Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As shown in figure 3, in a specific embodiment, the closed type extrusion molding dies that bulb three provided by the invention is sold
It can be moved up and down including upper mold 101 and the lower die 106 being arranged immediately below the upper mold 101, the upper mold 101, downwards
It can fit with the lower die 106 when mobile.
The top of the upper mold 101 is equipped with upper pilot hole 102, and the lower part of the upper mold 101 is equipped with and the upper pilot hole
The upper cavities 103 of 102 connections are formed on the inner wall of the upper cavity 103 there are three upper groove 104, each upper groove 104 with
It is connected to through bleeder port 105 on one between the upper pilot hole 102.Columned upper punching is equipped in the upper pilot hole 102
Head (not shown), the upper punch can be moved up and down along the upper pilot hole 102, and the upper mold can be entered when moving down
In chamber 103.The diameter for the groove on upper surface that the diameter of the upper punch is sold with molding bulb three to be extruded matches.
The lower part of the lower die 106 is equipped with lower pilot hole 107, and the top of the lower die 106 is equipped with and the lower pilot hole
The lower mode cavities 108 of 107 connections, form that there are three matched with three upper grooves 104 on the inner wall of the lower mode cavity 108
Lower groove 109 is connected to through bleeder port 110 once between each lower groove 109 and the lower pilot hole 107.It is led under described
Columned low punch (not shown) is equipped with into hole 107, the low punch can move down on the lower pilot hole 107
It is dynamic, it can enter in the lower mode cavity 108 when moving up.The diameter of the low punch and molding bulb three to be extruded pin
The diameter of groove on lower face matches.
When the upper mold 101, which is moved downward to, to fit with the lower die 106, the upper cavity 103 and the lower die
Chamber 108 is closed and is encircled into the extrusion die cavity that the shape sold with bulb to be formed three and size match.
Shown in Fig. 4, the operation principle for the closed type extrusion molding dies that bulb three provided by the invention is sold
It is as follows：
(1), original state：Upper mold 101 is separated from each other with lower die 106, upper punch along upper pilot hole 102 be moved downward to
It is flushed at the lower ending opening of upper pilot hole 102, low punch is moved upward to be flushed at the upper end opening of lower pilot hole 107.
(2), will bulb three sell blank 300 merging lower mode cavity 108 in, then control upper mold 101 move down until with
Bulb three is sold blank 300 and is contacted.
(3), upper mold 101 continues traveling downwardly the pin blank 300 of squeeze bulb three, until upper mold 101 is bonded shape completely with lower die 106
At complete extrusion die cavity.
(4), upper punch, low punch separately down, upward bulb three sell the middle part of blank 300, in extrusion process, squeeze
Air in compression mold cavities is discharged through three upper bleeder ports 105 and three lower bleeder ports 110, so that bulb three is sold
The material at 300 middle part of blank can be sufficiently flowed into the upper groove 104 and the lower groove 109 to both sides.
As it can be seen that the closed type extrusion molding dies that bulb three proposed by the present invention is sold, equal shape in upper cavity and lower mode cavity
At there is bleeder port.Bulb three sells blank during extrusion forming, and the air in extrusion die cavity can in time be discharged through bleeder port,
So that the material in blank can fully flow and be full of extrusion die cavity, the formed precision that bulb three is sold finally ensure that.
The key of the present invention is to improve the design accuracy of upper cavity and lower mode cavity so that upper cavity and lower mode cavity are closed to be formed
The extrusion die cavity and the shape sold of bulb three to be formed and size match.Particularly, the shape and size of upper groove
The shape and size on the top for the bulb sold with bulb three are mutually matched, the bulb of the shape and size and the pin of bulb three of lower groove
Lower part shape and size be mutually matched.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in fields
Personnel are it should be understood that the description in embodiment is only exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change should all belong to the scope of protection of the present invention.Scope of the present invention is by the power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
