Manufacturing and forming equipment for microporous resin products

Abstract

The invention provides manufacturing and forming equipment for microporous resin products, which integrates a preheat unit [2], a heating unit [3] and a cooling unit [4] as a whole. A preheater, a heater and a cooler are arranged in the body according to the sequence of the units. Forming moulds are orderly transferred from the preheat unit to the heating unit and then to the cooling unit by a forming mould transporter so that operation of each step is performed in each special unit and associated together organically. In addition, the work state of the work devices is controlled by a computer control system in a control box [1]. Compared with prior art, the invention is free from the operation mode where energy source is wasted by heating and then cooling the work mould and cooling and then heating the work mould and avoids the operation mode where many control deficiencies caused by transferring the forming mould from a work device to another work device, thereby preventing the deficiency of reduced controlled property of micropores of products in diameter and distribution caused by inaccurate control of temperature changing range and speed of the forming mould in the whole process.

Description

technical field [0001] The invention relates to a manufacturing and molding equipment of microporous resin products, especially the manufacturing and molding equipment of microporous resin products with thermoplastic resin as the base material, belonging to the technical field of plastic product manufacturing. technical background [0002] Microporous resin products refer to resin-based products with a pore density of 109-1015cell / cm 3 , micropores with a pore diameter of 0.1-200mm, and a density of 0.05-0.95g / cm 3 products. The micropores in microporous resin products are divided into open-cell micropores and closed-cell micropores. Open-cell micropores are interconnected between pores, while closed-cell micropores are interconnected between each hole. closed. [0003] Microporous resin products have high rigidity and excellent impact resistance, heat insulation, sound absorption and shock absorption, and the single component is convenient for recycling. According to th...

Problems solved by technology

However, this type of equipment needs to be heated and cooled on two or more compression molding machines, and plastic micropores need to be manually transferred from the compression molding machine used for heating to the compression molding machine used for cooling during the molding process. machine

Therefore, there are disadvantages such as complex process, long process and high cost

However, the above two types of equipment will cause temperature changes and speed uncertainties during the switching process during operation, resulting in low controllability of the micropore diameter and distribution of the product, and a high rejection rate.
