Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold strength testing technology, specifically to a testing device for mold strength testing. Background Technology
[0002] A mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being molded. It is often referred to as the "mother of industry." A mold is a tool that uses external force to shape a blank into a part with a specific shape and size. During the manufacturing process, the hardness of the mold needs to be tested.
[0003] Chinese Patent Publication No. CN213689208U discloses a strength testing device for precision product molds, including a pressure sensor, a mounting plate, an electric cylinder, and a top plate. The rotating end of a first motor drives a first threaded rod to rotate. Through the threaded engagement between the first threaded rod and a U-shaped plate, and the sliding of a first slider on a first slide rail, the U-shaped plate causes a first clamping plate to move closer to a second clamping plate, thereby clamping the mold. The rotating end of a second motor drives a first pulley to rotate, which in turn drives a second pulley via a belt to rotate a second threaded rod. Through the threaded engagement between the second threaded rod and a connecting groove, the connecting groove slides along a second slide rail, thereby driving the electric cylinder to move the pressure sensor along the axial direction of the second threaded rod. The rotating end of a third motor drives a third threaded rod to rotate, which in turn drives a second slider to move, thereby driving the electric cylinder to move the pressure sensor along the axial direction of the third threaded rod.
[0004] The above-mentioned device uses a first clamping plate and a second clamping plate to clamp the mold and then perform testing. However, the first clamping plate and the second clamping plate can only clamp molds with flat side walls. If it is necessary to clamp a round mold, the clamping force of the clamping plate is weak, which makes the mold easy to shake during testing. Utility Model Content
[0005] To address the aforementioned problems, a testing device for mold strength testing is provided. A drive motor rotates a bidirectional screw, which in turn moves the extrusion plates at both ends of the screw closer together. Simultaneously, it moves the contact blocks closer together until the contact blocks abut against the sidewall of the circular mold. At this point, rotating the adjusting screw further moves the U-shaped extrusion frame outside the adjusting screw, causing the guide block at one end of the U-shaped extrusion frame to move within the guide groove. This also causes a rotating block to rotate, allowing the rotating block to fit against the curved edge of the circular mold. Multiple rotatable blocks can stably clamp both the circular and flat molds.
[0006] To address the problems in the existing technology, this utility model provides a testing device for testing the strength of molds, including a testing base. The top of the testing base is provided with a testing component for pressure testing of the mold. An electric turntable is rotatably mounted on the top of the testing base. A placement plate for placing the mold is mounted on the top of the electric turntable. A clamping component for clamping molds of different shapes is movably mounted on the top of the electric turntable.
[0007] Preferably, the detection assembly includes a hydraulic rod movably disposed on the top of the detection seat, and a pressure sensor for detecting pressure is disposed at the movable end of the hydraulic rod.
[0008] Preferably, the clamping assembly includes a drive motor rotatably mounted on the top of an electric turntable. The output shaft of the drive motor is provided with a bidirectional screw via a coupling. Both ends of the bidirectional screw are threaded with extrusion plates for extruding the mold. Each of the two extrusion plates has an abutment block on its opposite side for clamping the flattening mold.
[0009] Preferably, both sides of the abutment block are rotatably provided with rotating blocks for clamping the circular mold, and the sidewalls of the rotating blocks are provided with anti-slip pads to prevent the circular mold from sliding.
[0010] Preferably, the extrusion plate is rotatably provided with an adjusting screw, one end of which is rotatably connected to the side wall of the contact block. The external thread of the adjusting screw is provided with a U-shaped extrusion frame, and both ends of the U-shaped extrusion frame are rotatably provided with guide blocks. The side wall of the rotating block is provided with a guide groove for the guide block to move.
[0011] Preferably, the bottom of the electric turntable is provided with multiple load-bearing rods, the bottom of the load-bearing rods is rotatably provided with ball bearings, and the top of the detection seat is provided with an annular groove for the ball bearings to move.
[0012] The advantages of this utility model compared to the prior art are:
[0013] 1. The drive motor drives the bidirectional screw to rotate, which in turn drives the extrusion plates at both ends of the bidirectional screw to move closer together. At the same time, it also drives the contact blocks to move closer together until the contact blocks abut against the side wall of the circular mold. At this time, rotating the adjusting screw further drives the U-shaped extrusion frame outside the adjusting screw to move, so that the guide block at one end of the U-shaped extrusion frame moves in the guide groove. At the same time, it also drives the rotating block to rotate, so that the rotating block can fit against the curved edge of the circular mold. The multiple rotating blocks can stably clamp the circular mold and the flat mold.
[0014] 2. By using an electric turntable, the mold can be rotated, which makes it convenient for the detection components to detect different positions of the mold and improves the accuracy of mold detection. When the electric turntable rotates, the load-bearing rod and ball bearings at the bottom will move along the annular groove. The load-bearing rod is used to prevent the detection components from being damaged by excessive pressure during detection. Attached Figure Description

Detailed Implementation
[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 6 As shown, this utility model provides:
[0024] A testing device for testing the strength of a mold includes a testing base 1, a testing component for pressure testing of the mold is provided on the top of the testing base 1, an electric turntable 2 is rotatably provided on the top of the testing base 1, a placement plate 9 for placing the mold is provided on the top of the electric turntable 2, and a clamping component for clamping molds of different shapes is movably provided on the top of the electric turntable 2.
[0025] The mold to be tested is placed on top of the placement plate 9, and then the clamping assembly is adjusted according to the shape of the mold so that the clamping assembly can fit the mold better. Finally, the strength of the mold is tested by the testing assembly.
[0026] like Figure 2 As shown, the detection assembly includes a hydraulic rod 3 movably mounted on the top of the detection seat 1, and a pressure sensor 4 for detecting pressure is provided at the movable end of the hydraulic rod 3.
[0027] The strength of the clamped mold can be tested by using the hydraulic rod 3 in conjunction with the pressure sensor 4. The hydraulic rod 3 applies a preset pressure load, while the pressure sensor 4 monitors and records the deformation of the mold under stress in real time.
[0028] like Figure 3 and Figure 4 As shown, the clamping assembly includes a drive motor 11 rotatably mounted on the top of the electric turntable 2. The output shaft of the drive motor 11 is provided with a bidirectional screw 6 via a coupling. Both ends of the bidirectional screw 6 are threaded with extrusion plates 5 for extruding molds. Each of the two extrusion plates 5 has a contact block 14 on its opposite side for clamping the flattening mold.
[0029] By starting the drive motor 11, the bidirectional screw 6 is rotated, which further drives the extrusion plates 5 at both ends of the bidirectional screw 6 to move closer to each other, and at the same time, it also drives the contact blocks 14 to move closer to each other, thereby clamping the flat mold.
[0030] like Figure 4 As shown, rotating blocks 7 for clamping the circular mold are rotatably provided on both sides of the contact block 14, and anti-slip pads 8 for preventing the circular mold from sliding are provided on the side walls of the rotating blocks 7.
[0031] Multiple rotatable blocks 7 can be used to stably clamp the circular mold, making it convenient for the detection component to clamp the circular mold. At the same time, the anti-slip pads 8 can increase the friction between the rotating blocks 7 and the mold, ensuring stability during detection.
[0032] like Figure 4 As shown, an adjusting screw 10 is rotatably installed inside the extrusion plate 5. One end of the adjusting screw 10 is rotatably connected to the side wall of the contact block 14. A U-shaped extrusion frame 12 is provided on the external thread of the adjusting screw 10. Guide blocks 13 are rotatably installed at both ends of the U-shaped extrusion frame 12. A guide groove is provided on the side wall of the rotating block 7 for the guide block 13 to move.
[0033] By rotating the adjusting screw 10, the U-shaped extrusion frame 12 outside the adjusting screw 10 is further moved, so that the guide block 13 at one end of the U-shaped extrusion frame 12 moves in the guide groove, and at the same time, the rotating block 7 is driven to rotate, so that the rotating block 7 can fit with the curved edge of the circular mold.
[0034] like Figure 5 As shown, the bottom of the electric turntable 2 is provided with multiple load-bearing rods 15, and the bottom of the load-bearing rods 15 is provided with rotatable balls 16. The top of the detection seat 1 is provided with an annular groove for the balls 16 to move.
[0035] The electric turntable 2 can drive the mold to rotate, which makes it convenient for the detection component to detect different positions of the mold and improves the accuracy of mold detection. When the electric turntable 2 rotates, the load-bearing rod 15 and the ball bearing 16 at the bottom will move along the annular groove. The load-bearing rod 15 is used to prevent the detection component from being damaged by excessive pressure during detection.
[0036] Working principle: When pressure testing is required on a flat mold, the flat mold is first placed on top of the placement plate 9. Then, the drive motor 11 is started to drive the bidirectional screw 6 to rotate, which in turn drives the extrusion plates 5 at both ends of the bidirectional screw 6 to move closer together. At the same time, the contact blocks 14 also move closer together, thereby clamping the flat mold. At this time, the strength of the clamped flat mold can be tested by using the hydraulic rod 3 in conjunction with the pressure sensor 4. When testing a circular mold, the above steps are repeated until the contact blocks 14 abut against the side wall of the circular mold. Then, the adjusting screw 10 is rotated, which in turn drives the U-shaped extrusion frame 12 outside the adjusting screw 10 to move. The guide block 13 at one end of the U-shaped extrusion frame 12 moves within the guide groove, simultaneously causing the rotating block 7 to rotate. This allows the rotating block 7 to fit against the curved edge of the circular mold. Multiple rotatable rotating blocks 7 can stably clamp both the circular and flat molds, facilitating the clamping of the circular mold by the detection component. At the same time, the electric turntable 2 can drive the mold to rotate, allowing the detection component to detect different positions of the mold and improving the accuracy of mold detection. When the electric turntable 2 rotates, the load-bearing rod 15 and ball bearings 16 at its bottom move along the annular groove. The load-bearing rod 15 prevents the detection component from applying excessive pressure during detection, which could damage the electric turntable 2.
