Problems solved by technology

[0004] In view of the above-mentioned complex plastic products, it is often inconvenient to open the movable mold and the fixed mold. The injection molding cannot be completed in one step, and the injection precision can only be reduced. The shape requirements are achieved through post-processing, which is not conducive to the production efficiency of the enterprise. In order to solve the problem of poor controllability of the mold forced cooling heat transfer speed, the invention provides a forced cooling injection mold device

Embodiment 1

[0026] like figure 1 As shown, a forced cooling injection mold device includes a front baffle 5, a plurality of cavity plates 6 and a rear baffle 7 with cavities inside, and a plurality of cavity plates 6 are located between the front baffle 5 and the rear baffle 7. Between the rear baffles 7, and a plurality of the cavity plates 6 are arranged sequentially, the adjacent two cavity plates 6, the front baffle 5 and the cavity plate 6, the cavity plate 6 and the rear baffle 7 The sides are attached to each other, and the front baffle 5, the plurality of cavity plates 6 and the rear baffle 7 are all provided with a plurality of flow channels communicating up and down, and the front baffle 5 is also provided with injection holes 2, The tailgate 7 is also provided with exhaust holes.

[0027] The set front baffle 5, multiple cavity plates 6 and rear baffle 7 are combined to form the cavity of the injection mold, and the cavity part is composed of front baffle 5, multiple cavity pl...

Embodiment 2

[0029] This embodiment is further defined on the basis of embodiment 1, as figure 1 As shown, it also includes drainage tube interfaces 1 whose number is twice the number of flow channels, and the drainage tube interfaces 1 are respectively arranged at the inlet and outlet of each flow channel.

[0030] The provided drainage tube interface 1 facilitates the connection between the flow channel and the external pipeline in the present invention.

[0031] It also includes a drainage tube 3, the drainage tube interface 1 is a common quick connector for gas and liquid, the drainage tube 3 is a plastic hose, and the free ends of the drainage tube 3 are fixedly connected to any two drainage tube interfaces 1 .

[0032] The set plastic hose and the gas-liquid shared quick connector are easy to pull out and insert, and the connection is reliable, and the sealing performance of the connection surface is good.

[0033] The front baffle plate 5, the plurality of cavity plates 6 and the c...

Abstract

The invention discloses a forced cooling injection mold device, which comprises a front baffle (5), a plurality of mold cavity boards (6) with cavities formed in inner sides, and a back baffle (7), wherein the plurality of mold cavity boards (6) are positioned between the front baffle (5) and the back baffle (7), a plurality of flow passages of which the upper parts and the lower parts are communicated are arranged in the front baffle (5), the mold cavity boards (6), and the back baffle (7) respectively; a injection molding hole (2) is formed in the front baffle (5); an exhaust hole is formed in the back baffle (7). The cavity parts of mold cavities are formed by the combination of a plurality of parts, so that the mold is allowed to be able to adapt to mold opening of the mold cavities with complex shapes, the enhance of the injection molding precision of plastic products with complex shapes is facilitated, and subsequent reprocessing is eliminated or reduced; the arranged flow passages facilitate the selection of an optimum cooling manner according to a specific material property for better adapting to requirements of cooling speed required to be maintained of the plastic injection molding of different plastics, and therefore, the improvement of the production efficiency of enterprises and the quality of products are facilitated.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to a forced cooling injection mold device. Background technique [0002] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted materials into a mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. Injection mold is a tool for producing plastic products, which gives plastic products complete structure and precise dimensions. [0003] Existing injection mold is made up of two parts of movable mold and fixed mold, and movable mold and fixed mold are closed to form gating system and mold cavity during injection molding, and movable mold and fixed mold are separated so that take out plastic product when mold is opened. However, due to the ever-changing shapes and structures of plastic products, plastic products with complex sh...
