Abstract
A protective device for the co-extrusion mouth of co-extrusion plate, comprises co-extrusion preformed board and protective sleeve.The utility model have employed and arranges protective sleeve at co-extrusion mouth; doing so avoids shape co-extrusion mouth being processed into screw thread; thus avoid destruction screw thread; adopt the structure of protective sleeve co-extrusion mouth can be processed into smooth circular hole; it also avoid the error caused due to tapping in process in co-extrusion preformed board like this makes co-extrusion preformed board processing error will lose very large; and adopt the mode of protective sleeve; just can avoid this problem, only need to change protective sleeve because if go wrong.
Description
Technical field
The utility model relates to a kind of co-extruding mould device, especially relates to a kind of protective device of co-extrusion mouth of co-extrusion plate.
Background technology
A set of color coextrusion mould needs on co-extrusion preformed board, process co-extrusion connecting thread and coextrusion connects and could normally produce with it, actual is that co-extrusion connecting thread mounts and dismounts in the middle of process client and easily breaks silk, cause this template can not normal production and application, the duration is produced in impact, too increases die cost simultaneously.
Utility model content
The purpose of this utility model is the problem that the connecting thread for solving original template co-extrusion mouth is easily destroyed, and provides a kind of protective device of co-extrusion mouth of co-extrusion plate.
The utility model is the deficiency solved the problems of the technologies described above, and the technical scheme adopted is:
A kind of protective device of co-extrusion mouth of co-extrusion plate, comprise co-extrusion preformed board and protective sleeve, protective sleeve comprises contiguous block and cylindrical boss, cylindrical boss is arranged on one end of contiguous block and the centre of gyration line of cylindrical boss overlaps with the center line of contiguous block, the other end of contiguous block offers screwed hole, the center line of screwed hole overlaps with the centre of gyration line of cylindrical boss, cylindrical boss offers the circular hole along its axis, circular hole is communicated with screwed hole, contiguous block is positioned at the monosymmetric of screwed hole and is provided with a pair installing hole, the co-extrusion mouth of co-extrusion preformed board is set to smooth circular hole, the cylindrical boss of protective sleeve is plugged in smooth circular hole and is also fixed in co-extrusion preformed board by protective sleeve by the screw through installing hole.
The beneficial effects of the utility model are: the utility model have employed and arranges protective sleeve at co-extrusion mouth; doing so avoids shape co-extrusion mouth being processed into screw thread; thus avoid destruction screw thread; adopt the structure of protective sleeve co-extrusion mouth can be processed into smooth circular hole; it also avoid the error caused due to tapping in process in co-extrusion preformed board like this makes co-extrusion preformed board processing error will lose very large; and adopt the mode of protective sleeve; just can avoid this problem, only need to change protective sleeve because if go wrong.

Detailed description of the invention
Shown in figure, detailed description of the invention is as follows:
A kind of protective device of co-extrusion mouth of co-extrusion plate, comprise co-extrusion preformed board 7 and protective sleeve 6, protective sleeve 6 comprises contiguous block 602 and cylindrical boss 603, cylindrical boss 603 is arranged on one end of contiguous block 602 and the centre of gyration line of cylindrical boss 603 overlaps with the center line of contiguous block 602, the other end of contiguous block 602 offers screwed hole 604, the center line of screwed hole 604 overlaps with the centre of gyration line of cylindrical boss 603, cylindrical boss 603 offers the circular hole 605 along its axis, circular hole 605 is communicated with screwed hole 604, contiguous block 602 is positioned at the monosymmetric of screwed hole 604 and is provided with a pair installing hole 601, the co-extrusion mouth of co-extrusion preformed board 7 is set to smooth circular hole, the cylindrical boss 603 of protective sleeve 6 is plugged in smooth circular hole and is also fixed in co-extrusion preformed board 7 by protective sleeve 6 by the screw through installing hole 601.
Concrete mounting structure shown in figure is that co-extrusion machine flange (1) is connected with screw with mould flange (2); positioning sleeve (3) screws in mould flange (2); be connected with breathing out not block (4) pieces with co-extrusion connecting filament (5); co-extrusion connecting filament (5) is connected with protective sleeve (6), and protective sleeve (6) and co-extrusion preformed board (7) use fastened by screw.
Fig. 3: when not installing protective sleeve (6); co-extrusion connecting filament (5) and co-extrusion preformed board (7) are directly with when being threaded; can damage the screw thread of co-extrusion preformed board (7) in the middle of the process of dismounting; connection can not well screw in or screw in not on earth, causes faying face to have gap to produce and leaks material.Also having is exactly once co-extrusion preformed board screw thread has damaged, and is difficult to remedy! If large for screw thread processing, accessory has not just matched, and only has and co-extrusion preformed board is scrapped, and because of this template chamber and co-extruding flow channel complexity, and the side's of being template is also higher to the requirement of car screw thread, and processing technology requirement is high, the cycle is long, has a strong impact on client and produces.When adopting protective sleeve to connect, once there is the situation of the screw breaking protective sleeve in process of production, direct replaceable protective sleeve just; convenient and simple; protective sleeve can be designed to the shape of interchangeable nut simultaneously, thus can be used as standard component production in enormous quantities, and cost is also lower.
Technical scheme cited by the utility model and embodiment be not restriction, be equal to the technical scheme cited by the utility model and embodiment or effect same approach all in the scope that the utility model is protected.
