Abstract
This utility model is related to a kind of low pressure casting combination type cast gate a set of cups, including sprue bush and grafting cup at an upper portion thereof, and the cup is plugged on the depth in the sprue bush not less than 15mm；The cast chamber run through in the cup and sprue bush, including being from top to bottom upper cavity volume section, middle cavity volume section and lower cavity volume section successively, the upper cavity volume section is the potting syrup runner in cup, the middle cavity volume section and lower cavity volume section are the potting syrup runner in sprue bush, and the middle cavity volume Duan Weiwu pattern drafts face section directly；This utility model solves the problems, such as casting withdrawing pattern.
Description
Technical field
This utility model is related to a kind of cup；More particularly to a kind of low pressure casting combination type cup.
Background technology
In low pressure casting process, molten metal is risen by stalk, from lower to upper in metal under certain pressure effect
Before liquid enters mold cavity, needs first pass through the cup being connected with mould ingate, steady by the molten metal of cup
Entrance and be full of mold cavity.On the one hand the effect of cup is drain and insulation, is on the other hand to avoid molten metal to casting
Type washes away.And traditional cup that low pressure casting is generally used is cylinder iron to be made, as cast iron radiating is very fast, insulation is imitated
Really poor, molten metal temperature after cast iron cup reduces very fast, so as to cause casting mold fill type and feeding capacity is poor.Afterwards
Carry out in industry and invented ceramic pouring cup and replace traditional cast iron cup.Although ceramic pouring cup is incubated than cast iron cup
Effect is good, but ceramic pouring cup is installed with the metal filter screen of cast gate when contacting, as direct labor installs inequality of exerting oneself, ceramics
Cast gate is easy for going to sticks and staves.For this fragile ceramic pouring cup, it is difficult in batch production.
In document CN104117661A, ceramic cast gate a set of cups, cup are placed on sprue bush, constitute cast gate a set of cups；Pour
Cup is cup-shaped, and cup chamber top is cast gate, and cup bottom is provided with lower inserted terminal；Sprue bush is round platform tubulose, and outer wall is only provided with
Rotating ring, top have cup interface, and liquid outlet is provided with tube chamber.
The above-mentioned ceramic cast gate a set of cups used in batch production process, it may appear that withdrawing pattern；And because molten metal is pierced
To the problem between cup and sprue bush, causing cast gate a set of cups service life short.
The content of the invention
The purpose of this utility model is to solve molten metal to be drilled between cup and sprue bush, causes cast gate a set of cups to make
With the problem of short life.
In order to solve the above problems, the utility model proposes the cup including sprue bush and grafting at an upper portion thereof, described
Cup is plugged on the depth in the sprue bush not less than 15mm；The cast chamber formed between the cup and sprue bush,
Including the upper cavity volume section, middle cavity volume section and lower cavity volume section that from top to bottom once connect, the upper cavity volume section is in cup
Potting syrup runner, the middle cavity volume section and lower cavity volume section are the potting syrup runner in sprue bush, and the middle cavity volume section is
Facing directly without pattern draft.
Further, drainage screen construction section is formed with the upper cavity volume section, the drainage screen construction section is without pattern draft
Face section directly.
Further, the drainage screen construction section is located at the hypomere of the upper cavity volume section.
Further, the hardness and wearability of the cup is more than the sprue bush.
Further, under the sprue bush, concave end has erecting bed terrace, and the erecting bed terrace is for the cast gate
Set carries out axial limiting.
The beneficial effects of the utility model are：
1st, Sealing Surface is formed between the sprue bush and cup of grafting cooperation, with the increase of cup inserting depth,
Sealing Surface gradually can increase, and when inserting depth exceedes cup depth is not less than 15mm, Sealing Surface just be enough to effectively prevent
Potting syrup is drilled in the gap between sprue bush and cup.
2nd, in actual low pressure casting, the epimere of middle cavity volume section occurs remaining potting syrup solidifying body, middle cavity volume herein
In section, facing directly without pattern draft can prevent down withdrawing pattern.
3rd, filter screen construction section can facilitate the installation of drainage screen to position, and the steady placement for drainage screen provides condition.
4th, in low pressure casting, lower cavity volume section is directly connected with holding furnace riser liquid, and under sprue bush, concave end has erecting bed
Terrace, sprue bush is fixed between lower mold mounting plate and lower mould.
Description of the drawings
With reference to the accompanying drawings and detailed description this utility model is described in further detail：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is mounting structure schematic diagram of the present utility model；
In figure：In the upper cavity volume section of 1- cups, 11-, 111- drainage screen construction sections, 2- sprue bush, 21- under cavity volume section, 22-
Mold mounting plate under mould, 4- under cavity volume section, 23- erecting bed terraces, 3-.
Specific embodiment
Referring to Fig. 1, this utility model low pressure casting combination cast gate a set of cups, including cup 1 and sprue bush 2.In sprue bush 2
Top be formed with the heavy platform hole installed for cup 1, cup 1 is by coordinating being plugged on sprue bush 2 with heavy platform hole.
The cup 1 for coordinating is contradicted with heavy platform hole, its inserting depth is not less than 15mm.
Through there is cast chamber in cup 1 and sprue bush 2, cast chamber includes the upper cavity volume section 11, cast gate in cup 1
Middle cavity volume section 21 and lower cavity volume section 22 in set 2.Upper cavity volume section 11 is overall in " eight " font with pattern draft, middle cavity volume
Section 21 is the section of facing directly without pattern draft, and lower cavity volume section 22 is overall in gradient just " eight " font.
Drainage screen is installed in upper cavity volume section 11 for convenience, drainage screen construction section is provided with the hypomere of upper cavity volume section 11
111, drainage screen construction section 111 faces section directly without pattern draft.Simultaneously as the installation site of drainage screen is in cup 1,
The hardness and wearability that cup 1 is required is more than sprue bush 2, can so reduce cup 1 because being subject to install drainage screen pressure
Damaged problem, so as to reduces cost to a certain extent, improves service life of the present utility model.
Referring to Fig. 1, Fig. 2, in order to this utility model is installed between lower mould 3 and lower mold mounting plate 4, in sprue bush 2
Lower end depression is formed with erecting bed terrace 23, and the briquetting coordinated with erecting bed terrace 23 is bolted to connection to be installed in lower mould
On plate 4.
