Description

Technical Field

[0001] This utility model belongs to the field of zinc alloy die casting technology, specifically relating to a multi-slider die casting mold. Background Technology

[0002] During zinc alloy die casting, the injection pressure is extremely high (usually several hundred to thousands of atmospheres). This enormous pressure acts like an "inflating balloon," attempting to push the mold open from the parting line. The clamping force is the force applied to the mold by the die casting machine to prevent it from being pushed open. When the expansion force generated by the molten metal exceeds the machine's clamping force, tiny, invisible gaps will appear on the parting line of the mold. The high-pressure molten metal will then be squeezed into these gaps instantly, forming flash. Furthermore, after long-term use, the parting line will no longer be smooth, and the gaps will widen, seriously affecting the quality and yield of the product. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides a multi-slider die-casting mold, which aims to solve the problem that gaps are easily generated in the mold during injection, thus affecting product quality.

[0006] This utility model provides a multi-slider die-casting mold, including a fixed frame and a first mold core and a second mold core disposed within the fixed frame. The first mold core and the second mold core are provided with cavities and injection channels. There are at least two cavities, which are respectively located on both sides of the injection channel. The fixed frame is also provided with a slider assembly and an ejector assembly. The ejector assembly is disposed within the slider assembly. The slider assembly includes at least a first slider and a second slider that are respectively connected to the first mold core and the second mold core. The movement of the first slider and the second slider can respectively drive the movement of the first mold core and the second mold core.

[0007] It also includes a first component and a second component with the same structure and interlocking with each other. The first component and the second component are respectively disposed on the first mold core and the second mold core, and are used to lock the mold core and the second mold core together.

[0008] Furthermore, the injection channel extends to the outer wall of the first mold core and the second mold core to form an injection port, and the injection port is located on different sides opposite to the first mold core and the second mold core, respectively.

[0009] Furthermore, the fixing frame includes a first bracket and a second bracket that are detachably connected. The first bracket has a first opening corresponding to the injection port, and the second bracket has a second opening corresponding to the positions of the first component and the second component.

[0010] Furthermore, the first mold core and the second mold core are respectively provided with grooves, the first component and the second component are respectively located in the grooves, and the outer surfaces of the first component and the second component are flush with the outer surfaces of the first mold core and the second mold core.

[0011] Furthermore, the first component includes a mounting bracket, a connector, and an unlocking component. The mounting bracket is screwed to the first mold core, the connector is located inside the mounting bracket and rotatably connected to the mounting bracket, the connector is provided with a locking position, and one end of the unlocking component slides against the locking position to control the unlocking or unlocking state of the first component and the second component.

[0012] Furthermore, the slider assembly also includes a third slider and a fourth slider, which are respectively located on two end faces of the first mold core and the second mold core perpendicular to the mold closing direction. The fixing frame is provided with grooves corresponding to the first slider, the second slider, the third slider and the fourth slider respectively.

[0013] Furthermore, the end of the unlocking component away from the connecting component is connected to the third slider or the fourth slider, and the movement of the third slider or the fourth slider can synchronously drive the unlocking component to move.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figure 1-3As shown, this utility model provides a multi-slider die-casting mold, including a fixed frame 1 and a first mold core 11 and a second mold core 12 disposed within the fixed frame 1. The first mold core 11 and the second mold core 12 are provided with cavities 13 and injection channels 14. At least two cavities 13 are provided and located on both sides of the injection channel 14, facilitating the simultaneous production of multiple products in a single injection, thereby improving production efficiency. The fixed frame 1 also provides a slider assembly 2 and an ejector assembly 3. The ejector assembly 3 is disposed within the slider assembly 2. The slider assembly 2 includes at least a first slider 21 and a second slider 22 respectively connected to the first mold core 11 and the second mold core 12. The movement of the first slider 21 and the second slider 22 can respectively drive the movement of the first mold core 11 and the second mold core 12. Therefore, the opening and closing of the first mold core 11 and the second mold core 12 are driven by the first slider 21 and the second slider 22. In order to further improve the tightness of the closure after mold closing and avoid the impact of the injection wave on the first mold core 11 and the second mold core 12, this utility model also includes two identical and interlocking first components 4 and second components 5. The first components 4 and the second components 5 are respectively provided on the first mold core 11 and the second mold core 12, and are used to lock the mold closing of the first mold core 11 and the second mold core 12. Specifically, when the mold is closed, the first components 4 and the second components 5 interlock to apply a stable pressure to the first mold core 11 and the second mold core 12 in the mold closing direction, effectively controlling the possibility of gaps being generated on the parting surface of the first mold core 11 and the second mold core 12.

[0035] Specifically, such as Figure 3-4 As shown, the injection channel 14 extends to the outer wall of the first mold core 11 and the second mold core 12 to form an injection port 15. The injection port 15 is located on different sides of the first mold core 11 and the second mold core 12, respectively, to avoid interference between the first mold core 4 and the second mold core 5 and the syringe. The fixing frame 1 includes a first bracket 16 and a second bracket 17 that are detachably connected. The first bracket 16 has a first opening 161 corresponding to the injection port 15, which allows the syringe to connect to the injection port 15 through the first opening 161 to inject molten metal into the cavity 13. The second bracket 17 has a second opening 171 corresponding to the positions of the first mold core 4 and the second mold core 5, which allows the product to be removed through the second opening 171 after the mold is opened. This makes the material inlet and outlet located in two opposite directions, without affecting each other, thereby improving the convenience of use.

[0036] Furthermore, the first mold core 11 and the second mold core 12 are respectively provided with grooves 18, the first component 4 and the second component 5 are respectively located in the grooves 18, and the outer surfaces of the first component 4 and the second component 5 are flush with the outer surfaces of the first mold core 11 and the second mold core 12, making the present invention neater and more beautiful overall, while also providing protection for the first component 4 and the second component 5, preventing them from being hit, extending their service life and ensuring their stability in use.

[0037] Furthermore, such as Figure 5-7 As shown, the first component 4 includes a mounting bracket 41, a connector 42, and an unlocking component 43. The mounting bracket 41 is screwed to the first mold core 11. The connector 42 is located inside the mounting bracket 41 and is rotatably connected to the mounting bracket 41. The first mold core 11 has a connector 42 that is adapted to the unlocking component 43, and the connector 42 of the first component 4 and the connector 42 of the second component 5 rotate in opposite directions, so that the two connectors 42 are in a mutually engaging state. The connector 42 has a locking position 421. One end of the unlocking component 43 slides against the locking position 421. When the unlocking component 43 abuts against the locking position 421, the first component 4 is in a locked state. In the fixed state, the connecting piece 42 of the first component 4 is unable to rotate freely in the unlocking direction due to the limiting and abutting action of the unlocking piece 43, thereby keeping the two connecting pieces 42 in a tightly interlocked state to provide a mutual abutting force on the first mold core 11 and the second mold core 12, further enhancing the tightness of the mold closing; when the unlocking piece 43 separates from the locking position 421, the first component 4 is in the unlocked state, that is, the connecting piece 42 of the first component 4 is no longer restricted by the unlocking piece 43, and can automatically rotate within the mounting frame 41 as the first mold core 11 and the second mold core 12 are opened, thereby separating the two connecting pieces 42 from each other.

[0038] Preferably, such as Figure 8As shown, the mounting bracket 41 is further provided with an elastic positioning element 411, and the connecting element 42 is provided with a positioning hole 422 that matches the positioning element 411. The positioning element 411 can freely extend and retract within the mounting bracket 41. When the two connecting elements 42 rotate and can separate from each other, that is, when they are not in contact, the positioning element 411 corresponds to the positioning hole 422. At this time, one end of the positioning element 411 will automatically extend and insert into the positioning hole 422 to achieve a locking action, thereby keeping the connecting element 42 in the open state and preventing the two connecting elements 42 from rotating arbitrarily and affecting subsequent mold closing operations. This design not only improves the reliability of the mold closing structure but also simplifies the operation process, eliminating the need for manual adjustment of the angles of the two connecting elements 42, further improving the working efficiency and product quality of the die-casting equipment. In this embodiment, the positioning element 411 is an elastic glass ball screw.

[0039] Furthermore, such as Figure 9 As shown, the slider assembly 2 further includes a third slider 23 and a fourth slider 24. The third slider 23 and the fourth slider 24 are respectively located on two end faces of the first mold core 11 and the second mold core 12 perpendicular to the mold closing direction. The fixing frame 1 is provided with slide grooves 19 corresponding to the first slider 21, the second slider 22, the third slider 23 and the fourth slider 24 respectively, so that the first slider 21, the second slider 22, the third slider 23 and the fourth slider 24 slide more stably and accurately in the slide grooves 19, and the pressing force is also stronger. The end of the unlocking member 43 away from the connecting member 42 is connected to the third slider 23, so that the movement of the third slider 23 can synchronously drive the movement of the unlocking member 43.

[0040] Preferably, an upper fixed mold 6 and a lower fixed mold 7 are respectively provided on the end faces of the first mold core 11 and the second mold core 12 perpendicular to the mold opening direction. The upper fixed mold 6 and the lower fixed mold 7 are respectively snapped and fixed to the fixed frame 1 to restrict the movement of the first mold core 11 and the second mold core 12 in the longitudinal direction, thereby limiting and fixing the first mold core 11 and the second mold core 12 within the fixed frame 1.

[0041] Preferably, such as Figure 10As shown, to facilitate the installation of the unlocking component 43 and the third slider 23, a fifth slider 25 is provided on the side of the lower fixed mold 7 away from the first mold core 11. The fifth slider 25 is located between the third slider 23 and the lower fixed mold 7. One end of the unlocking component 43 is detachably connected to the fifth slider 25, and the other end passes through the fifth slider 25, the lower fixed mold 7, and the first mold core 11 in sequence to slide against the locking position 421. Specifically, the fifth slider 25 and the lower fixed mold 7 are respectively provided with a first through hole 251 and a second through hole 71. A limiting step 252 is provided in the first through hole 251, and the unlocking component 43 is provided with a limiting step 252. During installation, the unlocking member 43 is inserted into the bottom of the first through hole 251 of the fifth slider 25, so that the protrusion 431 abuts against the limiting step 252. In this embodiment, the fifth slider 25 and the third slider 23 are detachably connected and fixed by screws, so that the third slider 23 is sealed against the bottom end of the first through hole 251, thereby limiting and fixing the unlocking member 43 between the fifth slider 25 and the third slider 23. The other end of the unlocking member 43 can enter the first mold core 11 through the second through hole 71, so that the movement of the third slider 23 synchronously drives the movement of the fifth slider 25 and the unlocking member 43.

[0042] like Figure 11 As shown, in some embodiments, the end of the unlocking member 43 away from the connecting member 42 is connected to the fourth slider 24. The movement of the fourth slider 24 can synchronously drive the unlocking member 43 to move. In this case, the fifth slider 25 is disposed between the upper fixed mold 6 and the fourth slider 24, so that the movement of the fourth slider 24 synchronously drives the movement of the unlocking member 43. Its working principle is the same as that of the above embodiments, so it will not be described again here.

[0043] Furthermore, such as Figure 12-13 As shown, the slider assembly 2 also includes driving components (not shown in the figure) for driving each slider to slide. The output shaft of the driving component is connected to each slider. By driving the slider to move through the corresponding driving component, the first mold core 11 and the second mold core 12, as well as the first component 4 and the second component 5, can be driven to open and close. This avoids the need for additional driving components, thereby reducing the number of internal parts of the device, optimizing the internal structure, and increasing flexibility.

[0044] The second slider 22 is provided with a sliding cavity 221, and the ejector assembly 3 is disposed in the sliding cavity 221. The second slider 22 is also provided with a third opening 222 and a fourth opening 223 communicating with the sliding cavity 221. The output shaft of the drive member corresponding to the second slider 22 is connected to the ejector assembly 3 through the third opening 222, so that the drive member not only has the function of driving the second slider 22 to drive the second mold core 12 to open the mold with the first mold core 11, but also has the function of driving the ejector assembly 3 to demold the product from the second mold core 12.

[0045] Specifically, the ejector assembly 3 includes a face pin plate 31, a connecting shaft 32, a base plate 33, and a plurality of ejector pins 34. One end of the connecting shaft 32 is screwed to the face pin plate 31, and the other end is screwed to the base plate 33. One end of the ejector pin 34 is limited and fixed between the face pin plate 31 and the connecting shaft 32, and the other end extends into the second mold core 12 through the fourth opening 223 and forms part of the inner wall of the cavity 13. After the mold is opened, the ejector assembly 3 will move toward the second mold core 12 under the drive of the corresponding driving component, so that the ejector pins 34 can smoothly eject the product from the cavity 13 for the next injection.

[0046] It should be noted that the shape of the end of the connecting shaft 32 near the needle plate 31 is adapted to the shape of the needle plate 31, and the shape of the fourth opening 223 is also adapted to the shape of the needle plate 31. After installation, one end of the ejector pin 34 is embedded in the needle plate 31, and then the ejector pin 34 can be limited and fixed between the needle plate 31 and the connecting shaft 32 by the tight screw connection between the connecting shaft 32 and the needle plate 31. The connecting shaft 32 and the base plate 33 are both provided with connecting holes 35 coaxial with the third opening 222. The output shaft of the drive corresponding to the second slider 22 is screwed to the connecting shaft 32 through the third opening 222 and the connecting hole 35.

[0047] When the mold is opened, the base plate 33 abuts against the second slider 22 in the sliding cavity 221, causing the output shaft of the drive component to retract. At this time, the base plate 33 exerts an outward pushing force on the second slider 22 to synchronously drive the movement of the second slider 22. After the mold is opened, the output shaft of the drive component extends. At this time, the face pin plate 31, the connecting shaft 32, the base plate 33 and the ejector pin 34 move as a whole toward the second mold core 12 until the face pin plate 31 abuts against the second mold core 12. At this time, the ejector pin 34 protrudes into the cavity 13 and completes the action of ejecting the product from the cavity 13.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
