Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold suitable for multiple sizes. Background Art

[0002] Molds are various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, and stamping. They are composed of various parts, and different mold types have different structures. For example, injection molds are primarily used to form plastic products and generally include key components such as the cavity and core. Plastic raw materials are heated and melted, then injected into the mold cavity, where they are cooled and solidified to produce the plastic product. Stamping molds are used to process sheet metal, using the combination of a punch and a die to perform operations such as punching and blanking.

[0003] Punching dies are used to punch holes in sheet materials. They consist of a punch, die, stripper plate, and die base. During operation, the sheet is placed on the die, and a press pushes the punch downward, causing the sheet to plastically deform. The punch then penetrates the sheet and enters the die hole, completing the punching process. The stripper plate then releases the sheet. This fixed die is commonly used in the mechanical and metalworking industries, but its versatility is limited. Changing the die when production tasks change is cumbersome, resulting in reduced efficiency. Utility Model Content

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Combined with attachment Figure 4A mold suitable for multiple sizes, characterized by comprising: a base 1 with a through-hole in the middle, a removable elastic top sheet 12 in the cavity, and an adjustable position of the elastic top sheet 12; a square hole in the middle of the base 1, a supporting edge in the square hole; the external thread at the bottom of the elastic top sheet 12 cooperates with the threaded hole in the base 1, making installation and removal convenient. The lower half slide 10 and the upper half slide rod 11 structure are equipped with a strong spring 13. During the punching process, when the punch is pressed down, the slide rod 11 can retract. After the punch leaves, the top sheet 12 can eject the material under the action of the spring, ensuring the punching quality and adapting to the ejection requirements of molds of different sizes.

[0022] Combined with attachment Figure 2 The lower mold 2 is slidably fitted with the side wall of the square hole and placed on the supporting edge. A mold hole 5 is provided on it for the elastic top plate 12 to be ejected. A pressing structure for pressing the lower mold 2 is provided on the base 1. The pressing structure includes a pressing plate 14 that is rotatably arranged on the front and rear sides of the base 1. Two pressing plates are arranged on the same side. The protruding end surface of the pressing plate 14 is a beveled surface, and the adjacent beveled surfaces are respectively provided with magnetic blocks 15 with different magnetic properties. The lower mold 2 can be easily fixed. When the pressing plate 14 rotates closer, the magnetic blocks 15 attract each other and can stably press the lower mold 2. This structure is simple to operate when replacing the lower mold 2. It is only necessary to overcome the attraction of the magnetic blocks 15 and rotate the pressing plate 14. A pull button 16 is provided on the pressing plate 14. The pull button 16 provides a good force application point, improves operating efficiency, and also avoids the inconvenience that may be caused by direct contact with the pressing plate 14.

[0023] Combined with attachment Figure 1 and attached Figure 3 The upper working plate 3 is located above the base 1 and has side bars 6 on both sides below. A square plate 7 below the side bars 6 is bolted to the base 1. A cylinder 8 is fixed to the middle of the upper working plate 3. The protruding end of the cylinder 8 passes through the upper working plate 3 and is connected to a mounting plate 9. The upper mold 4 is detachably located below the mounting plate 9 and is compatible with the lower mold 2 for punching operations. The position of the threaded hole matches the position of the die hole 5, allowing the elastic top sheet 12 to accurately correspond to the die hole 5 of the lower mold 2. This ensures that during the punching process, the top sheet 12 can accurately apply an upward force to the material, effectively preventing the material from getting stuck in the die hole 5, and improving the reliability of the mold and the punching efficiency.

[0024] Working principle: When in use, first adjust the position of the elastic top plate 12 according to the punching size requirements through the threaded hole under the base 1 and the threaded positioning of the slide 10, and slide the lower mold 2 along the side wall of the square hole of the base 1 and place it on the support edge. This design makes it easy to replace the lower mold in the square hole. By pulling the button 16, the pressure plate 14 is rotated and the lower mold 2 is fixed by the attraction of the magnetic block 15. Then the upper working plate 3 is fixed to the base 1 with bolts through the square plate 7 under the side rod 6, and a suitable upper mold 4 is installed under the mounting plate 9. The design of this mounting plate facilitates the replacement of the upper mold and is simple and convenient to operate. Start the cylinder 8 to make the upper mold 4 cooperate with the lower mold 2 to punch. During the punching process, the slide rod 11 of the elastic top plate 12 can retract. After completion, the top plate 12 ejects the material under the action of the spring. The entire device is suitable for molds of various sizes and can meet the needs of different punching operations.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.

[0026] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
