Description

A kind of motor model is used the loam core

Technical field

The utility model relates to casting field, specifically the loam core used of motor model.

Background technology

Existing foundry goods needs sandbox with the loam core, and mold thickness is very large, cooperates defective tightness, and fash is many, and is not easy to polishing and the cleaning of foundry goods.

Summary of the invention

The purpose of this utility model is the deficiency that exists for prior art, and the motor model that provides that a kind of mold thickness is little, fash is few and be easy to the casting grinding cleaning is used the loam core.

For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is that a kind of motor model is used the loam core, comprise five loam cores, the centre is the first loam core, tightly surrounded by the second loam core, the 3rd loam core, the 4th loam core and the 5th loam core around the first loam core, described the first loam core is circular loam core, and the 3rd loam core is the loam core, location.

Beneficial effect: the utility model does not need sandbox, reduces mold thickness, has closely reduced fash thereby cooperate, and has been easy to polishing and the cleaning of foundry goods.

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.

As shown in Figure 1, a kind of motor model is used the loam core, comprises five loam cores, is respectively 1, the second loam core 2, the first loam core, the 3rd loam core 3, the 4th loam core 4 and the 5th loam core 5.

The first loam core 1 is circular loam core, and all the other four loam cores all cooperate with the first loam core 1, and the first loam core 1 is tightly surrounded.

During use, at first by 3 location, the 3rd loam core, guarantee the position in loam core, first the 3rd loam core 3 is cooperated closely with the first loam core 1, then by the 3rd loam core 3 the 4th loam core 4 and the second loam core 2 are cooperated with the first loam core 1 and the 3rd loam core 3, at last the 5th loam core 5 is close to.5 loam cores fit in an integral body closely, have greatly reduced fash.
