AI Technical Summary
When the product undercut on the front mold side of a large mold needs to be ejected by a slanted ejector, conventional slanted ejectors require large ejector plates, resulting in a large mold size and high cost.
The U-shaped inclined ejector mechanism includes a front mold insert, a U-shaped inclined ejector, a spring component, and a pull hook. One end of the U-shaped inclined ejector is fixed to the rear mold, and the other end is connected to the product undercut. The spring component uses its elasticity to eject the product when the rear mold is separated from the front mold, and the pull hook assists in core pulling, avoiding the use of ejector plates and reset rods.
This has enabled miniaturized mold design, reduced mold costs, improved core-pulling efficiency and quality, and simplified the operation process.

[0004] The utility model discloses the following scheme:
[0005] A practical simple front mould U shape inclined top mechanism, it is suitable for installing between front mould and rear mould, include: front mould insert, U shape inclined top, spring piece and draw hook, wherein, one end of U shape inclined top is fixedly connected on rear mould, and the other end is connected to the reverse buckle of product, spring piece sets up in U shape inclined top, and it is configured as can when rear mould is separated from front mould, utilize its elastic force and eject U shape inclined top to realize core pulling at reverse buckle, draw hook connects rear mould with U shape inclined top.
[0006] Further, the U-shaped inclined top includes a main body portion and a core pulling portion having the same inclination, and the main body portion is connected to the rear mold.
[0007] Further, a spring groove is formed in the main body portion, and the spring member is disposed in the spring groove.
[0008] Further, a step portion is provided on one side of the main body portion, and the draw hook is partially connected to the step portion.
[0009] Further, a limiting member is provided on the top of the front mold insert to compress the spring member in the spring groove, and the limiting member is connected to the front mold.
[0010] Further, the main body portion is installed in an installation groove of the rear mold, and a wear-resistant sheet is provided in the installation groove.
[0011] Beneficial effects:
[0012] The scheme sets the U-shaped inclined top on the front mold and the rear mold, and the U-shaped inclined top is pulled out along the gradient direction under the action of the spring member pull hook when the mold is opened, and the undercut core pulling is completed. The U-shaped structure inclined top does not need the ejector plate and the reset rod, and only occupies a small space. In addition, the pull hook also pulls the inclined top when the mold is opened, ensuring that there is enough force to make the inclined top pop out at the moment of mold opening. When resetting, the spring is compressed by the non-rubber position of the U-shaped inclined top. The structure is simple and convenient to operate, which is beneficial to reduce the mold cost.

DETAILED DESCRIPTION
[0018] Combined Figures 1 to 4 As shown in the drawings, the embodiment provides a mold, which comprises a front mold 1 and a rear mold 2, and further comprises a practical simple front mold U-shaped inclined mechanism. The practical simple front mold U-shaped inclined mechanism is adapted to be installed between the front mold 1 and the rear mold 2, and comprises a front mold insert 4, a U-shaped inclined top 3, a spring member 5 and a pull hook 6. One end of the U-shaped inclined top 3 is fixedly connected to the rear mold 2, and the other end is connected into an undercut 71 of a product 7. The spring member 5 is arranged in the U-shaped inclined top 3, and is configured to use the elastic force to eject the U-shaped inclined top 3 to realize core pulling at the undercut 71 when the rear mold 2 is separated from the front mold 1. The pull hook 6 is connected to the rear mold 2 and the U-shaped inclined top 3.
[0019] Combined Figures 2 to 4As shown in the embodiment, the U-shaped draft 3 includes a main body 31 and a core-pulling part 33 with the same inclination, and the main body 31 is connected to the back mold 2. A spring groove is formed in the main body 31, and the spring member 5 is arranged in the spring groove. Here, the U-shaped draft 3 is arranged to be inclined at an angle of 10°, and the main body 31 and the core-pulling part 33 have the same inclination angle. A step part 32 is arranged on one side of the main body 31, and the pull hook 6 is partially connected to the step part 32. The pull hook 6 can cooperate with the spring member 5 to pull out the U-shaped draft 3 during demolding, thereby assisting in core pulling. It should be noted that the pull hook 6 is only partially overlapped on the step part 32, and the overlapping part is close to one side of the inverted buckle 71 of the product 7, so that the U-shaped draft 3 can be pulled out from the inverted buckle 71 of the product 7 to realize core pulling.
