Description

Technical Field

[0001] This utility model relates to the field of rotational molding mold technology for seat accessory production, specifically a rotational molding mold for hot rotational molding lining processing. Background Technology

[0002] Rotational molding is a processing method for plastic products. During the molding process, the mold is connected to the drive equipment via guide rails and is constantly rotating. It has advantages such as high efficiency, low cost, and fast production speed, and is therefore widely used in production. Some seat accessories and linings are also processed by rotational molding molds. Rotational molding molds are usually divided into upper molds and lower molds, which are fixed by bolts. Disassembly or installation is relatively troublesome, which wastes a lot of workers' time and reduces the efficiency of rotational molding molds.

[0003] To address the aforementioned shortcomings, the prior art (Chinese patent with publication number CN219294522U and publication date of 2023-07-04) provides a rotational molding mold that is easy to disassemble and assemble. By employing a disassembly and assembly device, the mold can be locked and unlocked by turning the handle during the disassembly and assembly process. This saves a significant amount of time in the rotational molding production process by removing and assembling bolts, thereby achieving the effect of saving time and improving the production efficiency of anaerobic reactor molds.

[0004] The above solution uses equally spaced handles and corresponding connectors to connect and fix the upper and lower molds of the rotational molding die. However, during operation, each handle needs to be turned to lock, which takes a long time and is not convenient for quick connection, thus affecting the production efficiency of hot rotational molding lining. Utility Model Content

[0005] The purpose of this utility model is to provide a rotational molding mold for hot rotational molding lining, so as to solve the problem mentioned in the background art that the existing rotational molding mold is not convenient to disassemble and assemble during use, thus affecting the production efficiency of hot rotational molding lining.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotational molding mold for hot rotational molding lining, comprising an upper mold, a lower mold connected to the lower part of the upper mold, a first connecting edge integrally installed at the bottom of the upper mold, and a second connecting edge integrally installed at the top of the lower mold, wherein the upper mold and the lower mold are closed, locked and separated by the first connecting edge and the second connecting edge;

[0007] A linkage component is provided on the first mating edge, and a locking component is rotatably connected to the bottom of the first mating edge at equal angles. The linkage component drives the locking component to rotate synchronously, and the locking component is inserted into the mating groove through the bottom of the linkage component. The mating groove is correspondingly opened at equal angles on the top of the second mating edge.

[0008] A sealing edge is installed at the bottom of the first mating edge, and the sealing edge is engaged with a groove, which is located at the top of the second mating edge.

[0009] Furthermore, the linkage includes a first ring that is slidably connected through the top of the first mating edge, a second ring that is fixed to the bottom of the first ring, and the second ring that is slidably connected to the inside of the edge of the first mating edge by a spring. The second ring and the spring together form an elastic sliding structure.

[0010] Furthermore, the second ring has protrusions fixed at equal angles on its side surface. The outer side of the protrusions is slidably connected to the spiral groove. The spiral groove is opened on the upper outer side of the locking member. The upper part of the locking member is rotatably connected to the inside of the first mating edge. The locking member forms a rotating structure through the protrusions and the spiral groove.

[0011] Furthermore, the locking element is configured as an inverted "T" shape, with the locking element corresponding one-to-one with the protrusion and the mating groove.

[0012] Furthermore, the docking groove inlet is configured as a rectangular structure, the bottom of the docking groove is configured as a circular structure, and the bottom of the locking member is vertically connected to the docking groove inlet after locking.

[0013] Furthermore, a locking plate is symmetrically hinged to the top of the first mating edge, and a torsion spring is installed at the rotating part of the locking plate. The locking plate is configured with an "L" shaped structure, and the top of the locking plate abuts against the top of the first ring.

[0014] Furthermore, a sealing block and a sealing ring are respectively installed inside the docking groove and in the recess, and the sealing ring has a "U" shaped cross-section.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The rotational molding mold for this hot rotational molding lining allows for quick disassembly and removal of the upper and lower molds by simple pulling during use. This convenient and fast operation helps improve the production efficiency of hot rotational molding linings. At the same time, the joints can be reinforced with a seal during installation.

[0017] 1. Further, the first ring drives the second ring to move upward, thereby compressing the spring. The second ring drives the protrusion to move upward synchronously. The protrusion drives the locking member to rotate synchronously through the spiral groove. After the locking member rotates, its bottom is in a state parallel to the entrance of the docking groove. Then, the first docking edge and the second docking edge are docked. The locking member is inserted into the inside of the docking groove. After the first ring is released, the spring drives the second ring and the first ring to reset and move downward due to the elastic force. After the second ring resets, the protrusion drives the locking member to rotate through the spiral groove. The bottom of the locking member will rotate to a state perpendicular to the entrance of the docking groove, thereby making it convenient and firm to dock and install the upper mold and the lower mold.

[0018] 2. Furthermore, the locking component forms a rotating structure through the protrusion and the spiral groove. The locking component is set as an inverted "T" shaped structure. The locking component, the protrusion, and the docking groove are positioned one-to-one. The entrance of the docking groove is set as a rectangular structure, and the bottom of the docking groove is set as a circular structure, so that the upper mold and the lower mold can be docked and installed by rotating.

[0019] 3. Furthermore, after the locking component mates with the mating groove, the sealing block can seal the connection, and after the sealing edge mates with the groove, the sealing ring can perform a secondary sealing treatment on the connection, thereby improving the sealing performance when the first mating plate and the second mating edge mate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: Please refer to Figure 1 - Figure 8 This utility model provides the following technical solution: a rotational molding mold for hot rotational molding lining, including an upper mold 1, a lower mold 2 connected to the lower part of the upper mold 1, a first connecting edge 3 integrally installed at the bottom of the upper mold 1, and a second connecting edge 4 integrally installed at the top of the lower mold 2. The upper mold 1 and the lower mold 2 are closed, locked, and separated through the first connecting edge 3 and the second connecting edge 4. A linkage is provided on the first connecting edge 3, and a locking element 10 is rotatably connected to the bottom of the first connecting edge 3 at equal angles. The linkage drives the locking element 10 to rotate synchronously, and the locking element 10 is inserted into the connecting groove 11 through the bottom of the linkage. The connecting groove 11 is correspondingly opened at equal angles at the top of the second connecting edge 4. A sealing edge 14 is installed at the bottom of the first connecting edge 3, and the sealing edge 14 is engaged with a groove 15. The groove 15 is opened at the top of the second connecting edge 4.

[0031] In use, the first mating edge 3 and the second mating edge 4 on the opposite surfaces of the upper mold 1 and the lower mold 2 are connected. The locking part 10 is controlled to rotate synchronously by the linkage. After the locking part 10 rotates, its bottom will be in a state parallel to the entrance of the mating groove 11. Then, the locking part 10 is inserted into the mating groove 11. The linkage is released, and the locking part 10 is reset and rotated. The locking part 10 and the mating groove 11 are in a state of vertical contact, thereby making it easy and quick to connect and fix the upper mold 1 and the lower mold 2. When the first mating edge 3 and the second mating edge 4 are connected, the sealing edge 14 will be engaged in the groove 15, thereby sealing the connection.

[0032] Example 2:

[0033] Based on Embodiment 1, a linkage component is also disclosed; please refer to [reference needed]. Figure 2 - Figure 8As shown, its specific structure is as follows: The linkage includes a first ring 5 that is slidably connected to the top of the first mating edge 3. A second ring 6 is fixed to the bottom of the first ring 5. The second ring 6 is slidably connected to the inside of the edge of the first mating edge 3 by a spring 7. The second ring 6 forms an elastic sliding structure through the first ring 5 and the spring 7. A protrusion 8 is fixed at equal angles on the side of the second ring 6. The outer side of the protrusion 8 is slidably connected to a spiral groove 9. The spiral groove 9 is opened on the upper outer side of the locking member 10. The upper part of the locking member 10 is rotatably connected to the inside of the first mating edge 3. The rotating structure is formed by the protrusion 8 and the spiral groove 9. The locking member 10 is set as an inverted "T" shaped structure. The locking member 10 corresponds one-to-one with the protrusion 8 and the docking groove 11. The entrance of the docking groove 11 is set as a rectangular structure and the bottom of the docking groove 11 is set as a circular structure. After the locking member 10 is locked, its bottom is vertically connected to the entrance of the docking groove 11. The top of the first docking edge 3 is symmetrically hinged with a locking plate 12. A torsion spring 13 is installed at the rotating part of the locking plate 12. The locking plate 12 is set as an "L" shaped structure. The top of the locking plate 12 abuts against the top of the first ring 5.

[0034] In use, first rotate the locking plate 12 at the top of the first mating edge 3 outwards. After the locking plate 12 rotates, it reverses the torsion spring 13, thereby freeing up the movement space of the first ring 5. Then, pull the first ring 5 up. The first ring 5 will drive the second ring 6 to move upwards simultaneously, thereby compressing the spring 7. After the second ring 6 moves upwards, it will drive the protrusion 8 to move upwards simultaneously. The protrusion 8 will drive the locking member 10 to rotate synchronously through the spiral groove 9. After the locking member 10 rotates, its bottom will be in a state parallel to the entrance of the mating groove 11. Then, mate the first mating edge 3 and the second mating edge 4, and insert the locking member 10 into the mating groove. Inside the groove 11, after the first ring 5 is released, the spring 7, due to its elastic force, drives the second ring 6 and the first ring 5 to reset and move downward. After the second ring 6 is reset, the protrusion 8 drives the locking member 10 to rotate through the spiral groove 9. The bottom of the locking member 10 will rotate to a state perpendicular to the entrance of the docking groove 11, thereby making it easy and firm to dock and install the upper mold 1 and the lower mold 2. Then, the locking plate 12 is released, and the torsion spring 13 drives the locking plate 12 to rotate, thereby pressing the top of the first ring 5 again, thereby reinforcing the connection. When separating the upper mold 1 and the lower mold 2, the above operation can be repeated.

[0035] Example 3:

[0036] Based on Embodiment 2, a sealing block 16 and a sealing ring 17 are also disclosed. Please refer to [reference needed]. Figure 2 - Figure 3 , Figure 5 and Figure 8As shown, its specific structure is as follows: a sealing block 16 and a sealing ring 17 are respectively installed inside the docking groove 11 and the embedded groove 15. The cross section of the sealing ring 17 is set as a "U" shaped structure.

[0037] When in use, after the locking member 10 is mated with the mating groove 11, the sealing block 16 can seal the connection. After the sealing edge 14 is mated with the groove 15, the sealing ring 17 can perform a secondary sealing treatment on the connection, thereby improving the sealing performance when the first mating edge 3 and the second mating edge 4 are mated.
