Description

Sectional type unloading die structure

Technical Field

The utility model relates to a mould technical field, more specifically say, relate to a mould structure that sectional type was unloaded.

Background

The mold is a variety of molds and tools used in industrial production for obtaining a desired product in the aspects of injection molding, blow molding, extrusion or forging molding, smelting, stamping, stretching and the like, in short, the mold is a tool for molding an article, the tool is composed of various parts, different molds are composed of different parts, and the processing of the appearance of the article is realized mainly through the change of the physical state of a molded material.

At present, when a workpiece shown in figure 4 is produced in the industry, most of the adopted dies are of an integral unloading structure, the die is difficult to separate from an upper female die after forming, the die is difficult to demold, and a stretched semi-finished product with poor bending resistance is easily crushed in the demolding process, so that the production quality and the economic benefit are influenced. Therefore, it is urgently needed to design a sectional type unloading die structure which can easily complete demoulding and can not damage workpieces.

Through retrieval, a large number of patents have been published on molds for sectional unloading, such as chinese patent application No.: 2019210057466, the name of invention creation is: the application discloses a stretching die structure of a sectional type stripper plate, which comprises a die body, wherein the die body comprises the stripper plate, the stripper plate is divided into a plurality of sectional type stripper plate units according to different processing stations, and stripper plate springs are respectively arranged on the die body corresponding to each section of the stripper plate unit; when the stripper plate unit is a blanking forming work station, the elasticity of the corresponding stripper plate spring is greater than the pressing force, when the stripper plate unit is stretched in the initial station, the elasticity of the corresponding stripper plate spring is greater than the pressing force, and when the stripper plate unit is a subsequent stretching work station, the elasticity of the corresponding stripper plate spring is greater than the discharging force and less than the bending resistance of the semi-finished product of the corresponding process. This scheme sets up the stripper segmentation and matches the spring of corresponding elasticity, can prevent that each process semi-manufactured goods from being crushed, is favorable to obtaining higher surface tension quality, promotes quality and reduce cost.

Also as in chinese patent application No.: 2006100383095, the name of invention creation is: the application discloses a composite stamping die for sheet forming, which comprises a male die, a female die, a material returning mechanism, a positioning mechanism and a die frame, wherein a groove is formed in the working surface of the male die; a boss is arranged at the position, corresponding to the concave die working surface groove, of the upper plane of the stripper plate; when the die is used for stamping, the two plates are overlapped together and are formed by one-time composite stamping. The male die and the female die are in a sectional type, and the whole section of die is formed by splicing a plurality of corresponding groups of male dies and female dies. The scheme not only can effectively solve the problem of elastic deformation of the pressed plate, but also has simple structure, reduces the processing cost and can perform one-time composite stamping on the plate.

Both of the above two schemes are good exploration for the mold with sectional unloading, but there is still room for further improvement, and the research on the mold with sectional unloading in the industry has never been stopped.
