Vacuum hot press with multiple protection structure

Abstract

This utility model discloses a vacuum hot press with multiple protective structures, including a base plate, a cover at the top of the base plate, and a vacuum pump fixedly connected to the left side of the top of the cover. The input end of the vacuum pump passes through the top of the cover and extends into the interior of the cover. This vacuum hot press with multiple protective structures, by incorporating the cover, protective cover, mounting ring, and reinforcing layer, provides protection during hot pressing. When the second hot pressing die descends to cooperate with the first hot pressing die in extruding the material, the protective cover outside the second hot pressing die descends along with it and covers both the second and first hot pressing dies, preventing material from flying out during breakage. Furthermore, the reinforcing layer fixed inside the cover effectively increases its strength, further enhancing the protective effect and preventing damage to the main body of the device during hot pressing. This solves the problem of ineffective protection.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the vacuum hot press with multiple protective structures not only achieves effective protection and automatic control device switching, but also improves the stability of the hot pressing mechanism during operation.

[0016] By setting up a cover, a protective cover, a mounting ring, and a reinforcing layer, during hot pressing, when the second hot pressing die descends to work with the first hot pressing die to extrude the material, the protective cover outside the second hot pressing die descends along with the second hot pressing die and covers the outside of the second and first hot pressing dies, which can play a protective role and prevent the material from flying out when it breaks apart.

[0017] By setting up a machine cover, fixing frame, limiting post, connecting plate, cylinder, fixing ring, sealing ring and limiting cylinder, during processing, the cylinders on both sides are first started to push the machine cover up through the connecting plate. After the machine cover is raised, it is easy to add materials. Then the cylinder is started again to drive the machine cover down through the connecting plate, so that the sealing ring at the bottom of the machine cover fits against the top of the base plate to ensure sealing. The fixing ring at the top of the base plate fits against the outside of the machine cover to position the machine cover and ensure its stability. The limiting cylinder at the bottom of the connecting plate fits against the outside of the limiting post to limit the machine cover. This realizes the automatic control device opening and closing.

[0018] By incorporating a second hot press mold, a second heating chamber, a limiting sleeve, a hydraulic cylinder, and a fixed sleeve, during hot pressing, a vacuum pump is first activated to evacuate the inside of the machine casing. Then, the hydraulic cylinder is activated to drive the second hot press mold downwards through the second heating chamber to cooperate with the first hot press mold in extruding the material inside. The fixed sleeve at the top of the second heating chamber fits inside the limiting sleeve, effectively limiting the second heating chamber and ensuring the stability of the second hot press mold during hot pressing. This improves the stability of the second hot press mold during hot pressing, thus ensuring the pressing effect. Attached Figure Description

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during processing, the cylinders 16 on both sides are first activated to push the machine cover 5 up through the connecting plate 15. After the machine cover 5 is raised, it is convenient to add materials. Then, the cylinders 16 are activated again to drive the machine cover 5 down through the connecting plate 15, so that the sealing ring 20 at the bottom of the machine cover 5 is attached to the top of the base plate 1 to ensure sealing. The fixing ring 19 at the top of the base plate 1 is attached to the outside of the machine cover 5 to position the machine cover 5 and ensure its stability.
