Further, the included angle between the inclined ramp and the vertical channel is 135 degrees.
Furthermore, the tail end of the air supply air passage is provided with a conical air outlet, and the diameter of the conical air outlet is gradually reduced along the wind direction.
Furthermore, the lower edge of the inner diameter of the conical air outlet is flush with the bottom of the inner wall of the horizontal channel.
Further, the diameter of the vertical channel > the diameter of the inclined ramp > the diameter of the horizontal channel.
Further, the diameter of the horizontal channel is gradually reduced along the feeding direction.
The utility model has the advantages as follows:
1. the utility model discloses a disappearance mould feed structure has improved the feed structure of mould, separates foaming bead pan feeding mouth and air supply air flue, and after the foaming bead got into the horizontal channel in the mould, the wind footpath of air supply air flue directly blown to the foaming bead, and there is not the bending point in the wind direction, can not take place to block up, and the input speed accelerates greatly.

Detailed Description
In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
Example 1:
a feeding structure of a lost foam mold comprises a feeding channel communicated with a mold cavity 1, wherein the feeding channel comprises a vertical channel 2, an inclined ramp 3 and a horizontal channel 4, in the embodiment, an included angle between the inclined ramp 3 and the vertical channel 2 is 135 degrees, the starting end of the vertical channel 2 is connected with a bead conveying pipe, the tail end of the horizontal channel 4 is communicated with the mold cavity 1, and the inclined ramp 3 is smoothly connected between the vertical channel 2 and the horizontal channel 4. The expanded beads are conveyed through the bead conveyor tube into the vertical channel 2, through the inclined ramp 3 into the horizontal channel 4 and finally into the membrane chamber 1.
In order to avoid the foamed beads from being blocked in the passages, a supply air duct 5 is provided at a corner of the inclined ramp 3, and the supply air duct 5 is connected to a blower. The end of the air supply duct 5 is communicated with the inclined ramp 3 and faces the horizontal channel 4, and the air direction of the air supply duct 5 is consistent with the flow direction of the horizontal channel 4. The air supply duct 5 continuously supplies air into the horizontal passage 4. After the foaming beads enter the horizontal channel 4 in the mold, the air of the air supply air channel 5 is directly blown to the foaming beads, no bending point exists in the air direction, and blockage cannot occur, so that the foaming beads can be pushed to continuously enter the mold cavity 1 along the horizontal channel, and the feeding speed is greatly increased.
The tail end of the air supply air passage 5 is provided with the conical air outlet 6, the diameter of the conical air outlet 6 is gradually reduced along the wind direction, so that the air pressure of the air supply air passage 5 can be increased, the air outlet keeps larger blowing force, and the foaming beads are blown into the die cavity 1.
Follow the inner wall bottom parallel and level with horizontal passage 4 under the internal diameter of toper air outlet 6 to avoid appearing blowing and sweeping the blind area in toper air outlet 6 department, avoid the bead to pile up.
In this embodiment, the diameter of the vertical channel 2 > the diameter of the inclined ramp 3 > the diameter of the horizontal channel 4, the diameter of the vertical channel 2 is kept larger for the convenience of feeding, and the diameters of the inclined ramp 3 and the horizontal channel 4 are smaller for orderly entering the foaming beads into the mold cavity 1 under the blowing force of the conical air outlet 6, so as to prevent the beads from flowing back and stagnating along the inner wall of the horizontal channel 4.
In addition, the diameter of the horizontal channel 4 is gradually reduced along the feeding direction, so that on one hand, the large flash of the white mold is prevented, and on the other hand, the air pressure is increased, so that the foaming beads can rapidly enter the mold cavity 1 under the blowing force of the conical air outlet 6.
Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent replacement and modification or partial replacement that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
