Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention will be further described.
In embodiment as shown in Figure 1, a kind of mold cooling system, comprise core holder 2 and be embedded the core 1 on core holder, for ease of processing and manufacturing, core is formed by the body portion 11 be fixed on core holder with for shaping bossing 12 usually, the bottom surface of fitting at body portion and the core holder of core arranges cavity 13, core holder cavity position in correspondence then arranges lower cavity 21, upper cavity is embedded establishes a boundling refrigerating seat 3 extending to lower cavity bottom surface, that is, boundling refrigerating seat fits in by upper, in the closed cavity that lower cavity is formed.What cooling core of the present invention adopted is cooling shaft structure, with existing cooling shaft structure unlike, cooling shaft is made up of the upper cooling shaft 14 be arranged in cylindricality in core and the lower cooling shaft 22 that to be arranged on boundling refrigerating seat corresponding upper cooling shaft position, be understandable that, upper cooling shaft extends to the top of core bossing from the upper cavity bottom surface of core, and upper and lower cooling shaft is preferably cylindrical, to facilitate processing.In addition, a coaxial fixing hole is set in lower cooling shaft bottom surface, the cooling tube 4 extending to cooling shaft is set in fixing hole, and between cooling tube and upper and lower cooling shaft, there is uniform gap, thus between cooling tube and upper and lower cooling shaft, form the pipelined channel 5 of a tubulose, certainly, cooling tube should adopt pipe, can guarantee the pipelined channel uniformity between cooling tube and upper and lower cooling shaft like this, cooling tube is fixed in fixing hole by the mode of interference fit.Further, the inlet pipeline 33 that is communicated with cooling tube endoporus also need be set in boundling refrigerating seat and the outlet pipeline 34 of cooling shaft under being communicated with, between core and boundling refrigerating seat, be positioned at upper and lower cooling shaft joint arranges cooling water seal structure, to realize the sealing between upper and lower cooling shaft simultaneously.Operationally, cooling water enters into the endoporus of cooling tube by inlet pipeline to mould, then flows out from the top of cooling tube and enters in pipelined channel, flow out the cooling completed core finally by outlet pipeline.
It should be noted that, gap should be left between the top of cooling tube and the bottom surface of upper cooling shaft, so that the smooth flow of cooling water, certainly, in order to be conducive to the fixing of cooling tube, we also can arrange a locating hole in the bottom surface of upper cooling shaft as illustrated in fig. 3, make the top of cooling tube fit in locating hole simultaneously, and be disposed radially some apopores 41 at cooling tube sidewall near top end, apopore is in cooling tube sidewall decile layout ringwise, thus cooling tube two ends are located, and cooling water can flow out from apopore.In addition, as shown in Figure 3, cooling tube can adopt composite construction, its internal layer is metal tube 42, and skin is rubber tube 43, and centre is thermal insulation layer 44, metal tube can be made with stainless steel tube, and rubber tube can adopt silicon rubber to make, and thermal insulation layer can adopt polyurethane foam plastics.Due to, polyurethane foam plastics has good effect of heat insulation, therefore can effectively stop the cooling water of high temperature in pipelined channel to be again delivered in cooling tube by heat.
In order to improve the turbulence level of cooling water, we can arrange at the lateral surface of cooling tube the triangular sawtooth ring 45 arranged vertically, and make triangular sawtooth ring be less than the included angle B between triangular sawtooth ring another side and cooling tube cross section near the included angle A between the side of boundling refrigerating seat and cooling tube cross section, preferably, included angle A can between 0 degree to 15 degree, and included angle B can between 60 degree to 75 degree, like this, both the flow resistance reducing cooling water had been conducive to, the cross section of cooling water its flowing after the peak through triangular sawtooth ring simultaneously has an increase rapidly, thus be conducive to the turbulence level improving cooling water.
Existing cooling shaft formula cooling structure adopts separately O type circle to seal usually, because the temperature of mold work is very high, particularly for the mould of compression mod one class, O type circle easily lost efficacy after bearing high temperature for a long time, in order to improve sealing effectiveness and persistence, as shown in Figure 2, cooling water seal structure of the present invention comprises inner seal ring groove 31 outside the lower cooling shaft being arranged on boundling refrigerating seat coaxially and external seal annular groove 32, sealing copper ring 6 is set in inner seal ring groove, O type circle 7 is set in external seal annular groove, to realize soft, hard dual-seal.Because the high-temperature cooling water that may ooze out from sealing copper ring is extremely micro-, and the pressure of cooling water is minimum, therefore significantly reduces the requirement of the sealing property to O type circle.The cross section of sealing copper ring is the isosceles trapezoid of traverse, and the height of sealing copper ring progressively reduces from the inside to the outside, the inclined-plane, both sides up and down of sealing copper ring then arranges some coaxial band saw teeth groove 61, angle between the inclined-plane, both sides up and down of sealing copper ring can between 1 degree to 2 degree, certainly, height outside sealing copper ring can equal the degree of depth of inner seal ring groove, thus make the height of the inner side of sealing copper ring be greater than the degree of depth of inner seal ring groove, and sealing copper ring preferably adopts red copper to make, like this, the pressure between core and boundling refrigerating seat is relied on after assembling, the upper and lower side crimp of sealing copper ring, thus form the sealing ring of multiple tracks densification, and the deformation extent of per pass sealing ring progressively reduces from the inside to the outside, thus the upper and lower side plastic deformation completely sealing copper ring can be avoided, to guarantee that it has permanent sealing effectiveness.
As shown in Figure 1 in order to improve the stability of cooling tube further, we can on cooling tube sheathed at least two elastic clamp rings 8, be preferably two, and the middle part of cooling tube should be arranged on as far as possible.As shown in Figure 4, elastic clamp ring ovalize, thus there is a long axis direction and a short-axis direction, elastic clamp ring adopts spring steel wire to make, the dual-side place of the corresponding major axis of elastic clamp ring arranges outside bullet pin 81 respectively, and play pin should to boundling refrigerating seat lopsidedness.In addition, the dual-side of elastic clamp ring short-axis direction is flexibly squeezed on the lateral wall of cooling tube, and the difference between the long and short axle that distance between the outer end points that two play pins and the difference between the diameter of upper cooling shaft should be more than or equal to elastic clamp ring, like this, as shown in Figure 5, when cooling tube enters in upper cooling shaft, two play the extruding that pin is subject to cooling shaft sidewall, the long axis direction contraction distortion making elastic clamp ring original is called minor axis, and cooling tube is clamped, original short-axis direction then expands outwardly becomes major axis.Be understandable that, two elastic clamp rings should be arranged vertically mutually, thus make cooling tube obtain clamping position in two directions simultaneously.
As shown in Figure 1, the layout in boundling refrigerating seat for the ease of inlet pipeline and outlet pipeline, it is avoided mutually to produce interference, inlet pipeline 33 comprises and is somely arranged on boundling refrigerating seat side and the horizontal house steward 331 of the water inlet of lateral arrangement, and be arranged on the bottom surface and the longitudinal house steward 332 of the water inlet be communicated with one of them horizontal house steward of intaking extending longitudinally that boundling refrigerating seat and lower cavity fit, the horizontal house steward of each water inlet intersects connection mutually, and the horizontal house steward of one of them water inlet through cooling tube axis is communicated with this cooling tube endoporus port, that is, horizontal house steward of intaking just should fix the fixing hole lower end of cooling tube through lower cooling shaft bottom surface in the position of boundling refrigerating seat short transverse, the cooling tube being fixed on fixing hole upper end can be made like this to be connected with the horizontal house steward of water inlet.With inlet pipeline analogously, outlet pipeline 34 comprises and is somely arranged on boundling refrigerating seat side and the horizontal house steward 341 of the water outlet of lateral arrangement and be arranged on the bottom surface and the water outlet longitudinal direction house steward 342 be communicated with one of them water outlet transverse direction house steward extending longitudinally that boundling refrigerating seat and lower cavity fit, the horizontal house steward of each water outlet intersects connections mutually, and the horizontal house steward of one of them water outlet passes lower cooling shaft thus is communicated with this lower cooling shaft side.Like this, in boundling refrigerating seat, form the connection pipe network of the horizontal house steward of water inlet and the connection pipe network of the horizontal house steward of water outlet respectively, and two pipe networks are in different aspects in the short transverse of boundling refrigerating seat, thus form hierarchy, and it can be avoided mutually to interfere.It should be noted that, the horizontal house steward of water-in and water-out can be blind hole, the horizontal house steward of water-in and water-out simultaneously arranges copper seal plug 9 at the external port place of boundling refrigerating seat, and be positioned at the longitudinal house steward place of water-in and water-out in the bottom surface that boundling refrigerating seat and core holder are fitted and cooling water containment member is set, be understandable that, cooling water containment member herein can adopt the sealing copper ring identical with aforementioned cooling water seal structure and O type circle.Further, the external port of the horizontal house steward of water-in and water-out is conical bore, correspondingly, as shown in Figure 6, seal plug is truncated cone, and at the lateral surface of seal plug, the triangular sawtooth annular groove 91 arranged vertically is set, seal plug by extruding mode close-fitting in external port to form sealing.Further, outside seal plug, the large end face held arranges cone-shaped groove, and in cone-shaped groove, be embedded the expansion core 92 of a hard.Like this, when the extruding force between Long-Time Service seal plug and external port reduces and occurs infiltration, by knocking expansion core, seal plug is expanded, thus recover its sealing effectiveness.Particularly, when the bossing profile of core moulding is larger, we need to arrange multiple cooling shaft to make core be cooled fully.As shown in Figure 7, each cooling shaft should preferably adopt rectangular array mode to arrange, namely cooling shaft embark on journey, layout in column, and should be mutually vertical between row and column.Now, horizontal house steward 331 of water inlet can simultaneously through the cooling tube axis in a row or column cooling shaft, and is connected with the endoporus port of this row maybe this row cooling tube 4 respectively; Analogously, a horizontal house steward 341 of water outlet can simultaneously through cooling 22 well sides under a row or column thus being connected with cooling shaft under this row maybe these row, like this, cooling water is diverted to the horizontal house steward of each water inlet after the longitudinal house steward 332 of water inlet enters, then be diverted to by the horizontal house steward of water inlet in the cooling tube of each row or each row, cooling water in the cooling tube of each row or each row is flowed in the horizontal house steward of water outlet of each row or each row by lower cooling shaft again after pipelined channel, finally, the cooling water of the horizontal house steward of each water outlet is flowed to the longitudinal house steward of water outlet again.
Finally, as shown in Figure 1, we also need arrange the inlet channel 23 be communicated with the longitudinal house steward of water inlet and the outlet conduit 24 be communicated with the longitudinal house steward of water outlet on core holder, and are provided with water pipe head 25 at the external port place of water-in and water-out pipeline.When water pipe head needs the side being positioned at core holder, inlet channel can be arranged on lower cavity bottom surface and the corresponding longitudinal water pipe hole of the longitudinal house steward of water inlet by one and be arranged on core holder side and the horizontal water pipe hole be communicated with longitudinal water pipe hole is formed, and water pipe head is then fixed in the external port in horizontal water pipe hole.Analogously, outlet conduit also can be made up of longitudinal water pipe hole and horizontal water pipe hole, longitudinal water pipe hole is wherein arranged on the longitudinal house steward of lower cavity bottom surface and water outlet to corresponding position, horizontal water pipe hole is then similarly arranged on core holder side and is communicated with longitudinal water pipe hole, and water pipe head is fixed in the external port in horizontal water pipe hole.When water pipe head needs the bottom surface being positioned at core holder, directly can arrange in the longitudinal house steward position of core holder bottom surface correspondence water-in and water-out the longitudinal water pipe hole being communicated with the longitudinal house steward of water-in and water-out, water pipe head is fixed in the external port in longitudinal water pipe hole; Or on the basis of last scheme, longitudinal water pipe hole that one is communicated with horizontal water pipe hole is set in core holder bottom surface again, water pipe head is fixed in the external port in this longitudinal water pipe hole, and certainly, the external port in horizontal water pipe hole wherein goes out to arrange corresponding seal plug.
