Abstract
The utility model discloses an upper die jaw micro-adjustment structure of a die head device, which comprises an upper die and a micro-adjustment device, wherein the micro-adjustment device comprises a micro-adjustment bolt and a micro-adjustment screw; both ends of the micro-adjustment bolt are provided with screw threads, and the screw pitches of inner and outer screw threads of the micro-adjustment screw are different, wherein the outer screw pitch is larger than the inner screw pitch. The adjustment structure uses the bolt with two different screw pitches to be matched with the screw to realize fine adjustment, so that the thickness of produced products is uniform.
Description
Technical field
The utility model relates to a kind of last die lip fine tuning structure of die head device, especially die head device of the extrusion moulding equipment that is used to produce plastic plate, film.
Background technology
Used production plastic plate, film extruding production line is made up of extruder and composite membrane head former now, and different materials is combined, and every layer thickness is set as requested.The die head of composite membrane head comprises upper die and lower die, and behind the upper and lower mould matched moulds, its die lip mouth leaves the gap of discharging.The set fine tuning structure of die lip on the above-mentioned die head, the set screw spacing is big, can not realize fine setting among a small circle, makes the in uneven thickness of extruded product.
The utility model content
The purpose of this utility model is to provide a kind of last die lip fine tuning structure that is used for die head device, overcomes above-mentioned defective, makes the openings of sizes of die lip can be among a small circle, the accurate adjustment.
For achieving the above object, the utility model provides following technical scheme:
The fine tuning structure of die lip on a kind of die head device comprises patrix and micromatic setting; Micromatic setting comprises trimming bolt and fine adjustment screw; The two ends of trimming bolt are provided with screw thread, and the pitch of fine adjustment screw internal and external threads is inequality, and its outer pitch is greater than interior pitch; The micromatic setting grouping is arranged on the upper die body; The top of last die lip is provided with trimming groove, and trimming bolt passes trimming groove, and its lower end is threaded and goes up the upper surface of die lip, and its upper end is connected with fine adjustment screw.
Above-mentioned trimming bolt is fixed on the upper die body by caging bolt.
Above-mentioned last die lip fine tuning structure has solved the adjusting problem of last die lip openings of sizes.This adjustment structure adopts the bolt of two different pitch and the cooperation of screw, can realize trickleer adjusting, makes that the product thickness of producing is even.
Description of drawings
Fig. 1 is a profile of the present utility model;
Fig. 2 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 3 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of die head comprises patrix 1 and counterdie 2, is connected and fixed by fixed screw 3.Behind patrix 1 and counterdie 2 matched moulds, its die lip mouth place leaves the gap of discharging.The last die lip fine tuning structure that above-mentioned patrix 1 has adopted the utility model to provide, the top of last die lip 11 is provided with trimming groove 12; Micromatic setting comprises trimming bolt 4 and fine adjustment screw 5.The two ends of trimming bolt 4 are provided with screw thread, and the pitch of fine adjustment screw 5 internal and external threads is inequality, and its outer pitch is greater than interior pitch; The micromatic setting grouping is arranged on the patrix 1; Trimming bolt 4 passes trimming groove 12, and its lower end is threaded and goes up the upper surface of die lip 11, and its upper end is connected with fine adjustment screw 5, and trimming bolt 4 is fixed on the upper die body 1 by caging bolt 14.
During adjusting, rotary fine adjustment screw 5, because the inside and outside pitch of fine adjustment screw 5 is inequality, outer pitch is greater than interior pitch, the bolt and the screw of two different pitch match, and can realize trickleer, accurate adjusting.When screwing, die lip 11 on the trimming bolt 4 downward roof pressures makes its openings get smaller; When unscrewing, trimming bolt makes it micro-deformation by die lip in the pull-up that is threaded, and it is big that opening becomes.The novel last die lip fine tuning structure that provides of this use is produced patrix in the die head device of extrusion moulding equipment of plastic plates, film applicable to all.
