Abstract
The utility model discloses a double-layer filtering pouring device, which comprises a pouring cup, an upper cross runner extending from the lower end of the pouring cup to two sides, a straight runner extending downwards from two ends of the upper cross runner, and a lower cross runner arranged below the straight runner and communicated with the two straight runners simultaneously; an upper filter is arranged inside the joint of the sprue and the upper cross runner, and a lower filter is arranged inside the joint of the sprue and the lower cross runner. The filter with the upper layer and the lower layer is used for enhancing the slag stopping capacity and purifying the molten metal, and meanwhile, the designed position of the filter is placed under the sprue with large fall, so that the scouring effect of the molten metal on the casting mold is greatly weakened.
Description
Technical Field
The utility model belongs to water jacket psammitolite makes the field, relates to a double-deck pouring device that filters.
Background
At present, many casting enterprises make oversize improvement attempts aiming at a gating system, and the purpose of the improvement attempts is mainly to optimize the pouring time, control the flow rate to prevent turbulent air entrainment and sand washing, enhance the skimming function of the gating system and the like, but the methods are different and are not improved enough.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to above shortcoming, the utility model provides a double-deck pouring device that filters.
The technical scheme is as follows: in order to solve the above problem, the utility model discloses can adopt following technical scheme:
a double-layer filtering pouring device comprises a pouring cup, an upper cross runner extending from the lower end of the pouring cup to two sides, straight runners extending downwards from two ends of the upper cross runner respectively, and a lower cross runner which is arranged below the straight runners and is communicated with the two straight runners simultaneously; a plurality of inner gates respectively extend from two sides of the lower horizontal pouring gate; an upper filter is arranged inside the joint of the sprue and the upper cross runner, and a lower filter is arranged inside the joint of the sprue and the lower cross runner.
Furthermore, a straight pouring pit is arranged at the joint of the lower cross gate and the straight gate, and the width of the straight pouring pit is larger than that of the lower cross gate.
Has the advantages that: compared with the prior art, the utility model discloses double-deck filtration pouring device is equipped with upper and lower two-layer filter, can strengthen pushing off the slag ability and purify the molten metal, places its design position under the very big sprue of drop simultaneously, and it has weakened the scouring action of molten metal to the casting mould greatly.
Drawings
FIG. 1 is a perspective view of a two-layer filtration casting apparatus.
FIG. 2 is a schematic view of a double-layer filtration casting apparatus during casting.
Detailed Description
With reference to fig. 1 and 2, the utility model provides a pair of double-deck pouring device that filters, including pouring basin 1, from pouring basin 1 lower extreme to the last runner 2 of both sides extension, from the sprue 4 of 2 both ends difference downwardly extending of last runner, install in sprue 4 below and simultaneously with the lower runner 5 of two sprue intercommunications. And a plurality of inner gates 8 respectively extend from two sides of the lower horizontal pouring gate. The pouring cup 1 is used for bearing the metal liquid flow from a pouring ladle and leading the metal liquid flow into a pouring system, so that splashing and overflow are prevented, direct impact of the metal liquid on a casting mold is reduced, a certain slag stopping function is realized, and the static pressure of the metal liquid is improved. The upper runner 2 is used to distribute the flow and store the cryogenic molten metal, initially containing gas and dross.
An upper filter 3 is arranged in the joint of the sprue 4 and the upper runner 2 and used for blocking slag and purifying molten metal. The lower filter 6 is arranged in the joint of the sprue 4 and the lower cross runner 5 and used for secondary slag blocking and metal liquid purification, and meanwhile, the filter is ingeniously placed under the sprue 2 with large drop, so that the scouring effect of the metal liquid on the casting mold is greatly weakened. A straight pouring pit 7 is arranged at the joint of the lower cross pouring gate 5 and the straight pouring gate 4, and the width of the straight pouring pit 7 is larger than that of the lower cross pouring gate 5. The straight pouring channel nest 7 has the functions of relieving the scouring effect of molten metal, shortening the highly turbulent region at the corner of the straight cross pouring channel and reducing the local resistance coefficient and head loss at the corner.
The present invention embodies a number of methods and approaches to this solution, and the above description is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be construed as the protection scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
