Description

Technical Field

[0001] This invention relates to the field of plastic molding technology, specifically to a molding device and method. Background Technology

[0002] The molding and manufacturing of yoga mats is a multi-step precision process. Its core lies in transforming raw materials into foamed products with specific elasticity, anti-slip properties, and durability. In the foaming molding process, the uniformly mixed hot adhesive is transferred to the foaming production line. The adhesive is placed into the metal mold of a large flat vulcanizing machine. After the mold is closed, the adhesive is precisely heated and pressurized by electric heating plates. The heat triggers the decomposition of the foaming agent, and the adhesive expands within the space defined by the mold, filling the entire mold cavity. At the same time, the continuous pressure ensures that the air bubbles are evenly distributed, the product density is consistent, and the surface is flat. After a set vulcanization time, the material is cured and shaped to form a foamed mat blank with a stable closed-cell or open-cell structure.

[0003] In practice, the operator first accurately weighs the rubber compound and places it into the center area of ​​the lower mold. After the mold closes, the operator sets the heating and pressurization parameters, periodically monitoring the equipment's operation to ensure that the temperature and pressure remain within the set range. After the set vulcanization time is completed, the operator releases the mold pressure and waits for the mold to cool to a safe temperature before carefully removing the foamed pad blank. After cooling and shaping, the removed pad blank is trimmed by a specialist to remove burrs and ensure neat edges. During the process of removing the foamed pad blank from the lower mold of the flat vulcanizing machine, [further details are needed]. The process is mainly manual, and the temperature of the mold and pad after vulcanization and mold opening is usually over 100 degrees Celsius. Each time the pad is removed, the operator needs to complete a series of actions such as approaching the equipment, positioning, grabbing, moving out, and placing it, which takes a long time. Especially when producing large and heavy pads, the cycle time of a single operation will be further extended. After lifting the edge of the pad from the lower mold, the worker needs to completely peel off and transfer the entire pad. During this process, the stretching caused by the pad's own weight, especially for large or highly elastic pads, may cause irreversible dimensional deformation or uneven thickness. Summary of the Invention

[0004] The purpose of this invention is to provide a molding device and method. After the hydraulic flat vulcanizing machine opens the mold, the connecting rod extended-distance tilting drive mechanism is activated through the control panel. The connecting rod extended-distance tilting drive mechanism drives the upper tilting arm to tilt down 90 degrees, so that the dual-axis moving mechanism and the multi-suction cup array adsorption mechanism are suspended on the vulcanized blank. Then, the dual-axis moving mechanism adjusts the spatial position of the multi-suction cup array adsorption mechanism and contacts the upper surface of the blank. The multi-suction cup array adsorption mechanism completes the adsorption of the blank until the blank separates from the lower mold. Finally, the connecting rod extended-distance tilting drive mechanism is reset, so that all parts are withdrawn from the flat vulcanizing machine, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a molding device, comprising a base box, a flat vulcanizing machine mounted on the top of the base box, a sheet metal frame mounted on the back of the base box along its length, and a plurality of lower support arms bolted to the outer wall of the sheet metal frame near the flat vulcanizing machine. The upper ends of the lower support arms are hinged to upper flipping arms. A dual-axis moving mechanism is mounted on the side of the plurality of upper flipping arms away from the base box, and a multi-suction cup array adsorption mechanism is mounted on the drive end of the dual-axis moving mechanism. A linkage flipping drive mechanism for controlling the deflection angle of the upper flipping arms is mounted on the top of the sheet metal frame. The linkage flipping drive mechanism drives the upper flipping arms to fall towards the lower mold of the flat vulcanizing machine until the multi-suction cup array adsorption mechanism is parallel to the horizontal plane. A control panel is mounted on one side of the base box surface, and the output end of the control panel is electrically connected to the input ends of the linkage flipping drive mechanism, the dual-axis moving mechanism, and the multi-suction cup array adsorption mechanism, respectively.

[0006] Preferably, the linkage flipping drive mechanism includes an L-shaped side seat fixed to the left and right sides of the top of the sheet metal frame, a horizontal shaft rotatably mounted between the two L-shaped side seats, and a lower connecting rod fixed to both ends of the horizontal shaft surface. A servo motor is mounted on one outer wall of one of the L-shaped side seats, and the output shaft of the servo motor is fixed to one end of the horizontal shaft.

[0007] Preferably, a connecting platform is bolted to one side of each of the upper tilting arms away from the base box, and upper connecting rods are hinged to both sides of the bottom end of the connecting platform. The lower end of the upper connecting rod is hinged to the upper end of the lower connecting rod through a hinge shaft.

[0008] Preferably, the dual-axis moving mechanism includes a hollow guide frame 1 and a hollow guide frame 2 installed on the outer walls of the two outermost upper flip arms, a first crossbeam plate slidably installed at the lower ends of the hollow guide frame 1 and the hollow guide frame 2, and an electric screw module installed inside the hollow guide frame 1. The electric screw module is used to drive the first crossbeam plate to slide along the length direction of the hollow guide frame 1. Double rail platforms are installed on both sides of the bottom end of the first crossbeam plate. A second crossbeam plate is slidably installed on the back of the two double rail platforms along the vertical direction via rails. The multi-suction cup array adsorption mechanism is installed on the outer wall of the second crossbeam plate on the side close to the flat vulcanizing machine. A cylinder is installed on the top of the double rail platform. The cylinder is used to drive the second crossbeam plate to slide along the length direction of the double rail platform.

[0009] Preferably, the lower end of the piston rod of the cylinder is fixed with a C-shaped head, and a protruding plate extending to the outside of the double track platform is integrally formed on the outer wall of the second crossbeam plate away from the multi-suction cup array adsorption mechanism. The C-shaped head and the protruding plate are connected.

[0010] Preferably, the top of the second crossbeam plate is provided with a rectangular notch, and the length of the rectangular notch is greater than the straight-line distance between the two outermost upward flipping arms.

[0011] Preferably, the multi-suction cup array adsorption mechanism includes two connecting rods fixed to both sides of the back of the second crossbeam plate, a double-hole rod seat fixed to the ends of the two connecting rods on the same side away from the second crossbeam plate, and a square beam installed at the top and bottom of the double-hole rod seat. Several forked arms are installed at equal intervals on the outer wall of the side of the square beam away from the second crossbeam plate, and vacuum suction cups are installed on the side of the forked arms away from the square beam.

[0012] Preferably, one end of the forked arm is provided with a spiral sleeve, and a locking handle is installed on one outer wall of the spiral sleeve. The forked arm is fitted with the spiral sleeve and the square beam and is fastened to the square beam by the locking handle.

[0013] Preferably, four lower support arms are provided, and both the lower support arms and the upper flipping arms are made of aluminum alloy.

[0014] The present invention also provides a molding method using the above-described equipment, comprising the following steps:

[0015] S101: The mixed quantitative rubber compound is placed in the center area of ​​the mold of the preheated flat vulcanizing machine. The operator starts the mold closing and automatic vulcanization program through the control panel. Under the preset temperature and pressure, the rubber compound completes foaming, expansion and vulcanization in the closed mold cavity.

[0016] S102: After vulcanization, the flat vulcanizing machine opens the mold. The material handling sequence is started through the control panel. The connecting rod flipping drive mechanism drives the upper flipping arm to rotate smoothly and accurately forward and downward about 90 degrees and fall down. After the multi-suction cup array adsorption mechanism is suspended in place, the operator commands the dual-axis moving mechanism to start fine adjustment through the control panel to drive the multi-suction cup array adsorption mechanism to perform precise positioning in the horizontal and vertical directions until the entire multi-suction cup array adsorption mechanism is aligned and coincident with the upper surface of the vulcanized and formed pad in the lower mold. Then the multi-suction cup array adsorption mechanism descends, so that all the suction cups are in uniform contact with the surface of the pad and start negative pressure adsorption. Under the action of uniform adsorption force, the entire pad is lifted smoothly and synchronously from the lower mold.

[0017] S103: After adsorption and lifting are completed, the operator once again uses the control panel to command the linkage flipping drive mechanism to reset, so that the upper flipping arm, the dual-axis moving mechanism, and the multi-suction cup array adsorption mechanism, carrying the firmly adsorbed pad blank, slowly swing upwards by 90 degrees, returning to the initial state of the vertical position, thereby allowing all moving parts to be completely removed from the working area of ​​the flat vulcanizing machine.

[0018] S104: The multi-suction cup array adsorption mechanism releases the vacuum, and the operator releases the complete pad onto the designated conveyor belt or cooling station for subsequent processing.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The molding equipment and method are equipped with a structure that includes a linkage-extended tilting drive mechanism, a lower support arm, an upper tilting arm, a dual-axis moving mechanism, and a multi-suction cup array adsorption mechanism, which work together. The linkage-extended tilting drive mechanism is activated via the control panel, causing the upper tilting arm to tilt 90 degrees, suspending the dual-axis moving mechanism and the multi-suction cup array adsorption mechanism on the vulcanized blank. The dual-axis moving mechanism then adjusts the spatial position of the multi-suction cup array adsorption mechanism to contact the upper surface of the blank, allowing the multi-suction cup array adsorption mechanism to adsorb the blank until it separates from the lower mold. Finally, the linkage-extended tilting drive mechanism resets, allowing all parts to exit the flat vulcanizing machine, eliminating the inconvenience of manual operation. By avoiding delays in action transitions, individual physical differences, and necessary rest intervals, the flat vulcanizing machine can enter the next production cycle with the shortest possible waiting time after completing vulcanization and mold opening. This shortens the production cycle time per unit and improves the molding efficiency of yoga mat blanks. Furthermore, the multi-suction cup array adsorption mechanism utilizes pneumatic uniform adsorption to act synchronously and stably on the entire upper surface of the mat blank, maximizing the force-bearing area and uniformizing the force state. This avoids the hidden damage to the mat blank caused by local lifting, finger pressing, or uneven force in traditional manual operation, such as micro-tears in the internal cell structure, local density changes, or irreversible tensile deformation. In addition, the precise spatial positioning provided by the dual-axis moving mechanism ensures that each molded mat blank is gently removed in almost the same way, guaranteeing product consistency.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1, by Figures 1 to 5The present invention includes a base box 1, a flat vulcanizing machine 2 installed at the top of the base box 1, a sheet metal frame 4 installed along the length of the back of the base box 1, and a plurality of lower support arms 5 bolted to the outer wall of the sheet metal frame 4 near the flat vulcanizing machine 2. The upper end of the lower support arms 5 is hinged to an upper flipping arm 6. A dual-axis moving mechanism 8 is installed on the side of the plurality of upper flipping arms 6 away from the base box 1, and a multi-suction cup array adsorption mechanism 9 is installed at the drive end of the dual-axis moving mechanism 8. A linkage flipping drive mechanism 7 for controlling the deflection angle of the upper flipping arms 6 is installed at the top of the sheet metal frame 4. The linkage flipping drive mechanism 7 drives the upper flipping arms 6 to fall towards the lower mold of the flat vulcanizing machine 2 until the multi-suction cup array adsorption mechanism 9 is parallel to the horizontal plane. A control panel 3 is installed on one side of the surface of the base box 1. The output end of the control panel 3 is electrically connected to the input end of the linkage flipping drive mechanism 7, the dual-axis moving mechanism 8, and the multi-suction cup array adsorption mechanism 9, respectively.

[0034] A molding method according to this embodiment, using the above-described equipment, includes the following steps:

[0035] S101: The mixed quantitative rubber compound is placed in the center area of ​​the mold of the preheated flat vulcanizing machine 2. The operator starts the mold closing and automatic vulcanization program through the control panel 3. Under the preset temperature and pressure, the rubber compound completes foaming, expansion and vulcanization in the closed mold cavity.

[0036] S102: After vulcanization, the flat vulcanizing machine 2 opens the mold and starts the material feeding sequence through the control panel 3. The connecting rod flipping drive mechanism 7 drives the upper flipping arm 6 to rotate forward and downward about 90 degrees smoothly and accurately from the vertical storage position. After the multi-suction cup array adsorption mechanism 9 is suspended in place, the operator commands the dual-axis moving mechanism 8 through the control panel 3 to start fine adjustment, so as to drive the multi-suction cup array adsorption mechanism 9 to perform precise positioning in the horizontal and vertical directions until the entire multi-suction cup array adsorption mechanism 9 is aligned and coincident with the upper surface of the vulcanized and formed pad blank in the lower mold. Then the multi-suction cup array adsorption mechanism 9 descends, so that all the suction cups are in uniform contact with the surface of the pad blank and start negative pressure adsorption. Under the action of uniform adsorption force, the entire pad blank is lifted smoothly and synchronously from the lower mold.

[0037] S103: After adsorption and lifting are completed, the operator once again uses the control panel 3 to command the linkage flipping drive mechanism 7 to reset, so that the upper flipping arm 6, the dual-axis moving mechanism 8, and the multi-suction cup array adsorption mechanism 9, carrying the firmly adsorbed pad blank, slowly swing upward 90 degrees to return to the initial state of the vertical position, thereby making all moving parts completely withdraw from the working area of ​​the flat vulcanizing machine 2.

[0038] S104: The multi-suction cup array adsorption mechanism 9 releases the vacuum, and the staff releases the complete pad blank onto the designated conveyor belt or cooling station for subsequent processing.

[0039] Example 2, based on Example 1, is... Figure 6 , Figure 7 , Figure 8 and Figure 9 The linkage flipping drive mechanism 7 includes an L-shaped side seat 701 fixedly connected to the left and right sides of the top of the sheet metal frame 4, a horizontal shaft 703 rotatably mounted between the two L-shaped side seats 701, and a lower connecting rod 705 fixedly connected to both ends of the surface of the horizontal shaft 703. A servo motor 702 is mounted on one outer wall of one of the L-shaped side seats 701, and the output shaft of the servo motor 702 is fixedly connected to one end of the horizontal shaft 703.

[0040] A connecting platform 704 is bolted to one side of several upper tilting arms 6 away from the bottom box 1, and upper connecting rods 706 are hinged to both sides of the bottom end of the connecting platform 704. The lower end of the upper connecting rod 706 is hinged to the upper end of the lower connecting rod 705 through a hinge shaft.

[0041] When the linkage flipping drive mechanism 7 starts to operate, the servo motor 702 works under the control of the control panel 3. The servo motor 702 drives the horizontal shaft 703 to rotate. During this process, the horizontal shaft 703 will drive the fixed lower linkage 705 to deflect. Since the upper end of the lower linkage 705 and the lower end of the upper linkage 706 are hinged, the lower linkage 705 will push the connecting table 704 and the upper flipping arm 6 to flip along the upper end of the lower support arm 5 as the axis during the deflection. This continues until the upper flipping arm 6, the dual-axis moving mechanism 8, and the multi-suction cup array adsorption mechanism 9 fall 90 degrees toward the flat vulcanizing machine 2. During this process, the included angle between the lower linkage 705 and the upper linkage 706 gradually increases.

[0042] The linkage flipping drive mechanism 7, through the action of the linkage, transforms a small input displacement into a large working stroke and reliable output force of the upper flipping arm 6, accurately sending the dual-axis moving mechanism 8 and the multi-suction cup array adsorption mechanism 9 into the narrow working area above the mold, and completely withdrawing after completion, making safe space for the mold closing of the vulcanizing machine in the next cycle.

[0043] Example 3, based on Example 2, by Figure 10 , Figure 11 As shown, there are four lower support arms 5, and both the lower support arms 5 and the upper flipping arms 6 are made of aluminum alloy. The lower support arms 5 and the upper flipping arms 6 constitute the mechanical skeleton and load-bearing body of the material picking part. The lower support arms 5 provide a stable mounting base and rotation fulcrum to ensure the rigidity and stability of the entire flipping movement, while the upper flipping arms 6, as the execution load-bearing component, have sufficient structural strength to suspend the dual-axis moving mechanism 8 and the multi-suction cup array adsorption mechanism 9.

[0044] The dual-axis moving mechanism 8 includes a hollow guide frame 1 801 and a hollow guide frame 2 802 mounted on the outer walls of the two outermost upper flip arms 6, a first crossbeam plate 803 slidably mounted at the lower ends of the hollow guide frame 1 801 and the hollow guide frame 2 802, and an electric screw module 804 installed inside the hollow guide frame 1 801. The electric screw module 804 is used to drive the first crossbeam plate 803 to slide along the length direction of the hollow guide frame 1 801. Double rail platforms 805 are installed on both sides of the bottom end of the first crossbeam plate 803. A second crossbeam plate 806 is slidably mounted on the back of the two double rail platforms 805 along the vertical direction via rails. A multi-suction cup array adsorption mechanism 9 is installed on the outer wall of the second crossbeam plate 806 near the flat vulcanizing machine 2. A cylinder 807 is installed on the top of the double rail platform 805. The cylinder 807 is used to drive the second crossbeam plate 806 to slide along the length direction of the double rail platform 805.

[0045] The piston rod of cylinder 807 is fixed with a C-shaped head 8071 at the lower end. The outer wall of the second crossbeam plate 806 away from the multi-suction cup array adsorption mechanism 9 is integrally formed with a protruding plate 8061 that extends to the outside of the double track platform 805. The C-shaped head 8071 and the protruding plate 8061 are connected. The bottom end of the piston rod of cylinder 807 drives the second crossbeam plate 806 and the multi-suction cup array adsorption mechanism 9 to move through the C-shaped head 8071 and the protruding plate 8061. The top of the second crossbeam plate 806 is provided with a rectangular notch. The length of the rectangular notch is greater than the straight distance between the two outermost upper flip arms 6.

[0046] When the connecting rod flipping drive mechanism 7 forces the dual-axis moving mechanism 8 and the multi-suction cup array adsorption mechanism 9 to tilt down ninety degrees, the cylinder 807 drives the second crossbeam plate 806 and the multi-suction cup array adsorption mechanism 9 to move horizontally, so as to adjust the relative position relationship between the multi-suction cup array adsorption mechanism 9 and the pad blank, and also facilitate the avoidance action in the subsequent material removal stage.

[0047] The electric lead screw module 804 is used to drive the first crossbeam plate 803, the double track platform 805, the cylinder 807, the second crossbeam plate 806 and the multi-suction cup array adsorption mechanism 9 to descend or rise, so as to enable the multi-suction cup array adsorption mechanism 9 to contact the pad blank and achieve stable and complete adsorption.

[0048] The multi-suction cup array adsorption mechanism 9 includes two connecting rods 901 fixed to both sides of the back of the second crossbeam plate 806, a double-hole rod seat 902 fixed to the ends of the two connecting rods 901 on the same side away from the second crossbeam plate 806, and a square beam 903 installed at the top and bottom of the double-hole rod seat 902. Several forked arms 904 are installed at equal intervals on the outer wall of the side of the square beam 903 away from the second crossbeam plate 806, and a vacuum suction cup 905 is installed on the side of the forked arm 904 away from the square beam 903. A U-shaped sleeve is provided at one end of the forked arm 904, and a locking handle is installed on the outer wall of one side of the U-shaped sleeve. The forked arm 904 is fitted with the U-shaped sleeve and the square beam 903 and is fastened to the square beam 903 by the locking handle.

[0049] When the electric screw module 804 controls the positions of the first crossbeam plate 803, the second crossbeam plate 806, and the multi-suction cup array adsorption mechanism 9, the double-hole rod seat 902 maintains synchronous movement with the second crossbeam plate 806 through the connecting rod 901. All vacuum suction cups 905 are connected through a common vacuum air path. When the external vacuum generator is activated, each vacuum suction cup 905 generates negative pressure synchronously to adsorb the entire surface area of ​​the pad. The evenly distributed force allows the pad to separate smoothly from the mold without being bent, stretched, or subject to local stress concentration.

A method for molding, using the equipment as described in any one of claims 1-9, characterized in that: Includes the following steps: S101: The mixed quantitative rubber compound is placed in the center area of ​​the mold of the preheated flat vulcanizing machine (2). The operator starts the mold closing and automatic vulcanization program through the control panel (3). Under the preset temperature and pressure, the rubber compound completes foaming, expansion and vulcanization in the closed mold cavity. S102: After vulcanization is completed, the flat vulcanizing machine (2) opens the mold and starts the material taking sequence through the control panel (3). The connecting rod flipping drive mechanism (7) drives the upper flipping arm (6) to rotate 90 degrees forward and downward smoothly and accurately from the vertical storage position. When the multi-suction cup array adsorption mechanism (9) is suspended in place, the operator instructs the dual-axis moving mechanism (8) through the control panel (3) to start fine adjustment to drive the multi-suction cup array adsorption mechanism (9) to perform precise positioning in the horizontal and vertical directions until the multi-suction cup array adsorption mechanism (9) is aligned and overlapped with the upper surface of the vulcanized pad blank in the lower mold. Then the multi-suction cup array adsorption mechanism (9) descends, so that all the suction cups are in uniform contact with the surface of the pad blank and start negative pressure adsorption. Under the action of uniform adsorption force, the entire pad blank is lifted smoothly and synchronously from the lower mold. S103: After adsorption and lifting are completed, the operator once again uses the control panel (3) to command the linkage flipping drive mechanism (7) to reset, so that the upper flipping arm (6), the dual-axis moving mechanism (8), and the multi-suction cup array adsorption mechanism (9) carry the firmly adsorbed pad blank and slowly swing it back ninety degrees to return to the initial state of the vertical position, so that all moving parts are completely removed from the working area of ​​the flat vulcanizing machine (2). S104: The multi-suction cup array adsorption mechanism (9) releases the vacuum, and the staff releases the complete pad blank to the designated conveyor belt or cooling station for subsequent processing.
