These are classic cases of mold structure. 12 kinds of angle slider side core pulling mechanism. The video is just a simple schematic. But it can give us a lot of inspiration.
Below is a detailed description of the 12 mold structures.
1.Cylindrical pin type angle slider core-pulling mechanism.
When ejecting, the core is pulled out and the product is ejected by the ejector pin. The angle slider has a chute on both sides. Cylindrical pins are provided on both sides of the mold sleeve for guiding the angle slider.
2.Angle pin type angle slider core-pulling mechanism.
When ejecting, the stripper plate pushes the angle slider. At the same time, the core floats a certain distance. This eliminates the tension of the angle slider on the die bush. Continue to ejector and the part is removed from the core.
3.Guide plate type angle slider core-pulling mechanism.
When ejecting, the angle slider is pushed by ejector pin to complete the core pulling.
4.Roller eject type angle slider core-pulling mechanism.
When the mold is opened, because the plastic part has a large tightening force for the fixed mold core. Therefore, the fixed mold Stripper plate is used to release the plastic part from the core to the movable mold under the action of the spring. When ejecting, the roller contacts the angle slider to reduce friction.
5.Wedge block outer core-pulling mechanism
When the mold is opened, due to the action of the inclined surfaces on both sides of the wedge block, the slider is slid and shaped in the guide groove to complete the core pulling.
6.Angle slider outer core-pulling mechanism.
The ejector plate pushes the angle pin, and drives the slider to move in the oblique direction of the angle pin to complete the split core pulling action. And the plastic part is ejected under the action of the ejector pin.
7.Angle slider core-pulling inside the mold.
The head of the slanting pin is a forming slider, and a slanting hole is in the male mold for reducing friction. The bottom of the slide bar can be provided with a roller, and the slanting bar moves along the inclined hole under the action of the ejector device. The plastic part is ejected while pulling the core.
8.Angle slider discontinuous inner core-pulling mechanism.
After the mold is opened, under the action of the ejector. Move the angle slider along the guide slot of the core. The angle slider is pulled out from the plastic part, and the plastic part can be taken out.
9.Angle slider outer parting.
When the mold is opened, it slides in the groove of the tapered mold sleeve under the action of the push rod. Separate to both sides while rising. The plastic part is also gradually separated from the main core. The limit screw acts as a slider limit.
10.Angle slider stop structure.
When opening the mold, leave the slider in the moving mold. Need to set the stop device. A spring pin is placed between the stationary molds. The pressure of the spring is used to help the angle slider stay in the movable mold.
11.The guiding effect of the main core on the plastic part.
The main core disposed on one side of the movable mold extends into the plastic part to maintain the center position of the plastic part. Let it leave each slider at the same time.
12.Push the slider and plastic parts simultaneously with the stripper plate.
In order to evenly force the plastic part, sometimes the push rod of the pusher is added in addition to the push rod of the push-sliding slider, so that the two move synchronously.
