Description

Technical Field

[0001] The invention belongs to the technical field of metal molds, and in particular relates to a stamping mold for casting metal products and a use method thereof. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] The stamping die, also known as the cold die, forces the metal parts in the die to change their shape according to its specific shape combined with the force of the stamping machine, so that the metal parts are rapidly deformed under the impact of the die shape and the force of the stamping machine, thereby completing the shape change of the metal parts. The stamping die can then rely on its own specific shape to determine the shape of the metal parts after stamping, thereby improving the stamping shape stability of the metal parts.

[0004] The existing stamping dies mainly have the following defects:

[0005] 1. Environmental impact: The noise and vibration generated during the stamping process not only affect the working environment, but also have an adverse effect on the health of the operators;

[0006] 2. Influence of thermal stability: The stamping die will generate high temperature during operation, which will affect the thermal stability of the material, thereby affecting the processing accuracy and surface quality of the die;

[0007] 3. Toughness influence: The mold material is prone to brittle fracture under impact load, and the overall service life of the mold cannot be guaranteed;

[0008] 4. Impact of flexibility: In the stamping process, different molds are required. During use, there are stamping molds and shaping molds. During use, they must be selected and used according to needs, and the overall flexibility cannot be guaranteed.

[0009] Therefore, a new stamping die is needed to solve the above problems. Summary of the invention

[0010] The purpose of the present invention is to reduce the vibration of the upper template during the stamping process by using a buffer mechanism, ensure buffering during use, improve the overall toughness of the mold, and prevent brittle fracture under impact load. In addition, the mold structure is reasonably designed, the relative positions of the various components are accurate, and it is easy to install and debug. At the same time, the vibration of the upper template during stamping is offset by the shock-absorbing holes to achieve the use effect. Through the coordinated use of the silencer and the buffer mechanism, the buffer mechanism reduces the sound during the stamping process. At the same time, the silencer absorbs the noise generated by the collision between the upper template and the lower template during the stamping process, avoiding noise and vibration affecting the working environment and causing adverse effects on the health of the operator. The silencer changes the propagation path of the sound, causing the sound to produce reflection, refraction and other phenomena during the propagation process, resulting in the gradual attenuation of the sound energy. In addition, the flow resistance of the fluid is increased inside the silencer mechanism, so that part of the sound energy is converted into heat energy and consumed, thereby completing the silencer. Through the coordinated use of heat dissipation teeth and heat dissipation holes, the heat dissipation teeth are opened on the limit sleeve at the bottom of the upper template, so as to increase the contact area between the upper template as a whole and the outside, so that the high temperature generated by the stamping of the upper template during stamping can be quickly dissipated, thereby preventing the stamping mold from being affected by the high temperature of stamping during the working process, ensuring the overall thermal expansion coefficient and thermal conductivity of the mold, and improving the processing accuracy and surface quality of the mold. In addition, the limit sleeve corresponds to the lower template to ensure the stability of the upper template during stamping. Through the use of the docking mechanism, the positioning studs, positioning grooves and positioning screw holes cooperate with each other to ensure the connection between the upper template and the lower template, so that different types of upper templates can be stably installed, thereby improving the applicability and flexibility during use.

8. A method for using a stamping die for casting a metal product, characterized in that: A stamping die for casting a metal product according to any one of claims 1 to 7 is used, comprising the following steps: S1. Installing the template: After installing the lower template (1) at the punching position, select the type of upper template (8) to be punched and dock it on the lower template (1). During the installation process, multiple docking sleeves (7) are docked with multiple docking holes (16) to connect the docking sleeves (7) with the docking magnetic columns (15) inside them to complete the movable connection. In addition, the positioning studs (31) are installed in the positioning screw holes (32) so that the positioning studs (31) are docked in the positioning slide grooves (30) to ensure the stability of the upper template (8); S2, stamping buffer: during the stamping process, the buffer diagonal support rod (5) and the buffer diagonal pressure rod (10) cooperate with each other, and the plurality of buffer damping rods (3) and the top buffer spring (4) in the lower template (1) cooperate with each other to complete the shock absorption of pressing the upper template (8).
