Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding protective cover and an injection molding machine. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. Among them, horizontal injection molding machines are usually equipped with protective covers to prevent external dust from affecting the machine.

[0003] For example, the protection mechanism of a horizontal injection molding machine with the authorization announcement number CN218196553U protects different positions of the injection molding machine by setting the first, second and third protective shells respectively, and the protective shells are connected to the injection molding machine through the flower girl fixed on the base of the injection molding machine. However, only the second protective shell needs to be opened from time to time. The first and third protective shells are connected to the injection molding machine through the slide rail, which not only increases the cost of the slide rail part, but also the first and third protective shells are not stable enough. The existing injection molding machine also fixes the first and third protective shells by bolts, but the bolt fixing operation is cumbersome and time-consuming. When inspecting the internal components of the first and third protective shells, it takes a long time to disassemble and install the first and third protective shells. For this reason, a protective cover for injection molding and an injection molding machine are proposed for improvement. Utility Model Content
