Abstract
The utility model belongs to lost foam casting accessory technical field, is specifically related to a kind of compound runner cup for lost foam casting.The utility model mainly solves existing runner cup for lost foam casting and has that cup cavity wall abrasion resistance is low, casting pouring time easily enter sand and the loaded down with trivial details technical problem of production process.The technical solution adopted in the utility model is: a kind of compound runner cup for lost foam casting, comprises main cup and sand cover.The utility model has that glass cavity wall abrasion resistance is strong, casting pouring time not easily enter sand and the simple advantage of production process.
Description
Technical field
The utility model belongs to lost foam casting accessory technical field, is specifically related to a kind of compound runner cup for lost foam casting.
Background technology
At present, making runner cup for lost foam casting by hand often adopts white mould to be slit into funnel shaped, again by bonding for the sprue of white mould cup and 1/3 length, be coated with cast paint post-drying, still need before cast again dope layer to be pushed aside to carry out with 2/3 length sprue other on model secondary bonding after can use; Or surround cylindrical with iron sheet, filled with water hyaline-quartz sand also makes funnel shaped, and inner wall of hopper will be lighted by brush alcohol-base foundry coating, place fibrous filter net and wad shutoff cup periphery gap with sprue interface.But cast model is often too much because of sprue interface, and cup cavity wall abrasion resistance is low, makes operation by hand loaded down with trivial details, easily cause during casting pouring and enter sand, and quality is also difficult to obtain guarantee.
Summary of the invention
The purpose of this utility model be solve that existing runner cup for lost foam casting exists that cup cavity wall abrasion resistance is low, casting pouring time easily enter sand and the loaded down with trivial details technical problem of production process, a kind of compound runner cup for lost foam casting is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of compound runner cup for lost foam casting, comprise main cup and sand cover, wherein: described main cup is cylinder, truncated cone cast gate is provided with on the top of main cup inner chamber, fire resistant heat preserving coating is provided with at the inwall of truncated cone cast gate, be provided with cylindrical running channel in the bottom of main cup inner chamber and be communicated with truncated cone cast gate, be provided with truncated cone detent in the lower end of main cup and be communicated with cylindrical running channel; Described sand cover is cylinder and bottom by top is that frustum of a cone body forms, the external diameter of sand cover and the diameter of upper circular cone table top of truncated cone detent match and sand overlaps and embeds in truncated cone detent, sand cover is provided with cylindrical hole and makes the diameter of cylindrical hole identical with the diameter of sprue, sand cover is enclosed within the upper end of sprue.
Compared with background technology, the utility model has the following advantages:
1) the utility model intensity is high, and resistance to elevated temperatures is high, and capacity is large, can effectively prevent molten metal from washing out and burning out cup when cup poured into by pouring ladle, and molten metal is not easily excessive;
2) the main cup section of cup adopts truncated cone cast gate, can round and smooth smooth transition when molten metal pours cup into from pouring ladle, does not produce resistance to the inflow of molten metal;
3) fire resistant heat preserving coating is provided with at the inwall of main cup truncated cone cast gate, sand washing defect when solving cast;
4) main bottom of cup and sand use embedded truncated cone detent to closely cooperate between overlapping, and can effectively prevent negative pressure to be drawn into molding sand, solve sprue and cup connecting interface is many, the problem of Yi Jinsha;
5) the main cup of the utility model has certain weight, can overcome molten iron buoyancy, ensures molten steel quality;
6) the utility model use and operate all convenient, and with low cost.
accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention
As shown in drawings, the compound runner cup for lost foam casting of one in the present embodiment, comprise main cup 1 and sand cover 4, wherein: described main cup 1 is cylinder, truncated cone cast gate is provided with on the top of main cup 1 inner chamber, be provided with fire resistant heat preserving coating 2 at the inwall of truncated cone cast gate, be provided with cylindrical running channel in the bottom of main cup 1 inner chamber and be communicated with truncated cone cast gate, be provided with truncated cone detent 3 in the lower end of main cup 1 and be communicated with cylindrical running channel; Described sand cover 4 is cylinder and bottom by top is that frustum of a cone body forms, the diameter that sand overlaps the external diameter of 4 cylinders and the upper circular cone table top of truncated cone detent 3 matches and sand overlaps 4 embeds in truncated cone detent 3, sand cover 4 is provided with cylindrical hole and makes the diameter of cylindrical hole identical with the diameter of sprue 5, sand cover 4 is enclosed within the upper end of sprue 5.
After cast, main cup is easily separated with sandbox molding sand with sand cover, convenient to use.
