Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

As shown in fig. 1-2, the utility model provides a small-size component precision mold, include: the die comprises an upper die base 2, a lower die base 1, guide columns 3, an upper die 4 and a lower die 5, wherein the upper die base 2 is connected with the lower die base 1 through the guide columns 3. The bottom of the upper die base 2 is provided with an electric slide rail 21, the electric slide rail 21 is slidably connected with a slide rod 22, the bottom of the slide rod 22 is fixedly connected with an upper die plate 23, and the upper die plate 23 is fixedly connected with the upper die 4, so that the upper die 4 can horizontally slide and adjust the position. The bottom of the upper die 4 is provided with a positioning rod 41, and the upper die 4 is internally provided with a radiating pipe 42, so that the production efficiency can be effectively improved. The lower die 5 is arranged on the lower die holder 1, and a positioning groove 51 matched with the positioning rod 41 is arranged on the lower die 5; a limiting plate 11 is arranged on the lower die holder 1, a sliding groove 15 is arranged on the lower die holder 1, a rack 12 matched with the sliding groove 15 is arranged in the sliding groove 15, the rack 12 is fixedly connected with the limiting plate 11, motors 13 enabling the rack 12 to horizontally move are arranged on two sides of the lower die holder 1, the motors 13 are connected with gears 14 located inside the lower die holder 1, and the gears 14 are meshed with the rack 11.

In some embodiments, the bottom of the positioning groove 51 is provided with a cushion 52, which can effectively prevent rigid collision during mold closing and damage to the mold.
