Description

Technical Field

[0001] The invention relates to the technical field of die-casting equipment, and in particular to a new die-casting machine for processing precision structural parts. Background Art

[0002] There are many types of existing structural die-casting equipment, which are widely used in the automotive, electronics, home appliance and other industries. Among them, the common ones are hydraulic die-casting machines, pneumatic die-casting machines and vacuum die-casting machines. The hydraulic die-casting machine uses hydraulic oil as the power source and has high pressure, which is suitable for the die-casting of large and complex structural parts; the pneumatic die-casting machine uses compressed air as the power source and has moderate pressure, which is suitable for the die-casting of small and medium-sized structural parts; the vacuum die-casting machine uses a vacuum environment during the die-casting process, which can reduce defects such as pores and shrinkage and improve product quality. In addition, there are new equipment such as servo die-casting machines and robot die-casting machines. They have the characteristics of high degree of automation, energy saving and environmental protection. These equipment are constantly optimized in terms of structure, control system, hydraulic system, cooling system, etc. to meet the needs of different industries and customers. In the field of structural die-casting equipment, technology continues to advance, and the types and functions of equipment are also richer. The hydraulic die-casting machine is suitable for its powerful pressure output. It is used to manufacture large-size structural parts such as automobile engine covers and bumpers. Pneumatic die-casting machines are often used to produce small metal parts for home appliances and electronic products because of their easy operation and low cost. Vacuum die-casting machines extract air during the die-casting process to improve the fluidity and filling capacity of the molten metal, reduce bubbles and defects, and are particularly suitable for the production of precision parts, improving production efficiency and product quality. They are suitable for multi-variety and small-batch production models. In addition, some high-end equipment is also equipped with advanced detection systems that can monitor product quality in real time during the production process to ensure that each product meets strict industrial standards. With the development of intelligence and informatization, structural die-casting equipment is also gradually developing towards intelligence. By integrating sensors, actuators, control systems, etc., the automation and intelligent management of the die-casting process are realized, which improves production efficiency and product quality, while also reducing energy consumption and maintenance costs.

[0003] When the existing mechanical seal is installed and used, firstly, the adhesion between the die casting and the mold makes demoulding difficult, which may cause deformation or damage to the product. Under the conditions of high temperature and high pressure, the interaction between the molten metal and the mold material will enhance this adhesion, which increases the demand for demoulding force and increases the burden on the equipment. Secondly, defects on the mold surface, such as wear, scratches or corrosion, will aggravate the adhesion between the molten metal and the mold, making demoulding more difficult. This not only affects the surface quality of the product, but may also cause internal stress concentration of the product due to incomplete demoulding, affecting its mechanical properties. In addition, the demoulding process may also encounter problems due to improper mold design. The unreasonable demoulding angle is insufficient, the mold cooling is uneven, and other problems will cause the product to be easily scratched, deformed or even broken during demoulding. At the same time, improper selection of release agent or uneven spraying will also affect the demoulding effect and may even cause product surface quality problems. Finally, with the increase in production batches, mold wear and fatigue problems are becoming increasingly prominent, which not only reduces the service life of the mold, but also may require frequent replacement due to poor mold condition, affecting production efficiency and cost control, which has brought certain adverse effects on people's use process. In order to solve the shortcomings of the existing technology, we propose a new die-casting machine for processing precision structural parts. Summary of the invention

[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the coordinated movement of each component is precisely controlled by the first servo motor to achieve precise positioning and movement of the upper mold and the lower mold, ensuring high closing accuracy of the mold during the die-casting process, thereby effectively reducing the generation of defects such as flash and burrs, and improving the dimensional accuracy and surface quality of the product.

In the present invention, the material discharge structure can realize the automatic demoulding operation, greatly improves the production efficiency, reduces the manual intervention, and reduces the labor intensity. Through the coordinated transmission of various components, the demoulding process is ensured to be smooth and accurate, and damage to the product is avoided. The cooperation of the first ratchet bar and the second ratchet bar, as well as the interaction between the push frame and the torsion spring block, can effectively control the timing and strength of demoulding, so that the product can be smoothly separated from the mold.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 - Figure 4 As shown, in this new die-casting machine for processing precision structural parts, first, the first servo motor 21 on one side of the base 1 is started, and then the output shaft end of the first servo motor 21 drives the detachably installed first rotating rod 212 to rotate, and then the first rotating rod 212 drives the detachably installed first bevel gears 22 on the outer walls on both sides to rotate, and then when the first bevel gear 22 rotates, the first bevel rack 23 meshing with the first bevel gear 22 is driven to slide in the limiting groove 28 provided on the upper surface of the base 1, thereby driving the detachably installed upper mold 211 to move, and at the same time, when the first rotating rod 212 rotates, the first cylindrical detachably installed in the middle is driven by the first rotating rod 212. The gear 24 rotates, and then because the first cylindrical gear 24 and the second cylindrical gear 25 are meshed with each other, the second cylindrical gear 25 is driven to rotate in the middle of the mounting frame 214 through the rotation of the first cylindrical gear 24, and then because the second cylindrical gear 25 is meshed with the sliding rack 26, the sliding rack 26 slides in the sliding groove 29, and then when the first movable frame 213 rotatably mounted at one end of the sliding rack 26 slides in the groove 210, and the middle part thereof is rotatably mounted with the base 1, the lower mold 27 rotatably mounted at one end of the first movable frame 213 is driven to move, and the lower mold 27 is within the motion trajectory of the upper mold 211. Through the coordinated movement of various components, precise positioning die-casting work is achieved.

[0035] Embodiment 2, as Figure 1 - Figure 7As shown, in the new die-casting machine, when the first rotating rod 212 rotates, the synchronous groove 31 on the outer wall of the first cylindrical gear 24 drives the synchronous wheel 32 to rotate through the transmission belt, so that the second rotating rod 33 rotates, and then when the second rotating rod 33 rotates, the first limit turntable 34 and the second limit turntable 35 at both ends are driven to rotate synchronously, and the second movable frame 37 slidably installed in the first limit turntable 34 moves accordingly, driving the first sliding frame 38 to slide, and the second sliding frame 39 slides in the trapezoidal groove of the first sliding frame 38 and moves along the limit long rod 310. At the same time, the connecting frame 311 slides in the rectangular groove of the base 1, driving the two bevel gears 312 to move. When the die-casting is completed, the first ratchet bars 315 on both sides of the lower mold 27 move with the lower mold 27 and move with the base 1 The second ratchet bar 316 on the upper part cooperates so that after the lower mold 27 moves to the lower part of the upper mold 211, the positioning bevel groove 317 in the lower mold 27 engages with the torsion spring block 319 to limit the lower mold 27. Then, when the lower mold 27 retreats, the torsion spring block 319 contacts with the pushing frame 318, so that the pushing frame 318 slides in the positioning bevel groove 317 and interacts with the torsion spring block 319 to push up the die-cast structure. Then, when the structure is pushed up, when the first ratchet bar 315 and the second ratchet bar 316 move to the motion track of the bevel gear 312, the bevel gear 312 rotates, driving the rotating block 313 to rotate, so that the electric telescopic clamp 314 works to clamp the structure, so that the structure is separated from the lower mold 27 in the subsequent movement of the lower mold 27, thereby realizing the demoulding operation.

[0036] Embodiment three, as Figure 1 - Fig. 9 As shown, in the novel die-casting machine, the two second servo motors 41 on the surface of the base 1 are started, and the output shaft ends thereof drive the detachably mounted first transmission wheel 42 to rotate. On the one hand, the first transmission wheel 42 drives the detachably mounted peristaltic pump 43 to work, so that the material is discharged through the discharge pipe 44; on the other hand, the first driven wheel 45 is driven to rotate through the transmission belt, so that the third rotating rod 46 rotates, and the detachably mounted second bevel gear 47 is driven to rotate, and the cleaning rollers 48 on both sides of the second bevel gear 47 rotate accordingly, and slide in the 410 opened on both sides of the lower mold 27 to clean the lower mold 27. Since the two second servo motors 41, related components and assemblies are distributed in a mirror image manner with the first movable frame 213 and rotate in opposite directions, the cleaning work after die-casting can be completed comprehensively and efficiently.

[0037] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
