Description

Plastic screw processing device Technical Field The application relates to the technical field of plastic fastener processing, in particular to a plastic screw processing device. Background The plastic screw is a fastener formed by compounding a metal screw body and an injection molded nylon end. The nylon end is wrapped on the head or the rod of the screw through an injection molding process, so that the screw has the mechanical strength of a metal screw and the insulation, corrosion resistance and buffering performance of a nylon material. The plastic screw is widely applied to the scenes of electronic equipment, automobile parts, medical appliances and the like with higher requirements on light weight, anti-loosening or insulation. In the related art, the nylon sleeve injection molding process of the plastic screw is generally realized by adopting a special injection mold. The upper template of the injection molding machine is fixed below the injection molding head and used for guiding nylon melt to flow into the mold cavity, the lower template is arranged on the table top of the injection molding machine and provided with a plurality of screw positioning grooves for inserting metal screws to be processed in batches. The lower die plate is connected with the table top of the injection molding machine through the lower die holder, and the stability of the die in the injection molding process is ensured through mechanical locking structure adaptation between the die holder and the die plate. After injection molding, the plastic screw is formed into a complete structure by wrapping the screw end with a nylon sleeve. For the related technology, the specification of the die holder and the template is single, and only the screw with a specific length can be matched. When the screws with different lengths are required to be processed, the whole set of lower templates and the die holder are required to be stopped and replaced, so that equipment is frequently adjusted, and manual intervention and stopping time are increased. For example, M4 and M6 screws are switched for production, the original die holder is required to be disassembled and a special die holder with a corresponding length is required to be installed, the operation is complex, and the injection molding precision is easy to be reduced due to the alignment deviation. Disclosure of utility model In order to solve the problem that corresponding templates and die holders need to be replaced when screws with different specifications are subjected to injection molding, the complicated operation of die replacement is reduced, and the application provides a plastic screw processing device. The application provides a plastic screw processing device which adopts the following technical scheme: The utility model provides a plastics screw processingequipment, includes the mesa of moulding plastics, locates the injection molding machine of moulding plastics mesa, locate the cope match-plate pattern of injection molding machine notes first position department, locate the mesa of moulding plastics and be located the die holder of cope match-plate pattern below and locate the die holder is used for inserting the lower bolster of waiting to mould plastics the screw, the mesa of moulding plastics is equipped with and is used for the lifting mechanism of injection molding machine, the die holder is equipped with the confession the installation spout of lower bolster installation, the die holder along the direction of height seted up with the installation spout is linked together and supplies the high groove that the screw stretches into. Through adopting above-mentioned technical scheme, the lower bolster passes through spout plug-in installation, need not to dismantle the die holder and can switch different specification templates fast, solves the traditional technique and need wholly change the troublesome problem of die holder, and the longitudinal extension in high groove provides the developments for screw length difference and dodges the space, combines the linkage regulation of injection molding aircraft nose height, realizes the accurate parcel different length screw ends of nylon. The lifting mechanism can adjust the relative height of the injection molding machine and the lower template in real time, ensures that the injection depth of the nylon melt is accurately matched with the length of the screw, and avoids the defect of incomplete package or flash caused by height error. The modularized arrangement does not need to store a large number of special die holders and templates, and the development cost and the stock pressure of the die are reduced. Furthermore, a plurality of positioning through grooves which are distributed and are used for inserting screws are vertically formed in the lower die plate, a plurality of lower plate injection grooves which are used for forming a cavity are formed in one side of the lower die plate, which is close to the injec
