Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Such as Figure 1-3 shown.
[0017] The working process of the present invention is: after receiving relevant signals from the injection molding machine, provide power for the high-efficiency heating tube, ensure that the cavity temperature of the mold reaches the specified range within a specific time, so as to ensure that the production process of the high-gloss mold meets the technological requirements, Meet the production conditions of high-gloss products, such as figure 1 shown.
[0018] The first control signal lamp of the electronic control system of the present invention is as figure 2 Shown:
[0019] figure 2 (a) is the indicator light circuit: the green light is the working indicator light, when the KM0 AC contactor is working, the green light is on, indicating that the host of the device is started. The red light is an alar...

The invention relates to an electronic control system of an injection molding machine for controlling temperature by using time; the electronic control system comprises a master switch (QF2); a normally open contact (1) of the master switch (QF2) is connected with a normally open contact 2 of a flowing-through Z phase sequence disconnection protector; the normally open contact 2 of the flowing-through Z phase sequence disconnection protector is connected with a normally closed contact 3 of an emergency stop switch (SB1); the electronic control system is characterized in that the normally closed contact 3 of the emergency stop switch (SB1) is connected with a heating coil start-up circuit, a knob switch control circuit, a time protective circuit, an over-temperature alarm circuit, a time control warming circuit and a warming control circuit; the electronic control system is suitable for injection molding operation of electric heating highlight products, effectively ensures the demands of each region of the cavity of the mold for temperature through the time adjustment of each time slot, meets the molding requirements of the highlight products and is necessary equipment for producing the electric heating highlight injection molding products.
Description
technical field [0001] The invention relates to an electric control system of an injection molding machine, in particular to a temperature control system of an injection molding machine capable of producing high-gloss products, specifically an electric control system of an injection molding machine that controls temperature by using time. Background technique [0002] At present, in the injection molding system that is developing particularly rapidly, hot runner technology and high-gloss mold molding technology are increasingly used in actual production operations, and the temperature control function of injection molding auxiliary equipment is added to meet the production of high-gloss products. [0003] At present, the technology of using electric heating to rapidly heat the molds of injection molding machines is very popular, and it is used more and more in high-gloss molds. Because the surface quality requirements of high-gloss products are very strict, the temperature st...
