Description

Technical Field

[0001] This application relates to the technical field of die casting, and in particular to a mold having a vertical overflow groove structure. Background Technology

[0002] In die casting, the slag pot not only contains molten metal and gas, but also serves as an auxiliary ejection mechanism in actual production. When ejector pins cannot be directly installed on the casting due to its complex structure, limited space, or high surface quality requirements, the slag pot is often placed in the ejection area. The ejection mechanism pushes the slag pot, thereby helping the casting to be demolded smoothly.

[0003] To achieve efficient slag removal, the slag pot is typically connected to the casting via a transverse, thin-plate gating system. This gating system is then easily separated in subsequent processes by simple tapping. However, during ejection, the connection is too weak. Although easy to remove, it is prone to breakage during ejection, causing the slag pot to detach from the casting, resulting in ejection failure or even mold jamming and production stoppage. Strengthening the connection to ensure ejection reliability, however, makes slag pot removal difficult, requiring secondary processing that can easily damage the casting. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a mold with a vertical overflow groove structure that improves the reliability of the slag bag ejection and makes the slag bag easy to remove.

[0005] The objective of this application is achieved through the following technical solution: A mold with a vertical overflow groove structure includes a mold body, which forms a cavity when the mold is closed. The mold with the vertical overflow groove structure further has at least one vertical overflow groove located within the mold body. The inner wall of the cavity is provided with a vertical overflow port, and the vertical overflow groove is connected to the cavity through the vertical overflow port; The length direction of the vertical overflow port is parallel to the ejection direction of the vertical slag bag, and an ejection through hole is provided at the bottom of the vertical overflow trough for ejection by ejector pins. The vertical overflow trough is used to form a vertical slag bag, and the vertical overflow port is used to form the connecting part of the vertical slag bag.

[0006] In one embodiment, the width of the vertical overflow port is 1mm-1.5mm.

[0007] In one embodiment, the cross-sectional area of ​​the vertical overflow channel gradually decreases from the center to both ends.

[0008] In one embodiment, the cross-sectional area of ​​the vertical overflow port gradually increases from the end connected to the cavity toward the end connected to the vertical overflow groove.

[0009] In one embodiment, the inner wall of the cavity is provided with a guide surface along the vertical overflow port.

[0010] In one embodiment, the mold with the vertical overflow groove structure also has an exhaust groove, one end of which is connected to the corresponding vertical overflow groove, and the other end of which extends to the outside of the mold with the vertical overflow groove structure.

[0011] In one embodiment, the number of vertical overflow channels is multiple.

[0012] In one embodiment, the mold with the vertical overflow groove structure also has a horizontal overflow groove, the inner wall of the cavity is provided with a horizontal overflow port, the horizontal overflow groove is connected to the cavity through the horizontal overflow port, and a through hole is provided at the bottom of the horizontal overflow groove for ejector pins to eject.

[0013] Compared with the prior art, this application has at least the following advantages: 1. The mold with the vertical overflow groove structure described above forms a vertical slag bag that connects the product through the vertical overflow groove and the vertical overflow port. Furthermore, by opening an ejection through hole at the bottom of the vertical overflow groove, the ejector pin ejects the vertical slag bag through the ejection through hole during ejection, thereby driving the product to demold and improving production stability.

[0014] 2. The vertical slag bale formed within the vertical overflow trough creates a vertical strip-shaped connection between the slag bale and the product. The length of the contact surface is parallel to the ejection direction of the slag bale, enhancing its shear resistance. Therefore, the slag bale is less prone to breakage during ejection, preventing ejection failure or mold jamming caused by the slag bale detaching from the product, thus improving the reliability of the slag bale-assisted ejection. Furthermore, the slag bale can be separated simply by lateral tapping, minimizing product damage and eliminating the need for secondary processing, thereby improving production efficiency.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 6This invention relates to a mold 10 with a vertical overflow groove structure, comprising a fixed mold body that forms a cavity 200 when the mold body is closed. The mold 10 also has at least one vertical overflow groove 300. The vertical overflow groove 300 is located within the mold body. A vertical overflow port 210 is provided on the inner wall of the cavity 200, and the vertical overflow groove 300 communicates with the cavity 200 through the vertical overflow port 210. The length direction of the vertical overflow port 210 is parallel to the ejection direction of the vertical slag bag, and an ejection through hole 310 is provided at the bottom of the vertical overflow groove 300 for ejection by ejector pins. The vertical overflow groove 300 is used to form the vertical slag bag (not shown), and the vertical overflow port 210 is used to form the connecting part of the vertical slag bag (not shown).

[0021] In this embodiment, the mold 10 with a vertical overflow channel structure forms a vertical slag bag connected to the product through the vertical overflow channel 300 and the vertical overflow port 210. An ejection through-hole 310 is provided at the bottom of the vertical overflow channel 300. During ejection, the ejector pin ejects the vertical slag bag through the ejection through-hole 310, driving the product to demold and improving production stability. Simultaneously, the vertical strip-shaped connecting part of the vertical slag bag formed within the vertical overflow port 210 has its contact surface length direction parallel to the ejection direction of the vertical slag bag, enhancing the shear resistance of the vertical slag bag. Therefore, the vertical slag bag is less prone to breakage during ejection, avoiding ejection failure or mold jamming caused by the vertical slag bag detaching from the product, thus improving the reliability of the vertical slag bag's assisted ejection. Furthermore, the vertical slag bag can be separated simply by lateral tapping, minimizing product damage and eliminating the need for secondary processing, thereby improving production efficiency.

[0022] like Figure 3 and Figure 4 As shown, in one embodiment, the width of the vertical overflow port 210 is 1mm-1.5mm. The size of the vertical overflow port 210 determines the strength of the connection of the vertical slag bag and the area of ​​the contact surface between the vertical slag bag and the product. By controlling the width of the vertical overflow port 210, it is ensured that the vertical slag bag is not easily broken during ejection, and that the vertical slag bag can be separated by tapping in subsequent processing. At the same time, the overflow port mark on the product can be reduced, avoiding slag bag residue or damage to the product, and improving post-processing efficiency. Further, in this embodiment, the width of the vertical overflow port 210 is 1.4mm.

[0023] like Figures 2 to 4 As shown, in one embodiment, the cross-sectional area of ​​the vertical overflow channel 300 gradually decreases from the center to both ends. It can be understood that the cross-sectional area of ​​the vertical overflow channel 300 is largest on the parting surface and smallest at both ends, meaning the cross-sectional area of ​​the vertical slag pack in the demolding direction decreases, which is beneficial for demolding. Simultaneously, the ejector pins are positioned at the center of the small end face to ensure uniform force on the vertical slag pack during ejection.

[0024] like Figures 2 to 4 As shown, in one embodiment, the cross-sectional area of ​​the vertical overflow port 210 gradually increases from the end connecting the cavity 200 to the end connecting the vertical overflow channel 300. It is understood that the smaller cross-sectional area at the end of the vertical overflow port 210 connecting to the cavity 200 results in a smaller cross-sectional area at the end of the vertical slag bag's connection near the product, facilitating removal by tapping during subsequent processing, preventing slag bag residue or damage to the product, and improving post-processing efficiency. Simultaneously, the larger cross-sectional area at the end of the vertical slag bag's connection near the vertical slag bag increases the strength of the vertical slag bag, making it less prone to breakage during ejection, avoiding demolding failure or jamming, and improving production stability.

[0025] like Figure 3 and Figure 4 As shown, in one embodiment, a guide surface 211 is provided on the inner wall of the cavity 200 along the vertical overflow port 210, and the two sides of the guide surface 211 are respectively connected to the inner wall of the cavity 200 and the side wall of the cavity 200. By providing the guide surface 211 along the vertical overflow port 210 inside the cavity 200, the inlet area of ​​the vertical overflow port 210 is enlarged, so that the leading edge cold material and gas from different directions of the cavity 200 can flow more smoothly into the vertical overflow groove 300.

[0026] like Figures 2 to 4 As shown, in one embodiment, the mold 10 with the vertical overflow groove structure also has a venting groove 400. One end of the venting groove 400 is connected to the corresponding vertical overflow groove 300, and the other end of the venting groove 400 extends to the outside of the mold 10 with the vertical overflow groove structure. It can be understood that the function of the venting groove 400 is to provide a discharge channel for the gas entering the vertical overflow groove 300, thereby guiding the gas to the outside of the mold 10 with the vertical overflow groove structure, preventing gas accumulation within the vertical overflow groove 300, allowing the melt to smoothly fill the mold, and ensuring product quality. Simultaneously, ensuring the smooth filling of the vertical overflow groove 300 by the melt ensures the structural integrity and sufficient strength of the vertical slag bag.

[0027] like Figure 3 and Figure 4 As shown, in one embodiment, there are multiple vertical overflow channels 300. By setting vertical overflow channels 300 at different ends or in thick areas, cold material and gas at the leading edge of the flow path are collected, eliminating local exhaust blind spots and improving product quality and production stability. Specifically, in this embodiment, the mold 10 with the vertical overflow channel structure can produce four workpieces simultaneously, and each workpiece is provided with a vertical overflow channel 300.

[0028] like Figures 2 to 4As shown, in one embodiment, the mold 10 with a vertical overflow groove structure also has a horizontal overflow groove 500. A horizontal overflow port (not shown) is provided on the inner wall of the cavity 200. The horizontal overflow groove 500 is connected to the cavity 200 through the horizontal overflow port. A through hole 510 is provided at the bottom of the horizontal overflow groove 500 for ejection by ejector pins. It can be understood that a horizontal slag bag connected to the product is formed through the horizontal overflow groove 500 and the horizontal overflow port. The horizontal slag bag is ejected by ejector pins through the through hole 510 at the bottom of the horizontal overflow groove 500 during ejection, driving the product to demold and improving production stability. Simultaneously, the horizontal overflow groove 500 is suitable for locations where the product thickness cannot accommodate a vertical overflow groove 300, improving the adaptability and production stability of the mold 10 with the vertical overflow groove structure.

[0029] Compared with the prior art, this application has at least the following advantages: 1. The mold with the vertical overflow groove structure described above forms a vertical slag bag connected to the product through the vertical overflow groove and the vertical overflow port. By opening an ejection through hole at the bottom of the vertical overflow groove, the ejector pin ejects the vertical slag bag through the ejection through hole during ejection, thereby driving the product to demold and improving production stability.

[0030] 2. The vertical slag bale formed within the vertical overflow trough creates a vertical strip-shaped connection between the slag bale and the product. The length of the contact surface is parallel to the ejection direction of the slag bale, enhancing its shear resistance. Therefore, the slag bale is less prone to breakage during ejection, preventing ejection failure or mold jamming caused by the slag bale detaching from the product, thus improving the reliability of the slag bale's assisted ejection. Furthermore, the slag bale can be separated simply by lateral tapping, minimizing product damage and eliminating the need for secondary processing, thereby improving production efficiency.

[0031] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
