Description

Technical Field

[0001] The invention relates to the technical field of adjustable moulds, in particular to an adjustable mould. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". It is a tool that makes the blank into a part with a specific shape and size under the action of external force. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch) according to the contour shape. The use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally consists of two parts: a movable mold and a fixed mold (or a punch and a die), which can be separated or combined.

This mechanism is like a precise navigation system, which provides a stable and accurate movement path for the clamping part, ensuring that the clamping action can be carried out normally and reach the predetermined position accurately every time. Such a design not only improves the overall stability of the equipment, but also provides a strong guarantee for the precise processing of workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Furthermore, the number of threaded rods 24 is two, and the two threaded rods 24 are symmetrically arranged on both sides of the base 1. Opposite threads are arranged on both sides of the surfaces of the two threaded rods 24. Rubber protrusions are fixedly connected to the surface of the clamping member 21. The number of rubber protrusions is several, and the several rubber protrusions are evenly distributed in the base 1.

[0032] Furthermore, a vertical plate 202 is fixedly connected to the bottom of the tooth plate 25, and fixed blocks 26 are fixedly connected to both sides of the surface of the vertical plate 202. A support rod 23 is slidably connected inside the fixed block 26. The support rod 23 is fixedly connected to the front inner wall of the base 1.

A support frame 29 is fixedly connected to the rear surface of the support rod 23, and a mounting block 201 is fixedly connected in the middle of the support frame 29. The support frame 29 is fixedly connected to the surface of the base 1, and the support frame 29 is designed in an irregular shape.

[0033] Furthermore, the cooling mechanism 3 includes a fixing frame 34, which is fixedly connected to the top of the tooth plate 25, and a positioning plate 31 is fixedly connected to the surface of the fixing frame 34, and an arc plate 36 is fixedly connected to the side of the positioning plate 31 away from the fixing frame 34, and a placement plate 32 is fixedly connected to the side of the arc plate 36 away from the positioning plate 31, and a first transverse plate 33 is arranged at the bottom of the placement plate 32, and both sides of the top of the first transverse plate 33 are fixedly connected to limiting plates 35, and the number of limiting plates 35 is two, and the two limiting plates 35 are symmetrically arranged, and the two limiting plates 35 are arranged on the rear side of the base 1, and the first transverse plate 33 is fixedly connected between the two positioning plates 31, and a rectangular plate 39 is fixedly connected to the top of the placement plate 32, and a placement block 37 is fixedly connected between the two rectangular plates 39, and a threaded hole is opened in the placement block 37, and an adjusting bolt 38 is threadedly connected in the threaded hole, and the adjusting bolt 38 is rotatably connected to the rear side of the base 1.

[0034] Furthermore, the guide mechanism 4 is mainly composed of a slide groove, which is carefully opened on the front side of the base 1, and is exquisitely designed and stable. Inside the slide groove, a second cross plate 43 is assembled by a sliding connection. This design enables the second cross plate 43 to slide smoothly in the slide groove, ensuring the smoothness and stability of the movement. In order to further enhance the guiding effect, a second connecting plate 42 is also fixedly connected to the bottom of the second cross plate 43, and the connecting plate is cleverly arranged on the front side of the base 1, which is closely matched with the overall structure. In the actual working process, when the clamping member 21 needs to move, this carefully designed guide mechanism 4 plays a key role. The mounting members 41 are fixedly connected to both sides of the surface of the guide rod 44, and the mounting members 41 are fixedly connected to the front side surface of the base 1. The second cross plate 43 slides smoothly inside the slide groove, providing a stable moving path for the clamping member 21. At the same time, the second connecting plate 42 also slides smoothly on the surface of the guide rod 44. This dual guiding mechanism not only ensures that the clamping member 21 can move stably along the predetermined path, but also greatly improves the accuracy and reliability of the clamping action. In general, the design of this guide mechanism 4 fully considers the needs in practical applications, and provides a stable and accurate moving path for the clamping member 21 through the dual guiding mechanism, thereby ensuring that the clamping action can be carried out normally and accurately, greatly improving the performance and stability of the overall equipment.

[0035] In actual operation, when this device is used, the workpiece is first accurately placed between the clamps 21 on both sides, and the cooling plate is further properly placed between the limit plates 35 on both sides. Then, by carefully turning the adjustment bolts 38, this operation can cleverly drive the first cross plate 33 to slowly move toward the side of the base 1 until the cooling plate fits tightly with the base 1. This ingenious design realizes efficient cooling heat transfer to the workpiece and significantly improves the production efficiency of the workpiece. While the first cross plate 33 moves steadily, the tooth plate 25 also moves toward the front side in an orderly manner. During the movement of the tooth plate 25, the flat gear 22 begins to rotate flexibly. Thanks to the rotation of the flat gear 22, the threaded rods 24 on both sides are also driven and begin to rotate synchronously. As the threaded rods 24 on both sides rotate, they drive the clamps 21 on both sides to move steadily in the direction of approaching each other, thereby achieving a stable clamping and fixing of the workpiece. This mechanism effectively avoids the phenomenon of workpiece displacement during the processing. At the same time, it can flexibly adapt to workpieces of different sizes and thicknesses, bringing great convenience to the production of workpieces and further expanding the practicality and application scope of the device. It is worth noting that during the movement of the tooth plate 25, the fixed block 26 slides smoothly on the surface of the support rod 23. This design ensures the stability and accuracy of the tooth plate 25 during the movement and effectively prevents the tooth plate 25 from being offset during movement. Similarly, when the clamping member 21 is moving, the second cross plate 43 slides smoothly inside the slide groove, and the second connecting plate 42 also slides smoothly on the surface of the guide rod 44. This dual guide mechanism provides a stable moving path for the clamping member 21, ensuring that the clamping action can be performed normally and accurately.
