Abstract

The invention relates to the technical field of lost foam molds and particularly discloses a loader transmission case lost foam mold with a multi-stair inclined cross runner, which comprises a sprue gate and is characterized in that a vertical runner is fixed to the small gate side of the sprue gate and is of cylindrical structure, a skew runner is fixed to one end, close to the sprue gate, of thevertical runner, the cross runner is fixed to the middle of the vertical runner, an inclined runner is fixed to the end, far away from the sprue gate, of the vertical runner, a connection block in duckbilled palmate structure is fixed to the bottom of each of the skew runner, the cross runner and the inclined runner; a transmission case mold is fixed to the bottom ends of the connection blocks. Amain runner and a stair runner provided herein help improve thermal balance of the mold herein and help provide feeding and transmit static pressure upon cooling and coagulating; the duckbilled connection blocks help decrease the runner removal difficulty and facilitate the separation of the runners and the transmission case finally.

Description

technical field [0001] The invention relates to the technical field of lost foam, in particular to a lost foam of a loader gearbox body with a multi-layer stepped inclined runner. Background technique [0002] Lost foam casting, also known as dry sand solid mold negative pressure casting, is called EPC abroad. It is one of the most advanced casting processes in the world at present. It is known as a "revolution" in the history of casting. It is called the 21st century at home and abroad. Green casting. [0003] The runner can improve the thermal balance of the mold, but it still can’t be completely improved for some complex castings. Therefore, we propose a multi-layer stepped runner-type loader gearbox body lost foam to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a multi-layer stepped inclined runner loader gearbox body lost mold. [0005] In order to achieve...
