Problems solved by technology

[0002] Vacuum cleaner is a common small household appliance in daily household. Its outer barrel is made of plastic parts, which are usually finished by plastic injection mould. The design of the mold structure directly affects the efficiency of mold core pulling 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

Abstract

The invention relates to a core-drawing structure of a dust collector outer barrel casting die. The core-drawing structure of the dust collector outer barrel casting die comprises a lower die base, wherein a lower die slot is formed in the lower die base; sliding rails are fixedly connected to two sides of the lower die slot; brackets are fixedly connected to two ends, located in the lower die slot, of the lower die base; cylinders are mounted on the brackets; push rods of the cylinders are connected with a left die base and a right die base in the lower die slot; sliding holes are formed in side walls, located in the sliding rails, of the left die base and the right die base; core-drawing blocks are arranged in the sliding holes and supported on the sliding rails; pull rods are tilted on the core-drawing blocks; the core-drawing blocks are in sliding fit with the pull rods; T-shaped slots are formed in the ends of the core-drawing blocks; drawing pins are vertically mounted in the T-shaped slots; L-shaped steps are arranged on contact bottom surfaces between the core-drawing blocks and the sliding rails; when closing the die, gaps are formed between the side walls of the L-shaped steps and the sliding rails; die pins are mounted in the left die base and the right die base in directions parallel to the sliding rails; the ends of the die pins are contacted with the ends of the drawing pins. The core-drawing structure of the dust collector outer barrel casting die is simple in structure, high in core drawing efficiency, excellent in reliability and capable of easily guaranteeing the quality of products.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a core-pulling structure of a casting mold used to produce an outer barrel 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 the above-mentioned shortcomings in the prior art, and provides a core-pulling structure for the casting mold of the vacuum cleaner outer barrel, which has a simple structure, h...
