Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, those skilled in the art is made to become apparent from
How ground understanding puts into practice the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
As shown in Figure 1, the utility model die heater adds heat transmission medium to be air, which includes heater group
Part, A end pipes road 10, B end pipes road 12, suction ventilator 14, high pressure air pump 15 and master controller 19.
Heater assembly comprising shell 1 and the ptc heater 2 being set in shell 1, the shell 1 are equipped with the ends A
Connector, B terminal adapters, temperature sensitive probe 4, compressed air channel 5 and leakage path 7, the bottom of shell 1 form a reflux and release
Area 3, the A terminal adapters are set to the top of shell 1, and the reflux that the B terminal adapters are set to 1 bottom of shell is released area 3,
The compressed air channel 5 is equipped with electromagnetism by accessing to the ptc heater 2 in shell 1, compressed air channel 5 outside shell 1
Valve 6 and pressure-regulating valve, the leakage path 7 are released area 3 by the reflux for accessing to 1 bottom of shell outside shell 1, leakage path 7
It is equipped with cooler 8 and silencer 9.Wherein, shell 1 is equipped with 4 interface of temperature sensitive probe of corresponding temperature sensitive probe 4, leakage path 7
It is equipped with the silencer interface of the cooler interface and corresponding silencer 9 of corresponding cooler 8.
The one end in A end pipes road 10, A end pipes road 10 connects A terminal adapters, and the other end connection in A end pipes road 10 is useful
The first distributor 11 of mold is accessed in the air of heating.B end pipes road 12, one end ends connection B connection in B end pipes road 12
The other end of device, B end pipes road 12 is connected with the second distributor 13 that the air for being heated in mold picks out.First distribution
Device 11 and the second distributor 13 are separately connected the both ends of mold.
Suction ventilator 14 is set on B end pipes road 12, the extraction of the air for being heated in mold.
High pressure air pump 15 comprising the cage modle fan blade 16 and motor 18 being connected by shaft coupling 17, the cage modle wind
Leaf 16 is set in the shell 1 of heater assembly and positioned at ptc heater 2 in the following, cage modle fan blade 16 is for ptc heater 2
