[0002] A stamping die refers to a metal processing process equipment that processes materials or semi-finished products into parts during the cold stamping process of plastic materials, and is an essential part in the modern industrialization process.

[0003] The existing publicly disclosed patent (publication number: CN217290068U) discloses a stamping die convenient for adjustment, including a die frame, guide shaft holes, a convenient adjustment groove and a convenient adjustment unit; a plurality of guide shaft holes are opened on the upper surface of the die frame; a convenient adjustment groove is opened on the upper surface of the die frame; a convenient adjustment unit is arranged in the convenient adjustment groove; the convenient adjustment unit includes an adjustment threaded hole, an adjustment threaded shaft and an adjustment hexagonal column; through the sliding fit of the convenient adjustment groove and the replaceable base, and then cooperating with the adjustment threaded shaft and the adjustment hexagonal column, the replaceable base can be extruded and fixed in the convenient adjustment groove through the threaded connection of the adjustment threaded shaft and the adjustment threaded hole, and at the same time, replaceable bases and lower die cores of different sizes are adapted, which is suitable for the manufacture of low-precision stamping dies, with low cost and strong versatility.

[0004] In the above stamping die, there is a lack of a buffer structure, resulting in easy deformation of the die itself during the stamping process. At present, the buffer structures used in stamping dies are mostly springs and are arranged at the guiding structure. The stability of the springs is not good, the buffer force can only be determined by the material of the springs themselves, and arranging them at the guiding position will cause damping to the stamping force. For this reason, the utility model proposes a mold assembly convenient for adjustment to improve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mold assembly convenient for adjustment to solve the problems in the above background technique that the existing mold assembly lacks a buffer protection structure, or the damping value of the arranged buffer protection structure is fixed and inconvenient to adjust, and the practicability is low.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A mold assembly convenient for adjustment, including a stamping template; a stamping die core and a receiving block are fixed in the middle of the upper side of the stamping template, a stamping table is arranged above the stamping die core and the receiving block, a stamping head is fixed in the middle of the stamping table, positioning rods and limit columns are fixed on the lower side of the stamping table, a side plate is arranged at the concave part on the side of the stamping table, a top plate is fixed on the upper side of the side plate, and a damping member is arranged between the top plate and the side of the stamping table.

[0007] Preferably, a guide rod and a hydraulic seat are arranged between the top plate and the corner of the stamping template, and the guide rod and the hydraulic seat are on the same side.

[0008] Preferably, support templates are fixedly arranged at equal intervals at the bottom of the stamping template, and a bottom plate is fixedly arranged at the bottom of the support templates.

[0009] Preferably, an inclined plate is arranged in the gap of the support template, and the inclined plate is located below the discharge port formed in the middle of the stamping template.

[0010] Preferably, the positioning rod abuts against the upper side of the stamping workpiece, and the stamping workpiece is located between the upper sides of the stamping table and the stamping die core.

[0011] Preferably, the limit post is matched with the limit hole formed in the edge of the stamping die core.

[0012] Preferably, a hole matched with the stamping head is arranged in the middle of the stamping die core, and the hole arranged in the middle of the stamping die core is located directly above the discharge port.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the installation position of the side plate and the stamping table determines the distance between the top plate and the stamping table, and further determines the damping value of the damping member in the initial state, adjusts the buffering force of the damping member on the top plate. Compared with the traditional spring structure, the setting of this damping member not only facilitates the adjustment of the damping value, but also can act on the top plate alone, reducing the stress generated on the top plate and the stamping template during the buffering process, and protecting the mold assembly itself;

[0015] Specifically, during the stamping process, the stamping table stamps the stamping part arranged on the stamping die core, and the reaction force generated by the stamping is transmitted to the damping member. The damping member converts the kinetic energy, reduces the influence on the top plate, thereby improving the relative stability between the top plate and the stamping template. At the same time, the initial damping value of the damping member is affected by the extension length of its output end. Therefore, the change in the position of the side plate relative to the stamping table will cause the distance between the top plate and the stamping table to change, and further adjust the extension length of the damping member to achieve the adjustment of the damping value.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figures 1-4 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a conveniently adjustable mold assembly, including a stamping template 2; a stamping die core 12 and a receiving block 13 are fixed to the middle of the upper side of the stamping template 2, a stamping table 9 is arranged above the stamping die core 12 and the receiving block 13, and a stamping head 14 is fixed to the middle of the stamping table 9, and a positioning rod 16 and a limiting column 15 are fixed to the lower side of the stamping table 9, a side plate 10 is arranged at the side depression of the stamping table 9, a top plate 1 is fixed to the upper side of the side plate 10, and a damping member 11 is arranged between the top plate 1 and the side of the stamping table 9;

[0024] It should be noted that: in the mold assembly involved in the present application, the installation position of the side plate 10 and the stamping table 9 determines the distance between the top plate 1 and the stamping table 9, and further determines the damping value of the damping member 11 in the initial state, and adjusts the buffering force of the damping member 11 on the top plate 1. Compared with the traditional spring structure, the setting of the damping member 11 is not only convenient for adjusting the damping value, but also can act on the top plate 1 alone, reducing the stress on the top plate 1 and the stamping template 2 during the buffering process, and protecting the mold assembly itself. When in use, during the stamping process, The stamping table 9 stamps the stamping parts arranged on the stamping die core 12, and the reaction force generated by the stamping is transmitted to the damping member 11. The damping member 11 converts the kinetic energy to reduce the impact on the top plate 1, thereby improving the relative stability between the top plate 1 and the stamping template 2. At the same time, the initial damping value of the damping member 11 is affected by the extension length of its output end. Therefore, the change of the position of the side plate 10 relative to the stamping table 9 will change the distance between the top plate 1 and the stamping table 9, and then adjust the extension length of the damping member 11 to achieve the adjustment of the damping value.

[0028] It should be noted that: the bottom plate 6 is used for the installation and fixation of the support templates 5, and the support structure composed of the bottom plate 6 and the support templates 5 is used for supporting the stamping template 2. The workpieces falling through the discharge port 8 are caught by the inclined plate 7 and slide down under the action of the impact force, so as to avoid accumulation between the support templates 5 and affecting subsequent discharging.

[0029] Among them, as Figure 3 and Figure 4 shown, the positioning rod 16 abuts against the upper side of the stamping workpiece, and the stamping workpiece is located between the upper sides of the stamping table 9 and the stamping die core 12; the limit post 15 is matched with the limit hole opened at the edge of the stamping die core 12;

[0030] It should be noted that: the positioning rod 16 is used for limiting the stamping workpiece, while the limit post 15 is used for keeping the relative position between the stamping die core 12 and the stamping table 9 fixed.

[0031] A hole matching with the stamping head 14 is arranged in the middle of the stamping die core 12, and the hole arranged in the middle of the stamping die core 12 is directly above the discharge port 8;

[0032] It should be noted that: during the punching process, the stamping head 14 punches out the shape of the hole arranged in the stamping die core 12 for the stamping workpiece, and the punched and dropped workpieces fall through this hole to the discharge port 8.
