Full-circle inverted buckle demolding sliding block structure

Abstract

The invention discloses a full-circle inverted buckle demolding sliding block structure, and aims to provide the full-circle inverted buckle demolding sliding block structure which improves the qualified rate of products, is high in reliability degree and comprises a sliding block, a supporting seat and a mold body, and the supporting seat is connected to the inner side of the sliding block and matched with the inner wall of a full-circle inverted buckle. An assembling space is formed between the inner wall of the sliding block and the outer wall of the supporting seat, the mold body comprises a plurality of mold bodies connected in the assembling space in a surrounding mode, the multiple mold bodies are connected in a surrounding mode to form a mold cavity used for injection molding of a full-circle inverted buckle, and the multiple mold bodies are elastically connected relative to the supporting seat. The plurality of mold bodies always have the trend of radial movement; during injection molding, the mold bodies are arranged in the assembling space, and the mold bodies are connected in a surrounding manner to form the mold cavity for injection molding of the full-circle inverted buckle; and when demolding is carried out after injection molding is completed, the mold bodies move in the radial direction relative to the outer wall of the full-circle inverted buckle so that the mold cavity can release the outer wall of the full-circle inverted buckle to complete demolding of the full-circle inverted buckle. The invention relates to the technical field of molds.

Description

technical field [0001] The invention relates to the technical field of molds, and more specifically relates to a structure of a full-circle undercut mold ejection slider. Background technique [0002] The windshield washing pot in the car is used to spray the washing liquid on the windshield, and use the wiper to remove the dust, sand and other dirt on the outer surface of the windshield of the car, so as to provide the driver with a clear vision. To ensure driving safety. [0003] In the prior art, the windshield washing pot usually adopts a plastic integral structure, and is usually provided with a full-circle undercut for connection. [0004] Currently on the market for this type of full-circle undercut, sliders are usually installed on both sides to demould. The mold of this type of structure needs to have enough space on both sides of the undercut to set up sliders, and the sliders on both sides drive the mold to demould, but it is limited The space at the undercut of...

Problems solved by technology

[0004] Currently on the market for this type of full-circle undercut, sliders are usually installed on both sides to demould. The mold of this type of structure needs to have enough space on both sides of the undercut to set up sliders, and the sliders on both sides drive the mold to demould, but it is limited The space at the undercut of the car air duct is small, the sliders are not easy to arrange, the structural design is more complicated, and the cost is higher; and when the mold is demoulded and closed, the mold body driven by multiple sliders is unevenly stressed , resulting in products with unreasonable structural strength distribution, flashes, burrs and other defects in production, and the product qualification rate is greatly reduced
