Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PP box production equipment, specifically a molding cooling device for PP box production. Background Technology
[0002] In the production of PP boxes, molding cooling is a crucial step. Existing molding cooling devices for PP box production typically employ a single cooling method, such as relying solely on natural heat dissipation or simple water cooling structures. This results in low cooling efficiency, making it difficult to meet the demands of high-efficiency production. Furthermore, the heat dissipation treatment for the upper mold base is inadequate, with a simple heat dissipation structure leading to heat accumulation during operation. This not only affects molding quality but may also shorten the equipment's lifespan. Therefore, we propose a molding cooling device for PP box production. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3This utility model provides a technical solution: a molding and cooling device for PP box production, including a box body 1. An upper mold base 12 that can be raised and lowered is provided in the movable groove 11 at the top of the box body 1. A lower mold base 15 is provided inside the box body 1. A molding cavity 16 is opened at the top of the lower mold base 15. A heat-conducting plate 17 is provided on the outside of the lower mold base 15. A nozzle 18 is provided on the side of the heat-conducting plate 17. The nozzle 18 is connected to a water pump 19 through a pipe. The water pump 19 is connected to a water tank 21 through a connecting pipe 2. The water outlet on the side of the box body 1 is connected to the water tank 21 through a circulation pipe 22. A heat dissipation cavity 26 is opened inside the upper mold base 12. The heat dissipation cavity 26 contains metal fins 27 and a small turbulence plate 28. A fan 29 is provided above the heat dissipation cavity 26.
[0018] By setting up a heat-conducting plate 17, a nozzle 18, a water pump 19, a water tank 21, and a circulation pipe 22, a water circulation cooling system is formed. Cold water is drawn out by the water pump 19 and sprayed onto the heat-conducting plate 17 on the lower mold base 15 through the nozzle 18, thereby cooling the lower mold base 15. The water flow can also return to the water tank 21 through the circulation pipe 22 for recycling, solving the problems of insufficient water circulation and low cooling efficiency in traditional devices. The metal fins 27 and the baffle 28 in the heat dissipation cavity 26, together with the fan 29 above, form air cooling under the action of the fan 29, which effectively improves the heat dissipation effect of the upper mold base 12 and solves the problem of heat accumulation in the upper mold base.
[0019] In the above scheme, an extension plate 13 is provided at the end of the upper mold base 12, and a hydraulic cylinder 14 is provided below the extension plate 13. The extension plate 13 and the hydraulic cylinder 14 provide power and support for the lifting and lowering of the upper mold base 12, enabling the upper mold base 12 to lift and lower stably and reliably within the movable groove 11, facilitating its cooperation with the lower mold base 15 to complete the molding of the PP box, and solving the problem of insufficient stability in the lifting and lowering of the upper mold base.
[0020] In the above solution, a filter chamber 23 is connected to the circulation pipe 22, and a filter screen 24 is built into the filter chamber 23. The filter chamber 23 and the filter screen 24 can filter impurities in the circulating water, prevent impurities from clogging the nozzle 18 or the pipe, ensure the smooth flow of the water circulation system, extend the service life of the equipment, and solve the problem of easy clogging by impurities in traditional water circulation systems.
[0021] In the above scheme, a channel is provided above the heat dissipation cavity 26. The channel above the heat dissipation cavity 26 provides a passage for the fan 29 to draw in air and expel hot air, so that the air can form a good flow within the heat dissipation cavity 26. Together with the metal fins 27 and the baffle 28, the heat dissipation effect is further enhanced, and the problem of poor air circulation in the heat dissipation cavity is solved.
[0022] In the above scheme, the upper mold base 12 has a heat dissipation hole 3 on its side that communicates with the heat dissipation cavity 26. The setting of the heat dissipation hole 3 increases the contact area between the heat dissipation cavity 26 and the outside, making it easier for the heat inside the heat dissipation cavity to be dissipated to the outside. Together with the fan 29, metal fins 27 and baffle 28, it further improves the heat dissipation efficiency of the upper mold base 12 and solves the problem of insufficient heat dissipation of the upper mold base.
[0023] In the above scheme, a switch 25 is provided on the outside of the housing 1. The switch 25 is used to control the start and stop of the entire device, which facilitates the operator's control of the equipment and improves the ease of use of the equipment.
[0024] In the above solution, a temperature sensor is installed inside the lower mold base 15. The temperature sensor can monitor the temperature inside the lower mold base 15 in real time. Based on the information fed back by the temperature sensor, the operator can adjust the working status of equipment such as the water pump 19 and the fan 29 in a timely manner, so as to achieve precise control of the cooling process, ensure the molding quality of the PP box, and solve the problem that traditional devices cannot monitor the temperature in real time.
[0025] Working principle:
[0026] This molding and cooling device for PP box production operates by the operator starting the equipment via switch 25 on the outside of the housing 1. Hydraulic cylinder 14 then pushes extension plate 13, causing upper mold base 12 to descend within the movable groove 11 at the top of housing 1 until it engages with lower mold base 15, ready for PP box molding. PP material is placed into the molding cavity 16 at the top of lower mold base 15. After the upper mold base 12 descends, it closes with lower mold base 15, completing the PP box molding process within the cavity. During molding, water pump 19 starts, drawing cold water from water tank 21 through connecting pipe 2 and transporting it to nozzle 18. Nozzle 18 sprays the cold water onto heat-conducting plate 17 on the outside of lower mold base 15. Heat-conducting plate 17 transfers heat from lower mold base 15 to the cold water, thus cooling lower mold base 15 and molding cavity 16. The cooled water, carrying heat, flows out from the outlet on the side of the tank 1 and flows to the water tank 21 through the circulation pipe 22. When it flows through the filter chamber 23 on the circulation pipe 22, the filter screen 24 filters out impurities in the water, and the clean water flows back to the water tank 21, completing the water circulation cooling process. Inside the heat dissipation cavity 26 inside the upper mold base 12, the fan 29 starts and draws in outside air through the channel above the heat dissipation cavity 26. When the air flows in the heat dissipation cavity, it comes into contact with the metal fins 27 and the baffle 28. The metal fins 27 can increase the heat dissipation area and accelerate the dissipation of heat, while the baffle 28 can disrupt the air flow, so that the air can fully contact the metal fins 27 and improve the heat dissipation efficiency. The hot air after heat dissipation is discharged through the heat dissipation holes 3 on the side of the upper mold base 12 to achieve air cooling of the upper mold base 12; the temperature sensor in the lower mold base 15 monitors the temperature of the lower mold base in real time and transmits the temperature signal to the control system (not shown in the figure). The operator or the control system can adjust the flow rate of the water pump 19, the speed of the fan 29, etc. according to the temperature to adapt to different production needs, ensure that the molding process is carried out at a suitable temperature, and ensure the molding quality of the PP box.
