Description
Technical field
The utility model belongs to mould manufacturing field, is related to the hot runner cooling device of notebook mold.
Background technique
With extensive use of the hot runner technology in plastic mould, which save also save while a large amount of runner scraps
Production cost, improves the production efficiency of enterprise.But due at hot runner gum-injecting port temperature it is excessively high, hot nozzle discharge outlet is cold
Insufficient, it is easy to generate defect in sizing material forming process, easily occurs burn, shrinkage depression is atomized etc. at molding product glue-feeder
Defect seriously affects the appearance of product.Simultaneously because steel thermal coefficient is higher, temperature is excessively high to also result in entire mold temperature
Raising, performance and entire mold cooling system to mould steel put forward higher requirements, currently, solving hot runner gum-injecting port temperature
Spend high method mainly reduces gum-injecting port and neighbouring temperature by way of adding cooling water channel outside hot runner.
Since hot glue channel temp is higher (280 degree~320 degree or so), the common type of cooling is due to the cooling water channel on mode
Depth is shallower, if merely deepen depth will lead to cooling water circulation it is unsmooth, have stagnant water phenomenon, cannot fast and effectively reduce
Mold temperature lengthens so as to cause the molding cycle of product, and production efficiency reduces.
Utility model content
In view of this, the utility model is inadequate in order to solve cooling water channel depth, mold temperature cannot be fast and effectively reduced
The problem of spending provides one kind and is suitable for notebook mold, can deepen cooling water channel depth and not will lead to cooling water stagnant water
Hot runner cooling device.
In order to achieve the above objectives, the utility model provides the following technical solutions: the hot runner cooling device of notebook mold,
Including mother module core, the cylindric hot runner that injection molding liquid passes through is provided in mother module core, hot runner lower inside is provided with nozzle, heat
The outer wall of Jiao Dao is provided with cooling water channel, and cooling water channel depth is 75%~98% of the length on hot runner direction, cooling water
Annular insert engaged therewith is plugged with inside road, the depth of annular insert is the 55%~75% of cooling water channel depth.
Optionally, cooling water channel is provided with columned inlet and outlet, is separately positioned on annular cooling water road
Two ports.
Optionally, the section of cooling water channel is that 2/3 is round, semi-circular or 1/3 is round.
Optionally, the tensile elongation in annular insert section is less than cooling water channel section tensile elongation, and annular insert is not kept off
The firmly water inlet and water outlet of cooling water channel.
Optionally, the upper surface of cooling water channel is provided with two ring packing ring recess, mold insert upper surface be provided with one at
The ring type seal of type.
Optionally, the minimum range between cooling water channel and hot runner is 2.5mm.
The utility model has the beneficial effects that: the back side increases ring-like mold insert and blocks one section by cooling water channel depth down,
Cooling water control is allowed in a certain range, so that maintaining water flowing while increasing cooling effect having deepened cooling water channel
More unimpeded, cooling velocity is very fast, so that entire mode ontology is cooling uniformly, temperature equalization, reduces mode ontology
Deformation, improves product surface garland phenomenon, improves product quality, shorten the molding cycle of product, improves production effect
Rate.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the hot runner cooling device overall structure front view of the utility model notebook mold；
Fig. 2 is the hot runner cooling device partial top view of the utility model notebook mold.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Appended drawing reference in Figure of description include: mother module core 1, hot runner 2, nozzle 3, annular insert 4, cooling water channel 5,
Water inlet 6, water outlet 7, ring type seal 8.
2 cooling device of hot runner of notebook mold as shown in Figs. 1-2, including mother module core 1 are provided in mother module core 1
The cylindric hot runner 2 that injection molding liquid passes through, 2 lower inside of hot runner are provided with nozzle 3, and the outer wall of hot runner 2 is provided with cooling
Water route 5, cooling water channel 5 are provided with columned water inlet 6 and water outlet 7, are separately positioned on two ends on annular cooling water road 5
Mouthful, the section of cooling water channel 5 is that 2/3 is round, semi-circular or 1/3 is round, and 5 depth of cooling water channel is the length on 2 direction of hot runner
The 75%~98% of degree is plugged with annular insert 4 engaged therewith inside cooling water channel 5, and the tensile elongation in 4 section of annular insert is small
In 5 section tensile elongation of cooling water channel, and annular insert 4 does not block the water inlet 6 and water outlet 7 of cooling water channel 5, annular edge
The depth of part 4 is the 55%~75% of 5 depth of cooling water channel, and the upper surface of cooling water channel 5 is provided with two ring packing ring recess,
4 upper surface of annular insert is provided with integrally formed ring type seal 8, and in use, annular insert 4 can be realized preferably
Disassembly and sealing.
Annular insert 4 in use, is first filled in 5 the inside of cooling water channel by the utility model, close through ring type seal 8
It is honored as a queen, by injecting cooling water to water inlet 6, cooling water is flowed in cooling water channel 5, through cooling water in annular water channel
It circulates, takes away the heat of the generation of hot runner 2, constantly to achieve the purpose that uniformly to be quickly cooled down hot glue road 2.
By the way that by 5 depth down of cooling water channel, the back side increases ring-like mold insert and blocks one section, allow cooling water control in certain model
In enclosing, so that having deepened cooling water channel 5, it is more unimpeded to maintain water flowing while increasing cooling effect, cooling velocity compared with
Fastly, so that the cooling uniform, temperature equalization of entire mode ontology, reduces the deformation of mode ontology, improve product surface
Garland phenomenon, improves product quality, shortens the molding cycle of product, improves production efficiency.
