AI Technical Summary

Problems solved by technology

However, the reduction of the temperature of the molten resin will lead to the weakening of the fluidity of the molten resin in the metal mold cavity
This in turn leads to molding defects

Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] An injection metal mold 1 according to a preferred embodiment of the present invention is used to produce a battery for a cell phone in a cell system as shown in FIG. Made in one piece. Specifically, as shown in FIGS. 1 and 2 , an injection molding metal mold 1 (hereinafter simply referred to as a metal mold 1 ) fixedly holds and arranges a battery cell (or mounted member) 3 within a cover 2 . The metal mold 1 has a lower mold 5 and an upper mold 6 which can be separated vertically from each other and joined together by clamping. Reference numeral 7 in Fig. 3 denotes a terminal for realizing electrical connection between the battery 4 and the cell system mobile phone body (not shown in the figure), and reference numeral 8 denotes a terminal for establishing the battery 4 and the cell system An insert that fits between mobile phone bodies. That is, the battery 4...

Abstract

PROBLEM TO BE SOLVED: To prevent the generation of molding defectiveness by suppressing the lowering in the flowability of a resin while preventing the deformation of a case such as a battery lid or the like arranged in a mold. SOLUTION: The injection mold 1 has a case 2 arranged in the cavity formed therein and is used in order to fill the gap between the case 2 and the loaded part 3 arranged inside the case 2 with a molten resin. This injection mold 1 is equipped with the groove 13 opened to the cavity at the position covered with the case 2 and both of the cooling medium supply port 15 and the cooling medium discharge port 16 communicating with the groove 13.

Description

technical field [0001] The invention relates to a metal mold of an injection molding machine. The injection molding machine is used for injection molding with a predetermined resin material, so that mechanical parts such as batteries and / or electrical components are fixedly arranged on the casing and integrated with the casing. In particular, a metal mold is used for injection molding to produce a battery, and a resin material is used to integrate the battery cell and the cover, and the battery is suitable for use in devices such as mobile phones. Background technique [0002] Common resin injection molding techniques for batteries of portable telephone devices such as cell-based mobile phones and PHS (Personal Handyphone System) terminals are disclosed in documents such as Unexamined Japanese Patent Application No. 2000-315483. Wherein, the battery unit is fixed on the inner surface of the battery cover and set in a metal mold, and then the metal mold is filled with predete...
