Abstract
The utility model discloses a core-pulling structure used for injection molding of an arc-shaped product. The core-pulling structure comprises a product seat and a hydro-cylinder, and the hydro-cylinder is connected with a linear core of the product through a connecting block; an arc rail is arranged in the product seat, a slide block is arranged in the arc rail and connected with a arc-shaped mold core; the slide block is connected with a steering block which is connected with a buffering block arranged on the connecting block through a connecting rod. Compared with an existing mould, the core-pulling structure used for the injection molding of the arc-shaped product is simple in structure and reasonable in design, by means of an arc movement, the arc-shaped mold core is pulled out, the performance is stable and reliable, and the core-pulling structure ensures that produced injection molding parts are stable in quality and fully meet technical requirements of products, has good practical applicability, and can create good economic benefit and social effects.
Description
Technical field
The utility model relates to blow mold, is specifically related to a kind of pulled core structure for injection moulding circular shape product.
Background technology
At present, when the product with mold injection is when the product of side opening is arranged, can adopt slide block or oil cylinder to loose core, but slide block and oil cylinder can only be finished the straight line of product and loose core, can not have the product of certain radian to loose core, if adopt slide block and loose core of oil cylinder will pull open product, generation is scrapped.And existing circular shape product often adopts the gear drive demoulding, but when adopting the gear demoulding, structure is very complicated, and difficulty of processing is high, and the manufacturing cycle is long, and relative cost is very high, can not satisfy user demand fully.
The utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model provides a kind of pulled core structure for injection moulding circular shape product, adopts connecting rod core loosening mechanism, and the circular shape product is efficiently loosed core, reduce production costs, improve the yield rate of product.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of pulled core structure for injection moulding circular shape product comprises product seat and oil cylinder, and described oil cylinder links to each other with the straight line core of product by contiguous block; In described product seat, be provided with arc track, in arc track, be provided with slide block and link to each other with the circular arc core; Described slide block links to each other with steering block, and described steering block links to each other with buffer stopper on being located at contiguous block by connecting rod.
The product of described circular shape product for using simultaneously straight line core and circular arc core to carry out injection moulding.
The radian of described arc track is identical with the radian of circular shape product.
The mould that contains pulled core structure of the present utility model, when the mould die sinking, under the effect of curved pin, the circular arc core is mobile backward, break away from packing tightly of plastic product, the mould die sinking is behind certain distance, and the oil cylinder front end will oil-feed, and oil cylinder continues drivening rod under the effect of pressurized mobile backward, connecting rod drives the circular arc core simultaneously, can under the effect of connecting rod and circular arc guide runner, produce circular motion, finish arc core-pulling.During matched moulds, the air inlet of oil cylinder rear end promotes connecting rod, circular arc core etc. and moves forward, move to a segment distance after, the mould die sinking, curved pin will compress the circular arc core, prevents that the circular arc core is mobile backward, plays wedge action.
Beneficial effect: compare with existing mould, pulled core structure for injection moulding circular shape product of the present utility model, simple in structure, reasonable in design, adopt circular motion to extract the circular arc core out, stable and reliable for performance, guarantee that the plastic part quality of producing is stable, meet the specification requirement of product fully, have fine practicality, can produce good economic benefit and social effect.
Description of drawings
Fig. 1 is the structural representation of pulled core structure;
Fig. 2 is the connection diagram of pulled core structure;
Fig. 3 is the work schematic diagram of pulled core structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As shown in Figure 1, the pulled core structure for injection moulding circular shape product mainly is comprised of parts such as contiguous block 2, oil cylinder 3, buffer stopper 4, connecting rod 5, steering block 11, slide block 6 and arc tracks 7.Buffer stopper 4, connecting rod 5, steering block 11 and slide block 6 link to each other successively, form linkage.Buffer stopper 4 is located on the contiguous block 2, and contiguous block 2 links to each other with oil cylinder 3, and is driven by oil cylinder 3.Slide block 6 links to each other with circular arc core 10 in being located at product 8.Slide block 6 is located in the arc track 7, and along the orbiting motion of arc track 7, the radian of arc track 7 is identical with the radian of product 8, so just can guarantee that circular arc core 10 can not draw bad product 8 in the process of extracting out.
Pulled core structure for injection moulding circular shape product of the present utility model, simple in structure, reasonable in design, adopt circular motion to extract the circular arc core out, stable and reliable for performance, guarantee that the plastic part quality of producing is stable, meet the specification requirement of product fully, have fine practicality, can produce good economic benefit and social effect.
