Description

Fool-proof mold

Technical Field

The utility model relates to a mould injection technical field, concretely relates to prevent slow-witted mould.

Background

The die is a tool for making a blank into a finished piece with a specific shape and size under the action of external force, is used for manufacturing a formed article, and is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy piece pressing, pressure casting, and compression molding or injection molding processing of products such as engineering plastics, rubber, ceramics and the like. Fool-proofing is to prevent a stiff person from doing mistakes, and in the design of the mold, the insert, the mold core and the like are not fool-proofing and can cause errors and losses of different degrees.

Therefore, in the development stage of the mold, the production safety and mistake proofing (preventing production safety accidents caused by wrong operation) can be effectively realized through the asymmetric design (namely, reversion proofing) or the special mark of the mold structure. In the prior art, because the positive and negative of mould is difficult to be discerned for the mould, at the in-process of die-filling, can not distinguish the positive and negative of mould fast usually, in addition, also leads to the mould designer to repair the mould and need check the position through the drawing and just can distinguish the positive and negative of mould, thereby influence production efficiency. In the subsequent process, the front and the back of the mold cannot be distinguished from the front and the back of the forklift driver fork mold and the front and the back of the clamped bun driver frame mold, so that the fork mold and the frame mold are inconvenient to use.

In the existing fool-proof mold, as the fool-proof mold structure disclosed in CN204747251U, although the mold has a certain fool-proof function, the structures of the upper and lower supporting plates, the upper and lower cushion blocks, etc. in the upper and lower mold structures of the mold are similar, so that the mold is easy to be confused when being installed and only distinguished from the appearance quickly, and when the upper mold structure or the lower mold structure is assembled and connected alone, the front and back sides and the front and back sides of parts are easy to be confused. In addition, when the upper die structure and the lower die structure are used for stamping product elements, the possibility of weak bearing capacity and even breakage can occur, and the structure is not stable and firm enough, so that the service life of a die for production is shortened, and the die structure is frequently replaced to increase the production cost.
