Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a clamp for mold processing. Background Art

[0002] Molds are essential tools in industrial production, used to transform raw materials into products of specific shapes and sizes through various processes, including injection molding, blow molding, extrusion, and die casting. These molds and tools transform raw materials into finished parts under the action of external forces. They are widely used in various manufacturing processes. During mold processing, a mold fixture is required to secure the mold and ensure stability during processing.

[0003] Chinese patent CN214135056U discloses a fixture for mold processing, including a base, with hydraulic push rods fixedly installed on the left and right sides of the top of the base, and vertical rods fixedly installed on the output ends of the hydraulic push rods, and the opposite sides of the two vertical rods are fixedly connected to the top plate. This fixture for mold processing drives the vertical rod and the first clamping plate to move up and down. Because a slide groove and a slider are provided, starting the first electric push rod can drive the first clamping plate to move left and right. By pulling the handle by hand, the second clamping plate is driven to move left and right under the elastic force of the spring. By providing a driving device, the second clamping plate can be driven up and down, thereby achieving the advantage of an adjustable clamp clamping position. After determining the clamping position, start the second electric push rod to drive the limit block to insert into the limit groove to fix the movable plate, thereby greatly improving the stability of the clamped mold. However, there are still defects that can be improved:

[0004] 1. In this utility model, a first electric push rod is provided to push the connecting rod to move, thereby allowing the first clamping plate to fix the mold. However, it should be noted that there is a certain height difference between the hydraulic push rod and the second electric push rod, which makes the first clamping plate and the second clamping plate unable to effectively limit the two sides of the object. At the same time, the electric push rod pushes the first clamping plate to move, and the presence of the spring in the second clamping plate causes the magnitude of the force on the two sides of the mold to be different. In summary, the mold cannot be effectively fixed, and the equipment is relatively complex.

[0005] 2. In this utility model, the operating table cannot be adjusted in height. At the same time, there is a certain error in the synchronization between the second electric push rod and the hydraulic push rod, which causes accuracy problems when clamping the mold later. At the same time, it should be noted that only the spring is used to connect the support rod and the second push rod. The spring is an elastic object, which will cause the second push rod to tilt, and eventually the first clamping plate and the second clamping plate will not be on the same horizontal plane.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0035] The present invention will be described in further detail below with reference to the accompanying drawings.

[0036] The working principle of this utility model is as follows Figure 1-Figure 2 As shown, a mold processing fixture includes: a base 1, a support platform 3 is provided above the base 1, and four support columns 2 are fixedly connected to the bottom end of the support platform 3. The four support columns 2 are diagonally arranged at the outer edge of the bottom end of the support platform 3, and the bottom ends of the four support columns 2 are fixedly connected to the top end of the base 1;

[0037] Then, a groove 5 is opened in the middle of the top of the support platform 3, and the front and rear parts on both sides above the groove 5 are fixedly connected to telescopic rods 6. The bottom ends of the telescopic rods 6 are fixedly connected to the top of the support platform 3. At the same time, the top ends of the four telescopic rods 6 are fixedly connected to the receiving seats 7.

[0038] In addition, a lifting device 8 is provided in the groove 5. The lifting device 8 cooperates with the receiving seat 7. When the lifting device 8 drives the receiving seat 7 to move up and down, the telescopic rod 6 is extended and retracted to ensure the stability of the displacement of the receiving seat 7.

[0039] Next, sliding holes 4 are opened in the middle of both sides of the top of the support platform 3, and clamping blocks 9 are set in the sliding holes 4 on both sides. The front and rear ends of the clamping blocks 9 are respectively slidably connected to the corresponding inner walls of the sliding holes 4. Then, the bottom ends of the clamping blocks 9 on both sides pass through the sliding holes 4 and are fixedly connected to the connecting blocks 10, and the top of the connecting block 10 is slidably connected to the bottom end of the support platform 3 by providing a slide rail. At this point, the clamping block 9 can be stably displaced in the sliding hole 4;

[0040] Finally, a transmission device 11 is provided in the middle of the bottom end of the support platform 3 , and the transmission device 11 can automatically drive the connecting blocks 10 on both sides to move toward the adjacent side or the separated side.

[0041] The above-mentioned structures together constitute the general appearance structure of the mold processing fixture of the present invention.

[0042] according to Figure 3 As shown, in order to further explain the specific working principle of the mold processing fixture of the present invention, the lifting device 8 includes a trapezoidal block 801 fixedly connected to the middle of the bottom end of the receiving seat 7;

[0043] Next, a bidirectional threaded rod 803 is provided in the groove 5. The two threaded portions of the bidirectional threaded rod 803 are threadedly connected to the trapezoidal block 2 802. It should be noted that the bottom ends of the two trapezoidal blocks 802 are slidably connected to the bottom wall of the groove 5 by providing a second slide rail, and the inclined surfaces of the two trapezoidal blocks 802 are arranged opposite to each other. The inclined surfaces of the two trapezoidal blocks 802 are in contact with the inclined surface of the trapezoidal block 1 801. When the trapezoidal blocks 802 on both sides are displaced toward the adjacent side, the trapezoidal block 1 801 can drive the receiving seat 7 to move upward.

[0044] Then, a servo motor 805 is fixedly connected to one end of the bidirectional threaded rod 803, and the other end of the bidirectional threaded rod 803 is rotatably connected to a rotating frame 804. Here, the bottom end of the rotating frame 804 is fixedly connected to the bottom wall of the groove 5. At the same time, the servo motor 805 is fixedly connected to the bottom wall of the groove 5 by providing a motor seat.

[0045] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: the servo motor 805 drives the bidirectional threaded rod 803 to rotate on the rotating frame 804, and the two trapezoidal blocks 802 threadedly connected to the bidirectional threaded rod 803 will be displaced toward the adjacent side. Since the inclined surfaces of the two trapezoidal blocks 802 are in contact with the inclined surfaces corresponding to the trapezoidal block 1 801, when the two trapezoidal blocks 802 are displaced toward the adjacent side, the two trapezoidal blocks 802 will push the trapezoidal block 1 801 to move upward, and the trapezoidal block 1 801 will drive the receiving seat 7 to move upward synchronously. During this process, the four telescopic rods 6 are extended.

[0046] according to Figures 4 to 5 As shown, in order to further explain the specific working principle of the mold processing fixture of the present invention, the above-mentioned transmission device 11 includes a rotating shaft 1101 rotatably connected to the middle part of the bottom end of the support platform 3;

[0047] Then, the lower part of the outer wall of the rotating shaft 1101 is fixedly connected to the driven gear 2 1103, and either side of the driven gear 2 1103 is meshed with a transmission gear 1105. The bottom end of the transmission gear 1105 is fixedly connected to the stepper motor 1106, and the stepper motor 1106 is fixedly connected to the base 1 through the motor base 2.

[0048] At this point, the stepper motor 1106 can indirectly drive the rotating shaft 1101 to rotate through the engagement of the transmission gear 1105 and the driven gear 2 1103;

[0049] At the same time, a driven gear 1102 is fixedly connected to the upper part of the outer wall of the rotating shaft 1101, and the front and rear ends of the driven gear 1102 are meshed with tooth plates 1104. The top of the tooth plate 1104 is slidably connected to the support platform 3 by a slide rail 3. Finally, the side of the tooth plate 1104 away from the driven gear 1102 is fixedly connected to the corresponding connecting block 10.

[0050] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: the stepper motor 1106 drives the transmission gear 1105 to rotate, and the driven gear 2 1103 engaged with the transmission gear 1105 drives the rotating shaft 1101 to rotate. During the rotation of the rotating shaft 1101, the driven gear 1 1102 fixedly connected to the rotating shaft 1101 will drive the two tooth plates 1104 to displace. When the tooth plates 1104 displace, the corresponding connecting blocks 10 will be driven to displace.

[0051] according to Figures 1 to 5 As shown, when in use, first use the servo motor 805 to drive the bidirectional threaded rod 803 to rotate according to the specific size of the mold, and then use the two trapezoidal blocks 802 and the trapezoidal block 1 801 to drive the receiving seat 7 to rise to a suitable height. Then, place the mold on the top of the receiving seat 7, and then start the stepper motor 1106, and indirectly drive the rotating shaft 1101 to rotate through the engagement of the transmission gear 1105 and the driven gear 2 1103. Then, the driven gear 1 1102 drives the two tooth plates 1104 to move toward the adjacent side. During this process, the tooth plate 1104 indirectly drives the clamping block 9 to move together through the connecting block 10. When the clamping blocks 9 on both sides fix the mold, the stepper motor 1106 stops running.

[0052] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.

[0053] In addition, the electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.
