In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1 As shown, the utility model discloses a machine tool die base, comprising an upper die base 1, a lower die base 2 and a plurality of guide pillars 3, the upper die base 1 is used to be fixedly connected to a driving device on the machine tool, and the lower die base 2 is used to be fixedly connected to a workbench on the machine tool; the driving device can drive the upper die base 1 to reciprocate along the vertical direction, and in some embodiments, the driving device can be a slide rail slider mechanism, and the upper die base 1 is fixedly connected to the slider; one end of the guide pillar 3 is connected to the lower die base 2, and the other end is penetrated through the upper die base 1 and is used to guide the upper die base 1 to move up and down; a die installation space 4 is provided between the upper die base 1 and the lower die base 2; a first elastic component 11 is provided on the upper die base 1, and the first elastic component 11 is used to stop with the upper die of the die, and a second elastic component 21 is provided on the lower die base 2, and the second elastic component 21 is used to stop with the lower die of the die. It can be understood that the installation space 4 between the upper die base 1 and the lower die base 2, on the one hand, sets restrictions on the size of the mold and provides a standard for the design of the mold, and on the other hand, can provide an installation reference for the mold, so that the mold can be simply and quickly installed on the machine tool for use, thereby improving the work efficiency of designers and operators; the setting of the first elastic component 11 and the second elastic component 21 allows most of the spring arrangement that provides unloading force to the mold in the design of the mold to be transferred to the die base, which can make the mold lightweight and thus reduce the manufacturing cost of the mold.

[0042] In some embodiments, Figure 2As shown, the upper mold base 1 is provided with a plurality of first mounting holes 12; the first elastic component 11 includes a first elastic member 111, a top plate 112, and a first top block 113; wherein the first elastic member 111 is installed in the first mounting hole 12, the top plate 112 is connected to one end of the first elastic member 111, and is fixedly connected to the upper mold base 1; the first top block 113 is connected to the other end of the first elastic member 111, and can move up and down in the first mounting hole 12, and the end of the first top block 113 away from the first elastic member 111 can stop at the upper mold of the mold. It can be understood that the top plate 112 is arranged at the top end of the upper mold base 1, the first top block 113 is arranged in the first mounting hole 12 at the bottom end of the upper mold base 1, and the first elastic member 111 is arranged between the top plate 112 and the first top block 113. In some specific embodiments, in order to simplify the structure and optimize the installation process, multiple first mounting holes 12 can correspond to one top plate 112, the top plate 112 blocks one end of the first mounting hole 12, the other end of the first mounting hole 12 is provided with a flange along the inner circumferential surface, and the first top block 113 is provided as a cylinder with steps, so as to prevent the first top block 113 from falling out before the mold is installed. In other embodiments, a plurality of guide grooves are provided in the first mounting hole 12, and a guide block is provided on the first top block 113. The guide groove is open at one end close to the top plate 112 to install the first top block 113, and the guide groove is closed at one end away from the top plate 112. The guide groove and the guide block can cooperate to limit the first top block 113 from being separated from the first mounting hole 12. It can be understood that the first top block 113 can abut against the mold, so that the first elastic component 11 replaces the corresponding structure in the original mold to provide the unloading force.

[0043] In some embodiments, Figure 3As shown, the lower die base 2 is provided with a plurality of second mounting holes 22; the second elastic component 21 includes a second elastic member 211, a screw plug 212, and a second top block 213. The second elastic member 211 is installed in the second mounting hole 22, the screw plug 212 is connected to one end of the second elastic member 211, and is threadedly connected to the second mounting hole 22; the second top block 213 is connected to the other end of the second elastic member 211, and can move up and down in the second mounting hole 22, and the end of the second top block 213 away from the second elastic member 211 stops at the lower die. It can be understood that the screw plug 212 and the second elastic member 211 can be abutted or fixedly connected. The screw plug 212 blocks the bottom end of the second mounting hole 22, the top end of the second mounting hole 22 is provided with a flange along the inner circumferential surface, and the second top block 213 is provided as a cylinder with steps, so as to prevent the second top block 213 from popping out before the mold is installed. In other embodiments, a plurality of guide grooves are provided in the second mounting hole 22, and a guide block is provided on the first top block 113. The guide groove is open at one end close to the screw plug 212 to install the second top block 213, and the guide groove is closed at one end away from the screw plug 212. The guide groove and the guide block can cooperate to prevent the first top block 113 from being separated from the first mounting hole 12. It can be understood that the second top block 213 can abut against the mold, so that the second elastic component 21 replaces the elastic member provided in the original mold to provide the unloading force. It should be noted that the second elastic component 21 on the lower mold base 2 can meet the flexibility of the position setting of the lower mold and the upper mold when the mold is designed, and on the other hand, it can also meet the requirements of some special mold designs. In order to adapt to more complex molding requirements, both the lower mold and the upper mold need to be designed to be movable. At this time, the elastic components that provide the unloading force in the two movable molds of this type of mold can be externalized to reduce the weight of the mold, realize the lightweight of the mold, and reduce the manufacturing cost of the mold.

[0044] In some embodiments, Figure 2 and Figure 3 As shown, the lower die base 2 is also provided with a first positioning mechanism 23, which is used to fix the lower die to the lower die base 2, and the upper die base 1 is provided with a second positioning mechanism 14, which is used to fix the upper die to the upper die base 1. Fig. 9 As shown, the first positioning mechanism 23 includes a first positioning member 231, a first locking member 232, a second positioning member 233, and a second locking member 234, wherein the first positioning member 231 is arranged at one end of the lower mold base 2 in the length direction, and the first locking member 232 is arranged at the other end of the lower mold base 2 in the length direction and is arranged opposite to the first positioning member 231; the second positioning member 233 is arranged on one side of the first positioning member 231 and the first locking member 232, and the second locking member 234 is arranged opposite to the second positioning member 233; the first positioning member 231 and the first locking member 232 are used to fix the position of the lower mold in the length direction of the lower mold base 2, and the second positioning member 233 and the second locking member 234 are used to fix the position of the lower mold in the width direction of the lower mold base 2.

[0045] In some specific embodiments, a through slot 24 is provided on the lower die base 2 along the length direction, and the first positioning mechanism 23 is arranged in the through slot 24. Figure 4 and Figure 5 As shown, the first positioning member 231 is arranged at one end of the through slot 24, the first locking member 232 is arranged at the other end of the through slot 24 and is arranged opposite to the first positioning member 231, the second positioning member 233 is arranged on one side of the first positioning member 231 and the first locking member 232, and the second locking member 234 is arranged on the side opposite to the second positioning member 233; the first positioning member 231 and the first locking member 232 are used to fix the position of the lower mold in the length direction of the through slot 24, and the second locking member 234 and the second positioning member 233 are used to fix the position of the lower mold in the width direction of the through slot 24. A plurality of positioning slots 13 are provided on the upper mold base 1, and a second positioning mechanism 14 is arranged in the positioning slot 13, and the position of the second positioning mechanism 14 in the positioning slot 13 is adjustable. In some embodiments, the second positioning member 233 can be the side wall of the through slot 24, and the second locking member 234 cooperates with the side wall of the through slot 24 to fix the position of the lower mold in the width direction of the through slot 24. It can be understood that, by setting the first positioning mechanism 23 and the second positioning mechanism 14, the mold can be quickly installed in the installation space 4 between the upper mold base 1 and the lower mold base 2 and fixed, so as to achieve rapid positioning and operation and improve the operation efficiency. In other embodiments, a groove is provided on the lower mold base 2 along the length direction, the first positioning mechanism 23 is arranged in the groove, the first positioning member 231 can be a side wall in the length direction of the groove, and the second positioning member 233 can be a side wall in the width direction of the groove.

[0046] Specifically, when installing the mold, the lower mold of the mold is tightly abutted against the side wall of the second positioning member 233 and one side of the first positioning member 231, and then the first locking member 232 is operated to lock the mold in the length direction of the through slot 24, and then the second locking member 234 is adjusted to lock the mold in the width direction of the through slot 24. At this point, the lower mold of the mold is positioned on the lower mold base 2. In order to ensure that the lower mold does not move in the vertical direction, a plurality of T-slots are also provided on the lower mold base 2, and a hydraulic caliper is provided in each T-slot, which can clamp the lower mold to prevent the lower mold from moving or shaking in the vertical direction.

[0047] In some embodiments, the first positioning member 231 is provided with at least one, in some specific embodiments, such as Figure 4As shown, two first positioning members 231 are provided, and are arranged at intervals in the width direction of the through slot 24. The first positioning member 231 includes a first positioning plate 2311 and a first adjusting plate 2312, wherein the first positioning plate 2311 is arranged in the through slot 24, and the first adjusting plate 2312 is arranged on the lower die base 2 and located outside the through slot 24, and can be connected with the first positioning plate 2311 in an adjustable position. More specifically, a plurality of threaded holes are provided on the first adjusting plate 2312, and threaded holes are also provided on the lower die base 2 and the first positioning plate 2311 corresponding to the threaded holes of the first adjusting plate 2312. Some of the threaded holes of the first adjusting plate 2312 are used to fix the first adjusting plate 2312 with the lower die base 2 through fixing bolts 2313, and some of the threaded holes are used to adjust the position of the first adjusting plate 2312 with the first positioning plate 2311 through adjusting bolts. By screwing the adjusting bolts, the position of the first positioning plate 2311 in the through slot 24 along the length direction can be adjusted. In order to ensure the stability of the position of the first positioning plate 2311 after adjustment, Figure 6 and Figure 7 As shown, a first through hole 23111 is formed on the first positioning plate 2311, a countersunk hole 23112 is provided at one end of the first through hole 23111, and the first positioning plate 2311 is movably connected to the lower die base 2 via a fixing bolt 2313. More specifically, the diameter of the first through hole 23111 is slightly larger than the diameter of the column of the fixing bolt 2313, and the diameter of the countersunk hole 23112 is slightly larger than the diameter of the cap of the fixing bolt 2313, so that the position of the first positioning plate 2311 in the through slot 24 along the length direction can be finely adjusted.

[0048] In other embodiments, the first through hole 23111 and the countersunk hole 23112 can be set as waist holes opened along the length direction of the through slot 24. At this time, the width of the first through hole 23111 can be equal to the diameter of the column of the fixing bolt 2313, and the length of the first through hole 23111 is the adjustable stroke of the first positioning plate 2311 in the through slot 24. The stroke length can be set according to actual needs and is not specifically limited here. Similarly, the width of the countersunk hole 23112 can be equal to the diameter of the cap body of the fixing bolt 2313, and the length of the countersunk hole 23112 matches the length of the first through hole 23111. It can be understood that when the position of the first positioning member 231 needs to be adjusted, it is generally in the installation, positioning and debugging stage of the new mold. First, loosen the fixing bolt 2313 that fixes the first positioning plate 2311 to the lower mold base 2, and then turn the adjusting bolt to drive the first positioning plate 2311 to move to the outside of the lower mold base 2, and then place the mold. After the placement is completed, ensure that the first positioning member 231 and the first locking member 232 can complete the locking along the length direction of the through groove 24. After that, when the first locking member 232 is in a locked state, tighten the adjusting bolt to make the first positioning plate 2311 tightly abut the mold, and finally tighten the fixing bolt 2313 that fixes the first positioning plate 2311 to the lower mold base 2. When this type of mold is used later, the first positioning member 231 does not need to be adjusted again and can be directly used as a positioning reference.

[0049] In some embodiments, Figure 5 As shown, the first locking member 232 includes an eccentric wrench 2321 and a handle 2322 disposed on the eccentric wrench 2321. One end of the eccentric wrench 2321 is rotatably disposed on the lower die base 2, and the side of the other end is provided with the handle 2322. The eccentric wrench 2321 is rotated to abut against the lower die to achieve locking by adjusting the handle 2322. It can be understood that the combination of the eccentric wrench 2321 and the handle 2322 has the advantages of simple structure and convenient use.

[0050] In some embodiments, at least one first locking member 232 is provided. In some specific embodiments, two first locking members 232 are provided, and the two first locking members 232 are spaced apart in the width direction of the through slot 24. It can be understood that providing two or more first locking members 232 can ensure that the lower mold is locked more stably.

[0051] In some embodiments, Figure 8 and Fig. 9As shown, the second locking member 234 includes a second positioning plate 2341, a second adjustment plate 2342 and a cover plate 2343. A groove is provided on the lower die base 2, one end of the groove is connected to the through groove 24, and the other end is provided with a second adjustment plate 2342, and the second adjustment plate 2342 is fixedly connected to the lower die base 2 by bolts; the second positioning plate 2341 is arranged in the groove, and an elastic member is also arranged between the second positioning plate 2341 and the second adjustment plate 2342, which can provide a locking force, and the compression amount of the elastic member can be adjusted by adjusting the distance between the second adjustment plate 2342 and the lower die base 2, thereby adjusting the magnitude of the locking force. In order to ensure the stability of the position of the second positioning plate 2341, as Fig.10 As shown, the second positioning plate 2341 is provided with a second through hole 23411, and a hole is also provided on the lower mold base 2 corresponding to the second through hole 23411 of the second positioning plate 2341. A positioning pin 2344 is passed through the second through hole 23411 and the corresponding hole on the lower mold base 2 to movably connect the second positioning plate 2341 and the lower mold base 2. Specifically, the diameter of the second through hole 23411 on the second positioning plate 2341 is larger than the diameter of the positioning pin 2344, and the diameter of the hole in the lower mold base 2 is equal to the diameter of the positioning pin 2344. The cover plate 2343 is covered on the second positioning plate 2341 and is detachably connected to the lower mold base 2 to prevent the positioning pin 2344 from falling out. It can be understood that when installing the lower mold, the second adjustment plate 2342 is separated from the lower mold base 2, so that the end of the second positioning plate 2341 close to the through slot 24 can be retracted into the groove to prevent interference with the lower mold. After the lower mold is installed, the second adjustment plate 2342 is adjusted to be close to the lower mold base 2 and fixed. The second adjustment plate 2342 compresses the elastic part to make the second positioning plate 2341 abut against the lower mold and apply a locking force.

[0052] In some specific embodiments, a plurality of holes are provided at one end of the second positioning plate 2341 close to the second adjustment plate 2342, and an elastic member, such as a spring, is provided in each hole, one end of the spring abuts against the bottom of the groove, and the other end abuts against the second adjustment plate 2342. It can be understood that providing a plurality of holes to accommodate the elastic members can keep the elastic force direction of the elastic members always perpendicular to the length direction of the through slot 24.

[0053] In some embodiments, Figure 2As shown, the second positioning mechanism 14 includes a second positioning member 141, which is arranged on the upper die holder 1 and can fix the upper die of the die. In some specific embodiments, the second positioning member 141 is set as a hydraulic caliper, and the positioning groove 13 is set as a T-slot. The hydraulic caliper is set in the T-slot and the position is adjustable, which can clamp the upper die of the die to fix the upper die on the upper die holder 1. It can be understood that through the arrangement of the first positioning mechanism 23 and the second positioning mechanism 14, an installation reference of the die on the machine tool is provided, so that the installation process of the die on the machine tool is standardized, and the die can be quickly and accurately installed in the installation space 4 without having to re-set the die and realign it each time, thereby improving the working efficiency.

[0054] In some embodiments, Figure 5 and Figure 8 As shown, the die base of the machine tool further includes a connection component 15, which can selectively install the functional module for processing the workpiece; in some specific embodiments, the connection component 15 includes a fixing device 151 and a locking device 152, and the fixing device 151 can fix the functional module to the upper die base 1 and be locked by the locking device 152. The fixing device 151 includes a first fixing member 1511 and a second fixing member 1512, the first fixing member 1511 is arranged at the bottom of the upper die base 1, the first fixing member 1511 extends along the width direction of the upper die base 1, and two first fixing members 1511 are arranged at intervals along the length direction of the upper die base 1; the second fixing member 1512 is arranged at the bottom of the upper die base 1, the second fixing member 1512 extends along the width direction of the upper die base 1, and two second fixing members 1512 are arranged at intervals along the length direction of the upper die base 1; the second fixing member 1512 and the first fixing member 1511 are arranged at intervals along the width direction of the upper die base 1, and are respectively engaged with different parts of the functional module and fixed by bolts. It can be understood that the interval between the two first fixing members 1511 and the interval between the two second fixing members 1512 can be the same or different, depending on the width of the contact parts between the two and the functional module; the heights at which the first fixing members 1511 and the second fixing members 1512 are set on the upper mold base can be the same or different, depending on the positions of the contact parts between the two and the functional module.

[0055] The locking device 152 is arranged on the upper die base 1 and away from the side of the second fixing member 1512. The locking device 152 can lock the functional module to prevent the functional module from shaking on the upper die base 1. It is understandable that the functional module can be any one of a stamping module, a drilling module, a tapping module, etc. Taking the existing in-mold automatic tapping mold structure as an example and comparing it with the utility model, the tapping module is no longer installed and configured with the mold by connecting the connecting component 15 with the tapping module, so that multiple molds can share a set of tapping modules, which is different from the in-mold tapping mold structure on the market, which is a one-mold-one-tapping structure, reducing the manufacturing cost, circulation cost, and labor cost of the mold, and reducing the cost of parts processing.

[0056] To adapt to the height of the machine tool and prevent the functional module from interfering with the machine tool slide, such as Figure 1 and Figure 2 As shown, the machine tool die base disclosed in the utility model also includes a height matching block 5, which is arranged above the upper die base 1, and a die handle mounting hole is arranged at the axial symmetry center of the height matching block 5, and the die handle mounting hole is installed in cooperation with the die handle on the upper die base 1. The height matching block 5 can not only adjust the height of the machine tool die base to ensure that the machine tool die base and the installed die can correctly cooperate with the machine tool worktable during the stamping process, thereby realizing precise stamping operation, but also can adapt to the closing height and slider stroke of the machine tool, thereby preventing the components of the functional module from colliding with the slider of the machine tool.

[0057] In some embodiments, Fig.12 As shown, the upper die base 1 is also provided with a slide groove, and the locking device 152 includes an inclined wedge assembly 1521, and the inclined wedge assembly 1521 includes a locking block 15211, a slide rod 15213, and a reset member 15214. The locking block 15211 is slidably arranged in the slide groove, and a reset member 15214 is arranged at one end of the locking block 15211 and the slide groove, and an inclined wedge groove 152111 is arranged on the locking block 15211, and the slide rod 15213 is slidably arranged on the upper die base 1 and an inclined wedge surface 152131 is arranged at one end; wherein, as Fig.13As shown, a groove is opened along the width direction of the locking block 15211, and then at least part of the side wall on one side of the groove is set as an inclined surface, thereby forming an inclined wedge groove 152111, the width of the inclined wedge groove 152111 is greater than the width of the sliding rod 15213, and the shape of the inclined wedge surface 152131 set on one side of the sliding rod 15213 matches the side of the groove of the locking block where the inclined surface is set. The pull rod 15212 can pull the sliding rod 15213 to move, thereby driving the locking block 15211 to move, and cooperate with the reset member 15214 to realize the locking and unlocking of the locking device 152. Since the locking block 15211 is set in the sliding groove, in order to enable the sliding rod 15213 to cooperate with the locking block 15211, the sliding rod 15213 can also be embedded in the upper mold base 1, and then an anti-slip plate 18 is set on the upper mold base 1 above the sliding rod 15213 and the locking block 15211 to prevent the sliding rod 15213 and the locking block 15211 from escaping from the groove. In some specific embodiments, the wedge assembly 1521 also includes a pull rod 15212 and a support block 15215. The pull rod 15212 is rotatably set on the upper mold base 1. The pull rod 15212 is movably connected to one end of the sliding rod 15213 away from the locking block 15211. A pull rod handle is also provided on the end of the pull rod 15212 away from the sliding rod 15213 to make the operation of the pull rod 15212 more convenient. The pull rod 15212 is rotatably set on the upper mold base 1 through the support block 15215. Specifically, the support block 15215 is fixedly set on the upper mold base 1, and the pull rod 15212 is rotatably connected to the support block 15215 through a pin. When unlocking the functional module, the operator pulls the pull rod handle to drive the pull rod 15212 to rotate around the pin. The other end of the pull rod 15212 is movably connected to the slide bar 15213, which can drive the slide bar 15213 to move. The inclined wedge surface 152131 of the slide bar 15213 enters the inclined wedge groove 152111 of the locking block 15211, driving the locking block 15211 to overcome the reset force of the reset member 15214 and move into the slide groove to unlock the functional module. The initial state of the locking block 15211 is the locked state. When installing the functional module, the end of the locking block 15211 away from the reset member 15214, that is, the end that plays a locking role, is provided with an inclined surface, which can facilitate the locking block 15211 to be pressed into the slide groove when the functional module is assembled, so that it can be installed in place. After being installed in place, the locking block 15211 restores the locked state under the action of the reset member 15214, wherein the reset member 15214 can be a spring. It can be understood that the movable connection between the slide rod 15213 and the pull rod 15212, that is, the slide rod 15213 can simultaneously rotate and move horizontally relative to the pull rod 15212, prevents directional interference between the two when they move. The specific setting of the movable connection is a conventional setting in this field and will not be repeated here. The wedge assembly 1521 can change the direction of the original force and reduce the overall space occupied by the mold base. In this embodiment, the lever principle is used to have a force-enhancing effect, making the operation more labor-saving.

[0058] In other embodiments, the locking device 152 can also be set as other mechanisms that can drive the locking block 15211, such as opening a waist hole inclined along the length direction of the locking block 15211 on the locking block 15211, and a cylindrical boss is provided at one end of the sliding rod 15213 that cooperates with the locking block 15211, and the cylindrical boss cooperates with the inclined waist hole on the locking block 15211. The locking block 15211 can be driven to be locked and unlocked only by moving the sliding rod 15213.

[0059] In some embodiments, a plurality of weight-reducing holes and / or weight-reducing grooves are provided on the upper die base 1 and the lower die base 2 to reduce the overall weight of the die base; in addition, a suction funnel is provided at the installation position of the corresponding functional module on the lower die base 2, which can collect processing debris of the workpiece and flow out of it for easy cleaning.

[0060] In some embodiments, a die handle 17 is fixedly provided at the center of the upper die base 1. When the upper die base 1 is installed, the die handle 17 cooperates with the die handle positioning hole on the machine tool to quickly locate the pressure center, and is fixed to the slider of the machine tool by four screws, wherein the screws are M20 hexagon socket screws. When the lower die base 2 is installed, it is also fixed to the machine tool worktable by four screws, and corresponding mounting holes are provided on the upper die base 1, the lower die base 2 and the height matching block 5.

[0061] In some embodiments, Fig.14 As shown, the machine tool die base disclosed in the utility model also includes a third elastic component 16, which can give the functional module an initial downward pressure to process the workpiece to be processed. The third elastic component 16 is arranged below the die handle 17, and includes a sleeve 161, a third elastic member 162 and a third top block 163. The sleeve 161 is fixed to the upper die base 1, and the third elastic member 162 is arranged in the sleeve 161 and is located between the upper die base 1 and the third top block 163. The third top block 163 can move in the sleeve 161 and has a certain stroke. It can be understood that the sleeve 161 can regulate the direction of compression and extension of the third elastic member 162, and the third top block 163 is movably arranged in the sleeve 161 through the third elastic member 162. A structure that limits the stroke of the third top block 163 is provided in the sleeve 161 to prevent the third top block 163 from slipping out of the sleeve 161. The provision of the third elastic component 16 can provide the functional module with a buffering effect, prevent the tool from being damaged due to pressure overload during stamping, and can also simplify the structure of the functional module and reduce the manufacturing cost of the functional module. In some specific embodiments, a plurality of mounting grooves are provided on the side of the third top block 163, and a guide wheel is rotatably provided in each mounting groove. The guide wheel can roll in contact with the inner wall of the sleeve 161, thereby reducing the friction between the sleeve 161 and the third top block 163, so that the third top block 163 can move better in the sleeve 161.

[0062] The utility model also discloses a machine tool, comprising a driving device and a workbench. The machine tool uses the above-mentioned machine tool die base, wherein the upper die base 1 is fixedly connected to the driving device, and the lower die base 2 is fixedly connected to the workbench.

[0063] The installation process of the machine tool die base disclosed in the utility model is as follows: first, place the machine tool die base on the machine tool work surface, quickly locate the pressure center through the die handle 17 and the die handle positioning hole on the slide of the machine tool, penetrate the installation hole through the screw, and preliminarily fix it with the work surface of the machine tool, that is, pre-lock the position of the lower die base 2, then place the height matching block 5 on the die base, lock the position of the upper die base 1, and finally lock the position of the lower die base 2 to complete the installation of the machine tool die base, and the operation process is simple.

[0064] In order to more intuitively describe the working process of the machine tool die base of the utility model during machine tool processing, the following parts of the mold closely related to the machine tool die base are briefly described, such as Fig.15 and Fig.16 As shown, the upper mold of the mold includes a fixed plate 200 and a stripping plate 100, and the fixed plate 200 and the stripping plate 100 are connected by a stripping screw 300. Specifically, one end of the stripping screw 300 is threadedly connected to the stripping plate 100, and the other end is movably connected in a limiting hole of the fixed plate 200. The length of the limiting hole is the stroke length between the stripping plate 100 and the fixed plate 200. The stripping screw 300 movably connects the fixed plate 200 and the stripping plate 100 through the limiting hole.

[0065] When the machine tool processes the workpiece, the mold is installed in the installation space 4 between the upper mold base 1 and the lower mold base 2, the upper mold is fixedly connected to the upper mold base 1, and the lower mold is fixedly connected to the lower mold base 2. The first elastic component 11 corresponds to the unloading screw 300 of the upper mold. During the mold closing stroke (i.e., the machine tool slider moves from top to bottom), the machine tool slider drives the upper mold base 1 and the upper mold to move downward to perform operations such as stamping on the workpiece to be processed. At this time, the bottom of the unloading plate 100 first contacts the lower mold and the workpiece to be processed. After the complete contact, the unloading plate 100 no longer moves, and the fixed plate 200 continues to press down with the upper mold base 1. At this time, the unloading screw 300 presses the first elastic component 11 until the stroke ends. During the demolding stroke (i.e., the machine tool slider moves from bottom to top), the machine tool slider drives the upper die base 1 to move upward. At this time, the punch head and other functional modules move upward with the upper die base 1 to withdraw the workpiece to be processed. The unloading screw 300 also applies force to the unloading plate 100 under the elastic force of the first elastic component 11, so that the unloading plate 100 continues to press down the workpiece to be processed until the unloading screw 300 reaches the bottom surface of the limiting hole. The first elastic component 11 no longer applies elastic force to the unloading screw 300. At the same time, the fixed plate 200 begins to apply an upward pulling force to the unloading screw 300, pulling the unloading screw 300 and the unloading plate 100 upward to separate from the processed workpiece until the stroke ends, completing the demolding process. When the lower die of the mold needs to be unloaded or when both the upper die and the lower die in a specially designed mold need to be movable for unloading, the lower die includes a unloading plate 100 and a fixed plate 200 (not shown in the figure), and the unloading plate 100 of the lower die is connected to the fixed plate 200 of the lower die through the unloading screws 300 of the lower die, and the fixed plate 200 of the lower die is fixedly connected to the lower die base 2, and the unloading plate 100 of the lower die is arranged above the fixed plate 200 of the lower die. The unloading plate 100 of the lower die and the fixed plate 200 of the lower die are contacted with the second elastic component 21 through the inner guide column spring or directly by the unloading screws 300, and the second elastic component 21 provides elastic force to support the unloading plate 100 of the lower die so that the two maintain a distance. In the mold closing stroke, the stripper plate 100 of the lower mold moves downward under the pressure of the stripper plate 100 of the upper mold, and the stripper plate 100 of the lower mold drives the stripper screw 300 of the lower mold to press down the second elastic component 21 until the stripper plate 100 of the lower mold presses against the fixed plate 200 of the lower mold, and the mold closing stroke ends; in the mold withdrawal stroke, the slide block of the machine tool drives the upper mold to move upward, and the pressure applied to the stripper plate 100 of the lower mold gradually decreases, and the stripper plate 100 of the lower mold gradually moves upward under the elastic force applied by the second elastic component 21 to the stripper screw 300 of the lower mold until it returns to its original state, completing the mold withdrawal process. It can be understood that the above working process is only a rough description of the movement process of the main components of the mold that cooperates with the machine tool mold base when it is working, and the purpose is to facilitate the understanding of the working principle of the machine tool mold base components, without limiting the specific structure of the mold.

[0066] The machine tool die base disclosed in the utility model includes an upper die base, a lower die base and a plurality of guide pillars, and a mold installation space is provided between the upper die base and the lower die base; a first elastic component is provided on the upper die base, and the first elastic component is used to stop with the upper die of the mold; a second elastic component is provided on the lower die base, and the second elastic component is used to stop with the lower die of the mold, providing an installation space and a reference for the mold on the machine tool, reducing the drawing time and design errors of the designer, and reducing the cost of mold rework. At the same time, in the design of the mold, the spring arrangement that provides the unloading force for the mold can be transferred to the machine tool die base, so that the mold can be lightweight, and the manufacturing cost of the mold can be reduced. The machine tool using the above-mentioned machine tool die base disclosed in the utility model standardizes the process of installing and making the mold, is easy to use, and improves the work efficiency of the operator.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
