Abstract
The invention provides a terrazzo PVC dividing strip die. The cross sections of a die body cavity, a bracket plate cavity and a confluence plate cavity are arranged into dumbbell-shaped cavities with thin middle parts and thick two ends; in addition, the size of the confluence plate cavity gradually decreases according to the flowing direction of fluid, so that on one hand, fluid is more uniformly distributed before forming, and the density distribution after forming is more uniform, on the other hand, the fluid pressure is enabled to be more concentrated, and the strength after forming is high; moreover, with adoption of the PVC material, the manufacturing cost of a terrazzo dividing strip can be reduced.
Description
Technical field
The present invention relates to extruded grinding tool, particularly relate to a kind of terrazzo PVC divider mould.
Background technology
Waterstone separating strip generally adopt metal material suppress or casting form, its manufacturing cost higher and distortion after not easily recover.Therefore have the Waterstone separating strip of plastic material at present on the market, but its shaping strength is inadequate, even density, easily ruptures.
Summary of the invention
In view of this, the object of the invention is: for the deficiencies in the prior art, a kind of high strength, Density Distribution uniform terrazzo PVC divider mould is provided.
In order to achieve the above object, the technical solution used in the present invention is: a kind of terrazzo PVC divider mould, it comprises the die body be cascading from bottom to up, supporting plate, cylinder manifold, second mouthful of mould and first mould, and be correspondingly arranged on die body, supporting plate, cylinder manifold, on second mouthful of mould and first mould, and according to the die body cavity of fluid circulating direction successively UNICOM, supporting plate cavity, cylinder manifold cavity, second mouthful of mould cavity and first mould cavity, described die body cavity, supporting plate cavity, cylinder manifold cavity, second mouthful of mould cavity and first mould cavity cross section are middle thin, the dumbbell shaped cavity that two ends are thick, and described cylinder manifold cavity size diminishes gradually according to fluid circulating direction.
The invention has the beneficial effects as follows: terrazzo PVC divider mould provided by the invention is by being set to die body cavity, supporting plate cavity, cylinder manifold cavity cross section the dumbbell shaped cavity that centre is thin, two ends are thick, and described cylinder manifold cavity size diminishes gradually according to fluid circulating direction, fluid can be made to be more evenly distributed before the forming on the one hand, therefore shaping rear Density Distribution is more even; Fluid pressure can be made more concentrated on the other hand, therefore shaping rear intensity is higher; The third aspect, by adopting PVC material, can reduce Waterstone separating strip manufacturing cost.

Detailed description of the invention
Shown in Fig. 1 ~ 5, terrazzo PVC divider mould of the present invention, it comprises the die body 1 be cascading from bottom to up, supporting plate 2, cylinder manifold 3, second mouthful of mould 4 and first mould 5, and be correspondingly arranged on die body 1, supporting plate 2, cylinder manifold 3, on second mouthful of mould 4 and first mould 5, and according to the die body cavity 11 of fluid circulating direction successively UNICOM, supporting plate cavity 21, cylinder manifold cavity 31, second mouthful of mould cavity 41 and first mould cavity 51, described die body cavity 11, supporting plate cavity 21, cylinder manifold cavity 31, second mouthful of mould cavity 41 and first mould cavity 51 cross section are middle thin, the dumbbell shaped cavity that two ends are thick, and described cylinder manifold cavity 31 size diminishes gradually according to fluid circulating direction.
As to a modification of the present invention, described supporting plate cavity 21, cylinder manifold cavity 31, second mouthful of mould cavity 41 and first mould cavity 51 are respectively arranged with two, and are arranged symmetrically with along terrazzo PVC divider mold center direction of principal axis.So, extruded two Waterstone separating strips of feed, enhance productivity and mould utilization rate.Further, described die body cavity 11 is provided with two supporting plate cavities 21 described in an opening 12 and two outlets, 13, two outlet 13 corresponding UNICOMs.
As to a modification of the present invention, described first mould cavity 51 comprises the first middle interconnecting piece 511 that cross section is rectangle, and cross section is the first trapezoidal load receiving part 512, and cross section is the first head 513 of rectangle.Further, described second mouthful of mould cavity 41 comprises the second middle interconnecting piece 411 that cross section is rectangle, and cross section is the second trapezoidal load receiving part 412, cross section is the second head 413 of rectangle, and described second load receiving part 412 is provided with groove 414 away from the end face of the second middle interconnecting piece 411.So, can prevent shaping after the outside warpage of terrazzo PVC divider load receiving part.
Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
