Servo-driven multi-station vacuum forming machine for refrigerator door liners

Abstract

The invention belongs to the technical field of refrigerator door liner forming machines, and in particular, discloses a servo-driven multi-station vacuum forming machine for refrigerator door liners.The vacuum forming machine comprises a lower die base; the upper surface of the lower die base is provided with a die cavity; ventilation holes are formed in a body of the lower die base; the bottompart of the lower die base is connected with vacuum suction pipes; the vacuum suction pipes are connected with the ventilation holes correspondingly; bottom ends of the vacuum suction pipes are connected with an inlet of a vacuum suction pump; the left side and the right side of the upper surface of the lower die base are each longitudinally provided with an upright column; the upright columns aresleeved and connected with an upper transverse plate; and the lower surface of the upper transverse plate is provided with a mounting groove. Under the action of the cooperation of a driven gear, a servo-driven motor and a drive gear, the upper transverse plate can move up and move down by servo control, and thereby, the upper transverse plate gets close to and is separated from the lower die base; under the action of the cooperation of an adjusting screw rod and an adjusting screw hole, after position adjustment, the adjusting screw rod has a locking effect, and thereby, the situation of falling cannot occur after adjustment.

Description

technical field [0001] The invention relates to the technical field of refrigerator door inner tube forming machines, in particular to a servo-driven multi-station refrigerator door inner tube vacuum forming machine. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. [0003] The volume of household refrigerators is usually 20-500 liters. In 1910, the world's first compression refrigeration household refrigerator came out in the United States. In 1925, the Swedish Lido Company developed a household absorption refrigerator. In 1927, General Electric Company of the United States developed a fully enclosed refrigerator. In 1930, the air-cooled continuous diffusion absorption refrigerat...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a servo-driven multi-station refrigerator door liner vacuum forming machine to solve the problem that the existing vacuum forming machine proposed in the above background technology is inconvenient to operate and has too many controls on the mold of the forming machine. It is manually opened and closed, which is not convenient enough and has low efficiency
