Abstract

Disclosed is a mould manufacturing device with a screw thread protection function. The mould manufacturing device with the screw thread protection function comprises a rack (9), a movable male die (8) which is opposite to a female die (91) arranged at the bottom of the rack (9) and is circumferentially fixed and axially movable in a bottom inner cavity (90) of the rack (9), and a connecting bearing column (7). The lower end of the connecting bearing column (7) is connected with the movable male die (8) through a lower elastic connecting part (78). The movable male die (8) and the connecting bearing column (7) are circumferentially fixed through multiple male die extending parts (81) which are fixedly arranged on the upper surface and slidably extend into the connecting bearing column (7). The upper end of the connecting bearing column (7) is connected with a screw thread block (6) through an upper elastic connecting part (76), and the screw thread block is in screw thread fit with the inside of a screw thread sleeve (5).

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a mold manufacturing device with thread protection function. Background technique [0002] In the mold device, some mold pressing mechanisms are often used to drive the movable mold. The driving method often has a hydraulic type and a threaded type. For small-scale molding processing, screw-type driving and pressing can have the advantages of cost reduction and easy maintenance. [0003] The thread fit itself is self-locking, so the pressing down method of this mode can well bear the gravity of the dynamic model and other loads, and make the overall equipment have good stability. [0004] However, since the precision of the thread fit affects the running accuracy and transmission efficiency of the equipment, when the movable mold is subjected to an unexpected impact from the outside, it is easy to transmit the impact load to the thread fit part, which will affect the thread fi...
