Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and in particular to a die casting mold frame that facilitates the replacement of local parts of the mold core. Background Technology

[0002] The die-casting mold base is an indispensable core component in the die-casting process. It mainly consists of the mold structure frame, guiding system, support components, and auxiliary devices. Its quality directly affects the precision of the die-cast parts, production efficiency, and mold life. As the "skeleton" of the die-casting mold, it not only provides stable support for the mold cavity but also ensures the accuracy of mold opening and closing actions through the guiding mechanism. At the same time, it assists in key processes such as filling and cooling of molten metal and demolding of castings.

[0003] However, when replacing the inner mold core of some existing large molds, it is often necessary to disassemble the entire mold plate, resulting in long downtime and low maintenance efficiency; moreover, the original waist-shaped groove is difficult to process and has limited positioning accuracy; in addition, the sprue bushing is integrally formed with the fixed mold, which means that the entire fixed mold must be replaced when changing the sprue type, increasing costs and time.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a die-casting mold frame that facilitates the replacement of local parts of the mold core, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A die-casting mold frame for easy replacement of mold core parts includes a moving mold and a fixed mold. A limit device is fixedly installed in the middle of the upper end of the moving mold, and a hydraulic cylinder bracket is fixedly installed at the left end and the front end of the moving mold. Four No. 1 screw holes are opened at the upper end of the moving mold, and a slot is opened in the middle of the upper end of the moving mold, in which the mold core is engaged.

[0008] Preferably, a positioning groove is formed on the inner wall of the fixed mold. The positioning groove on the inner wall of the fixed mold is a waist-shaped groove, which replaces the previous T-shaped groove design. The waist-shaped groove is easier to process and open than the T-shaped groove, thus improving processing efficiency.

[0009] Preferably, the fixed mold has an injection port at its lower end, and a sprue sleeve is installed inside the injection port. The sprue sleeve is snapped into the injection port on the fixed mold, and the sprue sleeve is installed inside the injection port by screws. By loosening the screws, the sprue sleeve can be replaced, supporting quick switching between different sprue specifications without disassembling the entire fixed mold.

[0010] Preferably, the limiting device includes a limiting plate with four No. 2 screw holes at its upper end. Each of the four No. 2 screw holes is fitted with a mounting screw, and the limiting plate is fixed to the upper center of the moving mold by the mounting screws. By unscrewing the mounting screws out of the corresponding No. 1 and No. 2 screw holes, the limiting plate can be lifted, thereby releasing the limiting effect on the mold core. This allows the mold core to be quickly removed and replaced without disassembling the entire moving mold.

[0011] Preferably, the positioning groove is a waist-shaped groove.

[0012] Preferably, the mounting screws are of the same specifications as screw holes No. 1 and No. 2 and are positioned vertically correspondingly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The mold core is inserted into the moving mold through the slot. When the mold core needs to be replaced, the mounting screws are unscrewed out of the corresponding screw holes No. 1 and No. 2. At this time, the limiting plate can be lifted to release the limiting of the mold core, so that the mold core can be quickly taken out for replacement without disassembling the entire moving mold.

[0015] 2. A sprue sleeve is snapped into the injection port on the fixed mold, and the sprue sleeve is installed in the injection port by screws. The sprue sleeve can be replaced by loosening the screws, which supports quick switching between different sprue specifications without disassembling the entire fixed mold.

[0016] 3. The positioning groove on the inner wall of the fixed mold is a waist-shaped groove, replacing the previous T-shaped groove design. The waist-shaped groove is easier to process and open than the T-shaped groove, thus improving processing efficiency. Attached Figure Description

[0026] like Figures 1-5 As shown, a die-casting mold frame that facilitates the replacement of local parts of the mold core includes a moving mold 1 and a fixed mold 2. A limiting device 3 is fixedly installed in the middle of the upper end of the moving mold 1, and a hydraulic cylinder bracket 4 is fixedly installed in the left end and the front end of the moving mold 1. Four No. 1 screw holes 10 are opened in the upper end of the moving mold 1, and a slot 11 is opened in the middle of the upper end of the moving mold 1, in which the mold core 12 is engaged.

[0027] A positioning groove 22 is provided on the inner wall of the fixed mold 2; the positioning groove 22 is a waist-shaped groove. By using a waist-shaped groove on the inner wall of the fixed mold 2 to replace the previous T-shaped groove design, the waist-shaped groove is easier to process and open than the T-shaped groove, thus improving processing efficiency.

[0028] The fixed mold 2 has an injection port 20 at its lower end, and a sprue sleeve 21 is installed inside the injection port 20. The sprue sleeve 21 is snapped into the injection port 20 on the fixed mold 2, and the sprue sleeve 21 is installed inside the injection port 20 by screws. The sprue sleeve 21 can be replaced by loosening the screws, which supports quick switching between different sprue specifications without disassembling the entire fixed mold 2.

[0029] The limiting device 3 includes a limiting plate 30, with four No. 2 screw holes 31 on its upper end. Each of the four No. 2 screw holes 31 is fitted with a mounting screw 32.

The mounting screws 32 are of the same specifications as the No. 1 screw hole 10 and the No. 2 screw hole 31, and their positions correspond vertically. By unscrewing the mounting screws 32 out of the corresponding No. 1 screw hole 10 and No. 2 screw hole 31, the limiting plate 30 can be lifted, thereby releasing the limiting effect on the mold core 12. This allows the mold core 12 to be quickly removed and replaced without disassembling the entire moving mold 1.

[0030] It should be noted that this utility model is a die-casting mold frame that facilitates the replacement of parts of the mold core. The mold core 12 is inserted into the moving mold 1 through the slot 11. When the mold core 12 needs to be replaced, the mounting screw 32 is unscrewed out of the corresponding screw hole 10 and screw hole 31. At this time, the limiting plate 30 can be lifted to loosen the limiting of the mold core 12, so that the mold core 12 can be quickly removed and replaced without disassembling the entire moving mold 1. In addition, the injection port 20 on the fixed mold 2 is fitted with a sprue sleeve 21, and the sprue sleeve 21 is installed in the injection port 20 by screws. By loosening the screws, the sprue sleeve 21 can be replaced, supporting quick switching of different sprue specifications without disassembling the entire fixed mold 2. In addition, the positioning groove 22 on the inner wall of the fixed mold 2 is a waist-shaped groove, replacing the previous T-shaped groove design. The waist-shaped groove is easier to process and open than the T-shaped groove, improving processing efficiency.
