[0023] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0024] The embodiment of the present invention relates to a slider structure for forming a concave inner cavity of a cylinder body, such as Figure 1 As shown in FIG. 6 , the product comprises a main support 1, a slide block 2 and a forming block 7. There are two main supports 1, which are symmetrically arranged front to back. Slide blocks 2 are installed on the inner sides of the two main supports 1. A slider 6 is installed between the slide blocks 2 for transverse sliding. A product cavity 9 is arranged on the left side of the slider 6. A forming block 7 is installed on the side of the slider 6 close to the product cavity 9. An inner cavity middle forming block 8 inserted into the product cavity 9 is arranged at one end of the forming block 7 close to the product cavity 9. Two inclined rods 5 are symmetrically installed front to back in the middle of the slider 6. The end of the inclined rod 5 close to the product cavity 9 is inclined toward the center line of the product cavity 9. The end of the inclined rod 5 close to the product cavity is inserted into the product cavity 9 and fits with the front and rear sides of the inner cavity middle forming block 8. The end is arranged with an outer protrusion 12 corresponding to the front and rear recessed side walls 11 of the product cavity 9.

[0025] The above technical structure is mainly designed to realize the molding of the recessed part inside the cylinder body. The specific movement process of this structure when demolding after the product is formed is as follows: first, start the cylinder 3, and the main shaft of the cylinder 3 pulls the linkage plate 4 to move to the right, and the linkage plate 4 pulls the slider 6 and the molding block 7, so that the middle molding block 8 inserted into the inner cavity of the product cavity 9 is separated from the inner cavity of the cylinder body. Then, under the action of the slider 6 and the molding block 7, the two inclined rods 5 shrink and close, and the outer protrusion 12 on the inclined rod 5 is separated from the front and rear recessed side walls 11 on the inner wall of the cylinder body. When the inclined rod 5 shrinks to the limit position, one end of the outer protrusion 12 of the inclined rod 5 can be removed from the opening of the cylinder body to achieve demolding.

[0026] Preferably, a linkage plate 4 connected to the slider 6 is installed below the slider 6, and a cylinder 3 connected to the linkage plate 4 with a push rod is installed between the other end of the main bracket 1 through a longitudinal panel. The cylinder 3 drives the slider 6 to slide through the linkage plate 4, so that a large amount of space can be left between the cylinder main shaft and the slider 6 to help the diagonal rod 5 to close and pull out.

[0027] like Figure 4As shown, preferably, a transmission inclined hole 13 matching the inclined rod 5 is arranged in the forming block 7, and the transmission inclined hole 13 effectively limits and transmits the inclined rod 5. When the forming block 7 moves outward with the slider 6, the forming block 7 and the inclined rod 5 move relative to each other. Under the action of the transmission inclined hole 13, the two inclined rods 5 can move in the direction between the two to achieve separation from the sunken part of the cylinder body.

[0028] like Figure 4 as well as Figure 6 As shown, preferably, the slider 6 is provided with an anti-interference oblique hole 14 corresponding to the oblique rod 5. In the actual working process, the two oblique rods 5 will interfere with the slider 6 during the withdrawal process, so that the oblique rod 5 is easily squeezed and deformed by the slider 6. In order to ensure the use effect of the slider structure, the slider 6 is provided with an anti-interference oblique hole 14. The volume of the anti-interference oblique hole 14 is larger than the volume of the oblique rod 5 located on the slider 6, so that the part of the oblique rod 5 is in a suspended state, avoiding the interference of the oblique rod 5 with the slider 6 when it is pulled out.

[0029] Preferably, the slider 6 is symmetrically provided with extrusion pins 10 at one end close to the product cavity 9, and the extrusion pins 10 pass through the forming block 7 and are inserted into the end of the product cavity 9. During the production process, the thickness of the end of the cylinder body is very small, and the exhaust of this part is very uneven, resulting in poor structural quality of this part and easy formation of shrinkage holes. In order to solve this problem, two extrusion pins 10 are installed on the slider 6. Before filling, the extrusion pins will be partially in place, and then the aluminum liquid will be filled. When the filling pressure and the amount of aluminum liquid remain unchanged, the cavity volume at the end of the cylinder body is reduced, so that the product density of this part is increased, thereby solving the problem of easy formation of shrinkage holes in this part.

[0030] like Figure 5 As shown, preferably, a slide groove 16 is arranged at the upper and lower end edges of the opposite side of the oblique rod 5, and a guide block 15 corresponding to the two oblique rods 5 is installed on the side where the slider 6 is connected to the forming block 7, and the guide block 15 is embedded in the forming block 7 and docked with the slide groove 16. Since the diameter of the oblique rod 5 is small and the length is long, the pressure bearing capacity of the oblique rod 5 will become smaller. It is well known that when the die-casting mold is working, the mold cavity will be filled with aluminum liquid, and the pressure in the mold will be increased, so that the force on the oblique rod 5 during operation increases. In order to ensure that the oblique rod 5 will not be offset and deformed, a slide groove 16 is arranged at the upper and lower end edges of the opposite side of the oblique rod 5, and a guide block 15 corresponding to the two oblique rods 5 is installed on the side where the slider 6 is connected to the forming block 7, and the guide block 15 is embedded in the forming block 7 and docked with the slide groove 16. The guide block 15 realizes the guiding function and plays a protective positioning role for the oblique rod 5.

[0031] Preferably, a cooling plate 17 is installed under the linkage plate 4, and the cooling pipeline in the cooling plate 17 is connected with the cooling pipeline in the forming block 7. Through the cooling plate 17 and the cooling pipeline in the forming block 7, the cylinder end and the inner cavity can be cooled quickly, thereby improving the product quality of this part and improving production efficiency.
