Abstract

The utility model provides a hollow structure wax matrix that thick major possession of production was used, include by the upper cover and with the hollow structure wax matrix that the corresponding main part of upper cover constitutes, upper cover top central point puts and sets up hollow runner, and hollow runner is hollow cuboid structure, and the main part is thin wall box structure, and the top of the thin wall of main part sets up inside sunken cooperation and ends, and the thickness of thin wall is 5mm to central point at the bottom surface II of main part puts and sets up the characters. Because the wall thickness of the wax mould is greatly reduced, the sinking degree of the wax mould is correspondingly greatly reduced to almost no extent, and the sinking defect does not need to be repaired manually; the integral solid wax pattern is changed into the wax pattern with a thin-wall structure combined by the upper cover and the main body, so that the consumption of the raw material of the wax pattern and the energy consumption during dewaxing are saved.

Description

Hollow structure wax mould for producing thick and large parts
Technical Field
The utility model relates to a hollow structure wax matrix, in particular to hollow structure wax matrix that thick major possession of production was used.
Background
Pressing a wax pattern is the first step of investment casting, and the wax pattern shrinks volumetrically from pressing to cooling, which is reflected in size reduction, but the size reduction degree of different parts is different due to structural influence. The thick part of the wax pattern has the rule that the size shrinkage from the edge to the center is gradually increased, and the final result is that the surface of the wax pattern has a concave defect. Since the shape of the wax pattern is the same as that of the casting, if the surface of the wax pattern is not treated for the dishing defect, the dishing defect also occurs on the surface of the casting. For castings with strict surface shape requirements, the occurrence of surface depressions is not allowed. The existing treatment method is to repair the depression on the surface of the wax mould manually. However, the manual repair of the surface of the wax pattern can not meet the requirement of accurate dimension, the repair material can also pollute the raw material of the wax pattern, and the surface structure is complicated and delicate and can not be repaired manually.
Disclosure of Invention
The utility model discloses a remedy prior art not enough, provide a hollow structure wax matrix that thick major possession of production was used.
The utility model discloses a realize through following technical scheme: the utility model provides a hollow structure wax matrix that thick major possession of production was used, includes the hollow structure wax matrix of constituteing by upper cover and the corresponding main part of upper cover, upper cover top central point puts and sets up hollow runner, the main part is thin wall box structure, and the top of the thin wall of main part sets up inside sunken cooperation and ends.
Preferably, the hollow gate is of a hollow cuboid structure.
Preferably, the bottom surface I and the top surface I of the upper cover and the bottom surface II and the top surface II of the main body are octagonal structures which have the same size and are parallel to each other.
Preferably, the thickness of the upper cover is the same as the height of the matching seam allowance.
Preferably, characters are arranged at the center of the bottom surface II of the main body.
Preferably, the thin wall of the body has a thickness of 5 mm.
Compare earlier with prior art, the beneficial effects of the utility model are that: the main body of the wax mould is of a thin-wall box structure, and the wall thickness of the wax mould is greatly reduced, so that the sinking degree of the wax mould is correspondingly greatly reduced to almost no extent, and the sinking defect does not need to be repaired manually; the integral solid wax pattern is changed into the wax pattern with a thin-wall structure combined by the upper cover and the main body, so that the consumption of the raw material of the wax pattern and the energy consumption during dewaxing are saved.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of a wax pattern of the present invention;
FIG. 2 is a schematic structural view of the upper cover of the present invention;
FIG. 3 is a schematic structural view of the main body of the present invention;
fig. 4 is a schematic structural view of a wax pattern in the prior art.
In the figure, 1, a wax mold, 2, an upper cover, 3, a main body, 4, a hollow pouring gate, 5, a thin wall, 6, a matching stopper, 7, a bottom surface I, 8, a top surface I, 9, a bottom surface II, 10 and a top surface II.
Detailed Description
As shown in FIG. 4, the wax pattern of the prior art is a thick solid body with a wall thickness of 57.15mm and a weight of 646 grams. The use of a solid wax pattern does not avoid the dishing of the wax pattern and the surface of the wax pattern is obscured by the dishing.
The utility model discloses an embodiment is exactly to prior art, the improvement that sunken defect was made appears easily in the wax matrix surface. The following detailed description is provided for illustrative embodiments.
As shown in fig. 1, 2 and 3, the hollow structure wax mold for producing thick and large parts comprises an upper cover 2 and a main body 3 corresponding to the upper cover 2, wherein a hollow sprue 4 is arranged at the center of the top of the upper cover 2, the main body 3 is of a thin-wall box structure, and an inwardly concave matching stopper 6 is arranged at the top end of a thin wall 5 of the main body 3. The hollow sprue 4 is a hollow cuboid structure, the bottom surface I7 and the top surface I8 of the upper cover 2, the bottom surface II 9 and the top surface II 10 of the main body 3 are octagonal structures which are identical in size and parallel to each other, the thickness of the upper cover 2 is identical to the height of the matching stopper 6, and meanwhile characters are arranged at the center of the bottom surface II 9 of the main body 3. In the embodiment, the thickness of the thin wall 5 is 5mm, compared with the wall thickness of the wax mold 57.15mm in the prior art, the wall thickness is less than eleven times of the original wall thickness, the sinking degree of the wax mold is correspondingly reduced to eleven times of the original wall thickness, the sinking of the wax mold is almost not generated, and the sinking defect does not need to be repaired manually.
The upper cover 2 and the main body 3 are respectively pressed, the seam allowance part of the matching seam allowance 6 is coated with a bonding agent in advance after cooling, the upper cover 2 and the main body 3 are matched together through the seam allowance of the matching seam allowance 6, and due to the bonding agent, the upper cover 2 and the main body 3 can be combined into a firm integral wax mold 1. The weight of the wax pattern in the embodiment is 227 g, and compared with the weight of 646 g in the prior art, the wax pattern saves the consumption of raw materials of the wax pattern and the energy consumption during dewaxing.
The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made to the present invention by using the design concept shall fall within the scope of infringing the present invention.
