The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and the specific embodiment.
Among the embodiment as shown in Figure 1, a kind of mold cooling system, comprise core holder 2 and the core 1 that is embedded on the core holder, for ease of processing and manufacturing, core is made of the bossing 12 that is fixed on the body portion 11 on the core holder and is used for moulding usually, the bottom surface of fitting at body portion and the core holder of core arranges cavity 13, core holder cavity position on correspondence then arranges lower cavity 21, upper cavity is embedded establishes a boundling refrigerating seat 3 that extends to lower cavity bottom surface, that is to say, the boundling refrigerating seat fits in by upper, in the sealing cavity that lower cavity consists of.What cooling core of the present invention adopted is the cooling shaft structure, different with existing cooling shaft structure is, cooling shaft is made of the lower cooling shaft 22 that is arranged on the upper cooling shaft 14 that is cylindricality in the core and is arranged on the 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, with convenient processing.In addition, in lower cooling shaft bottom surface a coaxial fixing hole is set, the cooling tube 4 that extends to cooling shaft is set in the fixing hole, and between cooling tube and upper and lower cooling shaft, has uniform gap, thereby form the pipelined channel 5 of a tubulose between cooling tube and upper and lower cooling shaft, certainly, cooling tube should adopt pipe, can guarantee like this pipelined channel uniformity between cooling tube and the upper and lower cooling shaft, cooling tube can be fixed in the fixing hole by the mode of interference fit.Further, also need in the boundling refrigerating seat, to arrange the inlet pipeline 33 that is communicated with the cooling tube endoporus and be communicated with under the outlet pipeline 34 of cooling shaft, simultaneously between core and boundling refrigerating seat, be positioned at upper and lower cooling shaft joint cooling water seal structure is set, to realize the sealing between the upper and lower cooling shaft.Mould is when work, and cooling water is entered into the endoporus of cooling tube by inlet pipeline, then flows out from the top of cooling tube to enter in the pipelined channel, flows out the cooling of having finished core finally by outlet pipeline.
Need to prove, should leave the gap between the top of cooling tube and the bottom surface of upper cooling shaft, so that flowing smoothly of cooling water, certainly, in order to be conducive to the fixing of cooling tube, we also can arrange a locating hole as illustrated in fig. 3 in the bottom surface of upper cooling shaft, the top of cooling tube is fitted in the locating hole, and be disposed radially some apopores 41 at the cooling tube sidewall near top end, apopore the cooling tube sidewall ringwise five equilibrium arrange, thereby make location, cooling tube two ends, 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 the 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.Because polyurethane foam plastics has good effect of heat insulation, therefore can effectively stop the cooling water of high temperature in the pipelined channel that heat is delivered in the cooling tube again.
In order to improve the turbulence level of cooling water, the triangle saw-tooth ring 45 that we can arrange vertically in the lateral surface setting of cooling tube, and make the triangle saw-tooth ring near the side of boundling refrigerating seat and the included angle A between the cooling tube cross section less than the included angle B between triangle saw-tooth ring another side and the cooling tube cross section, preferably, included angle A can be at 0 degree between 15 degree, and included angle B can be at 60 degree between 75 degree, like this, both be conducive to reduce the flow resistance of cooling water, cooling water its cross section that flows behind the peak of process triangle saw-tooth ring has an increase rapidly simultaneously, thereby is conducive to improve the turbulence level of 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 and the external seal annular groove 32 in the lower cooling shaft outside that is arranged on coaxially the boundling refrigerating seat, sealing copper ring 6 is set in the inner seal ring groove, O type circle 7 is set, soft to realize, hard dual-seal in the external seal annular groove.Because extremely micro-from the high-temperature cooling water that the sealing copper ring may ooze out, and the pressure of cooling water is minimum, has therefore greatly reduced the requirement to the sealing property of 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, on the inclined-plane, up and down both sides of sealing copper ring some coaxial band saw teeth groove 61 are set then, angle between the inclined-plane, up and down both sides of sealing copper ring can be at 1 degree between 2 degree, certainly, the height in the sealing copper ring outside can equal the degree of depth of inner seal ring groove, thereby make the height of the inboard that seals copper ring greater than the degree of depth of inner seal ring groove, and the sealing copper ring preferably adopts red copper to make, like this, rely on the pressure between core and the boundling refrigerating seat after the assembling, the up and down side crimp of sealing copper ring, thereby the sealing ring of formation multiple tracks densification, and the deformation extent of per pass sealing ring progressively reduces from the inside to the outside, thereby can avoid sealing the completely plastic deformation of up and down side of copper ring, have permanent sealing effectiveness to guarantee it.
As shown in Figure 1 in order further to improve the stability of cooling tube, we can be on cooling tube sheathed at least two elastic clamp rings 8, be preferably two, and should be arranged on the middle part of cooling tube as far as possible.As shown in Figure 4, the elastic clamp ring ovalize, thus a long axis direction and a short-axis direction had, and elastic clamp ring adopts spring steel wire to make, the dual-side place of the corresponding major axis of elastic clamp ring arranges respectively outside bullet pin 81, and the bullet pin should be to boundling refrigerating seat lopsidedness.In addition, the dual-side of elastic clamp ring short-axis direction flexibly is squeezed on the lateral wall of cooling tube, and the difference between the diameter of the distance between two outer end points that play pins and upper cooling shaft should be more than or equal between the long and short axle of elastic clamp ring poor, like this, as shown in Figure 5, in the time of in cooling tube enters into upper cooling shaft, two play the extruding that pin is subject to the cooling shaft sidewall, make the original long axis direction contraction distortion of elastic clamp ring be called minor axis, and cooling tube clamped, original short-axis direction then expands outwardly becomes major axis.Be understandable that, two elastic clamp rings should be arranged vertically mutually, thereby make cooling tube obtain simultaneously clamping position in two directions.
As shown in Figure 1, the layout in the boundling refrigerating seat for the ease of inlet pipeline and outlet pipeline, avoid it mutually to produce interference, inlet pipeline 33 comprises some horizontal house stewards 331 of water inlet that are arranged on boundling refrigerating seat side and lateral arrangement, and be arranged on the vertical house steward 332 of water inlet that bottom surface that boundling refrigerating seat and lower cavity fit and longitudinal extension are communicated with one of them horizontal house steward of intaking, each horizontal house steward of intaking is intersected connection mutually, and one of them horizontal house steward of water inlet who passes the cooling tube axis is communicated with this cooling tube endoporus port, that is to say, the horizontal house steward of intaking should just pass the fixedly fixing hole lower end of cooling tube, lower cooling shaft bottom surface in the position of boundling refrigerating seat short transverse, and the cooling tube that is fixed on the fixing hole upper end is connected with the horizontal house steward of water inlet.With the similar ground of inlet pipeline, outlet pipeline 34 comprises and somely is arranged on the horizontal house steward 341 of water outlet of boundling refrigerating seat side and lateral arrangement and is arranged on bottom surface that boundling refrigerating seat and lower cavity fit and the vertical house steward 342 of water outlet that longitudinal extension is communicated with the horizontal house steward of one of them water outlet, the horizontal house steward of each water outlet is intersected connection mutually, thereby and the horizontal house steward of one of them water outlet pass lower cooling shaft and be communicated with this time cooling shaft side.Like this, in the boundling refrigerating seat, form respectively the horizontal house steward's of water inlet connection pipe network and the horizontal house steward's of water outlet connection pipe network, and two pipe networks are in different aspects in the short transverse of boundling refrigerating seat, thereby form hierarchy, can avoid it mutually to interfere.Need to prove, the horizontal house steward of water-in and water-out can be blind hole, the horizontal house steward of simultaneously water-in and water-out arranges copper seal plug 9 at the external port place of boundling refrigerating seat, and be positioned at the vertical house steward of water-in and water-out place in the bottom surface of boundling refrigerating seat and the applying of core holder the 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 horizontal house steward's of water-in and water-out external port is conical bore, correspondingly, as shown in Figure 6, seal plug is truncated cone, and at the triangle sawtooth annular groove 91 that the lateral surface setting of seal plug is arranged vertically, seal plug can seal to form in external port by the mode close-fitting of extruding.Further, on the end face of the large end in the seal plug outside cone-shaped groove is set, and in cone-shaped groove, is embedded the expansion core 92 of a hard.Like this, when the extruding force between long-term use seal plug and the external port reduces and infiltration occurs, can seal plug be expanded by knocking expansion core, thereby recover its sealing effectiveness.Particularly, when the bossing profile of core moulding was larger, we need to arrange a plurality of cooling shafts in order to core is cooled off fully.As shown in Figure 7, each cooling shaft should preferably adopt the rectangular array mode to arrange, and namely cooling shaft embarks on journey, becomes row to arrange, and should be mutually vertical between the row and column.At this moment, the horizontal house steward 331 of water inlet can pass cooling tube axis in a row or column cooling shaft simultaneously, and respectively with this row maybe the endoporus port of this row cooling tube 4 be connected; Similar ground, thereby horizontal house steward 341 of water outlet can pass simultaneously under a row or column cooling 22 well sides and this row maybe this row time cooling shaft be connected, like this, cooling water is diverted to the horizontal house steward of respectively intaking after vertical house steward 332 of intaking enters, then be diverted in the cooling tube of each row or each row by the horizontal house steward of water inlet, cooling water in the cooling tube of each row or each row is through being flowed among the horizontal house steward of water outlet of each row or each row by lower cooling shaft behind the pipelined channel again, at last, the horizontal house steward's of each water outlet cooling water is flowed to the vertical house steward of water outlet again.
At last, as shown in Figure 1, we also need at the core holder inlet channel 23 that is communicated with the vertical house steward of water inlet and the outlet conduit 24 that is communicated with the vertical house steward of water outlet to be set, and are provided with water pipe head 25 at the external port place of water-in and water-out pipeline.When water pipe head need to be positioned at the side of core holder, inlet channel can be arranged on lower cavity bottom surface and the corresponding vertical water pipe hole of the vertical house steward of water inlet and be arranged on core holder side and the horizontal water pipe hole that is communicated with vertical water pipe hole consists of by one, and water pipe head then is fixed on the external port in horizontal water pipe hole.Similar ground, outlet conduit also can be made of vertical water pipe hole and horizontal water pipe hole, vertical water pipe hole wherein is arranged on lower cavity bottom surface and the vertical house steward of water outlet to the corresponding position, laterally the water pipe hole then similarly is arranged on core holder side and is communicated with vertical water pipe hole, and water pipe head is fixed on the external port in horizontal water pipe hole.When water pipe head need to be positioned at the bottom surface of core holder, can directly in the vertical house steward of correspondence water-in and water-out position, core holder bottom surface the vertical water pipe hole that is communicated with the vertical house steward of water-in and water-out be set, water pipe head is fixed on the external port in vertical water pipe hole; Perhaps on the basis of last scheme, vertical water pipe hole that is communicated with horizontal water pipe hole is set in core holder bottom surface again, water pipe head is fixed on the external port in this vertical water pipe hole, and certainly, the external port in horizontal water pipe hole wherein goes out corresponding seal plug need be set.
