Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a vertical slag bag structure for use in the island section during shell die casting. Background Technology

[0002] The product cavity is designed to fit the shape of the shell. Liquid metal is injected into the product cavity through the flow channel. After solidification, the product will be formed. The shell is then removed by parting.

[0003] However, the current problem is that during the die casting production process, some machined surfaces cannot be slag-filled and discharged due to structural reasons, resulting in more porosity and shrinkage cavities on local machined surfaces, and making it easy to cause batch scrapping.

[0004] The machined surface of the product may have air holes due to its location or non-parting surface, which will lead to substandard product strength and affect product quality. Therefore, it is necessary to improve it. Utility Model Content

[0005] This utility model provides a vertical slag bag structure for use on isolated areas during die casting of a shell. This structure allows for the installation of slag bags on specific processing surfaces, ensuring that cold material and gas at the front end of the molten metal enter the vertical slag bag during die casting, thus guaranteeing product quality and preventing porosity. It solves the technical problems of existing die casting equipment having a simple structure, making it inconvenient to install slag bags on isolated product islands not on the parting surface, leading to localized porosity and affecting product quality and strength.

[0006] The above-mentioned technical problem of this utility model is solved by the following technical solution: a vertical slag bag structure for islands in shell die casting, comprising a die casting cavity composed of several sliders, a product being die-cast in the die casting cavity, a vertical slag bag being formed at the island of the product, a slag bag cavity corresponding to the vertical slag bag being reserved in the die casting cavity, and a detachable insert being provided in the slider, into which the vertical slag bag can be embedded. During the die casting process, molten metal is injected into the die casting cavity through a material cylinder, and the molten metal cools to form a casting; since some islands on the shell are not on the parting surface, conventional slag bags cannot be set, which will lead to phenomena such as porosity; in this utility model, a vertical slag bag is formed on the islands on the surface of the casting shell that are not on the parting surface, which guides the cold material and gas at the front end of the molten metal into the vertical slag bag during the die casting process, and the slag bag can be removed after parting; the slider in this utility model is equipped with an insert, which is detachable, to prevent the vertical slag bag from being unable to detach from the slider during the parting process, only the insert and the vertical slag bag need to be detached, without affecting the operation of the slider.

[0007] Preferably, the connection between the vertical slag bag and the product is chamfered. The chamfered design at the connection between the vertical slag bag and the product in this invention prevents damage to the product during slag bag removal. Any remaining parts after the vertical slag bag breaks can be removed by machining to remove any marks from the bag.

[0008] Preferably, the vertical slag bag is provided with a draft angle. The draft angle of the vertical slag bag can be adjusted according to the actual situation. The purpose of the draft angle is to facilitate demolding and to fit the vertical slag bag into the insert.

[0009] Preferably, the draft die of the vertical slag bag is a conical structure. The vertical slag bag can be cylindrical, spherical, or polygonal; this invention will use a conical vertical slag bag as an example for illustration.

[0010] Preferably, the insert is a circular sleeve structure installed inside the slider. The insert is detachable, and the vertical slag bag is embedded within the insert. The slider in this invention has an insert that is detachable. This is to prevent the vertical slag bag from becoming stuck with the slider during the parting process; simply detaching the insert and the vertical slag bag separately does not affect the operation of the slider.

[0011] Therefore, the vertical slag bag structure of this utility model for use in the island of shell die casting has the following advantages: slag bags can be set on some special processing surfaces to ensure that the cold material and gas at the front end of the molten metal enter the vertical slag bag during the die casting process, thus ensuring product quality and avoiding porosity and other issues.

[0020] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1 and 2 As shown in Figures 3, 4, 5, 6, and 7, a vertical slag bag structure for an island in a die-casting shell includes a die-casting cavity composed of several sliders 1, a product 4 is die-cast in the die-casting cavity, a vertical slag bag 2 is formed on the island on the surface of the product 4, and a slag bag cavity corresponding to the vertical slag bag 2 is reserved in the die-casting cavity.

[0023] An insert 3 is installed inside the slider 1. The insert 3 is a circular sleeve structure installed inside the slider 1, and the insert 3 is detachable. The vertical slag bag 2 is embedded in the insert 3.

[0024] The vertical slag bag 2 and the surface of the product 4 are connected by a chamfer, which is inclined towards the "middle". The overall structure of the vertical slag bag 2 is provided with a draft angle, and the draft of the vertical slag bag 2 is a "conical" structure.

[0025] The vertical slag bag 2 can be a cylindrical, spherical, or polygonal structure.

[0026] During the die casting process, molten metal is injected into the die casting cavity through a material cylinder, and the molten metal cools to form a casting. Since some islands on the shell are not on the parting surface, conventional slag pockets cannot be set, which can lead to phenomena such as porosity.

[0027] In this invention, a vertical slag bag 2 is formed on an island on the surface of the casting shell that is not on the parting surface. During the die casting process, the cold material and gas at the front end of the molten metal are guided into the vertical slag bag 2. The slag bag can be removed after parting.

[0028] The slider 1 of this utility model is equipped with an insert 3. The insert 3 is detachable. Its function is to prevent the vertical slag bag 2 from being unable to detach from the slider 1 during the separation process. Only the insert 3 and the vertical slag bag 2 need to be detached separately, which does not affect the operation of the slider 1.

[0029] The vertical slag bag 2 and the product 4 in this utility model are designed with a chamfer at the connection point. This can avoid damaging the product 4 when removing the slag bag. The remaining part after the vertical slag bag 2 breaks can be removed by mechanical processing to remove the mark of the vertical slag bag 2. The overall draft angle of the vertical slag bag 2 can be adjusted according to the actual situation. The draft function of the vertical slag bag 2 is to facilitate demolding.

[0030] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
