Mold for blowing and ejecting SNS rubber products for injection molding
Technical Field
The utility model relates to a SNS of car NVH product rubber production field of moulding plastics especially relates to a mould of ejecting SNS rubber product of moulding plastics of blowing.
Background
After injection molding of some SNS rubber injection molding products with complex shapes, when the SNS rubber injection molding products are ejected through machinery, the products are often damaged by ejection due to overlarge demolding force, or ejection difficulty or scratches are caused by too small ejection angles and product molding surfaces. Through this patent design, this problem has effectively been solved. The method can solve the problem of difficult ejection caused by too small ejection angle, and increase the forming process window of the product.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a mould of ejecting SNS rubber product of moulding plastics of blowing.
The utility model discloses a realize through following technical scheme:
the utility model provides a mould of ejecting SNS rubber product of moulding plastics of blowing, includes the mould core, the surface of mould core is equipped with the product profile, two gas passage have been seted up to mould core inside, and gas passage link up the mould core downwards, set up two standing grooves that communicate with gas passage respectively on the mould core, the standing groove is fixed with the pneumatic valve, set up three thimble hole that link up from top to bottom on the mould core.
Furthermore, the mould core is convex, one of the thimble holes is located at the central line of the mould core, and the other two thimble holes are distributed at two sides of the thimble hole located at the central line.
The utility model has the advantages that:
the scheme is different from the existing ejector pin ejection, the SNS rubber product is used and injected, and the scheme is also suitable for the molding of other soft injection molding materials, so that the applicability and the processing convenience of the product can be increased, and the non-contact ejection of the injection molding rubber product can be realized by the gas ejection SNS rubber injection molding product, so that the appearance performance of the product is improved, and the design structure of a mold is simplified. Can also be according to changing different ejecting positions, inclination and size, can produce the SNS rubber injection moulding product that corresponds different shapes, through this patent design, effectively solved because the problem of mechanical ejection damage product.
Drawings

in the figure: 1. a mold core; 2. a gas channel; 3. a placement groove; 4. an air valve; 5. a thimble hole.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a mould core 1, the surface of mould core 1 is equipped with the product shaping face, 1 inside two gas passage 2 of having seted up of mould core, gas passage 2 link up mould core 1 downwards, set up two standing grooves 3 that communicate with gas passage 2 respectively on the mould core 1, standing groove 3 is fixed with pneumatic valve 4, set up three thimble hole 5 that link up from top to bottom on the mould core 1. The mould core 1 is in a convex shape, one thimble hole 5 is located at the central line of the mould core 1, and the other two thimble holes 5 are distributed at two sides of the thimble hole 5 located at the central line. Therefore, when the mold needs to be ejected, the mold is an SNS rubber product and has certain softness, the air valves 4 are inflated through the two air channels 2, the two sides of the mold formed on the mold core 1 are ejected through the air of the air valves 4, and the whole product is ejected integrally from bottom to top through the mechanical ejector pins in the three ejector pin holes 5, so that the demolding is completed.
The utility model has the advantages that:
this scheme is distinguished from present thimble ejecting, and the gas through pneumatic valve 4 is ejecting with the both sides that the product is difficult to the drawing of patterns because softer, does not need traditional machinery ejecting, can not harm the product, also is applicable to the shaping of other soft materials of moulding plastics simultaneously, can increase the suitability and the processing convenience of product, and the non-contact ejecting that the rubber product of moulding plastics can be realized to gas top SNS rubber injection moulding product to improve the appearance performance of product, simplify mould design structure. Can also be according to changing different ejecting positions, inclination and size, can produce the SNS rubber injection moulding product that corresponds different shapes, through this patent design, effectively solved because the problem of mechanical ejection damage product.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
