Abstract

The invention discloses a quick hoisting type mold changing trolley and a mold changing method thereof. The quick hoisting type mold changing trolley comprises a trolley body, wherein the trolley body comprises a bearing surface and an underbed; the trolley body is provided with an electrical control system for controlling a mold changing process; mounting seats are arranged at two ends of the trolley body; a lifting mechanism is connected between each mounting seat and the trolley body; each mounting seat is arranged in a separate manner, and comprises an upper part and a lower part; a first horizontal translation mechanism is connected between each upper part and the corresponding lower part; each upper part is provided with a mold shifting arm; and a second horizontal translation mechanism is connected between each mold shifting arm and the corresponding upper part. Compared with the prior art, the quick hoisting type mold changing trolley has the beneficial effects that a mold is lifted up through the lifting mechanisms at first, and then moves to the trolley through the translation mechanisms, in a whole process, the bottom surface of the mold does not rub a working table and the trolley, the mold changing process is stable, mold changing time is saved, and mold changing efficiency is improved.

Example Embodiment

[0032] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0033] Such as figure 1 As shown, a quick-lifting type mold changing trolley includes a trolley body. The trolley body includes a bearing surface and an underframe. The underframe is provided with wheels, and the wheels run along the guide rails. The trolley body is equipped with In the electrical control system that controls the mold change process, the electrical control system is equipped with a PLC controller. The two ends of the trolley body along its movement direction are respectively movably connected to a mounting seat, and the mounting seat and the trolley body are connected with a lift The lifting mechanism drives the mounting seat to lift on the trolley body. The mounting seat is set separately and includes an upper branch and a lower branch. A first horizontal translation mechanism is connected between the upper branch and the lower branch. The first horizontal translation mechanism drives the two upper divisions to move closer or apart. The upper division is movably connected with a mold shifting arm, and a second horizontal translation mechanism is connected between the mold shifting arm and the upper division, and the second horizontal translation mechanism drives The mold-moving arm extends or retracts into the trolley body, the cross-section of the mold-moving arm is L-shaped, and the convex steps are arranged facing downwards. Both sides of the mold are equipped with shoulder steps that match the mold-moving arm.
[0034] A first distance sensor is provided on the end surface of the mold-moving arm facing the mold, and the first distance sensor is used to detect the distance between the end surface of the mold-moving arm and the back surface of the mold, and transmit the signal to the PLC controller;
[0035] A second distance sensor is provided on the side of the bearing surface facing away from the punch, and the second distance sensor is used to detect the distance between this side of the bearing surface and the facing surface of the mold, and transmit the signal to the PLC controller;
[0036] A third distance sensor is provided on the clamping surface of the mold-moving arm for clamping the mold, and the third distance sensor is used to detect the distance between the clamping surface and the mold and transmit the signal to the PLC controller.
[0037] The lifting mechanism is a hydraulic cylinder or an air cylinder.
[0038] Both the first horizontal translation mechanism and the second horizontal translation mechanism are hydraulic cylinders or air cylinders.
[0039] The first horizontal translation mechanism and the second horizontal translation mechanism are both rack and pinion motion pairs.
[0040] Both the first horizontal translation mechanism and the second horizontal translation mechanism are ball screw kinematic pairs.
[0041] The mold changing method of the quick-lifting mold changing trolley includes the following steps:
[0042] Step 1. The trolley body moves to the position facing the punching machine table, stops and locks;
[0043] Step 2: The first distance sensor detects the distance between the end surface of the mold moving arm and the back surface of the mold, and transmits the signal to the PLC controller, and the PLC controller issues instructions to control the second horizontal translation mechanism to drive the mold moving arm to extend , When the signal detected by the first distance sensor is the preset value, that is, the mold moving arm moves below the mold shoulder, the PLC controller issues an instruction, and the second horizontal translation mechanism stops driving;
[0044] Step 3. The third distance sensor detects the distance between the clamping surface and the mold, and transmits the signal to the PLC controller. The PLC controller issues instructions to control the first horizontal translation mechanism to move the upper parts of the mounting seat closer to each other. When the signal detected by the third distance sensor is the preset value, that is, the mold moving arm clamps the mold shoulder, the PLC controller issues an instruction, and the first horizontal translation mechanism stops driving;
[0045] Step 4. After the mold-moving arm clamps the mold shoulder, the PLC controller issues an instruction to control the lifting mechanism to raise the mounting seat, and the mold-moving arm will lift the mold;
[0046] Step 5. After the mold moving arm lifts the mold, the PLC controller sends an instruction to control the second horizontal translation mechanism to drive the mold moving arm to retract. When the signal detected by the second distance sensor is the preset value, the mold reaches the load Above the orthographic projection of the surface, the PLC controller issues an instruction, and the second horizontal translation mechanism stops driving;
[0047] Step 6. After the mold reaches the top of the orthographic projection of the bearing surface, the PLC controller issues an instruction to control the lifting mechanism to lower the mounting seat, and the mold shift arm will place the mold on the bearing surface;
[0048] Step 7. The PLC controller issues an instruction to control the first horizontal translation mechanism to separate the upper parts of the mounting seat from each other, and the mold moving arm releases the mold to complete the removal of the mold;
[0049] Step 8. The step of sending the mold to the worktable is opposite to the step of removing the mold.
[0050] Taking the above-mentioned ideal embodiment according to the present invention as enlightenment, through the above-mentioned description content, relevant workers can make various changes and modifications without departing from the scope of the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the content of the description, and its technical scope must be determined according to the scope of the claims.
