Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an intelligent injection molding machine. Background Art

[0002] Injection molding machines play an important role in many fields. In the field of automobile manufacturing, they are used to produce automobile interiors, bumpers, dashboards and other parts, helping the automobile industry to improve product quality and production efficiency. The electronics and electrical industry is also inseparable from injection molding machines. Mobile phone cases, computer keyboards, electrical appliance cases and other products are manufactured by them, providing support for the diversification and refinement of electronic and electrical products. In daily life, injection molding machines are a powerful tool for producing plastic tableware, toys, stationery and other supplies, meeting people's various daily consumption needs. It can be said that the widespread application of injection molding machines has promoted the development of various industries and is an indispensable and important equipment in modern industrial production. It plays an irreplaceable role in improving production efficiency, ensuring product quality and enriching product variety.

[0003] Traditional injection molding machines mainly rely on mechanical ejectors and other methods to separate products from molds. Although this method can meet the demoulding requirements of most conventional plastic products to a certain extent, mechanical ejectors often have limitations for some products with special shapes, complex structures, or products with extremely high surface quality requirements. For example, when producing plastic products with thin walls, undercuts, fine textures, or high-precision dimensions, mechanical ejectors may cause ejection marks, deformation, or even damage to the surface of the products, seriously affecting the quality and appearance of the products. In addition, the demoulding method of mechanical ejectors is usually point contact or local force, which makes it difficult to achieve uniform ejection force distribution. This is more likely to cause demoulding problems for large or asymmetric plastic products, reducing production efficiency and yield rate.

[0004] During the mold closing process, a certain amount of air will inevitably remain inside the mold. As the injection molding machine closes the mold, if these gases cannot be discharged or collected in a timely and effective manner, they will have many negative effects on the injection molding process and product quality. When the plastic melt is injected into the mold cavity, the gas in the cavity is squeezed, and quality problems such as internal defects seriously affect the strength, sealing and appearance of the product. At the same time, the presence of gas will hinder the uniform filling of the plastic melt, making the melt flow unstable, thereby producing molding defects such as weld marks and short shots, reducing the mechanical properties and dimensional accuracy of the product. In addition, the compression of gas during mold closing will cause the pressure in the mold cavity to increase, increasing the risk of mold wear and deformation, shortening the service life of the mold, and increasing production costs.

[0005] Therefore, an intelligent injection molding machine is proposed. Summary of the invention

[0037] 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.

[0038] See also Figures 1 to 9 , the present invention provides a technical solution for an intelligent injection molding machine:

[0039] An intelligent injection molding machine comprises an injection molding machine base 1 and a cabinet 2, a heat exchanger 3 and a controller 4 placed on the injection molding machine base 1, a heating mechanism 6 for heating feed is arranged on one side of the injection molding machine base 1, and a feed hopper 5 for feeding is fixedly connected to the heating mechanism 6, the heating mechanism 6 comprises a fixed base 62 and a rotating motor 61 fixed to one end of the fixed base 62, and a heating pipe 63 for heating plastic is fixedly connected to the other end of the fixed base 62, and an injection molding gun 65 for injection molding is fixedly connected to the end of the heating pipe 63, a demoulding mechanism 8 for mold closing and demoulding is fixedly connected to the other side of the injection molding machine base 1, and a mold mechanism 9 is installed inside the demoulding mechanism 8, a protective shell 66 for preventing staff from contacting is arranged on the outer side of the injection molding gun 65, and a preheating component 64 for heat preservation and preheating is arranged at the front end of the injection molding gun 65, so that the plastic will not solidify and block the injection molding gun 65 during injection molding;

[0040] During operation, the plastic raw material enters the heating mechanism 6 from the feed hopper 5, and the rotating motor 61 is started to drive the screw in the heating pipe 63 to rotate, thereby pushing the raw material to be transported forward in the heating pipe 63. During the transportation process, the heating pipe 63 heats the raw material. The heating principle can be heating by resistance wire or other heating methods (such as hot oil circulation, etc., which can be selected according to actual conditions) to heat the plastic raw material to a molten state suitable for injection molding. The injection molding gun 65 at the end of the heating pipe 63 injects the molten plastic into the mold mechanism 9 at a suitable pressure and speed under the control of the controller 4. The protective shell 66 on the outside of the injection molding gun 65 effectively prevents the staff from accidentally contacting the high-temperature injection molding gun to avoid safety accidents such as burns. The preheating component 64 at the front end (the preheating method can be electric heating or heat conduction, etc.) continuously maintains the temperature of the plastic in the injection molding gun to prevent the injection molding gun from solidifying and clogging the injection molding gun due to the decrease in plastic temperature during the injection molding process, thereby ensuring the continuity of the injection molding process.

[0041] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the mold mechanism 9 includes a fixed plate 1 91 and a fixed plate 2 93. The fixed plate 1 91 is provided with an injection port 92 that matches the injection gun 65. The fixed plate 1 91 is also fixedly connected to a fixed mold 95, and the fixed plate 1 91 is fixedly connected to the fixed mold platform 87 so that the injection gun 65 can inject plastic into the fixed mold 95. The upper and lower ends of the fixed plate 2 93 are fixedly connected to limit plates 94, and the limit plates 94 are fixedly connected to fixed rods 97, and the fixed rods 97 are movably connected to movable rods. The mold 96, and the movable mold 96 and the fixed plate 93 are also movably connected with a support plate 98 and a support rod plate 99, so that the movable mold 96 and the fixed rod 97 are separated during demoulding, and a plurality of pressure springs 910 are arranged on the support rod plate 99, and the pressure springs 910 are fixedly connected between the support plate 98 and the movable mold 96 to reduce the elastic potential energy during mold closing, and a damping plate 911 for damping is also arranged between the movable mold 96 and the support plate 98, and a circulation mechanism 10 is arranged inside the mold mechanism 9;

[0042] During operation, the injection port 92 precisely opened on the fixed plate 91 is precisely docked with the injection gun 65 to ensure that the plastic can be smoothly injected into the mold cavity. When the injection gun 65 injects the molten plastic into the fixed mold 95, the movable mold 96 is smoothly closed with the fixed mold 95 along the guidance of the fixed rod 97 (the fixed rod 97 plays the role of positioning and guiding the movement of the movable mold 96) under the clamping force applied by the demolding mechanism 8. The two are closely matched to form a complete cavity to accommodate the plastic melt during the injection molding process. During the clamping process, the multiple pressure springs 910 on the support rod plate 99 are gradually compressed to store a certain amount of elastic potential energy. This part of the elastic potential energy will be released during demolding, which is helpful for the separation of the movable mold 96 and the product 11. At the same time, the movable mold 96 and the support rod plate 99 are compressed gradually to store a certain amount of elastic potential energy. The damping plate 911 arranged between the plates 98 plays a damping and buffering role. The damping plate 911 can be made of rubber, hydraulic damper or other damping materials. Through its internal structure (such as rubber deformation, oil flow of hydraulic damper, etc.), it consumes the impact energy generated during mold closing, reduces vibration and noise during mold closing, ensures the stability and accuracy of mold closing, and thus improves the molding quality of the product. During demolding, the structural relationship between the movable mold 96 and the fixed plate 93 changes (due to the action of the demolding mechanism 8 or the coordinated action of other related components), so that the movable mold 96 overcomes the elastic force of the pressure spring 910 and other possible resistances such as friction, and separates from the fixed rod 97, thereby realizing the separation of the product 11 from the mold.

[0043] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the circulation mechanism 10 includes a collecting pipe 101 fixed on the damping plate 911, and four collecting pipes 102 for collecting gas are fixedly connected to the collecting pipe 101, a valve port 104 is fixedly connected to the front end of the collecting pipe 102, and a check valve 103 is also arranged inside the collecting pipe 102 near the front end to allow the gas to be sucked in one direction, the inside of the collecting pipe 101 is fixedly connected to a piston plate 107 through a spring 106, and the top of the collecting pipe 101 is fixedly connected to There are four air outlet pipes 108, so that when the gas pushes the piston plate 107 to the end of the collecting pipe 101, it is blown out through the air outlet pipes 108. The air outlet pipe 108 is fixedly connected to the live pipe 109 through the spring 110, and the live pipe 109 is movably connected to the inside of the damping plate 911. The inside of the live pipe 109 is movably connected to the piston tube 111, and the inside of the piston tube 111 is movably connected to the piston ball 118, so that when the gas enters the damping plate 911, the live pipe 109, the piston tube 111 and the air outlet pipe 108 are pushed out. The air pipe 108 is pushed out in sequence, the end of the piston tube 111 is fixedly connected with a nozzle 116, and the interior of the nozzle 116 is fixedly connected with a spring 119 for rebounding the piston ball 118, a plurality of air holes are opened around the piston ball 118, and the nozzle 116 is also provided with a plurality of nozzles 117 for uniformly spraying gas, so that the product 11 can be demoulded by gas, and the front end of the valve port 104 is fixedly connected with a semi-permeable membrane 105 for preventing plastic from flowing in, and The collecting tube 101 and the piston plate 107 fit tightly together, the outer side of the piston tube 111 is fixedly connected to a limiting ring 112, and the interior of the active tube 109 is provided with a sliding groove 113 matching the limiting ring 112, and the end of the active tube 109 is provided with a release agent airbag 114 so that the limiting ring 112 can squeeze the release agent airbag 114 after demolding, and the end of the active tube 109 is also provided with an agent outlet 115 so that the release agent can be sprayed out from the agent outlet 115 after the release agent airbag 114 is squeezed.

[0044] During operation, during the mold closing process, the air originally existing in the mold cavity and the gas brought in by the plastic melt during the injection molding process, driven by the pressure change inside the mold cavity, enter the gas collecting pipe 102 through the valve port 104 at the front end of the gas collecting pipe 102. The design of the valve port 104 ensures that the gas can smoothly enter the gas collecting pipe 102. At the same time, the semipermeable membrane 105 fixedly connected to the front end plays a key role in preventing the inflow of plastic. The semipermeable membrane 105 can be made of a special polymer material, and its pore size allows gas molecules to pass through, but prevents the entry of larger molecules in the plastic melt, effectively preventing the plastic from clogging the gas collecting pipe 102 during the gas collection process. The one-way valve 103 arranged inside the gas collecting pipe 102 near the front end ensures that the gas The gas collecting pipe 102 can only be sucked in one direction to prevent gas backflow. As the gas continues to enter the gas collecting pipe 102, the gas pressure in the collecting pipe 101 gradually increases, and the piston plate 107 overcomes the elastic force of the spring 106 under the action of the gas pressure and moves toward the end of the collecting pipe 101. The spring 106 plays a role of buffering and resetting, ensuring that the piston plate 107 can move smoothly when the gas pressure changes. When the piston plate 107 moves to the end of the collecting pipe 101, the gas in the collecting pipe 101 is blown out through the four gas outlet pipes 108 fixedly connected to the top. At this time, the blown gas has a certain pressure and speed, which pushes the live pipe 109 to overcome the elastic force of the spring 110 and move outward in the damping plate 911. The spring 110 also plays a role of buffering and resetting, ensuring that the piston plate 107 can move smoothly when the gas pressure changes. The piston tube 111 movably connected to the live tube 109 and the air jet head 116 connected to the piston tube 111 also move outward accordingly. When the air jet head 116 reaches a suitable position, the gas enters the piston tube 111 through multiple air holes opened around the piston ball 118. The piston ball 118 controls the flow direction and flow of the gas. It maintains dynamic balance under the joint action of the gas pressure and the spring 119. After the gas enters the piston tube 111, it is evenly ejected from the multiple nozzles 117 carefully designed on the air jet head 116, ensuring that the ejected gas can evenly act on the surface of the product 11, generating sufficient demoulding force to eject the product 11. The mold is blown out from the mold. After demolding, the limiting ring 112 fixedly connected to the outside of the piston tube 111 is guided by the limiting groove 113 opened in the active tube 109. As the piston tube 111 returns, it squeezes the mold release agent balloon 114 at the end of the active tube 109. The mold release agent balloon 114 stores a proper amount of mold release agent in advance (the type of mold release agent can be selected according to the actual product and mold material, such as silicone oil, wax, etc.). When squeezed, the mold release agent is sprayed out from the agent outlet 115 opened at the end of the active tube 109 and is evenly coated on the mold surface. The coating of the mold release agent reduces the friction between the product 11 and the mold, which is convenient for the next injection molding demolding process. At the same time, it can also protect the mold surface and extend the service life of the mold.

[0045] As an embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, a protective mechanism 7 for protecting the staff is also provided on the injection molding machine base 1, and the protective mechanism 7 includes a cabin guard plate 71 fixedly connected to the injection molding machine base 1, and cabin doors 72 are movably connected to both sides of the cabin guard plate 71, and handles 73 for moving the cabin doors 72 are fixedly connected to the cabin doors 72, and the demoulding mechanism 8 includes a transmission base 81 fixed to the injection molding machine base 1 and a hydraulic rod 82 fixed to the end of the transmission base 81, and a transmission rod 1 83 and a transmission rod 2 84 are movably connected inside the transmission base 81, and a movable plate 85 is movably connected to the transmission rod 1 83 and the transmission rod 2 84, and the movable plate 85 is fixedly connected to the output shaft of the hydraulic rod 82, and a fixed mold table 87 is also fixedly connected to one side of the transmission base 81, and a movable mold table 86 is movably connected to the other end of the transmission rod 2 84, and the movable mold table 86 is movably connected to the transmission base 81, so that when the hydraulic rod 82 is started, the movable mold table 86 is driven to slide on the transmission base 81.

[0046] During operation, the staff can conveniently open or close the cabin door 72 of the protection mechanism 7 by pulling the handle 73 on the cabin door 72. The cabin guard plate 71 is made of solid metal material or other high-strength material, which effectively isolates the working area of ​​the injection molding machine from the outside world, prevents the staff from accidentally entering the dangerous area when the injection molding machine is working, and avoids being injured by the operating parts of the injection molding machine (such as transmission parts, mold closing and demolding parts, etc.), providing reliable safety protection for the staff. When demolding is required, the demolding mechanism 8 starts to work, and the transmission base 81 fixed on the injection molding machine base 1 provides a stable support and installation foundation for the entire demolding mechanism. The hydraulic rod 82 fixed at the end of the transmission base 81 is started under the control of the controller 4 controlling the hydraulic system, and its output shaft produces The movable plate 85 generates linear motion, driving the movable plate 85 fixedly connected thereto to move smoothly along a specific guide rail (a guide rail structure is provided in the transmission base 81). The movement of the movable plate 85 is converted into a horizontal sliding motion of the movable die table 86 through the linkage action of the transmission rod 1 83 and the transmission rod 2 84 movably connected thereto by the hydraulic rod 82. The sliding process of the movable die table 86 on the transmission base 81 is smooth and accurate. The opening and closing action of the mold is realized through the relative movement between the movable die table 86 and the fixed die table 87, thereby completing the demoulding process. The fixed die table 87 is firmly fixed on one side of the transmission base 81, providing stable and accurate support for the fixed die 95, ensuring that the position of the fixed die 95 remains unchanged during the entire injection molding and demoulding process, and ensuring the precision and quality of product molding.

[0047] Working principle: During operation, the plastic raw material enters the heating mechanism 6 from the feed hopper 5, the rotating motor 61 is started, driving the screw in the heating pipe 63 to rotate, pushing the raw material forward in the heating pipe 63, and the heating pipe 63 heats the raw material by means of resistance wire heating or hot oil circulation, so that it reaches a molten state suitable for injection molding. The heated plastic is injected into the mold mechanism 9 by the injection gun 65 at a suitable pressure and speed under the control of the controller 4. The outer protective shell 66 of the injection gun 65 prevents people from being scalded, and the front preheating component 64 maintains the temperature of the plastic to prevent it from solidifying and clogging. In the mold mechanism 9, the injection port 92 of the fixed plate 91 is precisely docked with the injection gun 65;

[0048] When the injection gun 65 injects the molten plastic, the movable mold 96 is guided by the fixed rod 97 and closed with the fixed mold 95 under the clamping force of the demoulding mechanism 8 to form a cavity to accommodate the plastic melt. When the mold is closed, the pressure spring 910 on the support rod plate 99 is compressed to store elastic potential energy, and the damping plate 911 (such as rubber or hydraulic damper material) consumes impact energy, reduces vibration noise, ensures stable and accurate mold closing, and improves the molding quality of the product;

[0049] During the mold closing process, the original air in the mold cavity and the gas brought in by injection molding enter the gas collecting pipe 102 through the valve port 104 at the front end of the gas collecting pipe 102 under the drive of the cavity pressure change. The valve port 104 ensures that the gas enters smoothly. The front semi-permeable membrane 105 (special polymer material, allowing gas molecules to pass through and preventing plastic macromolecules from entering) prevents plastic from flowing into and blocking the gas collecting pipe 102. The one-way valve 103 in the gas collecting pipe 102 ensures one-way gas inhalation. The continuous entry of gas increases the air pressure in the collecting pipe 101, and the piston plate 107 overcomes the elastic force of the spring 106 and moves toward the end of the collecting pipe 101. The spring 106 plays a buffering and resetting role.

[0050] When the piston plate 107 moves to the end of the collecting tube 101, the gas is blown out through the gas outlet pipe 108, pushing the live tube 109 to overcome the elastic force of the spring second 110 and move outward in the damping plate 911. The spring second 110 ensures that the live tube 109 moves smoothly and can be restored. The piston tube 111 and the nozzle head 116 in the live tube 109 move outward accordingly. When the nozzle head 116 reaches the appropriate position, the gas enters the piston tube 111 through the air hole of the piston ball 118. The piston ball 118 controls the gas under the combined action of the gas pressure and the spring three 119. The gas is uniformly ejected from the nozzle 117 of the nozzle head 116 to generate sufficient demoulding force to blow the product 11 out of the mold. After demoulding, the outer limiting ring 112 of the piston tube 111 is limited by the sliding groove 113 of the active tube 109, and the demoulding agent airbag 114 at the end of the active tube 109 is squeezed with the return of the piston tube 111, so that the demoulding agent (such as silicone oil, wax, etc.) is ejected from the agent outlet 115 to coat the mold surface, thereby reducing the friction between the product 11 and the mold, facilitating the next demoulding, protecting the mold surface, and extending the mold life.

[0051] The staff opens or closes the cabin door 72 of the protective mechanism 7 by pulling the handle 73 of the cabin door 72. The cabin guard plate 71 (solid metal or high-strength material) isolates the working area to prevent personnel from accidentally entering the danger zone and being injured. During demolding, the hydraulic rod 82 in the demolding mechanism 8 is started under the control of the controller 4, and the linear motion of the output shaft drives the movable plate 85 to move smoothly along the guide rail in the transmission base 81. The movable plate 85 is linked by the transmission rod 1 83 and the transmission rod 2 84 to convert the linear motion of the hydraulic rod 82 into the horizontal sliding motion of the movable mold table 86. The movable mold table 86 and the fixed mold table 87 move relative to each other to realize the opening and closing of the mold, completing the demolding process. The fixed mold table 87 provides stable and accurate support for the fixed mold 95 to ensure the molding accuracy and quality of the product.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
