Problems solved by technology
[0004] The purpose of the present invention is to solve the existing bolt forming mold. When the bolt head is injection-molded, if the raw material in the injection molding cavity contains air bubbles, it is easy to cause the inside of the molded part to be doped with air bubbles, which reduces the quality of the bolts and does not have the ability to prevent air bubbles. To exclude the functional disadvantages, a bolt forming die is proposed

The invention discloses a bolt forming mold. The bolt forming mold comprises a base, four guide rods are welded to the periphery of the top end of the base, and a connecting plate is welded to the topends of the four guide rods; a lower mold body is installed at the upper end of the base, and an upper mold body is movably connected to the top end of the lower mold body; and a first hydraulic telescopic rod is fixedly connected to the bottom end of the connecting plate, a mounting plate is fixedly connected to the bottom end of the first hydraulic telescopic rod, the mounting plate is fixedlyconnected with the top end of the upper mold body, and a forming cavity is formed between the upper mold body and the lower mold body. According to the bolt forming mold, a supporting plate and the lower mold body can be driven to shake through a vibrator, and when the supporting plate shakes, telescopic outer rods can assist the supporting plate to vibrate at a high frequency through first resetsprings, so that the lower mold body and the upper mold body are stressed to vibrate; and when molding raw materials are poured into the molding cavity, bubbles in the raw materials in the molding cavity can be discharged in a shaking mode, air bubbles are prevented from appearing after the bolt is formed, and the quality of a formed product is improved.
Description
technical field [0001] The invention relates to the technical field of bolt forming die equipment, in particular to a bolt forming die. Background technique [0002] Bolts and screws are the most basic mechanical parts and are widely used in various industries such as automobiles, industrial machinery, and construction. Unlike welding and riveting, the biggest feature of bolts is that they can be easily removed even after tightening, and can be tightened by retightening. In the process of forming and preparing the bolts, the rod body is usually injected into the bolt head, and then the cutting and thread groove operations are performed. [0003] In the process of using the existing bolt forming mold, when the bolt head is injection-molded, if the raw material in the injection molding cavity contains air bubbles, it is easy to cause the inside of the molded part to be mixed with air bubbles, which reduces the quality of the bolts and does not have the ability to prevent air b...
