Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a continuous stamping die. Background Art

[0002] As we all know, molds are tools used to manufacture parts of specific shapes and sizes. Through mold forming, efficient and low-cost mass production can be achieved. Molds can be divided into various types according to different classification standards. For example, by application, they can be divided into injection molds, die-casting molds, and stamping molds; by structure, they can be divided into single-cavity molds and multi-cavity molds; and by the processing object and processing technology, they can be divided into molds for processing metals, non-metals, and powder metallurgy.

[0003] When using a mold, the pressing plate on the top of the mold is usually used to position the forming table. If multiple continuous stampings are to be performed, precise focusing is required to help the pressing plate stamp the mold forming table to facilitate part molding. If the positioning effect is not accurate enough, it is easy to cause the mold to shift, causing deviations in the multiple molding of the part, which is not conducive to part processing.

[0004] The utility model with application number CN201920319647.9 discloses an anti-drift precision mold, comprising a first mold body and a second mold body, a limiting shaft is installed on the top surface of the first mold body, and a first connecting hole is provided in the center of the limiting shaft, the second mold body is located above the first mold body, and the second mold body and the limiting shaft are interconnected, a limiting groove is provided on the top surface of the limiting shaft, and the limiting groove and the limiting block are interconnected, and the limiting block is provided on the bottom surface of the support shaft, the support shaft is located inside the second mold body, and the support shaft passes through the second mold body. This anti-drift precision mold, when the precision mold needs to be assembled, first fixes the second mold body to the top of the first mold body through the limiting shaft, which facilitates the subsequent fixed installation of the precision mold and avoids the deviation of the precision mold during the installation process.

[0005] This application prevents the mold from shifting by setting a limit block connected to the limit groove. However, during the use of the mold, there is a pressing plate on the top of the mold to press the mold. When the pressing plate is too large, the pressing coverage area is wide. When the mold is stamped multiple times, the mold withstands less pressure and the parts cannot be formed well. If the pressing plate is too small, the mold bears a greater force and is easily damaged during multiple stampings.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] like Figures 1 to 5 As shown, a continuous stamping die includes: a closing component; a forming component for forming parts; and a buffering component for buffering the die during forming.

[0029] As the mold operates, the part is formed through multiple steps: Pre-processed molding material is loaded into the mold cavity. In stamping, the sheet is fed into the mold, which closes, trapping the molding material within the cavity. Under the closing pressure of the mold, the molding material deforms into the desired part shape.

[0030] The closing assembly includes: a closing plate, a mounting hole formed in the closing plate, a positioning plate mounted at the center line of the long side of the bottom of the closing plate, and a positioning rod mounted at the bottom of the closing plate; by placing the mold on the stamping table, the stamping machine presses the closing plate, so that the positioning rod at the bottom of the closing plate moves downward and contacts the forming table, so that the closing plate remains stable during the stamping process; at the same time, the positioning plate separates the parts and positions the center of the mold, so that the positioning plate contacts the forming table, thereby maintaining the stability of the parts on the forming table;

[0031] The cross-section of the positioning rod is circular, and the cross-section diameter of the positioning rod is smaller than the cross-section diameter of the mounting hole. The positioning rods are provided in multiple groups and are of the same length; so that the multiple groups of positioning rods can contact the bottom surface of the mounting hole at the same time during the descent process, fix the forming table, and maintain horizontal contact between the closing plate and the forming table when stamping the parts.

[0032] The forming assembly includes a forming table, a positioning hole opened on the forming table, and a locking column installed on the forming table. Three groups of plug rods are installed on the top of the locking column, and the three groups of plug rods are in a quarter circle. The holes on the closing plate are plugged into the locking column, and the three groups of plug rods are connected to the mounting holes. During the docking process between the locking column and the closing plate, the three groups of plug rods are vertically inserted into the mounting holes, so that the slots in the mounting holes corresponding to the three groups of plug rods are filled, thereby playing an anti-drift role and preventing the forming table and the closing plate from drifting.

[0033] The buffer assembly includes a base, a through hole is opened on the base, and a spring is installed in the through hole, a buffer pad is provided between the base and the forming table, and is plugged into the forming table and the base, the spring is fixedly connected to the buffer pad, and an anti-slip pad is provided at the bottom of the base; during the stamping process of the parts, the buffer pad is provided to prevent the chassis from being deformed due to impact force during the violent stamping process, so as to protect the bottom position of the mold, and the mold has a layered structure, which is easy to assemble and disassemble, and can still be used normally after removing a layer, and can cope with different processing scenarios to improve the applicability of the mold.

[0034] As a supplement: When the mold is continuously stamped, since the mold is a hard object, a spring is required to cushion its bottom during stamping to prevent the mold surface from being damaged due to excessive stamping.

[0035] Working principle:

[0036] By placing the mold on the stamping table, the stamping machine presses the closing plate, so that the positioning rods at the bottom of the closing plate move downward and connect with the forming table, so that the closing plate remains stable during the stamping process. At the same time, the positioning plate separates the parts and positions the center of the mold so that the positioning plate contacts the forming table to maintain the stability of the parts on the forming table, so that multiple groups of positioning rods contact the bottom surface of the mounting hole at the same time during the descent process, and the forming table is fixed to maintain horizontal contact between the closing plate and the forming table when the parts are stamped. The holes on the closing plate are plugged through the locking columns, and the three groups of rods are connected to the mounting holes. During the docking process between the locking columns and the closing plate, the three groups of rods are vertically inserted into the mounting holes, so that the slots in the mounting holes corresponding to the three groups of rods are filled, so as to play an anti-drift role and prevent offset between the forming table and the closing plate.

[0037] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
