The utility model discloses an advantage: last lower mould closure is efficient and the precision is high, avoid in the die cavity forming high temperature high -pressure gas and cause the damage to the product, effectively improved the yield of product.
Description
Technical field
The utility model relates to a kind of injection mold, be specifically related to a kind ofly be vented and be easy to the injection mold of closed upper and lower mould.
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.
Existing injection mold also often there will be mould filling deficiency in injection moulding process; the air retained is compressed the compressed air of rear formation high temperature; and exist and to burn the problem such as goods and product surface streamline, focal spot, the main cause of these problems be die cavity exhaust bad caused by.
Utility model content
The utility model proposes and can be vented and be easy to the injection mold of closed upper and lower mould, its object is intended to overcome prior art above shortcomings, realizes the accurately closed of upper and lower mould and discharges die cavity compressed air in time.
Technical solution of the present utility model: can be vented and be 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 counterdie, and is arranged on the detent on patrix, 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; Patrix is also provided with the steam vent being communicated with die cavity top, and establish check valve in this steam vent, check valve place air outwardly circulates by die cavity.
Preferably, described steam vent is arranged on patrix and air inlet is positioned at the top of die cavity, and gas outlet is positioned at the side of patrix, and check valve is arranged on air inlet place.
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 injection mo(u)lding, can be discharged outside mould by check valve after the air in die cavity is compressed, thus avoid in die cavity, forming high temperature and high pressure gas and causing damage to product, effectively improve the yield rate of product.

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, 3, can be vented and be easy to the injection mold of closed upper and lower mould, 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 counterdie 2, and is arranged on the detent 7 on patrix 1, 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; Patrix 1 is also provided with the steam vent 8 being communicated with die cavity top, and establish check valve 9 in this steam vent 8, check valve 9 place air outwardly circulates by die cavity.
Described steam vent 8 is arranged on patrix 1 and air inlet is positioned at the top of die cavity, and gas outlet is positioned at the side of patrix 1, and check valve 9 is arranged on air inlet place.
According to above structure, what the utility model provided be vented and be easy to the injection mold of closed upper and lower mould, when patrix 1 closes with counterdie 2, the top arc of positioning guide column 6 coordinates with the inclined plane of detent 7 can make positioning guide column 6 enter in detent 7 easily, and be greater than the base diameter of detent 7 due to the base diameter of positioning guide column 6, patrix 1 and counterdie 2 closely can be locked after closed; In addition, when closed, even if having minor deviations between patrix 1 and counterdie 2, also can be corrected with the coordinating of detent 7 with inclined plane by positioning guide column 6, the high efficiency precision positioning finally realizing upper and lower mould, with closed, when injection mo(u)lding, can be discharged outside mould by check valve 9 after the air in die cavity is compressed, thus avoid in die cavity, forming high temperature and high pressure gas and causing damage to product, effectively improve the yield rate of product.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
