Problems solved by technology

The heating of the injection mold is to use the liquid channel to feed hot water or steam. The heating or cooling of this kind of mold is generally adjusted according to experience, so the temperature of the mold cannot be accurately controlled, which will eventually affect the quality of the finished product.

Abstract

The invention provides an automatic temperature control mold. The automatic temperature control mold comprises a fixed template, a movable template, a fixed mold core, a movable mold core and an ejecting device; the fixed template is connected with the fixed mold core; the movable template is connected with the movable mold core; a sprue is formed in the fixed template; a pouring runner is formed in the fixed mold core; the sprue is passed to the pouring runner; the ejecting device is connected with the movable mold core; a first liquid channel is formed in the fixed mold core; one end of the first liquid channel is connected with a first liquid inlet pipe, and the other end is connected with a first liquid outlet pipe; and the first liquid inlet pipe is connected to the first liquid outlet pipe through a valve module, a conveying pump and a hot liquid box in sequence. The automatic temperature control mold acquires the temperature of the mold through a temperature sensor, processes the acquired temperature data by a temperature control unit, controls rotation of a motor by a controller to move an ejector rod, controls the openness of a valve to enable the mold to locate in a set temperature range, realizes automatic temperature adjustment of the mold, and guarantees the product quality.

Description

technical field [0001] The invention belongs to the field of injection molds, in particular to an automatic temperature control mold. Background technique [0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts, and is mainly used in the industrial field. The process of injection molding is to inject the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, the finished product is obtained. Mold temperature will affect surface quality, fluidity, shrinkage, etc. The heating of the injection mold is to use the liquid channel to feed hot water or steam. The heating or cooling of this kind of mold is generally adjusted according to experience, so the temperature of the mold cannot be accurately controlled, which will eventually affect the quality of the finished product. Contents of the invention [0003] In view of this, the present invention aims to propose an automatic tem...
