Description

Technical Field

[0001] In the field of die casting molds, this invention specifically relates to a die casting mold for metal products. Background Technology

[0002] In the manufacturing process of metal products, die-casting molds are one of the key pieces of equipment for achieving high-precision and high-efficiency production. Traditional die-casting molds for metal products typically consist of an upper mold and a lower mold. The upper mold carries the upper mold cavity, while the lower mold includes the lower mold cavity and various forming slides that work together to form the desired shape and structure of the metal product. However, in practical applications, existing technologies have several shortcomings, especially when dealing with metal products with complex structures or requiring high-precision forming.

[0003] On the one hand, traditional molds often rely on a single forming slide design when molding metal products with side holes or special shapes. This not only limits the flexibility of the mold but also makes it difficult to guarantee the dimensional accuracy and surface quality of each part of the product. In particular, when metal products require multiple fine hole structures on the same or different sides, a single forming slide may not be able to meet the high-precision molding requirements, resulting in a decrease in product qualification rate.

[0004] On the other hand, the venting system in the mold is crucial for the die-casting process. An inadequate venting design can lead to ineffective gas removal from the cavity, resulting in defects such as porosity and shrinkage cavities during die casting, severely impacting the mechanical properties and appearance quality of the metal products. Existing molds often feature simple venting channels, lacking effective venting mechanisms for complex metal structures. Especially in large or complex cavities, single or asymmetrical venting channels struggle to ensure uniform gas discharge, further affecting the quality of the die-cast parts.

[0005] Furthermore, the control of molten metal flow during die casting is also a key factor affecting product quality. The design of the main runner must ensure that the molten metal can smoothly and evenly fill the entire cavity, while the overflow groove is used to regulate and control the flow of molten metal, avoiding local overpressure or insufficient filling. However, the layout of the main runner and overflow groove in existing molds is often not optimized enough, making it difficult to adapt to the molding requirements of different metal products, resulting in uneven molten metal flow and affecting the overall performance and consistency of the product. Utility Model Content

[0006] The purpose of this application is to provide a die-casting mold for metal products that can improve the production efficiency, dimensional accuracy and overall quality of metal products.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A die-casting mold for metal products includes an upper mold and a lower mold. The upper mold includes an upper template with an upper mold cavity. The lower mold includes a lower template, a first forming slide, and a second forming slide. The lower template has a lower mold cavity corresponding to the upper mold cavity. The first forming slide is located on one side of the lower template and is used to cooperate with the lower mold cavity to form a side hole of the metal product. The second forming slide is located on the other side of the lower template and is used to cooperate with the lower mold cavity to form another side hole of the metal product. A main channel is provided on one side of the lower mold cavity, and multiple overflow grooves are provided on the other side of the lower mold cavity corresponding to the main channel. The multiple overflow grooves are respectively connected to a first venting groove and a second venting groove, and the first venting groove and the second venting groove are symmetrically arranged.

[0009] In one embodiment, the main channel is provided with a plurality of diversion bumps, which divide the main channel into a plurality of diversion slots.

[0010] In one embodiment, a syringe positioning groove is provided on one side of the upper template.

[0011] In one embodiment, a plurality of first forming protrusions are provided on the first forming row.

[0012] In one embodiment, a second forming protrusion is provided on the second forming row.

[0013] The beneficial effects of this application are as follows:

[0014] (1) This application design introduces a first forming slide and a second forming slide, respectively located on both sides of the lower mold plate. This dual forming slide design greatly enhances the forming capability of the mold. Whether multiple fine hole structures need to be formed on the same side or different sides of the metal product, this mold can achieve a high-precision and high-flexibility forming effect through the precise cooperation between these two forming slides and the lower mold cavity. This not only improves the product qualification rate, but also significantly improves the dimensional accuracy and surface quality of the product.

[0015] (2) This application provides multiple overflow channels, which are respectively connected to symmetrically arranged first and second venting channels. This symmetrical and multi-channel venting design ensures the effective removal of gas from the mold cavity during the die-casting process, avoiding defects such as porosity and shrinkage cavities. Especially in large or complex cavities, this venting system can ensure uniform gas discharge, thereby significantly improving the mechanical properties and appearance quality of metal products.

[0016] (3) The optimized layout of the main channel and multiple overflow channels in this application enables the molten metal to fill the entire cavity smoothly and evenly during the die casting process. The ingenious design of the overflow channels not only regulates the flow of the molten metal but also effectively avoids problems such as local overpressure or insufficient filling. This design ensures the uniformity of the properties of various parts of the metal product and improves the overall performance and consistency of the product.

[0017] The significant optimizations in molding accuracy, venting efficiency, and molten metal flow control in this mold result in a more stable and reliable die-casting process. This not only improves the production efficiency of metal products but also reduces material waste and production costs caused by product defects. Simultaneously, the optimized design lowers mold maintenance costs, further enhancing the company's economic benefits. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the structure of the lower mold cavity of a die-casting mold for metal products provided in an embodiment of this application; Detailed Implementation

[0020] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] Example 1:

[0022] like Figures 1 to 2 As shown, this embodiment provides a die-casting mold for metal products, which includes an upper mold 1 and a lower mold 2. The upper mold 1 mainly includes an upper template 11, on which an upper mold cavity 12 is provided for forming a portion of the shape of the metal product. The lower mold 2 includes a lower template 21, a first forming slide 22, and a second forming slide 23. A lower mold cavity 24 is provided on the lower template 21 corresponding to the upper mold cavity 12, so as to cooperate with the upper mold cavity 12 to complete the forming of the main body of the metal product.

[0023] The first forming slide 22 is located on one side of the lower mold plate 21, and its purpose is to cooperate with the lower mold cavity 24 to form a side hole on the metal product. Similarly, the second forming slide 23 is located on the other side of the lower mold plate 21, and is used to cooperate with the lower mold cavity 24 to form another side hole on the metal product. This design allows the mold to complete the forming of multiple faces and side holes of the metal product in one operation, improving production efficiency.

[0024] To optimize the flow of molten metal and venting, a main channel 25 is provided on one side of the lower mold cavity 24 to guide the molten metal into the mold. On the other side of the lower mold cavity 24 corresponding to the main channel 25, multiple overflow channels 26 are provided. These overflow channels 26 help regulate the pressure inside the mold and ensure uniform filling of the metal product. Furthermore, the multiple overflow channels 26 are connected to the outside through a first venting channel 27 and a second venting channel 28, respectively. The first venting channel 27 and the second venting channel 28 are symmetrically arranged. This layout is beneficial for effectively removing gas during the die casting process, avoiding bubble formation, and improving the quality of the metal product.

[0025] Example 2:

[0026] Based on Example 1, this example improves upon the main channel 25. For example... Figure 2 As shown, the main channel 25 is provided with multiple diversion bumps 251, which divide the main channel 25 into multiple diversion grooves. This design can distribute the flow rate of molten metal more evenly, ensuring that the filling speed of the metal is consistent in each part, and further improving the forming quality and dimensional accuracy of the metal products.

[0027] Example 3:

[0028] Based on Embodiment 1 or Embodiment 2, in order to facilitate accurate placement of the syringe during the production process, this embodiment adds a syringe positioning groove 13 to one side of the upper template 11 (e.g., Figure 1 (As shown). The positioning groove 13 can be precisely designed according to the shape of the syringe to ensure that the syringe is stable and does not shake during the die-casting process, thereby improving the accuracy and safety of injection.

[0029] Example 4:

[0030] like Figure 1 As shown, in order to improve production efficiency and meet the simultaneous forming requirements of multiple through holes on metal products, this embodiment provides multiple first forming protrusions 221 on the first forming slide 22. These first forming protrusions 221 can be flexibly arranged according to the design requirements of the metal products, realizing the forming of multiple through holes at one time, reducing subsequent processing steps, and improving overall production efficiency.

[0031] Example 5:

[0032] Continue to refer to Figure 1 In this embodiment, a second forming protrusion 231 is also provided on the second forming slide 23, specifically for forming the other side hole of the metal product. This design not only enhances the versatility and flexibility of the mold, but also ensures the dimensional accuracy and surface quality of the side hole of the metal product by precisely controlling the shape and position of the second forming protrusion 231, thus meeting higher product requirements.
