A translational automatic mold change mechanism

Abstract

The invention provides a translational automatic mold change mechanism, which relates to the technical field of box foaming equipment mold change, including a support frame, a translation transmission mechanism and a vertical transmission mechanism. The support frame includes a left frame and a right frame, and the left frame The inside of the frame is equipped with foaming equipment, and the inside of the right frame is equipped with a mold changing trolley through a translational transmission mechanism. The side of the right frame far away from the left frame is provided with a mold storehouse. Equipped with the same mold transfer mechanism as on the foaming equipment. In the present invention, through the setting of the translation transmission mechanism and the vertical transmission mechanism, the movement of the mold in the horizontal direction and the vertical direction during the replacement process is realized, and the setting of the servo motor makes the entire transmission process accurate, and the whole invention changes the original The method of flipping and changing the mold, the position of the mold changing is accurate, the speed of the mold changing is fast, and there is no need to stop the production line when changing the mold, which improves the production efficiency, is safe and effective, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of mold change for box foaming equipment, in particular to a translational automatic mold change mechanism. Background technique [0002] In the production line of refrigerators, box foaming equipment is a necessary component. When the refrigerator box is foamed, a mold is required. The mold for foam molding is a plastic foam mold. The foamable resin is directly filled into the mold, and it is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large amount of The tiny nuclei grow, and the nuclei grow to make foam plastic parts. Before foaming, the mold needs to be installed on the box foaming equipment, but when producing refrigerator liners of different sizes, because the distance between the refrigerator liner and the mold changes, the original mold must be replaced. There is a certain gap between the refrigerator liner and the mold, so that the foaming can be carried out no...

Problems solved by technology

[0004] However, due to the heavy weight of the entire replacement mold, if the overturning and conversion mold is completed through the cooperation of the overturning frame, the overturning power mechanism and the overturning locking mechanism, in the process of overturning, first, the entire overturning frame plus the mold is simply passed It is difficult to turn over the whole assembly by turning over the motor and the gear plate. Second, even if the entire turning frame is driven and turned by the turning motor, there is a lot of inertia in the turning, and it is difficult to stop at the highest point in time; second, the When the device is changing molds, it needs to stop production on the whole line, which affects the production process. At the same time, changing molds requires high precision. The tightness of the above-mentioned devices is not high, and it is difficult to ensure the accuracy of mold changing
