Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping device for a hot forming mold. Background Technology

[0002] A mold (mú jù) is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. It is often called the "mother of industry." Mold shaping refers to the process where the shape of the workpiece is basically fixed, requiring only minor adjustments to individual parts, such as the shape of the edges and corners, and the radius (R). Forming, on the other hand, involves taking a flat sheet of material and, through processes such as bending, stretching, and flanging, shaping the workpiece into a predetermined form. In existing technologies, different shaped molds require different clamping devices for easy transfer to a suitable workstation for processing; however, general clamping devices can only be customized, resulting in poor compatibility.

[0003] To address the aforementioned problems, this application proposes a clamping device for a thermal forming mold. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figure 1-3 As shown, the present invention proposes a clamping device for a hot forming mold, which includes a handle 1 and a clamping part 5.

[0026] The clamping part 5 includes an elastic band 51 and a limiting part 52; the elastic band 51 is arranged in a ring structure; both ends of the elastic band 51 are inserted into the handle 1; the limiting part 52 is arranged against the inner side wall of the elastic band 51; a steel wire for locking the elastic band 51 is inserted through the limiting part 52; the elastic band 51 is composed of multiple independent spindle-shaped elastic parts arranged in combination, and the steel wire passes through the elastic parts in sequence.

[0027] Multiple adsorption elements 53 are provided on the outer periphery of the elastic part. The adsorption elements 53 are arranged in the shape of a frustum. The adsorption elements 53 contact the workpiece and cooperate to form a suction cup structure.

[0028] A button 2 is provided on the handle 1; a sleeve 3 is provided on the side of the handle 1 away from the clamping part 5. The sleeve 3 is a threaded tube and an adjusting bolt 4 is provided on the sleeve 3; a steel wire inserted inside the elastic band 51 is inserted into the sleeve 3 and fixedly installed on the inner wall of the sleeve 3.

[0029] In an optional embodiment, a pressing plate 21 is provided inside the handle 1, and a button 2 is located on the top of the pressing plate 21; a retaining seat 22 is provided at the bottom of the pressing plate 21, and the retaining seat 22 is arc-shaped; a steel wire passes through the retaining seat 22. A support plate 23 is provided at the bottom of the retaining seat 22, and an elastic element 24 is provided at the bottom of the support plate 23. A support base 25 is provided below the support plate 23; the bottom of the elastic element 24 is fitted with the support base 25; the elastic element 24 moves up and down in the vertical direction.

[0030] It should be noted that when button 2 on handle 1 is pressed down, the compression plate 21 and the card holder 22 move downward together, the elastic element 24 remains compressed, and the bottom of the support plate 23 remains in contact with the top of the support base 25. At this time, the steel wire passes through the card holder 22, and the steel wire and the steel wire inside the clamping part 5 are at the same horizontal height. At this time, the sleeve 3 can be easily pulled out to keep the clamping part 5 in a tight state. After button 2 is released, the card holder 22 moves upward under the elastic force of the elastic element 24, and the steel wire is pulled upward. The steel wire and the bottom of the card holder 22 remain in a state of friction, which is beneficial for limiting the steel wire.

[0031] In an optional embodiment, the support plate 23 and the support base 25 are magnetically attracted to each other.

[0032] It should be noted that the support plate 23 is connected to the support base 25 by magnetic attraction, which makes it easy to pull the steel wire to adjust the tightness of the clamping part 5, thus making it suitable for clamping molds of different shapes and sizes.

[0033] In an optional embodiment, the handle 1 is configured in an arc shape, and the outside of the handle 1 is covered with an elastic rubber component.

[0034] It should be noted that the arc-shaped handle 1 is more comfortable to hold, and the elastic rubber parts wrapped around the outside of the handle 1 serve to prevent slipping.

[0035] In an optional embodiment, the clamping part 5 is bent to a suitable angle as needed.

[0036] In an optional embodiment, the sleeve 3 is provided with an annular limiting member on the side facing the adjusting bolt 4, and the adjusting bolt 4 is limited in position in cooperation with the limiting member.

[0037] It should be noted that the limiting element provided on the outer periphery of the sleeve 3 can limit the adjusting bolt 4 and prevent the adjusting bolt 4 from falling off the sleeve 3.

[0038] In this invention, the clamping part 5 is sleeved onto the outer periphery of the mold to be clamped and fixed; one hand holds the handle 1, while the thumb presses down on the button 2; at this time, the extrusion plate 21 moves downward together with the card holder 22, the elastic element 24 remains compressed, and the bottom of the support plate 23 remains in contact with the top of the support base 25; at this time, the steel wire passes through the card holder 22, and the steel wire and the steel wire inside the clamping part 5 are at the same horizontal height, so the sleeve 3 can be easily pulled out to keep the clamping part 5 in a tight state; after releasing the button 2, the card holder 22 moves upward under the elastic force of the elastic element 24. When the steel wire is pulled upwards, it maintains friction with the bottom of the clamping seat 22, which helps to limit the movement of the steel wire. When the sleeve 3 is pulled outwards, the steel wire moves outwards as well, and the corresponding extrusion part 5 contracts and adheres to the outer periphery of the mold. The adsorption element 53 on the extrusion part 5 receives pressure and closely adheres to the outer periphery of the mold, forming a suction cup structure. After tightening, rotating the adjusting bolt 4, when the adjusting bolt 4 contacts the bottom of the handle 1, can position the extended sleeve 3, thus ensuring that the clamping part 5 is in a tightened state. At this time, the mold can be transferred and transported through the clamping device. This utility model can conveniently clamp molds, has good compatibility, and is suitable for molds of different sizes.

[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
