[0029] The present invention proposes a feeder for O-ring production, which includes a support member 100. A plurality of fixing members 200 for sleeving preformed parts are arranged at the bottom of the support member 100, and a blanking member 300 for ejecting the preformed parts on the fixing members 200 is also arranged at the bottom of the support member 100;

[0030] Wherein: The fixing member 200 includes a first insert 210 and a second insert 220 arranged oppositely, and the distance between the first insert 210 and the second insert 220 is adjustable; The fixing member 200 has a pushed-together state and a separated state. When the fixing member 200 is in the pushed-together state, the first insert 210 and the second insert 220 are close to and fit with each other; When the fixing member 200 is in the separated state, the first insert 210 and the second insert 220 are far away from each other;

[0031] When the fixing member 200 is in the pushed-together state, the distance between the first insert 210 and the second insert 220 is the smallest. The preformed part is sleeved outside the first insert 210 and the second insert 220, and then the distance between the first insert 210 and the second insert 220 is adjusted to expand and fix the preformed part. The preformed part is completely sleeved on the fixing member 200, which is convenient for fixing the preformed part.

[0032] To adapt to mold production, multiple fixing members 200 are arranged in a matrix distribution. Third inserts 230 are further provided on the fixing members 200 at the four corners of the matrix. The third inserts 230 are arranged on the side of the second insert 220 close to the first insert 210, and the height of the third insert 230 is greater than the height of the second insert 220. The arrangement of the third inserts 230 at the four corners of the feeder can act as foot pads when the feeder is positioned on the mold, playing a role in weight reduction and increasing the downward pressing stroke, so that there is a certain distance between the fixing member and the cavity, ensuring that the preform can fall into the corresponding cavity.

[0033] It should be noted that to ensure that the O-ring preform can be completely sleeved on the fixing member 200, the outer sides of the first insert 210 and the second insert 220 are set to be arc-shaped. When the first insert 210 and the second insert 220 are closed, they form a quasi-elliptical shape, which is convenient for the preform to be sleeved. And when the first insert 210 and the second insert 220 are separated, the outer diameter of the formed circle is 0.5 mm larger than that of the preform, so as to be able to completely expand the preform.

[0034] In this embodiment, the support member 100 includes a bottom plate 110 and a draw plate 120. The draw plate 120 is installed at the bottom end of the bottom plate 110. A plurality of first waist-shaped slots 123 are penetrated through the draw plate 120. A first positioning pin 113 that can slide along the connection line direction of the first insert 210 and the second insert 220 is slidably arranged in the first waist-shaped slots 123. The first positioning pin 113 is fixedly connected to the bottom plate 110; a push-pull type clamp 111 is fixed at the top end of the bottom plate 110, a connecting plate 122 is fixed at the top end of the draw plate 120, a first avoidance slot 112 is penetrated through the bottom plate 110, and the connecting plate 122 passes through the first avoidance slot 112 and is connected to the telescopic end of the push-pull type clamp 111 and the connecting plate 122 can slide in the first avoidance slot 112;

[0035] The first insert 210 of the fixing member 200 is fixed on the draw plate 120 by bolts and the first insert 210 can move with the movement of the draw plate 120. Here, a second avoidance slot 115 for avoiding the bolts on the first insert 210 is opened at the position corresponding to the first insert 210 on the bottom plate 110 to facilitate the movement of the draw plate 120; a through slot 121 is opened at the position of the draw plate 120 close to the first insert 210. The second insert 220 of the fixing member 200 passes through the through slot 121 and is fixed to the bottom plate 110 by bolts; the third insert also passes through the corresponding through slot and is connected to the bottom plate by bolts;

[0036] In this way, through the movement of the push-pull clamp 111, the push-pull clamp 111 can drive the extraction plate 120 to move through the connecting plate 122. The extraction plate 120 drives the first insert 210 to move closer to or away from the second insert 220 to perform the mold closing and mold opening of the fixing member 200. The setting of the first positioning pin 113 and the first waist-shaped groove 123 enables the extraction plate 120 to be pushed and pulled smoothly.

[0037] In this embodiment, the ejector member 300 includes a pressing plate 310. The pressing plate 310 is arranged below the extraction plate 120 and the pressing plate 310 can move in the vertical direction. A plurality of limiting grooves 320 are formed on the pressing plate 310 and a plurality of fixing members 200 respectively penetrate through the plurality of limiting grooves 320.

[0038] Specifically, a number of pull rods 330 are connected to the pressing plate 310. A number of second waist-shaped grooves 124 are formed through the extraction plate 120. A number of pull rods 330 respectively penetrate through the number of second waist-shaped grooves 124 and the pull rods 330 can slide in the second waist-shaped grooves 124 along the direction of the connection line between the first insert 210 and the second insert 220. The top ends of the pull rods 330 penetrate through the bottom plate 110 and the pull rods 330 are in sliding fit with the bottom plate 110. A limiting nut 340 is screwed on the top end of the pull rod 330 and a spring 350 is sleeved on the pull rod 330 at a position above the bottom plate 110 and both ends of the spring 350 are respectively pressed against the bottom plate 110 and the limiting nut 340. Handles 360 are arranged at both sides of the top end of the pressing plate 310 at positions of the extraction plate 120 and the bottom plate 110.

[0039] During feeding, only by pressing the handle 360, the pressing plate 310 moves downward to push out the preform on the fixing member 200. After the preform falls into the mold cavity, the handle 360 is released and the pressing plate 310 returns to its original position under the action of the spring 350.

[0040] To avoid affecting the movement of the extraction plate 120, a third avoidance groove 370 for avoiding the first positioning pin 113 is formed at a position on the pressing plate 310 corresponding to the first positioning pin 113.

[0041] To ensure the directional movement of the first insert 210, a slider 211 is arranged on one side of the first insert 210 away from the second insert 220. The limiting groove 320 is provided with a sliding groove 321 adapted to the slider 211 and the slider 211 slides in the sliding groove 321.

[0042] To facilitate the positioning of this feeder and the mold, a second positioning pin 114 is arranged at the bottom of the bottom plate 110 at a position on one side of the extraction plate 120 and the pressing plate 310. During feeding, inserting the second positioning pin 114 into the mold hole can realize the positioning of the feeder.

[0043] When the present invention is in use, first, the push-pull clamp 111 acts to drive the extraction plate 120 to move, thereby driving a plurality of first inserts 210 to approach the second insert 220 respectively to perform the mold closing of the fixing member 200. Then, the preform is sleeved outside the first insert 210 and the second insert 220. Then, the push-pull clamp 111 acts to drive the extraction plate 120 to move in the reverse direction, so that the first insert 210 moves away from the second insert 220, and the first insert 210 and the second insert 220 expand the preform to complete the fixation of the preform. Then, the second positioning pin 114 is inserted into the corresponding mold hole positions, so that a plurality of fixing members 200 respectively correspond to a plurality of cavities of the mold one by one. The handle 360 is pressed downward to drive the pressing plate 310 to move downward. When the pressing plate 310 moves downward, the preform on the fixing member 200 is pushed out, and the preform falls into the cavity. Then, the handle 360 is released, and the pressing plate 310 returns to its original position under the action of the spring 350. The feeder can be taken away.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
