Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
An automobile rubber pipe extrusion die is used for an automobile rubber pipe and comprises an inner section 1, an outer section 2, a plurality of layers of gasket groups 3, a plug 4 and an outer sleeve 5, as shown in figures 1 to 4.
The inner section 1 is columnar, the outer section 2 is conical, the outer section 2 is connected with the inner section 1, the outer section 2 and the inner section 1 are provided with communicated channels, and the channels can be used for cooling the inner side of the rubber pipe and reducing the weight.
The surface of the outer section 2 is provided with a plurality of mounting grooves which are arranged in a certain shape. Several layers of gasket groups 3 are arranged in the outer side of the outer section 2 in sequence, each layer of gasket group 3 comprises at least two gaskets, the reference figure 3 is combined, the inner sides of the gaskets are provided with mounting columns, the outer sides of the gaskets are provided with mounting grooves, and the mounting columns are arranged in the mounting grooves.
For example, the extrusion die shown in fig. 1 has two layers of gasket sets 3, the two layers of gasket sets 3 are sequentially installed on the outer side of the outer section 2, each layer of gasket set 3 is composed of four gaskets, and during installation, one gasket in each group is installed, that is, the installation column is placed in the installation groove. Because the junction of the inner section 1 and the outer section 2 is conical, and the gasket group 3 is mounted on the outer section 2, the junction of each layer of gasket group 3 and the inner section 1 is internally conical. In this case, the joint between the gasket group and the inner section 1 can be smoothly transited.
This application extrusion die's outer section 2 is the variable diameter, and the reducing mainly embodies at what of shim group 3, and the event increases the one deck each time, then the thickness of rubber tube just reduces a bit, and at this moment, if not mounting shim group 3 in the mounting groove of outer section 2, then set up stopper 4 in the mounting groove of outer section 2, the top of stopper 4 matches with the cambered surface of outer section 2, and pipeline strutting arrangement's external diameter is minimum this moment. When needs increase external diameter, install one deck gasket group 3 on outer section 2, that is to say extract above-mentioned stopper 4, then install the gasket in the mounting groove of gasket, install stopper 4 on outermost gasket group 3 next, this time, the top of stopper 4 matches with the cambered surface of gasket to accomplish above-mentioned operation, so this application stopper 4's shape and size is different. The plug 4 prevents glue from accumulating in the mounting groove.
For better installation and removal of the plug 4, the plug 4 is designed, and the top end of the plug 4 is provided with a hook groove, and 3D printing can be adopted during processing, or the plug is divided into two halves at the hook groove and welded together. When the plug 4 is used, the hook groove of the plug can be blocked, the blocking does not influence the use of the plug, and the disposable plug 4 can be used or related medicaments are adopted to assist in taking out part of rubber in the hook groove so as to take out the plug 4.
The outer sleeve 5 is arranged on the outer sides of the columnar inner section 1 and the gasket group 3 and forms a cavity which is communicated with the rubber material and used for receiving the rubber material and extruding the rubber material.
When the extrusion die is used, at least the following three methods are adopted,
one is as follows: selecting a proper rubber pipe thickness according to requirements, and directly installing the plug 4 in the installation groove of the outer section 2 if the gasket group 3 is not needed;
the second step is as follows: if at least one shim pack 3 is required, the following method is used:
A. a plurality of layers of gasket groups 3 are arranged on the conical outer section 2;
B. the plug 4 is arranged in the mounting groove of the outer section 2;
C. the inner section 1 and the outer section 2 are mounted in a jacket 5.
Thirdly, if the thickness of the rubber tube is adjusted based on the second method, the following method is adopted based on the second method:
D. taking out the cylindrical inner section 1 and the conical outer section 2 from the outer sleeve 5;
E. taking out the plug from the mounting groove of the outer section 2;
F. continuously installing a certain number of gasket groups 3 on the outer sides of the gasket groups 3;
G. the plug 4 is arranged in the mounting groove of the outer section 2;
H. the cylindrical inner section 1 and the conical outer section 2 are mounted in an outer sleeve 5.
It should be understood that the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as no structural conflict exists; and all such modifications and alterations are intended to fall within the scope of the appended claims.
