Embodiment Construction

[0010] In the figure, the italic cover core (2) of the main cover (1) and the elliptical sealing chip (3) are injection molded on the mold parting surface (6) of the same oblique line, and the mutual circumferences are close to each other. The eccentric thin-walled connecting strip (4) connects the body, and the center of the elliptical sealing chip (3) is shifted to the radial direction and protrudes 0.5-3 mm into the italic cover core (2). The top of the mold core (5) is the mold parting surface (6) of the oblique ray, which is processed into a concave cavity (7) with a center offset on the parting surface, and the center of the mold core (5) has a The incoming and outgoing cooling channels and mold cores (5) are respectively fixed on the fixed plates of the upper die (injection) and the lower die (ejection).

Abstract

Dislocation bottle cap and moulds core relate to injection molding technology of bottle cap of barreled drinking water. Known bottle cap has following disadvantages: complicated manufacturing technique, big seal difficulty, high cost, being difficult for loading, cover core is hard to be bursting, the drinking machine is delicate, and motion cycle period of the moulds is long, productivity effect and rate of finished products are affected. The dislocation bottle cap and moulds core can reduce manufacturing technique as well as improve sealing reliability, and the drinking machine can be loaded easily. For the reason of fixing the moulds core at lower mould, injection moulding speed is obviously enhanced, reject rate is greatly reduced, and safety and stability of the moulds are improved.

Description

Technical field: [0001] The invention relates to a plastic bucket, that is, a lid for sealing a water purification bottle, specifically a bucket lid for barreled drinking water. Background technique: [0002] Similar bottle caps and moulds are not found in the existing commercially available and publicly used bottle caps and the patent application documents and publications before the application date. Among them, the applicant stated in the Chinese patent application documents of application numbers 01205819.x, 02201762.3, 03202849.0, and 200410002677.5 that the local structures are similar, but the overall effect still has many defects. Although a kind of bottle cap disclosed in the patent document of the patent No. 0021796.8 has overcome some defects of previous bottle caps, it has also brought new unfavorable factors. As mentioned above, there are still several disadvantages: firstly, in the production practice of bottle caps with split (main cover body, cover sheet, co...
