The specific implementation mode is as follows:
the utility model is further illustrated below with reference to specific embodiments and the accompanying drawings.
Referring to fig. 1 to 8, a product rapid demoulding structure is shown, which includes: the mold comprises an insert 1, a product 2 molded at one end of the insert 1, a thimble 3 which is telescopically mounted in the insert 1 and used for ejecting the product 2, and an air pipe 4 which is arranged at the other end of the insert 1 and used for blowing air to push the thimble 3 to move, wherein a gap 10 is formed between the insert 1 and the thimble 3, and when the thimble 3 ejects the product 2 upwards, air flow enters between the product 2 and the insert 1 through the gap 10 to generate air pressure, so that the product 2 is rapidly separated from the insert 1 through the generated air pressure. A movable ejector pin 3 is arranged in an insert 1, the ejector pin 3 is pushed to move by blowing through an air pipe 4, a product 2 on the insert 1 is ejected out, in the process of ejecting the product 2, air flow enters between the product 2 and the insert 1 from a gap 10, air pressure is generated between the product 2 and the insert 1, and then adsorption force between the product 2 and the insert 1 is lost, so that the product 2 is quickly detached from the insert 1.
The thimble 3 is provided with a limiting element 5 for limiting the moving stroke of the thimble 3 relative to the insert 1. The thimble 3 is limited by the limiting element 5, so that the thimble 3 is prevented from being completely pushed out of the insert 1 by airflow.
And a resetting element 6 for resetting the thimble 3 is installed at the other end of the insert 1. Through original paper 6 that resets can make thimble 3 accomplish product 2 and withdraw from back automatic re-setting to in quick continuous operation, also can make it receive gravity to fall back naturally through the weight that increases thimble 3 self certainly.
The limiting element 5 is a plug pin or a screw, the reset element 6 is a spring, the spring is sleeved on the thimble 3, and one end of the spring is pressed against the limiting element 5.
The other end of the insert 1 is formed with a first mounting hole 11 for mounting the reset element 6, and a first stroke groove 12 for moving the limiting element 5 is formed at an end of the first mounting hole 11.
A second mounting hole 13 for mounting the limiting element 5 is formed at one side of the first stroke groove 12, a sealing screw 14 is mounted on the second mounting hole 13, and a third mounting hole 31 for the limiting element 5 to pass through is formed on the thimble 3.
The gas pipe 4 is installed in a mold base plate 7, and a first sealing ring 71 and a second sealing ring 72 are disposed between the mold base plate 7 and the insert 1, wherein the first sealing ring 71 corresponds to the first installation hole 11, and the second sealing ring 72 corresponds to the first stroke groove 12.
The limiting element 5 can also be a convex ring, and the resetting element 6 can also be an elastic plastic part.
The lower end of the ejector pin 3 is pressed against the air pipe 4, and when the air flow blown by the air pipe 4 pushes away the ejector pin 3, the air flow can enter the gap 10.
The insert 1 is provided with a plurality of side by side inserts, and the trachea 4 is provided with a plurality of branch pipes to connect a plurality of insert 1.
In summary, in the work of the present invention, after the product 2 is injection molded or otherwise formed on the insert 1, the air tube 4 blows air into the insert 1 to push the ejector pin 3 upward, and further push the ejector pin 3 to eject the product 2 out of the insert 1, and after the ejector pin 3 moves, the air enters the cavity of the product 2 along the gap 10 between the ejector pin 3 and the insert 1, so that the negative pressure suction force between the product 2 and the insert 1 is lost and air pressure is generated to eject the product 2 out of the insert 1, thereby realizing the demolding of the product 2. Therefore, the ejector pin 3 and the air pressure are used together to eject the product 2, and the product 2 does not need to be manually taken down from the insert 1.
It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
