Structure of lathe mold

Abstract

This invention relates to the structure of a lathe mold, primarily featuring anti-slip O-rings mounted on the mold base body to secure and prevent slippage of the workpiece material. The lathe mold structure includes a mold base body, a fixing cover, and a universal tailstock ejector head. The mold base body has several annular grooves on its protrusions and is fitted with anti-slip rubber O-rings. The fixing cover has a pressure plate at one end and a locking groove at the other. The universal tailstock ejector head has an ejector pin head at one end with several annular grooves, each groove fitted with an O-ring. The ejector pin head engages with the locking groove of the fixing cover. In use, a hollow workpiece material is fitted onto the protrusion of the mold base body, and the pressure plate of the fixing cover presses and secures the workpiece material. The present invention uses the O-ring of the protruding post of the mold base body to compress the inner diameter of the workpiece material, thereby fixing it to the mold base body and preventing it from falling off during lathe operation; in addition, a universal tailstock ejector pin is provided in the locking groove at the rear end of the fixed pressure cover, so that the fixed pressure cover can move within a certain angle range and prevent the workpiece material from shifting during processing.

Claims

1. A structure for a lathe mold, comprising a mold base body, a fixed pressure plate, and a universal tailstock ejector pin; wherein, A mold base body is provided with a protrusion, on which several annular grooves are formed, and each annular groove is fitted with a rubber O-ring for anti-slip effect; a fixed pressure cover is provided with a top pressure plate at one end and a locking groove at the other end; a universal tailstock ejector head is provided with an ejector pin head at one end, on which several annular grooves are formed, and each annular groove is fitted with a rubber O-ring; when assembling the fixed pressure cover and the universal tailstock ejector head, the ejector pin head of the universal tailstock ejector head is locked into the locking groove of the fixed pressure cover; in use, a workpiece material is fitted onto the protrusion of the mold base body, and then the top pressure plate of the fixed pressure cover is used to press and fix it.

2. The structure of the lathe mold as described in claim 1, wherein, The annular groove on the protrusion of the mold base body is one or more.

3. The structure of the lathe mold as described in claim 1, wherein, The universal tailstock ejector pin has one or more annular grooves on its ejector pin head.
