Description

Technical Field

[0001] This utility model belongs to the field of protective structure technology, specifically relating to a protective structure for a plastic extrusion mold. Background Technology

[0002] Plastic extrusion molds, also called extrusion dies, extrusion molding heads, or die heads, are devices used to mold plastic parts. When installing and using plastic extrusion molds, they need to be protected. This is usually achieved by installing a protective structure on the outer surface of the plastic extrusion mold. The existing protective structures are used to protect the plastic extrusion mold during processing and production, making it easy to directly fix the plastic extrusion mold inside for molding and extrusion operations.

[0003] Existing protective structures for plastic extrusion molds involve fixing the mold inside and then closing the protective cover. Inside the main protective box, a cooling fan blows air through an air intake grille for ventilation and cooling. However, the air intake grille is located directly at the top. Prolonged air intake or disuse can cause dust to accumulate on its surface, making regular cleaning difficult and prone to clogging, thus reducing its cooling efficiency. This compromises the convenience of regularly cleaning the air intake grille when using the protective structure for plastic extrusion molds. Therefore, this invention proposes a new protective structure for plastic extrusion molds. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for plastic extrusion molds, in order to solve the problem that when the protective structure proposed in the background art is used to protect plastic extrusion molds, the air inlet mesh plate is directly at the top. When air is introduced for a long time or when it is not used, dust will easily fall on the surface of the air inlet mesh plate and adhere to the surface. It is also inconvenient to clean the air inlet mesh plate regularly, which can easily cause blockage and reduce the air intake and heat dissipation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a plastic extrusion mold, comprising a main protective structure body, the main protective structure body including a main protective box, a plastic extrusion mold body being mounted inside the main protective box via a fixing frame, a protective cover plate being closed and installed at the top of the main protective box, air inlet mesh plates being provided inside both ends of the protective cover plate, two cooling fans being fixed to the lower surface of the plastic extrusion mold body located on the inner bottom surface of the main protective box, and exhaust holes being provided at the bottom of both sides of the main protective box, and the protective structure body also being provided with:

[0006] A convenient cleaning mechanism, comprising sliding and detachable components disposed at the connection points between the air intake grille and the interior of the protective cover, wherein the end of the air intake grille is provided with a limiting component located on the side of the protective cover, and a cleaning component is provided on the surface of the limiting component;

[0007] The water-cooling mechanism includes a water storage component located at the bottom of the main protective box, a drainage component located at the middle of one side of the main protective box, and water-cooled heat dissipation components located at the ends of the drainage component on both sides of the main protective box.

[0008] Preferably, the sliding assembly includes grooves formed at both ends of the protective cover, and the air intake mesh is embedded inside the grooves. Sliding grooves are formed on both sides of the interior of the grooves, and sliding plates are provided on both sides of the air intake mesh.

[0009] Preferably, the slide plate is slidably connected to the interior of the trough, and one end of the trough is located on the upper surface of the protective cover plate with two fixing screws, and the slide plate and the protective cover plate are fixedly connected by the fixing screws.

[0010] Preferably, the limiting component includes limiting grooves formed on both sides of one end of the groove, a limiting connecting plate is limited inside the limiting groove, and an elastic plate is fixed at the connection between the lower surface of the limiting connecting plate and the bottom of the limiting groove.

[0011] Preferably, the cleaning component includes a cleaning brush fixed to the surface of the limiting connecting plate, and the surface of the cleaning brush is in contact with the surface of the air intake mesh plate.

[0012] Preferably, the water storage component includes a water storage tank formed at the bottom of the main protective box, and an inlet is provided on one side of the water storage tank.

[0013] Preferably, the drainage assembly includes a water pump fixed to the bottom of one side of the main protective box, a water outlet pipe provided on the front surface of the water pump, the water outlet pipe extending into the interior of the water storage tank, and a connecting pipe provided on the upper surface of the water pump.

[0014] Preferably, the water-cooled heat dissipation assembly includes water inlet channels opened inside both sides of the main protective box, the end of the connecting pipe is sealed and fixed to one end of the water inlet channel, a connecting pipe is installed at the end of the main protective box where the two water inlet channels are connected, and a return water pipe is installed at the connection between the other end of the water inlet channel and the interior of the water storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By designing a convenient cleaning mechanism, when the main body of the protective structure is in use and dust falls and adheres to the exposed top of the air intake grille on the air intake or placement surface, the handle at the hand end can be pulled to open the air intake grille. The deformation of the elastic plate causes the limiting connecting plate and the cleaning brush to be elastically pressed together, so that the cleaning brush is pressed tightly against the surface of the air intake grille. This facilitates the contact of the upper and lower surfaces of the air intake grille with the cleaning brush for cleaning, making it convenient to slide and clean the air intake grille regularly. The cleaning process is convenient, and the air intake heat dissipation is effectively treated, improving the convenience of regularly cleaning the air intake grille when the main body of the protective structure is used to protect the plastic extrusion mold body.

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.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a protective structure for a plastic extrusion mold, including a protective structure body 100, the protective structure body 100 including a main protective box 101, a plastic extrusion mold body 105 installed inside the main protective box 101 by a fixing frame, a protective cover plate 102 closed at the top of the main protective box 101, air inlet mesh plates 103 provided inside both ends of the protective cover plate 102, two cooling fans 106 fixed on the lower surface of the plastic extrusion mold body 105 located on the inner bottom surface of the main protective box 101, and exhaust holes 104 opened at the bottom of both sides of the main protective box 101. The protective structure body 100 is also provided with:

[0026] The convenient cleaning mechanism includes sliding and detachable components located at the connection points between the air intake grille 103 and the protective cover 102 on both sides. The end of the air intake grille 103 is provided with a limiting component on the side of the protective cover 102. The surface of the limiting component is provided with a cleaning component. During long-term protective use, when air enters the surface of the air intake grille 103 or dust falls and adheres to the surface, the convenient cleaning mechanism can slide and clean the air intake grille 103. The cleaning process is convenient and effectively improves air intake and heat dissipation.

[0027] To facilitate the sliding disassembly and cleaning of the air intake grille 103 using the sliding disassembly assembly, in this embodiment, preferably, the sliding disassembly assembly includes grooves 1031 formed at both ends of the protective cover 102, with the air intake grille 103 embedded inside the grooves 1031. Sliding grooves 1036 are formed on both sides of the interior of the grooves 1031, and sliding plates 1035 are provided on both sides of the air intake grille 103. The sliding plates 1035 can slide within the sliding grooves 1036 to adjust the air intake grille 103, facilitating the sliding disassembly and cleaning of the air intake grille 103. One end of the groove 1031 is located on the upper surface of the protective cover 102, where two fixing screws 1034 rotate. The sliding plate 1035 is fixedly connected to the protective cover 102 by the fixing screws 1034. After the air intake grille 103 is closed after sliding and cleaning, the fixing screws 1034 are rotated again to fix the sliding plate 1035 to the air intake grille 103.

[0028] In order to facilitate the limiting and elastic connection of the cleaning brush 1033 by means of the limiting component, in this embodiment, preferably, the limiting component includes limiting grooves 1037 formed on both sides of one end of the groove 1031. The limiting groove 1037 is internally limited by a limiting connecting plate 1032. An elastic plate 1038 is fixed at the connection between the lower surface of the limiting connecting plate 1032 and the bottom of the inner end of the limiting groove 1037. The elastic plate 1038 can be deformed to elastically connect the limiting connecting plate 1032 and the cleaning brush 1033, which facilitates elastic and tight cleaning treatment.

[0029] In order to facilitate the sliding cleaning of the surface of the air intake grille 103 by means of the cleaning component, in this embodiment, preferably, the cleaning component includes a cleaning brush 1033 fixed to the surface of the limiting connecting plate 1032, and the surface of the cleaning brush 1033 is in contact with the surface of the air intake grille 103. When the limiting connecting plate 1032 is elastically connected, it can drive the cleaning brush 1033 to be pressed tightly against the surface of the air intake grille 103, which facilitates the sliding cleaning of the air intake grille 103 and makes the cleaning process convenient.

[0030] The water-cooling mechanism includes a water storage component located at the bottom of the main protective box 101, a drainage component located at the middle of one side of the main protective box 101, and water-cooling heat dissipation components located at the ends of the drainage component on both sides of the main protective box 101. This allows the main protective structure 100 to be cooled by the cooling fan 106 while providing protection, and the water-cooling mechanism can then further cool the interior of the main protective box 101, thus accelerating the heat dissipation process.

[0031] In order to facilitate water storage and cooling through the water storage component, in this embodiment, preferably, the water storage component includes a water storage tank 1017 formed at the bottom of the main protective box 101. An inlet is provided on one side of the water storage tank 1017, through which water can be introduced into the water storage tank 1017 for storage and treatment.

[0032] In order to facilitate the internal water circulation and cooling treatment of the water inlet channel 1012 through the drainage assembly, in this embodiment, preferably, the drainage assembly includes a water pump 1015 fixed to the bottom of one side of the main protective box 101. The front surface of the water pump 1015 is provided with a water outlet pipe 1016, which extends into the interior of the water storage tank 1017. The upper surface of the water pump 1015 is provided with a connecting pipe 1014, which can draw water from the interior of the water storage tank 1017 through the water outlet pipe 1016 when the water pump 1015 is powered on and re-enter the interior of the connecting pipe 1014 for water inlet treatment.

[0033] To facilitate the circulating water cooling of the main protective box 101, in this embodiment, preferably, the water cooling system includes water inlet channels 1012 located inside both sides of the main protective box 101. The end of the connecting pipe 1014 is sealed and fixed to one end of the water inlet channel 1012. A connecting pipe 1011 is installed at the connection point of the two water inlet channels 1012 at the end of the main protective box 101. Water can enter the water inlet channel 1012 through the connecting pipe 1014 and then enter the water inlet channel 1012 on the other side of the main protective box 101 through the connecting pipe 1011, which facilitates the circulating water cooling of the main protective box 101. A return water pipe 1013 is installed at the connection point between the other end of the water inlet channel 1012 and the inside of the water storage tank 1017. Finally, the water entering the water inlet channel 1012 is returned to the inside of the water storage tank 1017 through the return water pipe 1013.

[0034] The water pump 1015 in this utility model is model ZX45D.

[0035] The working principle and usage process of this utility model are as follows: When using this protective structure for plastic extrusion mold, the main body 100 of the protective structure is placed stably in the usage position by directly contacting the bottom of the main protective box 101 with the operating position, and the plastic extrusion mold is fixed inside the main protective box 101. The protective cover plate 102 is fixedly closed on the top of the main protective box 101 for protection. When heat is generated inside the plastic extrusion mold body 105 during operation, the cooling fan 106 runs and the air intake mesh plate 103 introduces air into the main protective box 101 to form circulation. When blowing air, it is discharged through the exhaust hole 104, thereby facilitating heat dissipation during protection.

[0036] Then, while the main protective structure 100 is providing protection, it also cools the interior of the main protective box 101 through the cooling fan 106. Cooling water is then injected into the water storage tank 1017. The water pump 1015 can be powered on to draw water from the outlet pipe 1016 into the connecting pipe 1014. The water then enters the inlet channel 1012 through the connecting pipe 1014. After entering the inlet channel 1012, the water enters the inlet channel 1012 on the other side of the main protective box 101 through the connecting pipe 1011. Finally, the water flows back to the water storage tank 1017 through the return pipe 1013. This allows the cooling water to circulate in the inlet channel 1012 to cool the interior of the main protective box 101 again, and it also allows for water cooling when the cooling fan 106 blows air. This double cooling treatment makes the cooling effect more effective and improves the double cooling effect of the main protective structure 100 when protecting the plastic extrusion mold body 105.

[0037] Finally, before using the main body 100 of the protective structure, the air intake mesh 103 can be engaged with the slide plate 1035 inside the slide groove 1036 to engage with the inside of the groove 1031. Then, the fixing screws 1034 are rotated again to secure the air intake mesh 103. After installation, when the main body 100 of the protective structure is in use, if dust falls onto the air intake or placement surface and adheres to the exposed top of the air intake mesh 103, the protective cover 102 can be opened to remove the fixing screws 1034. The handle at the end can be used to pull the air intake mesh 103, and the slide plate 1035 will slide within the slide groove 1036 to engage the air intake mesh. When the plate 103 is pulled open, the deformation of the elastic plate 1038 causes the limiting connecting plate 1032 and the cleaning brush 1033 to be elastically pressed together, so that the cleaning brush 1033 is pressed tightly against the surface of the air intake mesh plate 103. This facilitates the contact of the cleaning brush 1033 with the upper and lower surfaces of the air intake mesh plate 103 for cleaning, and makes it convenient to regularly slide and clean the air intake mesh plate 103. The cleaning process is convenient, and the dust after cleaning slides to the side and falls to the ground, effectively improving the air intake and heat dissipation. This enhances the convenience of regularly cleaning the air intake mesh plate 103 when the protective structure body 100 is protected by the plastic extrusion mold body 105.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art 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 appended claims and their equivalents.
