Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is provided, and is described in detail, makes to be better understood when
Function of the present utility model, feature.
As shown in Fig. 2 being to be adjusted to fill according to the baking oven mold temperature uniformity of a preferred embodiment of the present utility model
Put, if the device includes a fixed support 1 and a compressed air main pipeline 2 being fixed on the fixed support 1 and dry-pressing
Contracting air subtube 3, each compressed air subtube 3 include the pipeline main line 31 that one end is vertically connected with main pipeline 2 and
One or more pipeline branch roads 32 diverged by pipeline main line 31, the end of each pipeline branch road 32 is provided with one group of nozzle 4；Its
In, the pipeline main line 31 of compressed air subtube 3 is provided with the multiple and one-to-one magnetic valve 5 of each pipeline branch road 32, this
A little magnetic valves 5 are integrated into a Ge Fa islands, instead of the multigroup nozzle 4 of solenoid valve control in each branch pipeline；Each pipeline branch road 32
Provided with a pressure-reducing valve 6.
In another embodiment, as shown in figure 3, each compressed air subtube 3 is provided with one group of nozzle 4；Wherein, press
3 are provided with a magnetic valve 5 and a pressure-reducing valve on part compressed air subtube between contracting gas main duct 2 and nozzle 4
6, thus each compressed air subtube 3 can pass through magnetic valve 5 control one group of nozzle 4.For convenience of discussing, hereafter all in accordance with this
Embodiment is described in detail.
As shown in figure 3, nozzle 4 is arranged at the hot blast wind outlet area of the upper air duct 301 of last heating station of baking oven
At domain, i.e., the tuyere 3011 of the bottom of neighbouring upper air duct 301.Because mould is arc, lower air duct 302 is from mould farther out, warm
Degree will not be too high, so nozzle 4 need not be set adjacent to the tuyere 3021 of lower air duct 302.
As shown in figure 4, arranging multigroup nozzle 4 at the hot blast air-out region of the upper air duct 301, every group of nozzle 4 is located at
On same compressed air subtube 3, the quantity and position distribution of every group of nozzle 4 can carry out phase according to the structure and size of mould
The arrangement answered, to cover, top on mould is all to be likely to occur the too high region of temperature, can so adjust according to the actual requirements
The temperature in any region for being likely to occur high temperature of mould, it is ensured that the uniformity of mould bulk temperature.Preferably, every group of nozzle 4
Quantity is 3-5.In the present embodiment, according to the architectural feature of added mold heat, the nozzle of ten groups of temperature homogeneity adjustment is returned
Tuyere 3011 of the road adjacent to the bottom of upper air duct 301 is fixed.Because mould is that the chamber of a mould two is arranged symmetrically, therefore nozzle loop is also
It is symmetrically arranged, each five groups of left and right is No. 1 nozzle loop 401, No. 2 nozzle loops 402, No. 3 nozzle loops 403,4 respectively
Number nozzle loop 404 and No. 5 nozzle loops 405.Wherein No. 1 nozzle loop 401, No. 2 nozzle loops 402 and No. 5 nozzle loops
405 every groups include 3 nozzles；No. 4 nozzle loops 404 and No. 3 loops of nozzle 403 include 5 nozzles.
The structure of nozzle 4 is as shown in Figure 5.Nozzle 4 include the nozzle 4 include nozzle base 41, it is hollow and with spray orifice
421 nozzle body 42 and the locking nut 43 for being socketed on nozzle body 42 and being threadedly coupled with nozzle base 41.Locked when unclamping
After nut 43, nozzle body 42 can turn to any required angle, in place after, locking nut 43 is locked, by nozzle body 42
It is fixed on desired position.It is possible thereby to realize the regulation of the angle of nozzle body 42, the spray orifice 421 of nozzle body 42 is controlled to go out
Wind angle, realizes the multiple control programs adjusted to mold temperature uniformity.Nozzle 4 is fixed on subtube 3 by fixing nut 7

Referring again to Fig. 3, in the present embodiment, the operation principle of baking oven mold temperature uniformity adjusting apparatus is as follows.Come
Enter main pipeline, compressed air main pipeline 2, each compressed air subtube 3 and one group pair from factory building compressed air gases at high pressure
Nozzle 4, magnetic valve 5 and the pressure-reducing valve 6 answered constitute a loop.Each loop is equipped with magnetic valve 5 and pressure-reducing valve 6, uses
Thermal imaging system detects the temperature of mould different zones, and the artificial keying according to temperature data control magnetic valve.For mould temperature
Degree is higher than the region of range of set value, and magnetic valve 5 opens the nozzle loop of this overlying regions, nozzle blowout pressure-air, drop
The temperature of low lower zone mould, when temperature does not need work less than setting value, magnetic valve cut-out；By adjusting decompression
The aperture of valve 6, the size of the air pressure of control compressed air subtube 3, so that control nozzle 4 goes out wind pressure, passes through decompression
Valve can control the gas pressure in each loop, and thereby may be ensured that mould diverse location temperature is different needs to high-pressure gas flow
Otherwise same requirement, regulation mold temperature is dropped in the range of set-point temperature.Pass through the locking nut 42 and nozzle body to nozzle 4
43 regulation, controls the air outlet angle of nozzle, so as to accurately control the position of mould wind-engaging.The baking oven mold temperature uniformity is adjusted
Engagement positions by regulation whether air-out, go out wind pressure and air outlet angle and realize the multiple controlling parties adjusted to mold temperature uniformity
Case.
Above-described, preferred embodiment only of the present utility model is not limited to scope of the present utility model, this
Above-described embodiment of utility model can also make a variety of changes.I.e. every claims according to the present utility model application and
