Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a double-slider sequential core-pulling mechanism for a combined sofa chair mold. Background Art

[0002] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying complexity of the structures of plastic molding machines and plastic products, there are also many types and structures of plastic molds. When plastic sofa chairs are injection molded, a core-pulling structure is required to complete the hollow structure of the sofa chair. Due to the large overall structure of the sofa chair, during the injection molding process, the core-pulling structure is easily impacted by the molten material, causing the core-pulling structure to shake and slide, affecting the accuracy of the injection molding, causing the plastic parts to deform, and affecting the quality of the plastic parts. Therefore, it is urgent to design a double-slider sequential core-pulling mechanism for a modular sofa chair mold.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses an injection mold for a plastic sofa chair with an imitation rattan structure [application number: 202322076025.7], which includes a lower template, on which a molding cavity is provided, and two No. 1 arc-shaped core-pulling plates inserted into the molding cavity are symmetrically arranged on the left and right sides of the molding cavity, and a No. 2 arc-shaped core-pulling plate inserted into the molding cavity is provided on the rear side of the molding cavity. Two No. 1 arc-shaped core-pulling plates and one No. 2 arc-shaped core-pulling plate can form cavities on the left and right sides and the rear side of the product. When the product is ejected, the arc-shaped core-pulling structure can drive the No. 2 arc-shaped core-pulling plate to pull the core, and the arc-shaped synchronous core-pulling mechanism can synchronously drive the two No. 1 arc-shaped core-pulling plates to synchronously pull the core.
