Description

Technical Field

[0001] The utility model relates to the technical field of tool manufacturing, in particular to a mold for manufacturing a cutting tool. Background Art

[0002] With the continuous development of modern manufacturing industry, the demand for cutting tools in various fields is growing. Metal ceramics have the advantages of low specific gravity, excellent red hardness, high wear resistance, high chemical stability, etc. They have great application prospects in extreme service environments and can meet the high-speed cutting requirements of difficult-to-process materials such as titanium alloys and high-temperature alloys. However, traditional cutting tool manufacturing methods often have many limitations, such as low demoulding efficiency and difficulty in adapting to the production of tools of different sizes. How to ensure the accurate formation of tool mounting holes and reduce defects such as pores and cracks in the subsequent sintering process has always been an urgent problem to be solved in the industry. At present, the common cutting tool molds on the market have poor versatility and often need to replace different molds for size positioning, which not only increases production costs, but also wastes a lot of disassembly time. Moreover, in the process of tool demoulding, the traditional demoulding method is complicated and inefficient. In the process of stamping, the direct extrusion of metal ceramic powder may cause uneven internal structure, affecting the quality of subsequent tool sintering. The tool after stamping needs to be processed again by secondary drilling and other processing steps, which increases the process steps and reduces production efficiency. Utility Model Content

A timer is provided in the control system of the HG series electric heater, and the heating time can be preset as needed. When the electric heater is started, the timer starts timing. After the preset heating time is reached, the control system automatically cuts off the power supply of the electric heater and stops heating to allow the heat conduction plate to cool down and recover.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The utility model adjusts the position of the module on the heat conducting plate by setting a mold device, a mold plate with a threaded rod connected by a thread, and a rotatably connected module, so as to adapt to the production requirements of cutting tools of different sizes, improve the versatility of the mold, and reduce the cost and time of replacing the mold due to changes in tool size. The setting of the core rod ensures the accurate formation of the cutting tool mounting hole. The design of the heat conducting plate enables the metal ceramic powder to be preheated while being compressed and formed. After the metal ceramic powder is heated, the yield strength of the material will be reduced, which makes it easier for the material to undergo plastic deformation during the stamping process, reducing the required stamping pressure. At the same time, after the powder particles are heated, the molecular thermal motion is intensified, and the friction between the particles is reduced, so that the powder flows more smoothly in the mold, which can ensure that the powder fully fills every corner of the mold and reduces molding defects.

The extrusion spring is compressed and stored in the demolding process. After the tool is taken out, the push handle is released, and the elastic force is automatically released to reset the demolding plate and the slider, so as to prepare for the next stamping work, saving time and labor costs.
