Description

Technical Field

[0001] This utility model relates to the field of molding dies, and in particular to a continuous molding die for the left side plate of a condenser. Background Technology

[0002] High-speed continuous stamping die refers to a cold stamping die in which a press uses strip-shaped stamping raw material to complete multiple stamping processes simultaneously on a die with several different stations in one stamping stroke. After each stamping stroke, the strip moves a fixed distance once until the product is finished.

[0003] In existing stamping die structures, the stripper plate in the die serves functions such as guiding, pressing, and stripping. The stripper plate 1 forms a pressing groove through a clearance mechanism, which plays a crucial role in the die's operation. During die closing, the stripper plate first presses the strip material through the pressing groove, ensuring the flatness of the strip 2 and the stability of the entire die operation.

[0004] For automotive parts stamping production, single-station dies have a simple structure and low production efficiency, while complex dies have fewer stations, which is not conducive to the stamping and forming of products. Progressive dies, on the other hand, use a press to simultaneously complete multiple stamping processes on a single die using strip-shaped raw materials in one stamping stroke. Each stamping cycle is completed by the die, and the strip moves a fixed distance until the product is finished. Traditional progressive dies for processing the left side panel of a condenser are simply designed based on the shape, resulting in complex and poorly designed dies with high development costs. Furthermore, traditional dies, where the upper and lower dies directly contact each other to stamp the workpiece, suffer from: 1. Cumbersome operation, high labor and time consumption, leading to high costs and low production efficiency; 2. Instable product dimensions due to single-sequence processing. Utility Model Content

[0018] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1, such as Figure 1-5As shown, a continuous forming mold for a left side plate of a condenser includes an upper mold structure, a lower mold structure, a continuous forming mechanism disposed between the upper mold structure and the lower mold structure, a punching component structure disposed between the upper mold structure and the lower mold structure, and a transmission mechanism 31 disposed between the upper mold structure and the lower mold structure.
