The outer end of the inclined top 53 is provided with an elastic piece 54, the outer end of the elastic piece 54 is propped against the inclined top 53, and the inner end is propped against the sliding block 51. If the slide 51 moves toward the inside of the mold, the elastic member 54 is correspondingly compressed, and when the compressed elastic member 54 is restored, a force is applied to move the inclined top 53 toward the outside, where the movement of the inclined top 53 is performed along the extending direction of the chute 512.
When the mold is opened, the fixed mold 40 drives the inclined guide pillar 52 to move upwards, and then drives the sliding block 51 to slide outwards, at this time, the inner end of the inclined top 53 is reversely buckled by a product and cannot move outwards along with the sliding block 51, the inclined top 53 can move inwards (obliquely upwards) along the direction of the chute 512 and gradually separate from the clamping surface 12 of the clamping hook 11 of the wheel rim 10, meanwhile, the elastic piece 54 is driven to be compressed, when the inclined top 53 is completely separated from the clamping surface 12 of the clamping hook 11, the inclined top 53 does not move inwards of the mold any more, and moves outwards along with the sliding block 51 until the sliding block 51 slides outwards in place, at this time, the inclined top 53 can not block the clamping hook 11 any more, and the wheel rim 10 is ejected under the action of the ejection mechanism on the movable mold 30 to finish product demolding.
As shown in fig. 3 to 5, the outer end of the inclined top 53 is connected with a limiting member 55 coaxial with the inclined top, a limiting ring 551 is arranged at the outer end of the limiting member 55, a limiting step 513 is arranged on the inner wall of the chute 512, the outer end of the elastic member 54 abuts against the limiting ring 551, and the inner end abuts against the limiting step 513. That is, the inclined top 53 is provided with the elastic member 54 by a limiting member 55, and the elastic member 54 is disposed between the limiting ring 551 of the limiting member 55 and the limiting step 513 of the slider 51, so that when the inclined top 53 moves toward the inner side of the mold, the limiting member 55 moves along with the inclined top 53, and the elastic member 54 is compressed between the limiting ring 551 and the limiting step 513. In addition, during die assembly, the inclined top 53 is reset under the restoring force of the elastic member 54 until the outer end of the inclined top 53 abuts against the limiting step 513, that is, the inclined top 53 is reset in place, at this time, the inner end face of the inclined top 53 is flush with the inner end face of the slide block 51, and the elastic member 54 is still in a compressed state. A stop step 513 in the chute 512 divides the chute 512 into an inner section and an outer section, the roof 53 moving in the inner section and the stop 55 moving in the outer section of the chute 512.
In this embodiment, the elastic member 54 is a spring, and the spring is sleeved on the outer periphery of the limiting member 55. In this way, the spring is less likely to deflect from the axis when compressed.
In this embodiment, the limiting member 55 is a bolt, and a connection hole 531 in threaded engagement with the bolt is provided at the outer end of the inclined top 53. The head of the bolt forms the limit ring 551, and the rod part of the limit ring is in threaded fit with the connecting hole 531 of the inclined top 53. The length design of connecting hole 531 is longer, so the connecting length of locating part 55 and connecting hole 531 can be adjusted according to actual demand, and the connecting length of locating part 55 and connecting hole 531 is long, and then the distance between corresponding locating part 55 outside end stop collar 551 and the spacing step 513 shortens, and then when the compound die, the same spring is longer by the length of compression, and its restoring force is bigger.
The outer end of the slide block 51 is provided with an inclined surface 514, the inclined surface 514 is inclined towards the inner side of the mold in the direction of the fixed mold 40, and the fixed mold 40 is provided with a pressing surface 41 corresponding to the inclined surface 514. When the mold is closed, the pressing surface 41 cooperates with the inclined surface 514 to press the slide block 51 inwards, and when the mold is closed in place, the slide block 51 is reset to the position, and the pressing surface 41 correspondingly abuts against the inclined surface 514. While the pressing surface 41 and the inclined surface 514 cooperate with the auxiliary slide block 51 to slide and reset toward the inner side of the mold.
Preferably, an L-shaped step 515 is provided at the outer side of the slider 51, the vertical surface of the step is the inclined surface 514, and the inclined hole 511 is provided on the horizontal surface of the step. If the structure design on the sliding block 51 is more compact, the volume is smaller.
Convex edge portions 516 are arranged on two sides of the sliding block 51 in an extending mode, and sliding grooves corresponding to the convex edge portions 516 are formed in the movable die 30. When the slider 51 slides, the flange 516 moves in the chute. The design of the convex edge 516 and the chute has guiding and limiting functions on the sliding of the sliding block 51, so that the sliding block 51 moves more stably.
The outer end of the movable mold 30 corresponding to the sliding block 51 is provided with a limiting block 31. The limiting block 31 is correspondingly positioned at the outer side of the sliding block 51, and when the sliding block 51 slides towards the outer side of the die, the limiting hole can prevent the sliding block 51 from sliding out of the movable die 30. In this embodiment, the hooks 11 on the rim 10 are uniformly arranged along the circumferential direction of the rim 10, and the demolding mechanisms 50 are correspondingly arranged in one-to-one correspondence with the hooks 11, so that the demolding mechanisms 50 are correspondingly uniformly arranged along a circumferential direction (concentric with the rim 10). The mold is square, and the dimension of the mold is longer along the sliding direction of the sliding block 51 (such as the corner of the mold), the mold is provided with a mounting groove 32 corresponding to the sliding block 51, the outer side end of the mounting groove 32 is closed, and the sliding block 51 reciprocates in the mounting groove 32. The outer end of the mounting groove 32 is not closed to form a through groove corresponding to the short dimension along the sliding direction of the slide block 51, and the stopper 31 is provided on the side surface of the movable die 30 corresponding to the through groove mounting groove 32.
The working process of the die is as follows: when the mold is opened, the fixed mold 40 drives the inclined guide pillar 52 to move upwards, and then drives the sliding block 51 to slide towards the outer side of the mold, under the action of the clamping surface 12 of the clamping hook 11, the inclined top 53 moves towards the inner side of the mold (moves upwards obliquely) along the direction of the chute 512 and gradually breaks away from the clamping surface 12 of the clamping hook 11 of the rim 10, meanwhile drives the elastic piece 54 to be compressed, when the inclined top 53 is completely separated from the clamping surface 12 of the clamping hook 11, the inclined top 53 does not move towards the inner side of the mold any more, and moves towards the outer side of the mold along with the sliding block 51 until the sliding block 51 slides towards the outer side to be in place, at the moment, the inclined top 53 can not block the clamping hook 11 any more, and also resets under the action of the resetting piece, and finally the rim 10 is ejected out under the action of the ejection mechanism on the movable mold 30 to finish product demolding. During die assembly, the fixed die 40 moves downwards, the slide block 51 slides towards the inner side of the die under the cooperation of the inclined guide post 52, the inclined hole 511, the inclined surface 514 and the pressing surface 41, and the pressing surface 41 presses the inclined surface 514 to press the slide block 51 towards the inner side of the die when die assembly is in place.
