Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and more specifically, particularly relates to a mold for a dental irrigator of a sharp-corner part. Background Art

[0002] In the manufacture of dental irrigators, sharp-corner parts are key components, requiring a very high sharp angle for the part shape, and there are many challenges in the manufacturing process.

[0003] In order to successfully form such sharp-corner products, the traditional method of using a single integral insert often fails to achieve the ideal effect. This is because during the electrical discharge machining process, the insert will inevitably wear, resulting in a small round corner of 0.2 mm being formed at the deepest part of the machining, which is obviously unacceptable for this part; while using two inserts, due to the lifter near the sharp-corner part and the internal waterway structure, it is very difficult to leave enough width of the step and pillow position at the splicing place, and it is extremely easy to fall off due to stretching when the mold opens and closes. Moreover, the insert is too thin and long, with insufficient machining strength and extremely difficult mold matching; therefore, a mold for a dental irrigator of a sharp-corner part is needed to solve the placement layout problem of the two inserts. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a mold for a dental irrigator of a sharp-corner part to solve the technical problems in the prior art that the traditional single-insert mold will cause a small round corner of 0.2 mm to be formed at the deepest part of the machining, while the two inserts will be too thin and long due to insufficient space, resulting in insufficient machining strength and difficult mold matching.

[0028] The utility model provides a mold for a sharp-corner part irrigator, which includes a first mold core 11 and a second mold core 12. Four processing platforms 14 for placing products 13 to be processed are arranged at the top of the second mold core 12. Four installation grooves 15 are respectively opened on the circumferences of these four processing platforms 14. Forming components are arranged in these four installation grooves 15. The forming component includes a first insert 21. Specifically, a first insert 21 is arranged in each of these four installation grooves 15. A sharp-corner processing groove 22 is opened at the top of each first insert 21. The circumference of the product 13 is clamped in the sharp-corner processing groove 22.

[0029] Please refer to as Figure 2 and Figure 3 shown, the forming component further includes a second insert 23. The bottom of the installation groove 15 is fixedly connected with the second insert 23 through a plurality of screws. A first connection groove 24 is opened at the top of the second insert 23. The first insert 21 is fixedly connected to the bottom of the first connection groove 24 through screws. Both the first insert 21 and the second insert 23 are designed in an annular structure. Through the structure of superposing and installing the first insert 21 and the second insert 23, the problem that a traditional single-insert mold forms a 0.2-mm small round corner at the deepest part during processing is solved. Among them, the first connection groove 24 is opened on the second insert 23, enabling the first insert 21 and the second insert 23 to be sleeved and superposed, saving space and making the overall structure more compact and reasonable. It not only ensures the structural strength of the two inserts but also solves the problem of insufficient strength of traditional double-insert molds. At the same time, it will not cause adverse effects on the inclined top 31, achieving good coordination and balance of multiple functions.
