Embodiment bis-
For clearly showing admission main line, go out the structure of vapour main line, in Fig. 2 and Fig. 3, omitted mould, only provided the moulding of the institute of machined on mould admission main line, go out vapour main line, admission branch road, go out the contour structure of vapour branch road and part distribution pipeline.As shown in Figures 2 and 3, for making as far as possible the quantity of steam by entered each distribution pipeline 1.1 by admission main line 1.2 equate, reduce to be provided with the final mould inside temperature contrast everywhere of distribution pipeline 1.1, admission main line 1.2, go out the setting of should staggering of the central axis of vapour main line 1.3 and the central axis of each distribution pipeline 1.1, it is admission main line 1.2, go out vapour main line 1.3 and can not face toward a certain distribution pipeline 1.1, because when admission main line 1.2, go out vapour main line 1.3 facing to a certain distribution pipeline 1.1, especially just to time, a large amount of steam can pass through rapidly from this distribution pipeline 1.1, thereby destroy the relative evenness of steam flow between distribution pipeline 1.1, in addition, make total distance that steam flows through in each distribution pipeline 1.1 also can be different, capital causes the mould inside difference of temperature everywhere, affect injecting products quality.
Based on technique scheme, preferably, for making distribution pipeline 1.1 can be distributed in the differing heights position in mould 1, and make distribution pipeline 1.1 can there is the different flow directions, in the present embodiment, on admission main line 1.2, be communicated with along its length the admission branch road 1.2.1 of multiple different directions, correspondingly, what go out to be communicated with along its length on vapour main line 1.3 multiple different directions goes out vapour branch road 1.3.1, in many distribution pipelines 1.1 partly or entirely, its entrance point is communicated in admission branch road 1.2.1, and then be communicated in admission main line 1.2, correspondingly, the port of export of described distribution pipeline 1.1 is communicated in out vapour branch road 1.3.1 and then is communicated in out the correspondence position on vapour main line 1.3.
Due to admission branch road 1.2.1, go out vapour branch road 1.3.1 respectively at admission main line 1.2, go out diverse location and direction difference on vapour main line 1.3, thereby can make distribution pipeline 1.1 be distributed in the differing heights position in mould 1, also can make distribution pipeline 1.1 there is the different flow directions, make the each point place, inside of mould 1 can obtain homogeneous heating simultaneously.For large mold, by admission branch road 1.2.1 is set, go out length and the direction of vapour branch road 1.3.1, the distribution pipeline 1.1 that also can distribute equably in mould 1, realizes in mould homogeneous heating everywhere, can meet the needs of large mold homogeneous heating.
Embodiment tri-
In the present embodiment, admission main line 1.2, the internal diameter that goes out vapour main line 1.3 equate, the internal diameter of each distribution pipeline 1.1 also equates, and be the 1-1.2 times of many distribution pipelines 1.1 internal diameter sums.If admission main line 1.2, the internal diameter that goes out vapour main line 1.3 are less than many distribution pipelines 1.1 internal diameter sums, can be in steam supply process, inevitably there is the phenomenon of local steam supply deficiency, thereby will cause having the quantity of steam of one or several distribution pipeline 1.1 to be less than other distribution pipeline 1.1, temperature is inconsistent everywhere to cause mould, therefore, admission main line 1.2, the internal diameter that goes out vapour main line 1.3 should equal or be slightly larger than many distribution pipelines 1.1 internal diameter sums, are advisable with above-mentioned multiple.
When high-temperature steam starts mould to heat after each distribution pipeline 1.1 enters into mould, along with constantly entering of follow-up steam, the steam of front end is pushed out distribution pipeline 1.1.In this process, the logical heat transfer of steam is heated to mould, and the temperature of himself reduces rapidly, under the certain prerequisite of each piping flow, the amplitude that vapor (steam) temperature reduces is to be directly proportional in the time of distribution pipeline 1.1 interior stops to steam, same steam source of the gas, and distribution pipeline 1.1 is longer, steam residence time is longer, and it is just larger that temperature reduces amplitude.Therefore, the length of each distribution pipeline 1.1 should be consistent, thereby ensure the uniformity of heating.
In like manner, the shape of each distribution pipeline 1.1 also should be tried one's best unanimously, is preferably straight-through pipeline, makes the length of each distribution pipeline 1.1 consistent, ensures the uniformity of heating.
In the time having non-straight-through pipeline not wait such as each distribution pipeline 1.1 length of bending pipeline in many distribution pipelines 1.1, the distribution pipeline 1.1 that length is grown is arranged on the air intake 1.2.2 place near admission main line 1.2, so that it is filled more fully, alleviate the inhomogeneous situation of heating.

Embodiment tetra-
Preferably, due to for large mold, reach the desired Fast Heating of high light Shooting Technique and cooling fast, the diameter of distribution pipeline 1.1 should be larger, to increase flow and the flow velocity of high-temperature steam or cooling water, but because steam pipework is machined moulding on mould 1, distribution pipeline 1.1 diameters are larger, more easily cause on mould 1 because effect of stress produces cracking, in the present embodiment, the diameter of distribution pipeline 1.1 is advisable with 4-13mm, can ensure the high light Shooting Technique of large mold Fast Heating and cooling requirement fast, on mould 1, do not produce larger stress more again simultaneously.
In like manner, vertical range between the die joint of distribution pipeline 1.1 and mould 1 is less, be that distribution pipeline 1.1 is nearer apart from the die joint of mould 1, Steam Heating efficiency is higher, more easily causes man-hour mould 1 to ftracture, because the vertical range between distribution pipeline 1.1 and the die joint of mould 1 is generally 1-25mm and add apart from nearlyer distribution pipeline 1.1, determine according to injecting products size, injecting products size is larger, and mould 1 volume is larger, the corresponding increase of this distance.
Be to improve Steam Heating efficiency and prevent that mould 1 from ftractureing under effect of stress in order to take into account equally, at the distribution pipeline 1.1 being arranged on same level height, the spacing of adjacent distribution pipeline 1.1 is advisable with 6 ~ 50mm.
In addition, the edge of the die cavity of mould 1 adopts round-corner transition, also can effectively reduce stress concentrates, improve die life, and for large mold, because admission main line 1.2, the length that goes out vapour main line 1.3 and internal diameter can corresponding increases, for avoiding processing admission main line 1.2 on mould, while going out vapour main line 1.3, air intake 1.2.2, venthole 1.3.2 place cracking, also should suitably mold thickness be strengthened simultaneously, mould strength is compensated, reduce Drilling operation stress, avoid cracking.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
