Benefits of technology

[0012] 1. This gravity tilting casting mold for thin-walled aluminum alloy parts, through its mold structure and anti-deformation process, allows molten aluminum to be poured into the pouring cup during use. At this time, the device tilts 90 degrees, and the molten aluminum flows into the product mold body from the middle connecting port and the left and right inner gates on both sides. When the product mold body rotates to the 0-degree horizontal direction, the top anti-deformation process gate is filled, and the molten aluminum is punched. Due to the left and right inner gates on both sides, the molten aluminum flows into the inner cavity of the product mold body quickly, allowing the thin-walled part of the product to be punched quickly, avoiding air entrapment. This effectively solves the problem of cold shuts, shrinkage, and leakage defects caused by poor flow of molten aluminum in thin-walled parts. At the same time, the top anti-deformation process gate design allows the thin-walled part at the top of the product to be punched quickly, and also ensures that the product does not deform during the cooling process.

Description

Technical Field

[0001] This utility model relates to the field of gravity tilting casting technology, specifically a gravity tilting casting mold for thin-walled aluminum alloy parts. Background Technology

[0002] Gravity casting refers to the process of pouring molten metal into a mold under the influence of Earth's gravity; it is also known as gravity pouring. In a broad sense, gravity casting includes sand casting, metal mold casting, investment casting, lost foam casting, and clay casting; in a narrow sense, gravity casting mainly refers to metal mold casting.

[0003] Thin-walled aluminum alloy castings are complex products. Due to their thin walls, gravity casting is used, but the flow rate of molten aluminum is slow in the thin-walled areas, which easily leads to cold shuts and perforations. During the cooling process, shrinkage and deformation defects also occur. Based on the shortcomings of existing technology, this utility model designs a gravity tilting casting mold for thin-walled aluminum alloy parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gravity tilting casting mold for thin-walled aluminum alloy parts, which effectively solves the casting defects of cold shuts, shrinkage porosity, and product cooling deformation in thin-walled products.

[0006] As a preferred embodiment of this utility model, the four corners of the outer surface of the pouring cup are provided with rounded corners, and the connecting port is connected to the pouring cup.

[0007] As a preferred embodiment of this utility model, an air hole is provided on one side of the outer surface of the product mold, and an arc-shaped shell is provided on the outer surface of the product mold.

[0010] As a preferred embodiment of this utility model, an irregularly shaped shell is fixedly installed on the outer surface of the product mold, and the irregularly shaped shell is connected to the interior of the product mold.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This gravity tilting casting mold for thin-walled aluminum alloy parts, through its mold structure and anti-deformation process, allows molten aluminum to be poured into the pouring cup during use. At this time, the device tilts 90 degrees, and the molten aluminum flows into the product mold body from the middle connecting port and the left and right inner gates on both sides. When the product mold body rotates to the 0-degree horizontal direction, the top anti-deformation process gate is filled, and the molten aluminum is punched. Due to the left and right inner gates on both sides, the molten aluminum flows into the inner cavity of the product mold body quickly, allowing the thin-walled part of the product to be punched quickly, avoiding air entrapment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2A gravity tilting casting mold for thin-walled aluminum alloy parts includes a pouring cup 1, a connecting port 2 fixedly installed on one side of the pouring cup 1, and a mold structure 3 fixedly installed at the opening of the connecting port 2 by bolts; the mold structure 3 includes a product mold 31, a left inner sprue 32 fixedly installed on one side of the product mold 31, the left inner sprue 32 communicating with the connecting port 2, a right inner sprue 33 fixedly installed on the other side of the outer surface of the product mold 31, the right inner sprue 33 communicating with the connecting port 2, and an anti-deformation process bracket 4 provided at the end of the product mold 31, the anti-deformation process bracket 4 communicating with the interior of the product mold 31.

[0018] Please see Figure 1 The outer surface of the pouring cup 1 has rounded corners 101 at its four corners, and the connecting port 2 is connected to the pouring cup 1. One side of the outer surface of the product mold 31 has an air hole 34, and the outer surface of the product mold 31 has an arc-shaped shell 35. Both sides of the product mold 31 have circular portions 36, which are connected to the anti-deformation process bracket 4. An inner groove 37 is formed between the two circular portions 36. A non-circular shell 38 is fixedly installed on the outer surface of the product mold 31, and the non-circular shell 38 is connected to the interior of the product mold 31.

[0019] The rounded corners 101 are designed to prevent scratches when personnel come into contact with the device. The curved shell 35, the round part 36, and the irregularly shaped shell 38 can be filled with molten aluminum when the device is tilted, avoiding casting dead corners.

[0020] Working principle: When a gravity tilting casting mold for a thin-walled aluminum alloy part is used, the device is horizontal in normal condition. When the device is in use, molten aluminum is poured into the pouring cup 1. At this time, the device is tilted 90 degrees, and the molten aluminum flows into the product mold 31 from the middle connecting port 2 and the left and right inner gates 32 and 33 on both sides. When the product mold 31 is rotated to the 0-degree horizontal position, the top anti-deformation process gate 4 is filled, and the molten aluminum is punched. After solidification time of 150-160 seconds, the part is removed. Due to the left and right inner gates 32 and 33 on both sides, the molten aluminum flows into the inner cavity of the product mold 31 quickly, which makes the thin-walled part of the product punched quickly, avoiding air entrapment. This effectively solves the problem of cold shuts, shrinkage and leakage defects caused by poor flow of molten aluminum when the thin-walled part is thin. At the same time, the top anti-deformation process gate 4 is designed to make the thin-walled part of the product punched quickly, and also ensures that the product does not deform during the cooling process.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
