Reverse jacking mechanism

Abstract

The invention belongs to the technical field of die-casting dies, and relates to a reverse jacking mechanism. The reverse jacking mechanism comprises a reverse jacking push plate, a reverse jacking rod fixing plate, a reverse jacking rod, a reverse jacking assembly, a guide assembly, a reset rod, a fixed die frame and a fixed die core; the reverse jacking push plate is arranged on the upper end face of the reverse jacking rod fixing plate; a mounting hole is formed in the position, corresponding to the reverse jacking rod fixing plate, of the reverse jacking push plate; the reverse jacking assembly is arranged in the mounting hole; a guide hole for mounting the guide assembly is formed in the position, corresponding to the reverse jacking rod fixing plate, of the reverse jacking push plate in the mounting hole, and the guide assembly is arranged in the guide hole; the reverse jacking rod fixing plate is provided with a reverse jacking rod; and the reset rod is arranged at the position, close to the guide assembly, of the reverse jacking rod fixing plate; and the reverse jacking assembly comprises a reverse jacking support sleeve, a reverse jacking pull rod and a belleville spring which form an assembly whole body, and the assembly whole body is embedded in the fixed die frame. With the reverse jacking mechanism adopted,a product can be smoothly separated from a fixed die during die opening; and a structure that a spring assembly sinks into the fixed die frame is adopted, so that seat plate components are reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to an anti-jacking mechanism and a usage method thereof. Background technique [0002] With the rapid development of the green travel industry, major car companies and new car manufacturers are entering the field of new energy, and the market demand for die-casting products continues to rise. As one of the three major elements of die-casting production, die-casting mold plays an important role in die-casting production, and its stability is the guarantee for the smooth progress of die-casting production. [0003] Whether the die-casting product can be successfully released from the fixed mold is an extremely serious problem that directly affects whether the die-casting process can be carried out, and it is also the primary issue considered in the design and development of die-casting molds. [0004] In order to solve the above problems, the usual practice is to add an ant...

AI Technical Summary

Problems solved by technology

[0005] ①The mold without seat plate cannot realize the function of the reverse jacking mechanism;

[0006] ② Fixed mold seat plate is required, which increases the cost;

[0007] ③ The design of the anti-top mechanism on the fixed mold frame requires a large space, which affects the strength of the mold;

[0008] ④ Spring grooves are designed on the seat plate of the fixed mold, which requires a large thickness of the seat plate and high cost
