[0029] The molding mechanism 1 includes a molding mold 101. The inner wall of the molding mold 101 has a molding groove 102. A fixing block 103 is fixedly connected to the inner wall of the molding mold 101. A sliding shaft 104 is slidably connected to the inner wall of the fixing block 103. A spring 105 is sleeved on the surface of the sliding shaft 104. A sliding bracket 106 is fixedly connected to one side of the sliding shaft 104. A slider 107 is slidably connected to the inner wall of the molding groove 102. A limit bracket 108 is fixedly connected to the surface of the slider 107. A cylinder 109 is fixedly connected to the lower end of the slider 107. The design of using two sliding brackets 106 to move on the inner wall of the molding mold 101 and the cylinder 109 to drive the slider 107 to rise and fall at the lower end of the sliding brackets 106 achieves the purpose of protecting the cylinder 109 while extruding the molded bolt, preventing the bolt from damaging the slider 107 or the cylinder 109 during extrusion molding, and making the device more convenient to use.

[0030] The surface of the sliding bracket 106 is slidably connected to the inner wall of the molding die 101, and the spring 105 is located between the fixed block 103 and the sliding bracket 106.

[0031] The machine body 2 includes a protective shell 201. A support frame 202 is fixedly connected to the inner wall of the protective shell 201. A protective top plate 203 is fixedly connected to the upper end of the protective shell 201. A hydraulic rod 204 is fixedly connected to the lower end of the protective top plate 203. A pressure frame 205 is fixedly connected to the output end of the hydraulic rod 204. The design of using the protective shell 201 to protect the device and the pressure frame 205 to compress the material makes the subsequent material compression work more stable and safe, and improves the practicality of the device.

[0032] The upper end of the support frame 202 is fixedly connected to the lower end of the forming mold 101, and the inner wall of the support frame 202 is fixedly connected to the lower end of the cylinder 109.

[0033] The support mechanism 3 includes a first support plate 301, a shock absorber 302 is fixedly connected to the upper end of the first support plate 301, and a second support plate 303 is fixedly connected to the upper end of the shock absorber 302.

[0035] The pressure frame 205 is located at the upper end of the forming groove 102.

[0036] The implementation principle of the novel bolt forming die in the embodiment of the application is as follows: when the device is used, the heated material is first placed in the forming notch 102, then the hydraulic rod 204 at the lower end of the protective top plate 203 is started to be elongated, so as to drive the pressure frame 205 to be pressed downward, thereby pressing the sliding support 106 at the lower end to extrude the material, so that the material is attached to the inner wall of the forming notch 102, so that the forming work of the bolt is completed, the protective shell 201 is used to provide protection for the work of the device and the design that the pressure frame 205 is lowered to extrude the material, so that the subsequent extrusion work of the material is more stable and safe, and the practicability of the device is improved. After the bolt is extruded and formed, the cylinder 109 is started to be raised, and the slider 107 is driven to be raised at the same time. At this time, after the slider 107 contacts the inclined surface of the sliding support 106, the sliding support 106 moves to both sides due to the thrust of the slider 107, and the sliding shaft 104 is driven to retract into the fixed block 103. After the two sliding supports 106 are separated, the slider 107 extrudes the bolt at the upper end of the sliding support 106, so that the upper end of the bolt is separated from the inner wall of the forming notch 102. At the same time, the cylinder 109 on the surface of the slider 107 provides limiting for the position of the slider 107, so as to prevent the slider 107 from moving to the upper end of the sliding support 106 and causing the slider 107 to be unable to be retracted. In this way, the bolt can be conveniently taken out subsequently. The design that the two sliding supports 106 move on the inner wall of the forming die 101 and the cylinder 109 drives the slider 107 to ascend and descend at the lower end of the sliding support 106 achieves the purpose that the bolt is extruded after being formed and the cylinder 109 is protected at the same time, so as to prevent the bolt from damaging the slider 107 or the cylinder 109 during extrusion and forming, and make the use of the device more convenient.
