Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a heat-insulating side mold of a large-displacement wheel hub mold. Background Art

[0002] For the casting of large-displacement wheels, the volume of the mold used is larger than that of ordinary molds. This results in the mold wall thickness of the original side mold close to the riser side being thicker, which absorbs more heat from the riser, causing the riser to solidify faster, affecting the riser's ability to compensate for the shrinkage of the rim. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies of the prior art and provide a heat-insulating side mold for a large-displacement wheel hub mold.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a heat-insulating side mold of a large-displacement wheel hub mold, comprising a plurality of side modules. A first groove is provided on the outer side of the side module, a second groove is provided on the upper part of the side module, and heat-insulating cotton is arranged in the second groove.

[0006] Furthermore, the lower end of the second groove is connected to the first groove.

[0007] Furthermore, at least a portion of the thermal insulation cotton is located in the first groove.

[0008] Furthermore, there are at least two grooves.

[0009] Furthermore, a sealing plate is provided above the second groove, and the sealing plate and the side module are welded.

[0010] The beneficial effects of the utility model are:

[0011] 1. Block the heat dissipation path of the riser by opening the second groove;

[0012] 2. Install insulation cotton in groove 2 to increase the mold temperature at the riser. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As attached Figure 1 -Attached Figure 2 As shown, a heat-insulating side mold of a large-displacement wheel hub mold includes a plurality of side modules 1. The plurality of side modules 1 are spliced ​​together to form a complete side mold. A groove 2 is provided on the outer side of the side module 1 to reduce the wall thickness, thereby reducing the heat absorption at the riser.

[0018] A groove 2 3 is provided on the upper part of the side module 1. The groove 3 is milled from the top surface of the side module 1 to the groove 2 below, so that the lower end of the groove 3 is connected to the groove 2. The groove 2 3 blocks the heat dissipation path of the riser. Insulation cotton 4 is arranged in the groove 2 3. At least a part of the insulation cotton 4 is located in the groove 2. The insulation cotton 4 plays a role of heat preservation and can enhance the mold temperature at the riser.

[0019] Furthermore, at least two grooves 2 are provided, so that there is a gap between the grooves 2, and the gap can support the thermal insulation cotton in the groove 2 3 and prevent the thermal insulation cotton from falling.

[0020] Furthermore, a sealing plate 5 is provided above the groove 2 3. The sealing plate 5 is a thin iron plate. The sealing plate 5 and the side module 1 are fixed by spot welding. The sealing plate 5 can completely cover the groove 2 3, thereby preventing the entry of aluminum water. The sealing plate 5 can also press the thermal insulation cotton tightly, so that the thermal insulation cotton fills the groove 2 3 and the thermal insulation cotton is not easy to fall off.

[0021] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
