Description
Technical field
The utility model belongs to injection machine field, especially relates to a kind of heating, cooling injection machine circulation.
Background technology
In injection moulding, the temperature of mould directly has influence on quality and the production efficiency of goods.Because the performance of various plastics requires different with moulding process, also different to the requirement of mold temperature.The temperature being generally expelled to plastics in mould is about 200-300 DEG C, after melt is solidified into goods, when mold temperature is lower time, the demoulding is carried out to goods, the reduction of mold temperature mainly relies in mould and passes into cooling medium, taken away by heat, the cool time of injection mould depends primarily on the cooling effect of cooling system.According to statistics, account for 2/3 of the whole infusion cycles cycle cool time of mould, the cool time therefore shortening infusion cycles cycle mould is the key of enhancing productivity.Current to mold cools down method more be cooled with circulating water, when mold cools down require higher time usually adopt cooling-water machine to cool.
After some plastic grain raw material is created, expose in atmosphere, particle surface has condensed the moisture in air, in HTHP forming process, when moisture evaporates in the appearance barrel closed and mould, the space that formation density differs in size, color, Density inhomogeneity, cause the product quality processed defective, for this kind of plastics, before the forming must heat drying.Current to plastic drying method more a drying machine is set separately, utilize electric heater to be assigned to evaporation plastics moisture by heat, plastic heating is dry.
The cooling of prior art and material drying device mainly contain following shortcoming: (1), mold cools down and dry materials are two cover autonomous systems, and a set of is refrigeration system, and another set of is heating system, and two cover systems do not have Combinatorial Optimization; (2), cooling system service time of a specified duration after, the solid deposits in water is easy fouling in the cooling circuit of mould, reduce heat transfer efficiency, cause thermal loss; (3), cooling die time, the temperature of water will raise, and mould water in-out port exists certain temperature difference, easily produces temperature and controls uneven and cause quality of item to decline; (4), the amount of heat of cooling water absorption mould is not fully used; (5), when dry materials, as dry in adopted open type, the humid air with higher temperature is directly discharged, the energy is not fully used, adopt the closed cycle not with dehumidification function dry, circulating air has higher humidity all the time, and it is not obvious that psychrometric difference imported and exported by hopper, and its drying effect is also undesirable.
