Description

Injection molding machine nozzle head device Technical Field The utility model belongs to the technical field of injection molding, and particularly relates to a nozzle head device of an injection molding machine. Background An injection molding machine is a device widely used in the plastic processing industry for heating and melting plastic particles and then injecting the melted plastic particles into a mold for molding. The nozzle tip is one of the key components of an injection molding machine and functions to direct molten plastic from the barrel of the injection molding machine to the gate of the mold. In the prior art, since the nozzle head works at high temperature and high pressure, the surface of the nozzle head is easy to wear or damage, frequent replacement is needed, the traditional nozzle head is usually fixed through threads, and tools are needed to be used for disassembly and assembly during replacement, so that the operation is complex and time-consuming. To this end, the utility model provides a nozzle head device of an injection molding machine. Disclosure of utility model In order to make up for the defects of the prior art and solve the problems that the surface of the nozzle head is easy to wear or damage and needs to be frequently replaced due to the fact that the nozzle head works at high temperature and high pressure, the traditional nozzle head is usually fixed through threads, and the nozzle head needs to be detached and installed by using tools during replacement, and the operation is complex and time-consuming. The technical scheme adopted by the utility model for solving the technical problems is that the nozzle head device of the injection molding machine comprises a nozzle body and an injection molding pipe, wherein a connecting mechanism is arranged on the nozzle body and the injection molding pipe, and the connecting mechanism comprises: The fixing assembly comprises a fixing shell connected with the nozzle body in a sliding sleeve manner, a group of clamping holes are formed in the fixing shell, a group of fixing blocks are fixedly connected to the injection molding pipe, clamping grooves are formed in the side walls of the fixing blocks, and a clamping assembly for clamping is arranged on the fixing shell; And the fastening component is arranged on the fixed shell and used for fastening the nozzle body.
