[0016] The utility model discloses a kind of integrated hydraulic device lower beam plate, and it is described in detail below with reference to the drawings.

[0017] Example one:

[0018] As Figure 1 Shown, a kind of integrated hydraulic device lower beam plate is given in the present embodiment, including beam plate body 1, installation cavity 2 is equipped in beam plate body 1, beam plate body 1 includes pedestal 101 and cover plate 102, installation cavity 2 is located in pedestal 101 and installation cavity 2 upper end is formed opening 7 on the upper end surface of pedestal 101, cover plate 102 is connected pedestal 101 and blocks opening 7, the width of opening 7 is greater than the width of installation cavity 2 so that the step surface 8 is formed in pedestal 101, in the present embodiment, since the cross section of installation cavity 2 and opening 7 is circular, the width here refers to diameter, that is, the diameter of opening 7 is greater than the diameter of installation cavity 2, step surface 8 is horizontally arranged, and its height position is between the upper end surface of pedestal 101 and the inner bottom end, the bottom end of cover plate 102 is in abutment with step surface 8, cover plate 102 and pedestal 101 are fixed by bolt 9, specifically, bolt 9 is fixed through step surface 8 and pedestal 101, the bottom end of cover plate 102 is provided with protruding part 10, the side wall of protruding part 10 is in abutment with the inner wall of installation cavity 2, that is to say, protruding part 10 is inserted into installation cavity 2.

[0019] As Figure 1 Shown, installation cavity 2 is connected with the first oil cylinder 3 for providing upward pressure to product to make product deformation and the second oil cylinder 4 for ejecting product, the first oil cylinder 3 is connected with push rod 5, the second oil cylinder 4 is connected with ejector rod 6, push rod 5 and ejector rod 6 are all arranged upward and pass through the upper end of beam plate body 1, push rod 5 extends out of beam plate body 1 and contacts with lower mould to exert upward pressure, similarly, ejector rod 6 extends out of beam plate body 1 and ejects product, specifically, push rod 5 and ejector rod 6 all pass through the upper end of cover plate 102.

[0020] As Figure 1 Shown, the first oil cylinder 3 is annular plunger type oil cylinder, the second oil cylinder 4 is piston type oil cylinder and is located in the center hole of the first oil cylinder 3, push rod 5 is columnar and annular distribution, ejector rod 6 is also located in the center hole of push rod 5, since ejector rod 6 and push rod 5 all pass through cover plate 102, ejector rod 6 and push rod 5 are still separated by cover plate 102;And installation cavity 2 is provided with annular partition plate 11, annular partition plate 11 is integrally formed with beam plate body 1, specifically, annular partition plate 11 is connected at the inner bottom end of pedestal 101, and is integrally formed with pedestal 101, the first oil cylinder 3 is fixedly connected between the outer peripheral wall of annular partition plate 11 and the inner wall of installation cavity 2, and the second oil cylinder 4 is fixedly connected in the inner peripheral wall of annular partition plate 11.

[0021] The lower beam plate is used in a hydraulic device. The first oil cylinder 3 can drive the push rod 5 to move vertically. When the push rod 5 moves upward, it can output pressure from bottom to top, which is applied to the lower mold above the lower beam plate. This provides pressure from bottom to top to the product during the molding process. For example, in some wheel hub molding processes that require greater molding pressure, the pressure of the upper mold is limited. When the upper mold is pressed down, the first oil cylinder 3, in conjunction with the pressure of the upper mold, can provide greater pressure to the product to press and form it, meeting the usage requirements. After the product is pressed and formed, the second oil cylinder 4 ejects the product through the ejector rod 6.
