Abstract
The utility model specifically discloses a kind of oil pressure needle valve hot flow passage device, comprises body and the main burner be fixed on described body and a cylinder body; With the upper strata flow distribution plate of described main burner UNICOM, described upper strata flow distribution plate is fixed by centralized positioning pin, is fixed with the oblique flow distribution plate of lower floor below the flow distribution plate of described upper strata; Described cylinder body is connected with hot nozzle, and the oblique flow distribution plate of described lower floor is connected with described hot nozzle.It is by adjustment manifold structure, make nozzle of hot-runner system and mould can shape at an angle, accomplish that hot-runner nozzle tiltedly enters glue.
Description
Technical field
The utility model is specifically related to a kind of oil pressure needle valve hot flow passage device.
Background technology
Common TOP-TIP only has vertical direction to enter glue, and namely TOP-TIP can not with tapering, and it is vertical mold template that hot-runner nozzle enters glue direction, vertical with injection machine gun barrel direction.Needle-valve system is the same, can only be that glue is entered in 90 ° of directions.But in order to reduce the energy, increasing part have employed plastics usher into go substitute before traditional metal or other part, therefore also result in increasing plastic items and can not carry out injection moulding with common TOP-TIP, cold runner system can only be used after conventional TOP-TIP can not use, a lot of raw-material loss can be caused like this, and molding cycle can be elongated, for product, also can cause a lot of defect, more some plastic cement products just can not injection moulding by cold runner.
In addition, conventional TOP-TIP be make product outward from mold center enter glue point, glue is entered to product.Now, what promote that needle carries out moving is mounted in cylinder on mould or oil cylinder, because TOP-TIP is be in a heated condition when actual production always, therefore, must give around cover half fixed head cylinder body and walk cooling water channel, i.e. deep hole processing on stationary mould for mould fixed head, and form loop, be reached for its cooling effect, prevent sealing ring from damaging.In order to make the piston up-down in cylinder body, must give in cylinder body and be filled with gas or oil, therefore, the cover half fixed head of mould needs process gas circuit/oil circuit, to cylinder/oil cylinder power, make piston up-down, promotion needle reaches a sealing effect to injecting products, and this gas circuit/oil circuit equally also needs to process on mould upper mounted plate.
The shortcoming of this structure is, when enter the glue point distance of positions from mold center's (being main nozzle position under normal circumstances) distance L value too away from time, the thermal expansion produced during system actual production can be excessive, causes needle can not load in mould smoothly when cold conditions, cause and can not produce smoothly.
Need the cooling water channel processed and gas circuit/oil circuit processing time consuming effort above mould upper mounted plate, especially hot flow path enter glue point position more time, the water route on mould and gas circuit/oil circuit comparatively complicated, easily make mistakes when follow-up mould pincers worker is assembled.
All parts in system are split type, need single part progressively to install, expend time in during installation, and easily cause Lou glue equivalent risk when installation portion puts in place.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, there is provided one can pass through adjustment manifold structure, make nozzle of hot-runner system and mould can shape at an angle, accomplish that hot-runner nozzle tiltedly enters the oil pressure needle valve hot flow passage device of glue.
The utility model solves the technical scheme that its technical problem adopts: a kind of oil pressure needle valve hot flow passage device, comprises body and the main burner that is fixed on described body and a cylinder body; With the upper strata flow distribution plate of described main burner UNICOM, described upper strata flow distribution plate is fixed by centralized positioning pin, is fixed with the oblique flow distribution plate of lower floor below the flow distribution plate of described upper strata; Described cylinder body is connected with hot nozzle, and the oblique flow distribution plate of described lower floor is connected with described hot nozzle.
As the further optimization of technique scheme, described cylinder body is provided with cylinder cap, and cylinder cap is provided with perforate, is equipped with piston in described perforate.
The beneficial effects of the utility model:
1. because each block of lower floor's flow distribution plate is all that separately independently therefore guard system does not have much, all can not produce produce because thermal expansion is excessive can not installation question.
2., by the prepackage in system to cylinder body and hot nozzle, all winding displacements on lower floor's flow distribution plate and Teflon pipe are all the objects reaching the saving system set-up time be pre-installed.Mould upper mounted plate need not process cooling water channel gentle/oil circuit, saving Mould Machining time, reduction Mould Machining precision.
3. oblique nozzle can be installed and injection moulding.Accurate positioning is convenient.
4. by adjustment manifold structure, make nozzle of hot-runner system and mould can shape at an angle, accomplish that hot-runner nozzle tiltedly enters glue.

Fig. 2 is the longitudinal profile structural representation of a kind of oil pressure needle valve hot of the utility model flow passage device.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model detailed description of the invention is described:
Fig. 1-2 shows a kind of detailed description of the invention of the present utility model, and as shown in FIG., a kind of oil pressure needle valve hot of the utility model flow passage device, comprises body and be fixed on main burner 1 and the cylinder body 4 on described body; Also comprise the upper strata flow distribution plate 2 with described main burner 1 UNICOM, described upper strata flow distribution plate 2 is fixed by centralized positioning pin, is fixed with the oblique flow distribution plate 3 of lower floor below described upper strata flow distribution plate 2; Described cylinder body 4 is connected with hot nozzle 5, and the oblique flow distribution plate of described lower floor 3 is connected with described hot nozzle 5.
Described cylinder body 4 is provided with cylinder cap, and cylinder cap is provided with perforate, is equipped with piston in described perforate.
The utility model is in the specific implementation:
Plastic cement melt enters upper strata flow distribution plate 2 by main nozzle 1, and upper strata flow distribution plate 2 is by centralized positioning finger setting, and center cushion block and upper cushion block support.Plastic cement melt enters in hot nozzle 5 after entering lower floor's flow distribution plate 3 by the connector in the oblique flow distribution plate 3 of upper strata flow distribution plate 2 and lower floor, promoting needle and to move up and down the filling that reaches plastic cement and the action of envelope pin, filling plastic cement products by being contained in cylinder body 4 in advance.
By reference to the accompanying drawings the utility model preferred embodiment is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
