Description

Technical Field

[0002] In industrial production and manufacturing, molds are widely used. Molds often need to be cooled while working, usually to maintain an appropriate working temperature to ensure product quality and production efficiency.

The corresponding cooling method should also be different, and the mold should be cooled evenly while cooling it to avoid excessive or large local stress of the product in the mold due to local differences in cooling, which affects product quality.

DETAILED DESCRIPTION

[0027] 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.

[0028] Embodiment 1:

[0029] See also Figure 1-5A mold cooling device comprises a main body 1, a water circulation heat dissipation mechanism, a mold operation mechanism and a spray mechanism, wherein the water circulation heat dissipation mechanism comprises a water tank 2, a first water pump 3, a water delivery pipe 4, a heat dissipation box 5 and a return water pipe 6, wherein the water tank 2 is fixedly mounted on the main body 1, the first water pump 3 is fixedly mounted on the water tank 2, the water delivery pipe 4 is fixedly connected to the output end of the first water pump 3, the heat dissipation box 5 is fixedly mounted on the main body 1, and is fixedly connected to one end of the water delivery pipe 4, and both ends of the return water pipe 6 are respectively fixedly connected to the water tank 2 and the heat dissipation box 5, the mold operation mechanism comprises a fixed mold 7, a movable mold 8, a cylinder 9 and a drawer 10, the fixed mold 7 is fixedly mounted on the main body 1, the movable mold 8 is mounted on the main body 1 and is slidably connected to the main body 1, the cylinder 9 is fixedly mounted on the main body 1 and the output end is fixedly connected to the movable mold 8, and the drawer 10 is mounted at the bottom of the main body 1 and is slidably connected to the main body 1.

[0030] In this embodiment, the water circulation heat dissipation mechanism includes a water tank 2, a first water pump 3, a water pipe 4, a heat dissipation box 5 and a return pipe 6. When in use, the first water pump 3 is driven to transfer the water in the heat dissipation cavity 15 of the water tank 2 from the water pipe 4 to the heat dissipation water pipe 29 in the heat dissipation box 5. When the heat dissipation liquid flows in the heat dissipation water pipe 29, it absorbs heat under the action of the connecting block 30 and the heat dissipation box 5, and then enters the water tank 2 through the return pipe 6. At this time, the temperature of the heat dissipation liquid rises. After entering the water tank 2, the heat dissipation rod 17 in the water tank 2 absorbs heat and transfers it to the heat dissipation plate 18, and then the heat dissipation plate 18 transfers it to the outside for heat exchange. At this time, a fan or other turbulent device can be set outside to quickly blow away the heat and improve the heat dissipation efficiency. When the heat is absorbed and dissipated, the temperature of the heat dissipation liquid at this time is stabilized, ready for the next heat dissipation process.

[0031] In this embodiment, the mold operation mechanism includes a fixed mold 7, a movable mold 8, a cylinder 9 and a drawer 10. When in use, the cylinder 9 drives the movable mold 8 to fit with the fixed mold 7. At this time, the external filler is added, and then after the above-mentioned cooling, the cylinder 9 returns. At this time, the spray mechanism is operated to spray the shaped model. The water droplets after spraying will carry impurities on the mold or the formed model into the recycling box 19, and the fallen model or burrs will remain in the drawer 10 and the upper layer of the recycling box 19 under the action of the filter net 20, and the water droplets will fall into the recycling box 19, completing the recycling of the model and water resources.

[0032] In this embodiment, the spray mechanism includes a second water pump 11, a water distribution pipe 12, a connecting hose 13 and a nozzle 14. When in use, when the mold injection is completed and the movable mold 8 is withdrawn, the second water pump 11 is driven to extract water from the spray chamber 16 and transmit it to the water distribution pipe 12 located in the water supply frame 21. Then the water distribution pipe 12 is again transmitted to the nozzle 14 installed in the hoop 24 through the connecting hose 13. As the distance of the movable mold 8 changes, the angle of the nozzle 14 should also change accordingly. At this time, the adjusting motor 25 on the adjusting frame 22 is driven to drive the lead screw 26 to rotate, so that the adjusting rod 28 moves up and down in the slide groove 27, and the nozzle 14 also begins to change its angle under the action of the hoop 24 and the baffle 23, so that the movable mold 8 is sprayed all over to cool it down.

[0033] Embodiment 2:

[0034] To sum up, when in use, first, the cylinder 9 drives the movable mold 8 to fit with the fixed mold 7. At this time, in the external filling and the mold fitting process, the first water pump 3 is driven to transfer the water in the heat dissipation cavity 15 of the water tank 2 from the water delivery pipe 4 to the heat dissipation water pipe 29 in the heat dissipation box 5. When the heat dissipation liquid flows in the heat dissipation water pipe 29, it absorbs heat under the action of the connecting block 30 and the heat dissipation box 5, and then enters the water tank 2 through the return pipe 6. At this time, the temperature of the heat dissipation liquid rises. After entering the water tank 2, the heat dissipation rod 17 in the water tank 2 absorbs heat and transfers it to the heat dissipation plate 18, and then the heat dissipation plate 18 transfers it to the outside for heat exchange. At this time, a fan or other turbulent device can be set outside to quickly blow away the heat to improve the heat dissipation efficiency. When the heat is absorbed and dissipated, the temperature of the heat dissipation liquid is stabilized and ready for the next heat dissipation process. Then, after the above-mentioned cooling, the cylinder 9 returns. At this time, the spray mechanism is running, and the second water pump 11 is driven The water is extracted from the spray chamber 16 and transmitted to the water distribution pipe 12 located in the water supply frame 21. Then the water distribution pipe 12 is transmitted to the nozzle 14 installed in the hoop 24 again through the connecting hose 13. As the distance of the movable mold 8 changes, the angle of the nozzle 14 should also change accordingly. At this time, the adjusting motor 25 on the adjusting frame 22 is driven to drive the lead screw 26 to rotate, so that the adjustment rod 28 moves up and down in the slide groove 27, and the nozzle 14 also begins to change its angle under the action of the hoop 24 and the baffle 23. At this point, the spray fully moves the mold 8 to cool it down. After the shaped model is sprayed and cooled, the water droplets after the spraying will carry the impurities on the mold or the formed model into the recycling box 19, and the fallen model or burrs, etc., are left in the drawer 10 and the upper layer of the recycling box 19 under the action of the filter net 20, and the water droplets fall into the recycling box 19, completing the recycling of the model and water resources.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
