Embodiment Construction

[0012] Embodiments of the present invention: as attached figure 1 As shown, it is composed of the mold core sleeve 1, the ejector pin 2 and the die sleeve 3, the mold core sleeve 1 is connected with the mold core 6 installed in the die 5 through the screw pair 4, and the screw pair 4 adopts a conventional screw The auxiliary mechanism is installed to realize the conversion of linear motion and rotary motion. In order to ensure that when the ejector pin 2 pushes the mold core sleeve 1, the mold core sleeve 1 can only move in the axial direction, the mold core sleeve 1 is also connected with the die sleeve 3 through the moving pair 7, and the moving pair 7 adopts a conventional moving pair mechanism to install. For ease of installation and operation, a backing plate 8 is also installed at the bottom of the die sleeve 3, and the top of the ejector rod 2 passes through the backing plate 8 and pushes against the bottom of the mold core rotary sleeve 1.

Abstract

The invention discloses a demoulding method of a precise forming component and a device thereof, wherein, the method is that a mould core of a mould is first rotated correspondingly to the forming component, so as to eliminate the adhesive force between the forming surface of the forming component and the mould core, then the forming component is pushed out from a mould cavity of the mould, thereby finishing the process of demoulding; the demoulding device consists of a mould core rotary sleeve (1), a mandril (2) and a concave mould sleeve (3), wherein, the mould core rotary sleeve (1) is connected with the mould core (6) that is arranged in a concave mould (5) by a spiral pair (4); the mould core rotary sleeve (1) is connected with the concave mould sleeve (3) by a moving pair (7); the top end of the mandril (2) props up the bottom of the mould core rotary sleeve (1). Compared with the prior art, the invention has the advantages of high forming precision, simple structure, reliable action, good strength, long service life and high efficiency, and the like, thereby greatly reducing the waster ratio and the production cost of enterprises.

Description

technical field [0001] The invention relates to a method and a device for separating a formed part from a mold, in particular to a method and a device for releasing a precision formed part. Background technique [0002] For precision-formed parts with thin-walled spherical hole structure characteristics, when demoulding, the method of ejection along the axial direction is generally used for demoulding. Due to the uneven force on the forming surface of the parts when they are ejected, it is easy to cause local deformation of the parts, and it is difficult to ensure the dimensional accuracy of the parts, resulting in an increase in the scrap rate and increasing the production cost of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a demoulding method and a demoulding device for precision formed parts that are not easily deformed during demoulding and have high forming precision, so as to overcome th...
