Description

Side pressing mechanism of automobile fender flanging shaping mold

technical field

The utility model relates to a fender pressing mold, in particular to a side pressing mechanism of an automobile fender flanging shaping mold.

Background technique

At present, when designing molds for flanging the fenders of automobile panels, the flanging angle is too large, and a self-made wedge mechanism is usually used to realize the flanging. When the mold is working, when the angle of the side flange is too large, the positive pressure plate of the mold will not be able to press the material locally, resulting in poor forming quality of the plate.

Utility model content

The technical problem to be solved by the present invention is: to provide the block side pressing mechanism of the fender flanging plastic mold of the automobile cover, the pulley side pressing mechanism of the fender flanging shaping mold of the automobile cover overcomes the above-mentioned problems There are deficiencies in technology, and it is a mechanism with high molding quality, short manufacturing cycle and low manufacturing cost.

In order to solve the existing problems in the background technology, the utility model adopts the following technical scheme: the side pressing mechanism of the automobile fender flanging shaping mold, which includes a lower mold body, and a punch is provided on one side of the lower mold body , the lower mold body is provided with a groove, the groove is provided with an upper mold body, the upper mold body is provided with a wedge body on one side, and one end of the wedge body is provided with a side The clamping plate, the side clamping plate and the wedge body are fixedly connected by a wedge clamping plate, the punch is set at the bottom of the side clamping plate, and the punch and the wedge body are fixedly connected. There is a working knife block between them.

Preferably, the upper mold body and the wedge body are vertically connected through a wedge surface.

Preferably, a nitrogen gas spring is provided in the groove, and the bottom of the oblique wedge body is connected with the nitrogen gas spring.

Preferably, the top of the convex mold is the placement surface of the fender, and a concave-convex arc mold that cooperates with each other is provided between the convex mold and the working knife block.

The working principle of the utility model is that the side pressure material core mechanism of the fender flanging shaping mold of the automobile cover part includes a convex mold installed on the lower mold body, a wedge drive block and the upper mold body are cast as one, the middle wedge clamping plate, The integral structure of the side pressing material block, the working knife block and the wedge body is the moving part. The mold starts to close the mold, the upper mold body and the wedge body slide to drive the wedge body to start moving in the stamping direction, the side pressing material block is first pressed with the punch to press the surface of the plate with an excessive angle, the wedge clamping plate and The wedge body begins to guide so that the pressing force is well transmitted to the plate, and finally the working knife block contacts the plate to complete the forming quality requirements of the required parts. The mold is opened, and the return force provided by the nitrogen spring at the bottom of the wedge body makes the moving part return to its original state, completing a forming cycle of the plate.

To sum up, the utility model has the following advantages: the pulley side pressing mechanism of the automobile panel fender flanging shaping mold can ensure the molding quality, optimize the production of the mold and the plate, and use the nitrogen spring at the bottom of the wedge body to The return force provided makes the moving part return to the original state, completes a forming cycle of a plate, realizes flanging and shaping, improves the forming quality, and avoids the workload of repeatedly debugging the plate here.

detailed description

Referring to the accompanying drawings, the side pressure mechanism of the automobile fender flanging plastic mold includes a lower mold body, a punch is provided on one side of the lower mold body, and a groove is arranged in the lower mold body, so that An upper mold body is provided in the groove, a wedge body is provided on one side of the upper mold body, and a side clamping plate is provided at one end of the wedge body, and the side clamping plate and the wedge The bodies are fixedly connected by a wedge clamping plate, the punch is set at the bottom of the side hold-down plate, and a working knife block is set between the punch and the wedge body.

Preferably, the upper mold body and the wedge body are vertically connected through a wedge surface.

Preferably, a nitrogen gas spring is provided in the groove, and the bottom of the oblique wedge body is connected with the nitrogen gas spring.

Preferably, the top of the convex mold is the placement surface of the fender, and a concave-convex arc mold that cooperates with each other is provided between the convex mold and the working knife block.

The side pressure core mechanism of the fender flanging shaping mold for automobile panels includes a punch installed on the lower mold body, a wedge driving block and the upper mold body cast as one, a middle wedge clamping plate, a side pressure material block, and a working knife block The structure integrated with the wedge body is the moving part. The mold starts to close the mold, the upper mold body and the wedge body slide to drive the wedge body to start moving in the stamping direction, the side pressing material block is first pressed with the punch to press the surface of the plate with an excessive angle, the wedge clamping plate and The wedge body begins to guide so that the pressing force is well transmitted to the plate, and finally the working knife block contacts the plate to complete the forming quality requirements of the required parts.
