Abstract

The utility model discloses a kind of floating pin self-locking device for tunnel loose core mechanism, comprise device body, be provided with line position seat in described device body, this line position seat is provided with medium; The both sides of described medium are provided with the first floating pin and floatingly sell with second, and one end of medium is connected with driving mechanism; Described line position seat is fixedly connected with tunnel minute hand, and this tunnel minute hand is positioned at the one end away from driving mechanism.The utility model is used in first loosing core in compound movement and carries in the core-pulling mechanism of auto-lock function, pass through loose core of oil cylinder, inductor release signal controlled motion, makes the stable movement of whole mechanism avoid confusion in order, and self-locking device is simplified easy simultaneously, do not need traditional old-fashioned backhoe mechanism, save input cost energetically, simplify motion structure, and be connected rigorous between the parts of each routing motion, without Surplus Moment loss, there is lifting to a great extent to production efficiency.

Description

A kind of floating pin self-locking device for tunnel loose core mechanism
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of floating pin self-locking device for tunnel loose core mechanism.
Background technology
The tunnel loose core mechanism that increasing plastic makes plastic border have multiple mutual superposition staggered according to the requirement of serviceability and various erection technological requirement is had in daily life and industrial production.Be no lack of this bolt-type mechanism having long core-pulling mechanism simultaneously will pass multiple structure, the sequence of motion of this mechanism has strict demand, and because the effect of injection pressure can cause retreating in the injection moulding of batch is produced.This type of traditional bolt-type core-pulling mechanism easily occurs that sequence of motion is chaotic, draw other accessories of bad mould, penetrate pressure to retreat, damage the problem of plastic product, often select to newly increase the counteracting of a set of backhoe mechanism again in prior art and penetrate pressure, this just increases complexity and the sequence of motion control difficulty of mechanism more.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of floating pin self-locking device for tunnel loose core mechanism, being used in first loosing core in compound movement carries in the core-pulling mechanism of auto-lock function, pass through loose core of oil cylinder, inductor release signal controlled motion, the stable movement of whole mechanism is avoided confusion in order, self-locking device is simplified easy simultaneously, do not need traditional old-fashioned backhoe mechanism, save input cost energetically, simplify motion structure, and be connected rigorous between the parts of each routing motion, lose without Surplus Moment, lifting is to a great extent had to production efficiency.
To achieve these goals, the technical solution used in the present invention is such: a kind of floating pin self-locking device for tunnel loose core mechanism, and comprise device body, be provided with line position seat in described device body, this line position seat is provided with medium; The both sides of described medium are provided with the first floating pin and floatingly sell with second, and one end of medium is connected with driving mechanism; Described line position seat is fixedly connected with tunnel minute hand, and this tunnel minute hand is positioned at the one end away from driving mechanism.
As a kind of preferred version, described driving mechanism is oil cylinder.
As a kind of preferred version, described oil cylinder is by the first inductive pick-up and the second inductive pick-up transmission of signal controlled motion.
As a kind of preferred version, described tunnel minute hand is connected on line position seat by insert.
As a kind of preferred version, described line position seat is connected with device body by gag lever post.
As a kind of preferred version, the length of described gag lever post is less than the length of device body.
Compared with prior art, beneficial effect of the present invention: the present invention is used in first loosing core in compound movement and carries in the core-pulling mechanism of auto-lock function, pass through loose core of oil cylinder, inductor release signal controlled motion, the stable movement of whole mechanism is avoided confusion in order, self-locking device is simplified easy simultaneously, do not need traditional old-fashioned backhoe mechanism, save input cost energetically, simplify motion structure, and be connected rigorous between the parts of each routing motion, without Surplus Moment loss, there is lifting to a great extent to production efficiency.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the using state figure mono-in the embodiment of the present invention;
Fig. 3 is the using state figure bis-in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1, a kind of floating pin self-locking device for tunnel loose core mechanism, comprise device body 1, be provided with line position seat 2 in described device body 1, this line position seat 2 is provided with medium 3; The both sides of described medium 3 are provided with the first floating pin 4 and the second floating pin 5, and one end of medium 4 is connected with driving mechanism 7; Described line position seat 2 is fixedly connected with tunnel minute hand 8, and this tunnel minute hand 8 is positioned at the one end away from driving mechanism 7; Described driving mechanism 8 is oil cylinder; Described oil cylinder is by the first inductive pick-up 91 and the second inductive pick-up 92 transmission of signal controlled motion; Described tunnel minute hand 8 is connected on line position seat 2 by insert 10; Described line position seat 2 is connected with device body 1 by gag lever post 6; The length of described gag lever post 6 is less than the length of device body 1.During concrete enforcement, be a tunnel loose core mechanism as shown in Figure 2 and Figure 3, comprise the component such as front mold core A, rear mold core B, Slide mechanism C, Slide mechanism D, Slide mechanism E, after mold injection pressurize, before front and back mould is opened, want Xian Choukaici mechanism, then front and back mould, front mold core A, rear mold core B will be opened successively, then Slide mechanism C, Slide mechanism D, Slide mechanism E is exited, after ejecting pickup, Core mold slide first resets, mould matched moulds then, front mold core A, rear mold core B matched moulds, then reset.Wherein driving mechanism 7 is oil cylinder, provides signal controlled motion by the first inductive pick-up 91 and the second inductive pick-up 92.During complete matched moulds, the floating pin 5 of the first floating pin 4, second is strutted by medium 3, blocks line position seat 2, line position seat 2 can not be retreated because of injection pressure, guarantee normal injection moulding together.After injection moulding completes, before the mould die sinking of front and back, oil cylinder Received signal strength starts fuel feeding, and oil cylinder hauls medium 3 to start to shrink back, and in the process that medium 3 retreats, the floating pin 5 of the first floating pin 4, second is in softened state, so whole mechanism is also in matched moulds state always.When oil cylinder hauls after medium 3 moved back the floating pin 5 of the first floating pin 4, second, touch with line position seat 2, the floating pin 5 of the first floating pin 4, second will to inside contracting, and medium 3 drives line position seat 2 to draw back together, tunnel minute hand 8 is locked on line position seat 2 by insert 10, so just can extract tunnel out.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
