Abstract
The utility model relates to the field of mold devices, in particular to a round mold core of an injection mold with an exhaust groove; the glue injection mold comprises a circular mold core, wherein a first glue position section, a second glue position section, an inclined plane glue position section, a third glue position section and a glue sealing surface section are sequentially arranged on the circular mold core from top to bottom; an inclined annular exhaust groove is formed in the periphery of the round mold core below the glue sealing surface section; the radius of the glue sealing surface section is smaller than that of a circular hole section matched with the glue sealing surface section on the main mold core, and a gap between the glue sealing surface section and the circular hole section is a shallow exhaust gap; the round mold core of the injection mold with the exhaust grooves can exhaust quickly and can also seal plastic cement without fluffy burrs.
Description
Technical Field
The utility model relates to a mold device field especially relates to injection mold circle mold core with air discharge duct.
Background
The plastic mold is a mold and a tool for injection molding of plastic products in industrial production; at present, when products are produced, because some plastic products are easy to generate gas in the injection molding process, the gas is not easy to be discharged and easy to generate residues, and the plastic is easy to fluff and stab.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an ability fast exhaust also can seal the plastic and not have the injection mold round mold core with air discharge duct of burr.
The technical scheme of the utility model as follows:
the injection mould round mould core is provided with an exhaust groove; the glue injection mold is characterized by comprising a circular mold core, wherein the circular mold core is sequentially provided with a first glue position section, a second glue position section, an inclined plane glue position section, a third glue position section and a glue sealing surface section from top to bottom; an inclined annular exhaust groove is formed in the periphery of the round mold core below the glue sealing surface section; the radius of the glue sealing surface section is smaller than that of a circular hole section matched with the glue sealing surface section on the main mold core, and a gap between the two is a shallow exhaust gap.
And a vertical exhaust groove is formed in the round mold core below the annular exhaust groove. Therefore, the exhaust groove can be continuous with the annular exhaust groove, so that the rapid gas flow is facilitated, and the exhaust speed is accelerated.
The top surface of the vertical exhaust groove extends to the bottom surface of the annular exhaust groove. Because the top surface of the exhaust groove extends to the bottom surface of the annular groove, the gas can quickly enter the annular groove, and the exhaust speed is accelerated.
The vertical exhaust groove and the horizontal plane form an included angle of 45 degrees. Is convenient for quickly cleaning impurities generated by plastics.
The width of the glue sealing surface section is kept to be 1 mm. And a certain shallow exhaust gap (the gap needs to be smaller than the overflow edge value of the plastic) is kept between the round die core and the round die core, so that the plastic can be rapidly exhausted and can be sealed without fluffing and thorns.
And the contact surface of the glue sealing surface section, which is contacted with the core hole of the main die, is a conical transition surface. The conical transition surface is adopted, so that the mold core can be conveniently sealed and the fit clearance can be conveniently adjusted.
The utility model has the advantages that: the annular exhaust groove is arranged to facilitate exhaust; because the glue sealing surface section and the round die core are directly provided with annular groove transitions, a gap is reserved for air conveniently, and air is exhausted conveniently; because set up vertical exhaust groove on the round mold core of annular exhaust groove below, make the exhaust groove can be continuous with annular exhaust groove like this, do benefit to the gas fast flow for exhaust speed.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic perspective view of the present invention;
in the attached drawing, 1 is the circle mold core, 2 is the first position section of gluing, 3 is the second position section of gluing, 4 is the third position section of gluing, 5 is gluing the glue face section, 6 is annular air discharge duct, 7 is vertical air discharge duct, 8 inclined planes glue the position section, 9 main mold cores.
Detailed Description
Referring to fig. 1, the circular mold core of the injection mold with the exhaust groove comprises a circular mold core, and a first glue position section 2, a second glue position section 3, an inclined glue position section 8, a third glue position section 4 and a glue sealing surface section 5 are sequentially arranged on the circular mold core from top to bottom; the glue position surface section and the round mold core are transited through an annular groove, and an inclined annular exhaust groove is formed in the periphery of the round mold core below the glue position surface section; the radius of the glue sealing surface section is smaller than that of a circular hole section matched with the glue sealing surface section on the main mold core, and a gap between the two is a shallow exhaust gap. (the clearance is required to be smaller than the overflow edge value of the plastic) the annular exhaust groove 6 is arranged to facilitate exhaust; because the glue sealing surface section and the round die core are directly provided with annular groove transitions, a gap is reserved for air conveniently, and air is exhausted conveniently; because set up vertical exhaust groove on the round mold core of annular exhaust groove below, make the exhaust groove can be continuous with annular exhaust groove like this, do benefit to the gas fast flow for exhaust speed.
And a vertical exhaust groove 7 is formed in the round mold core below the annular exhaust groove. Therefore, the exhaust groove can be continuous with the annular exhaust groove, so that the rapid gas flow is facilitated, and the exhaust speed is accelerated.
The top surface of the vertical exhaust groove extends to the bottom surface of the annular exhaust groove. Because the top surface of the exhaust groove extends to the bottom surface of the annular groove, the gas can quickly enter the annular groove, and the exhaust speed is accelerated.
The included angle between the vertical exhaust groove and the horizontal plane is 45 degrees (the vertical exhaust groove adopts an inclined plane with an inclination angle of 45 degrees). Is convenient for quickly cleaning impurities generated by plastics.
The width of the glue sealing surface section is kept to be 1mm, and the depth of the annular exhaust groove is 0.3 mm. And a certain shallow exhaust gap (the gap needs to be smaller than the overflow edge value of the plastic) is kept between the round die core and the round die core, so that the plastic can be rapidly exhausted and can be sealed without fluffing and thorns.
And the contact surface of the glue sealing surface section, which is in contact with the inner hole of the main die core 9, is a conical transition surface. The conical transition surface is adopted, so that the mold core can be conveniently sealed and the fit clearance can be conveniently adjusted.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
