Abstract

The utility model discloses a pneumatic ejector structure of a mould. By means of the pneumatic ejector structure of the mould, the ejector structures for disk-shaped type products are simple and cost of the mould is reduced. The pneumatic ejector structure of the mould comprises a front mould core, a back mould core and a flow passage, wherein a mould cavity is formed between the front mould core and the back mould core and a product is arranged inside the mould cavity. The pneumatic ejector structure of the mould is characterized in that an ejector cavity body is arranged on the upper surface of the back mould core, an upper end face of an ejector block is attached to the lower surface of the product, a return spring is arranged between a lower end face of the ejector block and a bottom end face of a base, an air cavity body is formed between the ejector block and the base in an enclosed mode, the base is placed inside the ejector cavity body, a compression air passage is arranged on the back mould core, compression air passes through the compression air passage and the compression air passage is communicated to the air cavity body.

Description

A kind of pneumatic ejecting structure of mould
Technical field
The utility model relates to the technical field of injection mould mould structure, is specially a kind of pneumatic ejecting structure of mould.
Background technology
The ejecting structure of existing mold is all thimble structure, for the plate-like based article, and the complex structure of this kind ejecting structure, and increased the cost of mould.
Summary of the invention
For the problems referred to above, the utility model provides a kind of pneumatic ejecting structure of mould, and it makes the ejecting structure of plate-like based article simple, and has reduced the cost of mould.
a kind of pneumatic ejecting structure of mould, its technical scheme is such: it comprises front cavity, rear cavity, runner, described front cavity, form die cavity between rear cavity, described runner is communicated with described die cavity, be product in described die cavity, it is characterized in that: described rear cavity upper surface is provided with and ejects cavity, the lower surface of the described product of upper surface applying of angled slide block, be provided with back-moving spring between the lower surface of described angled slide block and the bottom of base, described angled slide block, surround the air cavity between base, described base is positioned at the described inside cavity that ejects, be provided with the Compressed Gas passage on described rear cavity, Compressed Gas passes into described Compressed Gas passage, described Compressed Gas channel connection is to the air cavity.
After adopting said structure of the present utility model, after the goods injection moulding is completed, compressed air passes into the Compressed Gas passage, promoting angled slide block by compressed air ejects goods, after goods ejected, compressed air was closed, and angled slide block resets under the effect of spring, it makes the ejecting structure of plate-like based article simple, and has reduced the cost of mould.
