A powder forming press generally includes an upper box, an upper die mechanism and a lower die mechanism. The upper die lifting drive device of the upper die mechanism is generally installed on the top of the upper box. For example, the powder forming press die frame with an upper independent drive structure disclosed in the invention patent number CN221186930U includes a box, an upper lifting drive device, an upper second lifting drive device, an upper plate, an upper second plate, etc. The upper second lifting drive device and the upper lifting drive device are downwardly arranged at the upper end of the box, the upper lifting drive device and the upper second lifting drive device are arranged side by side horizontally and at the same height, the upper second lifting drive device is connected to the upper second plate, and the upper lifting drive device is connected to the upper plate. The three upper mold lifting drive devices of this patent are all installed side by side on the top of the box. During the operation of pressing the product, the top of the box serves as the force-bearing surface of the upper mold lifting drive device. It will deform after long-term use. Such deformation will cause uneven upper and lower gaps during pressing and closing the mold, which will directly affect the pressing accuracy, size and shape of the product. This deformation may also cause defects such as cracks, breakage or deformation in the product, reducing product quality. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a press structure that helps to reduce the local stress borne by the upper end of the box, avoids deformation of the box due to stress concentration, and improves the molding accuracy of the product.

[0004] To achieve the above-mentioned purpose, the present invention provides a press structure capable of preventing a box from deforming, comprising a box, an upper lifting drive device, an upper second lifting drive device, an upper guide column, an upper fixed plate, an upper guide plate, an upper second guide plate, an upper seat plate, an upper second plate, and an upper plate guide rod. The bottom of the top plate of the box is fixedly connected with a reinforcing connection structure, a columnar channel extending downward from its top surface and passing through the reinforcing connection structure is formed on the top plate, more than two upper guide columns are provided and are respectively fixedly connected between the top plate and the upper fixed plate, the upper guide plate and the upper second guide plates are sequentially installed from top to bottom and are slidably connected with the upper guide column, and the upper two lifting drive devices are installed on the top plate. At the top, the upper two lifting drive devices are connected to the upper two plates through the columnar holes, the upper guide plate, the upper two guide plates and the upper fixed plate through the upper two transmission assemblies and drive them to move up and down. The upper lifting drive device is provided with two and is installed at both ends of the upper guide plate and is respectively located on both sides of the reinforced connection structure. The upper lifting drive devices are connected to the upper two guide plates through their respective corresponding upper two transmission assemblies. The upper plate guide rods are respectively fixedly connected between the upper two guide plates and the upper seat plate after passing through the upper fixed plate and the upper two plates. The upper lifting drive devices can drive the upper two guide plates to move up and down through their respective corresponding upper two transmission assemblies, thereby driving the upper seat plate to move up and down.

[0005] Compared with the prior art, the present invention has the following beneficial effects:

By providing a reinforcing connection structure fixedly connected to the bottom of the top plate at the upper end of the box, the strength of the upper end structure of the box is significantly improved, and the rigidity of the upper end of the box is effectively enhanced. It can provide more stable support for the upper two lifting drive devices installed on the top of the top plate.
