Rotary de-molding system

Abstract

The invention provides a rotary de-molding system. The rotary de-molding system comprises a base and a mould core assembly, wherein the base comprises a containing through hole which extends along the vertical direction; the mould core assembly is arranged in the containing through hole in a penetrating manner; the mould core assembly comprises a mould cavity; a plurality of balls are movably arranged on the outer side of the mould core assembly and lean against the side wall of the containing through hole; the mould core assembly is matched with a pushing-out assembly through horizontal rotation of the plurality of balls in the containing through hole to finish the rotary de-molding of a molding plastic part. According to the rotary de-molding system, the mould core assembly is contained in the containing through hole and the balls are movably arranged on the mould core assembly; the mould core assembly is matched with the pushing-out assembly below the mould core assembly by horizontally rotating the plurality of balls in the containing hole so as to realize the rotary mould stripping of the molded plastic part; with the adoption of a ball rotating manner, the service life is guaranteed, the maintenance cost of the rotary de-molding system is reduced and the rotary de-molding system has a good market prospect.

Description

technical field [0001] The invention relates to the field of mold casting, in particular to a rotary demoulding system. Background technique [0002] With the continuous development of new materials, some physical properties of many new materials have approached or exceeded metals. At the same time, they have far surpassed metals in terms of acid and alkali resistance and corrosion resistance. Among the aforementioned new materials, common plastics are due to It has many advantages such as strong plasticity, strong chemical corrosion resistance, and good insulation, which are widely used in some aspects. [0003] At present, plastic products with complex shapes are mostly prepared by combining injection molding and subsequent ejection and demoulding. The ejection direction of the part during the demoulding process is inconsistent, so that the molded plastic part needs to provide additional rotational force during the demoulding process to make the molded plastic part rotate...

Problems solved by technology

[0003] At present, plastic products with complex shapes are mostly prepared by combining injection molding and subsequent ejection and demoulding. The ejection direction of the part during the demoulding process is inconsistent, so that the molded plastic part needs to provide additional rotational force during the demoulding process to make the molded plastic part rotate during the ejection process, so as to complete the rotary demoulding of this kind of plastic part , the existing rotary demoulding system usually adopts a rotating channel in the injection molding machine, and a clamping part is set on the periphery of the cavity wall, and the clamping part cooperates with the rotating channel to drive the cavity wall to rotate, but the clamping part is used The combination of the holding part and the rotating channel needs to provide a large driving force to drive the rotation of the cavity wall, which increases the demoulding energy consumption of the rotary demoulding system. At the same time, the maintenance period of this rotating channel is short, which increases the Maintenance costs for rotary demolding systems
