Abstract
The utility model relates to a surface shrinkage prevention structure which is applied to a plastic mould. The mould comprises a panel, a movable mould, a fixed mould and a bottom plate, wherein the fixed mould is internally provided with a rear mould embedding needle. The mould is characterized in that the surface shrinkage prevention structure is arranged at the top of the rear mould embedding needle to be suspended at the bottom of a product; the surface shrinkage prevention structure comprises a central cylinder, a reinforcing rib and a supporting plate; the central cylinder is arranged on the supporting plate; the reinforcing rib is arranged on the outer wall surface of the central cylinder and the bottom of the reinforcing rib is connected with the supporting plate; the top of the supporting plate is connected with a connection rod. The utility model aims to provide a structure which is simple in structure and has no shrinkage traces on the surface so that the appearance of a plastic product is beautiful and the surface of the product is prevented from shrinking.
Description
[technical field]
The utility model relates to a kind of plastic cement products structure, relates in particular to a kind of anti-surperficial shrink structure.
[background technology]
It is its intrinsic characteristic that plastic cement shrinks, product is easy to occur shrink phenomenon after depanning owing to expanding with heat and contract with cold, in order to prevent that product surface from shrinking, there is indenture at present, in product bottom, anti-surperficial shrink structure is set, shrink structure is typically provided to cylindrical, but can leave indenture, when indenture is stayed product surface, affect very much attractive in appearance.
[utility model content]
In order to overcome the above-mentioned deficiency of existing toilet lid mould, the utility model provides a kind of anti-surperficial shrink structure that makes product not stay indenture.
The utility model solves the technical scheme that its technical problem adopts: a kind of anti-surperficial shrink structure, anti-shrinkage structure is located in mould, mould comprises panel, dynamic model, cover half and base plate, in cover half, be provided with rear mold pin, it is characterized in that: it is unsettled in product bottom that described anti-shrinkage structure is located at rear mold pin top, anti-shrinkage structure comprises centered cylinder, ribs and gripper shoe, centered cylinder is located in gripper shoe, ribs is located at centered cylinder outside wall surface, bottom is connected with gripper shoe, and described gripper shoe top is connected with connecting rod.
Further, described gripper shoe is U-shaped plate.
Further, described connecting rod is A-frame, and three angles of support are connected with product respectively.
The beneficial effects of the utility model are: anti-shrinkage structure is arranged on to product bottom unsettled, make to shrink structure and product contact-making surface diminish, and during depanning, product surface there will not be shrink trace, and product design is attractive in appearance.
[accompanying drawing explanation]
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local cross-sectional view of amplifying of the utility model;
Structural representation when Fig. 3 is the utility model use.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
The utility model is in conjunction with Fig. 1-3, a kind of anti-surperficial shrink structure, anti-shrinkage structure 1 is located in mould, mould comprises panel 2, dynamic model 3, cover half 4 and base plate 5, in cover half 4, be provided with rear mold pin 6, it is characterized in that: it is unsettled in product 7 bottoms that described anti-shrinkage structure 1 is located at rear mold pin 6 tops, anti-shrinkage structure 1 comprises centered cylinder 11, ribs 12 and gripper shoe 13, centered cylinder 11 is located in gripper shoe 13, ribs 12 is located at centered cylinder 11 outside wall surface, bottom is connected with gripper shoe 13, and described gripper shoe 13 tops are connected with connecting rod 14.
Gripper shoe 13 is U-shaped plate centre of support cylinder 11 and ribs 12..
Connecting rod 14 is A-frame 15, and three angles of support are connected with product 7 respectively.
Anti-shrinkage structure of the present utility model, has reduced contact area, has guaranteed that product surface does not have shrink trace, good looking appearance, and anti-shrinkage structure of the present utility model is simple in structure, convenient for production, can be applied to various injection molds.
For clearer, complete description content of the present invention, provide several width the accompanying drawing that the present invention conceives can be described below.Certainly, the accompanying drawing providing is intended to illustrate design of the present invention, is not the whole of design of the present invention, more should be considered as the limitation of design content of the present invention.Under the enlightenment of provided accompanying drawing, any scheme of having done all belongs to protection scope of the present invention.
