Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a structure that facilitates die installation. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). During the process, a moving die mounted on a press applies pressure to the material placed on a fixed die, causing it to separate or undergo plastic deformation to obtain the desired part.

[0003] After a period of use, molds require regular disassembly, cleaning, and maintenance. However, existing mold installation methods mostly involve bolt fixing, where the bottom of the fixed mold is bolted to the table, and the top of the moving mold is bolted to the square plate at the bottom of the stamping power mechanism. Disassembling, cleaning, and maintaining the mold is time-consuming and labor-intensive, and the removed bolts are not easy to store and are prone to being lost, which can affect subsequent mold processing. Utility Model Content

[0004] The purpose of this utility model is to provide a structure that facilitates mold installation, thereby solving the problem of inefficient operation when disassembling and assembling stamping dies.

The driving component includes a lead screw with its middle and two ends respectively rotatably fitted in the shaft holes and the two sides of the middle section having opposite thread directions, and a rotating wheel fixed to one end of the lead screw. The two sides of the middle section of the lead screw are respectively threadedly fitted with the corresponding threaded sleeves.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: A slot 2.1 extending laterally is provided on the top surface of the stamping equipment table at the installation position of the fixed mold 1 and in the middle of the top surface of the moving mold 2. Fixing plates 1.1 are fixed to the middle of the bottom ends of the two side walls of the fixed mold 1, and the thickness of the fixing plates 1.1 is the same as that of the bottom square plate of the stamping power mechanism.

[0022] The fixing mechanism 3 includes a plate 3.1 extending laterally, a pair of clamping blocks 3.2 slidingly mounted on both sides of the middle of the plate 3.1, and a driving component 3.3 that drives the two clamping blocks 3.2 to move synchronously towards each other or synchronously back to back through a screw and nut mechanism. The plate 3.1 has opposing strip-shaped slots 3.1.1 on both sides of its middle section. The side walls of the strip-shaped slots 3.1.1 have shaft holes 3.1.2. T-shaped slide rails extending laterally are fixed to the top surface of the plate 3.1 at positions front and rear of the strip-shaped slots 3.1.1. A positioning screw hole 3.1.4 is provided on the front side of the middle section of one end face of the plate 3.1.

[0023] The clamping block 3.2 includes a clamping plate 3.2.1, a pressure plate 3.2.2 integrally formed on the top of the inner wall of the clamping plate 3.2.1 and extending horizontally, a slider 3.2.4 integrally formed on the bottom of the middle part of the clamping plate 3.2.1 and slidably engaged with the strip groove 3.1.1, and a threaded sleeve 3.2.5 fixedly fitted in the middle of the slider 3.2.4. The outer sides of the front and rear ends of the clamping plate 3.2.1 are respectively fixed with locking blocks 3.2.3 that slidably engage with the T-shaped slide rail 3.1.3. When the clamping block 3.2 moves to its innermost position towards the fixed plate 1.1 and the bottom square plate of the stamping power mechanism, the pressure plate 3.2.2 precisely presses against the top surface of the fixed plate 1.1 and the top surface of the square plate, and the clamping plate 3.2.1 clamps tightly against the outer walls of the fixed plate 1.1 and the square plate. To achieve a tighter packaging effect, the top surfaces of the fixing plate 1.1 and the square plate are respectively provided with an outer slope that is lower than the inner slope, and the bottom surface of the pressure plate 3.2.2 is provided with a matching slope structure.

[0024] The driving component 3.3 includes a lead screw 3.3.1, with its middle and two ends respectively rotatably fitted into the shaft hole 3.1.2, and the two sides of the middle section having opposite thread directions; and a rotating wheel 3.3.2 fixed to one end of the lead screw 3.3.1. The two sides of the middle section of the lead screw 3.3.1 are respectively threaded into the corresponding threaded sleeves 3.2.5. A crank handle 3.3.3 is vertically connected to the outer edge of the outer wall of the rotating wheel 3.3.2, wherein the inner end of the crank handle 3.3.3 is fixedly connected to a fixed... Positioning screw 3.3.5, and wheel 3.3.2 are fixed at the outer edge of the wheel with an internally threaded tube 3.3.4 extending along its axial direction. Positioning screw 3.3.5 is threadedly sleeved with internally threaded tube 3.3.4, and the inner end of positioning screw 3.3.5 is threadedly sleeved with positioning screw hole 3.1.4, which ensures that the distance between the positioning screw 3.3.5 and the central axis of lead screw 3.3.1 is equal to the distance between the central axis of shaft hole 3.1.2 and positioning screw hole 3.1.4.

[0025] In summary, when installing the fixed mold 1, the plate 3.1 is clamped onto the table surface with a slot 2.1, the end of the slot 2.1 on the table surface extending to its end face, i.e., the rotating wheel 3.3.2 is located on the outer side of the table surface sidewall. The plate 3.1 is fixed to the slot 2.1 on the table surface using hexagonal socket head cap screws. The fixed mold 1 is placed on the corresponding position on the top surface of the middle of the plate 3.1, and then the rotating wheel 3.3.2 is rotated by the crank handle 3.3.3. The rotating wheel 3.3.2 drives the lead screw 3.3.1 to rotate, so that the clamping block 3.2 is driven to slide towards the center through the threaded sleeve 3.2.5 and the slider 3.2.4 until the pressure plate 3.2.2 presses against the top surface of the fixed plate 1.1, and the inner sidewall of the clamping plate 3.2.1 is pressed tightly against the outer sidewall of the pressure plate 3.2.2, thus completing the fixed installation of the fixed mold 1. By rotating the wheel 3.3.2 in the opposite direction, the clamping blocks 3.2 on both sides can be moved to the sides until they lose their function of pressing on the fixed plate 1.1.

[0026] Accordingly, under normal circumstances, the moving mold 2 and the upper fixing mechanism 3 are pre-assembled structures, that is, the plate 3.1 is snapped into the slot 2.1 on the top surface of the moving mold 2, and the plate 3.1 is provided with a countersunk hole, in which an internal hexagon bolt is installed to achieve a fixed connection between the plate 3.1 and the moving mold. When installing with the square plate at the bottom of the stamping power mechanism, the square plate is lowered to the position where the bottom surface is in contact with the top surface of the plate 3.1, and then the rotating wheel 3.3.2 is rotated so that the clamping blocks 3.2 on both sides press and clamp the square plate on both sides, thereby completing the fixed connection between the moving mold 2 and the square plate at the bottom of the stamping power mechanism.

[0027] In addition, when the fixed mold 1 and the moving mold 2 are fixed and installed, the rocker handle 3.3.3 rotates to the position that is exactly opposite to the corresponding positioning screw hole 3.1.4. The rocker handle 3.3.3 rotates relative to the rotating wheel 3.3.2 until the positioning screw 3.3.5 is threaded into the corresponding positioning screw hole 3.1.4, so as to achieve the locking effect on the rotating wheel 3.3.2.
