Embodiment Construction

[0020] The present invention provides an in-mold assembly method. The in-mold assembly technology is mainly used in the field of plastic products with a wide range of applications. In order to make the core means of the in-mold assembly technology, it can obtain valuable review members and be familiar with this technical field. Those who need to know more about it and implement it accordingly. The example of the diagram is described in detail with the scissor feet used to support the keycaps of the keyboard, but it is not an attempt to limit the in-mold assembly technology. It is only applied to the structure of the scissor feet. .

[0021] First as Figure 1A~1D As shown, the main structure of the in-mold assembly method of the present invention applied to the scissor foot plastic products includes:

[0022] At least two female molds, the first female mold 10 and the second female mold 20, the first female mold 10 is arranged inside the injection machine (not shown), and the secon...

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...
