Abstract
The invention discloses a core pulling structure for an injection-molded arc product, which comprises a product seat and an oil cylinder, wherein the oil cylinder is connected with a straight core of the product by a connection block; an arc railway is arranged in the product seat and internally provided with a slide block to connect an arc core; and the slide block is connected with a steering block which is connected with a buffering block on the connection block by a connecting rod. Compared with the existing mould, the core pulling structure for the injection-molded arc product is simple in structure and reasonable in design, the arc core is pulled out by the arc action, the performances are stable and reliable, the quality of a produced plastic piece is enabled to be stable, the technical requirements on the product can be completely met, quite good practicality is achieved, and excellent economic and social benefits are brought.
Description
Technical field
The present invention relates to blow mold, be specifically related to a kind of structure of loosing core that is used for injection moulding circular shape product.
Background technology
At present, when the product that uses 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 accomplished 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.
Summary of the invention
Goal of the invention: to the deficiency that exists in the prior art; The purpose of this invention is to provide a kind of structure of loosing core that is used for injection moulding circular shape product, adopt the connecting rod core-pulling mechanism, 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 scheme that the present invention adopts is:
A kind of structure of loosing core that is used 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 through 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 through connecting rod.
The product of described circular shape product for using straight line core and circular arc core to carry out injection moulding simultaneously.
The radian of described arc track is identical with the radian of circular shape product.
The mould that contains the structure of loosing core of the present invention is when the mould die sinking, under the effect of curved pin; The circular arc core moves backward, breaks away from packing tightly of plastic product, and the mould die sinking is behind certain distance; The oil cylinder front end will oil-feed, and oil cylinder continues drivening rod and moves backward under the effect of pressurized, and connecting rod drives the circular arc core simultaneously; Can under the effect of connecting rod and circular arc guide runner, produce circular motion, accomplish 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 from moving backward, plays wedge action.
Beneficial effect: compare with existing mould, the structure of loosing core that is used for injection moulding circular shape product of the present invention, 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 benefits and social effect.
Description of drawings
Fig. 1 is the structural representation of structure of loosing core;
Fig. 2 is the connection sketch map of structure of loosing core;
Fig. 3 is the work sketch map of structure of loosing core.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1, the structure of loosing core that is used for injection moulding circular shape product mainly is made up 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 cores 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.
The structure of loosing core that is used for injection moulding circular shape product of the present invention, 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 benefits and social effect.
