Abstract

The invention belongs to the field of mold temperature control, and particularly discloses an intelligent temperature control method of a mold for decorative sheet injection molding. The following scheme is put forward to solve the problem that according to an existing mold, heat is prone to being lost, temperature monitoring points are set, and temperature sensors are arranged at equal intervalsin the raw material flowing direction of the mold; a thermal insulating coating is smeared, the outer wall of the mold is evenly smeared with insulating mold coating, and a temperature controller is arranged on the exterior of the thermal insulating coating; an alarming apparatus is also arranged and connected with the temperature controller, and the temperature controller is also connected with aheating device and a cooling device which are arranged on the mold; and when the temperature is lower than a preset value, the temperature controller controls the heating device to run to heat the interior of the mold, when the temperature is higher than the preset value, the temperature controller controls the cooling device to run to cool the interior of the mold, and when the temperature is higher than an alarm value, the alarming apparatus runs to remind a worker to carry out operation. According to the intelligent temperature control method of the mold for decorative sheet injection molding, the design is ingenious, the method is reasonable, the temperature control is reasonable, and the intelligent temperature control method is suitable for being used and popularized.

Description

technical field [0001] The invention relates to the technical field of mold temperature control, in particular to an intelligent temperature control method of a mold for injection molding of decorative panels. Background technique [0002] With the rapid development of the car industry, especially the urgent need for the expansion of the domestic small car market, major OEMs require to improve the production efficiency of products; the sub-dashboard is installed on the instrument panel, or as an accessory on the steering column The instrument panel assembly is like a window, reflecting the running status of the machine inside the vehicle at any time; at the same time, the decorative panel in the middle of the sub-dashboard is the control center of some equipment and the object to be decorated, and is the most eye-catching part in the cab. It is one of the representatives of the vehicle style. The decorative panel in the middle of the auxiliary instrument panel is a plastic ...
