Description

Reinforcement plate under the hood lock hole-turning plastic mold

technical field

The technical field of the invention is a processing device for a reinforcement plate under a hood lock, and in particular relates to a hole-turning and shaping mold for a reinforcement plate under a hood lock.

Background technique

A reinforcement plate under the hood lock, the structure of which is shown in Figure 5, Figure 6, and Figure 7. Its processing needs to go through four processing steps: blanking-forming-punching-flanging. After the final flanging process is completed , the flanging hole of the lower reinforcing plate is easy to be stuck in the die, and it needs to be taken out manually, which reduces the production efficiency. Flattening increases the production process, and the production cost is high.

Contents of the invention

In view of the above problems, the present invention provides a hole-reversing and shaping mold for the lower reinforcement plate of the hood lock, which can automatically push out the lower reinforcement plate to improve production efficiency and ensure good flatness of the upper surface at the same time.

Its technical scheme is such that the reinforcing plate under the engine hood is locked and turned into a plastic mold, which includes an upper template and a lower template, the upper template and the lower template are connected through guide posts and guide sleeves, and the upper template is equipped with an upper template and a lower template. Die structure, the lower template is equipped with a lower mold structure, characterized in that: the lower mold structure is provided with a jacking structure, the jacking structure includes a jacking plate, a jacking pin and a compression spring, and the jacking pin The upper end of the pin is fixed to the ejector plate, the lower end passes through the lower formwork, and is located between the lower formwork and the ejector plate, and a compression spring is installed on the ejector pin.

It is further characterized by:

The lower mold structure includes a lower fixing plate and a lower backing plate, the lower fixing plate is installed on the lower backing plate, the lower backing plate is fixed on the lower formwork, the lower fixing plate is provided with a forming groove, The notch of the forming groove is provided with flanging and chamfering, and the top material plate is installed in the forming groove;

The upper die structure includes a punch, an upper fixing plate, an upper backing plate and a stripping plate, the punch is installed on the upper fixing plate, the stripping plate is installed on the upper fixing plate, and the upper fixing The plate is installed on the upper backing plate, and the upper backing plate is fixed on the upper formwork;

It also includes a flattening structure, the flattening structure includes a flattened upper insert and a flattened lower insert, and the flattened upper insert is embedded in the upper fixing plate and is located in the longitudinal direction of the punch side, the flattened lower insert is mounted in the lower fixing plate corresponding to the flattened upper insert;

The stripping plate is connected with the upper formwork through a spring.

After adopting the present invention, its beneficial effects are: after the flanging process is completed, the upper and lower molds are separated, and the lower reinforcing plate is automatically ejected from the forming groove under the force of the spring through the ejector plate, which avoids the turning of the lower reinforcing plate. The side hole is stuck in the forming groove and taken out by the operator, which improves the production efficiency. At the same time, the flattening structure is embedded in the mold, which ensures the flatness of the upper surface, reduces the manufacture of additional shaping molds, and reduces the production cost.
