Description

Pouring cup positioning seat for lost foam casting of cup opening coated film

Technical Field

The utility model relates to the technical field of lost foam casting equipment, in particular to a pouring cup positioning seat for lost foam casting of a cup opening coated film.

Background

FIG. 1 shows: the sprue cup 1 for lost foam casting is generally made of light refractory fiber materials integrally, is in a funnel shape with a large end and a small end, the large end and the small end are cylindrical, the diameter difference between the large end and the small end is large, the middle part of the sprue cup and the large end are connected in a seamless mode through a circular truncated cone, the sprue cup is hollow and communicated, and the wall thickness is 6-7 mm. An opening at the large end, namely a cup mouth, is used as a molten iron inlet during pouring, a layer of plastic film 2 needs to be wrapped, and single-sided adhesive tape paper 3 is wound to tightly wrap the film, so as to prevent molding sand from entering during molding; the small end is a molten iron outlet and is connected with the sprue.

The large end of the pouring cup 1 is upward and is in a large-upper-small state, so that the small end of the pouring cup 1 cannot be stable when being placed on a floor, and when a film is wrapped, an operator needs to grasp the plastic film 2 with one hand and wind the single-sided adhesive tape 3 with the other hand, and the pouring cup 1 needs to be stable so as not to fall, and the working efficiency and the wrapping quality are seriously influenced.

Disclosure of Invention

The utility model aims to provide a pouring cup positioning seat for lost foam casting of a cup mouth film, which has the advantages of simple structure, low manufacturing cost, convenience and high efficiency in operation, and solves the problems that the working efficiency is low and the film coating quality cannot be ensured when the operation of wrapping the film at the cup mouth of a pouring cup is carried out in the prior art.

In order to achieve the above purpose, the utility model comprises a concrete body 7 and a plastic barrel 6; a pit is arranged in the middle of the concrete body 7, and the shape of the pit is matched with the cylindrical small end of the pouring cup 1 and the middle lower part of the middle circular truncated cone; the plastic barrel 6 is used for containing a concrete body 7, and the plastic barrel and the concrete body are adhered together.

The manufacturing method of the pouring cup positioning seat for lost foam casting of the cup opening coated film comprises the following steps:

1. manufacturing a tire mold: firstly, taking a pouring cup 1, cutting a foam wafer 4, bonding the foam wafer 4 by using hot melt adhesive to seal a small end opening of the pouring cup 1, and then wrapping the seam by using adhesive tape for two circles to enable the seam to be smooth; and then dip-coating the small-end cylindrical section and the circular truncated cone section of the sprue cup 1 with paint and drying twice to form a forming die 8 for later use.

2. A plastic barrel 6 filled with repair paste by a lost foam is taken.

3. And blending and stirring cement mortar according to the needs.

4. A certain amount of cement mortar is put into the bottom of the plastic barrel 6, the height is 60-100mm, and the middle part is leveled.

5. The small end of the prepared tire mold 8 is placed downwards and in the middle into a plastic barrel, cement mortar is paved on the plastic barrel, and 2/3 of the circular truncated cone inclined plane section of the pouring cup 1 is positioned below the upper edge of the barrel opening.

6. And (4) supporting the moulding bed 8, pouring the rest cement mortar into the plastic barrel 6 along the periphery of the moulding bed, and leveling the surface.

7. A brick is flatly pressed at the big end of the pouring cup 1 to prevent the moulding bed from floating.

8. And (5) placing for more than 5 days, after the cement mortar is completely hardened, removing the moulding bed 8, and thus obtaining the pouring cup positioning seat.

The supporting plate tool for cutting the bevel edge of the large foam plate has the following effects:

1. the cement and sand used for manufacturing are not large, and can be obtained from the construction site in a factory; other used materials can be obtained in the lost foam workshop, and the manufacturing is simple and convenient, and the cost is low.

2. The use and the operation are convenient and efficient, the application effect is obvious, the firmness and the durability are realized, and the production efficiency is greatly improved.
