TW201008513A - Cold fusion in-mold sports helmet - Google Patents

Abstract

A cold fusion in-mold sport helmet is formed by attaching a temperature-resistant protective tape to one side of a nop-temperature-resistant plastic sheet, followed by printing, plastic removal, trimming, and hole forming, to form an outer helmet shell. The outer helmet shell and a pre-formed inner helmet member are disposed together in a molding machine to be molten at a lower pressure and a lower temperature in a shorter time to make an integrally-formed sports helmet.

Description

.201008513 • IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of making a head, a method of making a head, and a method of forming a cold fusion in-mould helmets. [Prior Art] Sports head cover (four) unearthed record (10) helmets), financial disk honesty • hdmetS), ski helmet (snow he-ts), mountaineering helmet (climbing hdmet^ horse fine (four) helme_ knots are different. But such as _- The high-profile head of the body-formed structure is a housing made of pc. The inside of the casing is filled with a light and soft material layer to form a contact between the head and the head. When a collision occurs, the light and soft inner helmet will be It is responsible for shock absorption buffer. The materials used in the above cover are generally high in high unit price pc. Since the cost of raw materials is high as the price of oil continues to rise, manufacturers must use lower-cost materials to cope with the increase in manufacturing costs. Μ, ρΕτ, pCTG are the alternative materials that are locked. Since the above-mentioned cheap substitute materials have physical properties that are not resistant to high temperatures, they can be completed by steaming at a low temperature of Chengcai Lai. [Summary of the Invention] The approval is to provide a kind of cold-melting lion head 盍, which will be made into a plastic plate with a high-temperature resistant film on one side, and then made into an outer disk shell by printing, sucking, cutting and cutting holes; Formed outer disk The housing, "pre-formed inner disc is placed together in the mold of the molding machine, and is steamed and melted into a integrally formed moving head with a lower force, lower temperature than 5 201008513. [Embodiment] The object of the present invention It can be realized by the following technical solutions: Printing, blistering, trimming after the high temperature resistant plastic sheet such as PVC, PET, PETG is pressed against the high temperature (about 120 ° C) protective film. The outer casing shell is made by cutting and other processes; φ the formed PVC, PET, and PETG outer helmet shells are placed together with the formed expandable polystyrene (EPS) in the molding machine. The mold is steamed into a one-piece sports helmet at a lower pressure (〇.5±〇.lbar), lower temperature (ιι〇±2 °C), shorter time (168±5 sec). The melt-formed sports helmet can achieve the same appearance, function, collision protection and impact resistance as the traditional high-priced PC outer helmet. The sports helmet made by the above-mentioned cold-melt molding, due to PVC, PET, PETG 0 The cover and the EPS inner helmet are integrally formed without any gap, thereby uniformly dispersing After the stress safety in order to protect the head.

The sports helmet made by the above-mentioned cold-melt molding can avoid the disadvantage that the PVC, PET, PETG outer disc is glued or taped with the EPS inner helmet, and is not resistant to deformation by the sun.
