Description

Technical Field

[0001] The invention relates to the technical field of mold trial mold assembly, and in particular to a trial mold assembly device for mold processing. Background Art

[0002] Mold trial refers to the test die-casting step performed after the mold is made and before mass production in the product development and manufacturing process. The purpose of mold trial is to evaluate the performance of the mold and product quality, ensure the stability of mass production and optimize process parameters.

[0003] During the manufacturing process of the mold, the mold will be finely processed by EDM before the mold trial. During the EDM process, due to the high temperature and rapid thermal cycle, the surface of the mold workpiece will experience a rapid heating and cooling process, resulting in the redistribution of the internal stress of the material, and residual stress will be generated on the surface and inside the mold. These residual stresses are both tensile and compressive in nature. These residual stresses will remain in the mold in small amounts and accumulate over time;

[0004] Since the residual stress generated by EDM is smaller than the cutting stress and grinding stress in the mold machining process, and the stress relief processing of the die-casting mold requires slow and uniform heating and cooling of large-sized steel parts, which usually takes a long time, some manufacturers will ignore the smaller residual stress after EDM in order to reduce the production cycle of the mold, and directly perform the mold trial step after EDM, and then adjust the mold size after the mold trial, and then perform the final stress relief. However, when the mold is tried under the condition of residual stress, especially the larger molds such as die-casting molds, it is very easy to deform, crack or reduce the fatigue performance of the mold. Therefore, in order to perform rapid stress relief processing before and after the die-casting mold trial, a mold trial assembly equipment for mold processing is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the stress relief processing of the die-casting mold in the prior art requires slow and uniform heating and cooling of large-sized steel parts, which usually takes a long time. In order to reduce the production cycle of the mold, some manufacturers ignore the smaller residual stress after electrospark machining, and directly perform the mold trial step after electrospark machining, and then adjust the mold size after the mold trial, and then perform the final stress relief. However, when the mold is tried under the condition of residual stress, especially the larger molds such as die-casting molds, it is very easy to deform, crack or reduce the fatigue performance of the mold.

[0036] A stress relief groove is provided on the test mold platform 1, and a synchronous control frame 17 is connected to the inner side wall of the stress relief groove, and a heat-averaging hole cover 18 is connected to the inner side wall of the synchronous control frame 17. Access grooves are provided on multiple surfaces of the synchronous control frame 17, and a guide component for controlling the flow of hot air is connected to the inner side wall of the access groove;

[0037] Further, the inner side wall of the top of the stress relief groove on the test mold platform 1 is connected with a folding cover plate 16 through a hinge 15, an air pump for removing mold stress is arranged in the test mold platform 1, the inner side wall of the stress relief groove on the test mold platform 1 is fixedly connected with the side wall of the synchronous control frame 17, the inward side wall of the synchronous control frame 17 is fixedly connected with the outer side wall of the heat equalization hole cover 18, the guide assembly is composed of an adjustment rack 20, a plurality of adjustment gears 21 and a plurality of guide plates 22, the synchronous control frame 17 is fixedly connected with a pneumatic push rod 19, the output end of the pneumatic push rod 19 is fixedly connected with the end of the adjustment rack 20, the adjustment rack 20 is respectively meshed with a plurality of adjustment gears 21, the guide plate 22 is rotatably connected with the inner side wall of the synchronous control frame 17 through the pin shaft arranged through it, and the inner side wall of the adjustment gear 21 is fixedly connected with the outer side wall of the bottom end of the pin shaft;

[0038] It should be noted that: the adjusting mechanical arm 9 in the receiving groove of the movable mold mounting seat 6 and the fixed mold mounting seat 7 is used to push the mounting frame plate 14 toward the middle, thereby pushing out the movable mold seat 2 and the fixed mold seat 3, and then using the hinge 15 to fold and open the folding cover plate 16, and then the movable mold seat 2 and the fixed mold seat 3 are pushed into the stress relief groove of the test mold platform 1 by adjusting the mechanical arm 9. At this time, the air pump in the test mold platform 1 is started to generate airflow, and the airflow becomes hot airflow under the heating of the electric heating wire. This is a conventional method and will not be described in detail. The hot airflow will be synchronously controlled by the control frame 17. The mold is blocked by multiple closed guide plates 22, and then the top of the stress relief groove of the test mold platform 1 is insulated by a heat insulation film. When the mold needs to be stress-relieved, the pneumatic push rod 19 is synchronously started to push the multiple adjustment racks 20 at the same time, and the movement of the adjustment racks 20 will drive the meshing multiple adjustment gears 21 to rotate, and the rotation of the adjustment gears 21 will drive the guide plates 22 to rotate together through the pin shaft, so that the multiple guide plates 22 are opened, and the hot air flow outside the synchronous control frame 17 will flow into the stress relief groove from multiple directions synchronously;

[0039] Further benefits are: different parts of the mold can be heated simultaneously, and the flow direction of the hot air flow can be controlled by synchronously controlling the same-frequency rotation of multiple guide plates 22 in different directions. The hot air flow with variable flow directions is convenient for uniform heating of the complex cavity inside the mold.

The fixed mounting of the movable die seat 2 and the fixed die seat 3 is a prior art and will not be described in detail here. Then, the push-out impeller 11 is driven by a motor to rotate, so that the push-out impeller 11 is separated from the arc-shaped limiting plate 12. Then, the arc-shaped limiting plate 12 is retracted into the positioning circular plate 10 under the action of the reset spring, and the fixed limit between the arc-shaped limiting plate 12 and the limiting groove at the end of the receiving groove is released.

At this time, the air pump in the test mold platform 1 is started to generate airflow, and the airflow becomes hot airflow under the heating of the electric heating wire. This is a conventional method and will not be elaborated. The hot airflow will be blocked by multiple closed guide plates 22 in the synchronous control frame 17. Then, the top of the stress relief groove of the test mold platform 1 is insulated by a heat insulation film. When the mold needs to be stress relieved, the pneumatic push rod 19 is synchronously started to push multiple adjustment racks 20 at the same time , the movement of the adjusting rack 20 will drive the meshing multiple adjusting gears 21 to rotate, and the rotation of the adjusting gear 21 will drive the guide plate 22 to rotate together through the pin shaft, so that the multiple guide plates 22 are opened, and the hot air flow outside the synchronous control frame 17 will flow into the stress relief groove from multiple directions synchronously to complete the simultaneous heating of different parts of the mold, and by synchronously controlling the same-frequency rotation of multiple guide plates 22 in different directions, the flow direction of the hot air flow can be controlled. The hot air flow with variable flow direction is convenient for uniform heating of the complex cavity inside the mold. After the heating and insulation of the mold is completed, by controlling the multiple guide plates 22 to close slowly, the subsequent hot air flow is blocked from entering the stress relief groove, so that the mold can be uniformly cooled at a faster speed, and the stress relief of the mold can be quickly completed;

[0042] After the stress relief of the mold is completed, the mounting frame plate 14 is reset by adjusting the mechanical arm 9, and the positioning circular plate 10 and the arc-shaped limiting plate 12 are used to limit the position. Then, the guide seat 5 on the electric control guide column 4 is used to slide and drive the movable mold mounting seat 6 to move, so that the movable mold seat 2 moves and is assembled with the fixed mold seat 3 for mold trial. The liquid injection pushing mechanism 8 pushes the injection of molten metal to die-cast the components. After the product components after the mold trial are taken out, the size is calibrated. If there is an error in the mold, the mold is pushed out by adjusting the mechanical arm 9 for adjustment processing. In this way, the mold can be quickly stress-relieved before and after the mold trial, and the mold and the movable mold mounting seat 6 and the fixed mold mounting seat 7 on the mold trial platform 1 can be separated and reset without disassembly, so that a series of adjustment operations before and after the mold trial assembly process are more coherent and efficient, thereby reducing the output cycle of the mold.
