Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a four-slide synchronous core-pulling mechanism of an injection mold for an automobile air filter housing. Background Art

[0002] In the injection molding process, in order to mold plastic parts with complex geometric shapes, movable mold cores or other movable mold components are often required to construct these complex structures. However, the current mold system is often inefficient when performing disassembly operations and lacks the necessary convenience and practicality, which undoubtedly increases the production cycle and cost. In addition, the temperature management of the injection mold is a key factor affecting the entire injection molding process. It is not only directly related to the filling performance of the plastic, the accurate shaping of the plastic parts, and the length of the molding cycle, but also has a decisive influence on the quality of the final plastic parts. Since the temperature at different positions in the mold may be different, the temperature detection at a single position cannot fully reflect the temperature condition of the entire mold. Therefore, this measurement method has a large error, which may lead to inconsistency in product quality and defects.

[0003] In this solution, a four-slide synchronous core-pulling mechanism of the automobile air filter housing injection mold is therefore required to improve the above-mentioned problem. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, through the four-slide synchronous core-pulling mechanism of the automobile air filter housing injection mold, after the mold is opened, the switch of the controller is turned on, so that the four lower cylinders pull the sliders to disengage in four directions, and the four ejectors therein will be driven by the ejector plate driving member below to push the entire ejector ring upward, thereby realizing the overall ejection of the injection molded part. After the upper cylinder drives the core block to pull the core, the lower cylinder drives the slider to disengage, and further drives the upper cylinder to move outward as a whole through the connecting member to avoid hindering the ejection of the injection molded part.
