Abstract

The utility model discloses a forming mold of a water gap. The forming mold comprises a mold body, wherein the mold body consists of a base, a sleeve and a mold core column, wherein the lower end of the sleeve is sheathed on the base; and the mold core column is also inserted on the base. The forming mold is characterized by also comprising a hopper; the hopper is arranged at the upper end of the sleeve; a positioning column extends downwards from the central position of the hopper, and can be properly inserted into a hole at the upper end of the mold core column. The forming mold disclosed by the utility model has the advantages that since the hopper is additionally arranged at the upper end of the sleeve, not only can the problem of eccentricity of the mold core column be effectively solved, but also the purpose of high sand filling speed can be realized, the working efficiency is high and the economic benefit is higher.

Description

A kind of mould of the mouth of a river

Technical field

The utility model relates to a kind of mould of the refractory piece of casting, specifically a kind of mould of the mouth of a river.

Background technology

The casting water nozzle of existing foundry refractory is a kind of disposable refractory part, and use amount is big.Certainly, the mouth of a river commonly used simple in structure, agent structure is a column, and is provided with a through hole in the centre of column.Mouth of a river parts generally are to use refractory material through annotating sand, sinter molding, in the process of annotating sand and sintering, will use a kind of mould that will use to carry out, so the quality that mould designs can directly have influence on the production efficiency and the performance of products at the mouth of a river.Existing production mould is generally by being made up of base, sleeve, core post and funnel; The sleeve lower end is nested with on base; The core post also is inserted on the base; So core post upper end is a free arm,, the properties of product at the mouth of a river have directly been influenced in the eccentric problem that is easy to generate of the process of building molding sand.

The utility model content

The purpose of the utility model is to provide a kind of mould of the mouth of a river, can solve existing eccentricity issues of producing medium-sized stem stem, can realize the purpose of assembling fast simultaneously, increases work efficiency.

The technical scheme that its technical problem of the utility model solution is taked is: a kind of mould of the mouth of a river, comprise die ontology, and said die ontology is made up of base, sleeve and core post; Said sleeve lower end is nested with on base, and said core post also is inserted on the base, it is characterized in that; Also comprise a funnel; Said funnel is placed on the upper end of sleeve, in the centre of said funnel to extending below certain position post, said reference column just can the hole of insert type stem stem upper end in.

The beneficial effect of the utility model is: the utility model increases a funnel through the upper end at sleeve, both can effectively solve the eccentricity issues of core post, can realize annotating fast the purpose of sand again, and high efficiency has high economic benefit.

Fig. 5 is the full sectional view at the mouth of a river of the utility model production;

Among the figure: 1 base, 2 sleeves, 3 core posts, 4 molding spaces, 5 funnels, 6 reference columns, 7 mouths of a river, 8 dowels.

The specific embodiment

Like Fig. 1～shown in Figure 4, a kind of mould of the mouth of a river comprises die ontology; Die ontology is made up of base 1, sleeve 2 and core post 3, and sleeve 2 is tubulars of being processed by refractory material, and the profile at the mouth of a river 7 (as shown in Figure 5) that its shape and quilt are produced is consistent; Base 1 is discoid, is the mounting platform of sleeve and core post, and sleeve 2 lower ends are nested with on base 1; Core post 3 lower ends also are inserted on the base 1, and the inner space forms the molding space 4 at the mouth of a river.

Also comprise a funnel 5; Funnel 5 is placed on the upper end of sleeve; Centre at funnel is welded a reference column 6 downwards, and reference column 6 is below funnel, and reference column 6 is welded in the leak of funnel through dowel 8; Reference column 6 just can the insert type stem stem in the hole of upper end, forms a support in the upper end of core post 3 like this.

In annotating the process of sand, the sand material falls into the internal cavities of mould through funnel, and in this course, can not squint in the upper end of core post, can prepare mouth of a river parts efficiently.

In the utility model, the shape of molding space 4 can design according to the needs of reality, but should comprise the shape and the specification at the mouth of a river of casting usefulness commonly used at least, should not be limited to the figure that provides among the embodiment here.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims

1. the mould at a mouth of a river comprises die ontology, and said die ontology is made up of base, sleeve and core post; Said sleeve lower end is nested with on base, and said core post also is inserted on the base, it is characterized in that; Also comprise a funnel; Said funnel is placed on the upper end of sleeve, in the centre of said funnel to extending below certain position post, said reference column just can the hole of insert type stem stem upper end in.
