Mold temperature control device

Abstract

A mold temperature control device comprises steam storage tanks, heating tanks and a heat exchanger. A steam guide pipe for steam output is arranged on one steam storage tank. The heating tanks are provided with water inlets, heating pipes are arranged in the heating tanks, and the heating tanks are connected and communicated with the steam storage tanks through steam conveying pipes. The heat exchanger is provided with a cold water inlet, a hot water outlet, a steam recovery opening and a condensate water drainage opening. The hot water outlet is connected with the water inlet of the heating tanks. The mold temperature control device is characterized in that the steam storage tanks and the heating tanks are all in strip shapes and are arranged in a vertically spaced mode, the number of the steam conveying pipes is at least three, and the steam conveying pipes are arranged at the two ends and the middles of the steam storage tanks. Compared with the prior art, the mold temperature control device has the advantages that by means of multi-channel design, enough steam in the heating tanks can enter the steam storage tanks at the same time, the saturability of the steam output out of the steam storage tanks is relatively high, and therefore the heat transfer effect of the output steam is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mold temperature control devices, in particular to a mold temperature control device that can be used for a mold temperature controller for injection molding. Background technique [0002] The mold temperature controller for injection molding is the temperature control equipment of the injection molding machine. Among them, the mold temperature control device is an important part of the mold temperature controller, which is directly related to the weld marks on the surface of the injection molded product. Provide conditions for rapid temperature rise, and, for high-standard high-gloss non-marking mold temperature machines, it is necessary to be able to rapidly heat up and cool down to obtain high-quality products, while the mold temperature control device in the prior art is due to steam Insufficient quantity or unstable working pressure will easily lead to unstable operation of the mold temperature contr...

AI Technical Summary

Problems solved by technology

[0006] First, the pipes between the heating tank and the gas storage tank are relatively narrow and limited in number, resulting in poor steam saturation, resulting in steam heat transfer effects, and affecting the quality of finished products of the injection molding machine

[0007] Second, compared with the traditional mold temperature control device, if the steam is saturated and continues to heat, dry burning will occur, which wastes energy and reduces the heat transfer effect. This problem still exists and has not been resolved.
