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 rear mold lifter structure of an injection mold comprises a rear mold plate 1, an upper mold core 2 located above the rear mold plate 1, and an ejection structure 3 for ejection; be provided with roof 4 on the back template 1, go up the mould benevolence 2 and be provided with mould insert 5 in, ejecting structure 3 includes fixed block 31 and the oblique kicking block 32 that is located on fixed block 31, and fixed block 31 is located roof 4, and oblique kicking block 32 corresponds with last mould insert 5 position, and oblique kicking block 32 top is equipped with oblique top notch 6.
In this embodiment, the product is by last mould insert 5 and last mould benevolence 2 cooperation injection moulding, and after the product shaping, roof 4 rises, drives the oblique kicking block 32 of ejecting structure 3 and rises, and the existence of oblique top notch 6 can cooperate with last mould insert 5, realizes the shaping to the product, and when oblique kicking block 32 was ejecting with the product, oblique top notch 6 can cooperate with the product, makes the product ejecting smoothly, can not appear damaging.
Specifically, in this embodiment, the angle between the slanted ejecting block 32 and the vertical line is 15 degrees, which ensures smooth ejection.
In the present embodiment, the number of the top plates 4 is two.
Further, the top plate 4 is provided with a positioning pin 7.
In this embodiment, the number of the ejection structures 3 is two, and two products can be ejected simultaneously.
Specifically, a clamping groove is formed in the top end of the fixing block 31, and the bottom of the inclined ejecting block 32 is located in the clamping groove.
To sum up, the utility model discloses under the mating reaction of back template 1, last mould benevolence 2 and ejecting structure 3, realized that the slant to the product is ejecting, to the product that the profile has the radian, the slant is ejecting can not cause the damage of product, has realized ejecting safely to the product, has guaranteed the injection moulding quality of product.
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.
