Description

Technical Field

[0001] The present invention relates to the field of die-casting technology, and in particular to die-casting equipment for manufacturing aluminum alloy parts. Background Art

[0002] When manufacturing aluminum alloy parts, aluminum alloy has a relatively low melting point and good fluidity, which makes it suitable for high-pressure forming process. Die-casting equipment can provide high pressure to make the aluminum alloy liquid quickly fill the mold cavity, and can produce aluminum alloy parts with complex shapes and fine structures. Therefore, in order to meet the complex design, efficient production and high quality requirements of products, die-casting equipment is needed. For example, the patent with application number: CN202411886216.2 discloses an aluminum alloy die-casting mold with multi-cavity independent temperature control function, which can exchange heat in the mold to achieve a rapid cooling effect on the mold, thereby increasing the aluminum alloy forming speed, avoiding scalding of workers when removing the mold, and avoiding the slight vibration of the hydraulic cylinder, which makes the connection between the upper mold and the lower mold no longer tight.

[0003] However, during the operation of existing die-casting equipment for manufacturing aluminum alloy parts, for example, the die-casting mold used for product molding is usually installed at a designated position of the die-casting equipment by means of traditional fixing methods. Since the die-casting mold generally adopts an upper and lower double-mold structure, and the installation positions of the upper and lower double-molds are different, when replacing the double-mold, the staff needs to perform at least two disassembly operations. As a result, the mold replacement process is quite cumbersome, and it is very easy to reduce the overall utilization efficiency of the die-casting equipment due to the long time spent on mold replacement. Summary of the Invention

[0004] The present invention relates to a die-casting device for manufacturing aluminum alloy parts. The die-casting fixed die and the die-casting movable die can be kept in a sliding state when the die-casting fixed die and the die-casting movable die are not in use. The die-casting fixed die and the die-casting movable die in the sliding state are extremely easy to disassemble, and no excessive time is spent on disassembling the die-casting fixed die and the die-casting movable die, and the utilization efficiency of the die-casting device is not reduced due to the trivial mold changing steps.

During the lowering process, the conversion slide 19 will slide from the inside of the guide chute 3 into the inside of the guide chute 2. At this time, the conversion slide 19 will use the characteristics of the inclined structure of the guide chute 3 to move the limit plate 18 inwardly, so that the limit plate 18 is inserted into the inside of the limit slot 23 by moving inward, and the die-casting movable mold 22 is fixed in advance before die-casting to ensure the stability of the die-casting movable mold 22 during use.

[0022] The second embodiment, on the basis of the first embodiment, the guide inclined groove 3 is an inclined structure; the lowest end of the guide inclined groove 3 is connected to the top of the guide slide groove 2; two docking posts 6 are symmetrically arranged on the inner rear side of the fixed base 5; the docking post 6 is a cylindrical structure; a docking socket is provided on the rear side of the die-casting fixed mold 11; the docking post 6 is inserted into the docking socket of the die-casting fixed mold 11; the inner rear side of the limiting slide 8 is an inclined structure; the limiting slide 8 is also slidably installed on the fixed seat 4 and the support body 1 at the same time; the limiting slide 8 is an L-shaped structure; one end of the spring A9 is embedded in the inner side of the limiting slide 8; the other end of the spring A9 is embedded in the inner side of the support body 1; the inner top end of the force-bearing push block 10 is an inclined structure; a guide transverse groove is provided on the inner side of the sliding seat 13; a connector 14 is fixedly installed on the outer side of the sliding seat 13; the output end of the die-casting push cylinder 12 is fixedly connected to the connector 14 by a bolt; the bottom end of the push plug 16 is inclined The inner side of the limiting plug plate 18 is fixedly installed with an embedded slide plate 20, which can keep the die-casting fixed mold 11 and the die-casting movable mold 22 in a sliding state when the die-casting fixed mold 11 and the die-casting movable mold 22 are not in use. The die-casting fixed mold 11 and the die-casting movable mold 22 in the sliding state are very easy to disassemble, and it will not take too long to disassemble the die-casting fixed mold 11 and the die-casting movable mold 22, and it will not reduce the efficiency of the die-casting equipment due to the trivial steps of changing the mold. After the seat 15 drops to a certain position, the pushing insert 16 at the bottom end of the sliding base 15 will slide into the interior of the mounting slide groove 7. At this time, the inclined surface structure at the bottom end of the pushing insert 16 will push the inclined surface structure of the force-bearing push block 10. After the inclined surface of the force-bearing push block 10 is pushed, it will move the limiting slide plate 8 inward, so that the limiting slide plate 8 will be blocked by the inward movement on the front side of the die-casting fixed mold 11. Similarly, the die-casting fixed mold 11 is fixed in advance before die-casting to ensure the stability of the die-casting fixed mold 11 during use.

[0023] Example 3, on the basis of Example 2, the embedded slide 20 is further slidably mounted inside the contraction chute 17; one end of the spring B21 is embedded and mounted on the inner side of the embedded slide 20; the other end of the spring B21 is embedded and mounted on the inner side of the contraction chute 17; the conversion slide 19 is a cylindrical structure; the conversion slide 19 is also slidably mounted in the guide transverse groove of the sliding seat 13; the outer end of the conversion slide 19 is also slidably mounted in the guide groove structure composed of the guide chute 2 and the guide inclined groove 3; when the die-casting push cylinder 12 with the connector 14, the sliding seat 13, the sliding base 15 and the die-casting movable mold 22 descend, the conversion slide 19 will slide from the inside of the guide chute 3 into the inside of the guide chute 2; when the conversion slide 19 enters the guide chute 2 from the guide chute 3, the conversion slide 19 will move inward with the limit plate 18; after the limit plate 18 moves inward, it will be inserted into the inside of the limit slot 23; after the sliding base 15 descends, the pushing insert 16 at the bottom end of the sliding base 15 will slide into the inside of the installation chute 7; after the bottom end of the pushing insert 16 slides into the inside of the installation chute 7, the inclined surface structure of the pushing insert 16 will push the inclined surface structure of the force-bearing push block 10; after the inclined surface of the force-bearing push block 10 is pushed, it will move inward with the limiting slide plate 8; After the limiting slide plate 8 moves inward, it will abut against the front side of the die-casting fixed mold 11. When the die-casting fixed mold 11 is ready for use, the die-casting equipment adopts a combination of abutment and insertion to achieve its positioning. When the die-casting movable mold 22 is ready for use, it adopts an insertion method to achieve its positioning. Different positioning methods are suitable for the fixed and movable molds, which is convenient for the disassembly of the double molds, and the double molds can be automatically positioned before die-casting, so that the die-casting equipment can ensure that the mold is easy to disassemble, but will not affect its own stability due to the portable disassembly of the mold. After the workpiece is formed, the die-casting push cylinder 12 is restored to restore the sliding base 15 with the die-casting movable mold 22. When the die-casting movable die 11 is disassembled, the die-casting movable die 11 is disassembled, and the die-casting movable die 11 is disassembled. When the die-casting movable die 11 is disassembled, the die-casting movable die 11 is disassembled, and the die-casting movable die 11 is disassembled. When the die-casting movable die 11 is disassembled, the die-casting movable die 11 is disassembled, and the die-casting movable die 11 is disassembled. When the die-casting movable die 11 is disassembled, the die-casting movable die 11 is disassembled, and the die-casting movable die 11 is disassembled. When the die-casting movable die 11 is disassembled, the die-casting movable die 11 is disassembled, and the die-casting movable die 22 is disassembled and the die-casting movable die 22 is disassembled. The die-casting push cylinder 12 is started.

[0024] The working principle of this embodiment is as follows: when in use, the die-casting push cylinder 12 is started. Under the drive of the push cylinder, the connecting head 14, the sliding seat 13, the sliding base 15 and the die-casting movable mold 22 are synchronously lowered. During the lowering process, the conversion slide 19 will slide from the inside of the guide inclined groove 3 into the inside of the guide slide groove 2. At this time, with the help of the inclined structural characteristics of the guide inclined groove 3, the conversion slide 19 drives the limit plug 18 to move inward until the limit plug 18 is inserted into the inside of the limit slot 23, thereby completing the fixation of the die-casting movable mold 22 before the die-casting operation begins, ensuring its stability during use. When the sliding base 15 drops to a specific position, the pushing insert 16 at its bottom end will slide into the inside of the mounting slide groove 7, and the inclined surface structure of the bottom end of the pushing insert 16 and the inclined surface structure of the force-bearing push block 10 push each other. After the force is applied, the force-bearing push block 10 drives the limit slide plate 8 to move inward, thereby causing the limit slide plate 8 to resist the front side of the die-casting fixed mold 11, similarly realizing the fixation before die-casting. After the die casting fixed mold 11 is fixed in advance, its use stability is guaranteed. After the die casting fixed mold 11 and the die casting movable mold 22 are connected, the aluminum alloy liquid is injected into the mold cavity through the injection port on the die casting movable mold 22, and then the workpiece is formed. After the workpiece is formed, the die casting push cylinder 12 is operated to recover, and the sliding base 15 drives the die casting movable mold 22 to rise. During the rising process, the pushing insert 16 no longer applies a pushing force to the inclined surface of the force-bearing push block 10, and the limiting slide plate 8 is reset under the action of the spring A9, releasing the resistance limit of the die casting fixed mold 11, which is convenient for subsequent disassembly of the die casting fixed mold 11. When the die casting push cylinder 12 drives the sliding base 15 to rise to a certain position, the conversion slide post 19 slides from the guide slide groove 2 into the guide inclined groove 3. With the help of the inclined structure of the guide inclined groove 3, the conversion slide post 19 drives the limiting insert plate 18 to move outward, so that its inner end is disengaged from the inner limit slot 23. At this time, the die casting movable mold 22 resumes its sliding state, which is convenient for its disassembly.
