Abstract
The utility model relates to the technical field of smelting, and in particular relates to a lost foam with a cast cavity. The lost foam comprises a lost foam body made from plastic pellets and is characterized in that the cavity is arranged in the lost foam; the plastic pellets are arranged around the cavity; and the cavity is spherical, ovate or square. The lost foam with the structure has the advantages of saving raw materials and improving product quality.
Description
Technical field
The utility model relates to technical field of smelting, relates to a kind of evaporative pattern.
Background technology
Evaporative pattern is that the foamed plastic grain is made, in the prior art, the part of pouring molten iron all is the disappearance die body, namely pouring molten iron partly has been full of the foamed plastic grain, and in the process of cast, the foamed plastic grain becomes gas overflowing, plastic pellet gases many, that overflow are just many, these gases can affect the quality of product, in addition, use more plastic pellet also can cause waste.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and a kind of evaporative pattern with cast hollow chamber of saving raw material, can improving the quality of products is provided.
The technical solution of the utility model is achieved in that the evaporative pattern with cast hollow chamber, comprise the disappearance die body, the disappearance die body is that plastic pellet is made, and it is characterized in that: have cavity in described disappearance die body inside, all have plastic pellet around the described cavity.
Say that further described cavity is spherical, avette or square.
Perhaps described cavity is the shape of a plurality of square combinations.
The beneficial effects of the utility model are: the evaporative pattern of this spline structure has the advantage that can save raw material, improve the quality of products.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, the shape of disappearance die body 2, cavity 3, spherical 4, avette by 5, a plurality of square combinations.
Specific embodiments:
Below in conjunction with accompanying drawing the utility model is further described.
As described in Figure 1, have the evaporative pattern in cast hollow chamber, comprise disappearance die body 1, disappearance die body 1 is that plastic pellet is made, and it is characterized in that: have cavity 2 in described disappearance die body 1 inside, all have plastic pellet around the described cavity 2.
Say that further described cavity 2 is spherical 3, avette 4 or square.
Perhaps described cavity is the shape 5 of a plurality of square combinations.
Claims (2)
1. the evaporative pattern that has the cast hollow chamber comprises the disappearance die body, and the disappearance die body is that plastic pellet is made, and it is characterized in that: have cavity in described disappearance die body inside, all have plastic pellet around the described cavity.
2. evaporative pattern according to claim 1 is characterized in that: described cavity is spherical or square.
