The pushing electric cylinder 322 pushes the sliding block 323 to move left and right on the sliding frame body 321. While realizing the movement of the movable insert 345, the side-mounted limiting rod 37 supports the starting die holder 1 and the moving die core 2 to move upward, realizing the mold opening control of the mold casting device. The connection between the die-cast product 346 and the mold frame 342 has become loose, facilitating the ejection of the die-cast product 346.

[0031] Refer to Figure 6 , a set of mold frames 342 are respectively provided at the left and right ends of the fixed die core 34. Multiple sets of overflow channels 341 are respectively provided at the bottoms of the mold frames 342. An inlet channel 343 is provided at the input ends of the two sets of mold frames 342. The input end of the inlet channel 343 is connected to the inside of the feeding fixed seat 305. A feeding port 344 is provided at the top of the feeding fixed seat 305. A die-cast product 346 is provided on the mold frame 342. A movable insert 345 is provided inside the die-cast product 346.

The mold casting raw material enters the inlet channel 343 from the feeding port 344, and the inlet channel 343 provides die-casting raw materials to the two sets of mold casting devices. To ensure the structural integrity of the die-cast product 346, the raw materials flowing into the mold casting device will be slightly more than the amount of raw materials required for the die-cast product 346. The excess raw materials will flow out from the overflow channels 341, facilitating collection and reuse, and avoiding the influence of the raw material amount on the structural performance of the die-cast product 346; before die-casting, the movable insert 345 is placed at the designated position on the mold frame 342. When the die-cast product 346 is cooled and formed, the movable insert 345 is embedded in the die-cast product 346, facilitating the side-mounted sliding frame 32 and its components to cooperate with the moving die ejector rod 310 to eject the die-cast product 346, realizing the demolding process of the die-cast product 346.

[0032] Refer to Figure 7 , the die-cast product 346 that has completed demolding is in a connected state with the movable insert 345. This mold casting process is also equipped with a fixed tooling 348 for separating the die-cast product 346 from the movable insert 345. The die-cast product 346 is placed on the fixed tooling 348, and the extrusion rod 347 is nailed into the die-cast product from the side circular hole, and the movable insert 345 can be extruded from the die-cast product 346.

[0033] Participate in Figure 2 and Figure 3, the setting components of the main sliding frame 33 and the side sliding frame 32 are the same. The main sliding frame 33 is respectively provided with main limit rods 38. The main sliding frame 33 is used to limit the opening and closing mold control of the moving mold core 2 and the fixed mold core 34, ensuring the smooth progress of mold opening and closing. During mold closing, the main sliding frame 33 is provided with a pushing electric cylinder to act on its sliding block to move inward, limiting the installation of the moving mold core 2. At this time, the main limit rod 38 contacts the edge of the moving mold core 2 to prevent the moving mold core 2 from generating displacement. During mold opening, the main sliding frame 33 is provided with a pushing electric cylinder to act on its sliding block to move outward, and the limiting effect of the main limit rod 38 on the moving mold core 2 disappears, facilitating the sliding component of the side sliding frame 32 to jack up the moving mold core 2 to complete the mold opening control.

[0034] Refer to Figure 2 and Figure 3 , four groups of mold connecting frames 36 are provided at the bottom of the fixed mold base 3. The mold connecting frames 36 are embedded in the face pin plate 4. The bottom of the fixed mold base 3 realizes the first-stage limit setting for the face pin plate 4 by setting the mold connecting frames 36, enhancing the supporting effect of the face pin plate 4 on the fixed mold base 3.

[0035] A set of fixing columns 39 are respectively provided on the outer sides of the mold connecting frames 36. Anti-disengagement parts are provided on the fixing columns 39 and are arranged in the face pin plate 4. The bottoms of the fixing columns 39 are embedded in the bottom pin plate 5. The bottom of the fixed mold base 3 establishes the connection to the face pin plate 4 and the bottom pin plate 5 by setting the fixing columns 39, and enhances the connection firmness to the face pin plate 4 through the anti-disengagement parts, realizing the second-stage limit setting for the face pin plate 4, and avoiding the negative impact of the working vibration during mold opening and closing on the installation of the face pin plate 4 and the bottom pin plate 5.

[0036] A number of moving mold ejector rods 310 are provided on the casting mold setting frame 306. The moving mold ejector rods 310 are used to eject the die-casting product 346 from the casting mold frame 342 to realize the demolding treatment of the die-casting product 346.

[0037] The feeding port 344 extends into the panel of the moving mold base 1. The front end of the moving mold base 1 fills the die-casting raw material from the feeding port 344 to realize the raw material supply to the casting mold device.

[0038] Embedded columns are respectively provided at the top of the fixed vertical frame 31. The embedded columns respectively extend into the four corners of the moving mold base 1. The top of the fixed vertical frame 31 limits the connection to the moving mold base 1 through the embedded columns, that is, the moving mold base 1 can only move vertically up and down during the opening and closing of the mold, ensuring the accurate control of mold opening and closing for the casting mold assembly.

[0039] A rapid die-casting mold using reverse draw for demolding provided by an embodiment of the present utility model. The die-casting product of this device is designed with a reverse draw round hole, and it is difficult to achieve its demolding control with the conventional mold design. Before die-casting, the movable insert 345 is placed on the die-casting frame 342. During the condensation and molding after the die-casting raw material is poured in, the movable insert 345 and the die-casting product 346 are an integral structure. When the two sets of side sliding frames 32 cooperate with the side limit rods 37 to move inward to control the opening of the mold, the movable insert 345 is extruded, causing the connection between the die-casting product 346 and the mold frame 342 to become loose, facilitating the ejector rod 310 of the moving mold to eject the die-casting product 346 to achieve demolding control.

[0040] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
