Abstract

The invention relates to a staggered branching structure of a bracket plate for a plastic extrusion tubing mold. The staggered branching structure consists of an outer ring, an inn ring and a connecting structure connecting the rings together, wherein the connecting structure adopts a staggered branching structure formed by upper and lower staggered rhombuses or rectangles. The invention has the benefits that the staggered branching structure of the bracket plate can perform staggered branching on plastic blank flowing through a bracket runner, so as to disturb the flow direction, effectively reduce the bracket trace of plastic tubing, improve the comprehensive physical property of the tubing, and reduce the rejection rate of the tubing.

Description

A kind of plastics extruding pipe material mould rack plate flow dividing structure that interlocks
Technical field
The present invention relates to the plastics extruding pipe material, especially a kind of plastics extruding pipe material mould rack plate flow dividing structure that interlocks.
Background technology
The supporting plate that uses on the existing plastics extruding pipe material mould, the syndeton of its outer ring and inner ring can be cut shunting by force with the plastics blank that enters the support runner, causes the finished product pipe material inner wall to leave than ramus profundus frame trace, has a strong impact on the comprehensive physical property of tubing.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of staggered flow dividing structure of plastics extruding pipe material mould rack plate of effective minimizing support trace is provided.
The present invention solves the technical scheme that its technical problem adopts: this plastics extruding pipe material mould rack plate flow dividing structure that interlocks, form the staggered flow dividing structure that described syndeton is staggered to form for two rhombuses or rectangular block up and down by outer ring, inner ring and the syndeton that is connected them.
As preferably, described syndeton has four distributions that are centrosymmetric at least, is preferably six.
The effect that the present invention is useful is: the shunting that the plastics blank of the support runner of flowing through can be interlocked of the staggered flow dividing structure of this supporting plate, upset its flow direction, thereby can effectively reduce the generation of plastic pipe support trace, thereby improve the comprehensive physical property of tubing, reduce the tubing scrappage.

Fig. 3 is the existing structure schematic diagram;
Fig. 4 is a syndeton enlarged drawing in the existing structure;
Fig. 5 is an assembling schematic diagram of the present invention;
Description of reference numerals: mouthful mould 1, plug 2, die holder 3, supporting plate 4, outer ring 4-1, inner ring 4-2, syndeton 4-3 divides flow cone 5, runner 6, charging aperture 7.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment: as shown in Figure 1, 2, this supporting plate 4 is made up of with the syndeton 4-3 that is connected them outer ring 4-1, inner ring 4-2, and syndeton 4-3 is two staggered flow dividing structures that diamond block is staggered to form up and down, has six and is central distribution.
As shown in Figure 5, plastics extruding pipe material mould comprises the mouth mould 1 and the inner plug 2 of front end periphery, the die holder 3 of rear perpheral and inner branch flow cone 5, be provided with runner 6 between mouth mould 1 and the plug 2 and between die holder 3 and the branch flow cone 5, the die holder rear is a charging aperture 7, and blank enters from charging aperture 7, through dividing the shunting of flow cone 5, the whole runner 6 of flowing through, through port mould 1 is formed into product tubing.Among, supporting plate 4 civilian dresses are between die holder 3 and branch flow cone 5, and outer ring 4-1 is used for fixing die holder 3, and inner ring 4-2 is used for fixing branch flow cone 5, and its syndeton 4-3 is arranged in runner 6.
Shown in Fig. 3,4, when the blank existing syndeton of flowing through, it is walked around from the syndeton both sides, converges in the place ahead again, flows to more regularly, finally can cause the finished product pipe material inner wall to leave darker support trace.And, make it flow to become comparatively irregular, the generation of the minimizing plastic pipe support trace that can purchase and sell when the blank staggered flow dividing structure of the present invention of flowing through.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
