Description

A mold that is easy to demould

Technical Field

The utility model relates to the field of molds, in particular to a mold which is convenient for demoulding.

Background Art

A mold is a tool that uses a specific shape to form a blank into a product with a certain shape and size under the action of an external force. The mold is extremely widely used in forging, stamping, powder metallurgy pressing, pressure casting, and compression and injection molding of engineering plastics, rubber, ceramics and other products. The mold is generally divided into two parts, which are divided into a movable mold and a fixed mold according to the motion state, and into a concave mold and a convex mold according to the shape.

At present, in the production and processing of workpieces, stamping dies are needed for stamping processing. However, after the current stamping dies have completed stamping the workpiece, they do not have a structure for demolding the stamped workpiece. The demolding speed of the stamped workpiece inside the die is slow, which in turn reduces the stamping speed of the die. Therefore, we propose a die that is easy to demold to solve the above problem.

The purpose of the utility model is to provide a mold that is easy to demould, so as to solve the problems raised in the above background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions:

A mold for convenient demoulding comprises a lower mold, an upper mold is arranged above the lower mold, the bottom surface of the lower mold is fixedly connected to a support cover, the bottom surface of the lower mold is fixedly connected to two electric cylinders, the bottom surface of the lower mold is provided with a through hole, the bottom ends of the two electric cylinders pass through the through hole and extend to the inside of the support cover, the telescopic ends of the two electric cylinders are fixedly connected to a connecting plate, the interior of the lower mold is provided with two cavities, the inner bottom walls of the two cavities are provided with sliding holes, the inner walls of the two sliding holes are slidably connected with slides, the side surfaces of the two slides that are close to each other are respectively fixedly connected to the side surfaces of the two connecting plates that are away from each other, the upper surface of the lower mold is provided with a mold groove, and the inner bottom wall of the mold groove is provided with two demoulding holes.

In a further embodiment, the upper surfaces of the two slides are fixedly connected to limiting plates, the upper surfaces of the two limiting plates are fixedly connected to stripping plates, and the top ends of the two stripping plates extend to the inside of the two stripping holes respectively.
