As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1 to 3, the present embodiment discloses a swing type slider core pulling device u (a), which includes a swing arm movement mechanism 100, a side ejecting block 200 and a limit clutch mechanism 300, and realizes a long-stroke reverse-buckling glue position in a limited mold space, thereby solving the problem of injection molding production.
the swing arm movement mechanism 100 includes a slide insert 110, a swing arm 120, and a hydraulic cylinder 130, and provides a core-pulling power for the slide insert 110 in a swing manner. Referring to fig. 6-7, the slide insert 110 is slidably inserted into and removed from the cavity for forming the undercut 410 of the product u (b). In one practical production example, the stroke length of the slide insert 110 may reach 250mm to form the undercut hole 410 with a corresponding depth. When the slide insert 110 is used for core pulling, the slide insert sequentially passes through a first core pulling stroke and a second core pulling stroke. Illustratively, the swing arm motion mechanism 100 further includes a holder 140, and the slide insert 110 is slidably held on the holder 140 and out of the cavity.
The sliding power of the slide insert 110 comes from the swing arm 120. Specifically, one end of the swing arm 120 is hinged to the mold plate u (c), and the other end is connected to the slide insert 110 to drive the slide insert 110 to slide. The output end of the hydraulic cylinder 130 is connected to the middle section of the swing arm 120, and is used for driving the swing arm 120 to swing around the hinge shaft of the swing arm 120 and the template u (c).
Illustratively, the fixed end of the hydraulic cylinder 130 is mounted to the die plate u (c). The linear motion output from the hydraulic cylinder 130 is transmitted to the slide insert 110 by the swing of the swing arm 120, and belongs to an indirect drive system. Illustratively, the swing arm 120 is connected to the template u (c) through a connecting arm 150, that is, one end of the swing arm is hinged to the connecting arm 150, and the connecting arm 150 is mounted on the template u (c).
Compared to the driving method in which the hydraulic cylinder 130 directly drives the slide insert 110, the hydraulic cylinder 130 in the indirect driving method requires an effective operation stroke for compression. For example, in the aforementioned 250mm stroke length application, the actuation stroke of the hydraulic cylinder in the direct drive mode needs to be at least 260mm, which exceeds the stroke range of the standard hydraulic cylinder series, and the hydraulic cylinder 130 needs to be customized and the size of the mold needs to be increased, which is easy to cause the motion interference between the mold and the injection molding machine component; on the contrary, the actuation stroke of the hydraulic cylinder in the indirect driving mode only needs 160mm, and the hydraulic cylinder 130 can be directly selected and applied to the existing mold, so that the application difficulty and the cost are reduced.
Compared with the traditional inclined guide post driving core-pulling mode, the hydraulic cylinder 130 indirect driving mode can realize large-stroke core-pulling. Supplementary explanation, utility model people discover, need utilize the mould die sinking motion as the power supply by oblique guide pillar driven mode of loosing core, but the stroke of loosing core of adaptation is very little and easily send out the motion card and die, does not possess the ability of loosing core of large stroke.
Illustratively, the swing arm 120 is connected to the slide insert 110 by a slide bar 160 and a slide sleeve 170. The sliding sleeve 170 is sleeved at the end of the sliding rod 160, the sliding sleeve 170 and the sliding block insert 110 rotate relatively, the freedom of movement between the swing arm 120 and the sliding block insert 110 is increased, and the relative position is adaptively adjusted in the driving process, so that the locking is prevented.
the side top block 200 presses against the outer surface of the product u (b) and is engaged/disengaged with/from the slide insert 110 by the spacing clutch mechanism 300. When the sliding block insert 110 slides in the first core-pulling stroke, the sliding block insert 110 is kept separated from the side ejector block 200, and the side ejector block 200 reliably pushes against the product U (b), so that the sliding block insert 110 is smoothly separated from the product U (b), the sliding block insert 110 is prevented from being adhered to the product U (b) in the long-stroke sliding process, and the surface quality of the product U (b) after core pulling is ensured; when the slide insert 110 slides in the second core-pulling stroke, the slide insert 110 and the side top block 200 are engaged and move synchronously, and the two are separated from the product u (b) together to realize complete core-pulling.
It is understood that the clutching action between the side top block 200 and the slide insert 110 is achieved by the limit clutching mechanism 300. Meanwhile, the limiting clutch mechanism 300 also has a limiting function on the side top block 200 during mold closing, so that the side top block 200 is reliably pressed in the cavity to form the corresponding outer surface of the product U (b), and the position change is prevented.
Exemplary, the limiting clutch mechanism 300 includes a clutch assembly 310 and a limiting assembly 320. The clutch assembly 310 is used to effect engagement/disengagement between the slide insert 110 and the side knock-out block 200, and the stop assembly 320 is used to lock the side knock-out block 200 at the beginning of the first core back stroke and to release the side knock-out block 200 before the end of the first core back stroke. Illustratively, the motion releasing action of the stop assembly 320 on the side top block 200 occurs prior to the engaging action of the slide insert 110 and the side top block 200, and the motion locking action of the stop assembly 320 on the side top block 200 occurs after the separating action of the slide insert 110 and the side top block 200, so as to prevent motion accidents.
Exemplarily, the limiting assembly 320 is driven by the slide insert 110 to perform locking and releasing actions, so that synchronization of movement is ensured and motion accidents are prevented, and a driving source is not required to be additionally arranged, so that a driving structure is simplified, and further, space is saved and the volume of the mold is reduced.
Referring to fig. 1-5, the limiting assembly 320 includes a guiding element 321 and a limiting element 322. Wherein, the guiding element 321 is fixedly connected to the slide insert 110 and moves synchronously with the latter; the stopper 322 moves on the guide 321 to protrude in front of the core pulling direction of the side knock out block 200 or to be withdrawn from the front of the core pulling direction. When the stopper 322 is extended, the movement of the side top block 200 is locked to keep pressing against the outer surface of the product u (b); when the retainer 322 is withdrawn, the side top block 200 is released and can be detached from the product u (b). Wherein, the stopper 322 is guided by the movement of the guiding member 321 and keeps connected with the stencil u (c).
exemplarily, the guide member 321 has a guide groove 321a on a surface thereof, and the stopper 322 has a sliding portion 322 c. The sliding portion 322c is slidably held in the guide groove 321a in the extending direction of the guide groove 321a, and is guided by precise movement. The guide groove 321a includes a first groove segment 321a1 and a second groove segment 321a2, which are not parallel to each other. The first groove section 321a1 extends along the core pulling direction of the side ejector block 200 to adapt to a first core pulling stroke; the second slot segment 321a2 extends from the end of the first slot segment 321a1 in a direction away from the side top block 200 to accommodate the second core back stroke. Illustratively, the first slot segment 321a1 has an obtuse included angle with the second slot segment 321a 2.
In the core pulling process, the sliding portion 322c slides through the first slot segment 321a1 and the second slot segment 321a2 in sequence. In the first groove section 321a1, the sliding direction of the stopper 322 relative to the guide member 321 is parallel to the slide block insert 110, and the side top block 200 is kept locked; at second slot segment 321a2, stop 322 releases side top piece 200.
Illustratively, the second slot segment 321a2 is located on the side of the first slot segment 321a1 proximate to product u (b). Illustratively, a third slot segment 321a3 is connected to an end of the second slot segment 321a2 distal from the first slot segment 321a 1. Meanwhile, the first slot segment 321a1 and the third slot segment 321a3 are separated on both sides of the track of the second slot segment 321a 2. When the sliding part 322c slides from the second groove section 321a2 into the third groove section 321a3, the stopper 322 keeps away from the side top block 200, and the core-pulling movement of the side top block 200 is not limited.
Exemplarily, the third slot segment 321a3 has a trumpet-shaped structure, and an end thereof away from the second slot segment 321a2 is opened to an end surface of the guide member 321. Wherein the big end of the trumpet-shaped structure is located on the end surface of the guide member 321, and the small end is located at the connection position of the second slot segment 321a2 and the third slot segment 321a 3. The stopper 322 is thus removable from the guide 321 for replacement and maintenance.
illustratively, the stopper 322 includes a free seat 322a and a stop 322 b. The sliding portion 322c is disposed on a side wall of the movable seat 322a, and the stopper 322b slidably extends outside the movable seat 322a to be stopped in front of the core pulling direction of the side ejector 200. In other words, the stopper 322b and the movable seat 322a slide relative to each other, and the sliding direction of the stopper 322b and the core pulling direction of the side knock out block 200 are not parallel to each other.
Illustratively, the traveling block 322a has a slide groove, and the stopper 322b is slidably held in and out of the slide groove. When the block 322b is slidingly protruded out of the chute, the block 322b is blocked in front of the side top block 200; when the stopper 322b is slidingly received in the slide groove, the movement of the side knock out block 200 in the core pulling direction is released.
The stopper 322b is connected to the movable seat 322a by a return spring 322 d. The direction of the elastic force of the return spring 322d is defined such that the stopper 322b is positioned in front of the core-pulling direction of the side knock-out block 200. When the stopper 322b is slidably received in the chute, the return spring 322d accumulates elastic potential energy. When the external force acting on the stopper 322b disappears, the return spring 322d releases the elastic potential energy to drive the stopper 322b to return, so that the stopper 322b protrudes out of the chute again. In addition, the return spring 322d also has the functions of preventing impact, absorbing energy and buffering. The return spring 322d can be of a wide variety of types including compression, extension, torsion, and the like.
Illustratively, the protruding end of the stopper 322b has an inclined acting surface, and the inclined acting surface forms an acute angle with the sliding direction of the stopper 322 b. The inclined active surface is typically held opposite to the slide insert 110, and functions at least to prevent the stopper 322b from rigidly colliding and impacting with the slide insert 110 during mold clamping, to protect the side top block 200, and to ensure positional accuracy.
Exemplarily, both ends of the sliding part 322c have inclined fitting surfaces matching the included angle between the first slot segment 321a1 and the second slot segment 321a2, so that the sliding part 322c slides smoothly from the first slot segment 321a1 into the second slot segment 321a 2.
Exemplarily, the clutch assembly 310 includes a clutch groove portion 311 and a clutch end portion 312, the clutch groove portion 311 has a first clutch wall 311a and a second clutch wall 311b which are opposite to each other, the clutch end portion 312 is held between the first clutch wall 311a and the second clutch wall 311b and is reciprocally and slidably engaged with the first clutch wall 311a or the second clutch wall 311b, one of the clutch groove portion 311 and the clutch end portion 312 is located on the slide insert 110, and the other one is located on the side top block 200. For example, when the clutch end 312 engages the first clutch wall 311a, the side top block 200 remains engaged with the slide insert 110 for synchronous movement; there is relative movement between the side top block 200 and the slide insert 110 when the clutch end 312 is not engaged with the first clutch wall 311 a.
Exemplarily, the sliding directions of the slide insert 110 and the side top block 200 and the clutch end 312 are parallel, so that the synchronous and smooth motion is ensured.
