Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a quick mold blank changing mechanism and a die casting molding equipment. Background Technology

[0002] In the die-casting process, the efficiency of mold replacement significantly impacts production rhythm. Currently, mold replacement typically requires manual labor, involving steps such as adjusting the position of locating pins and tightening multiple sets of bolts one by one. This process is cumbersome and time-consuming. Furthermore, during mold hoisting, collisions between the mold and the die-casting machine's tie rods are prone to occur, potentially causing equipment damage. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome replacement and easy collision with tie rods, by proposing a quick mold blank replacement mechanism and die casting equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick mold base changing mechanism includes a mounting base, the surface of which is provided with an insert groove;

[0006] Three L-shaped limiting brackets are fixedly mounted on the surface of the mounting base and distributed around the side of the insert groove. Two of the L-shaped limiting brackets are located on the lateral sides of the mounting base surface, and the other L-shaped limiting bracket is located at the bottom of the mounting base surface. The three L-shaped limiting brackets together form a U-shaped positioning space for receiving the mold.

[0007] A limiting frame is fitted onto the outer wall of the mounting base;

[0008] Three L-shaped clamping brackets are provided. The mounting base is located on the side wall of each L-shaped limiting bracket and has a side hole that communicates with the embedding groove. A guide rod is fixedly provided between each side hole and the adjacent L-shaped limiting bracket. The three L-shaped clamping brackets are slidably sleeved on the outer wall of the three guide rods and housed inside the corresponding L-shaped limiting bracket. All three L-shaped clamping brackets are fixedly connected to the inner wall of the limiting frame.

[0009] In one possible design, both ends of the top of the limiting frame extend upward to form guide sections, and inclined grooves are provided on the opposite inner sidewalls of the two guide sections, with the distance between the two inclined grooves gradually narrowing from top to bottom.

[0010] In one possible design, the guide section extends upward above the die-casting machine's tie rod to guide and limit the mold during hoisting and lowering, preventing the mold from colliding with the tie rod.

[0011] In one possible design, mounting holes are provided at all four corners of the back of the mounting base.

[0012] A die-casting molding equipment, including the aforementioned quick mold changing mechanism, further includes:

[0013] body;

[0014] Two mold bases, one of which has a movable seat on its surface that can move along the Corinthian column, and the two mounting seats are respectively fixedly mounted on the surface of the movable seat and the surface of the other mold base;

[0015] A hydraulic cylinder is installed on the back of the mold base with the movable seat. The output shaft of the hydraulic cylinder passes through the mold base and is connected to the movable seat, and is used to drive the movable seat to open and close the mold on it.

[0016] In one possible design, the quick-change mold blank mechanism corresponding to the fixed mold has an injection port inside the mold, and the back of the corresponding mounting base has a clearance hole for clearance.

[0017] In one possible design, a driving component is fixedly installed on the machine body below the mold base. The output end of the driving component is connected to the corresponding limiting frame through a connecting bracket to drive the limiting frame to move.

[0018] The driving component is a hydraulic cylinder with a self-locking function.

[0019] In this application, during actual use, the mold is hoisted to the top of the machine body by a crane, and then the mold is controlled to fit with the corresponding guide section. Then, it is moved down along the guide section and inserted into the interior of the L-shaped limiting frame to avoid colliding with the tie rod. After completion, the connection with the crane is disconnected, and then the limiting frame is moved by the drive component. The limiting frame will drive the L-shaped clamping frame to move, thereby pushing the mold into and fixing it inside the insert slot. At this time, the surface of the mold is flush with or protrudes from the L-shaped limiting frame. At the same time, when the mold moves, it will drive the mold blank of the injection port to be inserted into the injection end of the machine body for connection.

[0020] Then, the hydraulic cylinder can be controlled to move the moving seat, thereby bringing the two molds together. Then, molten metal can be injected to perform the die casting process.

[0021] In this utility model, the quick mold blank changing mechanism and die casting equipment form a U-shaped positioning space through three L-shaped limiting frames. With the bidirectional clamping of the L-shaped clamping frame, the mold can be quickly inserted and fixedly installed, thereby improving its replacement efficiency.

[0022] In this utility model, the quick mold blank changing mechanism and die casting equipment are embedded and fixedly installed, and can be directly connected to the injection end of the original equipment during installation to realize the automatic docking of the molten metal injection channel.

[0023] In this invention, the clamping method replaces the original bolt installation during use, thereby improving efficiency. Furthermore, the clamping component can act as a guide during insertion and installation, thus guiding and limiting the hoisted mold and preventing it from colliding with the main body of the equipment and causing unnecessary damage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In one embodiment: Reference Figure 1-3A quick-change mold blank mechanism includes: a mounting base 1 with an insert groove 7 on its surface; three L-shaped limiting brackets 3 welded and fixed to the surface of the mounting base 1 and distributed around the side of the insert groove 7, wherein two L-shaped limiting brackets 3 are located on the lateral sides of the mounting base 1 and the third L-shaped limiting bracket 3 is located at the bottom. Side holes 5 are provided on the sidewalls of the mounting base 1 and the L-shaped limiting brackets 3 on the same side for communication with the insert groove 7; a guide rod 6 is fixedly provided between each L-shaped limiting bracket 3 and the adjacent side hole 5; and three L-shaped clamping brackets 8 are slidably sleeved on the outer wall of the guide rod 6 and located inside the corresponding L-shaped limiting bracket 3 for clamping and fixing the mold 4.

[0031] The limiting frame 2 is fitted onto the outer wall of the mounting base 1, and its inner wall is fixedly connected to three L-shaped clamping frames 8. The mold 4 is inserted from above into the U-shaped space formed by the three L-shaped limiting frames 3.

[0032] Guide sections 13 extend from both ends of the top of the limiting frame 2, and inclined grooves 12 are formed on the surface of the guide sections 13. The distance between the two inclined grooves 12 gradually narrows from top to bottom. Mounting holes 14 are provided at the four corners of the back of the mounting base 1, which are fixed to the die-casting machine mold base 17 by bolts. When the mold 4 is hoisted above the guide section 13 by the top lifting ring (not shown in the figure), it slides down along the inclined groove 12 on the inner side wall of the guide section 13, so as to be guided into the L-shaped limiting frame 3, thereby improving the stability during installation. Then, the limiting frame 2 is controlled to drive the L-shaped limiting frame 8 to move, thereby clamping and fixing the mold 4.

[0033] The die casting equipment includes the aforementioned quick mold blank changing mechanism, and also includes a machine body 15 and two mold bases 17. One mold base 17 has a movable seat on its surface that can move along the guide column. Two mounting seats 1 are respectively fixed to the movable seat and the surface of the other mold base 17. A hydraulic cylinder 16 is installed on the back of the mold base 17 with the movable seat, and its output shaft passes through the mold base 17 and is connected to the movable seat. The closure of the two molds is achieved by controlling the hydraulic cylinder 16.

[0034] Guide section 13 extends above the die-casting machine gatepost to prevent collision with the gatepost during installation.

[0035] This application can be used in the field of mechanical manufacturing, or in other fields applicable to this application.

[0036] In another embodiment: Reference Figure 4 A die-casting molding equipment is applied in the field of mechanical manufacturing. In one of the quick-change mold blank mechanisms, the mold 4 is provided with an injection port 10 and a clearance hole 9 is opened on the back of the mounting seat 1. When the mold 4 is installed, its injection port 10 extends to the clearance hole 9 and moves downward. Then, when the mold 4 is fixed in the insert groove 7, its injection port is connected to the molten metal injection end of the machine body 15.

[0037] The machine body 15 is fixedly installed below the mold base 17 with a drive component 18, which is preferably a self-locking hydraulic cylinder. The output end of the drive component is connected to the corresponding limit frame 2 through a connecting frame.

[0038] The side walls of the limiting frame 2 and the L-shaped limiting bracket 3 are provided with matching connecting holes 11, which can be used to connect them with bolts as needed to achieve further fixation.

[0039] However, as is well known to those skilled in the art, the working principle and wiring method of hydraulic cylinders are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
