Description

Technical Field

[0001] The invention relates to the technical field of shaping material forming, in particular to a quantitative automatic opening door body foaming production line. Background Art

[0002] The foam layer of the refrigerator door plays a vital role in the refrigerator. First of all, the foam layer can prevent the heat exchange between the inside of the refrigerator and the external environment, thereby keeping the temperature inside the refrigerator constant. Specifically, the foam layer is wrapped between the outer shell and the inner tank of the box, effectively preventing the leakage of cold air in the box and maintaining a constant low temperature inside the box. In addition, the foam layer can also play a heat-insulating role and reduce the effect of heat and cold transfer. The foam layer can reduce the impact of the external temperature on the inside of the refrigerator and ensure the freshness and storage time of the food. This insulation effect has a significant improvement in the energy efficiency and preservation effect of the refrigerator.

[0044] Working principle: Start the electric slide rail 2 to drive the lower molds 3 to move, so that the abutting rods 31 move, so that the abutting rods 31 contact the inclined surface of the inclined block 73, so that the inclined block 73 moves toward the inside of the fixed seat 71, so that the two first spring expansion members 72 contract, so that the first wire 74 is released for a distance, so that the clamping rod 75 is no longer pulled, so that the two discharge pipes 77 are no longer clamped, and at the same time, due to the movement of the inclined block 73, the second wire 710 is released for a distance, and the two discharge pipes 77 are set to be made of rubber material, so that the output ends of the two discharge pipes 77 are in the two limit sleeves 78. The second clamping rod 75 is pressed against the second retaining member 714 and the second retaining member 72 is pressed against the second retaining member 716. The second clamping rod 75 is pressed against the second retaining member 717 and the second retaining member 72 is pressed against the second retaining member 718. , so that the clamping rod 75 moves toward the two fixed blocks 76, so that the two discharge pipes 77 are clamped by the two fixed blocks 76 and a clamping block, so that the discharge pipe 77 is closed, so that the raw material no longer flows out of the discharge pipe 77, and at the same time, due to the movement of the inclined block 73, the second wire 710 is pulled a distance, so that the connecting rod 79 is pulled, driving the two limit sleeves 78 to move, so that the output ends of the two discharge pipes 77 are pulled to the pipe openings facing upwards, preventing the residual raw material in the discharge pipe 77 from dripping onto the electric slide rail 2, and then the lower mold 3 moves away from below the discharge pipe 77, and the motor 46 is started to drive the connecting rod 79 to move. The connecting piece 45 rotates to rotate the upper mold 5 to a horizontal state, and then the electric telescopic rod 43 is started to drive the upper mold 5 to move downward, so that the upper mold 5 is fitted with the lower mold 3, and then the raw material is foamed to fill the mold. After the raw material is foamed and formed, the electric telescopic rod 43 is started to drive the arc block 44 to move upward, so that the connecting piece 45 moves upward, driving the upper mold 5 to move upward, and then the motor 46 is started to drive the connecting piece 45 to rotate, so that the upper mold 5 rotates, so that the foamed workpiece can be taken out, and then the lower mold 3 of the workpiece taken out continues to move and contact the blanking component 7 again to carry out the blanking and foaming of the raw material.
