Abstract
The utility model discloses a thickness adjusting device of a PS (Poly Styrene) foam sheet extrusion die. The thickness adjusting device comprises a die body, an inner die lip and an outer die lip, and also comprises a flow insert, wherein a flow adjusting ring is arranged in the die body; a plurality of notches are formed in the flow adjusting ring; a flow adjusting block is correspondingly arranged in each notch; a flow adjusting bolt is eccentrically arranged on the flow adjusting block; and the flow insert is arranged in the die body and forms a runner together with the flow adjusting ring and the flow adjusting blocks. The thickness adjusting device of the PS foam sheet extrusion die is capable of conveniently adjusting the local thickness of the extruded foam sheet, and does not cause deformation of the parts during adjustment.
Description
Technical field:
The utility model relates to a kind of adjusting device, specifically is a kind of thickness adjusting device of PS foam sheet extrusion neck ring mold.
Background technology:
At present, most of PS(polystyrene) the foam sheet extruder, the thickness adjustment of its extrusion sheet all is to realize by the local gap that changes between interior die lip, outer die lip.Concrete structure is seen Fig. 1.Be evenly equipped with 12 screws on the outer ring circumference of die lip outside, debug the joint swivel nut in the screw.Also uniform 12 screws on the inner ring relevant position of die lip are outside regulated bolt and are passed Adjusting bolt Adjusting screw and link to each other with the inner ring screw.When there is the phenomenon of became uneven the sheet material part of extruding, by rotating Adjusting bolt Adjusting screw, can make the inner ring of outer die lip produce small strain, make the gap of outer die lip and interior die lip corresponding position change, thereby the thickness of extrusion sheet is adjusted.The mode major defect of this adjusting thickness is: need make outer die lip inner ring produce strain, metal produces strain needs bigger external force, relatively requires great effort when therefore adjusting.In addition, after often adjusting, outer die lip reaches fatigue limit, and inner ring ruptures easily, and the service life of mouthful mould is not long.
The utility model content:
Technical problem to be solved in the utility model is, a kind of thickness adjusting device of PS foam sheet extrusion neck ring mold is provided, movement by traffic conditioner block in the mouth mould changes the gap in the runner, thereby adjust the local thickness of the foam sheet extrude, this easy to adjust laborsaving and can not cause part deformation.
Technical solution of the present utility model is, a kind of thickness adjusting device of PS foam sheet extrusion neck ring mold is provided, comprise die body, interior die lip and outer die lip, comprise that also flow inserts, be provided with the Flow-rate adjustment ring in the described die body, described Flow-rate adjustment ring is provided with a plurality of notches, correspondence is provided with traffic conditioner block in each notch, off-centre is provided with the Flow-rate adjustment bolt on the traffic conditioner block, and described flow is inserted and is located in the die body, and forms runner with Flow-rate adjustment ring and traffic conditioner block.
Adopt after the above structure compared with prior art, the utlity model has following advantage: flow is inserted and is formed runner with Flow-rate adjustment ring and traffic conditioner block, when there is the thickness deviation in the foam sheet part of extruding, the Flow-rate adjustment bolt of rotation relevant position, the drive traffic conditioner block moves forward and backward, make the gap in the runner change, the foam sheet thickness of extruding obtains adjusting, this regulative mode is the interior traffic conditioner block of mobile runner only, do not need very big strength, easy to operate.And can not cause the distortion of each correlated parts, service life is longer.
As preferably, the circumferential wall of described notch longshore current amount adjustable ring is evenly spaced apart.It is more reasonable to arrange.
As preferably, described notch has 16.Such setting is more reasonable.
Further, also comprise clamping screw, described clamping screw cooperates with the Flow-rate adjustment bolt.Can prevent that like this Flow-rate adjustment bolt from rotating.
Description of drawings:
Fig. 1 is the structural representation of thickness adjusting device of the PS foam sheet extrusion neck ring mold of prior art.
Fig. 2 is structural representation of the present utility model.
Among the figure, 1, die body, 2, interior die lip, 3, outer die lip, 6, foam sheet, 7, the Flow-rate adjustment ring, 8, traffic conditioner block, 9, the Flow-rate adjustment bolt, 10, runner inserts 11 clamping screws.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 2, a kind of thickness adjusting device of PS foam sheet extrusion neck ring mold, comprise die body 1, interior die lip 2 and outer die lip 3, comprise that also flow inserts 10, be provided with Flow-rate adjustment ring 7 in the described die body 1, described Flow-rate adjustment ring 7 is provided with 16 notches, the circumferential wall of described notch longshore current amount adjustable ring 7 is evenly spaced apart, correspondence is provided with traffic conditioner block 8 in each notch, off-centre is provided with Flow-rate adjustment bolt 9 on the traffic conditioner block 8, and specifically, the part in the Flow-rate adjustment bolt 9 insertion traffic conditioner blocks 8 has certain skew with the center of traffic conditioner block 8, when Flow-rate adjustment bolt 9 rotates, traffic conditioner block 8 is moved forward and backward in Flow-rate adjustment ring 7; Also comprise clamping screw 11, described clamping screw 11 cooperates with Flow-rate adjustment bolt 9, and described flow is inserted and 10 is located in the die body 1, and forms runners with Flow-rate adjustment ring 7 and traffic conditioner block 8.
When there is the thickness deviation in foam sheet 6 parts of extruding, the Flow-rate adjustment bolt 9 of rotation relevant position, driving traffic conditioner block 8 moves forward and backward, make the gap in the runner change, foam sheet 6 thickness of extruding obtain adjusting, adjust back rotational lock bolt 11, prevent that Flow-rate adjustment bolt 9 from rotating.This regulative mode is the interior traffic conditioner block 8 of mobile runner only, does not need very big strength, and is easy to operate.And can not cause the distortion of each correlated parts, service life is longer.
Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do includes within scope of patent protection of the present utility model.
