The angular core-pulling mechanism comprises a big slide block; one end of the big slide block is in contact with products; an oil cylinder is connected to one side of the big slide block; hydraulic oil is injected into the oil cylinder; a small slide block is arranged at the upper part of the big slide block; and one end of the small slide block is in contact with the products. The angular core-pulling mechanism has the advantages of simple structure, easy control, stable operation, low maintenance cost, and requirement compliance.

Description

The angle core-pulling mechanism that is used for mould
Technical field
The utility model is a kind of angle core-pulling mechanism, particularly a kind of angle core-pulling mechanism that is used for mould.
Background technology
In the prior art, along with the development of technology, what the structure of plastic member product also became becomes increasingly complex, and a plurality of different angles of loosing core may occur in the same zone of loosing core, and simply slide block can only guarantee that a direction slide block loosed core in the past, can't satisfy the demands.
Chinese patent CN201268070, a kind of injection mold with cover half angle core-pulling mechanism is disclosed, comprise solid plate, the cover half cavity plate, dynamic mould core and cover half angle core-pulling mechanism, it is characterized in that described cover half angle core-pulling mechanism comprises mouth of a river plate, the spring of loosing core, spring guide pillar, big slide block, middle slide block, small slide block, positioning ball, spring guide pillar is provided with round cap, the cover half cavity plate is provided with positioning step, spring guide pillar and cover half cavity plate are slidingly connected, the both ends of the spring of loosing core connects mouth of a river plate and cover half cavity plate, big slide block be slidingly connected with middle slide block, middle slide block and small slide block are slidingly connected.This utility model patent structure relative complex, and be not very smooth, wayward during die sinking.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of angle core-pulling mechanism that is used for mould that is plugged with small slide block in big slide block is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of angle core-pulling mechanism that is used for mould comprises big slide block, and an end of big slide block contacts with product, and a side of big slide block is connected with oil cylinder, is provided with hydraulic oil in the oil cylinder, and the top of big slide block is provided with small slide block, and an end of small slide block contacts with product.Big slide block contacts with large-area product, and small slide block accounts for the fraction area, and small slide block is plugged in the big slide block, and the two exists simultaneously, mutually noninterfere, and big slide block is driven by hydraulic jack, and small slide block provides mechanical system to drive by sliding block spring; During die sinking, oil cylinder is motionless, keeps big slide block transfixion, and the assurance small slide block is preferentially finished oblique loosing core, and drives big slide block by oil cylinder again and looses core; During matched moulds, preferentially resetted by big slide block, again by the dynamic model matched moulds, it is oblique compound to finish small slide block by mould assembling action.During die sinking,, can not skid off simultaneously because big slide block skids off the different of direction with small slide block, otherwise mechanism directly interferes, and big slide block skids off earlier and can the little slip of drive skid off, because small slide block skids off earlier, Deng small slide block slide into break away from product after, skid off also by big slide block direction again and can not fastened by product.Small slide block generally is positioned at the middle part or the top of big slide block.
As preferably, be provided with the small slide block spring between described small slide block and the big slide block, the other end of small slide block is provided with the Angle Pin hole, and Angle Pin is plugged with Angle Pin in the hole, and a side of Angle Pin is fixed with the slide block voussoir, and described small slide block is oblique with big slide block and establishes.
As preferably, described small slide block is plugged in the big slide block, Angle Pin and being integral of slide block voussoir, Angle Pin and the clamping mutually of Angle Pin hole; The glide direction that skids off direction and big slide block of small slide block is 0 °~20 °.Angle is in this scope, and the risk of small slide block action is smaller.
As preferably, the bottom of described big slide block is provided with the bottom wearing plate, and the back of big slide block is provided with the back wearing plate.The bottom wearing plate is positioned at the bottom of big slide block, plays the wear-resisting anti-interlocking of fine setting effect of slide block upper-lower position and slide block, also is provided with chute on the wearing plate, plays the effect of slip store oil and appearance foreign matter.
Therefore, the utility model is provided for the angle core-pulling mechanism of mould, and is simple in structure, control easily, and stable, maintenance cost is low, is fit to demand.
Description of drawings
Fig. 1 is the matched moulds structural representation of analysing and observe of the present utility model;
Fig. 2 is the die sinking structural representation of analysing and observe of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as depicted in figs. 1 and 2, a kind of angle core-pulling mechanism that is used for mould, comprise big slide block 1, one end of big slide block 1 contacts with product 2, one side of big slide block 1 is connected with oil cylinder 3, be provided with hydraulic oil 4 in the oil cylinder 3, the top of big slide block 1 is provided with small slide block 5, one end of small slide block 5 contacts with product 2, be provided with small slide block spring 6 between small slide block 5 and the big slide block 1, the other end of small slide block 5 is provided with Angle Pin hole 7, be plugged with Angle Pin 8 in the Angle Pin hole 7, a side of Angle Pin 8 is fixed with slide block voussoir 9, and described small slide block 5 is oblique with big slide block 1 and establishes, small slide block 5 is plugged in the big slide block 1, Angle Pin 8 and slide block voussoir 9 being integral, Angle Pin 8 and Angle Pin hole 7 clamping mutually, the glide direction that skids off direction and big slide block 1 of small slide block 5 is 0 °~20 °, the bottom of big slide block 1 is provided with bottom wearing plate 10, and the back of big slide block 1 is provided with back wearing plate 11.
Operation principle: during work, can look big slide block and small slide block is same system.The slip system of loosing core, under the effect of oil cylinder, big slide block and small slide block are pushed ahead, and arrive stroke and do not hold, and make small slide block and big slide block all arrive the assigned work position.Be fixed on the Angle Pin on the slide block voussoir, along with moving down of slide block voussoir, the Angle Pin hole that enters into small slide block of success, stirring small slide block looses core and moves to the impulse stroke terminal, compression simultaneously is positioned at the spring of slip front end, makes it to compress the small slide block spring that is positioned at the slip front end, produces elastic potential energy, for retreating of later stage small slide block, provide power.
During die sinking, the slide block voussoir rises, big slide block oil cylinder keeps motionless, looking small slide block fully is a driving mechanism, along with the continuation of slide block voussoir is risen, is fixed on slide block and carves the Angle Pin of piece and stir backward, and under the effect of small slide block spring, small slide block is retreated to start of a run, and oil cylinder drives big the slip and retreats, and makes it to arrive big ram travel starting point.
When product was in no back-off state, product was ejected fully.
