[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] A high-performance die-casting mold with a movable insert for molding product undercuts, comprising a mold body 1, and a cavity 10, and also comprising a primary slide insert 2 arranged on the mold body 1 and cooperating with the cavity 10 to form a primary undercut of the product, a movable insert 3 arranged on the primary slide insert 2 and cooperating with the primary slide insert 2 and the cavity 10 to form a secondary undercut of the product, and a primary demolding mechanism 4 arranged on the mold body 1 for allowing the primary slide insert 2 to withdraw from the cavity 10 and disengage from the movable insert 3, wherein the movable insert 3 can withdraw from the cavity 10 after disengaging from the primary slide insert 2.

[0029] The present embodiment provides a high-performance die-casting mold with a movable insert for molding product undercuts, including a mold body and a cavity, and also including a first-level slide insert arranged on the mold body and cooperating with the cavity to form a first-level undercut of the product, a movable insert arranged on the first-level slide insert and cooperating with the first-level slide insert and the cavity to form a second-level undercut of the product, and a first-level demoulding mechanism arranged on the mold body for making the first-level slide insert exit the cavity and separate from the movable insert, and the movable insert can exit the cavity after separating from the first-level slide insert. The first-level slide insert corresponds to the first-level buckle position of the product, and the movable insert corresponds to the second-level buckle position of the product. When demoulding, the first-level demoulding mechanism makes the first-level slide insert exit the first-level buckle position and separate from the movable insert at the same time. After the movable insert separates from the first-level slide insert, it can be separated from the second-level buckle position of the product, so that when the product has multiple buckle positions, it can be die-casted at one time, without the need for post-processing, and can meet the assembly use, which not only improves efficiency, but also reduces production costs and increases the profits of the enterprise.

[0030] Further, as a preferred embodiment of the present solution but not a limitation, the mold body 1 is provided with a secondary demolding mechanism 5 for separating the movable insert 3 from the mold cavity 10 after the primary slide insert 2 exits the mold cavity 10 and separates from the movable insert 3 .

[0031] The primary demoulding mechanism enables the primary slide insert to exit the cavity, that is, exit the primary buckle position of the product, and separate from the movable insert. After the movable insert separates from the primary slide insert, it loses the restriction of the primary slide insert, so that the movable insert can exit the secondary buckle position of the product. The secondary demoulding mechanism is used to enable the movable insert to exit the secondary buckle position of the product.

[0032] Further, as a preferred implementation of the present solution but not limiting, the secondary demoulding mechanism 5 includes an ejector pin ejector 51 for separating the movable insert 3 from the product when ejecting the product from the mold.

[0033] The ejector pin ejector device ejects the product in the direction of the movable insert being separated from the secondary buckle position of the product. In the process of ejecting the product, the movable insert is separated from the secondary buckle position of the product to achieve the demoulding effect. In this embodiment, the ejector pin ejector device includes ejector pin plates 005, 006, and ejector pins 511.

[0034] Further, as a preferred implementation manner of the present solution but not a limitation, when the ejector pin ejection device 51 ejects the product from the mold, the movable insert 3 is separated from the secondary undercut position of the product under the action of gravity.

[0035] The ejector device ejects the product vertically upwards, and the ejection direction is the direction in which the movable insert is separated from the secondary buckle position of the product. Since the movable insert moves vertically downward to separate from the secondary buckle position of the product, during the process of ejecting the product, the movable insert is affected by gravity and separates from the secondary buckle position of the product under the action of gravity. The demoulding effect is best at this time.

[0036] Furthermore, as a preferred implementation of the present solution but not a limitation, the first-level slide insert 2 includes a first-level slide insert 21 plugged into the movable insert 3, and the first-level demolding mechanism 4 includes a first-level demolding mechanism 41 for driving the first-level slide insert 21 to move in a direction of exiting the cavity 10.

[0037] The first-level slide insert is plugged into the movable insert, which is simple and reliable, and is conducive to mold installation and demoulding. The first-level demoulding mechanism is used to drive the first-level slide insert to move in the demoulding direction and also in the direction of separation from the movable insert, so as to separate from the movable insert during demoulding, thereby avoiding the need for a complex structure to be manufactured separately for the mold to enable the first-level demoulding mechanism to demould and separate from the movable insert for multiple movements.

[0038] In this embodiment, the first level demoulding mechanism 41 includes a first hydraulic cylinder 502 and a first slide seat 401. The first hydraulic cylinder 502 drives the first level slide insert 21 to be demoulded through the first slide seat 401.

[0039] Further, as a preferred implementation manner of the present solution but not limiting, the movable insert 3 is provided with a dovetail groove 31 , and the first-level slide insert 21 is provided with a slot 211 for cooperating with the dovetail groove 31 .

[0040] In this embodiment, the dovetail groove is T-shaped, and the dovetail groove cooperates with the slot so that the movable insert and the first-stage slide insert can only be separated from each other in a single direction.

[0041] Furthermore, as a preferred implementation of the present solution but not a limitation, the first-level slide insert 2 also includes a second-level slide insert 22 provided on the mold body 1 for pressing on the movable insert 3 so that the movable insert 3 maintains a mating state with the first-level slide insert 21 and cooperates with the cavity 10 to form an inverted position of the product, and the first-level demolding mechanism 4 includes a second-level demolding mechanism 42 for driving the second-level slide insert 22 to move in a direction of exiting the cavity 10.

[0042] The first-level buckle of the product includes the buckle between the first-level slide insert and the product, and the buckle between the second-level slide insert and the product. The second-level slide insert presses on the movable insert to limit the movable insert, thereby preventing the movable insert from shifting during the die-casting process, resulting in product scrapping and even mold collision. If the second-level slide insert is not demolded from the product, the movable insert cannot be separated from the first-level slide insert.

[0043] In this embodiment, the second first-level demoulding mechanism 42 includes a second hydraulic cylinder 501 and a second slide seat 402. The second hydraulic cylinder 501 drives the second first-level slide insert 22 to be demoulded through the second slide seat 402.

[0044] Furthermore, as a preferred implementation of the present solution but not a limitation, the mold body 1 is also provided with a third first-level slide insert 23 for cooperating with the cavity 10 to form an inverted position of the product, and the first-level demolding mechanism 4 includes a third first-level demolding mechanism 43 for driving the third first-level slide insert 23 to move in a direction of exiting the cavity 10.

[0045] The first-level snap-in position of the product includes the snap-in position between the first-level slide insert and the product, the snap-in position between the second-level slide insert and the product, and the snap-in position between the third-level slide insert and the product. In this embodiment, after the second-level slide insert and the product are demolded, after the first-level slide insert and the product are demolded, after the third-level slide insert and the product are demolded, the movable insert and the product can be ejected by the second-level demolding mechanism, that is, the ejector ejection device. The third-level slide insert is used to cooperate with the snap-in position of the product and ensure that the snap-in positions of the product other than the second-level snap-in position are demolded. At this time, the mold completes the first-level demolding stage and the mold can enter the second-level demolding stage.

[0046] In this embodiment, the third level demoulding mechanism 43 includes a third hydraulic oil cylinder and a third slide seat 415. The third hydraulic oil cylinder drives the third level slide insert 23 to be demoulded through the third slide seat 415.

[0047] Furthermore, as a preferred implementation of the present solution but not limiting, the mold body 1 is further provided with a side pouring system 6 for feeding material from the side of the cavity 10 .

[0048] Furthermore, as a preferred embodiment of the present invention but not limiting, the side pouring system 6 includes a fixed mold runner plate 61 provided on the fixed mold plate and a movable mold runner plate 62 provided on the movable mold plate, and the fixed mold runner plate 61 and the movable mold runner plate 62 together form a runner channel 63 connected to the side of the cavity 10.

[0049] As shown in FIG. 2 and FIG. 4 , the mold includes a fixed mold plate 001, a movable mold plate 002, a fixed mold core 101, and a movable mold core 201. The fixed mold core is fixed on the fixed mold plate, and the movable mold core is fixed on the movable mold plate. The cavity formed by the closed fixed mold core and the movable mold core is the mold cavity of the casting, which is used to form the product. The side pouring system is mainly composed of a fixed mold runner plate 61 and a movable mold runner plate 62.

[0050] The fixed mold runner plate is fixed on the fixed mold plate, and the movable mold runner plate is fixed on the movable mold plate. These components together form a material chamber and a runner channel 63, and the runner channel connects the side of the product. This is a gating system that feeds from the side of the product. It is relatively simple to remove the water inlet when feeding from the side, and the die casting parameters can be adjusted to a large extent, reducing the occurrence of scrapped products.

[0051] The working principle of this embodiment is as follows:

[0052] The second hydraulic cylinder 501, the second slider seat 402, the first hydraulic cylinder 502, the first slider seat 401, the third hydraulic cylinder, the third first-level slider insert 23, the third slider seat 415, and the ejector plates 005 and 006.

[0053] The working steps of a high-performance die-casting mold with a movable insert to form a product undercut are as follows:

[0054] 1. Under the action of the mechanical force of the die-casting machine, the fixed platen and the movable platen are separated first.

[0055] 2. After the die casting machine is fully opened, the second hydraulic cylinder 501 drives the second first-stage slide insert 22 to be pulled out of the product along the movement direction of the second slide seat 402.

[0056] 3. The first hydraulic cylinder 502 drives the first level slide insert to be pulled out from the product along the movement direction of the first slide seat 401, and the movable insert 3 is separated from the first level slide insert 21 along the T-shaped dovetail groove 31. At this time, the movable insert 3 is still connected to the product.

[0057] 4. The third hydraulic cylinder drives the third first-stage slide insert 23 to be pulled out from the product along the movement direction of the third slide seat 415. At this time, the first first-stage slide insert 21, the first second-stage slide insert 22 and the third first-stage slide insert 23 are completely separated from the product.

[0058] 5. The ejector plates 005 and 006 drive the product to be ejected. After the product is ejected and placed horizontally, the movable insert 3 is automatically separated from the product by the vertical gravity.

[0059] Here, the movable insert 3 is ensured to be separated from the first-level slide insert 21 by the mechanism of the T-shaped dovetail groove. The structural schematic diagram of the movable insert 3 is shown in FIG7. When the mold is in the mold opening state. The first slide seat 401 and the first-level slide insert 21 are pulled out by the first hydraulic cylinder 502, forcing the movable insert 3 to separate from the first-level slide insert. Then the product is ejected, the product is taken out, and the movable insert is separated from the product. In this way, a production cycle of the product is completed.

[0060] The first-level buckle position of the product includes the buckle position between the first-level slide insert and the product, the buckle position between the second-level slide insert and the product, and the buckle position between the third-level slide insert and the product. In this embodiment, after the second-level slide insert and the product are demolded, after the first-level slide insert and the product are demolded, after the third-level slide insert and the product are demolded, the movable insert and the product can be ejected by the second-level demolding mechanism, that is, the ejector ejection device. The third-level slide insert is used to cooperate with the buckle position of the product and ensure that the buckle positions of the product other than the second-level buckle position are demolded. At this time, the mold completes the first-level demolding stage and the mold can enter the second-level demolding stage.

[0061] The present embodiment provides a high-performance die-casting mold with a movable insert for molding product undercuts, including a mold body and a cavity, and also including a first-level slide insert arranged on the mold body and cooperating with the cavity to form a first-level undercut of the product, a movable insert arranged on the first-level slide insert and cooperating with the first-level slide insert and the cavity to form a second-level undercut of the product, and a first-level demoulding mechanism arranged on the mold body for making the first-level slide insert withdraw from the cavity and separate from the movable insert, and the movable insert can withdraw from the cavity after separating from the first-level slide insert. The first-level slide insert corresponds to the first-level buckle position of the product, and the movable insert corresponds to the second-level buckle position of the product. When demoulding, the first-level demoulding mechanism makes the first-level slide insert withdraw from the first-level buckle position and separate from the movable insert at the same time. After the movable insert separates from the first-level slide insert, it can be separated from the second-level buckle position of the product, so that when the product has multiple buckle positions, it can be die-casted at one time, without the need for post-processing, and can meet the assembly use, which not only improves efficiency, but also reduces production costs and increases the profits of the enterprise.

[0062] The fixed mold runner plate is fixed on the fixed mold plate, and the movable mold runner plate is fixed on the movable mold plate. These components together form a material chamber and a runner channel 63, and the runner channel is connected to the side of the product. This is a gating system that feeds from the side of the product. It is relatively simple to remove the water inlet when feeding from the side, and the die casting parameters can be adjusted to a large extent, reducing the occurrence of scrapped products.
