Description

Technical Field

[0001] The utility model relates to the technical field of hot water kettles, in particular to a mould for making kettle bodies. Background Art

[0002] The kettle body is generally formed by injection molding. Some kettle bodies need to be provided with a transparent water gauge to facilitate observation of the water level. Figure 1 As shown in the figure, there is a bone in the middle of the water gauge. In order to smoothly demold, this bone will usually extend to the top of the pot body. This will have the following disadvantages: 1. During injection molding production, the transparent water gauge needs to be placed manually, which is easy to be inaccurately positioned; 2. During injection molding production, the surface of the pot body with the bone will have air marks and shrinkage marks, which will affect the surface appearance of the pot body and reduce product quality.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] Reference Figures 2 to 6 The utility model discloses a mold for making a kettle body, comprising a first mold 10 and a second mold 20, wherein a mold core 21 and a positioning block 22 are arranged on the second mold 20, and the first mold 10 and the second mold 20 are closed so that an annular mold cavity is formed between the mold core 21 and the first mold 10 for injection molding the kettle body, and a first positioning groove 211 penetrating through the top of the mold core 21 is arranged on the mold core 21, and the positioning block 22 is clamped with the first positioning groove 211 and the positioning block 22 can be disengaged from the top of the mold core 21 from bottom to top along the first positioning groove 211, and a clamping structure is arranged between the positioning block 22 and the water gauge 30 to realize a detachable connection.

[0023] The utility model also protects a process, which is applied to the above-mentioned mold for making a kettle body, comprising the following steps: Step 1, inserting the positioning block 22 into the first positioning groove 211;

[0024] Step 2, the water gauge 30 is engaged with the positioning block 22, so as to realize the positioning of the water gauge 30;

[0025] Step 3, closing the first mold 10 and the second mold 20, and injection molding to form the pot body;

[0026] Step 4, separating the first mold 10 and the second mold 20, pulling the pot body out from the mold core 21, and the positioning block 22 follows the pot body out of the first positioning groove 211;

[0027] Step 5, separate and remove the positioning block 22 from the water gauge 30 on the pot body, and put it back into the first positioning groove 211 on the mold core 21 to perform injection molding positioning for the next pot body.

[0028] That is, a positioning block 22 is placed in the first positioning groove 211 of the mold core 21, which can replace the bone position in the prior art, and the positioning block 22 is engaged with the water gauge 30, so that the water gauge 30 can be accurately positioned; when the pot body is injection-molded, the positioning block 22 will follow the pot body out of the mold and come out of the first positioning groove 211. After the pot body is taken out, since the positioning block 22 is engaged with the water gauge 30, Figure 5 , the positioning block 22 can be separated from the water gauge 30 on the pot body by using the positioning block removal piece 40 (the positioning block removal piece 40 is provided with a matching groove 41 that can be engaged with the end of the positioning block 22) and then put back into the mold for the next injection molding production. The mold and process for making the pot body can not only accurately position the water gauge 30, but also will not form a bone position on the pot body, such as Figure 6 There will be no air marks or shrinkage marks on the inner surface of the pot body, which effectively improves product quality.

[0029] Furthermore, there are multiple positioning blocks 22. After the injection molding of the current pot body is completed, there is no need to wait for the positioning block 22 that has not been removed from it. Another positioning block can be directly placed on the mold core 21 to carry out the injection molding of the next pot body. The corresponding positioning block 22 on the pot body after the injection molding is completed can be taken out and can still be reused, thereby improving the injection molding efficiency.

[0030] Further, such as Figure 3 As shown, it also includes a second positioning groove 212 located below the first positioning groove 211, and the center line of the second positioning groove 212 coincides with the center line of the first positioning groove 211. The upper and lower ends of the water ruler 30 are respectively provided with positioning parts, and the positioning block 22 is provided with a groove 221 to be clamped with the upper end positioning part of the water ruler 30, and the second positioning groove 212 is clamped with the lower end positioning part of the water ruler 30, so that the upper and lower ends of the water ruler 30 are positioned, the positioning is more accurate, and the shaking of the water ruler 30 affects the positioning accuracy.

[0031] In some embodiments, the groove 221 is T-shaped, and the upper positioning portion of the water gauge 30 is a transverse positioning rib 31. When the pot body is formed by injection molding, the groove 221 will be squeezed and deformed to a certain extent due to the injection pressure. Therefore, the T-shaped groove 221 has a certain deformation space, which is convenient for separating the positioning block 22 from the transverse positioning rib 31 and removing it from the pot body.

[0032] Furthermore, the second positioning groove 212 is strip-shaped and connected to the first positioning groove 211, which is convenient for machining the first positioning groove 211 and the second positioning groove 212 together. The lower end positioning portion of the water gauge 30 is a vertical positioning rib 32 to facilitate the clamping connection with the second positioning groove 212.

[0033] Furthermore, the shape of the first positioning groove 211 is wide at the top and narrow at the bottom, which facilitates the removal and insertion of the second positioning block 22 and improves production efficiency.

[0034] In some embodiments, a positioning boss 213 is provided at the bottom of the first positioning groove 211, and a corresponding snap-in slot is provided on the positioning block 22, or a snap-in slot is provided at the bottom of the first positioning groove, and a positioning boss 213 is provided on the positioning block 22 to fix and position the positioning block 22, thereby preventing the first positioning groove 211 from being too large, affecting the placement of the positioning block 22 or placing it unsteadily, and further improving the positioning accuracy of the water gauge 30.

[0035] It is easy for those skilled in the art to understand that the above preferred embodiments can be freely combined and superimposed without conflict.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
