Embodiment Construction

[0011] Such as figure 1 , 2 , Shown in 3, the present invention is connected with trapezoidal shovel head 2 at the lower end of handle 1, is respectively provided with curved milling cutter 3 on the both sides of shovel head 2, and rotation handle 4 is located at the upper end of handle 1. Through the above settings, the trapezoidal shovel 2 of the present invention is inserted into the casting sand mold 5, and the trapezoidal shovel 2 is driven to rotate by rotating the handle 4, and the curved milling cutters 3 on both sides of the trapezoidal shovel 2 connect the gate cup 6 with the direct pouring The floating sand on the inner wall of the channel 7 is cleaned, so that the interior of the sprue cup 6 and the sprue 7 is smoothly transitioned, and when the molten metal is poured into the sprue cup 6, the molten metal can enter the mold through the sprue 7 smoothly, avoiding Turbulent flow and flushing of the mold, no gas is involved during pouring, and the yield of castings...

Abstract

The invention discloses a Milling device for a foundry sand mould pouring gate, which is characterized in that a ladder-shaped shovel head is connected with the lower end of a handle, bent milling cutters are respectively arranged on two side edges of the shovel head, and a rotary handle is arranged at the upper end of the handle. Through the arrangement, the milling device can clear up the connection part of a foundry sand mould pouring cup and a sprue quickly in a labor-saving manner, so that the pouring cup and the interior of the sprue are in smooth transition with each other, molten metal enters into a casting mold stably, the turbulence and the washing to the casting mold are avoided, no gas is involved in pouring, and the casting finished product rate is increased.

Description

technical field [0001] The invention relates to a trimming tool for a casting sand casting system, in particular to a milling device for cleaning a casting sand runner. Background technique [0002] In casting production, the connection between the sprue cup and the sprue of the casting sand mold is not smoothly transitioned, and the molten metal cannot enter the mold smoothly, resulting in turbulent flow and flushing of the mold, and it is easy to get involved in gas during pouring, resulting in castings Defects such as pores, slag holes, etc., molten iron is easy to overflow, which poses a safety hazard to pourers. Contents of the invention [0003] The object of the present invention is to provide a milling device for cleaning casting sand runners. [0004] In order to achieve the above object, the present invention is connected with a trapezoidal shovel head at the lower end of the handle, curved milling cutters are respectively arranged on both sides of the shovel he...
