One-step forming and automatic demolding mold for hollow grid product

Abstract

The invention discloses a one-step forming and automatic demolding mold for a hollow grid product. The mold comprises an upper mold, a lower mold, a mold core, and a demolding mechanism, wherein the demolding mechanism comprises a connecting seat connected with the tail end of the mold core, an ejector rod connected with the connecting seat, a pushing handle which is accommodated in the connectingseat and used for pushing the product away from the mold core, and a driving air cylinder which drives the pushing handle to act. In the demolding process, the upper mold and the lower mold are separated, the ejector rod pushes the mold core to rise to enable the mold core to be separated from the lower mold, the air cylinder drives the pushing handle to push the formed product away from the moldcore, and automatic demolding is realized. The mold disclosed by the invention is specially designed for the forming characteristic of hollow grid products, and on the premise of ensuring the one-step forming of the product, the full automatic demoulding is realized, therefore the processing efficiency is greatly improved and the processing cost is reduced. The mold further has the advantages that by changing the design of a traditional demolding structure, the demolding stroke is shortened, and the occupied space of the mold is reduced, the problem that a hollow product is prone to damage inthe demolding process is solved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of mold design, in particular to an automatic demoulding mold for one-time molding of hollow grid products. Background technique [0002] With the development of injection molding technology, some products with complex structures can be molded by injection molding, but currently for some products with special structures, such as figure 1 As for the hollow mesh product 100 shown, the existing mold is difficult to achieve one-time molding, even if it is formed, it cannot realize automatic demoulding, which greatly reduces the processing efficiency and increases the processing cost. Moreover, due to its structural characteristics, the hollow product adopts a general demoulding mechanism design, which also has the problem that the demoulding stroke is too long, and demoulding is likely to cause structural damage to the product. [0003] Therefore, the prior art needs to be further developed and improved. Contents of th...
