Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology for tooth holders, and specifically relates to a quick mold changing mechanism for die casting molds for tooth holders. Background Technology

[0002] Die-casting molds for gear seats are specialized tools used for die-casting gear seat parts. High pressure is provided by a die-casting machine to inject molten metal such as aluminum alloy or zinc alloy into the mold cavity. After cooling and solidification, a gear seat with a precise structure is formed. It is suitable for mechanical transmission systems such as automotive gearboxes and industrial gearboxes. The mold usually consists of a fixed mold, a moving mold, and a gating system. It is made of hot work die steel and must have good heat resistance and wear resistance. It can achieve efficient mass production of gear seats under high pressure.

[0003] However, in practical applications, die-casting molds for gear teeth mostly use multiple threaded pins as fixed connecting parts. Whenever the mold needs to be changed, operators have to use tools such as wrenches to disassemble the threaded pins one by one. After the old mold is removed, the new mold needs to be reinstalled and the threaded pins tightened for fixation. This traditional fixing method exposes significant drawbacks. The process of disassembling and installing the threaded pins is time-consuming and a single mold change often takes tens of minutes. The cumbersome operation process seriously hinders the realization of rapid mold change, frequently interrupts the production line, greatly restricts the improvement of production efficiency, and makes it difficult to meet the current demand for efficient and large-scale production.

[0004] To address the aforementioned issues, this application proposes a quick mold changing mechanism for die-casting molds with a tooth-shifting seat. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a quick mold changing mechanism for die-casting molds with a tooth-shifting seat, which enables rapid mold changing of the die-casting mold with a tooth-shifting seat.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick mold changing mechanism for a die-casting mold for a tooth-shifting seat, comprising a support plate, wherein a sliding groove frame and two sets of first electric push rods are fixedly connected to the upper surface of the support plate, a sliding connecting frame is slidably connected inside the sliding groove frame, a mold is arranged above the sliding connecting frame, a controller and two sets of second electric push rods are respectively arranged above the support plate, and a limit rod is fixedly connected to the telescopic end of each second electric push rod, wherein the ends of each set of limit rods that are close to each other pass through the sliding groove frame and extend into the interior of the sliding connecting frame.

[0007] As a preferred embodiment of this utility model, two sets of fixing pins are provided above the support plate, and the bottom end of each fixing pin passes through the support plate and extends to the bottom of the support plate.

[0010] As a preferred embodiment of this utility model, a reinforcing ring is fixedly connected to the outer surface of each of the first electric push rods, and the bottom surface of each reinforcing ring is fixedly connected to the upper surface of the support plate.

[0011] As a preferred embodiment of this utility model, each of the first electric push rods has a rubber pad fixedly connected to its telescopic end, and the upper surface of each rubber pad is in contact with the inner top wall of the sliding connecting frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a quick mold changing mechanism for a die-casting mold for a toothed seat, comprising a support plate 1, a sliding groove frame 2 and two sets of first electric push rods 10 fixedly connected to the upper surface of the support plate 1, a sliding connecting frame 3 slidably connected inside the sliding groove frame 2, a mold 15 arranged above the sliding connecting frame 3, a controller 8 and two sets of second electric push rods 6 arranged above the support plate 1, a limit rod 13 fixedly connected to the telescopic end of each second electric push rod 6, and the ends of each set of limit rods 13 that are close to each other passing through the sliding groove frame 2 and extending into the interior of the sliding connecting frame 3;

[0025] In this embodiment, the controller 8 adopts a PLC programmable logic controller, which has stable and reliable control performance and convenient programming interface. It can accurately control the extension and retraction stroke and speed of the first electric push rod 10 and the second electric push rod 6. At the same time, high-precision limiting holes are opened at corresponding positions of the sliding groove frame 2 and the sliding connecting frame 3. The hole size is precisely matched with the limiting rod 13, which can accurately extend and retract under the drive of the second electric push rod 6, realize precise limiting and quick unlocking of the sliding connecting frame 3, and ensure the positioning accuracy and stability of the mold 15 during installation and disassembly.

[0026] Specifically, two sets of fixing pins 5 are provided above the support plate 1. The bottom end of each fixing pin 5 passes through the support plate 1 and extends to the bottom of the support plate 1. In this embodiment, the support plate 1 is quickly positioned and fastened to the equipment reference surface by the precise cooperation between the fixing pins 5 and the preset holes of the die-casting machine worktable, forming a rigid connection between the mechanism and the host. This not only avoids displacement deviation caused by vibration during operation, but also provides a unified reference for the subsequent installation of the mold 15, ensuring the consistency of positioning when changing molds in different batches.

[0027] Specifically, a fixing plate 7 is fixedly connected to the bottom surface of the controller 8. The bottom surface of the fixing plate 7 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the fixing plate 7 is used to construct an independent installation platform for the controller 8, so that the controller 8 and the support plate 1 maintain a reasonable distance, which reduces the impact of equipment vibration on electronic components and provides operating space for circuit connection and maintenance.

[0028] Specifically, a reinforcing frame 4 is fixedly connected to the outer surface of the sliding groove frame 2. The bottom surface of the reinforcing frame 4 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the reinforcing frame 4 forms a support structure between the sliding groove frame 2 and the support plate 1, dispersing the lateral force transmitted by the mold 15 to the entire support plate 1, effectively enhancing the deformation resistance of the sliding groove frame 2, avoiding groove displacement after long-term use, and ensuring the smooth sliding and positioning accuracy of the sliding connecting frame 3.

[0029] Specifically, each first electric push rod 10 has a reinforcing ring 11 fixedly connected to its outer surface. The bottom surface of each reinforcing ring 11 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the reinforcing ring 11 forms a ring-shaped fixation for the first electric push rod 10, which enhances the connection rigidity between the push rod and the support plate 1. This can counteract the radial torque generated when the push rod extends or retracts, prevent the piston rod from bending or wearing unevenly due to uneven force, and extend the service life of the electric push rod.

[0030] Specifically, each first electric push rod 10 has a rubber pad 12 fixedly connected to its telescopic end. The upper surface of each rubber pad 12 is in contact with the inner top wall of the sliding connecting frame 3. In this embodiment, the rubber pad 12 achieves flexible contact between the electric push rod and the sliding connecting frame 3, which can buffer the impact force during the pushing process, reduce wear and noise caused by metal collision, and compensate for installation errors through the micro-deformation of the rubber, ensuring uniform transmission of the pushing force and improving the stability of the mold changing action.

[0031] Specifically, each second electric push rod 6 has a fixed bracket 9 fixedly connected to its outer surface, and the bottom surface of each fixed bracket 9 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the fixed bracket 9 is used to perform multi-directional positioning constraint on the second electric push rod 6 to ensure that the telescopic axis of the limit rod 13 is precisely aligned with the hole of the sliding groove frame 2, so as to avoid the limit rod 13 from getting stuck or deviating during the operation, and to ensure reliable locking and quick unlocking of the sliding connecting frame 3.

[0032] Specifically, a connecting plate 14 is fixedly connected to the upper surface of the sliding connecting frame 3. The upper surface of the connecting plate 14 is fixedly connected to the bottom surface of the mold 15. In this embodiment, the connecting plate 14 realizes the transition connection between the sliding connecting frame 3 and the mold 15, which not only ensures the rigidity transmission between the two, but also allows for the adaptation of various models of molds 15 by replacing the connecting plate 14 of different specifications, thereby improving the versatility of the mechanism and facilitating the individual maintenance and replacement of the mold 15.

[0033] The working principle and usage process of this utility model are as follows: First, the support plate 1 is precisely positioned and fixed at a preset position on the die-casting machine's worktable using the fixing pin 5, ensuring a stable and rigid connection between the entire mechanism and the die-casting machine host. Then, the mold 15 is assembled with the sliding connecting frame 3 via the connecting plate 14. The operator can push the sliding connecting frame 3 along the groove of the sliding slot frame 2, moving the mold 15 to the working position. At this time, the controller 8 activates the second electric push rod 6, driving the limit rod 13 to precisely extend and retract, allowing it to pass through the hole in the sliding slot frame 2 and insert into the limit hole of the sliding connecting frame 3. The automatic locking and fixing of mold 15 ensures positioning accuracy during the die-casting process. When mold 15 needs to be replaced, controller 8 controls the second electric push rod 6 to retract, driving the limit rod 13 to disengage from the sliding connecting frame 3 and releasing the locking state. At the same time, the first electric push rod 10 is activated, and its telescopic end pushes the sliding connecting frame 3 through the rubber pad 12, smoothly pushing the old mold 15 along with the sliding connecting frame 3 out of the sliding groove frame 2. After replacing the new mold 15, the above sliding positioning and locking steps are repeated to complete the entire mold replacement process. The entire process does not require disassembling the threaded pin, which greatly shortens the mold replacement time and improves production efficiency.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
