Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, and in particular to a rotational molding clamping support column structure. Background Technology

[0002] In the fields of machinery manufacturing and mold processing, mold clamping and support is a crucial technical aspect. With the continuous development of industrial production, higher demands are placed on the efficiency, stability, and applicability of mold clamping and support. Efficient and reliable mold clamping and support structures can significantly improve production efficiency, reduce production costs, and ensure product quality stability, playing an indispensable role in many industrial production scenarios. It not only affects the processing accuracy and efficiency of individual molds but also has a direct impact on the smooth operation of the entire production line. For example, in industries such as automotive parts manufacturing and plastic product production, the quality of mold clamping and support technology directly determines product quality and production efficiency.

[0003] In the past, to clamp and support molds, screws were typically used to lock pressure plates onto the worktable to fix the mold in place. This method uses the tightening force of the screws to press the pressure plate firmly against the mold, thus achieving fixation. Furthermore, the height of traditional mold clamping and support structures is often fixed and not adjustable. When facing processing scenarios with different height requirements, different specifications of support structures must be replaced. Moreover, traditional clamping and support structures are mostly only suitable for flat worktables and cannot be used on non-flat worktables. While these traditional clamping and support methods met the production needs to a certain extent at the time, their limitations have gradually become apparent with industrial development.

[0004] However, the traditional screw-locking clamping plate method has significant drawbacks. The process is cumbersome, requiring each screw to be tightened individually, resulting in low efficiency in clamping and disassembling molds. Furthermore, the traditional clamping support structure is not height-adjustable, necessitating frequent replacements of the support structure when clamping molds with varying height requirements, wasting considerable time and effort. In addition, the traditional structure can only be installed on a flat worktable, failing to adapt to work surfaces of arbitrary shapes, severely limiting its application range.

[0007] By adopting the above technical solution, the rotational molding clamping support column structure designed in this utility model uses magnets to attach the mold to the worktable to fix it during use, which is more efficient and convenient than the previous method of screw locking the pressure plate. In addition, the height of the mold can be adjusted by the threaded connection between the two ends of the positive and negative thread connecting rod and the mold and magnet, avoiding the problems of non-adjustable height and low efficiency in the past.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] This utility model discloses a rotational molding clamping support column structure, such as Figure 1 As shown, the device includes a mold 1, a forward and reverse threaded connecting rod 2, and a magnet 3. The forward and reverse threaded connecting rod 2 is located on both sides of the mold 1, and its bottom is connected to the magnet 3. The mold 1 is fixed by being attracted to the worktable by the magnet 3. The two ends of the forward and reverse threaded connecting rod 2 are threadedly connected to the mold 1 and the magnet 3, respectively, which can adjust the height of the mold 1. This achieves the effect of efficiently clamping the mold 1 and adapting to different height requirements. This is because the magnet 3 attraction method is more convenient than the traditional screw locking plate, and the threaded connection of the forward and reverse threaded connecting rod 2 can flexibly adjust the height, avoiding frequent replacement of the support structure.

[0024] Specifically, mold 1 includes a first threaded sleeve 4 and a hinge structure 7. The first threaded sleeve 4 is mounted on mold 1 and has a threaded connection hole, which allows the first threaded sleeve 4 to be threadedly connected to one end of the positive and negative thread connecting rod 2. The first threaded sleeve 4 is typically made of metal and is cylindrical in shape, with threads on its inner wall that are compatible with the positive and negative thread connecting rod 2. The hinge structure 7 is located between mold 1 and a third threaded sleeve 6, and includes a hinge shaft 71 fixed to mold 1. The third threaded sleeve 6 is fitted onto the hinge shaft 71 and rotates with it. The hinge shaft 71 is generally a cylindrical metal shaft, connected to mold 1 by welding or other fixing methods, and the third threaded sleeve 6 can rotate around the hinge shaft 71.

[0025] The first threaded sleeve 4 is fixed to the mold 1 by welding or bolting, and is connected to the positive and negative thread connecting rod 2 by threaded engagement, so that the positive and negative thread connecting rod 2 can be firmly installed on the mold 1. The hinge structure 7 allows the third threaded sleeve 6 to rotate relative to the mold 1, thereby allowing the front positive and negative thread connecting rod 2 to rotate, ensuring that the magnet 3 at its bottom can also be fixed on the inclined plane.

[0026] Specifically, the positive and negative thread connecting rod 2 includes a rod body and threads at both ends. The rod body is made of metal, with positive and negative threads at both ends, respectively, which mate with the threaded sleeves on the mold 1 and magnet 3. The rod body is straight, but a rod body with a certain degree of curvature can be used as an alternative, ensuring thread compatibility. The threads at both ends connect with the threads of the threaded sleeves on the mold 1 and magnet 3, enabling height adjustment. When the positive and negative thread connecting rod 2 is rotated, the distance between the mold 1 and magnet 3 changes because the threads at both ends are in opposite directions, thereby adjusting the height of the mold 1.

[0027] Specifically, magnet 3 includes a second threaded sleeve 5, a V-groove 8, and a knob 9. The second threaded sleeve 5 is mounted on magnet 3 and has a threaded connection hole. This threaded connection hole is used to thread the second threaded sleeve 5 to one end of the positive and negative thread connecting rod 2. The construction of the second threaded sleeve 5 is similar to that of the first threaded sleeve 4; it is also a metal cylinder with matching threads on its inner wall. An alternative feature could be an integral threaded structure, where the threads are directly machined onto magnet 3. The V-groove 8 is located at the bottom of magnet 3 and is V-shaped. This design allows magnet 3 to better conform to non-planar workbenches, such as workbenches with a certain curvature. An alternative feature could be a U-shaped groove or other groove shapes. The knob 9 is mounted on magnet 3 and magnetically couples with the permanent magnet inside magnet 3 to adjust the orientation of the permanent magnet. Knob 9 is generally made of plastic or metal. Rotating knob 9 changes the direction of the magnetic field of the permanent magnet, thereby controlling the attraction of magnet 3.

[0028] The second threaded sleeve 5 is connected to the magnet 3 by welding or other fixing methods, and is connected to the positive and negative thread connecting rod 2 by threaded engagement. The V-groove 8 is machined directly on the bottom of the magnet 3, forming an integral structure with the magnet 3. The knob 9 is magnetically coupled to the permanent magnet inside the magnet 3, enabling adjustment of the permanent magnet's orientation.

[0029] The implementation principle of this embodiment is as follows: The rotational molding clamping support column structure of this embodiment replaces the traditional screw-locking pressure plate method with the attraction of magnet 3, which greatly improves the efficiency of clamping and disassembling mold 1. The threaded connection design of the positive and negative thread connecting rod 2 can flexibly adjust the height of mold 1 to adapt to processing scenarios with different height requirements, avoiding the trouble of frequently changing the support structure. The design of the hinge structure 7 and V-groove 8 allows this structure to adapt to non-planar worktables, expanding its application range. The adjustment function of knob 9 for the orientation of permanent magnet can control the magnitude of the attraction force according to actual needs, further improving practicality and flexibility, and representing a significant improvement and enhancement compared to traditional technology.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
