In view of the problems in actual production, the automatic retraction structure of the pin in the inner cavity of the die is designed, so that the labor intensity can be reduced, and the production efficiency can be improved.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model provides a pair of automatic structure that contracts in of mould inner chamber pin can realize contracting in the automation of two long round bosses to improve production efficiency, reduce intensity of labour.
In order to realize the purpose, the utility model discloses a technical scheme as follows: an automatic retraction structure of a pin in an inner cavity of a die comprises a platform, wherein two symmetrical semi-arc pins are arranged on the platform, the arc surfaces of the two semi-arc pins face outwards, long round bosses are arranged on the arc surfaces of the semi-arc pins, a conical gap is arranged between the two symmetrical semi-arc pins, and a liftable conical boss is arranged in the conical gap;
dovetail platforms are arranged on two sides of the conical boss, dovetail grooves are formed in the planes of the inner sides of the semi-arc pins, and the conical boss and the two symmetrical semi-arc pins are matched with the dovetail grooves through the dovetail platforms.
Preferably, the bottom of the semi-arc pin is provided with a positioning boss, and the positioning boss is arranged on the platform.
Preferably, the bottom of the conical boss is integrally provided with a connecting platform, and the connecting platform is connected with a lifting driving device.
The utility model discloses an useful part lies in:
1. the utility model discloses utilize the dovetail platform of toper boss both sides and the inboard dovetail cooperation of two symmetrical half arc pins, through the lift of toper boss, can realize that two symmetrical half arc pins shrink to the inboard to make the inner chamber passageway of product and the long round boss of half arc pin cambered surface noninterference.
2. The utility model discloses only need a lift drive to drive the toper boss and go up and down, alright in order to realize breaking away from of the long round boss of product and semi-arc pin cambered surface, realized the automation, reduced workman's intensity of labour, improved production efficiency.
Drawings
FIG. 1 is a schematic view of an automatic retracting structure of a pin in an inner cavity of a mold;
fig. 2 is a front view of a structure for automatically retracting a pin in an inner cavity of a mold.
In the figure: 1-conical boss, 2-semi-arc pin, 3-platform, 11-connecting platform, 12-dovetail platform, 21-positioning boss and 22-long round boss.
Detailed Description
To facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the automatic retraction structure for the pins of the inner cavity of the die comprises a platform 3, two symmetrical semi-arc-shaped pins 2 are arranged on the platform 3, the arc surfaces of the two semi-arc-shaped pins 2 face outwards, long round bosses 22 are arranged on the arc surfaces of the semi-arc-shaped pins 2, a tapered gap is arranged between the two symmetrical semi-arc-shaped pins 2, a liftable tapered boss 1 is arranged in the tapered gap, when the top of the tapered boss 1 is overlapped with the top of the semi-arc-shaped pins 2, the pin is a cylindrical inner cavity pin, two symmetrical long round bosses 22 are arranged on two sides of the cylindrical inner cavity pin, and an inner cavity channel with a long round hole on the side portion is poured.
The utility model discloses 1 both sides of toper boss are equipped with dovetail 12, and the inboard plane of 2 semi-arc pins is equipped with the dovetail, and the semi-arc pin 2 of toper boss 1 and two symmetries passes through dovetail 12 and dovetail cooperation, the utility model discloses utilize the dovetail 12 of 1 both sides of toper boss and the 2 inboard dovetail cooperations of two symmetrical semi-arc pins, through the lift of toper boss 1, can realize that two symmetrical semi-arc pins 2 shrink to the inboard to make the inner chamber passageway of product and the long boss 22 of 2 cambered surfaces of semi-arc pin noninterference.
The bottom of the semi-arc pin 2 is provided with a positioning boss 21, and the positioning boss 21 is arranged on the platform 3 to ensure that the bottom of the semi-arc pin 2 is fixed.
1 bottom an organic whole of toper boss is provided with connecting platform 11, and connecting platform 11 is connected with lift drive, the utility model discloses only need a lift drive to drive toper boss 1 and go up and down, alright break away from with long boss 22 of realizing product and 2 cambered surfaces of semi-arc pin, realized automaticly, reduced workman's intensity of labour, improved production efficiency.
