Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, in particular to a die-casting device for nonferrous metals with a controllable cooling channel. Background Art

[0002] In modern industrial production, non-ferrous metals (such as aluminum alloys, magnesium alloys, and zinc alloys) are widely used in the automotive, aerospace, and electronics industries due to their excellent physical and chemical properties. Die casting, a highly efficient non-ferrous metal forming process, injects molten metal into a mold cavity under high pressure and cools and solidifies it, enabling high-precision molding of complex parts. The design and control of cooling channels and the precision of mold fit are key factors influencing the quality of die-cast parts.

[0003] In the die-casting process of non-ferrous metals with controllable cooling channels, the mold installation and positioning methods of existing die-casting molding devices are relatively crude in terms of mold fitting. Most of them are positioned manually or by simple machinery, which makes it difficult to ensure the flatness of the fitting surface when the upper and lower molds are merged. Gaps are prone to occur, causing metal liquid to leak during the die-casting process, affecting the surface quality and dimensional accuracy of the casting. In addition, the mold positioning structure of traditional devices has poor versatility and is difficult to quickly adapt to molds of different sizes. When replacing the mold, a lot of time is required for debugging and calibration, which greatly reduces production efficiency. At the same time, there is a lack of effective buffering measures during the mold merging process. The impact of the collision will not only damage the mold, but will also further aggravate the unevenness of the fitting surface, shorten the service life of the mold, and increase production costs.

[0004] Even though some existing devices utilize centering mechanisms to assist mold positioning, they often suffer from insufficient centering accuracy and an inability to adapt to changes in mold size. For example, traditional centering mechanisms are often designed with fixed specifications. Changes to mold size require replacing the entire centering component, which is cumbersome and costly. Furthermore, existing cushioning structures typically employ only a single buffer element located locally within the mold, making it difficult to achieve uniform cushioning, effectively eliminating impact forces during the merging process, and failing to enhance the sealing of the mold's mating surfaces through elastic deformation.

[0005] Therefore, a die-casting device for nonferrous metals with a controllable cooling channel is proposed to solve the above problems. Summary of the Invention

[0013] Preferably, the elastic buffer mechanism also includes a positioning body, which is fixedly connected to the end of the cover tube away from the electromagnetic column.

An auxiliary spring body is provided on the outer ring of the sleeve group, and one end of the auxiliary spring body is fixedly connected to the positioning body. A buffer pad is fixedly connected to the end of the sleeve group away from the positioning body.

[0014] Preferably, a cavity is provided in the body of the device, and four connecting columns are provided on the four-way auxiliary block, which are fixedly intercepted on the rotating block and distributed in a rectangular shape.

[0017] Compared with the prior art, the present invention provides a die-casting device for nonferrous metals with a controllable cooling channel, which has the following beneficial effects:

[0018] 1. By setting the positioning locking guide mechanism, under the telescopic control of the electric telescopic rod, the position of the inner slider and the outer slider is changed to realize the positioning and guiding function of the die-casting mold. The die-casting mold is fine-tuned in four directions. The position of the upper and lower molds in the die-casting mold can be adjusted more accurately to ensure that the upper and lower molds have a high verticality when merged, thereby improving the centering accuracy, helping to reduce the misalignment and deviation between the molds, and improving the dimensional accuracy and quality stability of the die-casting parts. The improvement of the verticality of the merger enables the metal liquid to evenly fill the mold cavity during the die-casting process, reducing defects such as flash and burrs caused by uneven mold gaps, and helping to improve the surface quality and internal quality of the die-casting parts.

[0019] 2. Through the setting of the elastic buffer mechanism, when the positioning body is fitted with the surface of the die-casting mold, there is a buffer space between it and the centering slide through the use of the electromagnetic column, the cover tube and the return spring body, so that it can be adapted to die-casting molds of different sizes and specifications, and is not limited to die-casting molds of a specific size. It shortens the production preparation time, improves the flexibility and response speed of production, can quickly verify the die-casting effects of molds of different sizes, timely adjust product design and mold structure, improve R&D efficiency, and reduce production downtime caused by equipment replacement or mold incompatibility.

[0020] 3. By setting the buffer pad, the impact force generated when the upper and lower molds in the die-casting mold are merged can be effectively absorbed, the rigid collision between the die-casting molds can be reduced, and the wear, deformation and cracks on the merged surface of the die-casting molds can be reduced, thereby extending the service life and reducing the maintenance and replacement costs. Furthermore, the elastic deformation of the buffer pad can adaptively fill the tiny gaps on the merged surface of the die-casting mold, preventing the metal liquid from overflowing from these gaps during the die-casting process, avoiding the generation of flash, and improving the molding quality and appearance quality of the casting.

[0040] Further examples: Please refer to Figures 7 and 8 As shown:

[0041] The elastic buffer mechanism 3 is used to perform positioning adaptation functions according to different specifications of the die-casting mold 23 and improve the sealing when closed. The elastic buffer mechanism 3 includes an electromagnetic column 31, which has a built-in drive source. The electromagnetic column 31 is fixedly connected to the center of the surface adjacent to the centering slide 210. The outer ring of the electromagnetic column 31 is slidably sleeved with a cover tube 32. A return spring body 34 is fixedly connected to the cover tube 32. The end of the return spring body 34 away from the cover tube 32 is fixedly connected to the electromagnetic column 31. A magnetorheological fluid 33 is installed in the cover tube 32. The magnetorheological fluid 33 is mainly used to solidify when energized to position the positioning body 35.

[0042] The elastic buffer mechanism 3 also includes a positioning body 35, and pressure sensors are provided on the surfaces of the four positioning bodies 35. The positioning body 35 is fixedly connected to the end of the cover tube 32 away from the electromagnetic column 31. The middle part of the side of the positioning body 35 away from the cover tube 32 is provided with an inner groove 36, and the top center of the inner groove 36 is fixedly connected to a sleeve group 37. The sleeve group 37 and the auxiliary spring body 38 are used in conjunction with the auxiliary buffer pad 39 to be clamped into the closed gap between the upper and lower molds of the die-casting mold 23. The outer ring of the sleeve group 37 is provided with an auxiliary spring body 38, and one end of the auxiliary spring body 38 is fixedly connected to the positioning body 35. The end of the sleeve group 37 away from the positioning body 35 is fixedly connected to the buffer pad 39. The buffer pad 39 is mainly used to adaptively fill the small gap and improve the closing tightness during the merging process of the upper and lower molds of the die-casting mold 23. The buffer pad 39 is composed of a circular slider sliding in the inner groove 36 and a horizontal buffer strip made of polyurethane. Four buffer pads 39 are provided, and the length of the buffer pad 39 corresponds to the length and width of the upper and lower molds of the die-casting mold 23.

[0043] Everything in the above example works as follows:

[0044] In the initial state: the die-casting mold 23 with set specifications is placed in the base 1, the electric telescopic rod 24 is in the extended state, the positioning body 35 is not in contact with the die-casting mold 23 on all four sides, and the upper mold of the die-casting mold 23 is not spliced ​​and merged with the lower mold.

[0045] The following is a working process of the positioning locking guide mechanism 2 for causing the upper and lower molds of the die-casting mold 23 to be flatly docked and positioned after alignment during the die-casting process of the upper and lower molds of the die-casting mold 23 for non-ferrous metal die-casting:

[0046] During use, when the upper and lower molds in the die-casting mold 23 are being merged, the electric telescopic rod 24 is controlled by an external controller to start and retract inward. In the process of retraction, the output end of the electric telescopic rod 24 is fixedly connected to one of the inner sliders 28. Therefore, the retraction movement of the electric telescopic rod 24 drives the inner slider 28 to move toward the electric telescopic rod 24. At the same time, with the assistance of the slide chute body 26, the inner slider 28 moves in a straight line toward the center of the four-way auxiliary block 25. Since one end of the folding rotating rod 27 is rotatably connected to the inner slider 28, during the movement of the inner slider 28, the connection between the inner slider 28 and the folding rotating rod 27 is used as the axis to prompt the folding rotating rod 27 to deflect in the opposite direction. This reverse deflection process makes the folding The end of the rotating rod 27 away from the inner slider 28 generates a thrust synchronously, prompting the rotating block in the four-way auxiliary block 25 to rotate in the opposite direction, thereby driving the folding rotating rods 27 connected to the other three connecting columns on the four connecting columns of the four-way auxiliary block 25 to deflect, so that the four folding rotating rods 27 synchronously perform reverse deflection movement, and then the outer slider 29 fixedly connected to the inner slider 28 synchronously moves linearly in the four-way straight groove 22 toward the center of the four-way auxiliary block 25, and the centering slide 210 fixedly connected above it gradually approaches the periphery of the die-casting mold 23 under the displacement of the outer slider 29, until, under the cooperation of multiple structures, the centering slide 210 pushes the positioning body 35 to fit the surrounding surfaces of the upper and lower molds of the die-casting mold 23, providing positioning and vertical guiding functions for them.

[0047] By setting the positioning locking guide mechanism 2, under the telescopic control of the electric telescopic rod 24, the position of the inner slider 28 and the outer slider 29 is changed to realize the positioning and guiding function of the die-casting mold 23. The die-casting mold 23 is fine-tuned in four directions, and the position of the upper and lower molds in the die-casting mold 23 can be adjusted more accurately to ensure that the upper and lower molds have a high verticality when merged, thereby improving the centering accuracy, helping to reduce the misalignment and deviation between the molds, and improving the dimensional accuracy and quality stability of the die-casting parts. The improvement of the verticality of the merger enables the metal liquid to evenly fill the mold cavity during the die-casting process, reducing defects such as flash and burrs caused by uneven mold gaps, and helping to improve the surface quality and internal quality of the die-casting parts.

[0048] Please refer to the above working process Figures 1 to 6 .

[0049] The following is a working process of the elastic buffer mechanism 3 for performing positioning adaptation functions according to different die-casting mold 23 specifications and improving the sealing performance during closing:

[0050] During use, during the operation of the positioning and locking guide mechanism 2, when the four centering slides 210 simultaneously approach and fit toward the four sides of the die-casting mold 23, the movement of the centering slide 210, in cooperation with the electromagnetic column 31, the cover tube 32, and the return spring body 34, pushes the positioning body 35 to move synchronously toward the die-casting mold 23 until the four positioning bodies 35 are all in contact with the four sides of the die-casting mold 23. Since the die-casting mold 23 is rectangular, when the positioning body 35 moves to fit the surface of the die-casting mold 23, when its length and width are inconsistent, the long two sides of the die-casting mold 23 first contact the positioning body 35, and in the process of continuous movement of the positioning body 35, two of the positioning bodies 35, under the action of the resistance force of the die-casting mold 23, prompt the cover tube 32 to move toward the electromagnetic column. 31 direction, at this time the return spring body 34 is compressed, and the distance between the cover tube 32 and the electromagnetic column 31 provides a buffer space for the movement of the positioning body 35. Then, when it continues to move, until the other two positioning bodies 35 are in contact with the wide sides of the die-casting mold 23, under the action of the pressure sensor on the surface of the positioning body 35, feedback is sent to the main controller. At this time, the four positioning bodies 35 are in contact with the surface of the die-casting mold 23. When the main controller receives the pressure signal, the built-in driving source of the electromagnetic column 31 is started and energized to generate magnetic force. Under the action of this magnetic force, the magnetorheological fluid 33 is solidified, fixing the position of the centering slide 210 and the positioning body 35, and positioning the vertical surfaces of the upper and lower molds of the die-casting mold 23, thereby assisting in the symmetry of the upper and lower molds in the die-casting mold 23.

[0051] Furthermore, during the process of the positioning body 35 approaching and fitting the die-casting mold 23, the buffer pad 39 gradually moves to the middle of the merging surface of the two molds of the die-casting mold 23 as the positioning body 35 moves, and when the upper mold and the lower mold in the die-casting mold 23 merge, the buffer pad 39 gradually approaches the buffer pad 39, and during the downward movement of the upper mold, the buffer pad 39 is pushed toward the lower mold. At this time, under the cooperation of the sleeve group 37 and the auxiliary spring body 38, the circular slider in the buffer pad 39 moves downward in the inner groove 36, the auxiliary spring body 38 is stretched, and the sleeve group 37 extends synchronously, assisting the movement and subsequent reset of the buffer pad 39. When the upper and lower molds in the die-casting mold 23 merge, the buffer pad 39 is embedded in the edges of the die-casting mold 23, and then when the two molds move in alignment, the impact force of the collision is absorbed to avoid damage caused by rigid contact. In addition, during the merging process, the elastic deformation of the buffer pad 39 can adaptively fill the small gap, thereby improving the tightness of the closure of the die-casting mold 23.

[0052] Through the setting of the elastic buffer mechanism 3, when the positioning body 35 is fitted with the surface of the die-casting mold 23, there is a buffer space between it and the centering slide 210 through the cooperation of the electromagnetic column 31, the cover tube 32 and the return spring body 34, so that it can be adapted to the die-casting molds 23 of different sizes and specifications, and is not limited to the die-casting molds 23 of a specific size. It shortens the production preparation time, improves the production flexibility and response speed, can quickly verify the die-casting effects of molds of different sizes, timely adjust product design and mold structure, improve R&D efficiency, and reduce production downtime caused by equipment replacement or mold incompatibility.

[0053] By setting the buffer pad 39, the impact force generated when the upper and lower molds in the die-casting mold 23 are merged can be effectively absorbed, the rigid collision between the die-casting molds 23 can be reduced, and the wear, deformation, cracks and other damages on the merged surface of the die-casting mold 23 can be reduced, thereby extending the service life and reducing the maintenance and replacement costs. Furthermore, the elastic deformation of the buffer pad 39 can adaptively fill the tiny gaps on the merged surface of the die-casting mold 23, preventing the metal liquid from overflowing from these gaps during the die-casting process, avoiding the generation of flash, and improving the molding quality and appearance quality of the casting.
