Technical Field

[0001] The utility model relates to the technical field of polyurethane rod mold structures, in particular to a polyurethane rod mold. Background Art

[0002] Polyurethane is the abbreviation of polyurethane, and its English name is polyurethane. It is a polymer material. Polyurethane is an emerging organic polymer material and is known as the "fifth plastic". It is widely used in many fields of the national economy due to its excellent performance. The product application areas involve light industry, chemical industry, electronics, textiles, medical treatment, construction, building materials, automobiles, national defense, aerospace, aviation, etc. It has low production cost and wide application range, and it cannot be replaced by other substances.

[0003] Before polyurethane leaves the factory, it will be produced into rods so that it can be easily transported to various professional factories. There is currently a mold that can produce multiple polyurethane rods at the same time. When using it, you only need to inject liquid polyurethane into the top of the mold. However, the diameter of the polyurethane rods of this mold is fixed. If you need to produce rods of different diameters, you need to customize the mold again, which wastes resources and increases production costs. Utility Model Content

[0004] The utility model aims to provide a polyurethane rod mold to solve the problem that traditional production molds cannot adjust the rod diameter, waste resources and increase production costs.

[0005] To achieve the above object, the utility model provides the following technical solutions: a polyurethane rod mold, comprising a mold assembly, the mold assembly comprising a liquid injection frame, a mold tube, a plurality of the mold tubes are provided, and the plurality of the mold tubes are linearly arranged at the bottom of the outer wall of the liquid injection frame, a replacement assembly is provided inside the liquid injection frame, and the replacement assembly comprises a tapered hole and a tapered sleeve;

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 In an embodiment of the utility model, a polyurethane rod mold includes a mold assembly 1, the mold assembly 1 includes a liquid injection frame 101, a mold tube 102, a plurality of mold tubes 102 are provided, and the plurality of mold tubes 102 are linearly arranged at the bottom of the outer wall of the liquid injection frame 101, and a replacement assembly 2 is provided inside the liquid injection frame 101, and the replacement assembly 2 includes a tapered hole 201 and a tapered sleeve 202;

[0022] There are multiple conical holes 201, which are linearly arranged at the bottom of the inner wall of the liquid injection frame 101, and one end extends to the bottom of the outer wall of the liquid injection frame 101. The diameter of the bottom end of the inner wall of the conical hole 201 is smaller than the diameter of the top end of the inner wall of the conical hole 201. The conical sleeve 202 is slidably connected to the inner wall of the conical hole 201, and a circular hole is provided on the top of the outer wall of the conical sleeve 202. The top of the mold tube 102 extends to the inner wall of the circular hole and is fixedly connected to the conical sleeve 202.

[0023] In this embodiment: when the mold tube 102 is produced, it is only necessary to fix the tapered sleeve 202 to the mold tubes 102 of different diameters. When the size of the produced polyurethane rod needs to be adjusted, it is only necessary to pass the mold tube 102 of the corresponding size through the tapered hole 201, and make the tapered sleeve 202 on the outer wall of the mold tube 102 fit with the tapered hole 201. At this time, liquid polyurethane can be poured into the injection frame 101. Through the coordination of the above parts, it is only necessary to replace the mold tube 102 to change the product specifications, thereby reducing the size of the parts that need to be replaced when changing the production specifications, thereby solving the problem that the traditional production mold cannot adjust the rod diameter, wasting resources and increasing production costs.

[0024] Please refer to Figures 1 to 4 , the replacement assembly 2 also includes a pressing plate 203;

[0025] The pressing plate 203 is slidably connected to the inner wall of the liquid injection frame 101 , and the top of the outer wall of the pressing plate 203 fits with the bottom of the inner wall of the liquid injection frame 101 .

[0026] In this embodiment: by setting a pressure plate 203, after replacing the mold tube 102 of different specifications, the mold tube 102 will be unable to move through the fit between the outer wall of the conical sleeve 202 and the outer wall of the conical hole 201 and the bottom of the outer wall of the pressure plate 203, thereby ensuring that the liquid polyurethane inside the injection frame 101 can flow into the mold tube 102.

[0027] Please refer to Figures 1 to 4 , the replacement component 2 also includes a through hole 204;

[0028] A plurality of through holes 204 are provided, and the plurality of through holes 204 are linearly arranged on the top of the outer wall of the pressing plate 203 , and the through holes 204 completely penetrate the bottom of the outer wall of the pressing plate 203 .

[0029] In this embodiment: by providing the through hole 204, when the conical sleeve 202 and the mold tube 102 are fixed by the pressing plate 203, the liquid polyurethane inside the injection frame 101 can flow into the mold tube 102, thereby producing a finished polyurethane rod.

[0030] Please refer to Figure 4 The diameter of the inner wall of the through hole 204 is the same as the diameter of the bottom end of the inner wall of the tapered hole 201, and the axis of the through hole 204 and the axis of the tapered hole 201 are on the same straight line.

[0031] In this embodiment: the inner wall diameter of the through hole 204 is the same as the bottom end diameter of the inner wall of the tapered hole 201, and the axis of the through hole 204 and the axis of the tapered hole 201 are on the same straight line, so that the through hole 204 can be connected to the mold tube 102 inside the tapered hole 201, thereby ensuring the convenience of pouring the mold tube 102.

[0032] Please refer to Figures 1 to 4 The outer wall of the conical sleeve 202 is completely fitted with the inner wall of the conical hole 201 , the height of the outer wall of the conical sleeve 202 is exactly the same as the height of the inner wall of the conical hole 201 , and the bottom of the outer wall of the pressing plate 203 is fitted with the top of the outer wall of the conical sleeve 202 .

[0033] In this embodiment: the outer wall of the conical sleeve 202 is completely fitted with the inner wall of the conical hole 201, and the height of the outer wall of the conical sleeve 202 is exactly the same as the height of the inner wall of the conical hole 201, so that when the mold tube 102 needs to be fixed, it is only necessary to fit the pressing plate 203 with the conical sleeve 202 to prevent all the mold tubes 102 and the conical sleeve 202 from sliding, thereby facilitating the staff to inject liquid polyurethane into the mold tube 102.
