Mold Fixing Device for Casting of Rail Transit Automatic Door

Abstract

The invention discloses a mold fixing device for rail transit automatic door casting, which includes a supporting mechanism, a casting mechanism and a fixing mechanism; the supporting mechanism includes a supporting seat, a main baffle is arranged on one side of the supporting seat, and A conveying table is provided; the casting mechanism includes a lower mold and an upper mold, the lower mold is arranged on one side of the main baffle plate, and is slidably connected with the support seat, and one side of the lower mold is provided with a pulling mechanism, and the One side of the upper mold is provided with a lifting mechanism; the fixed mechanism includes a rotating baffle, the bottom of the rotating baffle is provided with a rotating shaft, and a rotating mechanism is connected to the rotating shaft, and side baffles are provided on both sides of the lower mold The bottom of the side baffle is provided with a synchronous lifting device; the invention is safe and convenient to operate by taking out the casting, avoiding casualties caused by the fall of the upper mold when removing the mold, and can perform the mold removal operation in a relatively open space , easy to operate and high efficiency.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a mold fixing device for casting automatic doors of rail transit. Background technique [0002] The key steel castings for the load-carrying and driving of rail transit automatic doors (including door frames, brackets and other products) are important stress-bearing parts in the rail transit automatic door opening and closing system, and are key components of rail transit. The material that is easy to form is made into the structural shape of the part, and then put into the mold in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold, and then a fluid liquid is poured into the cavity, the liquid After cooling and solidification, parts with exactly the same shape and structure as the mold can be formed, but the installation of the mold is cumbersome, and the fixation is not firm enough to easily cause misalignment, and when disassembling,...
