[0016] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments given are not intended to limit the present utility model.

[0017] Embodiment

[0018] A combined fixture for the coplanarity of inner and outer guide pieces is applied to the inner and outer guide piece assembly and drying equipment, such as Figures 1-3As shown in the figure, it includes a combined bottom plate 1 of a guide piece die core, an inner guide piece end foot pressing block 2 and an outer guide piece end head pressing block 3 which are assembled at the upper end of the combined bottom plate 1 of the guide piece die core and cooperate with each other, several positioning rods 4 which pass through the combined bottom plate 1 of the guide piece die core and are assembled with the inner guide piece end foot pressing block 2 and the outer guide piece end head pressing block 3, an outer guide piece 5 which is placed in the middle of the upper end of the combined bottom plate 1 of the guide piece die core and is extruded by the outer guide piece end head pressing block 3, an inner guide piece 6 which is placed in the middle of the upper end of the combined bottom plate 1 of the guide piece die core and is extruded by the inner guide piece end foot pressing block 2, and a coplanarity ejector pin 7 which is embedded at the upper side of the outer guide piece end head pressing block 3. The coplanarity ejector pin 7 faces the outer guide piece 5 and can be disassembled and replaced according to the specification of the outer guide piece 5.

[0019] The combined bottom plate 1 of the guide piece die core includes a bottom plate body 11, placing grooves 12 which are opened at both ends above the bottom plate body 11 and are used for placing the inner guide piece end foot pressing block 2 and the outer guide piece end head pressing block 3, and an assembly rib 13 which is arranged between the two placing grooves 12 and is used for placing the outer guide piece 5 and the inner guide piece 6.

[0020] The bottom plate body 11 is equidistantly penetrated with a plurality of positioning rod insertion holes 111. The positioning rod insertion holes 111 are located at the upper end of the bottom plate body 11 and are communicated with the placing grooves 12.

[0021] The assembly rib 13 is provided with inner guide piece clamping protrusions 131. Between every two inner guide piece clamping protrusions 131, there is an outer guide piece limiting protrusion 132 with a material taking groove. There are ejection holes 133 which are arranged around the inner guide piece clamping protrusions 131 and penetrate downward. When placing the outer guide piece 5 and the inner guide piece 6, first buckle the inner guide piece 6 into the inner guide piece clamping protrusions 131, then buckle the outer guide piece 5 outside the inner guide piece 6, use the outer guide piece limiting protrusion 132 to position the outer guide piece 5, and then use the inner guide piece end foot pressing block 2 and the outer guide piece end head pressing block 3 to perform extrusion and fixation. After the dispensing and drying are completed, the dried product is ejected through the ejection cylinder at the position of the combined fixture for the coplanarity of the inner and outer guide pieces passing through the ejection holes 133.

[0022] The lower end of the assembly rib 13 is also provided with a horizontal through hole 134.

[0023] Specifically, the horizontal through hole 134 corresponds to the positioning rod insertion holes 111. Therefore, after the inner guide piece end foot pressing block 2 and the outer guide piece end head pressing block 3 are placed in the placing grooves 12, in order to prevent the left and right swing from affecting the assembly of the outer guide piece 5 and the inner guide piece 6, the positioning rods 4 are sequentially passed through the positioning rod insertion holes, the outer guide piece end head pressing block, the horizontal through hole, the inner guide piece end foot pressing block and the positioning rod insertion holes, so as to play a role in guiding and preventing deviation for the inner guide piece end foot pressing block 2 and the outer guide piece end head pressing block 3.

[0024] The inner guide piece end foot pressing block 2 includes an inner guide piece end foot pressing block body 21 with one side protruding towards the outer guide piece end head pressing block 3, a first spring member 22 embedded in the other side of the inner guide piece end foot pressing block body 21, and an inner guide piece end foot pressing block guiding hole 23 passing through the inner guide piece end foot pressing block body 21 for inserting the positioning rod 4. The side of the inner guide piece end foot pressing block body 21 where the first spring member 22 is embedded contacts the placement groove 12, and can, after assembling the outer guide piece 5 and the inner guide piece 6, under the pressure of the first spring member 22, push the inner guide piece end foot pressing block body 21 into contact with the inner guide piece 6 to perform pre-flattening treatment on the inner guide piece 6.

[0025] The outer guide piece end head pressing block 3 includes an outer guide piece end head pressing block body 31 with one side protruding towards the inner guide piece end foot pressing block 2, a second spring member 32 embedded in the other side of the outer guide piece end head pressing block body 31, an outer guide piece end head pressing block guiding hole 33 passing through the outer guide piece end head pressing block body 31 for inserting the positioning rod 4, and a needle groove 34 opened on the side of the outer guide piece end head pressing block 3 facing the outer guide piece 5 for inserting the coplanarity thimble 7.

[0026] It should be further noted that the side of the outer guide piece end head pressing block body 31 where the second spring member 32 is embedded contacts the placement groove 12, and can, after assembling the outer guide piece 5 and the inner guide piece 6, under the pressure of the second spring member 32, push the outer guide piece end head pressing block body 31 towards the outer guide piece 5 and use the coplanarity thimble 7 inserted in the needle groove 34 to abut against the outer guide piece 5, so as to perform coplanarity treatment on the outer guide piece 5.

[0027] The above embodiments of the present invention do not limit the protection scope of the present invention. The implementation manners of the present invention are not limited thereto. All such modifications, substitutions or changes made to the above structure of the present invention according to the above content of the present invention, in accordance with the common general technical knowledge and conventional means in the art, without departing from the above basic technical idea of the present invention, shall fall within the protection scope of the present invention.
