In-mould assembly method

Abstract

The invention discloses an in-mould assembly method, which mainly comprises the following steps: arranging first and second female dies inside and outside an injection table; arranging a male die with double die surfaces between the two female dies; closing the three dies, pouring plastic, ensuring saturation pressure and opening the die, then taking the middle male die out and quickly advancing the first and second female dies to form the die closing program of the two female dies, and quickly finishing the assembly of the two plastic members formed in the first and second female dies when opening the dies for the first time in the mould when closing the two female dies so as to obtain an expected plastic product. The in-mould assembly method provided by the invention gets rid of a plurality of processes for manual assembly, simplifies the manufacturing process, solves the technical problem of large factory building space needed by the plurality of processes, greatly reduces the labour cost so as to have the advantages of meeting the market competition and economic benefit, and solves the problems of poor assembly efficiency and low rate of qualified product caused by different capacities of the staff.

Description

Technical field [0001] The invention relates to an assembly technology, in particular to an in-mold assembly method that can greatly improve assembly speed and efficiency. Background technique [0002] At present, in order to achieve the goals of light weight and low cost, plastic materials are widely used for the necessities used in daily life. Plastic products are molded through mature injection molding technology. The molded plastic parts need to be stored in a centralized manner. , Simple packaging, and transfer to the production line for assembly will invisibly increase the working space and the multi-channel assembly process outside the mold. The complicated and time-consuming technical issues derived from it are quite inconsistent with market competition laws and economic benefits. [0003] The scissor feet (or frog legs) used for support under the keycaps of the notebook keys are currently manufactured using the above-mentioned plastic injection molding inner and outer shea...

AI Technical Summary

Problems solved by technology

And a notebook computer is equipped with more than a hundred buttons, and the annual output of domestic notebook computers is even more than ten million units. If the above-mentioned traditional inner and outer cutting injection molding is used, and then the operation method of manual assembly is applied, not only The assembly efficiency cannot be effectively improved, and a large amount of manual assembly costs is the key to the fact that the cost of the enterprise has not been greatly reduced until today; moreover, the internal and external cutting of the scissors is manually assisted by mechanical arm assembly, and it is easy to be assembled by the assembly personnel. The quality varies from good to bad, resulting in the failure of production capacity and yield to meet the expected goals
