In traditional flooding shaping production technology, select suitable flooding mould according to the production demand earlier and install on the production line, get into the oven and carry out the design heating after the mould soaks the stoste, and traditional heating method divide into mould external heating and mould internal heating in the heating form, and in the heating form of mould outside, the heat-generating body is inside the oven, and the mould that needs the heating is heated after the oven to reach the purpose of being heated. In the heating mode inside the mold, the mold can generate heat, and the oven only plays a role in heat preservation. Most of the two heating modes use steam or electric resistance to generate heat, and the few heating modes use heating modes such as infrared rays and the like.
Aiming at the two heating modes, wherein the heating body and the mould are arranged in the oven in the mode of heating the outside of the mould, the heat-conducting medium is air in the oven, and the air is a poor heat conductor as well known, so that a plurality of fans are required to be added in the oven to disturb the air so as to increase the heat transfer coefficient, thereby not only increasing the heat loss, but also virtually increasing the extra power consumption, and leading the efficiency of the whole heating system to become lower.
The heating mode inside the mold is that an electric heating tube is arranged inside the mold for energy conversion, so that the heat efficiency of a heating system outside the mold is improved, but some new problems are introduced. There are three main problems to be solved.
Firstly, the method comprises the following steps: the electric element exists in the mold, and the mold is always in a temperature rise and temperature fall switching state, so that the slightly defective mold is likely to have defects such as cracks and the like, and the condition of electric leakage caused by water inflow of the mold is caused.
Secondly, the method comprises the following steps: because the mould itself is mostly the dysmorphism structure, and the heating pipe can not make the shape of handling mould dysmorphism structure, can fill a large amount of heat-conducting medium between event mould and the heating pipe, so the weight of single mould can increase at double, if mould weight increase back to the production water line, the production line can take place "indulge the car", "chain breakage" and so on abnormal state takes place, unless the bigger assembly line of new construction carrying power so equipment cost can sharply promote.
Thirdly, the method comprises the following steps: need heat drying after steeping the stoste in the product production process of flooding mould, the mould itself will have stoving temperature after the stoving finishes, need cool off the mould before the mould gets into next process, after the mould has inside heating pipe and has a large amount of heat conduction material of packing, whole root mould can lead to mould storage heat energy to promote by a wide margin (increase the range and reach 75% for the mould that does not have the filler) owing to material specific heat capacity problem, can consume more cooling energy consumption like this to the cooling, hardly reach energy saving and emission reduction's purpose.
Furthermore, at present, the dipping products such as condoms, finger cots or gloves are widely adopted in the heating mode outside the mould, because the individual difference of the physical strength performance index of the product glue film is too large, the probability of product damage or defect still has a certain proportion, about 2-5%, especially the condom product is related to the body health problem of users, and the problem is still solved.
