Detailed Description

In order to clearly understand the technical contents of the present invention, the following embodiments are specifically illustrated in detail.

As shown in fig. 1-5, for the embodiment of the automatic evacuation system for mold temperature controller of the present invention, the flow diagram shown in fig. 1-2 is used as an example to illustrate the automatic evacuation system of the present invention.

As shown in the flow block diagram of the mold temperature controller of fig. 1-2, the mold temperature controller relates to a media pump 1, a heating box 5, a float cylinder 6, a first pipeline 2 and a second pipeline 3, wherein the first pipeline 2 is arranged between the inlet of the media pump 1 and a mold, the second pipeline 3 is arranged between the outlet of the media pump and the mold, the heating box 5 is further arranged on the second pipeline 3, when the mold temperature controller works normally, media flow to the first pipeline 2 through the media pump 1, then enter the mold through the inlet of the mold, and flow out through the outlet of the mold, enter the second pipeline 3, and the media in the second pipeline 3 first enters the heating box 5 after heat exchange. During the circulation, substantially no medium is discharged from the discharge conduit 4. The opening of the solenoid valve 9 in the discharge line 4 is often 2 cases: the valve is opened when the machine is started and is used for discharging gas in each pipeline; when the medium pressure is too high, the valve is opened for pressure relief and discharge of a gas-liquid mixture.

The utility model provides an automatic emptying system is including setting up check valve 8 on second pipeline 3, and check valve 8 is through branch mouth of pipe 7 and 3 intercommunications of second pipeline, wherein, branch mouth of pipe 7 set up in second pipeline 3 with the junction of discharge pipeline 4 and the export of mould between. The setting of the one-way valve 8 does not affect the normal working state of the mold temperature controller, as shown in fig. 2, when the mold temperature controller is stopped and needs to be emptied, the media pump 1 is controlled to rotate reversely, air enters the second pipeline 3 through the one-way valve 8, and therefore media in the second pipeline 3, the mold and the first pipeline 2 are discharged to the discharge pipeline 4 in the media flowing direction opposite to the normal working state.

As shown in fig. 3-5, for the utility model provides an embodiment of check valve 8, wherein, check valve 8 include valve body 10 and set up in the inside case 13 of valve body, valve body 10 set up first valve port 11, case 13 set up second valve port 12, first valve port 11 with branch mouth 7 be linked together the mould temperature machine during normal work, first valve port 11 with second valve port 12 do not communicate after media pump 1 reverses, first valve port 11 with second valve port 12 be linked together for the air by second valve port 12 get into first valve port 11, reentry branch mouth 7 and second pipeline 3.

As shown in fig. 4 to 5, the valve core includes a valve ball 15 and a channel 18 disposed between the second valve port 12 and the valve ball 15, an upper end of the channel 18 is connected to the second valve port 12, a lower end of the channel 18 is connected to the valve ball 15, a diameter of the valve ball 15 is set to exceed an inner diameter of the channel 18, an elastic member 14 is disposed below the valve ball 15, and the valve ball can reach the state of fig. 5 by an elastic force of a spring when a medium is not supplied. A first sealing element 16 is arranged between the valve ball 15 and the lower end of the channel 18, and a second sealing element 17 is arranged between the outer surface of the valve core and the inner cavity of the valve body.

When the mold temperature machine is in a normal working state, the media pump rotates forwards, as the first valve port 11 is directly communicated with the second pipeline 3 through the branch pipe port 7, the first valve port 11 is filled with media, the pressure of the media is higher than the external atmospheric pressure, and the pressure of the media and the elasticity of the spring jointly push the valve ball to contact the sealing element upwards to achieve the sealing effect; when the media pump rotates reversely, the first valve port 11 is under negative pressure, i.e. lower than the atmospheric pressure, the steel ball is driven by the self weight of the steel ball plus the pressure difference to move downward, the outside air at the second valve port 12 reaches the first valve port 11 through the second valve port 12, and the media in the second pipeline 3, the mold and the first pipeline 2 are discharged to the discharge pipeline 4 in the media flowing direction opposite to the normal working state under the reverse rotation of the media pump.

Therefore, specifically use the utility model discloses an during automatic emptying system, can delay several seconds after the mould temperature machine is shut down, the pump reversal, during the reversal drainage, solenoid valve 9 is opened, because the pump reversal produces the negative pressure, the check valve is from external air of inhaling, under the effect of pump, the media in customer's mould, the pipeline is discharged the cooling water outlet by the pump, realizes the media evacuation function.

Adopted the utility model discloses an automatic evacuation system for mould temperature machine sets up the check valve, when needs evacuation, control media pump reversal can, after the media pump reversal, the air gets into the pipeline through the check valve, and the automatic media of hurling away in the pipeline need not to operate in addition.
