[0006] The utility model provides a forming die for a lock - preventing bolt to solve the problems that although the chamfer facilitates demolding, manual demolding is still required, which is time - consuming and laborious, and only a single lock - preventing bolt can be manufactured and formed, resulting in a low output.

[0007] 2. Technical solutions:

[0008] To achieve the above object, the technical solution provided by the present utility model is: a forming die for a lock - preventing bolt, including a supporting bottom plate. On the upper surface of the supporting bottom plate, there is a lower die fixing plate. On the upper surface of the lower die fixing plate, a lower die box body is fixedly connected. On the upper end surface of the lower die box body, there are several screw forming grooves. Around the screw forming grooves, positioning inserts are arranged on the surface of the lower die box body. Above the lower die box body, there is an upper die cover. On the upper end surface of the upper die cover, there is a filling hole.

[0009] Furthermore, the upper die cover is installed above the lower die box body through the lower die fixing plate and forms a lifting structure above the lower die box body through the lower die fixing plate.

[0010] Furthermore, the lower die fixing plate includes a load - bearing plate. On both side surfaces of the load - bearing plate, there are tensioning grooves. Below both sides of the load - bearing plate, there are "U" - shaped tensioning rods. Above both sides of the load - bearing plate and on the surface of both sides of the lower die box body, telescopic oil cylinders are fixedly connected. On the upper end surface of the tensioning grooves, telescopic sliding sleeves are fixedly connected. On the upper end surface of the "U" - shaped tensioning rod, there is a top - cover insert block.

[0011] Furthermore, the telescopic oil cylinder is fixedly connected to the middle of the lower end of the "U" - shaped tensioning rod. And the "U" - shaped tensioning rod forms a lifting structure on the surface of the tensioning groove through the telescopic oil cylinder. The top - cover insert block at the top of the "U" - shaped tensioning rod forms a lifting structure above the lower die box body through the telescopic oil cylinder. The upper die cover is installed above the die box body through the top - cover insert block.

[0012] Furthermore, the upper die cover includes a fitting bottom cover. Inside the fitting bottom cover, there are several alignment grooves. Above the alignment grooves, there are one - way flaps. Above the fitting bottom cover, a cleaning top cover is installed. On the upper end surface of the cleaning top cover, there is an installation screw rod. On one side of the fitting bottom cover and the cleaning top cover, there is a blade base. On the surface of the blade base, a transmission rack is movably connected. At the lower end of the transmission rack, there is a swinging blade. On one side of the installation screw rod and on the upper end surface of the cleaning top cover, there is a meshing connection with a transmission end.

On the lower end surface of the fitting bottom cover, there is a positioning groove that is fitted and connected with the positioning insert. The alignment grooves are perpendicular in position and the same in number as the screw forming grooves.

[0014] 3. Beneficial effects:

[0015] The utility model is reasonably designed. When performing bolt forming operations, the telescopic oil cylinder is started to push the "U"-shaped tension rod downward. The top cover block at the top of the "U"-shaped tension rod drives the upper mold cover downward. At the same time, the positioning slot and positioning plug at the lower end of the bottom cover are used to complete the mold closing of the lower mold fixing plate and the upper mold cover. The inside of the bottom cover is filled with material through the filling hole on the upper surface of the upper mold cover, so that the material in the alignment slot is filled. The material is continuously pressurized through the filling hole, and the fluid material enters the screw forming slot through the one-way flap, completing the forming of the anti-loosening bolt. The production of multiple bolts is realized through a number of alignment slots and screw forming slots, improving the production efficiency.

[0016] When the material in the screw forming slot cools and forms, the telescopic oil cylinder is started to drive the "U"-shaped tension rod upward, driving the entire upper mold cover upward. Thus, the cooled material in the alignment slot drives the formed bolt in the screw forming slot to move upward together. When the bolt is completely demolded from the screw forming slot, the driving end drives the driving rack to rotate, and then drives the swing blade below it to move downward under the bottom cover, cutting off the formed anti-loosening bolt from below the alignment slot, achieving the purpose of avoiding manual demolding.
