[ detailed description ] embodiments
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 5. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-5, the utility model provides a demoulding structure with a slant top on a slant extraction, which comprises a slant extraction fixing plate 5 and an ejector plate 14 arranged on a rear mould 6, and a slant top 9 and a slant extraction 10 arranged on a B plate 3. The periphery of the rear mold 6 is provided with mold feet 13, and a first equal-height screw 12 arranged in the mold feet 13 is used for connecting the inclined drawing fixing plate 5 with the B plate 3. And return spring accommodating holes are respectively formed in the positions, corresponding to the first equal-height screws 12, of the joint of the inclined drawing fixing plate 5 and the B plate 3, and the first return springs 4 penetrate through the first equal-height screws 12 and are arranged in the return spring accommodating holes.
