[0032] Embodiments of the present application 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] In the description of the present application, it should be understood that the terms "length", "width", "upper", "lower", "upward", "vertical", "horizontal", "bottom", "inside", "outside", "inner side", "outer side" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] The storage limiter in the stamping equipment includes a detection component and a sensing component. The detection component has a detection end. Under normal working conditions (or stamping conditions), the sensing component is blocked at the detection end so that the detection component can detect the sensing component. Under shutdown conditions, the sensing component needs to avoid the detection end so that the detection end cannot detect the sensing component. Different signals are output through the position of the sensing component relative to the detection end, and the start and stop of the stamping are controlled through the control center of the stamping equipment.

[0037] In the related technology, the sensing component can be flipped relative to the detection component at the front side of the detection end, so that the sensing component moves along the sensing direction towards or away from the detection end of the detection component. When the stamping equipment is performing stamping vibration, the vibration causes the sensing component to flip relative to the detection component, and the sensing component will flip and move away from the detection end. When the vibration is too large, the flipping angle of the sensing component increases, so that the sensing component flips and leaves the detection range of the detection end. The detection signal sent by the detection end along the sensing direction cannot reach the sensing component, and the storage limit switch will have a signal loss problem, and the vibration will cause the stamping equipment to shut down abnormally.

[0038] In order to reduce the problem of unexpected shutdown caused by vibration, the present application provides a stamping die assembly, wherein the sensing component is moved from the side to the detection end of the detection component, the sensing component cannot be flipped in front of the detection end, and the sensing component cannot be away from the detection end along the sensing direction, so that the sensing component can always maintain an initial spacing distance from the detection end, ensuring that the sensing component and the detection end always maintain a relatively stable positional relationship in the sensing direction, thereby ensuring the stability of the detection signal.

[0039] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] See also Figure 1-4 As shown, Figure 1 A schematic structural diagram of a stamping die assembly provided in an embodiment of the present application is shown; Figure 2 A schematic diagram showing a state of a sensing component 3 in a stamping die assembly provided in an embodiment of the present application in a non-sensing position; Figure 3 A schematic diagram showing a state of a sensing component 3 in a stamping die assembly provided by an embodiment of the present application in another non-sensing position after flipping; Figure 4 A schematic diagram of the state of a sensing component 3 in a sensing position in a stamping die assembly provided by an embodiment of the present application is shown; an embodiment of the present application provides a stamping die assembly, the stamping die assembly includes a first die base 1 and a second die base 2 arranged relatively to each other, the stamping die assembly also includes a storage limiter, the storage limiter includes a detection component 4 and a sensing component 3; the detection component 4 has a sensing direction Y, and the detection component 4 is installed on the second die base 2; the sensing component 3 is movably installed on the second die base 2, and the sensing component 3 can move in a movable plane perpendicular to the sensing direction Y, so that the sensing component 3 can switch between a sensing position relative to the detection component 4 and a non-sensing position avoiding the detection component 4.

[0041] It should be noted that the vibration direction Z of the stamping equipment is along the direction in which the first die base 1 and the second die base 2 are relatively arranged. For example, the second die base 2 is located below the first die base 1, and the vibration direction Z is along the vertical direction.

[0042] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the stamping die assembly, thereby obtaining product parts with certain shapes, sizes and performances. The stamping die assembly generally has two die bases, one for stamping movement and the other for fixed die base. By moving the moving die base toward the fixed die base for extrusion, a formed stamping part can be formed.

[0043] The two die bases in the present stamping die assembly are respectively a first die base 1 and a second die base 2, wherein, when the first die base 1 is a die base capable of stamping movement, the second die base 2 is a fixed die base, and optionally, when the second die base 2 is a die base capable of stamping movement, the first die base 1 is a fixed die base.

[0044] The storage limiter is a safety component that can be used to detect the relative position relationship between the first die base 1 and the second die base 2 to control the operation or shutdown of the stamping equipment.

[0045] Specifically, before the stamping equipment is put into production, it is necessary to adjust the position of the sensing component 3 for storing the limit switch so that the sensing component 3 is adjusted to the sensing position. After the detection component 4 senses the signal, it transmits the signal to the control center of the stamping equipment. The control center controls the relative movement between the first die base 1 and the second die base 2 so that the stamping equipment performs the stamping action. The movement of the sensing component 3 can be controlled manually or mechanically. When the sensing component 3 is away from the sensing position, or it can also be understood that when the sensing component 3 is in the non-sensing position, the stamping equipment cannot perform stamping work, or the stamping equipment will switch from a working state to a shutdown state.

[0046] In this stamping die assembly, the detection component 4 is used to detect the position of the sensing component 3. The detection component 4 has a sensing direction Y, which is the output direction of the signal when the detection component 4 detects. For example, the detection component 4 uses a sensor, and the sensor emits a detection signal. The output direction of the detection signal is the sensing direction Y of the sensor.

[0047] The sensor includes sensitive elements, conversion elements, conversion circuits and auxiliary power supplies. The sensitive elements directly sense the measured quantity and output physical quantity signals that have a definite relationship with the measured quantity. The conversion elements convert the physical quantity signals output by the sensitive elements into electrical signals. The conversion circuit is responsible for amplifying and modulating the electrical signals output by the conversion elements. The conversion elements and conversion circuits generally also require auxiliary power supplies.

[0048] In this example, the sensitive element in the detection component 4 is used to detect whether the sensing component 3 is in the sensing position, for example, in combination with Figure 6As shown, the sensor has a detection end 42, and the detection end 42 emits a detection signal. When the sensing component 3 is in the sensing position, that is, the sensing component 3 is opposite to the detection end 42 of the sensor, the sensor can receive a feedback signal, and the sensitive element outputs a physical quantity signal, which is finally fed back to the control center of the stamping equipment in the form of an electrical signal. When the detection component 4 detects that the sensing component 3 is in the sensing position, the stamping equipment can control the stamping die assembly to perform stamping work; when the sensing component 3 is not in the sensing position, that is, the sensing component 3 is in the non-sensing position, that is, the sensing component 3 avoids the detection end 42 of the sensor, and the sensor cannot receive a feedback signal, the sensitive element outputs a physical quantity signal, which is finally fed back to the control center of the stamping equipment in the form of an electrical signal. When the detection component 4 cannot detect the sensing component 3, the stamping equipment can control the stamping die assembly to prohibit stamping work.

[0049] The sensing component 3 is movably mounted on the second mold base 2. When the sensing component 3 moves relative to the second mold base 2, the sensing component 3 can move to a position relative to the detection component 4, so that the sensing component 3 is in a sensing position relative to the detection component 4. The sensing component 3 can also move to a position avoiding the detection component 4. The avoiding means that the position of the sensing component 3 is misaligned with the detection end 42 of the detection component 4, so that the detection component 4 cannot detect the sensing component 3. Then the sensing component 3 is in a non-sensing position relative to the detection component 4.

[0050] The detection component 4 has a sensing direction Y, which is the detection direction. When the detection component 4 adopts a ray-shaped sensor, the emission direction of the ray is the sensing direction Y. It can also be understood that the detection component 4 has a detection end 42, and the direction of the detection end 42 is the sensing direction Y. The movement direction of the sensing component 3 relative to the detection component 4 at the sensing position is the opening direction X, and the opening direction X is the lateral direction of the detection component 4.

[0051] In this example, we combine Figure 5-7As shown, by restricting the movement direction of the sensing component 3 relative to the detection component 4, the sensing component 3 moves in an active plane perpendicular to the sensing direction Y, and the active plane is the movement plane of the sensing component 3. It can be seen that the sensing component 3 moves from the lateral direction of the detection component 4 (i.e., the opening direction X of the sensing component 3) to the position relatively configured with the detection end 42 of the detection component 4, or the sensing component 3 moves laterally away from the end of the detection component 4 from the position relatively configured with the detection end 42 of the detection component 4. Then, the movement direction of the sensing component 3 relative to the detection component 4 can be defined as the opening direction X, that is, the sensing component 3 moves along the direction perpendicular to the sensing direction Y (i.e., the opening direction X) to the position relatively configured with the detection end 42 of the detection component 4. The sensing component 3 can only move in the active plane, and the sensing component 3 can only move relative to the detection component 4 along the opening direction X. The sensing component 3 cannot deviate from the active plane. It can be seen that the sensing component 3 cannot move toward or away from the detection component 4 along the sensing direction Y.

[0052] In the present embodiment, when the stamping equipment generates vibration during the stamping operation, the sensing component 3 is subjected to the vibration force, and the sensing component 3 can only move relative to the detection component 4 along the opening direction X, and the sensing component 3 will not move toward or away from the detection component 4 along the sensing direction Y. The vibration will not cause the sensing component 3 to flip over and avoid the detection end 42 of the detection component 4. The detection component 4 can always keep a fixed relative position or relative distance with the sensing component 3 in the sensing direction Y during the stamping vibration process, thereby ensuring that the storage limiter always maintains a stable signal, and the detection signal loss problem is not likely to occur, thereby ensuring the smooth progress of the stamping operation.

[0053] In one embodiment, referring to Figure 1 and Figure 5 As shown, the induction component 3 is rotatably connected to the second mold base 2 around a preset axis 7, and the preset axis 7 is perpendicular to the activity plane.

[0054] Specifically, the sensing component 3 rotates relative to the second mold base 2, and the sensing component 3 and the second mold base 2 can be rotatably connected via a hinge 5. The hinge 5 can adopt a hinge assembly. The hinge 5 includes a first hinge part 51, a second hinge part 52 and a hinge shaft 53. The first hinge part 51 and the second hinge part 52 are rotatably connected via the hinge shaft 53. The first hinge part 51 is connected to the sensing component 3, and the second hinge part 52 is connected to the second mold base 2, thereby realizing the rotation of the sensing component 3 relative to the second mold base 2.

[0055] The preset axis 7 is perpendicular to the active plane, that is, the preset axis 7 is parallel to the sensing direction Y. Therefore, it can be known that the sensing component 3 moves from the side of the detection end 42 to the position opposite to the detection end 42. Therefore, the sensing component 3 cannot approach or move away from the detection end 42 along the sensing direction Y at the front side of the detection end 42. In the sensing direction Y, the spacing distance between the sensing component 3 and the detection end 42 always remains stable. When stamping vibration occurs, in the sensing direction Y, the relative position of the sensing component 3 and the detection end 42 is fixed, and the problem of signal loss is not easy to occur, thereby reducing the probability of shutdown, which is conducive to ensuring the smooth progress of the stamping work.

[0056] For example, when the second mold base 2 is located below the first mold base 1, that is, the second mold base 2 is the lower mold base, the first mold base 1 is the upper mold base, and the vibration occurs in the vertical direction, the detection component 4 and the sensing component 3 are both connected to the second mold base 2, and the preset axis 7 is located above the detection component 4. The sensing component 3 rotates from the top to the bottom to be opposite to the detection component 4. Under the action of gravity, the sensing component 3 remains in the sensing position. During vibration, the sensing component 3 cannot move along the sensing direction Y, so the sensing component 3 cannot flip over. Along the sensing direction Y, the sensing component 3 always maintains a relatively stable state with the detection component 4.

[0057] Optionally, the sensing component 3 is slidably connected to the second mold base 2 along a first direction, and the first direction is parallel to the movable plane. The first direction can be understood as the opening direction Y mentioned above.

[0058] Specifically, the first direction may be any direction parallel to the active plane, wherein, for example, the first direction is a horizontal direction, the first direction may also be a vertical direction, or the first direction may also be a direction at any angle to the vertical direction or the horizontal direction.

[0059] The sensing component 3 is connected to the second mold base 2 by sliding along the first direction. A sliding groove can be provided on the second mold base 2 so that the sensing component 3 can be slidably configured in the sliding groove to slide along the first direction. Alternatively, the sensing component 3 and the second mold base 2 can be connected by a guide rail assembly to improve the sliding stability of the sensing component 3.

[0060] In this example, the sensing component 3 moves in a sliding manner relative to the second die base 2, so that the sensing component 3 can slide from the side to the detection end 42 of the detection component 4. Therefore, the sensing component 3 cannot approach or move away from the detection end 42 along the sensing direction Y at the front side of the detection end 42. In the sensing direction Y, the spacing distance between the sensing component 3 and the detection end 42 always remains stable. When stamping vibration occurs, in the sensing direction Y, the relative position of the sensing component 3 and the detection end 42 is fixed, and the problem of signal loss is not likely to occur, thereby reducing the probability of shutdown, which is conducive to ensuring the smooth progress of the stamping work.

[0061] In one embodiment, referring to Figure 1-5 As shown, when the sensing component 3 is connected to the second mold base 2 by rotation around the preset axis 7, the sensing component 3 includes a support member 31 and a sensing member 32 connected to the support member 31. The support member 31 is connected to the second mold base 2 by rotation around the preset axis 7. The support member 31 can rotate in the non-sensing position and be supported between the first mold base 1 and the second mold base 2. The sensing member 32 can be opposite to the detection component 4 in the sensing position.

[0062] Specifically, the support member 31 can be a rod-shaped or column-shaped support member 31, one end of the support member 31 can be rotatably connected to the second mold base 2 through a hinge 5, and the other end of the support member 31 can be connected to the sensing member 32. The support member 31 can be supported in the interval space between the second mold base 2 and the first mold base 1. In the sensing position, the sensing member 32 can be opposite to the detection end 42 of the detection component 4. Under the action of external force, the support member 31 is rotated around the preset axis 7, so that the sensing member 32 avoids the detection end 42 of the detection component 4. Then, the sensing member 32 is in a non-sensing position. The position where the sensing member 32 avoids the detection component 4 can be called a non-sensing position. Among the many non-sensing positions, one non-sensing position is the position where the support member 31 is supported between the first mold base 1 and the second mold base 2.

[0063] The support member 31 can play a supporting role between the first die base 1 and the second die base 2. Since, in the non-sensing position, the stamping equipment should be in a stopped and non-stamping state, therefore, in order to prevent abnormal stamping in the non-sensing position, the support member 31 can play a supporting role between the first die base 1 and the second die base 2 in the non-sensing position. During abnormal stamping, the support member 31 will prevent the relative movement of the first die base 1 and the second die base 2 on the one hand, and on the other hand, when the first die base 1 moves relative to the second die base 2, it will squeeze the support member 31 to emit a larger impact force, thereby generating an abnormal sound to remind the operator to discover abnormal dangers in time and play a warning role.

[0064] The sensing member 32 can be fixedly or detachably connected to the support member 31. The sensing member 32 has at least a sensing surface, and the sensing surface can be perpendicular to the sensing direction Y, wherein the verticality includes the sensing surface and the sensing direction Y being perpendicular at an angle of 90°, and can also include perpendicularity with a preset angle deviation, that is, the sensing surface and the sensing direction Y can have a deviation of less than 10°, so that the sensing surface can be blocked at the front end of the detection component 4.

[0065] In this embodiment, the support member 31 can play a supporting and protecting role between the first die base 1 and the second die base 2. The support member 31 is connected to the sensing member 32. The support member 31 rotates relative to the second die base 2, so that the sensing member 32 can switch between a sensing position opposite to the detection component 4 and a non-sensing position avoiding the detection component 4, ensuring that in the sensing direction Y, the relative position of the sensing component 3 and the detection end 42 is fixed, and the problem of signal loss is not likely to occur, thereby reducing the probability of shutdown, which is conducive to ensuring the smooth progress of the stamping work.

[0066] In one embodiment, referring to Figure 2-5 As shown, the support member 31 is a support member 31 extending in a linear shape, so that the support member 31 extends into a rod-shaped structure, a columnar structure or a cylindrical structure, and the cross-sectional outer contour of the support member 31 can be circular, elliptical or polygonal, see Figure 2 As shown, the cross section of the support member 31 is rectangular, and the support member 31 is a cylindrical structure.

[0067] The sensing member 32 can be plate-shaped, one surface of the sensing member 32 is the sensing surface, and the extension direction of the support member 31 is parallel to the sensing surface. The sensing member 32 can be fixedly or detachably connected to an extension end of the support member 31, and the other extension end of the support member 31 is connected to the second mold base 2 through a hinge 5.

[0068] In this embodiment, the support member 31 extends linearly to form a support structure that can support the first die base 1 and the second die base 2. The support member 31 can withstand the extrusion force to hinder the first die base 1 from moving toward the second die base 2, thereby playing a protective and warning role in the event of abnormal startup of the stamping equipment.

[0069] In one embodiment, referring to Figure 1-4 As shown, the second mold base 2 is located below the first mold base 1; the detection component 4 and the sensing component 3 are arranged in the vertical direction, and the detection component 4 is located below the preset axis 7; and the sensing direction Y is along the horizontal direction.

[0070] Specifically, the second mold base 2 is a lower mold base, the first mold base 1 is an upper mold base, the first mold base 1 is installed above the second mold base 2, and the first mold base 1 and the second mold base 2 are arranged opposite to each other.

[0071] The vertical direction is in the direction of stamping, so it can be known that the vibration direction is also along the vertical direction, and the first die base 1 and the second die base 2 both vibrate up and down in the vertical direction.

[0072] The detection component 4 is located below the preset axis 7. Therefore, it can be known that the sensing component 3 is rotated from the top and from the side (opening direction X) to the front end of the detection component 4, so that the sensing surface of the sensing element 32 is arranged opposite to the detection end 42 of the detection component 4. The sensing component 3 as a whole can rely on the action of gravity to remain in the vertical direction without deflection, so that the sensing element 32 is always in the sensing position.

[0073] Combination Figure 2-4 As shown, the rotation angle of the sensing component 3 can be 180°. In the non-sensing position, the support member 31 in the sensing component 3 can be supported between the first mold base 1 and the second mold base 2 along the vertical direction, and the extension direction of the support member 31 is along the vertical direction; when the support member 31 rotates 180°, the sensing component 3 is in the sensing position, and the support member 31 is still in the vertical direction after rotating 180°. Relying on the action of gravity, the support member 31 and the sensing member 32 can be maintained at the bottom of the rotation position, so that the sensing surface of the sensing member 32 is blocked at the detection end 42 of the detection component 4.

[0074] In this embodiment, the sensing component 3 can move from the non-sensing position between the first die base 1 and the second die base 2, rotate 180°, and then move from the side of the detection component 4 to the sensing position, and can rely on gravity to maintain the sensing position. When the stamping die assembly vibrates in the vertical direction, the vibration cannot cause the sensing component 3 to move away from or close to the detection component 4 along the sensing direction Y. In the sensing direction Y, the spacing distance between the sensing component 3 and the detection end 42 always remains stable, and the relative position of the sensing component 3 and the detection end 42 is fixed, which makes it less likely for signal loss to occur, thereby reducing the probability of shutdown, which is conducive to ensuring the smooth progress of the stamping work.

[0075] In one embodiment, referring to Figure 1-4 As shown, a receiving groove 21 is formed on the second mold base 2 , and the detection component 4 is installed in the receiving groove 21 .

[0076] Specifically, the accommodating groove 21 is opened on the side of the second mold base 2, and the detection component 4 can be installed in the accommodating groove 21 through the mounting bracket 41. The detection component 4 and the mounting bracket 41 can be detachably connected to facilitate the installation and removal of the detection component 4.

[0077] The sensing member 32 is connected to the extended end of the support member 31, and the sensing member 32 can protrude from the surface of the support member 31 in a direction deviating from the central axis of the support member 31, so that after the support member 31 is rotated to a vertical direction, in the sensing position, the sensing member 32 can penetrate into the accommodating groove 21 to block the front end of the detection end 42 of the detection component 4.

[0078] In this embodiment, the receiving groove 21 protects the detection component 4 , and the detection component 4 can be hidden in the receiving groove 21 to reduce the collision of external components with the detection component 4 .

[0079] In one embodiment, referring to Figure 1-3 As shown, a limiting structure 22 is formed on the second mold base 2, and the limiting structure 22 is used to limit the sensing component 3 to the sensing position.

[0080] Specifically, the limiting structure 22 can be an independent component, and the limiting structure 22 can be connected to the second mold base 2, so that when the sensing component 3 moves to the sensing position, the sensing component 3 is limited, so that the sensing component 3 cannot continue the previous movement and stays at a position relative to the detection component 4.

[0081] For example, at the sensing position, the support member 31 is extended in the vertical direction under the action of gravity, and the limiting structure 22 is located on the side of the support member 31 and connected to the second mold base 2. A limiting surface is formed on the limiting structure 22, so that the limiting surface abuts against the side of the support member 31, thereby limiting the continued rotation of the support member 31 to limit it at the sensing position.

[0082] The limiting structure 22 can also be integrally formed on the second mold base 2. For example, the limiting structure 22 is a limiting surface formed on the second mold base 2, and the limiting surface can be the side elevation of the second mold base 2. The side elevation of the second mold base 2 is parallel to the vertical direction. The support member 31 is rotated 180° from the position between the first mold base 1 and the second mold base 2 so that the outer surface of the support member 31 is in contact with the side elevation of the second mold base 2. Then, the side elevation of the second mold base 2 keeps the support member 31 and the sensing member 32 in the sensing position.

[0083] In this embodiment, a limiting structure 22 is provided at the sensing position so that the sensing component 3 can be automatically limited and maintained at the sensing position after rotation, thereby limiting the sensing component 3 and improving the stability of the sensing component 3 at the sensing position.

[0084] In one embodiment, referring to Figure 1 and Figure 2 and Figure 8 As shown, the storage limiter further includes a buffer component 6 , which is disposed between the sensing component 3 and the second mold base 2 to mitigate the impact of the second mold base 2 on the sensing component 3 .

[0085] Specifically, the buffer component 6 is made of elastic material, for example, the buffer component 6 can be made of rubber, silicone, sponge and other materials.

[0086] The buffer component 6 can be installed on the second mold base 2 or on the sensing component 3. The buffer component 6 is located at the position where the support member 31 of the sensing component 3 abuts against the second mold base 2. For example, in the sensing position, the side surface of the support member 31 abuts against the limiting surface of the second mold base 2. The buffer component 6 can be installed on the side surface of the support member 31 or on the limiting surface of the second mold base 2, so that the buffer component 6 is located between the side surface of the support member 31 and the limiting surface of the second mold base 2.

[0087] In this embodiment, a buffer component 6 is provided between the sensing component 3 and the second mold base 2, so that when the sensing component 3 rotates from the non-sensing position to the sensing position and abuts against the second mold base 2, the buffer component 6 can play a buffering role, thereby reducing the impact force of the second mold base 2 on the sensing component 3, reducing the generation of noise, and protecting both the sensing component 3 and the second mold base 2.

[0088] In one embodiment, a plurality of storage limiters are provided, and the plurality of storage limiters are arranged around the central axis of the first die base 1 or the second die base 2 and at intervals. For example, four storage limiters may be provided, and the four storage limiters may be respectively installed at the four diagonal positions of the second die base 2. When the sensing components 3 of the four storage limiters are all in the sensing position, the stamping equipment can perform the stamping operation only after receiving all the signals, so as to reduce the dangerous situation of starting the stamping due to missed operation and ensure the safety of stamping production.

[0089] In a specific embodiment, in combination Figure 1-8As shown, the stamping die assembly includes a first die base 1 and a second die base 2 which are arranged opposite to each other, and the stamping die assembly also includes a storage limiter, which includes a detection component 4 and a sensing component 3; the detection component 4 has a sensing direction Y, and the detection component 4 is installed on the second die base 2; the sensing component 3 is movably installed on the second die base 2, and the sensing component 3 can move in an active plane perpendicular to the sensing direction Y, so that the sensing component 3 can switch between a sensing position relative to the detection component 4 and a non-sensing position avoiding the detection component 4; the sensing component 3 is rotatably connected to the second die base 2 around a preset axis 7, the preset axis 7 is perpendicular to the active plane, and the preset axis 7 is located above the detection component 4, the sensing component 3 includes a support member 31 and a sensing member 32 connected to the support member 31, the support member 31 is rotatably connected to the second die base 2 around the preset axis 7, and the support member 31 can rotate in the non-sensing position and is supported on the first die base 1 and the second Between the mold base 2, the sensing member 32 can be opposite to the detection component 4 at the sensing position; the sensing member 32 has a sensing surface, which is perpendicular to the sensing direction Y; the support member 31 is a support member 31 extending linearly, and the extension direction of the support member 31 is parallel to the sensing surface; the support member 31 is rotatably connected to the second mold base 2 through a hinge 5; the second mold base 2 is located below the first mold base 1; the detection component 4 and the sensing component 3 are arranged in the vertical direction, and the detection component 4 is located below the preset axis 7; the sensing direction Y is along the horizontal direction; a receiving groove 21 is provided on the second mold base 2, and the detection component 4 is installed in the receiving groove 21; the detection component 4 includes a sensor; a limiting structure 22 is formed on the second mold base 2, and the limiting structure 22 is used to limit the sensing component 3 to the sensing position; the storage limiter also includes a buffer component 6, which is arranged between the sensing component 3 and the second mold base 2 to reduce the impact of the second mold base 2 on the sensing component 3.
