Injection mold for shell cover of magnetized filter device for direct drinking water

Abstract

The invention discloses an injection mould of a direct drinking water magnetization filter housing cover. The injection mould comprises an upper mould assembly, a lower mould assembly, a guide component and an ejector mechanism. The upper mould assembly and the lower mould assembly undergo guided closing through the guide component and are locked through a locking device to form a mold cavity of a direct drinking water magnetization filter housing cover product (11). Part of components of the ejector mechanism are in sliding fit in the lower mould assembly. A metal insert (12) is arranged inside the mold cavity of the direct drinking water magnetization filter housing cover product (11), and the metal insert (12) is placed on an end portion of a push rod (10) in the ejector mechanism. By the adoption of the above structure, as the end portion of the push rod in the ejector mechanism is tightly abutted against the metal insert inserted inside the product in the injection mould and the metal itself has high hardness and high rigidity, deformation, pit and other defects will not happen to the housing cover during the ejection process after injection. Thus, qualified rate of the product can be greatly raised.

Description

technical field [0001] The invention relates to the technical field of mechanical moulds, in particular to an injection mold for a shell cover of a direct drinking water magnetization filter device. Background technique [0002] Water is an essential material for human survival, and with the acceleration of industrialization and the improvement of human living standards, more and more drinking water issues have attracted people's attention. At present, the direct drinking water dispensers that appear on the market are devices that use water after a certain single or multiple multi-layer filtration, and in addition to magnetization and other devices. In the prior art, the shell covers of the above-mentioned magnetized filter devices are usually formed by injection molding of plastic raw materials through an injection molding machine. The end face of the ejector rod of the ejector mechanism of the mold directly contacts the end face of the shell cover. When being ejected from...
