When the mold is manufactured, many positioning pins need to be installed to fix the relative position between the two parts. The positioning pins are usually sunk into the positioning pin holes on the mold. Since the mold needs to be pulled out frequently during assembly, in order to Remove the parts and make corrections. At the same time, the mold also needs to pull out the positioning pins during maintenance to remove the damaged parts for maintenance. Therefore, the workload of pulling the pins is large. The existing methods are: 1) When installing the pins, The operator uses a self-made long screw that matches the threaded hole of the pin to screw it into the pin, and then aligns the pin hole with a hammer to hit the screw to make the pin snap in, and then screw the screw out by hand. The disadvantage is: on the one hand, the hammer hits the screw It is easy to cause the screw to be damaged or deformed, and it cannot be used normally. On the other hand, it is labor-intensive to remove the screw by hand and may not be able to be removed; 2) When pulling out the pin, the operator will screw the screw into the pin and use force directly or with pliers To pull out a screw, a few companies use a large pin puller to pull it out. The disadvantage is that it is too laborious and time-consuming to pull out by hand or with pliers. Even if a large pin puller is used, the weight of the pin puller itself is large. , it is inconvenient to use.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (10), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the deformation. effect.

Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. It is used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other industries, in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments And supplies, etc., you can see all kinds of fasteners, which are widely used mechanical basic parts. In the fields of listed rails, construction machinery, etc., due to the harsh application environment, the requirements for fasteners are more stringent. If the fasteners are loosened, it may lead to serious consequences, resulting in a large amount of property damage, even serious life cost.
