Description
Technical Field
The utility model relates to the technical field of casting or injection molding equipment, in particular to a mold nozzle assembly.
Background
In the casting or injection molding process, the cavity is fed through a nozzle in a mold. In the actual operation process, after the die is used for a long time, the nozzle can be worn or is wrongly used, and the nozzle is required to be replaced at the moment.
The prior art nozzle assembly structure is shown in fig. 1 and 2, and comprises a cylindrical nozzle 1', a mounting boss 2' surrounding and connected to the outer cylindrical surface of the cylindrical nozzle 1', and a mounting plate 3'. The mounting plate 3 'is provided with an opening 31' for accommodating the cylindrical nozzle 1', three first threaded holes 32' are arranged on the periphery of the opening 31', three second threaded holes 21' are also penetrated through the mounting boss 2', the lower part of the cylindrical nozzle 1' is inserted into the opening 31', the mounting boss 2' is abutted against the surface of the mounting plate 3', and the first threaded holes 32' are aligned with the second threaded holes 21 'one by one and then fixedly connected through screws 4'.
When the cylindrical nozzle 1' needs to be replaced, the cylindrical nozzle 1' is separated from the mounting plate 3' by removing the screw, and a new nozzle is replaced.
Although the above structure can replace the nozzle, the disadvantage is that: since the mounting boss 2' completely covers the position of the first screw hole 32' on the mounting plate 3' at the time of mounting, blind alignment operation is required for the first screw hole 32' to be aligned with the second screw hole 21', and small deviation may cause misalignment of the first screw hole 32' with the second screw hole 21' to cause mounting failure. Therefore, the structure needs longer time when being installed, which is not beneficial to improving the production efficiency.
Therefore, a new solution is needed to solve the above-mentioned problems.
Disclosure of Invention
In order to solve the problems generated by the prior art, the utility model provides a die nozzle assembly which is used for solving the problem of how to quickly improve the nozzle installation efficiency.
In order to achieve the above purpose, the die nozzle assembly of the utility model can adopt the following technical scheme:
the die nozzle assembly comprises a mounting plate, a nozzle and a screw, wherein a mounting boss surrounding the nozzle is arranged on the periphery of the nozzle, the mounting plate is provided with an opening for accommodating the bottom of the nozzle and the mounting boss, a circle of step part for bearing the mounting boss is arranged in the opening, and when the mounting boss is accommodated in the opening and is borne on the step part, the upper surface of the mounting boss and the upper surface of the mounting plate are positioned on the same plane; the upper surface of mounting panel still is equipped with two at least screw holes, and when the screw was fixed in the screw hole, the head of screw was pressed at the upper surface of installation boss.
Furthermore, the number of the threaded holes is only two, and the threaded holes are symmetrically arranged on two sides of the opening.
Further, the nozzle is a cylindrical nozzle, the outer edge of the installation boss is circular, and the step part is circular.
Further, when the screw is fixed to the threaded hole, the head portion of the screw is pressed against the upper surface of the mounting plate and the head portion of the screw is pressed against the upper surface of the mounting boss.
Further, the screw is an inner hexagon screw.
The beneficial effects are that: compared with the prior art, the die nozzle assembly provided by the utility model avoids shielding of the mounting boss on the threaded hole of the mounting plate by the way of accommodating the mounting boss in the opening and then fixedly mounting the mounting boss by the screw, so that the operation of thread fixing can be rapidly performed during mounting operation, and the mounting efficiency is improved. Meanwhile, through the structure that the installation boss is accommodated to the opening, the mutual matching between the installation boss and the opening plays a role in positioning at the same time, positioning points do not need to be found any more, three-point positioning by adopting three screws like the prior art is not needed any more, and the installation efficiency is improved as well.

Detailed Description
The present utility model is further illustrated in the accompanying drawings and detailed description which are to be construed as exemplary only and not limiting the scope of the utility model, since modifications to the utility model in the art will fall within the scope of the utility model which is defined by the appended claims after reading the utility model.
Referring to fig. 3 to 5, the utility model discloses a mold nozzle assembly, which comprises a mounting plate 1, a nozzle 2 and a screw 3. In this embodiment, the nozzle 2 is a cylindrical nozzle, and a mounting boss 4 surrounding the nozzle 2 is provided on the periphery of the nozzle 2. The upper surface of the mounting plate 1 is provided with an opening 11 which is concave downwards and is used for accommodating the bottom of the nozzle 2 and the mounting boss 4, and a circle of step parts 12 which bear the mounting boss are arranged in the opening 11. When the mounting boss 4 is received in the opening 11 and carried on the stepped portion 12, the upper surface of the mounting boss 4 is on the same plane as the upper surface of the mounting plate 1, i.e., the thickness of the mounting boss 4 is the same as the depth of the stepped portion 12 to the upper surface of the mounting plate 1. The upper surface of the mounting plate 1 is also provided with two threaded holes 13. When the screw 3 is fixed to the screw hole 13, the head 31 of the screw is partially pressed against the upper surface of the mounting plate 1 and partially pressed against the upper surface of the mounting boss 4 to fix the mounting plate 1 and the nozzle 2 to each other. Because the mounting boss 4 can not produce the shielding to the screw hole 13 of mounting panel, so can carry out the operation of screw thread fixation fast, improve installation effectiveness. Meanwhile, the outer edge of the installation boss 4 is circular, and the step part 12 is circular, so that the mutual matching between the installation boss 4 and the opening 11 plays a role in positioning at the same time, locating points do not need to be found any more, and the installation efficiency is improved.
