Novel fiberglass mold for notebook production

Abstract

The invention relates to the technical field of molds for notebook production, and in particular, relates to a novel fiberglass mold for notebook production. A cavity insert waterway which can regulate the temperature of a cavity insert is arranged in the cavity insert; a feed hopper is arranged in a core insert; hot runner water jackets are arranged on two sides of the feed hopper, and a cooling waterway is arranged outside each hot runner water jacket. The cavity insert waterway comprises a cavity insert waterway I and a cavity insert waterway II. An oil temperature machine with low investment cost and maintenance cost is adopted for keeping the temperature of the mold constant; a needle-valve hot runner of a backflow mold is adopted for gating, the hot runner water jackets are additionally arranged, an optimal material handle scheme is analyzed through CAE, and the development cost of the mold is reduced; the cavity insert corresponding to the appearance of a product is designed with double layers of waterways, so that the temperature of a cavity mold is constantly kept at 110 DEG C; after the design scheme is improved, the scope of molding conditions is wider, the appearance and deformation of the product is controlled better, and the yield in mass production is increased to more than 95%; and the requirement of mass production is met, and the novel fiberglass mold has a good effect.

Description

technical field [0001] The invention relates to the technical field of molds for notebook production, in particular to a novel glass fiber mold for notebook production. Background technique [0002] In order to improve the strength of the product structure, glass fiber has been widely used in plastic products such as notebook casings and auto parts. A large number of facts have also proved the good performance brought by glass fiber. However, glass fiber and plastic are two different materials, which will cause compatibility problems. Floating fiber is a direct manifestation of the compatibility problem between the two. The traditional method is to use a rapid heating (RHCM) mold to solve the problem of floating fibers. Using a rapid heating mold will have the following problems: the cost of heating equipment is high; the development of the mold is more complicated and the processing is difficult; The parts are cracked and damaged; the molding technology requirements are hi...

Problems solved by technology

However, glass fiber and plastic are two different materials, which will cause compatibility problems. Floating fiber is a direct manifestation of the compatibility problem between the two.

The traditional method is to use rapid heating (RHCM) molds to solve the problem of floating fibers. Using rapid heating molds will have the following problems: the cost of heating equipment is high; The parts are cracked and damaged; the molding technology requirements are high, and the mass production yield is low, only about 65%
