[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Reference below Figure 1-Figure 3 A mold device 100 according to an embodiment of the present invention is described.

[0029] like Figure 1 As shown, the mold device 100 according to the embodiment of the utility model includes: a first driving member 10, a driving body 11, a connecting member 12, a slider 20, an accommodating space 21, a spring needle assembly 30, a spring needle body 31, a mounting seat 32, a notch 321, a limit member 33, an elastic member 40, an insert 50, a workpiece to be processed 60 and a second driving member.

[0030] The first driving member 10 is transmission-connected to the slider 20 and is used to drive the slider 20 to move along the first direction so that the slider 20 approaches or moves away from the workpiece 60 to be processed. The slider 20 has a receiving space 21, and the receiving space 21 runs through the slider 20; the elastic needle assembly 30, the elastic member 40 and the second driving member, at least part of the elastic needle assembly 30 is arranged in the receiving space 21, the elastic member 40 is arranged in the receiving space 21, and the opposite ends of the elastic member 40 can respectively abut against the slider 20 and the elastic needle assembly 30, and the second driving member 50 is used to drive the elastic needle assembly 30 to move along the second direction so that the elastic needle assembly 30 moves close to the workpiece 60 to be processed and squeezes the elastic member 40.

[0031] The first driving member 10 is in transmission connection with the slider 20. As some embodiments of the present application, the first driving member 10 can be configured as a cylinder. The first driving member 10 can drive the slider 20 to move along the first direction close to the workpiece 60 to be processed (mold closing process), and the first driving member 10 can drive the slider 20 to move along the first direction away from the workpiece 60 to be processed (mold opening process). The first direction can be any direction, for example, the first direction can be Figure 1 The X direction is shown.

[0032] The slider 20 has a receiving space 21 , and the receiving space 21 passes through the slider 20 , that is, the receiving space 21 is similar to a through hole.

[0033] At least part of the spring needle assembly 30 is disposed in the accommodation space 21. In some embodiments of the present application, part of the structure of the spring needle assembly 30 is disposed in the accommodation space 21, or the entire structure of the spring needle assembly 30 is disposed in the accommodation space 21. The elastic member 40 has two opposite ends, one end of which can abut against the spring needle assembly 30, and the other end of which can abut against the slider 20, so that the elastic member 40 can be compressed between the spring needle assembly 30 and the slider 20.

[0034] The second driving member is used to drive the spring needle assembly 30 to move along the second direction so that the spring needle assembly 30 moves close to the workpiece 60 to be processed. It can be understood that since the two opposite ends of the elastic member 40 can respectively abut against the spring needle assembly 30 and the slider 20, during the movement of the spring needle assembly 30 close to the workpiece 60 to be processed, the spring needle assembly 30 can squeeze the elastic member 40 to compress the elastic member 40. During the mold opening process, the elastic member 40 can stretch and drive the spring needle assembly 30 to move away from the workpiece 60 to be processed in the second direction. By driving the spring needle assembly 30 to move away from the workpiece 60 to be processed by the elastic member 40, the friction between the spring needle assembly 30 and the workpiece 60 to be processed can be reduced, thereby reducing the probability of tearing the workpiece 60 to be processed.

[0035] As some embodiments of the present application, the spring pin assembly 30 can contact the workpiece 60 to be processed to process a shaft structure.

[0036] As some embodiments of the present application, the first direction and the second direction may be the same direction, or the first direction and the second direction may be different directions.

[0037] Therefore, by providing an elastic member 40 that can be compressed between the elastic needle assembly 30 and the slider 20, the elastic needle assembly 30 can be driven by the elastic member 40 to move away from the workpiece 60 to be processed (mold opening process), thereby reducing the friction between the elastic needle assembly 30 and the workpiece 60 to be processed, and reducing the probability of tearing of the workpiece 60 to be processed, which is beneficial to reducing the product defective rate.

[0038] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the elastic needle assembly 30 includes an elastic needle body 31 and a mounting seat 32. The elastic needle body 31 is disposed on the mounting seat 32. The second driving member is used to drive the mounting seat 32 to move along the second direction.

[0039] As some embodiments of the present application, the elastic needle body 31 and the mounting seat 32 can be integrally formed, that is, the elastic needle body 31 and the mounting seat 32 are constructed as an integrally formed part, and the integrally formed part has good structural strength. By integrally forming the elastic needle body 31 and the mounting seat 32, the connection reliability between the elastic needle body 31 and the mounting seat 32 can be improved, and the probability of breakage at the connection between the elastic needle body 31 and the mounting seat 32 can be reduced.

[0040] As some embodiments of the present application, the spring needle body 31 and the mounting seat 32 can be detachably connected. For example, the spring needle body 31 and the mounting seat 32 can be connected by but not limited to bolt connection, clamping, etc. This arrangement can facilitate the replacement of the spring needle body 31 or the mounting seat 32, and different spring needle bodies 31 or different mounting seats 32 can be replaced to enable the spring needle assembly 30 to adapt to different sliders 20 and different workpieces 60 to be processed, which is conducive to improving versatility.

[0041] The second driving member is used to drive the mounting seat 32 to move along the second direction. This arrangement allows the second driving member to be arranged on a side of the slider 20 away from the workpiece 60 to be processed, which can reduce the difficulty of arranging the second driving member.

[0042] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the slider 20 has a protrusion protruding toward the accommodation space 21 , and both ends of the elastic member 40 can abut against the protrusion and the mounting seat 32 respectively.

[0043] Among them, the protrusion can be constructed as a circular ring structure. By making the slider 20 have a protrusion protruding toward the accommodating space 21, the elastic member 40 can be reliably compressed between the protrusion and the mounting seat 32, so that the elastic member 40 can reliably drive the elastic needle assembly 30 to move along the second direction away from the workpiece 60 to be processed.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the elastic member 40 is sleeved on the elastic pin body 31 .

[0045] Specifically, the elastic member 40 is sleeved on the outside of the elastic needle body 31, that is, the elastic needle body 31 is inserted into the elastic member 40. By sleeved the elastic member 40 on the elastic needle body 31, the elastic needle body 31 can guide the elastic member 40, so that the elastic member 40 can be compressed and stretched in a predetermined direction, which can reduce the probability of the elastic member 40 getting stuck, and is conducive to improving the reliability of the mold device 100.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mold device 100 further includes a limiting member 33 , which is disposed on the slider 20 and located on a side of the mounting seat 32 away from the elastic member 40 . The limiting member 33 is used to abut against the mounting seat 32 to limit the elastic pin assembly 30 .

[0047] It can be understood that the second driving member is used to drive the elastic needle assembly 30 to move in the second direction so that the elastic needle assembly 30 moves close to the workpiece 60 to be processed to compress the elastic member 40. During the mold opening process, the elastic member 40 can stretch and drive the elastic needle assembly 30 to move away from the workpiece 60 to be processed in the second direction. That is to say, the elastic member 40 can stretch and drive the elastic needle assembly 30 to move in the second direction close to the limiting member 33. The limiting member 33 can limit the elastic needle assembly 30. Specifically, the limiting member 33 can limit the mounting seat 32 to reduce the probability of the elastic needle assembly 30 escaping from the accommodating space 21, so as to improve the reliability of the mold device 100.

[0048] In some embodiments of the present invention, along the second direction, a portion of the orthographic projection of the mounting seat 32 overlaps at least a portion of the orthographic projection of the limiting member 33 .

[0049] Specifically, a plane is set, which is perpendicular to the second direction. In other words, the normal of the plane is parallel to the second direction, and the orthographic projection of the mounting seat 32 on the plane at least partially overlaps with the orthographic projection of the limiting member 33 on the plane.

[0050] That is, the orthographic projection of the mounting seat 32 on the plane overlaps with the orthographic projection of the limiting member 33 on the plane, or the orthographic projection of the mounting seat 32 on the plane overlaps with the entire orthographic projection of the limiting member 33 on the plane.

[0051] Such a configuration can ensure that the limiting member 33 and the mounting seat 32 can reliably abut against each other to limit the mounting seat 32, and the limiting member 33 will not completely block the mounting seat 32, thereby facilitating transmission connection between the second driving member and the mounting seat 32, thereby helping to reduce the difficulty of assembling the mold device 100.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mounting seat 32 has a notch 321 , and the limiting member 33 can abut against the side wall of the notch 321 .

[0053] Among them, in certain working states, at least part of the structure of the limiting member 33 can be accommodated in the notch 321, and the limiting member 33 can abut against the side wall of the notch 321 to limit the mounting seat 32. On the one hand, by providing the mounting seat 32 with the notch 321, the volume of the mounting seat 32 can be reduced to save materials. On the other hand, by accommodating at least part of the structure of the limiting member 33 in the notch 321, it is beneficial to reduce the volume of the mold device 100 to achieve a miniaturized design of the mold device 100. In addition, at least part of the structure of the limiting member 33 accommodated in the notch 321 can also guide the mounting seat 32 to a certain extent, so as to reduce the probability of the movement direction of the mounting seat 32 being offset.

[0054] As some embodiments of the present application, the limit member 33 can be made of a flexible material. For example, the limit member 33 can be made of but not limited to rubber or resin. This can reduce the impact force between the mounting seat 32 and the limit member 33, and can reduce the probability of damage to the mounting seat 32 and / or the limit member 33.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first driving member 10 includes: a driving body 11 and a connecting member 12 , the connecting member 12 is fixedly connected to the slider 20 , and the driving body 11 is used to drive the connecting member 12 to move along the first direction.

[0056] Specifically, the connector 12 and the slider 20 can be connected by, but not limited to, bolt connection, clamping, welding, etc., wherein the welding connection has the characteristics of high strength, the connection is relatively strong, but cannot be disassembled; the bolt connection has a simple structure and also has a high strength connection, and the disassembly and replacement of parts are very convenient; the clamping connection realizes mutual connection through the concave and convex structure between the parts, has a high strength connection, and is most convenient for disassembly and installation. The above connection methods can be flexibly applied between the connector 12 and the slider 20 according to actual needs.

[0057] The driving body 11 can drive the connecting member 12 to move along the first direction. The movement of the connecting member 12 along the first direction can drive the slider 20 to move along the first direction, so as to achieve the effect of driving the slider 20 to move closer to or away from the workpiece 60 to be processed along the first direction.

[0058] By connecting the connecting member 12 with the slider 20, the driving body 11 can drive the slider 20 to move by driving the connecting member 12, so as to drive the mold device 100 to switch between the mold opening state and the mold closing state, thereby facilitating the driving of the mold device 100 to move.

[0059] As some embodiments of the present application, during the mold closing process, the slider 20 is first driven to move into place by the first driving member 10, and then the elastic needle assembly 30 is driven by the second driving member to put the elastic member 40 in a compressed state. At this time, the elastic member 40 stores a certain amount of mechanical energy to provide a buffer for the subsequent mold opening; during the mold opening process, the second driving member is separated from the elastic needle assembly 30, at which time the elastic member 40 releases mechanical energy, driving the elastic needle body 31 to move along the second direction away from the workpiece 60 to be processed, so that the elastic needle body 31 is separated from the workpiece 60 to be processed, and then the first driving member 10 drives the slider 20 to move along the first direction to complete the mold opening process.

[0060] In some embodiments of the present invention, Figure 3 As shown, the mold device 100 further includes an insert 50 , at least a portion of which is disposed in the accommodating space 21 and fixedly connected to the slider 20 , and the insert 50 is suitable for contacting a workpiece 60 to be processed.

[0061] Among them, part of the structure of the insert 50 is arranged in the accommodating space 21 or the entire structure of the insert 50 is arranged in the accommodating space 21, the insert 50 and the slider 20 can be connected by but not limited to bolt connection, clamping, etc., and the insert 50 can contact the workpiece 60 to be processed. As some embodiments of the present application, the insert 50 can process a weakened groove on the workpiece 60 to be processed.

[0062] As some embodiments of the present application, the insert 50 is detachably connected to the slider 20. It is understandable that since the mold device 100 needs to frequently close and open the mold, the part in contact with the workpiece 60 to be processed is usually worn out. By making the insert 50 detachably connected to the slider 20, the worn insert 50 can be replaced separately, which can achieve the continuous use of the mold device 100 and greatly reduce the manufacturing cost of the mold device 100. In addition, by making the insert 50 detachably connected to the slider 20, different inserts 50 can be replaced to meet the needs of different workpieces 60 to be processed, so that the mold device 100 can be adapted to different types of workpieces 60 to be processed, so as to improve the versatility of the mold device 100.

[0063] In some embodiments of the present invention, Figure 3 As shown, the mold device 100 further includes an insert 50 , at least a portion of which is disposed in the accommodating space 21 and is fixedly connected to the spring pin assembly 30 .

[0064] Part of the structure of the insert 50 is disposed in the accommodating space 21 or the entire structure of the insert 50 is disposed in the accommodating space 21 , and the insert 50 and the spring pin assembly 30 may be connected by, but not limited to, bolt connection, clamping, and the like.

[0065] In this way, when the elastic member 40 stretches and drives the elastic needle assembly 30 to move along the second direction away from the workpiece 60, the elastic needle assembly 30 can drive the insert 50 to move together, thereby reducing the friction between the insert 50 and the workpiece 60, thereby further reducing the probability of tearing the workpiece 60, which is beneficial to further reduce the product defect rate.
