Problems solved by technology

The single-channel pouring hopper is suitable for metal mold tooling with one mold and one cavity. When a metal mold tool has multiple cavities, in order to ensure the quality of the castings in each cavity, the filling process needs to meet the following conditions: the molten metal flows into each mold simultaneously. cavity, and the inflow speed is consistent. The ultimate goal is that the castings produced by the three cavities have no quality difference after various technical tests. The single-channel pouring hopper can no longer meet this technical condition.

Embodiment Construction

[0025] see figure 1 , the present invention provides a multi-channel pouring hopper, comprising a material holding chamber 1, the mouth of the material holding chamber 1 is provided with a diversion rib 2, and the flow diversion rib 2 divides the mouth of the material holding chamber 1 into a plurality of pouring streams Road 3. The material holding chamber 1 is used to temporarily keep warm and store the molten metal poured from the ladle, and at the same time keep the molten metal still to eliminate the turbulence of the molten metal flow; The channel is divided into multiple flow channels, and the structural optimization design is carried out by using numerical simulation, so as to realize the uniform distribution of the molten metal, which is the key structure.

[0026] see figure 2 , the shunt rib 2 that the present invention adopts is letter n type as a whole, wherein: H: the vertical height of the opening of the filling cavity; W: the horizontal width of the opening ...

Abstract

The invention belongs to the field of casting, and relates to a multi-channel pouring hopper, which includes a material holding cavity, and is characterized in that: the mouth of the material holding cavity is provided with a diversion rib, and the flow diversion rib divides the mouth of the material filling cavity equally For multiple pour runners. The invention provides a multi-channel pouring hopper which is easy to realize synchronous mold filling, has consistent casting quality and is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of casting, and relates to a tool for holding materials, in particular to a multi-channel pouring hopper. Background technique [0002] The pouring hopper is mainly used in the metal mold tilting casting process. Its function is to temporarily store the molten metal and eliminate the turbulent flow of the molten metal. During the tilting casting process, the molten metal flows into the cavity through the hopper flow channel. The existing hopper has a single-channel structure, and its working process is as follows: the ladle scoops out the metal liquid from the holding furnace and pours it into the hopper, and waits for a while to make the metal liquid stable. cavity to complete the filling process. The single-channel pouring hopper is suitable for metal mold tooling with one mold and one cavity. When a metal mold tool has multiple cavities, in order to ensure the quality of the castings in each cavity, the filling pr...
