In a preferred embodiment of the present invention, the top plate, the first moving plate and the second moving plate move synchronously during the mold opening.

In a preferred embodiment of the present invention, the first core is connected to the top plate through a connecting block.

In a preferred embodiment of the present invention, the second core, the insert and the first core are disposed from inside to outside.

In a preferred embodiment of the present invention, the first core is a double-layer structure.

In a preferred embodiment of the present invention, the number of the ejector plates is two.

The utility model provides a defect that exists among the background art, the utility model discloses possess following beneficial effect:

the utility model discloses a secondary ejection structure carries out ejecting operation to the product that has dark bone position and knot position structural feature, and is ejecting effectual, has guaranteed the stability of product, and the utility model discloses simple structure compares in the ejecting structure of traditional cubic, and is lower to the processing cost of mould to the life of mould has still been improved.

fig. 2 is a schematic structural view of a secondary ejection structure according to a preferred embodiment of the present invention;

fig. 3 is a cross-sectional view of a secondary ejection structure according to a preferred embodiment of the present invention;

in the figure: 1. a top plate; 2. a first motion plate; 3. a second motion plate; 4. a fixing plate; 5. a base plate; 6. a secondary ejection structure; 61. a first core; 62. an ejector plate; 63. an insert; 631. a buckling structure; 64. a second core.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

As shown in fig. 1 to 3, a mold having a double ejection structure 6 includes a top plate 1, a first moving plate 2, a second moving plate 3, a fixing plate 4 and a bottom plate 5, which are sequentially arranged from top to bottom, wherein the double ejection structure 6 includes a first core 61 located in the top plate 1 and the first moving plate 2, an ejector plate 62 located in the second moving plate 3, an insert 63 connected to the ejector plate 62, and a second core 64 whose bottom end is fixed in the fixing plate 4; the first core 61 can move synchronously with the top plate 1, a spring is arranged in the ejector plate 62, when the mold is closed, the spring has elastic potential energy, the insert 63 is positioned in the first core 61, the bottom end of the insert 63 is connected with the spring, the top end of the insert 63 is provided with a buckling structure 631, and the second core 64 penetrates through the insert 63.

In this embodiment, the bottom of the second core 64 is fixed on the fixed plate 4, after the injection molding of the product is completed, the top plate 1 drives the first moving plate 2 and the second moving plate 3 to move synchronously, at this time, the ejector plate 62, the insert 63 and the first core 61 all move upward to be separated from the second core 64, after a certain stroke, the first ejection operation is completed, then, the first moving plate 2 and the second moving plate 3 are fixed, and the top plate 1 continues to open the mold upward, at this time, because the spring in the ejector plate 62 has elastic potential energy, the elastic potential energy stored in the spring is released during the movement of the top plate 1, so the insert 63 is driven to move, and the insert 63 is ejected from the first core 61, meanwhile, the product is separated from the buckling structure 631 on the top of the insert 63, and during the second ejection operation, the tripping operation of the product is completed synchronously, no third ejection is required.

Specifically, when the mold is opened, the external injection molding machine drives the top plate 1, the first moving plate 2 and the second moving plate 3 to move synchronously.

Further, the first mold core 61 is connected with the top plate 1 through a connecting block, so that the top plate 1 can drive the first mold core 61 to move synchronously in the moving process.

Specifically, the second core 64, the insert 63, and the first core 61 are disposed from the inside to the outside.

Further, the first core 61 is a two-layer structure.

Specifically, the ejector plate 62 is two in number.

To sum up, the utility model discloses a secondary ejection structure 6 carries out ejecting operation to the product that has dark bone position and knot position structure 631 characteristics, and is ejecting effectual, has guaranteed the stability of product, and the utility model discloses simple structure compares in traditional cubic ejection structure, and is lower to the processing cost of mould to the life of mould has still been improved.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
