So that the guide rod 405 of the guiding mechanism 402 can only push one four-hole pipe clamp 10 sideways at a time, while the remaining four-hole pipe clamps 10 remain confined inside the pipe clamp sleeve 404.

A rack support 210 is arranged at the bottom of the lower die 2, and two racks 211 which are opposite to each other in front and back and are parallel to the die moving guide rail 3 are horizontally arranged on the rack support 210;
the trigger power assembly comprises two racks 211, a first incomplete gear 408 which is meshed with the two racks 211 in the reciprocating process respectively, a second incomplete gear 410 is coaxially mounted on a first rotating shaft 409 of the first incomplete gear 408, a complete gear 411 is mounted on one side of the second incomplete gear 410 in a meshed mode, a wire collecting roller 413 is coaxially mounted on a second wheel shaft 412 of the complete gear 411, a guide groove rail 414 which is parallel to the running direction of the lower die 2 is arranged on one side of the wire collecting roller 413, a sliding push block 415 is mounted on the guide groove rail 414 in a sliding mode, a guide rod 405 is mounted on the outer end face of the sliding push block 415, the inner end face of the sliding push block 415 is connected with the end wall of the guide groove rail 414 through a compression spring 416, and the sliding push block 415 and the wire collecting roller 413 are connected through a pull rope 417.
The first axle 409 and the second axle 412 are both fixedly mounted on one side of the loading station through axle seats (not shown).
The working principle of the device is as follows:
the method comprises the following steps of firstly, manually stacking four-hole pipe clamps:
when the four-hole pipe clamp 10 is manually opened, the fixed clamp arm 101 and the opening and closing clamp arm 102 are clamped at two sides of the pipe clamp guide core 407 and are made to fall along the inner side wall of the pipe clamp sleeve 404, the shapes of the pipe clamp guide core 407 and the rubber coating 20 are matched, and the shapes of the inner side wall of the pipe clamp sleeve 404 and the outer side wall of the four-hole pipe clamp 10 are matched. The four-bore clamp 10 is neatly stacked inside the clamp sleeve 404;
under the influence of gravity, the lowermost four-hole pipe clamp 10 will contact the surface of the adaptor platform 403, since the height between the lower end of the clamp sleeve 404 and the upper surface of the adaptor platform 403 is greater than the height of one four-hole pipe clamp 10, but less than the height of two of said four-hole pipe clamps 10. Therefore, only one four-hole pipe clamp 10 is completely exposed below the pipe clamp sleeve 404 to serve as the four-hole pipe clamp 10 to be loaded;
secondly, feeding:
after the injection molding of the four-hole pipe clamp 10 of the previous wheel in the lower die 2 is completed and the material is discharged, the second jacking cylinder 208 of the jacking assembly contracts downwards, so that the conical extrusion block 207 is withdrawn from the lower die 2, and thus the conical extrusion block 207 cannot form an obstacle to the horizontal movement of the lower die 2.
The first jacking cylinder 205 contracts downwards to enable the rubber coating mold 203 to descend (in a film closing state), so that when the subsequent four-hole pipe clamp 10 is pushed into the pipe clamp limiting cavity 201, the interference of the rubber coating mold 203 protruding in the middle is avoided, and the feeding progress can be accelerated;
then, the lower die 2 is driven to move along the die moving guide 3 from the injection molding station to the transfer platform 403 of the feeding station, just before the lower die 2 is abutted to the transfer platform 403, a rack 211 below the lower die 2 is engaged with the first incomplete gear 408, as the lower die 2 moves forward, the rack 211 pushes the first incomplete gear 408 to rotate in situ, the rotating first incomplete gear 408 drives the second incomplete gear 410 coaxially mounted with the rotating second incomplete gear 410 to rotate, the rotating second incomplete gear 410 drives the complete gear 411 engaged with the rotating second incomplete gear to rotate, so that the wire take-up roller 413 coaxially mounted with the complete gear 411 rotates, the pull rope 417 is gradually wound on the wire take-up roller 413, the sliding push block 415 connected to one end of the pull rope 417 and the guide rod 405 thereon move to the side away from the pipe clamp sleeve 404, and the compression spring 416 is pressed.
When the lower die 2 is butted with the switching platform 403, the rack 211 meshed and contacted with the first incomplete gear 408 is moved to the end, the meshed state is cancelled, at this time, the second incomplete gear 410 which is just coaxially arranged with the first incomplete gear 408 is just rotated to the state of no longer meshed with the complete gear 411, the take-up roller 413 coaxially arranged with the complete gear 410 is not restrained any more, under the action of the elastic force of the compression spring 416, the sliding push block 415 with the guide rod 405 thereon moves to a side close to the pipe clamp sleeve 404 and pushes the four-hole pipe clamp 10 opposite to the guide rod 405 to the inside of the pipe clamp limiting cavity 201 along the adapting platform 403 and the guide groove 5 on the surface of the lower die 2, in order to make the four-hole pipe clamp 10 accurately fall into the inside of the pipe clamp limiting cavity 201, and a blocking wall 6 matched with the outer side clamping wall of the four-hole pipe clamp 10 is arranged above the lower die 2 of the feeding station. After the pushed four-hole pipe clamp 10 contacts the retaining wall 6 in the pushing process, the pushed four-hole pipe clamp slides into the pipe clamp limiting cavity 201 under the action of gravity;
then, the lower die 2 is driven to reset from the feeding station to the injection station, at the moment that the lower die 2 leaves from the station butted with the transfer platform 403, the first incomplete gear 408 continues to rotate due to the previous rotation inertia and rotates to be meshed with the other rack 211, but at the moment, the second incomplete gear 410 coaxially mounted with the first incomplete gear 408 does not mesh with the complete gear 411 when rotating, so that the wire receiving roller 413 cannot be driven to receive wires again, and the material guiding step only occurs once in the process that the lower die 2 is butted with the transfer platform 403;
thirdly, injection molding:
when the lower die 2 moves to an injection station, the first jacking cylinder 205 is started to ascend, so that the two rubber coating dies 203 in a die closing state and the guide slide 204 are jacked upwards, the fixed clamping arms 101 and the opening and closing clamping arms 102 of the four-hole pipe clamp 10 are respectively positioned at two sides of the rubber coating dies 203 in the die closing state, the primary positioning of the four-hole pipe clamp 10 is completed, then the second jacking cylinder 208 is started to ascend, the conical extrusion block 207 ascends to the bottoms of the two rubber coating dies 203 with wedge-shaped structures through the abdicating holes 209 and extrudes the two rubber coating dies 203 to move towards two sides along the guide slide 204, the contact parts of the four-hole pipe clamp 10 and the rubber coating dies 203 are extruded, the fixed clamping arms 101 and the opening and closing clamping arms 102 are extruded to the side walls of the pipe clamp limiting cavities 201, and the accurate positioning of the fixed clamping arms 101 and the opening and closing clamping arms 102 of the four-hole pipe clamp 10 on the side walls of the pipe clamp limiting cavities 201 is realized, an injection molding cavity for encapsulation with a stable cavity is also formed between the encapsulation mold 203 and the four-orifice pipe clamp 10. And then the upper die 1 is pressed down to finish the process of injection molding and encapsulation.
The device can realize automatic feeding of the four-hole pipe clamp 10, and accurate positioning of the four-hole pipe clamp 10 on the top of a mold after feeding is realized, so that the injection molding efficiency of the four-hole pipe clamp is improved.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
