Description

Technical Field

[0001] The utility model belongs to the technical field of transfer molds, and in particular relates to a one-out-two-type multi-process transfer mold. Background Art

[0002] Transfer dies are special process equipment used to process materials into parts during cold stamping, and are called cold stamping transfer dies. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. Multi-station stamping transfer dies have multiple stations, and can use a variety of different dies to perform a variety of different process operations on a workpiece. They are accurate and quick to use, can improve the workpiece yield, and increase production, and are very practical.

[0003] Currently, for single-station molds, one-out-two or even one-out-many applications are very common. However, there are certain problems in applying one-out-two to transfer films. For example, the male and female mold systems of the current one-out-two mold are an integrated whole, which is inconvenient when the mold needs to be repaired. For example, when a mold cavity needs to be corrected, both mold cavities often need to be corrected together. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a one-out-two-type multi-process transfer mold, which has the characteristics of easy maintenance and high maintenance efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a one-out, two-type, multi-process transfer mold, comprising a lower mold base and an upper mold base, at least two punch cavities are provided above the lower mold base, a punch is embedded in the punch cavity, a cover plate is connected to the top of the lower mold base, a connecting block is connected to the top of the upper mold base, a die base is connected to the bottom of the upper mold base, two die cavities corresponding to the punch cavities are provided below the die base, and a die is embedded in the die cavity.

[0006] In order to facilitate disassembly and assembly, further, the punch and the cover plate are connected to the lower die base by bolts.

[0007] In order to limit and fix the die, a lower sealing plate is further connected below the die seat by bolts.

[0008] In order to achieve the transition of pressure, make the force of the two concave dies on the product more uniform, and ensure the consistency of product quality, further, a sealing cavity corresponding to the concave die is provided inside the upper die seat. A piston head is embedded inside the sealing cavity. The top of the piston head is connected to the connecting block through a connecting rod.

[0009] In order to limit the installation of the piston head, an upper sealing plate is further connected above the upper die seat.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model has at least two convex mold cavities above the lower mold base, and two concave mold cavities corresponding to the convex mold cavities below the concave mold base. The two convex molds and the two concave molds are designed to be independent. When correction is needed, they can be removed separately, making the maintenance of the mold more convenient and improving the maintenance efficiency.

[0012] 2. The upper die seat of the utility model is provided with a sealing cavity corresponding to the concave die. A piston head is embedded in the sealing cavity, and the upper part of the piston head is connected to the connecting block through a connecting rod. The piston head compresses the air in the sealing cavity to achieve pressure transition, so that the forces of the two concave dies on the product are more uniform, ensuring the consistency of product quality.
