[0103] Step 5: pre-tighten the bolts at the second assembly station 53 using a torque wrench;

[0104] Step 6: At the platform assembly station 55, first, the electromagnetic platform 2 is loaded on the platform assembly conveyor line 54 and the limit protection block 3, the ejection electronic ruler 4, the positioning electronic ruler 7 and the assembly control box 8 are assembled in sequence; then, at the platform assembly station 55, the pre-assembled electromagnetic platform 2 is installed above the ejection plate 10 and connected to the bottom plate 14 through the support column 1 and the guide column 9 respectively;

[0107] The injection mold pre-ejection machine of the present invention is mainly used for the ejection pre-inspection of the injection mold. Before the mold is put into the injection molding machine for mold trial, the ejection condition of the mold and the action effect of each part during ejection can be checked, thereby reducing the dependence on the injection molding machine and saving the mold trial cost.

[0108] The uses of this device are:

[0109] Power on the pre-ejection machine, use the remote control 16 to start the positioning electronic ruler 7, draw a line on the electromagnetic platform 2, set the shape positioning area of ​​the pre-ejection mold, and set the ejection position 6 according to the mold ejection requirements; at this time, the operator operates the crane to lift the mold above the pre-ejection machine and place the mold according to the drawn area;

[0110] Use the remote controller 16 again to magnetize the electromagnetic platform 2 to fix the mold;

[0111] Use the 16 remote controller to set the mold pre-ejection height, and the ejection electronic ruler 4 controls the ejection distance;

[0112] Use the remote controller 16 to start the ejection oil cylinder 12 to push the ejection plate 10 and drive the ejection rod 6 to eject;

[0113] Use the 16 remote controller to push out and reset, and the electromagnetic platform 2 is demagnetized, thus completing a circuit.

[0114] The equipment of the present invention can perform pre-ejection operation for molds below 1000 tons. Since the ejection holes of each set of molds are different, 29 ejection holes are designed. The ejector rod 6 of each hole can be quickly disassembled and assembled, and each ejector rod 6 has a set of ejector rod lock buckles 5 for control.

[0115] All signal instructions of the remote controller 16 are compiled by the assembly control box 8 and sent to each functional area.

[0116] The pre-ejection machine of the present invention adopts intelligent control, digital drawing and data ejection, which greatly facilitates the operation of employees. The mold is conventionally fixed by a pressing plate, especially when the injection molding machine is injecting, a pressing plate is also used for fixing. This wastes a lot of operator time. It takes at least half an hour to put on the pressing plate, tighten the screws, and fix a set of molds. The present invention adopts intelligent control, and the mold dimensions are input by the remote control. The electronic ruler directly draws lines on the platform. The operator only needs to place it according to the position, and then the electromagnetic platform controlled by the remote control can realize free locking of the mold, which saves a lot of manpower and time. At the same time, pressing plates, screws, screw wrenches and tool boxes are not needed.

[0117] During the pre-ejection test, it is also controlled by a remote control. Only the mold ejection size needs to be input. The operator can get close to the electromagnetic platform to observe the mold ejection process and mold matching conditions, thereby reducing problems during injection molding.

[0118] 80% of the problems in the first mold test are concentrated in the rear mold part, and 60% of the problems in the rear mold are related to ejection. The support pin, inclined ejector, spring plate, retraction and other structures need to be dynamically tested. It is necessary to test the opening and closing smoothness of the single piece and the entire assembly, as well as the stroke problem. These are problems that are not easy to find during the research and fitting by the fitter. With the pre-ejection machine, the above problems can be avoided.

[0119] The present invention realizes the batch automatic production of the pre-pushing machine and reduces the assembly error caused by manual operation.
