Description

Technical Field

[0001] The present application relates to the field of die-casting devices, and in particular to a die-casting mold with a multi-faceted core-pulling function. Background Art

[0002] A die-casting mold is a tool used to cast metal parts, performed on a dedicated die-casting forging machine. The basic die-casting process involves molten metal being poured into the mold cavity at either a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools. This eliminates shrinkage defects in the blank and achieves a forged, crushed grain structure within the blank.

[0003] In the related art, if the side of the workpiece has a concave-convex structure, a slider insert is needed to realize it, and one slider insert corresponds to one side. In order to manufacture more efficiently, if multiple sides of the workpiece have concave-convex structures, multiple slider inserts will be used to realize it. However, if the sides are not perpendicular or parallel to each other, the core-pulling component matched with the slider insert will conflict with the guide rod on the mold.

[0006] By adopting the above technical solution, due to the setting of the motion conversion block, multiple slider inserts can be moved away from the center of the workpiece through only one rear mold slide seat, and the movement paths of the multiple slider inserts are intersecting, so there will be no conflict between the rear mold slide seat and the mold guide rod when demolding is achieved, thereby making it possible to produce workpieces with side surfaces that are not perpendicular or parallel to each other and have a concave and convex structure.

[0008] By adopting the above technical solution, the slider insert and the motion conversion block are detachably connected, and the connection structure is relatively simple, so it is easier for the rear mold position seat to drive the slider insert to move more accurately.

[0009] Preferably, the motion conversion block is slidably connected to the rear mold slide seat, the motion conversion block moves horizontally, and the movement direction of the motion conversion block is perpendicular to the movement direction of the rear mold slide seat.

[0010] By adopting the above technical solution, the distance between two adjacent slider inserts can be changed, so that two non-directly adjacent side surfaces that are farther apart can be adapted.

[0011] Preferably, the motion conversion block includes a slide connection part and an insert connection part, the slide connection part is connected to the rear mold slide seat, one end of the insert connection part is rotatably connected to the slide connection part, and the other end is connected to the slider insert.

[0012] By adopting the above technical solution, the insert connecting part and the slide connecting part are rotatably connected, which can adapt to the two side surfaces with different angle relationships, and can also change the transmission ratio between the rear mold slide seat and the slider insert to adapt to different demoulding parameters.

[0013] Preferably, the slide connection portion and the insert connection portion are in a multi-section telescopic structure.

[0014] By adopting the above technical solution, two side surfaces with different distances from the center of the workpiece can be adapted.

[0015] Preferably, a first rotating shaft, a transfer block and a second rotating shaft are provided between the slide connecting part and the insert connecting part, the first rotating shaft rotatably passes through the slide connecting part, and the axis of the first rotating shaft extends horizontally; the transfer block is fixedly mounted on the first rotating shaft; the second rotating shaft is provided on the transfer block, the second rotating shaft is perpendicular to the first rotating shaft, and the second rotating shaft is rotatably connected to the insert connecting part.

[0016] By adopting the above technical solution, with the help of the cooperation between the first rotating shaft and the second rotating shaft, universal rotation between the insert connecting part and the slide connecting part can be achieved, so that workpieces with non-vertical sides and horizontal surfaces can be adapted.

[0017] Preferably, the sliding connection portion is provided with a positioning slot at a location where the first rotating shaft passes through, and the positioning slot is slidably provided with a positioning slider, and the positioning slider is rotatably provided for the first rotating shaft.

[0021] Preferably, balls are embedded on the surface of the slider insert that does not form the cavity.

[0022] By adopting the above technical solution, since the rear mold slide seat does not directly apply a force parallel to the movement direction of the slider insert, the setting of the ball can reduce the friction force on the slider insert, thereby making the demoulding of the slider insert smoother.

This allows the production of workpieces with non-perpendicular or non-parallel side surfaces and concave-convex structures. 2. With the help of the cooperation between the first rotating shaft and the second rotating shaft, universal rotation between the insert connecting part and the slide connecting part can be achieved, so that workpieces with non-vertical sides and horizontal surfaces can be adapted.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a die-casting mold with a multi-faceted core-pulling function.

[0030] Reference Figure 1 and Figure 2 The die-casting mold with multi-faceted core pulling function includes a base 1, a fixed mold plate 11, a rear mold core 12, a rear mold slide seat 2, a slider insert 3, a motion conversion block 4, a movable mold plate 5, a front mold core 51 and a guide rod 52. The fixed mold plate 11 is fixedly arranged on the base 1; the rear mold core 12 is fixedly mounted on the upper end surface of the fixed mold plate 11; the rear mold slide seat 2 is horizontally slidably arranged on the upper end surface of the fixed mold plate 11; the slider insert 3 is slidably arranged on the rear mold core 12, and the motion path of the slider insert 3 intersects with the motion path of the rear mold slide seat 2; one end of the motion conversion block 4 is connected to the rear mold slide seat 2, and the other end is slidably connected to the slider insert 3, and the motion conversion block 4 moves in a direction orthogonal to the motion direction between the rear mold slide seat 2 and the slider insert 3; the movable mold plate 5 is vertically slidably arranged on the base 1; the front mold core 51 is fixedly arranged on the movable mold plate 5; one end of the guide rod 52 is connected to the movable mold plate 5, and the other end slides through the rear mold slide seat 2.

[0031] Reference Figure 1 and Figure 2 Due to the setting of the motion conversion block 4, only one rear mold slide seat 2 is needed to allow multiple slider inserts 3 to move away from the center of the workpiece, and the movement paths of the multiple slider inserts 3 are intersecting, so there will be no conflict between the rear mold slide seat 2 and the mold guide rod 52 when demolding is achieved, so that a workpiece with side surfaces that are not perpendicular or parallel to each other and have a concave and convex structure can be made. It should be noted that in the case of non-perpendicularity, the two side surfaces can be adjacent or non-adjacent, and in the case of non-parallelness, they can only be non-adjacent side surfaces.

[0032] In addition, in this embodiment, considering that the rear mold slide seat 2 does not directly apply a force parallel to the movement direction of the slider insert 3, in order to improve the movement smoothness of the slider insert 3, balls are embedded on the surface of the slider insert 3 that does not form the cavity, which can reduce the friction force on the slider insert 3, thereby making the demolding of the slider insert 3 smoother.

[0033] Reference Figure 1 and Figure 2 In order to make it easier to connect the motion conversion block 4 and the slider insert 3, the motion conversion block 4 and the slider insert 3 are embedded in a T-shaped slider groove, so the slider insert 3 and the motion conversion block 4 are detachably slidingly connected. At the same time, the connection structure is relatively simple, so it is easier for the rear mold position seat 2 to drive the slider insert 3 to move more accurately.

[0034] Reference Figure 1 and Figure 2 If you want to adapt to two side surfaces that are not directly adjacent, you also need to consider the distance between the two side surfaces. Therefore, the following settings are correspondingly made: the motion conversion block 4 is slidingly connected to the rear mold slider seat 2, the motion conversion block 4 moves horizontally, and the movement direction of the motion conversion block 4 is perpendicular to the movement direction of the rear mold slider seat 2. The distance between the two adjacent slider inserts 3 can be changed, so that two side surfaces that are farther away and not directly adjacent can be adapted.

[0035] Reference Figure 2 and Figure 3 In order to improve the adaptability of the slider insert 3, the following settings are correspondingly provided. First, the motion conversion block 4 includes a slide connection part 41 and an insert connection part 42. The slide connection part 41 is connected to the rear mold slide seat 2. One end of the insert connection part 42 is rotatably connected to the slide connection part 41. The rotation direction can be horizontal swing. The other end is connected to the slider insert 3. The insert connection part 42 can be rotatably connected to the slide connection part 41 to adapt to the two side surfaces with different angle relationships. In addition, the transmission ratio between the rear mold slide seat 2 and the slider insert 3 can also be changed to adapt to different demolding parameters.

[0036] Reference Figure 2 and Figure 3Secondly, the slide connection part 41 and the insert connection part 42 are multi-section telescopic structures, which can also be self-locking, that is, they can be kept at different lengths, so the distance between the slider insert 3 and the center of the workpiece can be changed, so it can also adapt to two sides with different distances from the center of the workpiece; thirdly, a first rotating shaft 6, a transfer block 61 and a second rotating shaft 62 are provided between the slide connection part 41 and the insert connection part 42. The first rotating shaft 6 is damped and rotated through the slide connection part 41. The axis of the first rotating shaft 6 extends horizontally. The transfer block 61 is fixedly sleeved on the first rotating shaft On the shaft 6, the second rotating shaft 62 is fixedly set on the transfer block 61, and the second rotating shaft 62 is perpendicular to the first rotating shaft 6. The second rotating shaft 62 is rotatably passed through the insert connecting part 42. With the help of the cooperation between the first rotating shaft 6 and the second rotating shaft 62, the universal rotation between the insert connecting part 42 and the slide connecting part 41 can be achieved, so that it can adapt to workpieces that are not perpendicular between the side and the horizontal plane. At the same time, the end of the second rotating shaft 62 can be exposed outside the insert connecting part 42 and connected with a nut to lock the two after the insert connecting part 42 and the slide connecting part 41 are adjusted to a predetermined angle.

[0037] Reference Figure 2 and Figure 3 Fourthly, the sliding connection part 41 is provided with a positioning slide 7 at the penetration of the first rotating shaft 6. The positioning slide 7 is extended vertically, and the positioning slide 7 is slidingly provided with a positioning slider 71. At the same time, the positioning slider 71 can also be locked in different positions by bolts. The positioning slider 71 is provided for the first rotating shaft 6 to rotate, and the first rotating shaft 6 can change its position in the vertical direction, so it can adapt to more inclined and horizontal side surfaces, for example, it can adapt to inclined side surfaces with different positions as the rotation center, thereby helping to improve the adaptability of the mold.

[0038] Reference Figure 1 and Figure 2 In order to adapt to different numbers of side processing requirements, the motion conversion block 4 and the rear mold slide seat 2 are detachably connected. According to the needs, the corresponding number of motion conversion blocks 4 can be installed to adapt to different numbers of slider inserts 3.

[0039] The implementation principle of a die-casting mold with a multi-sided core-pulling function in an embodiment of the present application is as follows: due to the setting of the motion conversion block 4, only one rear mold slide seat 2 is needed to allow multiple slider inserts 3 to move away from the center of the workpiece, and the movement paths of the multiple slider inserts 3 are intersecting, so there will be no conflict between the rear mold slide seat 2 and the mold guide rod 52 when demolding is achieved, thereby enabling a workpiece with side surfaces that are not perpendicular or parallel to each other and having a concave and convex structure to be made.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
