Abstract

The utility model discloses a kind of cast structure being improved riser feeding distance by core heating, comprise cast gate, cast gate is communicated with the die cavity of L-type rising head, the vertical section sidewall of L-type rising head is provided with riser neck, the horizontal segment of L-type rising head stretches in the core of hollow, core upper end is provided with foundry goods, and foundry goods left end contacts with riser neck.The utility model novel in structural design is reasonable, the horizontal segment of L-type rising head stretches in the core of hollow, foundry goods left end contacts with riser neck, makes the volume contraction stage of the Feeding channel of foundry goods when casting solidification remain liquid, thus makes rising head can effective feeding foundry goods.

Description

A kind of cast structure being improved riser feeding distance by core heating
technical field:
The utility model relates to casting manufacture field, particularly relates to a kind of cast structure being improved riser feeding distance by core heating.
background technology:
In order to obtain foundry goods that is complete, dense structure, in casting technique, first method: adopt the means increasing rising head, volume contraction when making molten metal condense into solid-state, the timely of molten metal that can obtain from rising head supplements.Easily produce in this casting technique and organize Feeding channel between unsound foundry goods thermojunction and riser neck and rising head often because Feeding channel solidifies in foundry goods thermojunction and rising head in advance, thus the molten iron in rising head can not be made to add in the foundry goods of volume contraction go, cause cast structure not fine and close.
In production practices, in order to compensate the not enough problem of above-mentioned riser feeding distance, usual casting process scheme is, increase chill at thermojunction position or foundry goods end, shape produces chill end region, thus increases the feeding distance of rising head.But due to iron chill shock chilling limited efficiency in this kind of method, or be subject to the restriction of riding position, be often difficult to reach necessary effect.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of cast structure being improved riser feeding distance by core heating, make the volume contraction stage of the Feeding channel of foundry goods when casting solidification remain liquid, thus make rising head can effective feeding foundry goods.
The technical solution of the utility model is as follows:
The cast structure of riser feeding distance is improved by core heating, comprise cast gate, it is characterized in that: described cast gate is communicated with the die cavity of L-type rising head, the vertical section sidewall of L-type rising head is provided with riser neck, the horizontal segment of L-type rising head stretches in the core of hollow, core upper end is provided with foundry goods, and foundry goods left end contacts with riser neck.
The described cast structure being improved riser feeding distance by core heating, be is characterized in that: the cross section of described riser neck is triangle.
The utility model has the advantages that:
The utility model novel in structural design is reasonable, the horizontal segment of L-type rising head stretches in the core of hollow, foundry goods left end contacts with riser neck, makes the volume contraction stage of the Feeding channel of foundry goods when casting solidification remain liquid, thus makes rising head can effective feeding foundry goods.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
See accompanying drawing:
The cast structure of riser feeding distance is improved by core heating, comprise cast gate 1, cast gate 1 is communicated with the die cavity of L-type rising head 2, the vertical section sidewall of L-type rising head 2 is provided with riser neck 3, the horizontal segment of L-type rising head 2 stretches in the core 4 of hollow, and core 4 upper end is provided with foundry goods 5, and foundry goods 5 left end contacts with riser neck 3, make the volume contraction stage of the Feeding channel of foundry goods 4 when casting solidification remain liquid, thus make L-type rising head 2 can effective feeding foundry goods.
The cross section of riser neck 3 is triangle.
First the utility model specifically prepares the core 4 of hollow with core box, utilize external mold to make foundry goods 5 and L-type rising head 2; Next utilizes the molten iron of melting gained to pour into from cast gate 1 finally to obtain cast article.
