the bottom of the frame, a cylinder at the top of the frame, a piston end of the cylinder passing through the frame and connected to a coupling, the coupling engaging with a matching convex groove in an L-shaped plate, symmetrical guide blocks on the back of the L-shaped plate, the guide blocks being slidably connected to a guide rail on the surface, the guide rail being installed on the inner side wall of the frame, an upper mold slidably disposed at the bottom of the L-shaped plate, a lower mold disposed at the bottom of the upper mold, and the lower mold being located at the top of the worktable. The quick-release device includes an L-shaped plate with multiple I-shaped grooves at its bottom end, an I-shaped strip slidably disposed inside the I-shaped grooves, a rectangular plate fixedly connected to the bottom end of the I-shaped strip and an upper mold disposed at the bottom end, threaded holes diagonally opened at the bottom end of the L-shaped plate, double-ended studs threadedly connected inside the threaded holes, positioning blocks sleeved on the surface of the double-ended studs, and nuts threadedly connected to the bottom end of the positioning blocks for fixation, locking blocks fixedly connected to both ends of the bottom end of the lower mold, and through holes opened on the surface of the locking blocks, the inside of the through holes being fixedly connected to the top of the workbench by screw threads.

[0007] In this embodiment, the piston end of the cylinder has a self-locking property when it moves to a suitable length. The piston end of the cylinder drives the L-shaped plate to move downward through the coupling. The guide block slides along the guide rail to keep the L-shaped plate on a stable sliding trajectory. When the upper mold and the lower mold are in complete contact, the piston end of the cylinder continues to apply pressure for a set time to ensure that the rubber material is fully formed. After the forming is completed, the cylinder raises the upper mold. The nuts and screws are loosened with tools to release the upper and lower molds. The positioning block and double-headed stud are removed. The upper mold is then slid, and the rectangular plate of the upper mold drives the I-shaped strip to slide out from the I-shaped groove. New upper and lower molds are then installed according to actual needs, and the molds are reinstalled.

[0008] In one embodiment of this utility model, the picking device includes a sliding groove at the bottom of the lower mold, a support rod inside the sliding groove, a movable rod slidably mounted on the surface of the support rod and a compression spring sleeved on the surface, the top of the movable rod being connected to the middle of the I-frame, and rollers rollingly mounted at the top and bottom of both ends of the I-frame, the rollers respectively contacting the bottom of the ejector plate and the interior of the lower mold, and a push rod provided in the center of the front of the I-frame, the push rod penetrating the lower mold and having a cross-shaped handle on the outside.

[0009] In this solution, pushing the handle causes the push rod, the I-frame, and the moving rod to move synchronously. The moving rod slides along the support rod to compress the spring. At the same time, the rollers of the I-frame roll along the ejection plate and the lower mold, pushing the ejection plate upward and causing the rubber mold to be ejected for easy removal. After the mold is completely ejected, the cross-shaped handle is released, and the compression spring pushes the moving rod back to its original position through elastic recovery.

[0010] In one embodiment of this utility model, a return spring is vertically arranged inside the lower mold, the top end of the return spring is connected to the bottom end of the ejection plate, an installation groove is opened inside the lower mold, heating rods are evenly distributed inside the installation groove, and the bottom end of the ejection plate is inclined.

[0011] In this design, a reset spring is used to reset the mold, and a heating rod heats the mold, reducing the adhesion of the rubber material and facilitating demolding.

[0012] In one embodiment of this utility model, the workbench is provided with legs at the bottom and reinforcing ribs in the middle, and each leg is provided with casters with wheel brakes at the bottom.

[0013] In this design, the support legs provide height and stability to the workbench, the reinforcing ribs increase the strength and rigidity of the support legs, the casters facilitate flexible movement of the equipment, and the wheel brakes ensure the safety of the equipment.

[0014] In one embodiment of this utility model, the frame is fitted with a sleeve outside the piston end of the cylinder, the top of the L-shaped plate is symmetrically provided with triangular blocks, and the push rod is fitted with a cylinder through the surface of the lower mold.

[0015] In this design, the friction and wear between components are reduced by using sleeves and cylinders, while triangular blocks increase the structural strength of the L-shaped plate.

[0016] In one embodiment of this utility model, a switch panel is provided on the side of the frame, and a cylinder switch and a heating rod switch are respectively provided on one side of the switch panel. The switch panel is electrically connected to an external power supply.

[0017] In this solution, power is supplied to the electrical equipment through a switch panel, and independent switches provide independent protection for the electrical equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: (1) By pushing the handle, the handle drives the push rod, the I-frame and the moving rod to move synchronously. The moving rod slides along the support rod to compress the spring. At the same time, the rollers of the I-frame roll along the bottom end of the ejection plate and inside the lower mold. The inclined ejection plate at the bottom end helps the rollers of the I-frame to roll more smoothly when sliding. Push the ejection plate upward to push the rubber mold out, making it easy to pick up. After the mold is completely ejected, release the cross-shaped handle. The compression spring will return to its original state through elasticity and push the moving rod back to its original position.

[0019] (2) When it is necessary to change different molds, use tools to loosen the nuts of the double-ended stud and the screws of the locking block, release the fixing of the positioning block to the rectangular plate and the fixing of the lower mold to the worktable, remove the positioning block and rotate the double-ended stud to disassemble it from the inside of the threaded hole, slide the upper mold, and the rectangular plate at the top of the upper mold will drive the I-shaped strip to slide out from the I-shaped groove of the L-shaped plate. Then install the new upper and lower molds according to the actual needs, and reinstall them. The quick-release device simplifies the steps of changing the upper and lower molds, adapts to the needs of different products, can quickly adjust the production line, meet the diverse production requirements, and improve production efficiency.

[0023] Example

[0024] Please see Figure 1-4 This utility model provides a rapid forming equipment for rubber production, including a forming device 100, a quick-release device 200, and a picking device 300. Please refer to the details. Figure 2 and Figure 3The molding device 100 includes a frame 400, a worktable 410 at the bottom of the frame 400, and a cylinder 110 at the top of the frame 400. The piston end of the cylinder 110 passes through the frame 400 and is connected to a coupling 111. The coupling 111 is engaged with the interior of a matching convex groove of an L-shaped plate 112. Symmetrical guide blocks 113 are provided on the back of the L-shaped plate 112. The guide blocks 113 are slidably connected to the surface of a guide rail 114. The guide rail 114 is installed on the inner side wall of the frame 400. An upper mold 115 is slidably provided at the bottom of the L-shaped plate 112. A lower mold 116 is provided at the bottom of the upper mold 115. The lower mold 116 is located at the top of the worktable 410.

[0025] In one specific embodiment, please refer to Figure 2 and Figure 3 When the cylinder 110 is activated, the piston end of the cylinder 110 moves to a suitable length and has a self-locking property. The piston end of the cylinder 110 drives the L-shaped plate 112 to move downward through the coupling 111. The guide block 113 on the back of the L-shaped plate 112 slides along the guide rail 114, so that the L-shaped plate 112 maintains a stable sliding trajectory. The upper mold 115 at the bottom of the L-shaped plate 112 moves downward synchronously and gradually closes with the lower mold 116. When the upper mold 115 and the lower mold 116 are in complete contact, the piston end of the cylinder 110 continues to apply pressure, so that the rubber material is kept under pressure within the lower mold 116 for a set time to ensure that the rubber material is fully formed. After the forming is completed, the cylinder 110 moves in the opposite direction to release the pressure and make the upper mold 115 rise.

[0026] Please see Figure 2 The quick-release device 200 includes an L-shaped plate 112 with multiple I-shaped grooves 210 at its bottom end. I-shaped strips 211 are slidably arranged inside the I-shaped grooves 210. A rectangular plate 212 is fixedly connected to the bottom end of the I-shaped strip 211 and an upper mold 115 is provided at the bottom end. Threaded holes are provided diagonally at the bottom end of the L-shaped plate 112. Double-ended studs 213 are threadedly connected inside the threaded holes. Positioning blocks 214 are fitted on the surface of the double-ended studs 213. Nuts are threadedly connected to the bottom end of the positioning blocks 214 for fixation. Locking blocks 215 are fixedly connected to both ends of the bottom end of the lower mold 116. Through holes are provided on the surface of the locking blocks 215. The inside of the through holes is fixedly connected to the top of the workbench 410 by screw threads.

[0027] In one specific embodiment, please refer to Figure 2By loosening the nuts of the double-ended stud 213 and the screws of the locking block 215 with a tool, the fixing of the positioning block 214 to the rectangular plate 212 and the fixing of the lower mold 116 to the worktable 410 are released. The positioning block 214 is removed and the double-ended stud 213 is rotated to disassemble from the inside of the threaded hole. The upper mold 115 is then slid, and the rectangular plate 212 at the top of the upper mold 115 drives the I-shaped strip 211 to slide out from the I-shaped groove 210 of the L-shaped plate 112. Then, according to the actual needs, new upper and lower molds are installed, and the installation is repeated. The quick-release device 200 simplifies the steps of changing upper and lower molds, adapts to the needs of different products, can quickly adjust the production line, meet diverse production requirements, and improve production efficiency.

[0028] Please see Figure 3 The picking device 300 includes a sliding groove 310 at the bottom of the lower mold 116. A support rod 311 is installed inside the sliding groove 310. A moving rod 312 is slidably installed on the surface of the support rod 311 and a compression spring 313 is sleeved on the surface. The top of the moving rod 312 is connected to the middle of the I-frame 314. Rollers 315 are rolled at the top and bottom of both ends of the I-frame 314. The rollers 315 contact the bottom of the ejection plate 316 and the interior of the lower mold 116 respectively. A push rod 317 is installed in the middle of the front of the I-frame 314. The push rod 317 passes through the lower mold 116 and has a cross-shaped handle on the outside.

[0029] In one specific embodiment, please refer to Figure 3 When the staff pushes the handle, the handle drives the push rod 317, the I-frame 314 and the moving rod 312 to move synchronously. The moving rod 312 slides along the support rod 311 to compress the spring 313. At the same time, the roller 315 of the I-frame 314 rolls along the bottom end of the ejection plate 316 and the inside of the lower mold 116, pushing the ejection plate 316 upward and driving the rubber mold out for easy removal. When the mold is completely ejected, the cross-shaped handle is released, and the compression spring 313 pushes the moving rod 312 back to its original position through its elasticity.

[0030] Please see Figure 3 A return spring 318 is vertically installed inside the lower mold 116. The top end of the return spring 318 is connected to the bottom end of the ejector plate 316. An installation groove 319 is opened inside the lower mold 116. Heating rods 320 are evenly distributed inside the installation groove 319. The bottom end of the ejector plate 316 is inclined.

[0031] In one specific embodiment, please refer to Figure 3 The reset spring 318 serves to reset the mold, and the mounting groove 319 facilitates the installation of the heating rod 320. The heating rod 320 heats the mold, reduces the adhesion of the rubber material, and facilitates demolding. The inclined ejection plate 316 at the bottom helps the roller 315 to roll more smoothly when the I-frame 314 slides.

[0032] Please see Figure 4 The workbench 410 is provided with support legs 411 at the bottom and reinforcing ribs in the middle. Each support leg 411 is provided with casters 412 with wheel brakes at the bottom.

[0033] In one specific embodiment, please refer to Figure 4 The support legs 411 provide height and stability for the workbench 410. The reinforcing ribs increase the strength and rigidity of the support legs 411, preventing deformation and breakage of the support legs 411 under negative pressure. The casters 412 facilitate flexible movement of the equipment, and the wheel brakes ensure the safety of the equipment and prevent arbitrary movement.

[0034] Please see Figure 4 A sleeve is fitted around the piston end of the cylinder 110 in the frame 400. Triangular blocks are symmetrically arranged at the top of the L-shaped plate 112. A cylinder is fitted around the push rod 317 through the surface of the lower mold 116.

[0035] In one specific embodiment, please refer to Figure 4 By using sleeves and cylinders to reduce friction and wear between components, stable operation of moving parts is ensured, and triangular blocks increase the structural strength of L-shaped plate 112.

[0036] Please see Figure 4 A switch panel 413 is provided on the side of the frame 400. A cylinder switch and a heating rod switch are respectively provided on one side of the switch panel 413. The switch panel 413 is electrically connected to an external power supply.

[0037] In one specific embodiment, please refer to Figure 4 The switch panel 413 provides power to the electrical equipment, and the independent switch provides independent protection for the electrical equipment.

The piston end of cylinder 110 drives the L-shaped plate 112 to move downward through coupling 111. The guide block 113 on the back of the L-shaped plate 112 slides along the guide rail 114, keeping the L-shaped plate 112 on a stable sliding trajectory. The upper mold 115 at the bottom of the L-shaped plate 112 moves downward synchronously and gradually closes with the lower mold 116. When the upper mold 115 and the lower mold 116 are in complete contact, the piston end of cylinder 110 continues to apply pressure, keeping the rubber material under pressure within the lower mold 116 for a set time to ensure that the rubber material is fully molded. After molding is completed, cylinder 110 moves in the opposite direction to release the pressure, allowing the upper mold 115 to... As the mold rises, the heating rod 320 heats the mold, reducing the adhesion of the rubber material and facilitating demolding. The inclined ejection plate 316 at the bottom helps the rollers 315 roll more smoothly when the I-frame 314 slides. When the operator pushes the handle, the handle drives the push rod 317, the I-frame 314, and the moving rod 312 to move synchronously. The moving rod 312 slides along the support rod 311 to compress the spring 313. At the same time, the rollers 315 of the I-frame 314 roll along the bottom of the ejection plate 316 and inside the lower mold 116, pushing the ejection plate 316 upward and causing the rubber mold to be ejected for easy removal. After the mold is completely ejected, the cross-shaped handle is released, and the compression spring 313 returns to its original shape through elasticity, pushing the moving rod 312 back to its original position.
