The lower module and the lower mold base are connected by counterbore bolts.

When forging through this die, the pre-forged blank is placed in the lower module, the upper and lower modules are clamped, the punch is punched downward, and the shape of the cavity and straight groove is punched out, and the pin hole of the socket is punched out at the same time. When parting the mold, the upper and lower modules are separated by the spring between the guide post and the guide sleeve, and the blank can be taken out. The upper and lower modules and punches can be replaced according to different socket products, and the pin holes of W-shaped or R-shaped pin holes can also be punched out by punches of corresponding shapes. Both W-shaped and R-shaped cap sockets can be forged through this mold, which avoids casting defects, and at the same time reduces the defects of large margins and complicated procedures in traditional processing methods, improves efficiency and reduces costs.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 4, a forging molding die for cap socket metal accessories for composite insulators includes an upper template 1 and a lower mold base 7, a punch 3 passes through the upper template 1, and an upper module 2 is connected to the upper template 1. The lower mold base 7 is connected with the lower module 6, the upper module 2 and the lower module 6 are provided with mold cavities, the upper module 2 is connected with the guide sleeve 4, the lower mold base 7 is connected with the guide pillar 5, and the guide sleeve 4 is set Outside the guide post 5 , the guide post 5 is covered with a first spring 8 , the upper end of the first spring 8 is arranged on the bottom of the guide sleeve 4 , and the lower part of the first spring 8 is arranged on the upper part of the lower mold base 7 .

In the utility model, the guide sleeve 4 can slide up and down along the guide post 5. When forging, the pre-forged blank is placed in the lower module, the upper module 2 moves downward, and the upper and lower modules are closed. The downward motion punches the pocket and pin hole in one pass. The shape of the pre-forged blank is slightly smaller than the size of the die cavity, and the punch 3 punches downwards, so that the blank becomes larger and fills the cavity, and at the same time punches out the pin holes in the cavity. When parting the mold, under the action of the restoring force of the first spring 8, the upper and lower modules are separated, and the workpieces taken out are shown in Figures 3 and 4.

Preferably, the punch 3 is connected to the upper connecting rod 9, the upper connecting rod 9 is arranged in the spacer sleeve 10, the spacer sleeve 10 is connected to the upper template 1, the spacer sleeve 10 is connected to the upper connecting plate 11, and the upper connecting plate 11 A limit column 12 is arranged in the groove at the bottom, and the lower end of the limit column 12 is arranged in the groove of the upper template 1 , and a second spring 13 is provided outside the limit column 12 .

At this time, the movement of the punch 3 and the upper module 2 is separated up and down. The upper connecting rod 9 is driven by the force to drive the punch 3 to move up and down. The template 1 moves downward, and the upper template drives the upper module 2 to move downward. When the force on the upper connecting plate 11 is removed, the upper connecting plate 11 returns to its position under the action of the second spring 13 . In the utility model, the first spring and the second spring are arranged at the same time, so that the upper and lower modules receive a buffer force when they are clamped or parted, which can prolong the service life of the entire mold and prevent deformation of the mold.

In this application, the lower module 6 and the lower mold base 7 are connected by counterbore bolts.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
