Circuit device of injection mold with single-side inlet and outlet cooling water

Abstract

The invention discloses a circuit device of an injection mold with single-side inlet and outlet cooling water, which comprises a water-stop plate (1), a water faucet (2), a support plate (3), a plug (4), a water inlet channel (6), a folded-back channel (61), a water outlet channel (7), and a water-turning cooling hole (8). The present invention adopts such a technical scheme of cooling water circuit that the water-turning cooling hole consisting of several straight blind holes is arranged in the mold, an isolating device consisting of the water-stop plate, the water faucet and the support plate partitions the water-turning cooling hole into a water turning chamber and a water returning chamber from top to bottom; the water inlet channel and the water outlet channel provided with the straight holes are respectively communicated with the water turning chamber and the water returning chamber and then respectively connected with them by the folded-back channel of the straight hole, and the inlet and the outlet are arranged on the same outer side of the mold. By using the water faucet for partitioning the water inlet and the water outlet channels and the processing convenience of straight hole, the injection mold has inlet and outlet water on the single side, the purposes of simplifying structure, reducing processing cost, no restrict and improving cooling effect are achieved.

Description

technical field [0001] The invention relates to a water cooling device for an injection mold, in particular to a circuit device for cooling water entering and exiting the cooling mold from one side of the injection mold. Background technique [0002] The injection mold enters and exits the cooling water on one side for water cooling, which is often affected by the position of ejector pins, screws and inserts. The existing technology adopts the method of surrounding the formwork, and sometimes it needs to transition through inclined holes or even pass through other formworks. , making the structure of the waterway complex, making it difficult to process and maintain the waterway, and at the same time increasing the length of the waterway and the pressure loss of the water flow, reducing the cooling effect of the mold; problems and deficiencies. Contents of the invention [0003] Aiming at the problems and deficiencies in the above-mentioned prior art, the present invention...

[0002] The injection mold enters and exits the cooling water on one side for water cooling, which is often affected by the positions of ejector pins, screws and inserts. The existing technology adopts the method of surrounding the formwork, and sometimes it needs to transition through inclined holes, or even pass through other formworks. , which makes the structure of the waterway complex, difficult to process and maintain the waterway, increases the length of the waterway and the pressure loss of the water flow, and reduces the cooling effect of the mold; therefore, the existing technology has complex structure, high processing cost, easy to be limited, and poor cooling effect problems and deficiencies
