Processing die of dual-color plastic chair and its processing method

Abstract

A processing die for a double-color plastic chair is provided with a casting system, a die cavity, a mold core and a demoulding system; a product mould cavity is arranged between the die cavity and the mold core. The processing die of the invention is characterized in that the mold core is provided with a movable embedded block which is connected with an inclined slide block A; the inclined slide block A is contacted with an inclined slide block B; the slide block B is driven by a pushing air cylinder; the die cavity is provided with two pouring heads; an opening of the first pouring head is arranged on the back surface of the die cavity and the outer layer of an injection plastic chair; an opening of the second pouring head is arranged on the end surface of the die cavity and the inner layer of the injection plastic chair. A seat plate and a backrest of the plastic chair manufactured by the die of the invention are compounded by the inner layer and the outer layer with two different colors; the limit of the colors is clear; compared with a single color chair, the appearance of the invention is beautiful; the product grade is high; the thickness of a manufactured product is large; the mechanical intensity is high and the invention can be applied to work in an office and daily life.

Description

technical field [0001] The invention relates to a processing mold for a two-color plastic chair and a processing method for the two-color plastic chair, belonging to the field of processing plastic products. Background technique [0002] Plastic chairs can be divided into all-plastic plastic chairs and metal tripod plastic chairs. The all-plastic plastic chairs are integral injection or blow molding of the seat board, backrest, chair legs and armrests; the metal tripod plastic chairs are seat The board and the backrest are injection molded, and metal chair feet or bases are installed under the seat board. The seat board and the backrest of the existing metal tripod plastic chair are single-layer structure and single color because they are one-time injection molding. The single-color plastic chair lacks competitiveness in the market because of its monotonous color, unattractive appearance, and low product grade. , poor economic benefits. But if two-color plastic chairs are ...
