Abstract
The invention relates to a variable-length intake manifold roller-type switching valve and a method for forming a valve core thereof. A structural form is that: the valve core positioned in a pipeline of an intake manifold main body is a roller capable of rotating around a fixed axis; an overflowing through hole is formed on the roller and along the direction vertical to a central axis of the roller; an inlet, which is connected with the overflowing through hole on the roller, of the pipeline of the intake manifold main body is in an open state; and the forming method is characterized in that: the roller takes an injection molding main body as a framework and an elastomer skin is formed on a surface layer of the injection molding main body in a secondary injection molding mode. The valve core can form a good matching relationship with a cavity, so that the performance of an engine is improved.
Description
Technical field
The present invention relates to engine accessory power rating, more specifically the say so a kind of roller-type switching valve of engine variable length intake manifold and the forming method of spool thereof.
Background technique
The structural type of the roller-type switching valve of the engine variable length plastic air intake manifold of existing use is shown in Fig. 2 a and Fig. 2 b, but be positioned at the ducted spool of intake manifold body is a dead axle rotary drum, on the cylinder, on the direction perpendicular to the cylinder axis opening was set; Cylinder is an opening state with the inlet that the opening excessively on it is undertaken on intake manifold body pipeline.But in concrete the application, there is a problem in this roller-type switching valve, plastic drum produces distortion inevitably in injection molding process, jam when distortion can cause roller-type switching valve to rotate on the one hand, on the other hand because distortion causes the slit between cylinder and cavity, gas-blowing phenomenon when causing shutoff reduces engine performance.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology deficiency, the forming method of a kind of variable-length intake manifold roller-type switching valve and spool thereof is provided, make the suitable matching relationship of maintenance between roller-type switching valve and the cavity with its specific structural type, guarantee to rotate smooth and easy, also avoid simultaneously between cylinder and cavity, producing the slit and causing gas blowby, in the hope of the raising engine performance.
The technological scheme that technical solution problem of the present invention is adopted is:
The structural type of variable-length intake manifold roller-type switching valve of the present invention is but that to be positioned at the ducted spool of intake manifold body be a dead axle rotary drum, on the described cylinder, on the direction perpendicular to the cylinder axis opening was set; Described cylinder with on it to cross the inlet that opening is undertaken on described intake manifold body pipeline be opening state, its structural feature is that described cylinder is to be skeleton with the injection moulding body, the mode on the top layer of described injection moulding body with quadric injection mould forms elastomer skin.
The forming method of the spool of variable-length intake manifold roller-type switching valve of the present invention is characterized in adopting the mode of quadric injection mould, and the injection moulding first time in the described quadric injection mould forms the injection moulding body of described cylinder; Treat described injection moulding body be out of shape naturally stable after, injection moulding forms elastomer skin once more on the surface of described injection moulding body.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention has eliminated the deformation defect of conventional plastic roller-type switching valve, makes to have obtained good matching relationship between roller-type switching valve and the cavity, has effectively improved engine performance.

Number in the figure: 1 injection moulding body, 2 elastomer skins.
Embodiment
Referring to Fig. 1 a and Fig. 1 b, the structural type of the variable-length intake manifold roller-type switching valve in the present embodiment is but that to be positioned at the ducted spool of intake manifold body be a dead axle rotary drum, on the cylinder, on the direction perpendicular to the cylinder axis opening was set; Cylinder is opening state (shown in Fig. 1 a) with the inlet that the opening excessively on it is undertaken on described intake manifold body pipeline
In the present embodiment, cylinder is to be skeleton with injection moulding body 1, and the mode on the top layer of injection moulding body 1 with quadric injection mould forms elastomer skin 2.
Present embodiment can specifically be finished the moulding of spool in the following manner:
At first adopt the traditional injection moulding method, put into the antero posterior axis of cylinder in a mould, can adopt the injection moulding body 1 of PA6-GF30 material molding and forming cylinder, injection moulding body 1 is slightly less than the external diameter of cylinder on diameter;
From a mould, take out injection moulding body 1, lie in a horizontal plane in and carry out ageing treatment on the flat board;
Through ageing treatment after a while, injection moulding body 1 is put into mould with injection moulding body 1 No. two as skeleton after fully being out of shape, and carries out quadric injection mould with elastic material, and the purpose of quadric injection mould is on the drum surface of injection moulding body 1, covers one deck elasticity epidermis 2.Because the distortion of injection moulding body 1 is stable, the surface of injection moulding body 1 once more injection moulding to form the thickness of elastomer skin 2 itself very thin, be unlikely to spur body and produce distortion, compensate, obtain the highi degree of accuracy roller-type switching valve with this with the distortion of 2 pairs of injection moulding bodies 1 of elastomer skin.
Claims (2)
1. variable-length intake manifold roller-type switching valve, but its structural type is that to be positioned at the ducted spool of intake manifold body be a dead axle rotary drum, on the described cylinder, on direction, opening was set perpendicular to the cylinder axis; Described cylinder is an opening state with the inlet that the opening excessively on it is undertaken on described intake manifold body pipeline, the described cylinder of its feature is to be skeleton with injection moulding body (1), and the mode on the top layer of described injection moulding body (1) with quadric injection mould forms elastomer skin (2).
2. the forming method of spool in the described variable-length intake manifold roller-type switching valve of claim 1 is characterized in that adopting the mode of quadric injection mould, and the injection moulding first time in the described quadric injection mould forms the injection moulding body (1) of described cylinder; Treat described injection moulding body (1) be out of shape naturally stable after, injection moulding forms elastomer skin (2) once more on the surface of described injection moulding body (1).
