Description

Technical Field

[0001] The utility model belongs to the field of production molds and relates to a production mold for processing a heat sink of an IGBT. Background Art

[0002] The molds used to produce IGBT heat sinks are made from high-strength steel, such as H13 steel, which offers excellent wear and heat resistance. Their primary function is to secure the other components of the upper mold and, through connections to the press, evenly transmit the press pressure to the working portion of the mold. Lifting holes are typically provided on the upper mold base to facilitate mold installation and handling.

[0003] However, some existing molds do not fully consider the safety protection of operators during design, and lack necessary guardrails, protective covers and other devices. The guardrails are operated manually, which is time-consuming, labor-intensive and inefficient. During the opening and closing process of the mold, the operator's limbs may accidentally enter the movement area of ​​the mold, causing serious pinching accidents and triggering safety accidents. Utility Model Content

[0004] The purpose of the utility model is to provide a production mold for processing a heat sink for IGBT with a higher safety factor in view of the above problems existing in the prior art.

[0007] In the above-mentioned production mold for processing the heat sink of IGBT, the lower ends of the two spring members are fixedly connected with a connecting transverse plate, and the connecting transverse plate is fixedly connected to the two vertical connecting rollers.

[0008] In the above-mentioned production mold for processing the heat sink of IGBT, the inner end of the connected horizontal plate and the outer end of the extended inner horizontal rod are provided with a plurality of mutually connected positioning inner holes, and the plurality of corresponding positioning inner holes are arranged at equal distances from top to bottom.

[0009] In the above-mentioned production mold for processing the heat sink of IGBT, a latch anti-slip cross bar is inserted between the multiple horizontal positioning inner holes, and the outer side wall of the limiting guide pressing roller is fixedly connected with a wear-resistant coating.

[0010] In the above-mentioned production mold for processing the heat sink of IGBT, the lower end of the extended inner cross bar is fixedly connected to a strip-shaped laser emitter, and the front and rear strip-shaped laser emitters cooperate with each other.

Regardless of whether the stamping speed of the production mold assembly is fast or slow, it can provide real-time protection without manual adjustment, saving time and effort and high efficiency. During high-speed production, it can keep up with the rapid movement of the mold to ensure the safety of the operator. It can also play a protective role in the slow debugging or trial mold stage, and when the follow-up sliding inner plate moves down with the stamping upper mold plate, the U-shaped block under the linkage inner rod can be docked with the lower groove mouth. When the U-shaped block is successfully docked with the lower groove mouth, the spring inner part can be smoothly compressed to make the contact sensor and the upper inner wall of the upper inner groove contact each other. The controller that receives the contact instruction can now start the production mold assembly to successfully run, making the safety factor of the production mold assembly higher.
