A hot glue way cooling structure, its includes go up mould benevolence subassembly, the last mould benevolence subassembly of includes the merciful and peaceful shaping mold insert of mould, shaping mold insert install in upward in the mould benevolence, shaping the shaping face with shaping mold insert going up mould benevolence encloses to close and forms the shaping chamber of product, upward installs the runner cover in the mould benevolence, is equipped with hot runner, its characterized in that in the runner cover: being equipped with in the runner cover around the hot runner along with shape cooling water course, be equipped with water inlet and delivery port along with shape cooling water course in the runner cover, it has the cooling water to lead to in the cooling water course, cooling water course and minimum distance between the hot runner internal surface be 2.5mm, the bottom surface of runner cover is cooled off water course and the top minimum distance between shaping and is 3mm for the take shape top face of taking shape in chamber of product.
Description
Technical field
The utility model relates to plastic mould field, especially relates to the flow passage system of plastic mould, is specially a kind of hot runner cooling structure.
Background technology
Along with the extensive use of hot runner technology in plastic mould, when having saved a large amount of runner scrap, it also saves production cost, improve the production efficiency of enterprise. But due to hot runner gum-injecting port place excess Temperature, it is cooling insufficient that heat is chewed discharging opening place, is easy to produce defect in sizing material forming process, the product glue-feeder place of moulding be prone to burn, the defect such as shrinkage depression atomization, have a strong impact on the outward appearance of product. Because steel thermal conductivity factor is higher, excess Temperature also can cause the rising of whole mold temperature simultaneously, and the performance to mould steel and whole mold cooling system propose higher requirement.
At present, the method that solves hot runner gum-injecting port excess Temperature mainly by add outward at hot runner the mode of cooling water channel reduce gum-injecting port and near temperature, notification number is that the Chinese utility model patent of CN202702558U has been announced a kind of hot flow path cooling device, it is, on heat is chewed, coolant jacket is installed, on coolant jacket, be connected with pipeline, by the cooling water circulating in pipeline, heat is chewed and carried out local cooling, its pipeline that is connected with cooling water is made up of with the annulus line of being located at coolant jacket periphery the linear pipeline that runs through die, because annulus line is only arranged on the periphery of coolant jacket, therefore the glue-feeder that whole pipeline exists distance heat to chew is far away, to the glue-feeder shortcoming of cooling effect inequality around, although by adopting the good copper coolant jacket of radiating effect can improve the cooling effect that heat is chewed, still fundamentally do not solve the even problem of glue-feeder inhomogeneous cooling, notification number is that the Chinese utility model patent of CN201597168U has been announced a kind of hot runner cooling water channel, it is assembled by the water jacket docking that is arranged at the fixed cover in caster and be arranged in mother module core, its outer peripheral face at water jacket is provided with annular water route groove and realizes sealing by ring packing ring recess, thereby the cooling water leakage in anti-water-baffling sleeve, but it still exists the problem that annular water route is easily revealed, easily got rusty in actual use, thereby affect the service life of mould.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hot runner cooling structure, and it can solve the problem that cooling effect is inhomogeneous, sealing is poor that existing hot runner cooling structure exists.
Its technical scheme is, a kind of hot runner cooling structure, it comprises upper cores assembly, described upper cores assembly comprises upper cores and shaping mold insert, described shaping mold insert is installed in described upper cores, the forming face of the forming face of described upper cores and shaping mold insert encloses and forms product shaping chamber, in described upper cores, sprue bush is installed, in described sprue bush, be provided with hot flow path, it is characterized in that: in described sprue bush, be provided with the conformal cooling channel around described hot flow path, in described sprue bush, be provided with water inlet and the delivery port of described conformal cooling channel, in described cooling water channel, be connected with cooling water, minimum range between described cooling water channel and described hot flow path inner surface is 2.5mm, the bottom surface of described sprue bush is top formed of described product shaping chamber, minimum range between described cooling water channel and described top formed is 3mm.
Further, it is integrally formed that described sprue bush adopts laser sintered technology.
Further, in described upper cores, shaping mold insert, all have cooling water channel.
Compare with the cooling structure of existing hot runner, the beneficial effects of the utility model are: in its sprue bush, be provided with the conformal cooling channel around hot flow path, by logical cooling water in this conformal cooling channel, hot flow path is cooled, because it is conformal cooling channel, thereby can carry out hot flow path cooling equably, be that 2.5mm has also reduced the distance between cooling water and hot flow path greatly simultaneously by the minimum range between cooling water channel center line and hot flow path, more ensured cooling effect; In addition, sprue bush bottom surface is top formed of product shaping chamber, thereby makes sprue bush have the effect of product shaping concurrently simultaneously, has effectively saved mold materials and cost; Sprue bush adopts laser sintered technology integrally formed, has effectively avoided the leakage problem of cooling water in cooling water channel, has also guaranteed the shaping processing of conformal cooling channel in sprue bush; The heat that is delivered in addition product can be by the timely cooling heat dissipation of cooling water channel of opening respectively in upper cores, shaping mold insert, more guarantee the Quick uniform cooling of hot flow path, thereby more effectively avoid gum-injecting port shrinkage depression, the atomization that product causes because of inhomogeneous cooling and the defect such as burn, especially more obvious to the effect of the high perspex heavy wall product of quality requirement.
