Abstract
The utility model discloses a self -adaptation formula sealing device for stock mould, it includes assembles the groove, the assembly inslot lays sealing strip (1) that the external diameter is less than assembly inslot footpath, the locating hole has been seted up to assembly groove lateral wall, screw -thread fit has screw (3) in the locating hole, the adaptation has flexible clamp plate (2) between thread end and the sealing strip. The beneficial effects of the utility model are that can make and open or the obvious shortcoming that weakens current fastening mode of closed process in the plastic extrusion production process, extension joint strip's life reaches the saving cost, reduces secondary clamping risk, and then plays the effect that environmental protection and save material and manpower were worked.
Description
Technical field
The utility model relates to sealing device, relates in particular to the sealing device for stock mould.
Background technology
Plastic extruding forming tends to repeatedly closure or openness sealing strip in producing to observe section bar state. In existing plastic extruding forming production process, the repeatedly unlatching closing course of sealing strip can cause sealing strip fracture due to existing fastener shortcoming. Main cause is, existing fastening means is by the direct fit sealing bar of screw, due to screw bottom faces rib there is cutting edge the thorn-like band that occurs due to processing problems is stretching to sealing strip and trip bolt contact portion artificially in opening encapsulation bar process or subsidiary rotary course in produce shearing or sawing effect, along with the time increases, contact portion unstable wear or fracture, cause sealing strip fracture to lose sealing effectiveness.
Utility model content
The technical problems to be solved in the utility model is that existing sealing strip is easily ruptured by screw effect, and service life is short, and a kind of self-adapting type sealing device for stock mould is provided for this reason.
The technical solution of the utility model is: for the self-adapting type sealing device of stock mould, it comprises fitting recess, in described fitting recess, be laid with the sealing strip that external diameter is less than fitting recess internal diameter, described fitting recess sidewall offers locating hole, described locating hole screw-internal thread fit has screw, and between described tip of screw and sealing strip, adaptation has flexible pressing plate.
The improvement of such scheme is to be filled with steel ball between described flexible pressing plate and sealing strip laminating.
The beneficial effects of the utility model are the shortcomings that can make obviously to weaken in opening and closing of fault process in plastic extrusion production process existing fastening means; extend the service life of sealing joint strip; reach cost-saving; reduce secondary clamping risk, and then play protection of the environment and save material and the effect of manpower work.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram;
In figure, 1, sealing strip, 2, flexible pressing plate, 3, screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises fitting recess, is laid with the sealing strip 1 that external diameter is less than fitting recess internal diameter in described fitting recess, and described fitting recess sidewall offers locating hole, described locating hole screw-internal thread fit has screw 3, and between described tip of screw and sealing strip, adaptation has flexible pressing plate 2.
When assembling, first sealing strip is put into fitting recess, because sealing strip external diameter is less than the internal diameter of fitting recess, so now sealing strip is in relaxed state, flexible pressing plate is put into fitting recess and block locating hole, again screw is inserted to locating hole from outside, the oppressed crush seal bar of flexible pressing plate in the process that screw tightens, thus the sealing of sealing strip completed. Due to the accreditation morphotropism of flexible pressing plate, can produce deformation in pressurized process and abut in sealing strip surface, sealing strip is played to certain protective role, while preventing upper and lower screw, sealing strip is by screw breakage.
In order further to strengthen the dependability of sealing strip, can between flexible pressing plate and sealing strip laminating, be filled with steel ball, making to change sliding friction between flexible pressing plate and sealing strip is rolling friction, reduces the frictional force that sealing strip is subject to, and extends the service life of sealing strip.
For fear of producing friction between sealing strip and the notch of fitting recess, be preferably arc transition by the notch design of fitting recess.
Claims (2)
1. for the self-adapting type sealing device of stock mould, it is characterized in that it comprises fitting recess, in described fitting recess, be laid with the sealing strip (1) that external diameter is less than fitting recess internal diameter, described fitting recess sidewall offers locating hole, described locating hole screw-internal thread fit has screw (3), and between described tip of screw and sealing strip, adaptation has flexible pressing plate (2).
2. the self-adapting type sealing device for stock mould as claimed in claim 1, is characterized in that being filled with steel ball between described flexible pressing plate and sealing strip laminating.
