Abstract
The utility model relates to the technical field of mould push-out devices, and specifically discloses an air-assisted push-out mould. The air-assisted push-out mould comprises an air inlet pipe, a sealing ring sealing ring, a ventilating casting insert and a mould, wherein the side surface of a mould casting insert is provided with the ventilating casting insert, the inner side of the mould is provided with the air inlet pipe, and a joint of the air inlet pipe and the mould is provided with a sealing ring. The air-assisted push-out mould provided by the utility model has the advantages that a product is demoulded, air inflows so that the product and the mould are separated, the push-out resistance is reduced, and therefore, a top convex phenomenon is not generated.
Description
Technical field
The utility model relates to the mold liftout attachment technical field, the auxilliary mould that ejects of a kind of specifically gas.
Background technology
In the mould ejecting structure, it is more widely that pneumatic jack is used, the mould structure of existing conventional pneumatic jack, and demoulding difficulty, analyze its main cause and be:
1, whole circle position of bone highest point is greater than 90mm on the product-forming, and the demoulding angle of two side is less, has only 0.2 degree, also has bottom surface many ribs that distribute simultaneously, and structure has just determined the difficult demoulding of product.
2, use the TPO plastic rubber material on the product material, softer, the sticking to mould tool, die surface the rough and smooth all can increase knockout press, and die surface is too coarse, and frictional force is big when ejecting, and ejects difficulty; Die surface is smooth, and product applying die surface forms vacuum, ejects also difficulty, so the roughness of die surface needs strict control, but still has the problem that ejects difficulty.
3, dark cavity segment in the middle of the ejecting structure, because of topology requirement such as oblique top is arranged, can not do looses core earlier ejects again, uses conventional thimble ejecting block, and because of plastic material is softer, increasing ejects area as far as possible, with big thimble and ejecting block.But the position of bone is too dark, even adopt big jacking block, it is existing to still have the top to protrude, and muscle and appearance are bad, use conventional pneumatic jack, and product bottom surface wall thickness has a circle to have only 1mm, can blow distortion to 1mm place during air inlet even pops, and the problem of ejecting can not get solution.
Therefore, design a resistance that ejects and reduce, do not have the auxilliary mould that ejects of a kind of gas that the top shows elephant especially, just inventor's problem that will face for overcoming above-mentioned deficiency.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides that a kind of gas is auxilliary to eject mould, and it is simple in structure, and is easy to use, ejects resistance and reduce when ejecting mould, does not have the top and shows especially and resemble, and extraordinary practical value is arranged.
The technical scheme that its technical problem that solves the utility model adopts is: the auxilliary mould that ejects of a kind of gas, comprise air inlet pipe, sealing ring, ventilative mold insert, mould, it is characterized in that: described side at inlaid piece of mould is provided with ventilative mold insert, the mould inboard is provided with air inlet pipe, and air inlet pipe and mould joint are provided with sealing ring.
The beneficial effects of the utility model are:
1, the utility model product stripping begins action, and air inlet is opened product and mold separation, ejects resistance and reduces, and does not therefore just have to push up to show especially to resemble.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-air inlet pipe; The 2-sealing ring; The 3-mold insert of breathing freely; The 4-mould.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.
Fig. 1 ejects the mould structure schematic diagram for a kind of gas of the utility model is auxilliary, comprise air inlet pipe 1, sealing ring 2, ventilative mold insert 3, mould 4, described side at mould 4 mold inserts is provided with ventilative mold insert 3, mould 4 inboards are provided with air inlet pipe 1, air inlet pipe 1 is provided with sealing ring 2 with mould 4 joints, product stripping of the present invention begins action, air inlet pipe 1 air inlet, product and mould 4 are separated, therefore eject resistance and reduce, do not have the top and show especially and do not resemble, gas is auxilliary to eject and is applicable to that the plastic cement mould is auxiliary and ejects, strong to absorption affinity, the plastic material that easily sticks to die surface is particularly suitable.
Claims (1)
1. a gas is assisted and is ejected mould, comprises air inlet pipe, sealing ring, ventilative mold insert, mould, and it is characterized in that: described side at inlaid piece of mould is provided with ventilative mold insert, and the mould inboard is provided with air inlet pipe, and air inlet pipe and mould joint are provided with sealing ring.
