Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, specifically a precision mold frame with rapid positioning function. Background Technology

[0002] A mold frame is the support for a mold. For example, on a die-casting machine, the part that combines and fixes the various parts of the mold according to certain rules and positions, and enables the mold to be installed on the die-casting machine for operation, is called the mold frame. When processing parts of various shapes, multiple shapes of molds are often required, which necessitates frequent mold changes. The mold core needs to be positioned during installation.

[0003] The existing technology has the following shortcomings: Application number 202211576144.2 proposes a precision mold frame with rapid positioning function, relating to the field of mold frame technology. It includes a support assembly, which includes a mounting top plate. Four guide slide rods are fixedly mounted on the mounting top plate, and a mounting base is fixedly mounted on the guide slide rods. A bottom mold fixing module is fixedly mounted on the mounting base, and the bottom mold fixing module includes a cavity mold fixing seat. The separation protrusion of this invention allows gas to be ejected upwards when the top of the separation protrusion separates from the through hole in the auxiliary vent, thereby detaching the formed part attached to the cavity mold. Since the separation protrusion is flush with the inner wall of the cavity mold, it reduces burr defects on the surface of the formed part. By setting the bottom mold fixing module and the top mold fixing module, the mold core does not need to be deliberately positioned during installation; it only needs to be placed in an approximate position to complete the positioning and installation, reducing the time required for mold core replacement.

[0004] In the aforementioned equipment, although the structure for mold replacement, positioning, and installation does not require deliberate positioning, in practice, the punch limit frame and die limit frame can only restrict the front and rear positions of the mold. They cannot restrict or position the installation positions on both sides of the mold, resulting in insufficient precision in mold installation and positioning. Furthermore, the punch limit frame and die limit frame are not convenient enough for fixing the mold during installation. When it is necessary to fix the mold, the ease of operation can be further improved. Utility Model Content

The limiting member is T-shaped and inserted into the horizontal sliding opening and the vertical sliding opening. The width of the limiting member is adapted to the horizontal sliding opening and the vertical sliding opening.

[0011] As a preferred technical solution of this utility model: the insertion rod is fixedly installed on one side of the upper part of the limiting member, the insertion rod is located in the mounting groove, and the insertion rod is adapted to the fixing hole.

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.

[0024] In this embodiment, four sets of fixing rods 2 are fixedly installed on the base 1. The fixing rods 2 pass through the die mounting plate 3 and are fixedly connected to the die mounting plate 3. A spring assembly is provided inside the fixing rods 2. The guide rods 4 are inserted into the fixing rods 2 and are fixedly connected to the spring assembly inside the fixing rods 2. The top plate 5 is fixedly installed on the top of the guide rods 4. The guide rods 4 pass through the punch mounting plate 6 and are fixedly connected to the punch mounting plate 6. The top plate 5 is connected to the output end of the external drive device. Then, the required die 7 and punch 8 are installed on the mold frame. During the process, the top plate 5 and punch mounting plate 6 are lifted by the external drive device, and the punch 8 and die 7 are combined and placed together in the mounting groove 301.

[0025] Specifically, the fixing rod 2 and the guide rod 4 can ensure that the base 1, the die mounting plate 3, the punch mounting plate 6 and the top plate 5 correspond to each other and avoid deviation. The punch mounting plate 6 facilitates the installation of the punch 8 and the die mounting plate 3 facilitates the installation of the die 7.

[0026] Please see Figure 2 , Figure 3 The die mounting plate 3 includes a mounting groove 301, a transverse slide 302, a limiting member 303, a plug rod 304, a longitudinal slide 305, a motor 306, a mounting plate 307, and a threaded rod 308. The mounting groove 301 has a transverse slide 302 and a longitudinal slide 305. The transverse slide 302 has a limiting member 303. The bottom of the die mounting plate 3 is provided with a motor 306 and a mounting plate 307. The output end of the motor 306 is provided with a threaded rod 308.

[0027] In this embodiment, there are two sets of transverse sliding openings 302 and two sets of longitudinal sliding openings 305, which are symmetrically arranged. The limiting member 303 is T-shaped and is inserted into the transverse sliding opening 302 and the longitudinal sliding opening 305. The width of the limiting member 303 is adapted to the transverse sliding opening 302 and the longitudinal sliding opening 305. The length of the limiting member 303 in the transverse sliding opening 302 is greater than that in the corresponding longitudinal sliding opening 305. The mounting plate 307 is fixedly installed at the bottom of the die mounting plate 3, and the motor 306 is fixedly installed on the die mounting plate. 3. The bottom is symmetrical to the mounting plate 307. One end of the threaded rod 308 is fixedly connected to the output end of the motor 306. The other end of the threaded rod 308 passes through the limiting members 303 in the two sets of transverse sliding ports 302 and is rotatably connected to the mounting plate 307. The threads at both ends of the threaded rod 308 are set in opposite directions. There is a threaded connection between the threaded rod 308 and the limiting members 303. The installation structure of the limiting members 303 inside the longitudinal sliding port 305 is the same as the installation structure of the limiting members 303 inside the transverse sliding port 302. The punch is installed... The structure of mounting plate 6 is consistent with and symmetrical to the structure of die mounting plate 3. The starting motor 306 drives the threaded rod 308 to rotate. Due to the bidirectional thread structure of the threaded rod 308, it can simultaneously drive the limiting members 303 in the two sets of transverse slides 302 to move closer to the center. The limiting members 303 in the longitudinal slide 305 are driven by their corresponding motors 306 and threaded rods 308. The principle is the same. Since the longitudinal and transverse limiting members 303 move closer to the center synchronously, the space between the two sets of transverse limiting members 303 and the space between the two sets of longitudinal limiting members 303 are both in the middle of the mounting groove 301, ensuring that the die 7 is in the center position of the mounting groove 301. The external drive device is controlled to drive the top plate 5 and the punch mounting plate 6 to descend. The mounting groove 301 at the bottom of the punch mounting plate 6 covers the top of the punch 8. The mounting structure of the punch 8 on the punch mounting plate 6 is consistent with the mounting structure of the die 7 on the die mounting plate 3. It can simultaneously limit and position the four sides of the installed mold, improving the accuracy of mold installation.

[0028] Specifically, the position of the die 7 can be restricted by the limiting member 303, the longitudinal slide 305 and the transverse slide 302 facilitate the movement of the limiting member 303, the motor 306 provides sufficient power for the rotation of the threaded rod 308, the threaded rod 308 facilitates the synchronous movement of the limiting member 303, the motor 306 is specifically a brake motor and is connected to an external reversing switch to facilitate the control of the forward and reverse rotation of the motor 306, and the mounting plate 307 facilitates the installation of the threaded rod 308.

[0029] Please see Figure 4 A fixing hole 9 is provided on the outer side of the die 7, and a rod 304 is provided on one side of the limiting member 303;

[0030] In this embodiment, the insertion rod 304 is adapted to the fixing hole 9, and the insertion rod 304 is fixedly installed on one side of the upper part of the limiting member 303. The insertion rod 304 is located in the mounting groove 301. During the installation of the punch 8 and the die 7, the insertion rod 304 will be inserted into the corresponding fixing hole 9, which can ensure the stability of the punch 8 and the die 7. The fixing of the punch 8 and the die 7 can be completed during the positioning process, which improves the speed of mold installation.

[0031] Specifically, the insertion rod 304 and the fixing hole 9 facilitate the stability of the die 7 within the mounting groove 301.

[0032] 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.
