Abstract
The utility model relates to the technical field of wax molds, in particular to a wax mold for a rear axle lower thrust support, which comprises a U-shaped mounting groove, wherein the back surface of the mounting groove is provided with an ear part, and a cold iron is arranged at the position of a hole to be processed of the ear part. According to the utility model, the chill is preset on the wax mould, so that shrinkage holes are prevented from occurring during pouring, and the process is simple and practical.
Description
Technical Field
The utility model relates to the technical field of wax molds, in particular to a wax mold for a rear axle lower thrust support.
Background
The shape and structure of a workpiece cast by a wax mould depend on the wax mould, and when the workpiece is poured after wax melting, the cooling rate of each part is inconsistent because the thickness of each part of the workpiece is inconsistent, and after-cooling of thicker parts can easily form shrinkage holes due to the lack of molten metal.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a wax mould for a rear axle lower thrust support, which is provided with a chill at a thicker part of the wax mould so as to accelerate the cooling speed of the part, and the chill is melted after the molten metal is heated and is also used as a filling molten metal so as to prevent shrinkage cavities.
The technical scheme adopted for solving the technical problems is as follows: a wax matrix for thrust support under rear axle, including being "U" font mounting groove, the back of mounting groove is provided with the ear, the position that the hole was treated to the ear is provided with the chill.
Further, at least three foot pads are arranged at the bottom of the mounting groove.
Further, the bottom of the mounting groove is provided with long holes penetrating through the bottom of the mounting groove, the number of the pad feet is four, and the pad feet are distributed around the long holes in a rectangular shape.
Further, the length of the chill is greater than the thickness of the lug, and the two ends of the chill protrude out of the lug.
Further, a pouring cup is arranged between the two lugs, and the bottom of the pouring cup is communicated with the two lugs through an inner pouring gate; and a riser is arranged at the top of each of the two lugs.
The beneficial effects of the utility model are as follows: a wax matrix for thrust support under rear axle, it is including being "U" font mounting groove, the back of mounting groove is provided with the ear, the position that the hole is treated to the ear is provided with the chill. According to the utility model, the chill is preset on the wax mould, so that shrinkage holes are prevented from occurring during pouring, and the process is simple and practical.

Detailed Description
The utility model will now be described in further detail with reference to the drawings and the specific embodiments, without limiting the scope of the utility model.
As shown in fig. 1-3, the wax pattern for the rear axle lower thrust support of the embodiment comprises a U-shaped mounting groove 1, wherein an ear part 2 is arranged on the back surface of the mounting groove 1, and a chiller 3 is arranged at a position of a hole to be processed of the ear part 2; in order to facilitate machining of the bottom mounting surface of the mounting groove 1, at least three padding feet 4 are arranged at the bottom of the mounting groove 1, and the heights of all the padding feet 4 are consistent, so that the mounting groove is convenient to assemble a workpiece and stable.
The utility model is used for casting the wax mould of the rear axle lower thrust bearing, and can also be used for other problems for preventing shrinkage cavity during casting. Simple and practical, the both ends length of chill 3 surpasses ear 2 to after the wax matrix melts, the both ends of chill 3 are fixed in the sand shell and can not fall.
The bottom of the mounting groove 1 is provided with long holes 5 penetrating through the bottom of the mounting groove 1, four cushion feet 4 are arranged, and the cushion feet 4 are rectangular and distributed around the long holes 5. The long hole 5 can reduce the weight of the workpiece, and the bottom of the mounting groove 1 is not excessively large in area, so that casting defects are caused.
A pouring cup 6 is arranged between the two lugs 2, and the bottom of the pouring cup 6 is communicated with the two lugs 2 through an inner pouring gate 7; one riser 8 is provided at each top of the two ears 2. Thereby better filling the die cavity with molten metal during pouring.
Finally, it should be noted that the foregoing embodiments are merely for illustrating the technical solution of the present utility model, and the front, rear, left, right, upper, middle, lower, etc. directions adopted for the description of the technical solution are set based on the drawings, not limiting the scope of the present utility model, although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
