Background technology
A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected in the die cavity of injection mold by high pressure by concrete finger, after cooling curing, obtains formed products.
Existing injection mold, when injection mo(u)lding, needs to be closed by upper and lower mould in advance, then by injection hole to injection moulding melt plastic cement in die cavity.When upper and lower mould closes, in order to ensure upper and lower mould closure accuracy, generally corresponding positioning guide column and detent are set respectively on upper and lower mould, and the structure of positioning guide column and detent and the impact of set-up mode on the closure accuracy of upper and lower mould most important.
In addition; existing injection mold often there will be mould filling deficiency in injection moulding process; the air retained is compressed the compressed-air actuated situation of rear formation high temperature; die cavity is vented bad meeting and causes the problem such as goods and product surface streamline, focal spot of burning; corresponding vacuum extractor generally can be set and be communicated to die cavity to be discharged by mould intracavity gas in time; but when vacuumizing, often can be bad and cause vacuumizing effect poor due to upper and lower mould closing face sealing property.
Utility model content
The utility model proposes the injection mold that high leakproofness is easy to closed upper and lower mould, its object is intended to overcome prior art above shortcomings, realizes upper and lower mould high accuracy and closes and closing face good seal performance.
Technical solution of the present utility model: high leakproofness is easy to the injection mold of closed upper and lower mould, its structure comprises upper die and lower die, is upper cavity inside patrix, it is lower mode cavity inside counterdie, upper cavity and lower mode cavity close and form die cavity, and patrix establishes injection hole, and this injection hole is communicated with die cavity; The closing face place of patrix and counterdie establishes detent mechanism, and this detent mechanism comprises the positioning guide column be arranged on patrix, and is arranged on the detent on counterdie, positioning guide column and detent one_to_one corresponding; The cross section of positioning guide column is top is the trapezoidal of circular arc, detent establishes the inclined plane consistent with the trapezoidal hypotenuse angle of positioning guide column with the contact position of positioning guide column, the top diameter of positioning guide column is less than the top diameter of detent, and the base diameter of positioning guide column is greater than the base diameter of detent; The surrounding of die cavity is established sealing device and is communicated to the vacuum extractor of die cavity; Sealing device comprises the sealing gasket being arranged on patrix or counterdie closing face, and at least one sealing ring being arranged on counterdie or patrix closing face of corresponding sealing gasket, and the radius of sealing circle is less than the thickness of sealing gasket, and sealing ring was around die cavity one week.
Preferably, described sealing gasket is arranged on the closing face of patrix, the closing face being arranged on counterdie of the different sealing ring of six radiuses concentric successively.
Preferably, described sealing gasket is arranged on the closing face of counterdie, the closing face being arranged on patrix of the different sealing ring of six radiuses concentric successively.
Advantage of the present utility model: when upper and lower mould closes, the top arc of positioning guide column coordinates with the inclined plane of detent can make positioning guide column enter easily in detent, and be greater than the base diameter of detent due to the base diameter of positioning guide column, described closed after upper and lower mould closely can be locked, upper and lower mould closes that efficiency is high and precision is high; When the closing face of sealing gasket sealing upper and lower mould, be squeezed into the further reinforced seal effect of sealing gasket by sealing ring, guarantee to there is good sealing vacuumizing the closing face place at upper and lower mould.
Accompanying drawing explanation
Fig. 1 is the structural representation that high leakproofness is easy to a kind of embodiment of injection mold of closed upper and lower mould.
Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.
In figure 1 is patrix, 2 are counterdies, 3 are upper cavities, 4 are lower mode cavities, 5 are injection holes, 6 are positioning guide column, 7 are detents, 8 are sealing rings, 9 is sealing gaskets.
Detailed description of the invention
Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, 2, high leakproofness is easy to the injection mold of closed upper and lower mould, and its structure comprises patrix 1 and counterdie 2, being upper cavity 3 inside patrix 1, is lower mode cavity 4 inside counterdie 2, and upper cavity 3 forms die cavity with lower mode cavity 4 is closed, patrix 1 is established injection hole 5, this injection hole 5 is communicated with die cavity; Patrix 1 establishes detent mechanism with the closing face place of counterdie 2, and this detent mechanism comprises the positioning guide column 6 be arranged on patrix 1, and is arranged on the detent 7 on counterdie 2, positioning guide column 6 and detent 7 one_to_one corresponding; The cross section of positioning guide column 6 is top is the trapezoidal of circular arc, detent 7 establishes the inclined plane consistent with the trapezoidal hypotenuse angle of positioning guide column 6 with the contact position of positioning guide column 6, the top diameter of positioning guide column 6 is less than the top diameter of detent 7, and the base diameter of positioning guide column 6 is greater than the base diameter of detent 7; The surrounding of die cavity is established sealing device and is communicated to the vacuum extractor of die cavity; Sealing device comprises the sealing gasket 9 being arranged on patrix 1 or counterdie 2 closing face, and at least one sealing ring 8 being arranged on counterdie 2 or patrix 1 closing face of corresponding sealing gasket 9, the radius of sealing circle 8 is less than the thickness of sealing gasket 9, and sealing ring 8 was around die cavity one week.
Described sealing gasket 9 can be arranged on the closing face of patrix 1, the closing face being arranged on counterdie 2 of the different sealing ring 8 of six radiuses concentric successively.
