[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] Reference Figure 1 and Figure 2, a spindle powder metallurgy mold that does not require lathing, includes a base plate 1, a panel 2 and a spindle 16. The spindle 16 is made of powder metallurgy injection molding process and is mainly used for mechanical transmission and other aspects. A front mold 3 is provided at the bottom of the panel 2, and a pouring nozzle 4 is provided on the front mold 3. The pouring nozzle 4 is used to inject raw materials so that it can be formed inside the mold. An inclined guide post holder 5 is also provided on the inner side of the front mold 3, and a front mold core 6 is provided at the bottom of the front mold 3 and on one side of the inclined guide post holder 5. A slider seat 7 and an insert fixing block 8 are also provided on one side of the inclined guide post holder 5, which cooperate with each other to limit the inclined guide post, so as to facilitate the positioning of the mold core. An upper mold core 9 is also provided on the other side of the bottom of the front mold 3. A square iron block 10 is fixedly connected to the top of the base plate 1, and a rear mold 11 is fixedly connected to the top of the square iron block 10. Between the base plate 1 and the rear mold 11 An ejector base 12 and an ejector push plate 13 are also provided, which are used to connect the ejector, and the formed main shaft 16 is pushed out of the mold cavity by the ejector to realize rapid injection molding. A rear mold core 14 is provided on the rear mold 11, and a lower mold core 15 is connected to one side of the rear mold core 14. The grooves between the front mold core 6, the upper mold core 9, the rear mold core 14 and the lower mold core 15 form a mold cavity for molding the main shaft 16, so that the main shaft 16 can be molded therein. A channel for water flow is also provided inside the front mold core 6, the upper mold core 9, the rear mold core 14 and the lower mold core 15, and its function is to quickly cool the molded product and increase its molding efficiency. An axis end molding structure 17 is also clamped in the mold cavity hole groove of the lower mold core 15, which is used to mold the end of the main shaft 16. Different axis end molding structures 17 can be replaced according to the main shaft 16 with different requirements.

[0025] Further, refer to Figure 4 The shaft end forming structure 17 includes a main body 171, and a shaft end groove forming part 172 is fixedly connected to one end of the main body 171, which is used for forming the end hole groove of the main shaft 16. It can have different shapes, so that the end of the main shaft 16 can form different holes and grooves to meet the needs of use.

[0026] Furthermore, a clamping portion 173 is provided on the main body 171, and a positioning portion 174 is fixedly connected to one side of the main body 171. The shaft end molding structure 17 is clamped inside the mold core through the clamping portion 173 and the positioning portion 174, thereby increasing the use effect of the mold.

[0027] Furthermore, the shaft end groove forming portion 172 is in the shape of a hexagonal prism or an octagonal prism.

[0028] The implementation principle of this embodiment is as follows: the metallurgical powder is heated and melted by an external device, and then input into the mold cavity from the nozzle 4 through a pipeline, and then waited for it to cool and form. During the forming process, cooling water can be injected through the channel to achieve rapid cooling of the main shaft 16 after forming. After the forming is completed, the front mold 3, the front mold core 6 and the upper mold core 9 are moved upward, and then the main shaft 16 is ejected from the mold cavity by the ejector, thereby realizing the injection molding of the main shaft 16.
