Example (b):

referring to fig. 1 and 2, a bottleneck forming structure with a wear-resistant block 20 includes two bottleneck forming plates 10, the two bottleneck forming plates 10 are disposed opposite to each other, and the two bottleneck forming plates 10 can be close to or far away from each other to close or open the mold. Specifically, forming concave positions 12 are arranged on the bottle mouth forming plates 10, and the forming concave positions 12 on the two bottle mouth forming plates 10 can be matched to form a forming opening 30 during mold closing. In addition, the side wall of the forming concave position 12 is provided with a wear-resistant block 20, the wear-resistant block 20 is detachably connected with the side wall of the forming concave position 12, and the inner side of the wear-resistant block 20 is formed into a wear-resistant forming surface 21.

On the basis of the structure, use the utility model discloses a during bottleneck forming structure with wear-resisting piece 20, during the shaping, accessible actuating mechanism on the mould organism drives two bottleneck profiled sheeting 10 and is close to each other and forms, and two bottleneck profiled sheeting 10 can be being close to each other and become mouthful 30, stretch into after this into the profiled sheeting 50 in, carry out the injection moulding of bottleneck can, after shaping a period, bottleneck cooling shaping, go on the demolding can.

In the process, the bottle mouth forming part 50 is in friction fit with the wear-resistant forming surface 21 in the forming concave position 12, so that the wear of the bottle mouth forming plate 10 is reduced, the wear scraps cannot be generated, the product forming quality is improved, better precision can be still kept during repeated mold closing and mold opening, and the service life of the bottle mouth forming plate 10 is prolonged. And wear-resisting piece 20 and bottleneck profiled sheeting 10 can be dismantled and be connected, directly change wear-resisting piece 20 after wearing and tearing can, need not to change monoblock bottleneck profiled sheeting 10, resources are saved.

Furthermore, the wear-resistant molding surface 21 is gradually inclined inwards from top to bottom, and in the process of opening or closing the mold, the longitudinal driving force can be decomposed through the inclined wear-resistant molding surface 21, so that the force applied to the wear-resistant molding surface 21 is reduced, the friction can be reduced, and the wear resistance can be improved. Of course, the inclined surfaces are matched in the mold opening and closing process, so that the mold opening and closing can be guided to be stable.

Further, a mounting groove can be arranged at the top end of the side wall of the molding concave position 12, and the bottom end of the side wall of the molding concave position 12 is formed into an abutting wall 11, wherein the abutting wall 11 is positioned outside the mounting groove. Correspondingly, the wear-resistant block 20 has a mounting end 22 and an abutting end 23, when the wear-resistant block 20 is assembled, the mounting end 22 of the wear-resistant block 20 can be embedded in the mounting groove, so that the inner side of the abutting end 23 abuts against the abutting wall 11, and the wear-resistant molding surface 21 is arranged on the outer side of the abutting end 23. Therefore, the top end of the wear-resistant block 20 is mounted and limited by the mounting groove, and the abutting end 23 can abut against the abutting wall 11, so that the wear-resistant block 20 is prevented from shifting in the die opening or die closing process, and the forming process is more stable.

More specifically, still can be equipped with spacing recess 24 between installation end 22 and the end 23 that leans on, in the lateral wall embedding spacing recess 24 of above-mentioned mounting groove, after wear-resisting piece 20 assembles, installation end 22 inlays the dress in the mounting groove, and the lateral wall of mounting groove can correspond inlays the dress in spacing recess 24, leans on end 23 to lean on wall 11 simultaneously, can carry out spacingly in three directions, and assembly structure is more stable, and the shaping precision is higher.

Further, the mounting end 22 is connected to the bottom wall of the mounting groove through a bolt 40, that is, the wear-resistant block 20 can be disassembled and assembled through the bolt 40, and the wear-resistant block 20 is more convenient to replace.

Further, be equipped with two at least shaping concave position 12 on bottleneck profiled sheeting 10, and two at least shaping concave position 12 one-to-one on two bottleneck profiled sheeting 10, so, when the shaping, two bottleneck profiled sheeting 10 can form two at least shaping mouths 30 after the compound die, two at least products of one shot forming, and shaping efficiency is higher.

Further, the wear-resistant block 20 is made of a wear-resistant material, and it should be noted that the wear-resistant property may be selected from other wear-resistant materials such as polymer and composite wear-resistant materials, such as wear-resistant steel plates, wear-resistant welding rods, wear-resistant ceramics, wear-resistant rubber, and the like in the prior art.
