Description

Technical field

[0001] The utility model relates to the technical field of injection molds, in particular to a long core-pulling slider mechanism for a Y-shaped product. [Background Technology]

[0002] The long core-pulling slider mechanism of the Y-shaped product in the existing technology generally adopts an oil cylinder in each direction of the two sliders to control the order of the oil cylinders' movement to realize the core-pulling action. This method requires strict control of the mold cylinder's forward and backward movement. On the one hand, the order of the mold core-pulling action must be specially noted. If the action is slightly unsmooth or stuck, it will cause the mold to be pressed.

[0003] Secondly, installing two sets of oil cylinder slide blocks in the mold requires a larger space, which requires the mold to be larger, and the mold cost increases accordingly. The tonnage of the injection molding machine also needs to be increased accordingly. The advance and retreat of the two sets of core pulling actions causes the injection molding cycle to be lengthened accordingly.

[0004] For this purpose, a beer core is inserted into the mold, and a fixture is used outside the mold to pull the core of the product. This method has a long injection molding cycle, low production efficiency, and unstable production quality. [Utility Model Content]

[0037] The oblique core-pulling insert 3 and the positive core-pulling insert 2 are covered with guide blocks 4, which are connected to the mold. The mold includes a fixed mold 21 and a movable mold 22, and the guide blocks 4 are installed on the movable mold 22. After the Y-shaped product 1 is formed, it is inserted into the oblique core-pulling insert 3 and the positive core-pulling insert 2. The oblique core-pulling insert 3 and the positive core-pulling insert 2 are each provided with a plug-in positioning structure 233 to prevent deflection. The plug-in positioning structure 233 is a slot that matches the end of the oblique core-pulling insert 3.

[0038] The slider seat 6 is connected to a travel driving block 9 . The slide seat 7 is provided with a travel driving slot 71 . One end of the travel driving block 9 extends into the travel driving slot 71 .

[0039] The travel drive block 9 can slide back and forth in the travel drive groove 71. When the travel drive block 9 runs to the end of the travel drive groove 71, the travel drive block 9 can drive the slide seat 7 to move synchronously, so that the positive core pulling assembly 31 drives the oblique core pulling assembly 32 to move together.

[0040] The slider seat 6 is provided with a first fixing groove 61 , which is a T-shaped groove. The first fixing groove 61 is connected to the oil cylinder 10 , and the output end of the oil cylinder 10 is embedded in the first fixing groove 61 to drive the slider seat 6 to move.

[0041] The slider seat 6 is provided with a second fixing groove 62 and a third fixing groove 63 . One end of the travel driving block 9 is fixed to the second fixing groove 62 , and the anti-rotation fixing block 5 is fixed to the third fixing groove 63 .

[0042] A side fixing plate 90 is provided on one side of the slider seat 6, and a stop lock block 13 is connected to the side fixing plate 90. A stop lock groove 64 is provided on the slider seat 6, and the stop lock block 13 can be embedded in the stop lock groove 64 to lock the slider seat 6.

[0043] The slider seat 7 is provided with a T-shaped inclined slot 72 , in which a steering T-block 11 is slidably connected. One end of the inclined core-pulling insert 3 is connected to the steering T-block 11 , and the inclined core-pulling insert 3 can slide obliquely with the steering T-block 11 .

[0044] A fourth fixing slot 73 is defined on the slide seat 7 , to which a time-delaying toggle block 12 is fixedly connected. The position of the time-delaying toggle block 12 corresponds to the position of the stop lock block 13 .

[0045] A first inclined surface 121 and a second inclined surface 122 are respectively provided on both sides of the delay toggle block 12 , and a third inclined surface 131 and a fourth inclined surface 132 are respectively provided on both sides of the stop lock block 13 .

[0046] A spring slot 133 is formed on one side of the locking block 13 , and a spring is disposed in the spring slot 133 for providing a locking force.

[0047] The inclined core pulling assembly 32 is connected to an inclined guide column 8, which is installed on the side of the fixed mold 21 and has a stroke of B.

[0048] The oil cylinder 10 and the stop lock block 13 are installed on the movable mold 22 side.

[0049] First, the whole set of actions requires moving the oblique core pulling assembly 32 to separate the in-mold insertion positioning structure, and the positive core pulling assembly 31 needs to be controlled to be temporarily immobilized. A delay toggle block 12 is designed on the oblique core pulling assembly 32 and a stop lock block 13 is installed at the bottom of the positive core pulling assembly 31. When the movable mold 22 and the fixed mold 21 are opened and separated, the bottom stop lock block 13 first locks the positive core pulling assembly 31. When the oblique guide column 8 on the fixed mold 21 side stirs the oblique core pulling assembly 32 to move as a whole to the A stroke position of the delay toggle block 12, the bottom stop lock block 13 opens in advance, with stroke A=B-0.5, and prevents the stroke drive block 9 from stirring the positive core pulling assembly 31. A movement delay is made on the sliding seat 7, with stroke F=B+0.5. The oblique guide column 8 is fixed to the fixed mold 21, and the mold opening action is used to separate the movable and fixed molds to stir the oblique core pulling assembly 32.

[0050] Next, the oil cylinder 10 of the positive core pulling assembly 31 starts to pull the core. The stroke driving block 9 between the positive core pulling assembly 31 and the oblique core pulling assembly 32 is used to drive the oblique core pulling assembly 32 to move synchronously. Since the core pulling stroke B is greater than C, the oblique core pulling insert 3 is prevented from separating from the guide block 4. A delay is made on the sliding seat 7. The stroke E = C-B+2. Figure 12 and Figure 13 .

[0057] E: The stroke of the second mold opening of the inclined core pulling component 32;

[0058] Compared to existing technologies, the Y-shaped product long core-pulling slider mechanism of the present invention utilizes a single hydraulic cylinder 10 and utilizes both the movable and fixed molds for opening and closing, perfectly resolving the problem of action sequence. Furthermore, integrating both actions into the same component saves mold space, simplifies the mold structure, eliminates die-stamping risks, improves production cycle time, and stabilizes product quality. Similarly, the mold closing action can also achieve core feeding by the hydraulic cylinder, and the mold closing and movable molds can be operated without interference.
