Die changing trolley capable of achieving automatic centering based on gravity action and using method thereof

Abstract

The invention discloses a die changing trolley capable of achieving automatic centering based on gravity action and using method thereof. The die changing trolley comprises a movable trolley body, a die changing platform and a push-pull mechanism, the push-pull mechanism is arranged on the die changing platform, and two supporting plates are fixedly connected to the left side and the right side of the upper surface of the movable trolley body; and the die changing platform is slidably connected between the two supporting plates through a sliding assembly, the left side and the right side of the lower surface of the die changing platform are movably connected with the supporting plates through lifting assemblies, and centering assemblies are arranged at the left side and the right side of the upper surface of the die changing platform. A spur gear can relatively move relative to a rack under the gravity action of a die, a screw rod can be driven to rotate through cooperation of the spur gear and the rack, the screw rod can drive a push plate to move in the rotating process, the die is clamped and fixed through a rubber pad in the moving process of the push plate, and therefore the die can be limited, the die is prevented from moving left and right, and the die is automatically centered before being installed.

Description

technical field [0001] The invention relates to the technical field of a mold changing trolley, in particular to a mold changing trolley for automatic centering based on gravity and a method for using the same. Background technique [0002] Molds are molds or tools used for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain various required products. They are the core of modern manufacturing and are widely used because they involve all aspects of production and manufacturing. In a modern factory. Due to the requirement of stability, the mold has the characteristics of large volume and heavy weight, so the position of the mold is difficult to move easily. However, the current mechanical processing plants generally do not only process one or several products, but manufacture or provide molds for processing and production according to customer needs. Since very few customers' orders require machining plan...

AI Technical Summary

Problems solved by technology

[0003] In order to adapt to molds of different widths, the existing mold changing trolleys usually have a relatively large width. Fast or uneven ground, etc., may cause the position of the mold to deviate. In the subsequent mold loading, it is necessary to manually adjust the position of the mold, and the operation is cumbersome and laborious.
