[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] In the description of this utility model, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0051] This utility model provides a slush molding device that requires little or no manual intervention, significantly reducing reliance on operators and labor costs, and minimizing errors that may be introduced by human operation.

[0052] The following is combined Figures 1-9 The technical solution provided by this utility model will be described in more detail.

[0053] See Figures 1-9 As shown, the slush molding device provided by this utility model includes a frame, a capping assembly 1, a turntable 2, a feeding assembly 3, an oven 4, and a turntable 5 located on the frame. The turntable 5 supports a positioning mold plate assembly 6, which has a mold body and a mold cover 60. The turntable 5 is rotatably connected to the turntable 2, and all turntables 5 are arranged around the center of the turntable 2. The capping assembly 1 is movably arranged in the horizontal direction and is used to grab or close the mold cover 60. The frame is provided with at least a material feeding station 101, a heating waiting station 102, a cooling station 103, and a buffer station 104. The material feeding station 101 is arranged facing the feeding assembly 3, which is used to add raw materials to the mold body located on the material feeding station 101. The heating waiting station 102 is arranged facing the oven 4. The turntable 2 is rotatable about its own axis, thereby rotating the mold plate assembly 6 on the turntable 5 to different stations.

[0054] In this embodiment, the horizontal movement can be achieved through a combination of a motor, gears, and racks, or through a commonly used linear servo module, such as... Figure 1 The driving structure for horizontal motion is shown in the figure. As a conventional method, it will not be described in detail here.

[0055] The frame, serving as the supporting foundation for the entire device, can be welded from structural steel or steel plates to ensure sufficient strength and rigidity. The turntable 2 can rotate intermittently under the drive of its central axis. In one embodiment of this application, see... Figure 1 and Figure 2 As shown, four turntables 5 (or supports) are specifically set on the turntable 2, with an included angle of 90 degrees between them. Each turntable 5 (or support) is used to support and position a mold plate group 6.

[0056] To achieve a continuous automated production process, multiple functional stations are divided at corresponding positions on the frame along the rotation path of the turntable 2. Specifically, these stations include the aforementioned material feeding station 101, heating station 102, cooling station 103, and buffer station 104. At the feeding station, a sealing assembly 1 for automatic mold opening and closing and a feeding assembly 3 for automatic material addition are provided. At the heating station, an oven 4 is provided as a heating unit. At the cooling station 103, a fan or other cooling equipment can be installed to cool the heated mold.

[0057] When turntable 2 rotates 90 degrees, the four turntables 5 and the mold trays 6 they carry can be synchronously and sequentially transferred to the next workstation. In this way, different mold trays 6 can perform corresponding processes in parallel at different workstations, thereby greatly improving equipment utilization and production efficiency.

[0058] As an alternative implementation, see [link to implementation details]. Figure 2 As shown, the mold assembly 6 also includes a cover fixing plate 61, a mold fixing plate 62, and a gripping rod 63. All mold covers 60 are fixed to the cover fixing plate 61, all mold bodies are fixed to the mold fixing plate 62, and the gripping rod 63 is fixedly connected to the cover fixing plate 61. The mold fixing plate 62 has a rectangular through hole 621, and the bottom end of the gripping rod 63 has a hook 632. The cover assembly 1 and the cover fixing plate 61 have a locked state and a disengaged state. When locked, the cover assembly 1 is positioned and connected to the gripping rod 63, thereby causing the gripping rod 63 to rotate around its axis. When the hook 632 rotates to the diagonal position of the rectangular through hole 621, the cover fixing plate 61 can disengage from the mold fixing plate 62.

[0059] Multiple mold covers 60 are firmly fixed to the lower surface of the cover fixing plate 61 by bolts or other means. The cover fixing plate 61 and all the mold covers 60 form an integral cover unit.

[0060] To enable automatic gripping, lifting, and rotation of the cover unit, a gripping rod 63 is fixedly connected to the cover fixing plate 61. See also Figures 4-6 As shown, the gripper 63 can be a solid or hollow metal rod with a specific geometry or interface at its top to facilitate reliable connection with the cap assembly 1 described later. At the bottom end of the gripper 63, i.e., the portion passing through and extending below the cap fixing plate 61, a hook 632 is provided. In this embodiment, the hook 632 is T-shaped or elongated.

[0061] Corresponding to hook 632, see Figure 5 A rectangular through hole 621 is provided at the center of the mold fixing plate 62. The long side of the rectangular through hole 621 is slightly longer than the long side of the hook 632, and the short side is slightly longer than the width of the hook 632 but shorter than the long side of the hook 632. This dimensional fit forms the basis for realizing rotational locking.

[0062] See Figure 5 As shown, Figure 5 When the middle hook 632 is rotated to the diagonal position of the rectangular through hole 621, the hook 632 can be dislodged from the rectangular through hole 621, and the cover assembly 1 can be removed by the grab rod 63 to drive the cover fixing plate 61 to be removed.

[0063] The capping assembly 1 is the core mechanism for performing the automatic opening and closing of the mold cap. As an optional implementation, see [link to implementation details]. Figures 4-6As shown, the capping assembly 1 in this embodiment includes a mounting frame 11, a rotation drive device 12, a lifting drive device 13, a drive disk 14, and a rod assembly 15. The rotation drive device 12 and the lifting drive device 13 are both fixed to the mounting frame 11. The lifting drive device 13 is fixedly connected to the drive disk 14 and is used to drive the drive disk 14 to rise and fall. The rotation drive device 12 is drively connected to the rod assembly 15 and is used to drive the rod assembly 15 to rotate on the drive disk 14. The rod assembly 15 can be positioned and connected to the gripper 63 and drive the gripper 63 to rotate. The gripper 63 can rotate to a position where it is disengaged from the mold fixing plate 62, and the gripper 63 can rotate to a position where it is locked or disengaged from the drive disk 14. When the gripper 63 is locked to the drive disk 14, the gripper 63 is disengaged from the mold fixing plate 62.

[0064] The lifting drive device 13 can be a ball screw mechanism or cylinder driven by a servo motor, which can drive the end effector, i.e., the lever assembly 15, to perform precise vertical lifting and lowering movements (Z-axis movement). The rotation drive device 12 can be a stepper motor or a servo motor, which drives the lever assembly 14 to rotate around its own central axis via gear or synchronous belt transmission. The end of the lever assembly 15 has a clamping or engaging structure that matches the top of the gripper 63, such as an internal hexagonal or internal spline sleeve or, in this embodiment, a positioning block 153 with a slot 1531. When the lever assembly 15 descends, it can automatically and accurately engage and lock the gripper 63, thereby transmitting its own lifting and rotational movements to the gripper 63.

[0065] As an alternative implementation, see [link to implementation details]. Figures 5-6 As shown, the disc rod assembly 15 of this embodiment includes a central disc 151, a swing rod 152, and a positioning block 153. The rotation drive device 12 is driven to connect with the central disc 151 and is used to drive the central disc 151 to rotate around its own axis. One end of the swing rod 152 is rotatably connected to the central disc 151 and is offset from the center of the central disc 151. The other end is rotatably connected to the positioning block 153. The top of the gripping rod 63 is provided with an insertion part 631, and the bottom of the positioning block 153 is provided with a slot 1531. The positioning block 153 can descend to the position where the insertion part 631 is inserted into the slot 1531, thereby realizing that the gripping rod 63 rotates with the positioning block 153 in the horizontal plane.

[0066] See Figure 6 As shown, the central disk 151 is connected to the output end of the rotation drive device 12 via a vertical shaft. The rotation drive device 12 drives the central disk 151 to rotate, thereby causing the swing rod 152 to swing, thus realizing the swing of the positioning block 153. (See also...) Figure 6As shown, since the slot 1531 on the positioning block 153 is positioned with the insertion part 631 on the top of the gripper 63 (and can rotate synchronously in the horizontal direction), when the positioning block 153 swings, the gripper 63 rotates accordingly. Therefore, the rotating rod can be disengaged from the rectangular through hole 621 on the mold fixing plate 62, thereby unlocking the cover fixing plate 61 and the mold fixing plate 62.

[0067] As an alternative implementation, see [link to implementation details]. Figures 4-6 As shown, a locking block 633 is fixedly installed on the top of the gripper 63, and a slot 141 is fixedly installed on the bottom of the drive disc 14. The locking block 633 can rotate to a position where it engages with the slot 141 or disengages from the slot 141 under the drive of the disc rod assembly 15. When the locking block 633 engages with the slot 141, the hook 632 disengages from the rectangular through hole 621.

[0068] When the capping assembly 1 needs to be capped, the drive device 12 rotates in the opposite direction, the drive disk 14 descends, and the gripping rod 63 is positioned and locked with the mold fixing plate 62. At this time, the slot 141 on the drive disk 14 can disengage from the locking block 633 on the top of the gripping rod 63. At this time, the drive disk 14 can disengage from the cap fixing plate 61, and the capping assembly 1 moves horizontally, waiting for the next cap removal or capping.

[0069] As an alternative implementation, see [link to implementation details]. Figure 4 As shown, the capping assembly 1 also includes a telescopic drive device 16 and a push rod 17, wherein: the telescopic drive device 16 is fixed on the mounting bracket 11, the push rod 17 is fixed to the telescopic end of the telescopic drive device 16, the drive disc 14 and the cap fixing plate 61 are provided with through holes for the push rod 17 to pass through, and the bottom end of the push rod 17 is used to abut against the upper surface of the mold fixing plate 62.

[0070] The telescopic drive device 16 can be a telescopic cylinder, etc. When the capping assembly 1 lifts the cap fixing plate 61, the bottom end of the push rod 17 is used to abut against the upper surface of the mold fixing plate 62 to apply downward pressure to the mold fixing plate 62, preventing the mold fixing plate 62 from moving upward, so that the action of removing the cap fixing plate 61 can be completed smoothly.

[0071] As an alternative implementation, see [link to implementation details]. Figure 7 As shown, the slush molding device also includes a material picking assembly 7, which includes a movable frame 71, a lifting drive device 72, and a suction cup assembly 73. The movable frame 71 is movably mounted on the frame in the horizontal direction. The lifting drive device 72 is fixed on the movable frame 71 and drives the suction cup assembly 73 to lift and lower, thereby adsorbing and fixing the product.

[0072] The lifting drive device 72 can be a motor, and the lifting drive device 72 is driven by, for example... Figure 7The belt and pulley structure shown enables the lifting and lowering of the moving frame 71. The suction cup assembly 73 includes one or more vacuum suction cups. Its working process is as follows: After a mold platen 6 that has completed the heating and cooling process is rotated by the turntable 2 to pick up and feed material at the material feeding station 101, the capping assembly 1 performs the capping action again. Subsequently, the material picking assembly 7 moves above the open mold, and the end suction cup assembly 73 descends and contacts the cooled and solidified slush product inside the mold body. The vacuum system is activated to generate suction, adsorbing and removing the product from the mold. Afterward, the robotic arm transfers the product to the adjacent conveyor belt or collection box, completing one automatic material picking cycle.

[0073] As an alternative implementation, see [link to implementation details]. Figure 1 and Figure 8 As shown, the slush molding device also includes a gripper assembly 8, which includes a movable base 81, an extension arm 82, a fixed base plate 83, and a movable clamping plate 84. The movable base 81 is movably mounted on the frame in the horizontal direction. The upper end of the extension arm 82 is fixed to the movable base 81, and the lower end of the extension arm 82 is fixedly connected to the fixed base plate 83. The movable clamping plate 84 is rotatably connected to the fixed base plate 83 and can close or open with the fixed base plate 83 under the drive of a drive cylinder (not shown in the figure). When the movable clamping plate 84 is closed with the fixed base plate 83, it can grip the mold plate assembly 6 and transfer it between the heating station 102 and the oven 4.

[0074] When the mold tray assembly 6 reaches the heating station, it does not directly enter the oven 4, but stays at the entrance of the oven 4, i.e., the heating waiting station 102. At this time, the gripper assembly 8 holds the mold fixing plate 62 of the entire mold tray assembly 6 or a specially designed lifting structure, lifts it from the turntable 2, and then horizontally sends it into the material rack inside the oven 4 for heating. After heating is completed, the gripper assembly 8 re-enters the oven 4, grabs the mold tray assembly 6, and accurately places it back into the empty or original position on the turntable 2. The above structure allows the turntable 2 itself not to bear the high temperature inside the oven 4, thereby extending its service life and making the design of the oven 4 more flexible.

[0075] As an alternative implementation, see [link to implementation details]. Figure 1 and Figure 9 As shown, the feeding assembly 3 is movable on the frame in both the horizontal and vertical directions. The feeding assembly 3 includes two or more discharge pipes 31 for injecting raw materials of different colors into the mold body.

[0076] The feeding assembly 3 includes at least two (e.g., three or four) independently controllable discharge pipes 31. Each discharge pipe 31 is connected to a storage tank containing different colored slush resin raw materials via an independent pipeline and valve. During the feeding step, the opening / closing timing and discharge volume of each discharge pipe 31 can be controlled according to a preset product formula. For example, the first color raw material can be injected into the mold first, followed by the second color raw material, to create a layered or mixed effect, thereby producing multi-colored slush resin products with a more colorful appearance.

[0077] As an alternative implementation, see [link to implementation details]. Figures 1-3 As shown, the slush molding device also includes a first rotary drive device and a second rotary drive device 92, wherein: an external gear ring 93 is fixedly installed at the center hole of the turntable 2, and the axis of the external gear ring 93 is collinear with the central axis of the turntable 2. The first rotary drive device is driven to connect with the external gear ring 93, thereby driving the turntable 2 to rotate; the second rotary drive device 92 is fixed on the turntable 2 and driven to connect with the corresponding turntable 5, thereby causing the turntable 5 to rotate on the turntable 2 with its own axis as the axis; when the turntable 5 rotates intermittently, the feeding component 3 can feed material into the mold body in different areas on the mold fixing plate 62.

[0078] The first rotary drive device can be a high-power servo motor with a reducer and encoder to ensure that the turntable 2 can stop precisely at each preset work position angle. A drive gear 91 is fixed to the output end of the first rotary drive device, such as... Figure 3 As shown, the drive gear 91 meshes with the gear ring fixed in the center of the turntable 2, thereby driving the turntable 2 to rotate around its own axis. The purpose of this structure is to enable the mold plate group 6 to rotate to different work positions.

[0079] The second rotary drive device 92 can be a small servo motor, stepper motor, or hydraulic motor. The turntable 5 is rotatably connected to the turntable 2, for example, through a thrust ball bearing or angular contact bearing, so that the upper part of the turntable 5 carrying the mold disk assembly 6 can rotate relative to it and fixed on the turntable 2. The purpose of this structure is to realize the rotation of each mold disk assembly 6 on the turntable 2. 20-40 molds can be set on the mold disk assembly 6 at the same time. These molds are distributed in a matrix on the mold fixing plate 62. After the cover is removed, the mold disk assembly 6 rotates 90 degrees on the turntable 2 each time. The feeding component 3 can feed materials to the molds in different areas on the mold fixing plate 62, improving the feeding efficiency and realizing the mass production of products.

[0080] The following is combined with Figures 1-9 The method for automating the opening and closing of the lid and the feeding process in this embodiment is described in detail. The method includes the following steps:

[0081] First, turntable 2 rotates, and mold assembly 6 is transferred to the feeding station. A mold assembly 6 in a closed and locked state, ready for feeding, is precisely transported and positioned at the feeding station, directly below the capping assembly 1. Then, at the feeding station, the mold cover 60 is unlocked via the capping assembly 1. The disc rod assembly 15 of the capping assembly 1 descends, and its positioning block 153 reliably connects to the insertion part 631 at the top of the gripper rod 63. At this time, the hook 632 is locked, its long side intersecting the long side of the rectangular through hole 621 at a 90-degree angle, and the locking block 633 engages with the slot 141 at the bottom of the mold fixing plate 62. Next, the drive device 12 is activated, driving the disc rod assembly 14 and rotating the gripper rod 63 by 90 degrees. After rotation, the long side of the hook 632 aligns with the long side of the rectangular through hole 621, as shown below. Figure 5 As shown. At this point, the hook 632 can pass smoothly through the rectangular through hole 621, and the locking state of the cover fixing plate 61 is released.

[0082] After the unlocking action is completed, the mold cover 60 is opened via the sealing assembly 1. The lifting drive device 13 is activated, and the drive disc 14 rod assembly is lifted vertically upward. Since the disc rod assembly 15 is connected to the gripping rod 63, the gripping rod 63 drives the fixed cover plate 61 and all the mold covers 60 on it to rise synchronously, detaching from the mold fixing plate 62, thereby realizing the batch automatic opening of all molds. After the mold cover 60 is lifted and held in the open position, raw materials are added to the opened mold body via the feeding assembly 3. The feeding assembly 3 starts working, precisely injecting a predetermined amount of liquid sizing material (such as polyvinyl chloride paste resin) into each mold body.

[0083] After material feeding is completed, the mold cover 60 is closed by the sealing assembly 1. The lifting drive device 13 moves in the reverse direction, and the drive disc 14 rod assembly descends smoothly, placing the cover fixing plate 61 and the mold cover 60 back onto the mold fixing plate 62, ensuring that the mold cover 60 is accurately aligned with the mold body and closed. After the mold cover 60 is closed, the sealing assembly 1 locks the mold cover 60. The rotating drive device 12 rotates 90 degrees in the reverse direction, and the hook 632 once again engages the mold fixing plate 62, completing the automatic locking of the mold. After the locking action is completed, the disc rod assembly 15 disengages from the grab rod 63 and resets.

[0084] Turntable 2 rotates, transferring mold assembly 6 to the heating station 102, where oven 4 heats the mold assembly 6. Inside oven 4, the liquid material inside the mold gels and melts, forming a plastic layer of the required thickness on the inner wall of the mold.

[0085] After heating, the mold plate assembly 6 is picked up by the gripper and placed back into the heating waiting station 102. The turntable 2 rotates, and the mold plate assembly 6 moves to the cooling station 103 for cooling. After cooling, the turntable 2 drives the mold plate assembly 6 to rotate to the material feeding station 101. The capping component 1 removes the cap, and the material feeding component 7 transfers the finished product.
