Intelligent injection mold temperature control method

Abstract

The invention discloses an intelligent injection mold temperature control method. The method comprises the steps that n detection areas A<1>, A<2>...A<n> are prearranged on a lower cover plate of an injection mold; heating devices B<1>, B<2>...B<n> corresponding to the A<1>, the A<2>...the A<n> one to one are prearranged, wherein a target temperature value R<1>, a target temperature value R<2>...atarget temperature value R<n> are preset in the B<1>, the B<2>...the B<n> respectively; a current temperature value T of any one detection area in the A<1>, the A<2>...the A<n> is acquired, wherein 1<=i<=n; and the T is compared with the corresponding R, and the heating device B is started to heat the detection area A according to a comparison result. Therefore, the detection areasand the heating devices are prearranged on the lower cover plate of the injection mold, the temperature values of the detection areas are monitored in real time when a solution is diffused in the mold, when the temperature values in the detection areas are lower than a preset temperature value, the corresponding heating devices are started to heat the detection areas, and then it is guaranteed that the temperature value of the solution over the detection areas is kept within the preset technical specification requirement range.

Description

technical field [0001] The invention relates to the field of mold injection technology, in particular to an intelligent temperature control method for an injection mold. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding molds are widely used in the plastic product processing industry. Injection molds are generally adapted for thermoplastic thermoforming. Utilizing the hot-melt principle of thermoplastics, the molten plastic is injected into the cavity of the mold through the injection molding machine, then cooled and shaped, and the mold is opened to take out the plastic product. [0003] In the process of injection molding a large-area product, due to the poor fluidity of the plastic raw material, the temperature of the melt in the mold will gradually decrease with the diffusion of the melt, often because the temperature of the melt doe...

Problems solved by technology

[0003] In the process of injection molding a large-area product, due to the poor fluidity of the plastic raw material, the temperature of the melt in the mold will gradually decrease with the diffusion of the melt, often because the temperature of the melt does not meet the technical requirements, thus affecting the plastic. The stability of product quality may cause deformation of plastic products or even waste products in severe cases
