Problems solved by technology

In the production process of side keys, usually multiple side keys are injection molded at one time in the side key injection molding device, so that the production efficiency can be improved. However, due to the characteristics of large thickness and irregular shape of side keys, the existing side keys In the injection molding process of the key, usually a separate gate and runner are configured for the molding area of ​​each side key, which often results in a large amount of waste and high production costs. If the gate is shared, it is far away from the gate. Side keys often have various production defects and unstable quality

Embodiment 1

[0028] Such as Figure 1-2 As shown, it represents a side key injection molding device provided by the present invention. The side key injection molding device includes a male mold frame, a male mold core 2 arranged in the male mold frame 1, a female mold frame 3 corresponding to the male mold frame 1, and a female mold frame 3 arranged in the female mold frame 3. The female mold core 4 ; the said female mold frame 3 is provided with a hot runner plate 5 and a plurality of gates 6 . Specifically, in this embodiment, the female mold base 3 can cooperate with the injection molding machine, and the molten injection molding raw material is provided by the injection molding machine and kept in a molten state through the hot runner plate 5 to realize the injection of the injection molding raw material through multiple gates. An ejection mechanism may be provided in the mold base 1 and cooperate with the ejector rod of the peripheral machine to realize the ejection of the side key p...

Embodiment 2

[0035] Such as Figure 7 As shown, it represents a side key injection molding method provided by the present invention, comprising the following steps:

[0036] Injection molding machine and the side key injection molding device provided in the above embodiments are provided;

[0037] Provide molten injection molding raw materials through the injection molding machine, and maintain the molten state of the molten injection molding raw materials through the hot runner plate;

[0038] After the molten injection molding raw material is solidified in the product forming area of ​​the molding cavity of the side key injection molding device to form a side key product, the mold is opened.

[0039] Of course, specifically, in this embodiment, when it is necessary to realize a two-color side key product, specifically, after forming a color part of the side key product and opening the mold, it also includes rotating or moving the male mold frame to the same position as the second color ...

Abstract

The invention provides a side key injection molding device and method. The side key injection molding device comprises a male mold frame, a male mold core arranged in the male mold frame, a female mold frame corresponding to the male mold frame, and a female mold core arranged in the female mold frame; the female mold frame is internally provided with a hot runner plate and a plurality of sprues;and the male mold core and the female mold core are matched to form a forming cavity, the forming cavity comprises a plurality of sets of product cavities and a plurality of runner cavities connectedwith the product cavities in a one-to-one correspondence mode, the product cavities comprise a plurality of product forming areas used for forming side keys, and a flow limiting opening is formed in the junction of each runner cavity and the corresponding product forming area. According to the side key injection molding device and method, generation of waste is effectively lowered, the productioncost is lowered, and the production efficiency is effectively ensured; and the runner cavities connected with the product cavities in the one-to-one correspondence mode are formed, the flow limiting opening is formed in the junction of each runner cavity and the corresponding product forming area, and thus the product quality is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a side key injection molding device and method. Background technique [0002] A side key is a key commonly used in various electronic devices, such as a volume key, a power key, and the like applied in a mobile phone. Side keys are generally produced by injection molding, which refers to injecting thermoplastics or thermosetting plastics into injection molds to make plastic products of various shapes. In the production process of side keys, usually multiple side keys are injection molded at one time in the side key injection molding device, so that the production efficiency can be improved. However, due to the characteristics of large thickness and irregular shape of side keys, the existing side keys In the injection molding process of the key, usually a separate gate and runner are configured for the molding area of ​​each side key, which often results in a large amou...
