Description
Technical field
Belong to die temperance control field, be specifically related to the cooling structure that heat chews discharging opening.
Background technology
At present, in injection mould, the application of hot flow path is increasingly extensive, if but heat to chew cooling near discharging opening abundant not, face production in enormous quantities once product and be just easy to occur that heat chews the defective problem of product appearance band of discharging opening wire drawing and discharge outlet.For the cooling effect obtained, the following two kinds of structural designs of general employing realize the cooling that heat chews discharging opening: one is chew surrounding design one circle cooling circuit in heat, and this cooling circuit is chewed near heat as far as possible; Two is chew in heat to add cooling bushing between die, to be chewed cool by the cooling circuit in cooling bushing to heat.But above-mentioned two kinds of structural designs all can cause difficulty to the design of Cooling System of other parts on mould, and the second structural design also can have influence on the outward appearance of product.Cooling structure of the present invention design both can not affect the original cooling system structure design in other positions on mould, also can guarantee that the cooling effect that heat chews discharge outlet reaches better.
Summary of the invention
The object of the invention is exactly need good cooling effect for current mould cavity surface near the part of hot flow path, provide a kind of hot flow path cooling system mode, and structure is simple.
The object of the invention is by following technical scheme realize,
A kind of hot flow path cooling system, comprises heat and chews 1, solid plate 2, fixed mold core 3, product 4, chew surrounding be all designed with hot flow path cooling structure in heat.Its hot flow path cooling structure to be included on fixed mold core and solid plate heat and to chew two cooling water channels A, B that hot flow path axis both sides Parallel Symmetric arranges, and described two cooling water channels A, B are connected on die heater, so that cooling die die cavity and Re Zui simultaneously.Simultaneously, described hot flow path cooling structure is also included in two cooling wells C, D that heat on fixed mold core chews the Parallel Symmetric setting of hot flow path axis both sides, on solid plate, heat is provided with two cooling wells C1, D1 with chewing hot flow path axis both sides Parallel Symmetric, in described cooling well C, D, C1, D1, water-impermeable piece C5, D5, C5 is housed respectively ', D5 '.The cooling circuit that described two groups of cooling well C, D and C1, D1 are formed is received on the cold water pipes of constant temperature, so that actual conditions determine the constant temperature cold water flow passed into when producing according to injection moulding.
Beneficial effect of the present invention:
The hot flow path temperature that this structural design can chew discharging opening to heat is as required carried out stable and cools control reliably, eliminate discharging opening wire drawing and product appearance defect, and mould design and manufacture is easier.
accompanying drawing illustrates:
Fig. 1, Fig. 2 are the profiles that heat chews orthogonal both direction.
Fig. 3 is the partial perspective view of mutual structural relation between associate components in reflection Fig. 1 and Fig. 2.Wherein, 1 is that heat is chewed, and 2 is solid plate, and 3 is fixed mold core, and 4 is products.A and B is two cooling water channels on fixed mold core, and C is the cooling well on fixed mold core, is separated in cooling well by water-impermeable piece C5, and C1 is the well that solid plate is connected with cooling well C, is separated in cooling well C1 by water-impermeable piece C5 '.
Fig. 4 is the partial sectional view along I-I in Fig. 1.
Fig. 5 is the partial sectional view along II-II in Fig. 2.
detailed description of the invention:
Below in conjunction with Fig. 1 to Fig. 5, detailed description of the invention is described:
Fig. 1 and Fig. 2 shows profile mould being chewed axis direction two perpendicular longitudinal sections along heat, comprises heat and chews 1, solid plate 2, fixed mold core 3, product 4, water-impermeable piece C5, C5 ' and D5, D5 ', on fixed mold core, heat is chewed surrounding and is all designed with two groups of hot flow path cooling structures.
Fig. 3 reflects the partial perspective view of mutual structural relation between associate components in Fig. 1 and Fig. 2.Wherein, 1 is that heat is chewed, and 2 is solid plate, and 3 is fixed mold core, and 4 is products.A and B is two cooling water channels on fixed mold core, and C is the cooling well on fixed mold core, is separated in cooling well by water-impermeable piece C5, and C1 is the well that solid plate is connected with cooling well C, is separated in cooling well C1 by water-impermeable piece C5 '.Composition graphs 1 and Fig. 2 understand further, on fixed mold core, heat is chewed axis opposite side and is paralleled position with cooling well C and be also provided with another and cool well D, also be provided with another and cool well D1 chewing axis opposite side with heat on cooling well the D connected and parallel solid plate that is placed in, cool in well D1 and separated by water-impermeable piece D5 '.
As shown in Figure 1, on fixed mold core and solid plate, heat is chewed hot flow path axis both sides Parallel Symmetric and is provided with two cooling water channels A, B.
In Fig. 1, cooling water channel B, along the partial sectional view of I-I, comprises solid plate 2 as shown in Figure 4, fixed mold core 3, water pipe 9, die heater 10, cooling water channel B, and the cooling water channel B in described Fig. 1 is connected on die heater 10 by water pipe 9.To have said structure identical with cooling water channel B, and cooling water channel A is also connected on die heater 10 by corresponding water pipe 9, so that cooling die die cavity and Re Zui simultaneously.
As shown in Figure 2, on fixed mold core, heat chews two cooling wells C, D that hot flow path axis both sides Parallel Symmetric is arranged, on solid plate, heat is provided with two cooling wells C1, D1 with chewing hot flow path axis both sides Parallel Symmetric, in two water holes of described cooling well C, D, water-impermeable piece C5, D5 is housed respectively.
Well C1, D1 partial sectional view along II-II is cooled as shown in Figure 5 in Fig. 2, comprise solid plate 2, be arranged at cooling well C1, the D1 on solid plate, in two water holes of described cooling well C1, D1, water-impermeable piece C5 ', D5 ' are housed respectively, two cooling wells that cooling well C1, D1 are formed are concatenated into loop via water hole E and are connected on the cold water pipes of cold water circulating system 8 of constant temperature via water pipe 6,7, so that actual conditions determine the constant temperature cold water flow passed into when producing according to injection moulding.Due to water-impermeable piece C5, C5 ' and D5, D5 ' effect, in cooling well C, D, C1, D1, water-impermeable piece both sides cold water flows to different and forms the loop of series connection, and the cold water of constant temperature can arrive heat and chew near discharging opening.When injection moulding is produced, can determine whether open this cooling circuit according to actual conditions, and the size of the cold water flow passed into.In addition, described cooling water channel A, B longitudinal section is mutually vertical with described cooling well C, D longitudinal section, so just fully guarantees and effectively improves the surrounding of cooling effect hot flow path cooling structure chews to(for) heat.
In addition to the implementation, the present invention can also adopt other embodiments, and all employings are equal to the technical scheme that replacement or equivalent transformation are formed, within the protection domain all dropping on application claims.
