Description

Technical Field

[0001] This utility model relates to the field of mold clamping technology, and in particular to a 90-degree swing clamp for mold clamping. Background Technology

[0002] A mold clamp is an industrial device used to fix, lock, and clamp molds during manufacturing and processing to ensure that the molds are stable and reliable during operation. The core function of a mold clamp is to apply sufficient force to the clamping device through certain mechanical or hydraulic means to keep the mold in a fixed state when subjected to working pressure or mechanical impact, so as to avoid affecting the operational accuracy or equipment safety due to loosening or displacement.

[0003] In existing technologies, clamping rods cannot swing at large angles. In non-working states, clamping rods still protrude partially or completely from the mounting plane or movement path of the mold. When changing molds or when the mold enters the equipment along a specific path, the protruding clamping rods will cause spatial interference and movement obstruction to the mold, making it impossible for the mold to move smoothly into or out of the predetermined workstation. This makes mold changing operations cumbersome and time-consuming, heavily reliant on manual intervention to avoid obstacles, and has become a major bottleneck in achieving fully automated, rapid mold changing production lines.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] This utility model provides a 90-degree swing clamp for mold clamping, which adopts a linkage mechanism that cooperates with piston drive and guide rotation assembly to realize the swing of clamping rod and reliable locking.

[0006] This utility model provides a 90-degree swing clamp for mold clamping, comprising: The base has an inwardly recessed side to form a receiving space, and one end of the base supports the mold. A clamping housing is disposed within the accommodating space and fixedly connected to the base. A movable cavity is formed in the center of the clamping housing, and a movable hole is formed at one end facing the base to communicate with the movable cavity. A first flow hole and a second flow hole are formed on the clamping housing, and both the first flow hole and the second flow hole communicate with the movable cavity. A piston is disposed in the movable cavity, and the piston performs reciprocating linear motion in the movable cavity. One end of the piston extends toward the base and passes through the movable hole, and a through hole is opened at the end of the piston near the movable hole. A clamping assembly is disposed at one end in the through hole. The clamping assembly rotates around the axis of the through hole to switch the working mode of the clamp. A guide rotation assembly, mounted on the clamping housing and located on one side of the piston, is used to control the rotation direction of the clamping assembly.

[0007] Furthermore, the clamping assembly includes: Clamp the rotating shaft and install it inside the through hole; A clamping rod is provided with a fixing hole, and the clamping rod is mounted on the clamping shaft through the fixing hole. The clamping assembly rotates around the axis of the through hole. A first guide plate is installed at one end of the clamping rod near the clamping shaft; The second guide plate is installed at one end of the clamping rod near the clamping shaft and is positioned opposite to the first guide plate.

[0008] Furthermore, both the first guide plate and the second guide plate have arc-shaped grooves, which face the guide rotation assembly.

[0009] Furthermore, the guide rotation assembly includes: Guide seat, mounted on the clamping housing; The first guide wheel is mounted on the guide seat and is close to the arc-shaped groove; The second guide wheel is mounted on the guide seat and is close to the arc-shaped groove; Wherein, the first guide wheel corresponds to the first guide plate, and the second guide wheel corresponds to the second guide plate.

[0010] Furthermore, the operating mode includes: In the release mode, the piston moves toward the clamping assembly, one end of the arc groove of the first guide plate abuts against the first guide wheel, one end of the arc groove of the second guide plate abuts against the second guide wheel, and the clamping rod rotates with the clamping shaft until the clamping rod is at 90° with the piston; In the clamping mode, the piston moves away from the clamping assembly, the other end of the arcuate groove of the first guide plate abuts against the first guide wheel, the other end of the arcuate groove of the second guide plate abuts against the second guide wheel, and the clamping rod rotates with the clamping shaft until the clamping rod is parallel to the piston.

[0011] Furthermore, the guide rotation assembly also includes a buffer block, which is mounted on the guide seat and is used to contact the clamping rod.

[0012] Furthermore, the guide rotation assembly also includes a detection switch disposed on the guide seat, used to detect whether the current operating mode of the clamp is the release mode or the clamping mode.

[0013] Furthermore, the clamping housing includes a clamping bottom cover and a clamping outer cover, the first flow hole is disposed on the clamping bottom cover, and the second flow hole is disposed on the clamping outer cover.

[0014] Furthermore, an expansion groove is provided on the clamping bottom cover, and the expansion groove connects the first flow hole and the movable cavity.

[0015] Furthermore, the clamping assembly is provided with an elastic component, which abuts against the piston.

[0016] The following technical effects can be achieved through the technical solution of this utility model: By placing the clamping housing within the base's receiving space and utilizing fluid-driven reciprocating piston motion, the clamping assembly is rotatably connected to the piston, with a guide rotation assembly controlling its swing trajectory. This allows the clamping rod to swing to a 90-degree angle with the piston under the guidance of the guide rotation assembly when the clamper switches to the release mode, eliminating spatial obstruction to the mold's entry and exit paths. In the clamping mode, the clamping rod can reliably swing to be parallel to the piston, thereby clamping the mold and achieving fast, unobstructed, automated mold changing.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This utility model provides a method such as Figures 1 to 9 The 90-degree swing clamp shown for mold clamping includes: The base 1 has an inward recess on one side to form a receiving space 11, and one end of the base 1 supports the mold. The clamping housing 2 is set in the receiving space 11 and fixedly connected to the base 1. The clamping housing 2 has a movable cavity 21 in the center and a movable hole 22 at one end facing the base 1 to connect to the movable cavity 21. The clamping housing 2 has a first flow hole 23 and a second flow hole 24, both of which are connected to the movable cavity 21. Piston 3 is set in movable cavity 21. Piston 3 reciprocates linearly in movable cavity 21. One end of piston 3 extends toward base 1 and passes through movable hole 22. A through hole 31 is opened at the end of piston 3 near movable hole 22. The clamping component 4 is set in the through hole 31 at one end. The clamping component 4 rotates around the axis of the through hole 31 to switch the working mode of the clamp. The guide rotation assembly 5 is mounted on the clamping housing 2 and located on one side of the piston 3. It is used to control the rotation direction of the clamping assembly 4.

[0023] The base 1 can be a structural component made of steel or cast iron with sufficient rigidity and strength, which can be flexibly installed in the place where it is needed, such as near the mold processing production line, or on the workbench for precision machining of parts. The base 1 can also be directly machined from a part of the machine tool, and the entire clamp can be installed on the machine tool as an auxiliary tool of the machine tool. The accommodating space 11 can be machined or directly cast. The upper end face of the base 1 is used to support the mold or mold base plate. Through holes are opened on the two end faces of the base 1 to connect the accommodating space 11. By setting the accommodating space 11, the clamping shell 2 can be embedded in the base 1, and a fastener can be set in the through hole to fix the clamping shell 2 and the base 1 together.

[0024] A movable hole 22 is provided on the end face of the clamping housing 2 facing the base 1 where the mold is placed. The movable hole 22 is connected to the internal movable cavity 21, providing a channel for the piston 3 to move up and down within the movable hole 22. Sealing rings can be added between the piston 3 and the movable cavity 21 and the movable hole 22 for sealing. Two independent fluid channels are provided on the clamping housing 2, namely the first flow hole 23 and the second flow hole 24. Both of these flow holes 31 are connected to the movable cavity 21. External fluid, such as hydraulic oil or compressed air, is alternately injected and discharged into different chambers within the movable cavity 21 through these two interfaces, such as a hydraulic station or a pneumatic valve, thereby driving the piston 3 to move.

[0025] One end of the clamping assembly 4 is disposed in the through hole 31 of the piston 3. A rotating shaft can pass through the through hole 31 to form a rotatable connection, so that the entire clamping assembly 4 can rotate around the axis of the through hole 31. When the piston 3 makes reciprocating linear motion, it will drive the clamping assembly 4 to move together.

[0026] Meanwhile, through the repeated contact between the guide rotation component 5 set on one side of the piston 3 and the clamping component 4, the clamping component 4 is constrained and guided, causing the clamping component 4 to swing around the axis of the through hole 31 under the external guidance, thereby realizing the switching of the clamping device's working mode, achieving the effect of avoiding the replacement of the mold, eliminating interference with the mold's movement path, making mold replacement more convenient, and quickly returning to the clamping state of the mold, providing reliable and stable clamping force.

[0027] In some embodiments of this utility model, such as Figures 5 to 7 As shown, the clamping assembly 4 includes: The clamping shaft 41, installed inside the through hole 31, is the swing center of the entire clamping assembly 4. The clamping shaft 41 passes through the through hole 31 of the piston 3 and is aligned with the axis of the through hole 31, thus defining the rotation center of the clamping assembly 4.

[0028] The clamping rod 42 has a fixing hole 421. The clamping rod 42 is installed on the clamping shaft 41 through the fixing hole 421. The clamping assembly 4 rotates around the axis of the through hole 31. The end of the clamping rod 42 that passes through the clamping shaft 41 is preferably set as two clamping plates. The fixing hole 421 is opened on the two clamping plates. The clamping shaft 41 is set in the fixing hole 421. The two clamping plates are respectively set on both sides of the piston 3. The clamping shaft 41 passes through the clamping plates at both ends. The two clamping plates can also suppress the clamping shaft 41 from shifting left and right in the fixing hole 421 of the clamping rod 42.

[0029] The first guide plate 43 is installed at one end of the clamping rod 42 near the clamping shaft 41; The second guide plate 44 is installed at one end of the clamping rod 42 near the clamping shaft 41 and is positioned opposite to the first guide plate 43.

[0030] The first guide plate 43 and the second guide plate 44 are arranged opposite each other on both sides of the clamping rod 42 with the axis of the clamping rod 42 as the plane of symmetry. They drive the entire clamping assembly 4 to rotate through contact and transmission with the guide rotation assembly 5, so that the clamping rod 42 is in different positions and the working mode is switched.

[0031] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, both the first guide plate 43 and the second guide plate 44 have arc-shaped grooves 45, which face the guide rotation assembly 5. The arc-shaped grooves 45 are set with a certain depth, so that the two sides of the arc-shaped grooves 45 facing the guide rotation assembly 5 have a large angle, which makes the angle limit obvious when contacting the guide rotation assembly 5. However, the piston 3 drives the clamping assembly 4 to make reciprocating linear motion. At this time, the curvature of the arc-shaped grooves 45 can be used in conjunction with the guide rotation assembly 5 to control the rotation of the clamping assembly 4, so that the piston 3 can move upward, but the clamping rod 42 does not move upward, but tilts until the clamping rod 42 is at 90° with the piston 3, achieving different working modes, that is, the release mode. Then the piston 3 moves in the opposite direction, so that the clamping rod 42 gradually returns to a state parallel to the piston 3 and in a line, that is, the clamping mode, thereby clamping the mold.

[0032] In some embodiments of this utility model, such as Figure 8 As shown, the guide rotation assembly 5 includes: The guide seat 51, mounted on the clamping housing 2, is a supporting and fixing component of the guide rotation assembly 5. It can be made of high-strength metal material to ensure that it can withstand the dynamic pressure of the first guide wheel 52 and the second guide wheel 53 and the load of long-term use. The first guide wheel 52 is mounted on the guide seat 51, near the arc groove 45; The second guide wheel 53 is mounted on the guide seat 51, near the arc groove 45; Among them, the first guide wheel 52 corresponds to the first guide plate 43, and the second guide wheel 53 corresponds to the second guide plate 44.

[0033] The guide seat 51 can be provided with extended guide strips on both sides of the piston 3, for mounting the first guide wheel 52 and the second guide wheel 53 on both sides of the piston 3 respectively. This makes the first guide wheel 52 correspond to the first guide plate 43 and the second guide wheel 53 correspond to the second guide plate 44. Thus, when the piston 3 drives the clamping rod 42, it further drives the arc grooves 45 on the first guide plate 43 and the second guide plate 44 to reciprocate from both ends to approach the first guide wheel 52 and the second guide wheel 53. This makes the first guide wheel 52 restrict the linear movement of the first guide plate 43 and convert the linear movement of the piston 3 along the arc of the arc groove 45 into the rotation of the clamping rod 42. The second guide wheel 53 does the same. This is done synchronously on both sides of the piston 3 to switch the working mode of the clamp.

[0034] Both the first guide wheel 52 and the second guide wheel 53 can adopt the structure of a cam roller follower, or the structure of a combination of wheel rim, rolling bearing and shaft.

[0035] In some embodiments of this utility model, the working modes include: Release mode, such as Figure 9 As shown, the piston 3 moves toward the clamping assembly 4. One end of the arc groove 45 of the first guide plate 43 abuts against the first guide wheel 52, and one end of the arc groove 45 of the second guide plate 44 abuts against the second guide wheel 53. The clamping rod 42 rotates with the clamping shaft 41 until the clamping rod 42 is at 90° with the piston 3. Clamping mode, such as Figure 1 As shown, the piston 3 moves away from the clamping assembly 4. The other end of the arc groove 45 of the first guide plate 43 abuts against the first guide wheel 52, and the other end of the arc groove 45 of the second guide plate 44 abuts against the second guide wheel 53. The clamping rod 42 rotates with the clamping shaft 41 until the clamping rod 42 is parallel to the piston 3.

[0036] Drive fluid, such as compressed air or low-pressure oil, is introduced into the first flow hole 23 of the clamping housing 2. The fluid pressure acts on the corresponding bearing surface of the piston 3, driving the piston 3 to move towards the clamping assembly 4. As the piston 3 moves upward, the entire clamping assembly 4 fixed on the piston 3 moves upward synchronously. During this process, the lower edge of the arc groove 45 of the first guide plate 43 abuts against and hooks the first guide wheel 52. At the same time, the lower edge of the arc groove 45 of the second guide plate 44 abuts against and hooks the second guide wheel 53. Since the positions of the first guide wheel 52 and the second guide wheel 53 are fixed by the first guide seat 51 and the second guide seat 51, the abutting and hooking of the two will generate a torque that forces the clamping assembly 4 to rotate when the piston 3 continues to move upward. Under the action of the torque, the clamping rod 42 rotates with the clamping shaft 41 until the angle between the central axis and the central axis of the piston 3 reaches 90°. At this time, the clamping rod 42 swings completely to one side of the receiving space 11 of the base 1, making room for the mold to move completely, and switching to the release mode.

[0037] Drive fluid, typically higher-pressure hydraulic oil, is introduced into the second flow hole 24 of the clamping housing 2. The fluid pressure drives the piston 3 to move away from the clamping assembly 4. The piston 3 drives the clamping assembly 4 to move downward. At this time, the other end of the arc groove 45 of the first guide plate 43, that is, the upper edge, moves in close contact with the cylindrical surface of the first guide wheel 52. At the same time, the upper edge of the arc groove 45 of the second guide plate 44 moves in close contact with the cylindrical surface of the second guide wheel 53. The curved contour of the arc groove 45 guides the clamping rod 42 to start rotating in the opposite direction from the 90° released state. Finally, under the constraint of the arc groove 45 and the guidance of the first guide wheel 52 and the second guide wheel 53, the clamping rod 42 rotates with the clamping shaft 41 until the central axis is parallel and coincident with the central axis of the piston 3, that is, in a vertical state on the same straight line. The end of the clamping rod 42 presses upward against the mold or mold base plate, thereby achieving stable locking of the mold.

[0038] In some embodiments of this utility model, such as Figure 8 As shown, the guide rotation assembly 5 also includes a buffer block 54, which is mounted on the guide seat 51 and located near the limit position of the clamping rod 42 during its swing stroke. This ensures that when the clamping rod 42 swings to the limit position of 90° with the piston 3, the clamping rod 42 or the parts connected to it can contact the buffer block 54, effectively absorbing and dissipating the remaining kinetic energy of the clamping rod 42 and its components. This avoids rigid impact between metal parts, significantly reduces impact stress, and prevents fatigue damage or deformation of structures such as the guide seat 51, clamping rod 42, and clamping shaft 41 due to long-term impact, greatly extending the service life of the clamp.

[0039] The buffer block 54 can be made of a non-metallic material with high elasticity, high damping coefficient and good energy absorption properties. As a preferred, non-limiting example, the buffer block 54205 can be made of materials such as polyurethane, rubber or engineering plastics.

[0040] In some embodiments of this utility model, such as Figure 8 As shown, the guide rotation assembly 5 also includes a detection switch 55, which is mounted on the guide seat 51. This switch detects whether the clamping device is in a loosening or clamping mode and converts the current mode into an electrical signal output to the outside to control the flow and stop of fluid. A dedicated loosening detection switch 55 and a clamping detection switch 55 can be used to form the entire detection switch 55, installed at different positions on the guide seat 51. When a component on the clamping assembly 4 enters the effective detection range of the corresponding detection switch 55, a signal is triggered. The detection switch 55 can be various types of non-contact or contact sensors, capable of instantly and accurately converting the physical position of the clamping rod 42 (loosening or clamping) into a clear electrical signal and transmitting it to the upper control system. This provides a basis for subsequent automated processes, such as allowing mold movement or stopping fluid delivery.

[0041] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the clamping housing 2 includes a clamping bottom cover 25 and a clamping outer shell 26. A first flow hole 23 is provided on the clamping bottom cover 25, and a second flow hole 24 is provided on the clamping outer shell 26. Dividing the clamping housing 2 into two parts simplifies the machining of the internal movable cavity 21 and the first and second flow holes 23 and 24, facilitating the assembly and maintenance of internal parts such as the piston 3. Furthermore, the first and second flow holes 23 and 24 are respectively provided on the clamping bottom cover 25 and the clamping outer shell 26, located on opposite sides of the linear motion direction of the piston 3 in cross-section. By supplying fluid to the first and second flow holes 23 and 24 respectively, the piston 3 is driven to perform linear motion in different directions, forming the reciprocating linear motion of the piston 3, thus providing the power basis for switching the working mode of the clamp.

[0042] In some embodiments of this utility model, such as Figure 4As shown, an expansion groove 251 is formed on the clamping bottom cover 25, which connects the first flow hole 23 and the movable cavity 21. The expansion groove 251 can be set as an annular groove surrounding the first flow hole 23, or as multiple radial flow channels radiating outward from the first flow hole 23, or as a circular cavity covering the projection area of ​​the lower end face of the piston 3. As long as the expansion groove 251 is machined in the area corresponding to the lower end face of the piston 3, it can avoid the lower end face of the piston 3 from generating a large static friction force with the inner end face of the clamping bottom cover 25 under the action of oil film surface tension and micro-unevenness. The expansion groove 251 allows the fluid to be instantly distributed to the entire working surface, applying an upward thrust from all directions at the same time, thereby easily and quickly overcoming the static friction force, effectively avoiding the starting delay or jamming of the piston 3, and ensuring the sensitivity and reliability of the clamping device response.

[0043] In some embodiments of this utility model, such as Figure 7 As shown, an elastic component 46 is provided on the clamping assembly 4. The elastic component 46 abuts against the piston 3. The elastic component 46 can be a combination of a spring and a steel ball. The steel ball is used to contact the piston 3. At the moment when the piston 3 drives the clamping assembly 4 to start swinging, the elastic component 46 absorbs and releases energy through its own flexible deformation, transforming the originally rigid and impactful starting process into a gentle and gradual acceleration process. This reduces the instantaneous impact load and stress peak generated at the clamping shaft 41, the contact point between the guide plate and the guide wheel, and other parts, effectively preventing microcracks or early fatigue damage caused by stress concentration. Furthermore, by buffering the impact and reducing friction, the elastic component 46 makes the clamping device's transition from clamping to releasing state more smooth and gentle, reducing the vibration and noise of the entire clamping device.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
