Abstract
The utility model provides a plastic bottle preform structure with good molding effect. The novel die comprises a die body, the top of the die body is provided with a die end, the surface of the die body is provided with an inclined plane close to the die end, the surface of the die body is provided with plate ribs, a plate rib groove is formed in the surface of the die body and between the two plate ribs, a folding surface is correspondingly formed in the inner wall of the die body and in the inclined plane, a groove is formed in the inner wall of the die body, threads are formed in the surface of the die end, and an end body is arranged between the top of the die body and the die end. The plastic bottle preform structure with good molding effect solves the problems that the surface of the bottle preform is easy to have thickness deviation in the preheating and blowing process due to the fact that the outer wall is smooth in the conventional plastic bottle preform during blow molding, and the quality and the compression resistance of the plastic bottle are affected due to the fact that the local surface thickness of the bottle preform is too thin.
Description
Technical Field
The utility model relates to the field of plastic bottle blanks, in particular to a plastic bottle blank structure with good forming effect.
Background
The quality of bottle depends on the quality of the bottle embryo that supplies, and the bottle embryo injection moulding divides into two kinds when being long runner, and another kind is short runner, and the plastic bottle embryo is typical injection moulding processing product, and the transportation of being convenient for is mostly plastic material, and the texture is even, has good insulativity, is the plastic bottle, and the bottle embryo is general with hot runner mould shaping, and current plastic bottle embryo is when blow moulding, because usually outer wall is smooth setting, leads to bottle embryo surface's compressive capacity poor, and the bottle embryo is in the preheating blow moulding in-process, and thickness deviation appears easily on the surface of bottle embryo, and the local surface thickness of bottle embryo is too thin, influences plastic bottle's quality and compressive capacity.
Therefore, it is necessary to provide a plastic bottle preform structure with good molding effect to solve the above technical problems.
Disclosure of Invention
The utility model provides a plastic bottle preform structure with good molding effect, which solves the problems that the surface of the bottle preform is easy to have thickness deviation in the preheating and blowing process due to poor compression resistance of the surface of the bottle preform caused by smooth arrangement of the common outer wall during the blowing molding of the existing plastic bottle preform, and the quality and compression resistance of the plastic bottle are influenced due to the fact that the local surface thickness of the bottle preform is too thin.
In order to solve the technical problems, the plastic bottle preform structure with good forming effect comprises a preform, wherein the top of the preform is provided with a preform end, the surface of the preform, which is close to the preform end, is provided with an inclined plane, the surface of the preform is provided with plate ribs, and a plate rib groove is formed on the surface of the preform and between the two plate ribs;
the inner wall of the blank body is provided with a folding surface corresponding to the inclined surface, and the inner wall of the blank body is provided with a groove.
Preferably, the surface of the end of the blank is provided with threads.
Preferably, an end body is arranged between the top of the embryo body and the end part of the embryo.
Preferably, a convex ring is arranged at the bottom of the embryo body.
Preferably, the surface of the blank body is provided with a ring groove at the bottom of the inclined plane.
Compared with the related art, the plastic bottle blank structure with good molding effect has the following beneficial effects:
the utility model provides a plastic bottle preform structure with good molding effect, which is characterized in that a plate rib and a plate rib groove are formed on the surface of a preform, so that the part with high tensile strength is fed to the surface of the preform by blow molding, the overall thickness of the preform is improved, the local surface thickness of the preform is prevented from being too thin, the quality of a plastic bottle is improved, and the problems that the pressure resistance of the surface of the preform is poor, the thickness deviation of the surface of the preform easily occurs in the preheating blow molding process, the local surface thickness of the preform is too thin, and the quality and the pressure resistance of the plastic bottle are influenced are solved when the conventional plastic bottle preform is blow molded.
