Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically to an integral ejection die casting mold with an insert. Background Technology

[0002] Die casting molds are molds used to rapidly fill liquid or semi-liquid metal into a mold cavity under high pressure, and then solidify it under pressure to obtain metal parts of the required shape and size. Liquid metal (such as aluminum alloy, zinc alloy, magnesium alloy, etc.) is injected into the mold cavity at high speed and high pressure through a die casting machine. However, in the existing molds, inserts may shift due to uneven force during the ejection process, leading to an increased product defect rate. Multiple operations are required to completely remove the inserts and the formed metal body, reducing the efficiency of the removal process. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: an integral die-casting mold for inserts, comprising: a first mold 1; a second mold 2 placed above the first mold 1, which cooperates with the first mold 1; slots 7 symmetrically formed inside the first mold 1; an insert fixing mold 8 slidably disposed inside the slots 7; an inner sliding top plate 11 slidably disposed inside the first mold 1, with a plurality of first ejector pins 9 symmetrically fixed to one side of the inner sliding top plate 11, which are slidably connected to the first mold 1; a limiting module 6 symmetrically fixed to the bottom of the second mold 2, which cooperates with the slots 7 and the insert fixing mold 8; a buffer assembly placed inside the inner sliding top plate 11, which is connected to the first mold 1; and second ejector pins 10 symmetrically fixed to the bottom of the insert fixing mold 8, which are slidably connected to the first mold 1 and fixed to the inner sliding top plate 11.

[0028] It should be noted that in this embodiment, before die casting, the insert is placed in the insert fixing mold 8. The fixing bracket 17 at the bottom of the first mold 1 is connected to the output end of the external hydraulic cylinder. The fixing bracket 17 and the first mold 1 are moved and adjusted as a whole by the hydraulic cylinder. The first mold 1 and the second mold 2 are closed. Molten metal is injected into the first gating channel 4 and the second gating channel 5 through the gating pipe 3. After forming in the first mold 1 and the second mold 2, the first mold 1 moves away from the side of the second mold 2. The output end of the cylinder 18 drives the inner sliding top plate 11 to slide inside the first mold 1. The inner sliding top plate 11 carries... The first ejector pin 9 and the second ejector pin 10 move, and the second ejector pin 10 pushes the insert fixing mold 8. The insert fixing mold 8 moves synchronously to limit the placement of the insert inside. At the same time, the first ejector pin 9 pushes the formed metal pot on the first mold 1 to remove the insert from the insert fixing mold 8, thereby removing the formed metal pot and the fixed insert as a whole. When the inner sliding top plate 11 moves, it drives the inner outer sliding box 14 to move. The outer sliding box 14 slides to a limit outside the fixing plate 15. The spring 16 in the outer sliding box 14 buffers the movement of the outer sliding box 14 and the inner sliding top plate 11.

[0029] In one embodiment, such as Figure 2 and Figure 6 As shown, the buffer assembly includes an outer sliding box 14, which is symmetrically fixed inside the inner sliding top plate 11. A fixing plate 15 is slidably arranged inside the outer sliding box 14, and the top of the fixing plate 15 is fixedly connected to the first mold 1. Springs 16 are symmetrically arranged inside the outer sliding box 14.

[0030] It should be noted that in this embodiment, the spring 16 buffers the movement between the outer sliding box 14 and the fixed plate 15, and also buffers the movement of the inner sliding top plate 11, the second ejector pin 10 and the first ejector pin 9.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an inner fixed support plate 12 is fixedly connected to the inner side of mold 1, a fixed bracket 17 is fixedly connected to the bottom of the inner fixed support plate 12, and a cylinder 18 is installed at the bottom of the inner fixed support plate 12. The output end of the cylinder 18 is fixedly connected to the inner sliding top plate 11.

[0032] It should be noted that in this embodiment, the fixed bracket 17 provides overall support for the inner fixed support plate 12 and the first mold 1. The fixed bracket 17 is connected to the external hydraulic cylinder equipment to facilitate the opening and closing adjustment between the first mold 1 and the second mold 2.

[0033] In one embodiment, such as Figures 1 to 3 As shown, the interior of mold 2 is provided with a pouring pipe 3, and the interior of mold 2 is provided with a first pouring channel 4, which is connected to the pouring pipe 3. The interior of mold 2 is provided with a second pouring channel 5, which is connected to the first pouring channel 4.

[0034] It should be noted that in this embodiment, the molten metal is poured through the pouring pipe 3 and enters the first pouring channel 4 and the second pouring channel 5 through the pouring pipe 3, and the forming process is completed in the first mold 1 and the second mold 2.

[0035] In one embodiment, such as Figure 6 As shown, the inner fixed support plate 12 has symmetrical openings 13 that cooperate with the outer sliding box 14.

[0036] It should be noted that in this embodiment, the outer sliding box 14 passes through the inner fixed support plate 12 through the through port 13, so that the inner sliding top plate 11 can move normally under the drive of the cylinder 18.

[0037] In one embodiment, such as Figure 2 and Figure 6 As shown, the inner sliding top plate 11 has multiple limiting posts 19 symmetrically slidably arranged inside, and the limiting posts 19 are fixedly connected to the first mold 1.

[0038] It should be noted that in this embodiment, the inner sliding top plate 11 slides to a limit outside the limiting post 19, thereby improving the adjustment stability of the inner sliding top plate 11, the first ejector pin 9, and the second ejector pin 10.

[0039] In the description of this utility model, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "side", "top", "inner", "front", "center", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
