Translation type automatic mold replacement mechanism

Abstract

The invention provides a translation type automatic mold replacement mechanism, and relates to the technical field of box foaming equipment mold replacement. The translation type automatic mold replacement mechanism comprises a supporting frame, a translation transmission mechanism and a vertical transmission mechanism; the supporting frame comprises a left side frame and a right side frame; the interior of the left side frame is provided with foaming equipment, and the interior of the right side fame is movably provided with a mold replacement trolley through the translation transmission mechanism; a mold storeroom is arranged on the side, away from the left side frame, of the right side frame; and the top end of the inner side of a mold trough and the top of the mold storeroom are both provided with mold conveying mechanisms which are the same with a mold conveying mechanism on the foaming equipment. According to the translation type automatic mold replacement mechanism, by arrangingthe translation transmission mechanism and the vertical transmission mechanism, moving of a mold in the horizontal and vertical directions during replacing is achieved; by arranging a servo motor, the whole conveying process is accurate; and through the invention, an original turnover mold replacement mode is changed, the mold replacement position is precise, the mold replacement speed is high, aproduction line does not need to be stopped during mold replacement, the production efficiency is improved, safety and effectiveness are achieved, and the practicability is high.

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
