Description
Technical Field
The utility model relates to a wheel casting field, specific wheel casting mould that says so relates to.
Background
At present, tire pressure sensors are more and more widely applied in various automobile manufacturers, especially some high-end automobile models are basically configured as standards, the balance state of the original wheel structure is damaged by the use of the sensors, so that the balancing needs to be carried out again, and a commonly used method is to design a balancing casting nest at an outer wheel well, however, the wheel structure is easy to cause problems in casting production, and practice shows that defects such as shrinkage porosity, air holes and the like exist nearby the casting nest, mainly because the existence of the casting nest enables a molten aluminum flow channel to become quite narrow, so that the position of a rim at the upper end of the casting nest is very difficult to be fed, and thus the shrinkage porosity is easy to occur; in addition, due to the blocking of the mold precasting table, the gas in the cavity is discharged very unsmoothly, and is continuously gathered at the lower end of the casting nest, so that the defect of air holes is easily generated at the outer rim, the forming quality of the wheel is seriously influenced, and the yield is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art, and provides an improved aluminum alloy wheel low-pressure casting die, and the novel structure can effectively solve the problem of insufficient feeding capacity of a balancing nest position, thereby reducing the occurrence of shrinkage porosity defects; by reducing the accumulation of gas at this location, the outer rim porosity problem is solved and ultimately the occurrence of casting waste is reduced.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a wheel casting mould, includes top mould, die block, side forms, top mould, die block, side forms constitute mould cavity, its characterized in that jointly: the side forms inboard corresponds wheel well department processing precasting boss, precasting boss surface sets up the gas storage material that is used for saving the gas that is hindered, the side forms back of the body chamber corresponds casts nest position and the processing of top mould inner chamber correspondence nest position has the groove of following shape, slows down temperature loss.
Furthermore, the following groove is internally provided with heat preservation asbestos.
Furthermore, the distance between the top die and the bottom of the groove is 10-20mm from the molded surface.
Furthermore, the distance between the back cavity of the side mold and the bottom of the groove is 20-30mm from the molded surface.
Furthermore, the gas storage material is a coating with good heat preservation and gas storage effects.
Further, the thickness of the coating layer is 40-60 um.
Compared with the prior art, the utility model has the advantages of: the utility model has simple structure, and can effectively improve the mold temperature in the area by processing the following groove at the position of the top mold and the side mold back cavity corresponding to the casting nest and filling heat preservation asbestos in the following groove, thereby making up the problem of insufficient feeding capacity caused by narrow molding and eliminating the shrinkage porosity defect of the rim at the front end of the casting nest; by coating the surface of the precast boss with the coating with good heat preservation and gas storage effects, the gas with blocked discharge can be stored in the coating, and the problem of outer rim pores is reduced.

Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The technical solution of the present invention will be described more clearly and completely with reference to the accompanying drawings, in which embodiments of the invention are shown and described. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The following describes a wheel casting mold according to an embodiment of the present invention with reference to the drawings.
Figure 1 is the wheel structure after carrying out the trim with tire pressure sensor, and the nest is cast in the design trim in outside wheel well department promptly, the utility model discloses lie in improving near a series of defect problems of casting the nest in current casting process.
As shown in fig. 2, a wheel casting mold, wherein a top mold 1, a bottom mold 3 and a side mold 2 together form a cavity of the mold to complete solidification forming of a wheel casting; processing a pre-cast boss 7 at a position corresponding to a wheel well on the inner side of the side die 2 for forming a casting nest shape of the wheel; a following groove 6 is milled at the position of the inner cavity of the top die 1 corresponding to the casting nest, the width size is consistent with the casting nest, the distance between the groove bottom and the molded surface is 10-20mm, and heat-preservation asbestos 5 is filled in the groove, so that the temperature loss of the top die 1 at the position of the casting nest is reduced; the temperature of the die in the area is effectively increased, a conformal groove 6 is processed at the position of the back cavity of the side die 2 corresponding to the casting nest, the width dimension is consistent with that of the casting nest, the distance between the bottom of the groove and the molded surface is 20-30mm, and the interior of the groove is filled with heat-preservation asbestos 5, so that the temperature of the position of the side die 2 is increased; the surface of the pre-cast boss 7 of the side die 2 is provided with the gas storage material 4, the gas storage material 4 can be coated with paint with good heat preservation and gas storage effects, the thickness is 40-60 mu m, so that gathered gas can be stored, and the gas with blocked discharge can be stored in the gas storage material, so that the occurrence of gas hole defects is reduced.
Compared with the prior art, the utility model has the advantages of: the utility model has simple structure, and can effectively improve the mold temperature in the area by processing the following groove at the position of the top mold and the side mold back cavity corresponding to the casting nest and filling heat preservation asbestos in the following groove, thereby making up the problem of insufficient feeding capacity caused by narrow molding and eliminating the shrinkage porosity defect of the rim at the front end of the casting nest; by coating the coating with good heat preservation and gas storage effects on the surface of the precast boss, the gas with blocked discharge can be stored in the coating, and the problem of outer rim pores is reduced.
