Description
Technical Field
[0001] This utility model belongs to the field of mold technology, and in particular relates to a mold mechanism. Background Technology
[0002] Casting is a method of pouring liquid metal into a casting cavity corresponding to the shape of a part, and then allowing it to cool and solidify to obtain the part or blank. Some electronic devices have metal casings with holes for mounting shafts, pins, etc. These casings are typically made of metal using casting processes. During the casting of the metal casing, pins are usually placed in the holes, and after the metal casing is cast, the pins need to be removed from the holes.
[0003] When a metal casing has two adjacent hole structures with different lengths, a mold mechanism needs to be equipped with two insert pins that are inserted into the two hole structures respectively. In the prior art, the two insert pins are fixed on a push block on the mold mechanism, and the push block simultaneously drives the two insert pins backward to be pulled out of the hole structure of the metal casing. However, since the distance between the two hole structures is relatively small, the two insert pins will affect each other, and the simultaneous movement of the two insert pins may easily damage the hole structure of the metal casing. Summary of the Invention
[0004] This utility model provides a mold mechanism to solve the technical problem in the prior art that the hole structure of the metal shell is easily damaged when two insert pins move simultaneously.
[0005] One embodiment of the present invention provides a mold mechanism, including a demolding component and a mold component, wherein the mold component is provided with a mold cavity and a groove communicating with the mold cavity;
[0006] The demolding assembly includes a first elastic element, a second elastic element, a demolding base, a first slider, a second slider, a first insert mounted on the first slider, and a second insert mounted on the second slider; the first slider is slidably mounted on the demolding base, and the second slider is slidably mounted in the groove;
[0007] The first elastic element is installed between the first slider and the second slider; the second slider is provided with a first through hole, one end of the second elastic element abuts against the first slider, and the other end of the second elastic element passes through the first through hole and abuts against the mold assembly;
[0008] The end of the first insert pin away from the first slider extends into the model cavity, and the end of the second insert pin away from the second slider extends into the model cavity.
[0009] Optionally, the demolding assembly further includes a demolding drive for moving the first slider on the demolding base.
[0010] Optionally, the demolding drive includes a support block with a first inclined surface and a demolding rod mounted on the support block. The first slider has an inclined hole and a second inclined surface adapted to the first inclined surface. The demolding rod is inserted into the inclined hole, and / or the first inclined surface abuts against the second inclined surface to drive the first slider to move.
[0011] Optionally, the second slider is provided with a second through hole, and the end of the first insert pin away from the first slider passes through the second through hole and extends into the model cavity.
[0012] Optionally, the mold mechanism further includes a guide member mounted on the mold assembly. The first slider has a guide hole, and the end of the guide member away from the mold passes through the inner hole of the second elastic member and slides into the guide hole.
[0013] Optionally, the demolding base includes a base plate and a first side plate and a second side plate located on opposite sides of the base plate. The base plate, the first side plate and the second side plate surround a sliding space, and the first slider is slidably installed in the sliding space.
[0014] Optionally, the demolding assembly further includes a guide pin mounted on the base plate, and the first slider is provided with a guide groove, the guide pin being slidably inserted into the guide groove.

[0018] In this invention, when the mold assembly is in the closed state, both the first insert and the second insert are located in the forming position of the mold cavity. After the molten metal is formed into a finished part in the mold cavity, the first insert forms a first hole structure in the finished part, and the second insert forms a second hole structure in the finished part. During the first demolding of this mold mechanism, the second elastic element drives the end away from the first slider to move, and the first slider drives the first insert away from its forming position.

[0033] like Figure 4 Of Figure 6 As shown, an embodiment of the present invention provides a mold mechanism, including a demolding component 1 and a mold component 2. The mold component 2 is provided with a mold cavity 21 and a groove 22 communicating with the mold cavity 21. Understandably, liquid metal is injected into the mold cavity 21, and the solidified liquid metal is formed into a finished part in the mold cavity 21. The groove 22 is disposed on the side of the mold cavity 21.
[0034] The demolding assembly 1 includes a first elastic element 11, a second elastic element 12, a demolding base 13, a first slider 14, a second slider 15, a first insert 16 mounted on the first slider 14, and a second insert 17 mounted on the second slider 15; the first slider 14 is slidably mounted on the demolding base 13, and the second slider 15 is slidably mounted in the slide groove 22; it is understood that the first elastic element 11 and the second elastic element 12 include, but are not limited to, springs.
[0035] The first elastic element 11 is installed between the first slider 14 and the second slider 15; the second slider 15 is provided with a first through hole 151, one end of the second elastic element 12 abuts against the first slider 14, and the other end of the second elastic element 12 passes through the first through hole 151 and abuts against the mold assembly 2; it can be understood that the opposite ends of the second elastic element 12 abut against the first slider 14 and the mold assembly 2 respectively.
[0036] The first pin 16 extends into the model cavity 21 at one end away from the first slider 14, and the second pin 17 extends into the model cavity 21 at one end away from the second slider 15. Understandably, the first pin 16 and the second pin 17 are positioned adjacent to each other.
[0037] Specifically, such as Figure 1 As shown, when the mold assembly 2 is in the closed state, both the first insert 16 and the second insert 17 are located at the forming position of the mold cavity 21. After the molten metal is formed into a finished part in the mold cavity 21, the first insert 16 forms a first hole structure in the finished part, and the second insert 17 forms a second hole structure in the finished part. Figure 2 As shown, during the first demolding of the mold mechanism, the second elastic element 12 moves the end away from the first slider 14, and the first slider 14 moves the first insert pin 16 away from its forming position. The deformation of the first elastic element 11 prevents the second slider 15 from moving, thus keeping the second insert pin 17 in the forming position. Figure 3As shown, during the secondary demolding of this mold mechanism, the first slider 14 continues to move towards the end away from the mold assembly 2, and the first elastic element 11 drives the second slider 15 to move towards the end away from the mold cavity 21. The second slider 15 drives the second insert pin 17 away from its forming position. In this utility model, the first insert pin 16 and the second insert pin 17 move in two stages, and the first insert pin 16 will not interfere with the second insert pin 17 during its movement. The first insert pin 16 and the second insert pin 17 can form two adjacent hole structures on the finished part, and the quality of manufacturing the two adjacent hole structures on the finished part is guaranteed.
[0038] In one embodiment, such as Figures 1 to 3 As shown, the demolding assembly 1 further includes a demolding drive 18 for moving the first slider 14 on the demolding base 13. It is understood that the demolding drive 18 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and lead screw and nut mechanisms, etc., and the demolding mechanism can drive the first slider 14 to move toward one end closer to the mold assembly 2.
[0039] In one embodiment, such as Figures 1 to 3 As shown, the demolding drive 18 includes a support block 181 with a first inclined surface 1811 and a demolding rod 182 mounted on the support block 181. The first slider 14 has an inclined hole 141 and a second inclined surface 142 adapted to the first inclined surface 1811. The demolding rod 182 is inserted into the inclined hole 141, and / or the first inclined surface 1811 abuts against the second inclined surface 142 to drive the first slider 14 to move. It can be understood that a lifting drive is mounted on the top of the support block 181, which can drive the support block 181 to move vertically.
[0040] Specifically, the support block 181 drives the demolding rod 182 to move downward, and the demolding rod 182 is inserted into the inclined hole 141. As a result, the demolding rod 182 drives the first slider 14 to move toward the end closer to the mold assembly 2, and the first slider 14 will compress the second elastic element 12. The first slider 14 also drives the second slider 15 to move toward the end closer to the mold cavity 21 through the first elastic element 11. The first insert 16 and the second insert 17 are both located at the forming position of the mold cavity 21. The first inclined surface 1811 abuts against the second inclined surface 142. The abutment between the first inclined surface 1811 and the second inclined surface 142 will make the support block 181 have a large clamping force on the first slider 14, ensuring the stability of the mold mechanism when the mold is closed.
[0041] The support block 181 drives the demolding rod 182 to move upward in the inclined hole 141. The second elastic element 12 drives the end away from the first slider 14 to move, and the first slider 14 drives the first insert pin 16 away from its forming position. The deformation of the first elastic element 11 makes the second slider 15 not move, so that the second insert pin 17 remains in the forming position.
[0042] The support block 181 drives the demolding rod 182 to disengage from the inclined hole 141. The first slider 14 continues to move toward the end away from the mold assembly 2, and the first elastic element 11 drives the second slider 15 to move toward the end away from the mold cavity 21. The second slider 15 drives the second insert pin 17 away from its forming position. In this embodiment, the demolding drive component 18 has a simple structure and high stability.
[0043] In one embodiment, the second slider 15 is provided with a second through hole (not shown in the figure), and the end of the first insert pin 16 away from the first slider 14 extends into the mold cavity 21 through the second through hole. Understandably, the first insert pin 16 and the second insert pin 17 are arranged adjacent to each other, and the first insert pin 16 can move within the first through hole 151. In this embodiment, the demolding assembly 1 has a compact structure and occupies little space.
[0044] In one embodiment, such as Figure 1 As shown, the mold mechanism further includes a guide member 3 mounted on the mold assembly 2. The first slider 14 has a guide hole 143. The end of the guide member 3 away from the mold assembly 2 passes through the inner hole of the second elastic member 12 and slides into the guide hole 143. Understandably, as the first slider 14 moves on the demolding base 13, the guide member 3 also moves. In this embodiment, the guide member 3 not only supports the second elastic member 12 but also guides it, ensuring the stability of the movement of the first slider 14.
[0045] In one embodiment, such as Figure 7 and Figure 8 As shown, the demolding base 13 includes a base plate 131 and a first side plate 132 and a second side plate 133 located on opposite sides of the base plate 131. The base plate 131, the first side plate 132, and the second side plate 133 enclose a sliding space, in which the first slider 14 is slidably mounted. Understandably, the left and right sides of the first slider 14 abut against the first side plate 132 and the second side plate 133 respectively, and the first slider 14 moves on the top surface of the base plate 131. In this embodiment, the demolding base 13 has a simple structure and low manufacturing cost.
[0046] In one embodiment, such as Figure 7 and Figure 8 As shown, the demolding assembly 1 also includes a guide pin (not shown) mounted on the base plate 131. The first slider 14 is provided with a guide groove 1311, and the guide pin is slidably inserted into the guide groove 1311. Understandably, the guide pin extends above the base plate 131, and the guide groove 1311 is located at the bottom of the first slider 14. During the movement of the first slider 14, the guide pin slides in the guide groove 1311, further ensuring the stability of the sliding of the first slider 14.
[0047] In one embodiment, such as Figure 7 As shown, the first slider 14 has a first step and a second step on opposite sides, respectively. The first step abuts against the first side plate 132, and the second step abuts against the second side plate 133. Understandably, the first side plate 132 can support the left side of the first slider 14 via the first step, and the second side plate 133 can support the right side of the first slider 14 via the second step.
[0048] In one embodiment, the mold assembly 2 includes a first mold (not shown) and a second mold (not shown), with the mold cavity 21 and the slide 22 both disposed between the first mold and the second mold. Understandably, the first mold and the second mold are the upper mold and the lower mold, respectively. After the first mold and the second mold are closed, the first mold and the second mold can seal the mold cavity 21, allowing liquid metal to be injected into the mold cavity 21, thereby completing the casting of the metal part.
[0049] In one embodiment, such as Figure 1 As shown, the mold mechanism further includes a mold closing drive component (not shown in the figure), which is connected to the first mold and is used to drive the first mold and the second mold to close or open. It can be understood that the mold closing drive component includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, lead screw and nut mechanisms, etc., and can drive the first mold to move up and down, thereby realizing the closing or opening of the first mold and the second mold.
