Mesh demoulding mechanism

Abstract

The invention discloses a mesh surface demolding mechanism comprising a slide block (1) slidably connected to a mould and an oil cylinder (2) fixedly arranged on the mould, wherein a piston rod of the oil cylinder (2) is connected with the slide block (1), and the slide block (1) is provided with an inner cavity (3) in which an ejector retainner plate (4) is slidably connected; the mould is provided with a locking mechanism for locking the ejector retainner plate (4); an unlocking mechanism controlled by the stroke of the slide block (1) is arranged between a locking block (7) and the slide block (1); inward depressions (11) are formed in two sides of the slide block (1), through holes (12) are also formed in two sides of the slide block (1) and are communicated with the inner cavity (3), and the sides, close to the oil cylinder (2) of the through holes (12), are overlapped with the middles of the inward depressions (11); and the ejector retainner plate (4) is provided with limiting blocks (13) corresponding to the through holes (12) one to one, and the limiting blocks (13) are located in the through holes (12). Compared with the prior art, the mesh surface demolding mechanism has the characteristics that the success rate for demolding mesh surface products is greatly increased, and the product cost can be greatly reduced.

Description

technical field [0001] The invention relates to a demoulding mechanism, in particular to a mesh demoulding mechanism used for demoulding thin-walled mesh products. Background technique [0002] Thin-wall mesh products market products with a wall thickness less than 3mm, and currently there is no demoulding mechanism for such products. A similar technology in the prior art, such as CN 201220660510.8, discloses a double-slider secondary core-pulling mechanism for grid tray injection molds, which is characterized in that it includes a movable template, and the movable template is provided with a first slider. A slider is provided with a core-pulling slider, the core-pulling slider is fixed to the oil cylinder connecting block, the oil cylinder connecting block is driven by the piston rod of the first oil cylinder, and the first oil cylinder is installed on the movable template , a first limit block is fixed on the first slider, a first limit groove matching the first limit blo...

Problems solved by technology

A similar technology in the prior art, such as CN 201220660510.8, discloses a double-slider secondary core-pulling mechanism for grid tray injection molds, which is characterized in that it includes a movable template, and the movable template is provided with a first slider. A slider is provided with a core-pulling slider, the core-pulling slider is fixed to the oil cylinder connecting block, the oil cylinder connecting block is driven by the piston rod of the first oil cylinder, and the first oil cylinder is installed on the movable template , a first limit block is fixed on the first slider, a first limit groove matching the first limit block is formed on the bottom surface of the core-pulling slider, and a first limit groove is fixed on the movable template. Two limit blocks, the bottom surface of the first slider is formed with a second limit groove that matches the second limit block; but this core-pulling mechanism is also for products with thicker walls. When used on the mesh surface of wall parts, due to the small wall thickness, during the demoulding process, since there is no mesh surface and no support, and there is still a certain temperature, the mesh surface is prone to deformation, and even the mesh surface cracks Case

Therefore, there is a problem that the demoulding success rate is low in the prior art, which leads to higher product cost.
