Abstract
The utility model relates to a special hot nozzle core structure for white materials. The special hot nozzle core structure comprises a nozzle core and a flow passage, communicated with a hot nozzle body flow passage, of the nozzle core, wherein the end part of the nozzle core is provided with a pouring gate through which colorant flows out; and the pouring gate is provided with a grid which is used for dividing the pouring gate into a plurality of distributing ports. By utilizing the scheme, the problems of wiredrawing and salivation of the special hot nozzle core for white materials when colorants are extruded are solved, and the qualified rate of the product is improved.
Description
Technical field
The utility model relates to the hot runner hot mouth, relates in particular to the hot mouth mouth of a kind of TOP-TIP cored structure, particularly the special-purpose hot mouth mouth cored structure of white material.
Background technology
The injection mold that generally adopts at Injection Industry at present is hot runner plastic injection mould, it generally comprises hot mouth body, be positioned at the runner of hot mouth body interior, be positioned at the mouth core that communicates with runner of hot mouth body front end, be positioned at the heater of hot mouth body periphery, make the injection moulding materials and parts keep the molten condition runner of flowing through to extrude from the mouth body and carry out injection mo(u)lding by heater is installed at hot mouth body.
At present, for the different mouth cored structure of the normal employing of different colorants, as shown in Figure 1, the hot mouth mouth cored structure for the special use of white material comprises mouth core 1, the runner 2 that this mouth core communicates with hot mouth body runner, and the end of mouth core 1 is used for the cast gate 3 that colorant flows out.Extruding with regard to injection mo(u)lding of the convenient white material of this structure.But this structure also comes with some shortcomings: because cast gate 3 places are straightthrough port, resistance is less, so that the white material is very fast at this place's flow velocity, and colorant concentrates the aniseed stream central temperature that flows out too high, is difficult for cooling, serious wire drawing, salivation phenomenon easily occur; Wire drawing, salivation phenomenon seriously then can affect the pouring practice of next time, so that the product fraction defective of injection mo(u)lding increases.
Therefore, how addressing the above problem, is the content that the utility model will be studied.
Summary of the invention
The utility model provides a kind of white material special-purpose hot mouth mouth cored structure, and its purpose mainly is to solve the special-purpose hot mouth mouth core of existing white material wire drawing, salivation phenomenon, the problem that causes the product fraction defective to increase easily to occur when extruding colorant.
For achieving the above object, the technical solution adopted in the utility model is: the special-purpose hot mouth mouth cored structure of a kind of white material, comprise the runner that mouth core, this mouth core communicate with hot mouth body runner, and the end of mouth core is used for the cast gate that colorant flows out; Described cast gate place is provided with grid, and this grid is divided into a plurality of diffluence pass with cast gate.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described grid is one group of framework that parallel grizzly bar is made.This frame-type grid is punished into several diffluence pass with cast gate.
2, in the such scheme, described grid is a grizzly bar.This grizzly bar is punished into two diffluence pass with cast gate.
3, in the such scheme, described grid is the knife edge type grid.This knife edge type grid is divided into two in the time of can making material stream through this place.
Because the utilization of present technique art scheme, the utility model compared with prior art has following advantages:
1, because the utility model increases the knife edge type grid at the cast gate place, the framework that this knife edge type grid can be made for one group of parallel grizzly bar, also can be an independent grizzly bar, so that aniseed stream through this knife edge type grid place, is divided into two or one be divided into a plurality of material streams, the material rheology is little, expect that then stream is easier to cooling, internal and external temperature is balanced, is not prone to wire drawing, salivation phenomenon, has guaranteed the qualification rate of product.
2, the utility model is simple in structure, practical.
Description of drawings
Accompanying drawing 1 is hot mouth mouth cored structure schematic diagram in the prior art;
Accompanying drawing 2 is the utility model structural representation.
In the above accompanying drawing: 1, mouth core; 2, runner; 3, cast gate; 4, grid; 5, diffluence pass.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment:
As shown in Figure 2, the special-purpose hot mouth mouth cored structure of a kind of white material comprises the runner 2 that mouth core 1, this mouth core 1 communicate with hot mouth body runner, and the end of mouth core 1 is used for the cast gate 3 that colorant flows out; Described cast gate 3 places laterally are provided with grid 4.This grid 4 is divided into a plurality of diffluence pass 5 with cast gate 3.
This grid 4 is the knife edge type grid.Described grid 4 is one group of framework that parallel grizzly bar is made, also can an independent grizzly bar.When described grid is one group of framework that parallel grizzly bar is made, then this frame-type grid is punished into several diffluence pass 5 with cast gate 3.When described grid is a grizzly bar, then this grizzly bar is punished into two diffluence pass with cast gate 3.
Because the utility model increases the knife edge type grid at the cast gate place, the framework that this knife edge type grid can be made for one group of parallel grizzly bar, also can be an independent grizzly bar, so that aniseed stream through this knife edge type grid place, is divided into two or one be divided into a plurality of diffluence pass, flow through each diffluence pass of aniseed flows out, expect that then rheology is little, small powder stream is easier to cooling, and internal and external temperature is balanced, be not prone to wire drawing, salivation phenomenon, guaranteed the qualification rate of product.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
