Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples given are not intended to limit the present invention.

[0021] Reference figure 1 versus figure 2 As shown, an embodiment of the mold core insert containing conformal cooling water channels of the present invention is used for injection preparation of glasses cases, and includes a core body 1 and one or more conformal cooling water paths arranged inside the core body 2. The core body and the conformal cooling water route are integrally formed by selective laser sintering additive manufacturing. The conformal cooling water route needs to ensure a strong cooling effect, which cannot be processed by traditional drilling processing methods, and The mosaic structure cannot guarantee the cooling effect, so it is manufactured by selective laser si...

Abstract

The invention discloses a mould core insert part containing a conformal cooling water channel. The mould core insert part comprises a core body and a conformal cooling water channel arranged in the core body, wherein the core body and the conformal cooling water channel are integrally formed by a selective laser sintered material, the conformal cooling water channel comprises a plurality of parallel V-shaped water channel bodies, a pipe opening of the V-shaped water channel body at the head end is set as a water inlet, a pipe opening of the V-shaped water channel body at the tail end is set asa water outlet, the pipe openings of the two adjacent V-shaped water channel bodies are connected through U-shaped water channels, a tip part at the bottom of each V-shaped water channel body is setas a transition fillet, and a plurality of centre holes are further arranged in the core body. The mould core insert part disclosed by the invention not only can improve a cooling efficiency of a mould and shorten product cooling time, but also shortens a product forming period, improves a product production efficiency and reduces thermal residual stress of injection molded parts; furthermore, themould core insert part can improve dimensional accuracy of injection molded products and improve product quality.

Description

Technical field [0001] The invention relates to the field of injection molding molds, in particular to a mold core insert containing conformal cooling water channels. Background technique [0002] As we all know, injection molding is a high-efficiency manufacturing method of plastic parts, and its high-efficiency molding relies on injection molds. The injection molding process includes four stages: clamping, injection, holding pressure and cooling. In the entire injection molding cycle, cooling takes the longest time, occupying about 3 / 4 of the entire cycle. Therefore, the key to improving production efficiency lies in how to reduce To reduce this part of the cooling time, it is necessary to improve the cooling efficiency. In addition, due to the different structures of plastic parts, the difference in the cooling rate of different parts will cause uneven shrinkage of the plastic parts. To obtain more uniform cooling, it is necessary to make the temperature of each position of ...
