Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a set-top box mold with a delayed annular cooling structure. Background Technology

[0002] Set-top box molds are manufacturing tools used to produce plastic parts for set-top box covers. A set-top box is a device that connects a television set to an external signal source, converting compressed digital signals into content that can be displayed on a television screen and presented to the user.

[0003] Existing set-top box molds, such as the set-top box mold with a delayed annular cooling structure disclosed in publication number CN214820424U, although having two opposite flow channel systems for simultaneous water inlet and outlet to improve the heat dissipation efficiency of the lower mold, are inconvenient for simultaneous cooling of the sides and bottom of the mold cavity, and the cooling structure is inconvenient to disassemble for convenient maintenance or repair. Therefore, we propose a set-top box mold with a delayed annular cooling structure. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A set-top box mold with a delayed annular cooling structure includes: a mold body and a cooling assembly; the mold body includes an upper mold and a lower mold at its upper and lower ends; the cooling assembly includes a movable plate movably mounted on the top of the lower mold, a module fixedly disposed in the middle of the movable plate, a mold cavity disposed in the module, a side cooling port disposed on the side of the module, a side cooling channel fixedly installed in the side cooling port, a bottom cooling port disposed at the bottom of the module, and a bottom cooling channel fixedly installed in the bottom cooling port.

[0007] Preferably, the two ends of the side cooling channel are respectively provided with a side water inlet and a side water outlet, and the two ends of the bottom cooling channel are respectively provided with a bottom water inlet and a bottom water outlet.

[0008] Preferably, the outer ends of the side inlet and the bottom inlet are also fixedly installed with inlet connecting sleeves, and the outer ends of the inlet connecting sleeves are also fixedly installed with inlet pipes.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a set-top box mold with a delayed annular cooling structure.

[0026] Example 1:

[0027] Combination Figure 1-6 As shown, the present invention provides a set-top box mold with a delayed annular cooling structure, comprising: a mold body 100 and a cooling assembly 200; the mold body 100 includes an upper mold 101 and a lower mold 102 at its upper and lower ends; the cooling assembly 200 includes a movable plate 201 movably mounted on the top of the lower mold 102, a module 202 fixedly disposed in the middle of the movable plate 201, a mold cavity 203 disposed in the module 202, a side cooling port 204 disposed on the side of the module 202, a side cooling channel 205 fixedly installed in the side cooling port 204, a bottom cooling port 206 disposed at the bottom of the module 202, and a bottom cooling channel 207 fixedly installed in the bottom cooling port 206; the side cooling channel 205 is further provided with a side inlet 208 and a side cooling channel 207 at both ends. The outlet 209 and the bottom cooling channel 207 are respectively provided with bottom inlet 210 and bottom outlet 211 at both ends. The side inlet 208 and the bottom inlet 210 are also fixedly installed with inlet connecting sleeve 212. The inlet connecting sleeve 212 is also fixedly installed with inlet pipe 213. The side outlet 209 and the bottom outlet 211 are also fixedly installed with outlet connecting sleeve 214. The outlet connecting sleeve 214 is also fixedly installed with outlet pipe 215. The inlet connecting sleeve 212 and the outlet connecting sleeve 214 are both fixedly installed with partition 216. The movable plate 201 and the lower mold 102 are respectively provided with mounting holes 217 and threaded holes 218. The mounting holes 217 and the threaded holes 218 are also movably installed with screws 219.

[0028] Specifically, the set-top box mold is a manufacturing tool used to produce the plastic parts of the set-top box cover. The side cooling ports 204 and bottom cooling ports 206 on the side and bottom of the module 202 in the movable plate 201, with side cooling channels 205 and bottom cooling channels 207 installed within them, are located on the side and bottom of the mold cavity 203, respectively. This allows for simultaneous annular cooling of the side and bottom during cooling within the mold cavity 203, improving cooling uniformity. Simultaneously, the bottom cooling channel 207, with its curved shape, extends the cooling path and time. The movable plate 201 at the outer end of the module 202 is movably mounted to the upper part of the lower mold 102 via screws 219, facilitating the overall assembly and disassembly of the movable plate 201 for accessing the outer cooling channels 205 and bottom cooling channels 206 of the module 202. For convenient maintenance and repair, the water inlet connecting sleeve 212 installed at the outer end of the side water inlet 208 and the bottom water inlet 210, and the water outlet connecting sleeve 214 installed at the outer end of the side water outlet 209 and the bottom water outlet 211, allow the side cooling channel 205 and the bottom cooling channel 207 to share a set of water inlet pipe 213 and water outlet pipe 215, thereby increasing the convenience of drainage. At the same time, the baffle 216 in the water inlet connecting sleeve 212 can also divert the incoming cooling water to ensure that it is diverted to the side cooling channel 205 and the bottom cooling channel 207, while cooling the side and bottom of the mold cavity 203. The baffle 216 in the water outlet connecting sleeve 214 can also ensure that the water discharged from the side cooling channel 205 and the bottom cooling channel 207 flows into the water outlet pipe 215 for drainage.

[0029] Working principle and usage process of this utility model:

[0030] After the set-top box cover is injection molded in the mold cavity 203, the cooling water entering through the water inlet pipe 213 will enter the water inlet connecting sleeve 212. Within the water inlet connecting sleeve 212, the water will be diverted by the partition 216 to flow to the side water inlets 208 and the bottom water inlet 210 at the upper and lower ends, respectively. This allows the water to flow along the side cooling channels 205 and the bottom cooling channels 207, simultaneously providing uniform cooling to the sides and bottom of the mold cavity 203, thus improving the injection molding performance of the set-top box cover. After cooling, the coolant flowing in the side cooling channel 205 and bottom cooling channel 207 will flow to the side outlet 209 and bottom outlet 211, and then be discharged through the outlet connecting sleeve 214 and outlet pipe 215. At the same time, the movable plate 201 can also be easily removed by disassembling the screw 219 between it and the lower mold 102 for maintenance and repair of the side and bottom cooling channels 205 and bottom cooling channels 207 of the module 202.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
