Embodiment Construction
[0026] refer to Figure 1-Figure 5 The embodiment of the in-mold cutting device and its process in the present invention will be further described.
[0027] Such as Figure 1-Figure 5 As shown, the present embodiment is an in-mold cutting device in an internal high-pressure forming equipment, which includes an internal high-pressure mold made of die steel, and the internal high-pressure mold includes an upper mold 1 and a lower mold, wherein the lower mold The mold is fixed on the ground or on the working table, and the upper mold is fixed on the press. The upper mold can move closer to or separate from the lower mold under the drive of the external press 3. A cavity is opened on the lower surface of the upper mold. A mold cavity is also opened on the upper surface, and the mold cavities of the upper mold and the lower mold are facing each other, and when the upper and lower molds are closed, the mold cavity 13 can be formed by the above two mold cavities, and the size of the...

Abstract
The invention discloses an in-mold cutting device in internal high-pressure forming equipment and a process thereof. The device has a principle as follows: a special cutting mechanism is arranged in an internal high-pressure mold; during working, the internal high-pressure forming is firstly performed for a workpiece by using internal high hydraulic pressure; then, a driving motor or a hydraulic cylinder drives a punch to punch out an incision in the surface of the workpiece; and a cutter extends into the incision, and is driven to quickly press downwards to cut off the workpiece. Compared with a traditional sawing process, the device and the process have no need to frequently replace a high-precision saw blade, so that the cost is saved; and meanwhile, the cutting is directly performed in a mold, so that the working efficiency is greatly improved.
Description
technical field [0001] The invention relates to an in-mold cutting device and a process thereof in an internal high-pressure forming equipment. Background technique [0002] In the prior art, the steps of the internal high pressure forming of the workpiece are as follows: step 1, blanking, step 2, blank making, step 3, assembly and welding, step 4, mold clamping, step 5, pressing into the mold, step 6, mold Internal high pressure forming, step seven, taking parts after internal high pressure forming, step eight, cutting formed parts. [0003] The cutting of the workpiece needs to open the mold first, take out the workpiece and then re-clamp and fix it on the cutting machine, and then cut with a high-precision saw blade. On the one hand, this process is cumbersome and time-consuming, which reduces work efficiency. On the other hand, the sawing process wears a lot on the tool. When cutting a large number of workpieces, a lot of saw blades will be lost, increasing the product...
