Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 5, the present invention includes: the heat flow channel plate assembly comprises a front heat flow channel plate 2, a rear heat flow channel plate 3, a left heat flow channel plate 4 and a right heat flow channel plate 5, wherein the front heat flow channel plate 2 and the rear heat flow channel plate 3 are mutually attached along one side of a nozzle and an internal flow channel, the left heat flow channel plate 4 and the right heat flow channel plate 5 are arranged at two ends of the front heat flow channel plate 2 and the rear heat flow channel plate 3, and a channel inside the left heat flow channel plate 4 and the right heat flow channel plate 5 is communicated with the internal flow channel of the front heat flow channel plate 2 and the internal flow channel of the rear heat flow channel plate 3 from front to back;
the joint of the left hot runner plate 4 and the front hot runner plate 2 as well as the joint of the rear hot runner plate 3 is sleeved with an annular fastening block 1;
and an annular fastening block 1 is sleeved outside the joint of the right hot runner plate 5 and the front hot runner plate 2 and the rear hot runner plate 3.
In this embodiment, preferably, a plurality of heat insulating gaskets 6 are provided on both the upper and lower end surfaces of the hot runner plate assembly.
In this embodiment, it is preferable that the top portions of the front and rear hot runner plates 2 and 3 are symmetrically provided with elongated multi-layered heat insulating spacers 6 at regions avoiding the nozzles and the screw holes, and the top portions of the left and right hot runner plates 4 and 5 are provided with square multi-layered heat insulating spacers 6.
In this embodiment, it is preferable that the bottom surface of the hot runner plate assembly is provided with three multi-layered heat insulating gaskets 6 having the same size as the bottom portions of the left hot runner plate 4, the right hot runner plate 5, the front hot runner plate 2, and the rear hot runner plate 3, respectively.
By the arrangement of the structure, the multilayer heat insulation gasket with the proper size is designed according to the difference of the upper shape and the lower shape of the hot runner plate assembly, so that the solid contact thermal resistance is generated under the condition of not influencing the operation of the whole structure, and the purpose of reducing heat transfer is achieved.
In this embodiment, the ring-shaped fastening block 1 is preferably provided with a pair of pin holes 7, and the pin holes 7 are provided.
In this embodiment, it is preferable that screw holes are also provided at the top of the left and right hot runner plates 4 and 5 corresponding to the pin holes 7, and the pin holes 7 and the screw holes are coaxially provided and fastened by passing through pins.
