Description
Technical Field
The invention relates to the technical field of detection of injection molding machines, and particularly provides a performance detection device of an injection molding machine.
Background
Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment for producing plastic products of various shapes from thermoplastic or thermosetting plastic by using a plastic molding die, and when in operation, the injection molding machine can heat the plastic to a molten state and apply high pressure to the molten plastic so that the molten plastic is injected to fill the cavity of the injection molding die and then cooled for molding.
The performance of an injection molding machine directly affects the quality of injection molded products and the efficiency of injection molding, wherein the reasonable design and reliable tightness of the injection cavity of the injection molding machine are important performance characteristics of the injection molding machine, the structure of the injection cavity depends on the design and manufacturing process of the injection molding machine, different injection cavity structures can exist in different injection machine models and brands, and therefore, different injection molding machines can have injection cavities with different structures. The straight-line pipe cavity structure is a common injection cavity structure, and consists of a straight-line pipeline, injection materials enter an injection cavity from a charging barrel and are injected into a die through an injection nozzle, so that the straight-line pipe cavity structure is simple in structure, easy to manufacture and maintain and suitable for a medium-small injection molding machine; however, some large-scale or special-requirement injection molding machines may adopt other types of injection cavity structures, such as a curved cavity structure, a multi-cavity injection structure and the like, and the cavity structures can better meet the requirements on pressure, flow and uniformity in the production process, so that the product quality and the production efficiency are improved.
The structure of the injection cavity is determined for a specific injection molding machine, and after the injection molding machine is manufactured and molded, the tightness of the injection cavity is required to be detected. After the injection molding machine is used for a long time, the injection cavity is always in a high-temperature and high-pressure environment in the working process, so that poor sealing conditions possibly occur due to abrasion, aging, loosening and other reasons of the internal structure of the injection cavity; poor sealing of the injection cavity can lead to raw material leakage, machine failure, product quality problems, and the like.
