Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a baffle structure for a die casting mold. Background Technology

[0002] In die-casting molds, the baffle structure is a key functional component used to control the flow direction of molten metal, balance mold temperature, prevent flash, or assist in mold positioning.

[0003] In existing technologies, die-casting molds are crucial process equipment in die-casting production, and their performance directly affects the smooth progress of production and the quality of castings. During die-casting, high-temperature molten metal is rapidly filled into the mold cavity under high pressure. After the mold closes, gaps remain at the parting surface. Due to the fluidity of the high-temperature molten metal, under high pressure, this metal can easily overflow from the parting surface gaps, resulting in defects such as flash and burrs. These defects not only affect the appearance quality of the castings but also increase subsequent processing costs and reduce production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a retaining bar structure for a die-casting mold to address the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A baffle structure for a die-casting mold, comprising:

[0007] The die-casting mold body has two handles installed on one side and two fixing bolts installed on the other side. A baffle assembly is provided in the middle of the die-casting mold body.

[0008] A positioning component is disposed on top of the stop bar assembly to fix the position of the stop bar assembly.

[0009] As a preferred embodiment of the baffle structure of the die-casting mold provided by this utility model, the baffle assembly includes two baffle bodies, the inner wall of the baffle body is fitted with the outer wall of the die-casting mold body, and both ends of the baffle body are connected to a fixing plate.

[0010] In a preferred embodiment of the baffle structure of the die-casting mold provided by this utility model, a soft pad is provided between the two fixed plates on the same side. A round hole is provided in the middle of both the fixed plate and the soft pad, and a positioning hole is provided on one side of the round hole.

[0011] In a preferred embodiment of the retaining strip structure of the die-casting mold provided by this utility model, a fastening bolt is provided on one side of the fixing plate, and a locking block is connected to one side of the fastening bolt.

[0012] In a preferred embodiment of the retaining strip structure of the die-casting mold provided by this utility model, the locking block is engaged with the positioning hole, and one end of the fastening bolt passes through multiple corresponding round holes in sequence.

[0013] In a preferred embodiment of the retaining strip structure of the die-casting mold provided by this utility model, one end of the fastening bolt is connected to a threaded ring, and the outer wall of the threaded ring is uniformly connected with a plurality of anti-slip blocks.

[0014] In a preferred embodiment of the baffle structure of the die-casting mold provided by this utility model, the positioning component includes a pressure bar, the bottom end of which is fitted with the top end of the die-casting mold body.

[0015] In a preferred embodiment of the baffle structure of the die-casting mold provided by this utility model, both sides of the bottom end of the baffle are connected with irregular parts, and the irregular parts are engaged with the outer wall of the baffle body.

[0016] In a preferred embodiment of the retaining strip structure of the die-casting mold provided by this utility model, a horizontal plate is engaged with the middle of one of the irregular parts, and arc plates are connected to both ends of the horizontal plate, and the arc plates are engaged with the corresponding pull handle.

[0017] As a preferred embodiment of the baffle structure of the die-casting mold provided by this utility model, another irregular part is provided with a baffle at the bottom, the top of the baffle is attached to the bottom of the corresponding fixing bolt, and a gasket is fixedly connected to the middle of the top of the baffle, the top of the gasket is connected to the bottom of the corresponding irregular part.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a baffle structure for a die-casting mold. The baffle body fits snugly against the mold's closing gap, forming a reliable physical barrier. This significantly reduces the risk of molten metal overflowing from the parting surface under high pressure, minimizing defects such as flash and burrs, improving the surface quality and dimensional accuracy of the casting, and lowering subsequent processing costs. It is particularly suitable for the production of precision die-cast parts with strict surface finish requirements. Furthermore, the engaging design of the fastening bolts and positioning holes, combined with the anti-slip structure of the threaded ring, ensures stable connection of the baffle assembly under high pressure conditions, preventing loosening due to vibration or thermal expansion. Simultaneously, the modular design facilitates quick disassembly and replacement. When the baffle body wears down due to long-term use, individual components can be replaced without disassembling the entire mold, significantly reducing maintenance downtime and improving production efficiency.

[0020] This utility model provides a stop bar structure for a die-casting mold. Through the interlocking design of the arc-shaped plate with the handle, and the baffle with the fixing bolt, it directly utilizes the existing mold structure to achieve precise positioning of the stop bar assembly, eliminating the need for additional independent fixing devices. This design not only simplifies the mold structure and reduces material consumption but also lowers the complexity of mold design and processing. It is particularly suitable for cost-sensitive mass production scenarios. Furthermore, the positioning component uses a slightly deformable material, allowing it to flexibly adapt to different specifications of handles and fixing bolt positional deviations. Simultaneously, the interlocking of the irregularly shaped part with the stop bar body enhances connection stability. This adaptable design allows the same positioning component to be applied to various types of die-casting molds, reducing mold development cycles and inventory costs, and significantly improving the flexibility and responsiveness of the production line.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A baffle structure for a die-casting mold includes a die-casting mold body 1. Two handles 2 are installed on one side of the die-casting mold body 1, and two fixing bolts 3 are installed on the other side. A baffle assembly 4 is provided in the middle of the die-casting mold body 1. The baffle assembly 4 includes two baffle bodies 41, the inner wall of which is fitted against the outer wall of the die-casting mold body 1. Both ends of the baffle bodies 41 are connected to fixing plates 42. A soft pad 43 is provided between the two fixing plates 42 on the same side. A circular hole 44 is opened in the middle of both the fixing plates 42 and the soft pad 43. A positioning hole 45 is opened on one side of the circular hole 44. A fastening bolt 46 is provided on one side of the fixing plate 42, and a locking block 47 is connected to one side of the fastening bolt 46. The locking block 47 engages with the positioning hole 45, and one end of the fastening bolt 46 passes through multiple corresponding circular holes 44 in sequence. One end of the fastening bolt 46 is connected to a threaded ring 48, and the outer wall of the threaded ring 48 is uniformly connected with a plurality of anti-slip blocks 49.

[0032] It is worth mentioning that the baffle body 41 is set at the gap position after the die-casting mold body 1 is closed. Its inner wall is tightly fitted with the outer wall of the die-casting mold body 1 to cover the gap and prevent the high-temperature molten metal from overflowing. The fixing plate 42 is connected to both ends of the baffle body 41 to fix and support the baffle body 41. The soft pad 43 is set between the two fixing plates 42 on the same side to buffer and seal. The round hole 44 is opened in the middle of the fixing plate 42 and the soft pad 43 for the fastening bolt 46 to pass through. The positioning hole 45 is opened on one side of the round hole 44 and is engaged with the locking block 47 to prevent the fastening bolt 46 from rotating. One end of the fastening bolt 46 passes through multiple corresponding round holes 44 in sequence to fasten the baffle assembly 4. The locking block 47 is connected to one side of the fastening bolt 46 and is engaged with the positioning hole 45 to realize the positioning of the fastening bolt 46. The threaded ring 48 is connected to one end of the fastening bolt 46. Multiple anti-slip blocks 49 are evenly connected to the outer wall to facilitate manual rotation of the fastening bolt 46.

[0033] The baffle body 41 is positioned in the gap after the die-casting mold body 1 is closed. A fastening bolt 46 passes through the circular hole 44, and a locking block 47 is engaged inside the positioning hole 45 to prevent the fastening bolt 46 from rotating. The threaded ring 48 is manually rotated, and the anti-slip block 49 increases the friction between the finger and the threaded ring 48, making the rotation of the threaded ring 48 easier and thus securing the baffle assembly 4. The baffle assembly 4 forms a physical barrier, effectively preventing high-temperature molten metal from overflowing from the parting surface under high pressure, and avoiding defects such as flash and burrs.

[0034] The system also includes a positioning component 5, which is disposed on top of the stop bar assembly 4 to fix the position of the stop bar assembly 4. The positioning component 5 includes a pressure strip 51, the bottom end of which is fitted to the top end of the die-casting mold body 1. Both sides of the bottom end of the pressure strip 51 are connected to shaped parts 52, which are engaged with the outer wall of the stop bar body 41. One of the shaped parts 52 has a horizontal plate 53 engaged in the middle, and both ends of the horizontal plate 53 are connected to arc-shaped plates 54, which are engaged with the corresponding handle 2. The bottom of the other shaped part 52 is provided with a baffle 55, the top end of which is fitted to the bottom end of the corresponding fixing bolt 3, and a gasket 56 is fixedly connected to the middle of the top end of the baffle 55, the top end of which is connected to the bottom end of the corresponding shaped part 52.

[0035] Through the above structural design, the bottom end of the pressure strip 51 is fitted with the top end of the die-casting mold body 1 to fix the position of the baffle assembly 4. The irregular part 52 is connected to both sides of the bottom end of the pressure strip 51 and is engaged with the outer wall of the baffle body 41 to fix the pressure strip 51 to the baffle body 41. The horizontal plate 53 is engaged with the middle of one of the irregular parts 52. The arc plate 54 is connected to both ends of the horizontal plate 53 and is engaged with the corresponding pull handle 2 to further fix the baffle assembly 4. The baffle 55 is set at the bottom of the other irregular part 52, and its top end is fitted with the bottom end of the corresponding fixing bolt 3 to pull the pressure strip 51 and increase the stability of the baffle assembly 4.

[0036] Preferably, utilizing the characteristics of the handles 2 and fixing bolts 3 originally installed on both sides of the die-casting mold body 1, the irregularly shaped part 52 is engaged with the outside of the retaining strip body 41. The retaining strip body 41 is initially fixed by the arc-shaped plate 54 engaged with the outside of the handle 2, preventing it from shaking. The irregularly shaped part 52 on the other side is placed horizontally below the fixing bolt 3 via a baffle 55, pulling the pressure strip 51 and further positioning the retaining strip body 41. The positioning component 5 is made of a material that can undergo slight deformation to facilitate fixing with the handle 2 and fixing bolt 3, thereby helping to increase the stability of the retaining strip assembly 4. This structure utilizes the original components of the mold for fixing, eliminating the need for additional complex fixing devices, saving costs and improving the stability and reliability of the mold.
