Description

Slag stopping pouring cup for sand-coated iron mold for grouting sleeve

Technical Field

The utility model relates to a grout sleeve's equipment for casting for the high-speed railway, concretely relates to grout sleeve covers sediment runner of sand with swage belongs to grout sleeve casting technical field for the high-speed railway.

Background

In the metal part casting process, the pouring cup is often needed to be used as a drainage tool of molten metal for the sand mold die, and molten iron can be effectively prevented from splashing during pouring. The sprue cup mainly has two shapes, one is funnel-shaped, the structure is simple, but gas and slag are easy to be involved; the other is basin type, the pouring effect is relatively good, and slag and air bubbles are separated favorably. The grouting sleeve is also called as a grouting sleeve joint or a sleeve grouting joint, when connecting reinforcing steel bars, rapid-hardening non-shrinkage grouting materials are injected, the reinforcing steel bars and the sleeve are connected by virtue of the bonding and meshing action between materials, in order to obtain the grouting sleeve with compact tissue and no shrinkage cavity, a part of enterprises adopt an inclined pouring process to finish pouring, and specifically, a section mould is inclined (the included angle between the section mould and the horizontal direction is 6-8 degrees) during pouring. Therefore, when the prior art pot-type pouring cup with the flat bottom and the flat top is applied to inclined pouring, under the condition that the requirement of the liquid level depth of the pouring cup is met, the part of the pouring cup positioned at the inclined high end side is greatly higher than the liquid level of the pouring cup, so that the action of the part is ineffective.

Disclosure of Invention

To the not enough of above-mentioned prior art existence, the utility model aims at providing a structural design is more reasonable and be applicable to the pushing off the slag runner of slope pouring grout sleeve foundry goods.

In order to achieve the above object, the utility model adopts the following technical scheme: a slag stopping pouring gate of sand-coated iron mold for grouting sleeve comprises a groove type pouring gate main body, and is characterized in that the groove type pouring gate main body is provided with an inclined bottom and a horizontal top during inclined pouring; a plurality of slag blocking plates are fixed in the groove type sprue main body along the length direction of the groove type sprue main body, and a gap is reserved between the bottom of each slag blocking plate and the adaptive position of the inner bottom of the sprue main body; the slag blocking plate close to the lower end of the inclined bottom of the groove type pouring gate main body and the corresponding groove type pouring gate main body form a pouring inlet area, and a first-stage slag blocking area is formed between every two adjacent slag blocking plates; the slag blocking plate close to the high end of the inclined bottom of the groove type pouring gate main body and the corresponding groove type pouring gate main body form a pouring outlet area, a funnel-shaped pouring outlet which penetrates through the bottom of the pouring gate main body and protrudes out of the inner surface and the outer surface of the bottom of the pouring gate main body is arranged at the inclined bottom of the pouring gate main body at the pouring outlet area, and a filter screen covers the inner end of the pouring outlet.

Compared with the prior art, the utility model discloses the beneficial effect who possesses is:

1. the sprue body is designed into a groove shape and is provided with the inclined bottom and the horizontal top, so that the requirement on the depth of the liquid level of the sprue can be met during inclined pouring, the volume of the sprue body is relatively reduced, and materials are effectively saved;

2. the design of the inclined bottom, particularly the design of the inclined inner bottom can play a good role in assisting in slag stopping, and the transition part which is partially arranged in the sprue main body in the prior art can be replaced;

3. the pouring outlet is designed into the inner surface and the outer surface of the bottom of the convex pouring gate main body, so that the outer surface of the bottom of the convex pouring gate main body of the pouring outlet can be conveniently inserted into the sprue of the section mould while the function of stopping slag is further achieved, and the positioning of the pouring cup and the section mould is realized.

the pouring gate comprises a pouring gate main body 1.1, an inclined bottom 1.2, a horizontal top 2, a slag blocking plate 3, a pouring inlet area 4, a slag blocking area 5, a pouring outlet area 6, a pouring outlet 7, a filter screen 8, a section die 9 and a tripod.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The following are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any equivalent or similar substitutes should fall within the scope of protection of the present application without departing from the inventive concept.
