Description

Technical Field

[0001] This application relates to the field of die casting technology, and more specifically, to a die casting mold for integrally molding a foot pedal assembly. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal within a mold cavity. The mold is typically made of a high-strength alloy, and the process is somewhat similar to injection molding. Most die-cast parts are iron-free, containing elements such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine is required.

[0003] During die casting, the mold without preheating is repeatedly subjected to rapid cooling and heating, causing deformation of the forming surface and its interior. This mutual attraction results in repeated cycles of thermal stress, leading to damage to the microstructure and loss of toughness. This triggers the appearance of microcracks, which continue to expand. Once the cracks enlarge, molten metal is squeezed in, and the repeated mechanical stress further accelerates the expansion of the cracks.

[0004] To address the aforementioned issues, this application provides a die-casting mold for integrally molding a foot pedal assembly. Summary of the Invention

[0005] The die-casting mold for integral molding of a foot pedal component provided in this application adopts the following technical solution: A die-casting mold for an integrally formed foot pedal assembly includes a mounting base, a mounting frame on the top of the mounting base, corner fixing clips at the four corners of the top of the mounting frame, a crossbar running through the long side of the mounting frame, a groove at one end of the top of the crossbar, a discharge port running through the top of the mounting base near the groove, an ejection mechanism at the opposite end of the mounting frame near the groove, a moving mold mechanism at the opposite end of the ejection mechanism away from the groove, a die-casting mechanism support frame at the top of the mounting base away from the discharge port, the die-casting mechanism support frame being located between the opposite mounting frames, a die-casting mechanism mounting frame at the top of the mounting frame away from the discharge port, a die-casting mechanism between the die-casting mechanism support frame and the die-casting mechanism mounting frame, and a fixed mold mechanism at the end of the die-casting mechanism near the moving mold mechanism.

[0009] Furthermore, the rollers in the sliding parts all slide in the sliding grooves. The first sealing groove is located inside the insertion tube. The shape of the first splicing injection groove is "丰" (Chinese character). The shape of the让位槽 is the same as that of the limiting block at one end of the ejection sub-rod close to the moving die mechanism. The shape of the first anti-overflow groove is the shape composed of the first die groove and the first splicing injection groove.

[0010] Furthermore, the fixed die mechanism includes a fixed die body. Fixed parts are provided on the adjacent sides of the fixed die body close to the moving die mechanism. Insertion grooves are evenly distributed on the periphery of one side of the fixed die body close to the moving die mechanism, and the insertion grooves and the insertion tubes are aligned with each other. A second sealing groove is provided on one side of the fixed die body close to the moving die mechanism, and the second sealing groove is located inside the insertion groove.

[0013] In summary, this application includes the following beneficial technical effects: The insertion tube of the moving mold mechanism and the insertion slot of the fixed mold mechanism are aligned and inserted into each other, playing a preliminary positioning and connection role during mold closing. This ensures that the moving mold and the fixed mold maintain a precise relative position during the die casting process, effectively preventing displacement and providing a basic guarantee for high-quality die casting. This greatly improves the dimensional accuracy and consistency of the molded parts. The first sealing groove of the moving mold body and the second sealing groove of the fixed mold body cooperate with each other to form a tight sealing space. Combined with the surrounding design of the first and second anti-overflow grooves, this effectively prevents the leakage of metal materials during the die casting process, avoiding material waste and mold damage. At the same time, it ensures stable pressure in the mold cavity, which is conducive to the full filling of the mold by the metal material, improving the quality of the molded parts. The die casting hydraulic press of the die casting mechanism drives the die casting head to slide and press down in the inner sleeve through the die casting hydraulic rod, applying high pressure to the metal material, so that it quickly fills the mold cavity and is formed under high pressure, improving the die casting efficiency. Meanwhile, the flow distribution valve plate and pressure valve plate on the flow divider pipe can precisely adjust the flow distribution and pressure of the metal material on different flow paths according to the die-casting process requirements, achieving precise control of the die-casting process and ensuring stable quality of the molded parts. The outer and inner sleeves of the injection pipe are designed with a gap to preheat or insulate the injected metal material, ensuring good fluidity of the metal material when injected into the mold, which is beneficial to improving die-casting quality. The overflow groove on the inner sleeve can promptly discharge excess material when the pressure of the metal material in the inner sleeve is too high or abnormal conditions occur, playing a role in protecting the equipment and ensuring the stability of the die-casting process.

The pressure valve plate 911 is provided with a mechanical seal partition 913 on its top, and a torsion spring 914 is provided on its top, with the torsion spring 914 located above the mechanical seal partition 913. Linkage valve plates 915 are evenly distributed on the linkage rod 912. A torsion spring sleeve 916 is provided in the middle section of the outer wall of the linkage rod 912. A connecting rectangular rod 917 is provided on the side of the outer wall of the torsion spring sleeve 916 near the diversion pipe 909. The injection duct 908 extends through the injection pipe 907 into the inner sleeve 905, and the injection pipe 907 is interconnected with the inner sleeve 905 through the injection duct 908. The linkage valve plates 915 are all located inside the end of the diversion pipe 909. The die-casting head 903 slides on the inner wall of the inner sleeve 905, and the die-casting mechanism support frame 8 is in operation. An injection pipe 907 is installed at the top, which is the main channel for metal material to enter the mold cavity. An outer sleeve 904 is installed at the top of the outer wall of the injection pipe 907, away from the moving mold mechanism 6. The outer sleeve 904 and the injection pipe 907 together form a relatively independent space. An inner sleeve 905 is installed opposite the inner wall of the outer sleeve 904, forming a certain gap between them.

The shunt valve plate 910 can adjust the flow distribution of the metal materials on different shunt paths according to the requirements of the die casting process, realizing precise control of the die casting process.

[0023] Working principle: The moving die mechanism 6 slides in the chute 12 through the rollers in the sliding member 602, making the moving die body 601 approach the fixed die mechanism 7. The insertion pipe 603 is aligned and inserted into the insertion groove 703 to achieve preliminary positioning and connection. At the same time, the first sealing groove 604 and the second sealing groove 704 cooperate to form a sealed space to prevent material overflow during die casting. The die casting hydraulic press 901 of the die casting mechanism 9 does not work. The metal materials enter the inner sleeve 905 through the injection duct 908 of the injection pipe 907. When the materials in the inner sleeve 905 reach a certain pressure, they are evenly distributed into the second mold groove 706 of the fixed die mechanism 7 and the first mold groove 606 of the moving die mechanism 6 through the shunt pipe 909, controlled by the shunt valve plate 910, the pressure valve plate 911, etc. The first splicing injection groove 607 and the second splicing injection groove 707 help the materials to fully flow and fuse in the mold. The "丰"-shaped first splicing injection groove 607 and the corresponding structure can better evenly inject the materials to form complex parts. The first anti-overflow groove 605 and the second anti-overflow groove 705 prevent the materials from overflowing the mold groove. The die casting hydraulic press 901 is started. The die casting hydraulic rod 902 drives the die casting head 903 to slide and press down on the inner wall of the inner sleeve 905, applying high pressure to the materials in the inner sleeve 905, enabling them to quickly fill the mold cavity and form under high pressure, forming the shape of the pedal assembly that meets the design requirements. After die casting, the moving die mechanism 6 moves away from the fixed die mechanism 7 along the chute 12 under the action of the driving device to achieve mold opening. The ejecting mechanism 5 works. The hydraulic pump 502 drives the hydraulic rod 503 and the ejecting main rod 504. The ejecting sub-rod 506 ejects the formed pedal assembly from the first mold groove 606 of the moving die mechanism 6. The pedal assembly falls through the discharge port 4 to complete part taking.

[0024] The above are all preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
