Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] refer to Figure 4 , is a preferred embodiment of the forming method of the composite shell of the present invention, comprising a material preparation step 41, a preparation step 42, a pre-step step 43, a forming step 44, and a demoulding step 45 carried out in sequence .

[0022] In this material preparation step 41, please also refer to Image 6 , prepare a base material 5 formed by stacking multiple reinforcing layers and multiple thermoplastic substrates, the volume of the base material 5 is precisely calculated so that the base material 5 can meet the requirements of net size molding after processing, Since the calculation process is not the subject of the present invention, details are not repeated here, nor should it be limited thereto. In this preferred embodiment, the material of the reinforcing layer is selected from one of glass ...

Abstract

The invention discloses a method for forming a composite shell. The method for forming the composite shell comprises a material preparing step, a preparation step, a prearranging step, a forming step and a demolding step. In the material preparing step, a base material having thermoplasticity is prepared. In the preparation step, a mold is prepared. The mold comprises a female mold body and a male mold body used in cooperation with the female mold body. A molding space is defined through the cooperation of the male mold body and the female mold body. In the prearranging step, the base material is placed on the male die body and softened by heating the male mold. In the forming step, the male mold body and the female mold body are combined, and the female mold body is pressurized to make the base material be squeezed into the molding space to form a shell with edge lead corners. In the final demolding step, the male mold body and the female mold body are separated after the shell is hardened by cooling, and the shell is taken out. Through all the above steps, the composite shell with the edge lead corners can be formed, and the procedure of secondary machining is omitted.

Description

technical field [0001] The invention relates to a molding method, in particular to a molding method of a composite material shell. Background technique [0002] With the evolution of science and technology and the popularization of the Internet, intelligent electronic products have become an indispensable necessity in people's life. Under the high competition of various electronic products, in addition to the basic demands of high strength and light weight, the casing of electronic products , Appearance and shape are the key items that affect consumers' purchases. The composite material formed by adding fibers has the characteristics of high strength, light weight, and high plasticity, so it can meet the above-mentioned requirements, so it is very popular among the industry and consumers. [0003] The general composite shell manufacturing method is to use thermoforming, such as figure 1 , 2 As shown, a thermoplastic thermoplastic sheet 1 is first inserted into a mold cavi...
