Description

Technical Field

[0001] The invention relates to the technical field of injection molding devices, in particular to an injection molding device for producing automobile interior plastic parts which is easy to demould. Background Art

[0002] Automotive interior refers to the assembly of various parts installed inside the car, including the dashboard, door panels, center console, seat guards, pillar trims, glove boxes, etc. These parts are not only decorative elements of the car's interior space, but also shoulder important responsibilities such as functional support, human-computer interaction, and safety protection. Their materials, structures and performance are directly related to the vehicle's comfort, safety and user experience. Since automotive interior parts need to meet complex styling designs (such as curved surface transitions, concave and convex textures, etc.), lightweight requirements (to reduce vehicle energy consumption) and diverse performance indicators (such as temperature resistance, aging resistance, environmental protection, etc.), injection molding machines can accurately replicate complex cavities through molds and form parts with three-dimensional surfaces and fine structures in one go, which can meet the automotive manufacturing industry's requirements for component consistency and large-scale production. However, when the injection molding machine changes the color material, in order to prevent the residual color material from affecting the production quality of the new color plastic parts, the operator needs to clean the inner wall of the discharge barrel. However, due to the high position of the discharge barrel, the operator often needs to operate at a higher position, which not only leads to lower safety of the cleaning process, but also makes the cleaning efficiency low; at the same time, when the mold is hot, the ejector pin is easily expanded by heat, which leads to a smaller gap with the mating parts, increased friction resistance, and even jamming. The lubrication method of the ejector pin mostly relies on manual regular application, which is not only time-consuming and labor-intensive, but also has problems such as untimely and uneven application, affecting the smooth movement of the ejector pin; in addition, after the barrel is cleaned, the screw will be cleaned by clearing the material, and the material after clearing is directly sprayed onto the equipment, requiring the operator to use tools for secondary cleaning, which not only increases the amount of manual labor, but may also cause pollution and damage to the equipment due to untimely cleaning.
