Description

Cleaning head production mold and its products Technical Field

[0001] The invention provides a production mold, in particular to a cleaning head production mold and a product thereof. Background Art

[0002] The existing pipe cleaning head production mold is described as an example of the inventor's previous research and development of Taiwan Patent Certificate No. TW I481451. Please refer to Figures 1 and 2. The pipe cleaning head production mold 9 includes a base 91, a mold set 92, multiple positioning groups 93, a top seat 94 and a cover 95. Among them, the positioning groups 93 are provided with positioning members 931 and extend through the positioning holes 921 of the mold set 92 respectively. The inner sides of the positioning holes 921 are then locked with the nuts 932 and the washers 933 one by one on the positioning members 931, so that the positioning groups 93 are located in the mold set 92. The grooves are engraved to form a mold for pouring the base material. After the pipe cleaning head 90 is completed, the cover 95 and the top seat 94 are first removed. Then, the outer screw portions 930 of the positioning members 931 are loosened from the inner screw holes 920 of the positioning holes 921 of the mold set 92, and the front end protruding shafts 9311 of the positioning members 931 are loosened from the inner screw holes 9321 of the nuts 932. Then, the centers of the positioning members 931 are pulled out and the screw fixing elements 96 are loosened. Finally, the mold set 92 is separated before the pipe cleaning head 90 can be removed. Disassembly is troublesome and time-consuming, so as shown in Figures 3 and 4, a pipe cleaning head 90 is completed, which has multiple concave holes 900 corresponding to the centers of the positioning members 931 and a concave surface 901 at the upper and lower ends; thereby, the nuts 932 and the washers 933 corresponding to the centers of the concave holes 900 of the pipe cleaning head 90 are respectively integrally formed with the base material, and the inner screw holes 9321 of the nuts 932 are corresponding to the centers of the concave holes 900 of the pipe cleaning head 90, and the plurality of pads 902 are used to form the base material. A plurality of screw rods 903 are respectively inserted into the recessed holes 900, and each screw rod has a tungsten steel particle 904 on the outer side thereof. The screw rods 903 are respectively extended through the pads 902 to be screwed correspondingly to the inner threaded holes 9321 of the nuts 932. The screw rods 903 are protruded around the surface of the pipe cleaning head 90 so that the large ends of the screw rods 903 protrude outside the pipe cleaning head 90. The pipe cleaning head 90 then uses the tungsten steel particles 904 respectively provided on the outer sides of the screw rods 903 to strengthen the strength of the screw rods 903, thereby facilitating cleaning the inner wall of the pipe.

[0003] Continuing with the above, referring again to FIG. 5 , when a smaller pipe cleaning head 90A is manufactured using the existing pipe cleaning head production mold 9, if the nuts 932 are not assembled in sufficient numbers as shown in FIG. 5 , each nut 932 may be too large to be densely packed together. This may even cause each nut 932 to occupy a large space, making it easy for the nuts 932 to collide with each other, resulting in insufficient tungsten steel particles 904 on the outer sides of the screws 903 installed on the outer periphery of the smaller pipe cleaning head 90A. The above-mentioned defects in the prior art are the shortcomings that those skilled in the art are eager to improve.

[0051] Best Mode for Carrying Out the Invention

[0052] The technical content, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings.

[0053] 6 to 8 , the present invention is a first embodiment of a cleaning head production mold. The cleaning head production mold 1 includes a base 2 , a body 3 , a positioning body 4 , and an upper cover 5 .

[0054] Please refer to Figures 6 to 8. A first accommodating space 21 is recessed inwardly at the top of the base 2, and a first convex inlay 22 is provided above the outer periphery of the base 2. A first annular groove 23 is provided outwardly at the outer periphery of the first convex inlay 22. The base 2 is easily removed from the mold due to the first annular groove 23 having an outer diameter larger than that of the first convex inlay 22.

[0055] A circular shaping space 31 is formed inside the main body 3, so that the inner wall 30 of the main body 3 is formed into a circular flat shape, and the upper end and lower end of the shaping space 31 of the main body 3 are respectively provided with a first upper recess 32 and a first lower recess 33 with an inner diameter larger than the inner diameter of the shaping space 31. The first lower recess 33 is correspondingly nested with the first convex inlay 22 of the base 2.

[0056] The positioning body 4 is a sheet-shaped, bendable plate disposed on both ends of the inner wall 30 of the body 3 and abutted against each other. The positioning body 4 has a plurality of positioning holes 41. In one embodiment, the positioning holes 41 of the positioning body 4 are arranged in a threaded pattern at intervals, and opposite sides of the positioning body 4 form opposing oblique edges 411.

[0057] The upper cover 5 is positioned over the top of the shaping space 31 of the main body 3. The upper cover 5 includes a through hole 51 on the inner side of the upper surface of the upper cover 5, a second accommodating space 52 at the bottom of the upper cover 5 and communicating with the through hole 51, and a cover 56 disposed above the upper cover 5 and enclosing the shaping space 31. The upper cover 5 is provided with at least one venting slot 53 on its upper surface that communicates with the through hole 51 and the shaping space 31. A second convex inlay 54 is disposed below the outer periphery of the upper cover 5 and is nested with the first upper recess 32 of the main body 3. A second annular groove 55 is also disposed outwardly from the outer periphery of the second convex inlay 54. The second annular groove 55, which has an outer diameter larger than that of the second convex inlay 54, facilitates removal of the upper cover 5 from the mold. The cover 56 includes an injection hole 561 located in the center of the cover 56 and communicating with the shaping space 31, and a convex cover 562 located at the bottom of the cover 56 and inserted into the through hole 51. The injection hole 561 is used to inject the substrate 7 (as shown in FIG7 ). The outer periphery of the bottom of the convex cover 562 is formed with at least one cut edge 5621. In one embodiment, four cut edges 5621 are provided. When the convex cover 562 is inserted into the through hole 51 and covers the upper cover 5, a gap 563 is formed between the cut edge 5621 of the convex cover 562 and the through hole 51, which is connected to the venting slot 53 and the shaping space 31. The gap 563 and the venting slot 53 allow the substrate 7 injected into the shaping space 31 to expand and release (as shown in FIG8 ). By means of these components, the cleaning head production mold 1 is formed, in which the positioning body 4 is formed simultaneously with the cleaning head 8 during the process of injecting the substrate 7. The cleaning head 8 made by the cleaning head production mold 1 is small-sized, and the cleaning head production mold 1 can also be made into large-sized cleaning heads (not shown) to facilitate removal and demoulding.

[0058] Continuing with the above, referring again to Figures 6 to 10B , the inner diameter of the first protruding inlay 22 cannot be larger than the inner diameter of the shaping space 31, and the inner diameter of the second protruding inlay 54 cannot be larger than the inner diameter of the shaping space 31. More specifically, the first accommodating space 21 and the second accommodating space 52 are the tapered shaped spaces below and above the cleaning head 8.

[0059] 6 to 10B , the process of manufacturing the cleaning head 8 is as follows: first, the positioning body 4 is bendably disposed on the inner wall 30 of the main body 3 , and the wear-resistant parts 42 are respectively tightly fitted into the positioning holes 41 of the positioning body 4 . Among them, the wear-resistant parts 42 are wear-resistant materials in a conical shape and are arranged in a threaded shape. The wear-resistant parts 42 respectively include a larger end 421 and a smaller end 422. The larger ends 421 respectively protrude around the shaping space 31, and the smaller ends 422 are respectively gradually reduced from the larger ends 421 and tightly sleeved in the positioning holes 41, so that the smaller ends 422 and the positioning holes 41 form a tight extrusion fit and are respectively inserted and positioned without passing through, so that the smaller ends 422 of the wear-resistant parts 42 are at most flush with the positioning holes 41, and then the first convex inlay 22 of the base 2 is correspondingly sleeved with the first lower recess 33 of the main body 3, and the second convex inlay 54 of the upper cover 5 is correspondingly sleeved with the first upper recess 32 of the main body 3, and then the convex cover body 562 at the bottom end of the cover 56 is abutted. At the top of the shaping space 31, the base material 7 of the cleaning head is filled from the injection hole 561 to the shaping space 31 (as shown in Figures 7 and 8). The base material 7 will flow into the positioning body 4 of the inner wall 30 of the main body 3, and the heat dissipation effect of the injected base material 7 is provided by the exhaust slot 53 on the upper surface of the upper cover 5 (as shown in Figure 8). Then, the base material 7 of the cleaning head is formed into a cleaning head 8 through molding processing, as shown in Figure 9. When the cleaning head 8 is completed, the cover 56 and the upper cover 5 are first taken off, and then the positioning body 4 is taken out from the flat inner wall 30 of the main body 3, so that the positioning body 4 can be easily pulled out from the outer periphery of the cleaning head 8. As shown in Figures 10A and 10B, the cleaning head 8 with the wear-resistant parts 42 arranged on the surface is completed, whereby the wear-resistant parts 42 of the cleaning head 8 are respectively integrated with the base material 7. The cleaning head 8 includes a convex cap 81 disposed oppositely at the upper and lower ends of the cleaning head 8, a cylindrical body 82 located between the two convex caps 81 and having an outer diameter smaller than the convex wall 811 at the bottom end of the convex cap 81, and wear-resistant parts 42 arranged in a threaded pattern and spaced apart on the outer surface of the cylindrical body 82. The larger ends 421 of the wear-resistant parts 42 are positioned and fixed in the cylindrical body 82, while the smaller ends 422 of the wear-resistant parts 42 are disposed around the outer surface of the cylindrical body 82 relative to the larger ends 421 of the wear-resistant parts 42. Because the wear-resistant parts 42 are made of conical wear-resistant material, the smaller ends 422 of the wear-resistant parts 42 are used to clean the inner wall of the pipeline, making the entire production mold 1 simple to manufacture and significantly reducing costs, thereby facilitating demoulding.

[0060] In one embodiment, as shown in Figures 11 and 12, another embodiment of the wear-resistant parts 42, each of the wear-resistant parts 42 further includes a positioning part 43, and each of the positioning parts 43 has a hole 431. The holes 431 are respectively used for inserting the smaller ends 422 of the wear-resistant parts 42, so that the outer peripheries of the larger ends 421 of the wear-resistant parts 42 are respectively inserted and positioned from the holes 431 without passing through, so that the positioning parts 43 and the larger ends 421 of the wear-resistant parts 42 are positioned, formed and fixed inside the cylinder 82 together. The manufacturing method and function are the same as the manufacturing method and function of the wear-resistant parts 42 disclosed in Figure 6, and will not be repeated here.

[0061] Referring again to FIG. 13 and FIG. 14 , another embodiment of the wear-resistant members 42a is generally the same as that shown in FIG. 6 , except that the wear-resistant members 42a are tapered wear-resistant materials and are arranged in a threaded pattern. Each of the wear-resistant members 42a further includes a protrusion 420a perpendicularly connected to the larger end 421a of the wear-resistant members 42a, and the smaller ends 422a of the wear-resistant members 42a taper from the larger ends 421a and respectively protrude around the outer surface of the cylindrical body 82. The manufacturing method and function of the wear-resistant members 42a are the same as those of the wear-resistant members 42 disclosed in FIG. A detailed description thereof will not be given here.

[0062] Referring again to another embodiment of the wear-resistant parts 42b shown in Figures 15 and 16, which are roughly the same as those shown in Figures 6 and 13, the only difference is that the wear-resistant parts 42b each further include a protrusion 420b that is vertically embedded in the larger ends 423b of the wear-resistant parts 42b, and the smaller ends 424b of the wear-resistant parts 42b are gradually tapered from the larger ends 423b and respectively protrude around the outer surface of the cylinder 82, wherein the protrusions 420b are respectively provided with an embedding end 421b facing the larger ends 423b of the wear-resistant parts 42b and having an embedding hole 422b, and the embedding holes 422b are respectively used for the larger ends 423b of the wear-resistant parts 42b to be embedded and fixed. The larger ends 423b and smaller ends 424b of the wear-resistant members 42b are tapered wear-resistant material and arranged in a threaded pattern, so that the protrusions 420b and the larger ends 423b of the wear-resistant members 42b are respectively positioned, formed, and fixed within the connector 82. The manufacturing method and function of the wear-resistant members 42b are similar to those of the wear-resistant members 42 and 42a disclosed in Figures 6 and 13, and will not be further described here.

[0063] Referring again to the second embodiment of the cleaning head production mold shown in Figures 17 to 19, this cleaning head production mold 1c comprises a base 2, a body 3, a positioning body 4c, and a top cover 5, which is substantially the same as that shown in Figure 6, except that the positioning body 4c is a sheet-shaped, bendable body that is disposed on both ends of the inner wall 30 of the body 3 and abuts against each other.
