Description

Technical Field

[0001] This utility model relates to the field of gear reducer technology, and in particular to a tablet pressing mold. Background Technology

[0002] The tablet compressor is an oral health care device. During the manufacturing process, the outer shell of the tablet compressor is mostly processed using injection molds for mass production. Injection molding specifically refers to injecting molten plastic into the mold cavity under high pressure using an injection molding machine. After cooling and solidification, the molded product is obtained. When using the injection molding mold, in order to achieve a rapid cooling effect on the plastic part, a corresponding built-in circulating water cooling mechanism is generally set on the injection molding mold. Existing water cooling mechanisms mostly have guide holes directly opened on the mold, but the guide holes are mostly direct current channels, which limits the contact area between the cooling water and the plastic part, resulting in an ineffective cooling effect on the plastic part and is not conducive to the processing of the tablet compressor plastic part. Therefore, we propose a tablet compressor mold. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a tableting mold. This invention solves the problem that existing water-cooling mechanisms often involve directly opening guide holes in the mold, but these guide holes are mostly direct-flow channels, resulting in limited contact area between the cooling water and the plastic part, thus limiting the cooling effect on the plastic part and hindering the processing of the tableting plastic part.

[0004] A tablet compression mold of this utility model includes a lower mold base, with support seats on both sides above the lower mold base, a lower module above the support seats, an upper mold base above the lower module, and an upper module matching the lower module below the upper mold base. The lower module and the upper module are provided with mounting grooves on the side away from each other, and cooling components are provided in both the upper mold base and the upper module.

[0005] The cooling assembly includes a fixed plate with connecting plates on both sides. One side of the fixed plate has an inlet pipe, and the other side of the fixed plate away from the inlet pipe has an outlet pipe. A guide groove is formed on the side wall of the fixed plate away from the connecting plates, and the two ends of the guide groove are connected to the inlet pipe and the outlet pipe, respectively.

[0006] In the above scheme, both the lower module and the upper module are provided with limiting platforms that match the connecting plate.

[0007] In the above scheme, the connecting plate is provided with a plurality of first threaded holes arranged at equal intervals, and the lower module and the upper module are provided with second threaded holes that match the first threaded holes. Bolts are inserted into the first threaded holes and the second threaded holes.

[0008] In the above scheme, the cross-section of the guide channel is S-shaped.

[0009] In the above scheme, the upper module is provided with a punch in the middle of the side near the lower module, and the lower module is provided with a die that matches the punch.

[0010] In the above scheme, an injection port is provided at the middle of the upper end of the upper mold base, and a guide hole matching the injection port is provided on the fixed plate.

[0011] Compared with related technologies, this utility model has the following beneficial effects:

[0012] This invention provides a tablet compression mold. A cooling component is fixedly installed inside an installation groove. One side of the guide groove on the fixed plate is in contact with the lower and upper modules. Coolant enters the guide groove through an inlet pipe and flows out through an outlet pipe via the guide groove. As the coolant flows within the guide groove, it rapidly dissipates heat from the lower and upper modules. The S-shaped cross-section of the guide groove increases the contact area between the coolant and the lower and upper modules. This mold has a simple structure, the cooling component is easy to install and remove, the contact area between the coolant and the lower and upper modules is large, and the cooling component dissipates heat from the mold quickly, effectively improving the processing efficiency of the tablet compression mold.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] like Figure 1-5 As shown, this utility model is a tablet compression mold, including a lower mold base 1, with support bases 2 on both sides above the lower mold base 1, a lower module 3 above the support base 2, an upper mold base 4 above the lower module 3, and an upper module 5 matching the lower module 3 below the upper mold base 4. The lower module 3 and the upper module 5 each have a mounting groove 6 on the side furthest from each other. Cooling components 7 are provided inside both the upper mold base 4 and the upper module 5, and the cooling components 7 can be fixedly installed inside the mounting groove 6.

[0026] The cooling assembly 7 includes a fixing plate 71, with connecting plates 72 on both sides of the fixing plate 71. An inlet pipe 73 is provided on one side of the fixing plate 71, and an outlet pipe 75 is provided on the side of the fixing plate 71 away from the inlet pipe 73. A guide groove 74 is formed on the side wall of the fixing plate 71 away from the connecting plates 72. The two ends of the guide groove 74 are connected to the inlet pipe 73 and the outlet pipe 75, respectively. When the cooling assembly 7 is installed inside the mounting slot 6, one side of the guide groove 74 on the fixing plate 71 is in contact with the lower module 3 and the upper module 5. Coolant can enter the guide groove 74 through the inlet pipe 73. Through the guidance of the guide groove 74, the coolant can flow out through the outlet pipe 75. When the coolant flows inside the guide groove 74, it can quickly dissipate heat from the lower module 3 and the upper module 5.

[0027] Both the lower module 3 and the upper module 5 are provided with limiting platforms 8 that match the connecting plate 72. The limiting platforms 8 can limit the connecting plates 72 on both sides of the fixing plate 71.

[0028] The connecting plate 72 has a plurality of equidistantly arranged first threaded holes 76. The lower module 3 and the upper module 5 each have second threaded holes 9 that match the first threaded holes 76. Bolts 10 are inserted into the first threaded holes 76 and the second threaded holes 9. The first threaded holes 76 and the second threaded holes 9 have internal threads that match the bolts 10. Through the mutual cooperation between the bolts 10 and the first threaded holes 76 and the second threaded holes 9, the connecting plate 72 can be stably connected to the lower module 3 and the upper module 5. At the same time, it makes it easy to disassemble the cooling component 7, and makes it easier to clean the inside of the guide channel 74 after long-term use.

[0029] The cross-section of the guide channel 74 is S-shaped. The S-shaped cross-section of the guide channel 74 increases the contact area between the coolant and the lower module 3 and the upper module 5, effectively improving the heat dissipation speed of the cooling component 7 on the mold.

[0030] The upper module 5 is provided with a punch 11 in the middle of the side near the lower module 3, and the lower module 3 is provided with a cavity 12 that matches the punch 11. When the molds are in contact with each other, the punch 11 and the cavity 12 form the cavity of the plastic part.

[0031] The upper mold base 4 has an injection port 13 at the middle of its upper end. The fixed plate 71 has a guide hole 77 that matches the injection port 13. The injection port 13 can be used to inject the mold. The guide hole 77 allows the liquefied plastic to flow through the injection hole above the punch 11 into the space between the punch 11 and the die 12, thereby completing the injection molding of the pressed plastic part.

[0032] Specifically, in this utility model, the cooling component 7 is fixedly installed inside the mounting groove 6. One side of the guide groove 74 on the fixing plate 71 is in contact with the lower module 3 and the upper module 5. The coolant enters the guide groove 74 through the inlet pipe 73. Through the guide groove 74, the coolant can flow out through the outlet pipe 75. When the coolant flows inside the guide groove 74, the coolant can quickly dissipate heat from the lower module 3 and the upper module 5. The S-shaped guide groove 74 increases the contact area between the coolant and the lower module 3 and the upper module 5, effectively improving the heat dissipation speed of the cooling component 7 on the mold. Through the mutual cooperation between the bolt 10 and the first threaded hole 76 and the second threaded hole 9, the connecting plate 72 can be stably connected to the lower module 3 and the upper module 5. At the same time, it makes the cooling component 7 easy to disassemble, and makes it easier to clean the inside of the guide groove 74 after long-term use.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
