Further, the thickness of the cushion block is smaller than the depth of the cushion block mounting groove.

Further, the difference between the thickness of the cushion block and the depth of the cushion block mounting groove is an ejection stroke.

Furthermore, the ratio of the length of the cushion block to the center distance of the ejector rod is 1.15, so that the ejector rod is prevented from being damaged when the ejecting force of the ejecting device is unbalanced.

Further, the clearance between the ejector rod of the ejection device and the ejection hole of the working table surface is 0.5-1 mm.

Further, the transition base plate is fixed with the workbench through bolts, and a T-shaped bolt groove is formed in the transition base plate and used for being connected with the die.

The utility model has the beneficial effects that: the transition base plate is additionally arranged on the existing working table top and is matched with the ejection device, so that the existing working table top is protected from directly bearing impact load, and the problem that large and complex blanks of the original equipment are difficult to eject is solved by adding the ejection device.

Detailed Description

The transition base plate is additionally arranged on the working table surface of the existing equipment, and the ejection device is additionally arranged to complete the mold stripping of the large complex mold.

Referring to fig. 1-5, in a transition pad and ejector assembly, two pad mounting grooves 7 are formed in a transition pad 1, wherein the two pad mounting grooves 7 are formed in two opposite sides of a quadrangle formed by four ejection holes of a workbench, and the lengths of the pad mounting grooves are greater than the lengths of the two opposite sides of the quadrangle; the ejection device 3 comprises four ejector rods 4 and two cushion blocks 5, the ejector rods 4 are connected with the cushion blocks 5, the four ejector rods are located in four ejection holes of the workbench during use, the two cushion blocks are respectively located in two cushion block mounting grooves, and the ejection of the die 6 is pushed by the ejection device under the action of ejection force, so that the die stripping of the forge piece is completed.

Preferably, the thickness of the spacer 5 is smaller than the depth of the spacer mounting groove.

Preferably, the difference between the thickness of the spacer 5 and the depth of the spacer mounting groove is the ejection stroke.

Preferably, the ratio of the length of the cushion block 5 to the center distance of the ejector rod is 1.15, so that the ejector device is prevented from damaging the ejector rod when the ejection force is unbalanced.

Preferably, the clearance between the ejector rod 4 of the ejection device and the ejection hole of the working table top 2 is 0.5-1 mm.

Preferably, the transition base plate is fixed with the workbench through bolts, and a T-shaped bolt groove is formed in the transition base plate and used for being connected with the mold.

According to the transition base plate and the ejection device thereof, the ejector rod penetrates into the working table top 2 through the transition base plate, and the cushion block and the ejector rod are assembled and used through screws; the existing ejection device of the equipment pushes the transition base plate to be ejected out, and the ejection of the transition base plate pushes the blank to be ejected out, so that the die forging is ejected out.

The thickness of the cushion block is smaller than that of the transition cushion block, the cushion block needs to be placed in the transition cushion block, and the height difference between the cushion block and the transition cushion block is the ejection stroke of the ejection device.
