Security risk；D) Workshop Production environment is easily polluted.The problem that in order to overcome thermal cycle mode of heating, now generally adopt
Heated with electrical bar, the concrete operations of electrical bar mode of heating are：Appropriate location drilling in a mold, and electrical bar is inserted into,
Electrical bar is heated by the cooperation of temperature sensor and heating control system afterwards, using the heat of electrical bar conduct to
In core rod, and electrical bar and core rod are in point contact, and contact area is small, electrical bar is set some, i.e., need to be big according to mould
Small and fever tube power determines heat-generating pipe quantity and density；Electrical bar heating has the disadvantage that：A) limited by space, electricity
Hot pin lays trouble, and easily occurs because power does not reach the requirement of mould temperature not enough, or exceedes the requirement of mould temperature because power is excessive, causes
Hot-spot phenomenon, can not meet mould temperature demand, cause injection molded quality unstable；B) it is big to easily cause regional temperature,
Heat uneven, cause injection molded of poor quality；C) Kong Yin between electrical bar and mould is more difficult to be bonded and causes completely
Electrical bar overheat causes short circuit to burn out, and service life is short.
In view of this, the present inventor furthers investigate the above problem, is produced then by this case.
