DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figure 1 - Figure 6 The present invention provides a technical solution: a two-plate injection molding machine mold clamping system, including a movable mold plate 100, a fixed mold plate 101 is arranged on the left side of the movable mold plate 100, and cleaning and preheating mechanisms 200 are symmetrically arranged on the front and rear surfaces of the fixed mold plate 101 and the movable mold plate 100. The cleaning and preheating mechanisms 200 can be used to move the gas in the extrusion cylinder by using the piston plate 2023 during the mold clamping process, and the gas is blown out of the mold cavity on the surface of the fixed mold plate 101 at high pressure, and the impurities falling on the inner surface of the mold cavity are blown out of the mold cavity, thereby improving the injection quality of the subsequent mold clamping injection molded parts and reducing impurities. The impact on the quality of injection molding, at the same time, during the blowing process, the blown gas can be temperature-controlled, and the mold cavity can be further cooled or preheated. The cleaning and preheating mechanism 200 includes a movable stand 201, and the movable stand 201 supports the entire processing component 202. The processing component 202 is arranged inside the movable stand 201, and the processing component 202 blows the impurities falling in the mold cavity outward. The right end of the movable stand 201 is vertically provided with a telescopic cylinder 204, and the telescopic cylinder 204 can adjust the position of the piston plate 2023 in the cylinder;

[0034] The processing component 202 includes a heating cylinder 2021 and a cooling cylinder 2022 fixed inside the movable stand 201. The heating cylinder 2021 and the cooling cylinder 2022 can choose to cool the mold cavity or preheat the mold cavity with hot air according to the temperature requirement of the mold cavity on the surface of the fixed mold plate 101. The rear surfaces of the heating cylinder 2021 and the cooling cylinder 2022 are provided with a filtering blowing component 203 located outside the fixed mold plate 101. The heating cylinder 2021 and the cooling cylinder 2022 are respectively provided with a spiral heating pipe 2025 and a spiral cooling pipe 2024. The spiral heating tube 2025 and the spiral cooling tube 2024 can cool and heat the gas entering the cylinder, and the outer ends of the heating cylinder 2021 and the cooling cylinder 2022 are provided with piston plates 2023. The movement of the piston plates 2023 can change the space inside the cylinder, which is convenient for pumping or blowing. The processing component 202 also includes a piston rod 2026 fixed on the outer surface of the piston plate 2023. The circumferential surfaces of the two piston plates 2023 are in contact with the inner walls of the heating cylinder 2021 and the cooling cylinder 2022.

[0035] The filtering and blowing component 203 includes an exhaust pipe 2031 installed on the rear surface of the heating cylinder 2021 and the cooling cylinder 2022 to facilitate the exhaust of the processed gas in the cylinder.

[0036] In this embodiment, preferably, an inner rod is provided inside the telescopic cylinder 204 to drive the piston rod 2026 to move. The inner rod is connected to the piston rod 2026. As the inner rod moves, the piston rod 2026 can be driven to move, thereby driving the piston plate 2023 to move, changing the position of the piston plate 2023 in the cylinder, thereby changing the exhaust volume.

[0037] In this embodiment, preferably, the filter blowing component 203 also includes a processing cylinder 2032 embedded in the exhaust pipe 2031, and a flip motor 2036 is provided on the upper surface of the outer end of the exhaust pipe 2031. The flip motor 2036 can drive the exhaust filter 2035 to rotate. When the gas is sucked, the exhaust filter 2035 is located outside the exhaust pipe 2031, and the exhaust pipe 2031 is completely exposed. The gas sucked into the cylinder is processed by the primary filter 2033 and the secondary filter 2034, and then enters the cylinder for preheating or cooling. When the gas is discharged, the flip motor 2036 drives the exhaust filter 2 035 is relocated to the outside of the exhaust pipe 2031 to filter the exhausted gas, so that the exhausted clean gas acts on the mold cavity, blows out the impurities in the mold cavity to keep the mold cavity clean, and an exhaust filter 2035 is vertically arranged on the outer end of the exhaust pipe 2031, and a fixed lug 2037 is arranged on the upper surface of the exhaust filter 2035, and the output shaft of the flip motor 2036 is connected to the fixed lug 2037, and a primary filter 2033 and a secondary filter 2034 are arranged in sequence inside the processing cylinder 2032, and the primary filter 2033 and the secondary filter 2034 can filter and process the gas sucked into the cylinder.

[0038] In summary, when the injection molding machine opens the mold, the movable platen 100 moves outward, which drives the fixed top plate 2012 to move, and drives the telescopic cylinder 204 to move. When the telescopic cylinder 204 moves, the rod inside it drives the piston rod 2026 and the piston plate 2023 to move outward, increasing the space inside the heating cylinder 2021, and drawing the outside air into the exhaust pipe 2031. At this time, the exhaust filter 2035 is located on the outside of the exhaust pipe 2031, and the air passes through the primary filter 2033 and the secondary filter 2034 for filtering. The filtered clean air enters the heating cylinder 2021 and is heated by the spiral heating pipe 2025. When the movable platen 100 stops working, the piston plate 2023 stops moving. During the mold closing process of the injection molding machine, the movable platen 100 moves inward to close the mold, driving the telescopic cylinder 204 to move. The telescopic cylinder 204 moves, and the rod inside it pushes the piston rod 2026 and the piston plate 2023 to move inward, squeezing the space inside the heating cylinder 2021 and sending the gas inside the heating cylinder 2021 into the exhaust pipe 2031. At this time, the flip motor 2036 works, driving the exhaust filter 2035 to rotate to cover the end of the exhaust pipe 2031, so that the exhausted gas can be filtered. Impurities in the gas are retained on the exhaust filter 2035, and the clean gas can easily act on the surface of the mold cavity. The exhausted hot air passes through the exhaust filter 2035 and acts on the surface of the mold cavity on the surface of the fixed mold plate 101. The hot air can preheat the mold cavity, and the flowing hot air can blow away the impurities on the surface of the mold cavity, so that the surface of the mold cavity is relatively clean, reducing the impurities on the surface of the subsequent injection molded parts, and improving the injection molding quality of the injection molded parts.

[0039] Example 2

[0040] Reference Figure 3 and Figure 7 , which is the second embodiment of the present invention.

[0041] In this embodiment, preferably, the movable stand 201 includes a fixed bottom plate 2011 and a fixed top plate 2012 respectively fixed on the surfaces of the fixed template 101 and the movable template 100. By utilizing the mobility of the movable stand 201, the position of the filter blowing component 203 can be adjusted before the movable template 100 and the fixed template 101 are completely molded, so that the filter blowing component 203 is close to the position of the mold cavity, which is convenient for preheating and blowing treatment of the mold cavity surface without affecting the normal mold closing of the movable template 100 and the fixed template 101. A support plate 2019 is slidably provided on the inner side of the fixed bottom plate 2011 and the fixed top plate 2012, and a telescopic cylinder 204 is embedded in the support plate 2019 on the right side. A guide stand 2013 that movably penetrates the right support plate 2019 is vertically provided on the surface of the left support plate 2019, and the guide stand 2013 penetrates the right support plate 2 019, does not affect the movement of the movable template 100, and at the same time, the left support plate 2019 moves, which can drive the guide vertical plate 2013 and the right support plate 2019 to move synchronously. A moving cylinder 2014 is arranged on the inner surface of the fixed bottom plate 2011, and the moving cylinder 2014 can drive the left and right support plates 2019 to move synchronously. A fixed plate 2015 is arranged on the left end of the left support plate 2019, and a moving rod arranged inside the moving cylinder 2014 is connected to the fixed plate 2015. Two guide grooves 2017 are arranged on the left and right sides of the two support plates 2019, and fixed guide plates 2016 that slide with the guide grooves 2017 are arranged on the inner surfaces of the fixed top plate 2012 and the fixed bottom plate 2011, and the fixed guide plates 2016 slide with the guide grooves 2017, which neither affects the movement of the support plate 2019 nor supports the support plate 2019.

[0042] In this embodiment, preferably, the fixed top plate 2012 is L-shaped, and a rectangular notch 2018 for the telescopic cylinder 204 to pass through is opened on the surface of the fixed top plate 2012, so as to facilitate the telescopic cylinder 204 to move in the rectangular notch 2018.

[0043] In summary, after the mold is opened and the material is unloaded, the moving cylinder 2014 works, and the internal moving rod retracts, driving the fixed plate 2015 and the left support plate 2019 to move toward the movable template 100. Since the right support plate 2019 and the left support plate 2019 are connected by the guide vertical plate 2013, the two support plates 2019 move synchronously along the fixed guide plate 2016 toward the movable template 100, and the telescopic cylinders 204 and the processing components 202 arranged on the two support plates 2019 move toward the movable template 100 together, and the filter blowing component 20 3 moves toward the mold cavity on the surface of the movable mold plate 100, and after approaching the mold cavity, blows air toward the mold cavity and performs preheating treatment. Before the movable mold plate 100 and the fixed mold plate 101 are completely molded, the movable cylinder 2014 works again, and the internal moving rod moves the support plate 2019 outward along the fixed guide plate 2016, and the filtering blowing component 203 moves outward and is located outside the movable mold plate 100, which does not affect the normal mold closing of the movable mold plate 100 and the fixed mold plate 101. This arrangement can be close to the mold cavity, which is convenient for better blowing and cleaning of impurities on the surface of the mold cavity and preheating treatment.

[0044] Example 3

[0045] Reference Figure 5 and Figure 8 , which is the third embodiment of the present invention.

[0046] In this embodiment, preferably, an adjusting member 205 is provided between the telescopic cylinder 204 and the piston rod 2026. By using the adjusting member 205, the telescopic cylinder 204 can be selected to be connected with the piston rod 2026 inside the heating cylinder 2021 or the cooling cylinder 2022 according to the temperature requirement of the mold cavity on the surface of the fixed mold plate 101, thereby changing the temperature of the gas blown into the mold cavity, which can not only cool the mold cavity but also play a preheating role. The adjusting member 205 includes a fixing frame 2051 installed at the inner end of the telescopic cylinder 204 and inside the fixing frame 2051. An adjusting motor 2052 is embedded and provided, and the adjusting motor 2052 can rotate forward and reverse. An L-shaped pushing panel 2055 is connected to the inner end of the adjusting motor 2052. The pushing panel 2055 can adjust the position of the pushing panel 2055 as the adjusting motor 2052 rotates forward or reverse. A mounting block 2053 is provided at the outer end of the piston rod 2026. An embedding notch 2054 is provided on the surface of the mounting block 2053 for the pushing panel 2055 to extend into. The embedding notch 2054 is rectangular, and the cross-section of the pushing panel 2055 is rectangular.

[0047] In this embodiment, preferably, a plurality of mold closing positioning rods 103 are arranged between the movable mold plate 100 and the fixed mold plate 101, which can play a guiding and positioning role in the mold closing process of the two. A mold base 102 is arranged on the left side of the fixed mold plate 101, and a push rod is vertically arranged on the left side of the mold base 102.

[0048] In summary, when in use, the regulating motor 2052 works. When the regulating motor 2052 reverses, it can drive the pushing panel 2055 to rotate 180 degrees, so that the pushing panel 2055 is embedded in the embedding notch 2054 on the surface of the mounting block 2053. At this time, the pushing panel 2055 is connected to the piston rod 2026 inside the refrigeration cylinder 2022. As the movable template 100 moves, the piston rod 2026 inside the refrigeration cylinder 2022 can be pushed to move. The discharged gas is cooled gas, which is convenient for cooling the mold cavity. Conversely, the regulating motor 2052 rotates forward, driving the pushing panel 2055 to rotate 180 degrees and cooperate with the embedding notch 2054 on the surface of the upper mounting block 2053. At this time, the moving rod inside the telescopic cylinder 204 is connected to the piston rod 2026 inside the heating cylinder 2021. As the movable template 100 moves, the heated gas can be discharged, which is convenient for blowing air to preheat the mold cavity surface and expand the temperature processing range of the mold cavity.

[0050] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0051] When the injection molding machine is closing the mold, the adjusting component 205 is used to select the push panel 2055 to connect with the heating cylinder 2021 or the cooling cylinder 2022, and the movable stand 201 is used to change the position of the filtering blowing component 203 to make it away from or close to the fixed mold plate 101, and then the processing component 202 is used to blow out the refrigerated or preheated gas, which can not only cool or preheat the mold cavity, but also facilitate the gas to blow out impurities on the surface of the mold cavity, keep the mold cavity relatively clean, and improve the injection quality of the injection molding parts of the injection molding machine.
