Pouring mold for outer barrel of dust collector

Abstract

The invention relates to a pouring mold for an outer barrel of a dust collector. The pouring mold comprises a lower mold base, wherein a lower mold groove is formed in the lower mold base and is fixedly connected with sliding rails; a lower mold hole is formed in the bottom surface of the lower mold groove; a mold core is arranged in the lower mold hole; brackets are fixedly connected with two ends, positioned on the lower mold groove, of the lower mold base; a cylinder is arranged on each bracket; push rods of the cylinders are connected with a left mold base and a right mold base which are arranged in the lower mold groove; the opposite side walls of the left mold base and the right mold base are arc-shaped; pouring gates are arranged at the tops of the left mold base and the right mold base; a gap is formed between each of the opposite side walls of the left mold base and the right mold base and the mold core, and is communicated with the corresponding pouring gate; sliding holes are formed in the side walls, positioned on the sliding rails, of the left mold base and the right mold base; core pulling blocks are positioned in the sliding holes and are supported on the sliding rails; a pull rod is arranged aslope on each core pulling block; a T-shaped groove is formed in one end part of each core pulling block; a pulling pin is vertically arranged in each T-shaped groove; mold pins are arranged in the left mold base and the right mold base along the parallel direction of the sliding rails. The pouring mold for the outer barrel of the dust collector is simple in structure, high in core pulling efficiency and high in reliability; the product quality is easily guaranteed.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a casting mold for producing an outer tub of a vacuum cleaner. Background technique [0002] Vacuum cleaners are common small household appliances in daily household. The outer barrel is made of plastic parts, which are usually finished by injection molding of plastic injection molds. The design of the mold structure directly affects the efficiency of core pulling of the mold and also has a great impact on the quality of the product. Although the current mold structure can successfully complete the core pulling, the efficiency is low and the poor reliability will easily lead to quality problems of the outer barrel. Contents of the invention [0003] The applicant improves on the above-mentioned shortcomings in the prior art, and provides a vacuum cleaner outer tub casting mold, which has a simple structure, high core-pulling efficiency, good reliability and easy to ensure produc...
