Description

Technical Field

[0001] This utility model relates to the field of automotive parts casting mold technology, and in particular to automotive seat pelvis mold cavity. Background Technology

[0002] The car seat pelvis is a complex aluminum alloy part that plays an important role in supporting and ensuring passenger safety in car seats. Currently, the production of car seat pelvises mostly adopts traditional casting technology. The production process is as follows: first, a blank part is produced by traditional casting technology, and then it is shaped by multiple machining processes.

[0003] Existing production methods have many drawbacks. Not only are the processes numerous and wasteful of manpower and resources, leading to high production costs and low efficiency, but traditional casting also results in parts with lower strength and a tendency to develop defects such as shrinkage cavities and porosity during the casting process. This makes it difficult to meet the high-quality, high-precision requirements of modern automotive manufacturing. In contrast, the new casting method for producing automotive seat pedestals offers significant advantages. The formed parts have high dimensional accuracy, and in areas without special dimensional requirements, machining is unnecessary to meet dimensional accuracy standards, greatly reducing the number of subsequent machining steps and significantly improving the production efficiency of automotive seat pedestals. Furthermore, the new casting method can achieve automated production, significantly reducing manual labor and effectively lowering production costs. In addition, the new casting method is formed under specific process conditions, and continuous optimization during the forming process can compensate for shrinkage, reducing internal shrinkage cavities and porosity while improving casting strength. Therefore, the new casting method is more suitable for manufacturing parts with high requirements for dimensional accuracy, internal quality, and performance. Utility Model Content

[0004] The purpose of this invention is to provide a mold cavity for an automotive seat pelvis to solve the problems of complex molding processes, low dimensional accuracy, high cost, low productivity, low strength, and easy occurrence of defects such as shrinkage cavities and porosity in existing automotive seat pelvis molding processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold cavity for an automotive seat pelvis, the mold cavity including a sprue sleeve, a sprue, a sub-sprue, a cavity, an overflow groove, and an venting groove, the outside of the cavity being connected to the overflow groove, and part of the overflow groove being connected to the venting groove.

[0006] Preferably, the mold cavity is a single cavity with multiple overflow grooves and venting grooves, which are evenly distributed.

[0007] Preferably, the gating system consists of two sub-gating systems, with the lower end of the gating system connected to the sprue sleeve and the upper end of the gating system connected to the mold cavity.

[0008] Preferably, the ingate at the connection between the gating system and the cavity is a flat ingate.

[0009] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0010] 1. In this utility model, by adopting a design with one mold cavity, multiple overflow grooves and venting grooves evenly distributed, the production efficiency is greatly improved and the production cycle is reduced compared with traditional casting molds while meeting the requirements for casting formability.

[0011] 2. In this utility model, the connection between the gating system and the mold cavity adopts a flat ingate design, which fully considers the shape characteristics and molding capacity of the automotive seat pelvis parts, so that the molten metal can fill the mold cavity more evenly and stably, effectively avoiding problems such as turbulence and air entrapment during the casting process, thereby obtaining high-performance and high-quality castings and reducing the scrap rate.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 As shown, this utility model provides a technical solution: the mold cavity includes a sprue sleeve 1, a sprue 2, a sub-sprue 3, a cavity 4, an overflow groove 5, and an venting groove 6. The outside of the cavity 4 is connected to the overflow groove 5, and part of the overflow groove 5 is connected to the venting groove 6.

[0017] The effect achieved by the entire embodiment 1 is as follows: by reasonably setting the connection relationship of the sprue sleeve 1, sprue 2, sub-sprue 3, cavity 4, overflow groove 5 and venting groove 6, a complete channel for molten metal flow and gas discharge is constructed, which provides a basic guarantee for casting forming, so that the molten metal can smoothly fill the cavity 4, and at the same time discharge the gas in the cavity 4, reducing the generation of defects such as porosity inside the casting.

[0018] Example 2: Figure 1 As shown, this utility model provides a technical solution: the mold cavity is a single cavity mold with multiple overflow grooves 5 and venting grooves 6, which are evenly distributed;

[0019] The overall effect of Embodiment 2 is as follows: the traditional one-cavity mold for casting is improved to a one-cavity mold with multiple overflow grooves 5 and venting grooves 6 evenly distributed, while meeting the filling and performance requirements. In a single casting process, the gas and excess molten metal in the cavity 4 can be discharged more effectively, further reducing defects such as shrinkage cavities, porosity and gas holes in the casting. At the same time, the production efficiency is improved. Compared with traditional molds, more qualified castings can be produced per unit time.

[0020] Example 3: As Figure 1 As shown, this utility model provides a technical solution: the gating system 2 is composed of two sub-gating systems 3, the lower end of the gating system 2 is connected to the gating sleeve 1, the upper end of the gating system 2 is connected to the cavity 4, and the ingate at the connection between the gating system 2 and the cavity 4 adopts a flat ingate.

[0021] The overall effect achieved by embodiment 3 is as follows: the design of the gating system 2 and the ingate combines the structural characteristics of the automotive seat pelvis parts and meets the filling capacity of the casting. The flat ingate allows the molten metal to spread more evenly when it enters the cavity 4, avoiding the scouring and wear caused by the molten metal directly impacting the cavity 4 wall. At the same time, it ensures that the molten metal flows smoothly in the cavity 4, which is conducive to obtaining castings with better molding quality and higher dimensional accuracy.

[0022] The working principle of the entire equipment is as follows: The car seat pelvis mold adopts a single-cavity design with multiple overflow channels 5 and venting channels 6 evenly distributed. The sprue 2 consists of two sub-sprues 3, with the lower end connected to the sprue sleeve 1 and the upper end connected to the mold cavity 4. The outside of the cavity 4 is connected to the overflow channels 5, and part of the overflow channels 5 is connected to the venting channels 6. During the casting process, the molten metal enters the sprue 2 through the sprue sleeve 1 and then flows into the cavity 4 through the sub-sprues 3. Due to the use of a flat ingate, the molten metal can fill the cavity 4 evenly and stably. During the filling process, the gas in the cavity 4 is discharged from the mold cavity through the overflow channels 5 and venting channels 6, avoiding gas residue that could form defects such as porosity. At the same time, excess molten metal can also be discharged through the overflow channels 5, preventing problems such as casting deformation, shrinkage cavities, and porosity caused by excessive molten metal. When the molten metal completely fills the cavity 4 and cools and solidifies, the formed car seat pelvis casting can be obtained. The whole process is efficient and stable, and can produce high-quality and high-precision car seat pelvis castings.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
