DETAILED DESCRIPTION

[0054] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0055] Embodiment 1

[0056] See also Figure 1 - Figure 5 , the present application provides a HP-RTM molding device, comprising:

[0057] A molding device 100 is installed on a base 102. A high-pressure injection molding machine head 101 is arranged on the right side of the molding device 100. A material unloading robot arm 103 is arranged in front of the molding device 100. The material unloading robot arm 103 can transfer the molded workpiece to a conveying device 104.

[0058] The mixing acceleration structure 200 installed between the molding equipment 100 and the high-pressure injection molding head 101 can be used to fully mix a variety of materials, and the mixed materials can be pressurized and pushed to a certain extent, so that the mixed materials can maintain a sufficient flow rate into the mold cavity, so that the mixed materials can fully fill the mold cavity and reduce factors affecting the molding quality of the materials. The mixing acceleration structure 200 includes a mixing box 201, an accelerating mixing component 205 for accelerating the mixing of resin entering the mixing box 201, an injection pipe 202 for injecting the mixed resin into the molding equipment 100, and two material pipes 207 connecting the mixing box 201 and the high-pressure injection molding head 101. The number of material pipes 207 can be set according to the type of mixing. The injection pipe 202 is stepped, and the diameter of the end close to the mold cavity is smaller, which is convenient for pressurization.

[0059] In this embodiment, preferably, a conical mixing channel 206 is opened inside the mixing box 201, and the cone has a pressurizing effect on the mixed material discharged from the left end. One end of the injection pipe 202 is connected to the small diameter end of the mixing channel 206, and the other end of the mixing channel 206 is connected to two material pipes 207, which facilitates the material to enter the mixing channel 206 through the material pipes 207. Support frames 204 are arranged on the front and rear surfaces of the mixing box 201.

[0060] In this embodiment, preferably, the accelerating mixing component 205 for mixing the resin material inside the mixing box 201 includes:

[0061] A push plate 2051 is vertically located on the inner side of the right end of the mixing box 201, the push plate 2051 is attached to the inner wall of the mixing channel 206, and the left end of the material pipe 207 passes through the mixing box 201 and the push plate 2051 and is located in the mixing channel 206;

[0062] A sealed telescopic tube 2053 is sleeved on the material pipe 207 and is located on the right side of the push plate 2051 and the right inner wall of the mixing box 201. The sealed telescopic tube 2053 does not affect the movement of the push plate 2051 and can prevent the material from entering the space between the right side of the push plate 2051 and the right inner wall of the mixing box 201.

[0063] A driving cylinder 2052 for driving the push plate 2051 to move;

[0064] A plurality of mixing rods 2055 are vertically installed in and sleeved on the mixing channel 206, and the mixing rods 2055 above and below the central axis of the mixing channel 206 are relatively distributed, so that when the mixing shaft 2054 rotates, the relatively distributed mixing rods 2055 thereon tend to relatively mix the materials, which facilitates the full mixing of the materials and discharges the mixed materials through the left end of the mixing channel 206.

[0065] In this embodiment, preferably, the front and rear inner walls of the mixing channel 206 are provided with a guide plate 2056 located on the left side of the push plate 2051 , and the piston rod inside the driving cylinder 2052 is connected to the right side of the push plate 2051 .

[0066] In this embodiment, preferably, a rotating member 208 is provided between the piston rod inside the driving cylinder 2052 and the upper end of the mixing shaft 2054. The rotating member 208 drives the mixing shaft 2054 to rotate synchronously with the movement of the pushing plate 2051, so as to further mix the materials entering the mixing channel 206. The rotating member 208 includes:

[0067] An outer gear 2082 is sleeved on the upper end of the mixing shaft 2054. A sealing bearing 2081 is embedded between the mixing shaft 2054 and the mixing box 201, which does not affect the rotation of the mixing shaft 2054 and can also play a sealing role;

[0068] The movable rack 2083 is located at the rear side of the outer gear 2082, and a guide seat 2084 for guiding the movable rack 2083 is arranged on the upper surface of the mixing box 201. The right end of the movable rack 2083 is connected to the vertical plate 2057 sleeved on the piston rod, and the vertical plate 2057 can move synchronously with the piston rod.

[0069] In summary, the high-pressure injection molding head 101 injects the material into the mixing channel 206, and the material flows to the left along the mixing channel 206, and flows along the guide plate 2056 close to the mixing shaft 2054. At the same time, the drive cylinder 2052 works, and the internal piston rod extends to drive the push plate 2051 to move to the left, and the sealing telescopic tube 2053 gradually expands, and the push plate 2051 moves, so that the space of the mixing channel 206 on the left becomes smaller, which has a certain densification effect on the mixing. At the same time, the material is pushed to move to the left, which has a certain pressurization and acceleration effect on the flow of the material, and makes up for the deceleration caused by the mixing. At the same time, the piston rod moves, and drives the vertical plate 2057 to move to the left, and the movement of the vertical plate 2057 drives the moving rack 2083 to move to the left. The outer gear 2082 meshing with the moving rack 2083 rotates, driving the mixing shaft 2054 and the mixing rod 2055 to rotate, fully mixing the passing materials and extending the mixing process. The movement of the push plate 2051 can supplement the resistance buffering caused by the mixing of the materials, so that the materials can still maintain a high flow rate and pressure after mixing, and are mixed more fully with each other. The mixed materials flow into the injection pipe 202 from the left end of the mixing channel 206, and the temperature consumed by the previous mixing is supplemented by the heating component 203. Finally, the materials are injected into the molding equipment 100 for processing. The whole process ensures that the materials are mixed fully, and can supplement the flow rate and pressure of the mixing, increase the density of the mixing, supplement the heat loss caused by the mixing, and improve the molding quality of the materials.

[0070] Embodiment 2

[0071] Reference Figure 6 , which is the second embodiment of the present invention.

[0072] In this embodiment, preferably, by providing a heating component 203, the mixed resin injected at the front end can be heated and kept warm, the injection molding temperature of the mixed resin can be maintained, and the heat loss can be reduced, thereby reducing the impact of the molding quality caused by the heat loss and improving the molding quality of the workpiece. The heating component 203 for keeping the injection pipe 202 warm includes:

[0073] A heat-insulating sleeve 2031 is sleeved on the injection pipe 202, and a vacuum chamber 2032 is provided inside the heat-insulating sleeve 2031 to play a role of heat insulation;

[0074] A plurality of heating rods 2034 vertically penetrate the heat-insulating sleeve 2031 and extend into the injection pipe 202. The plurality of heating rods 2034 have different heights, so as to be conveniently adapted to the cylindrical shape of the injection pipe 202 and to be conveniently distributed in the space of the injection pipe 202, so that the mixed resin passing through can fully contact the heating rods 2034.

[0075] And a connecting terminal 2033 installed on the upper surface of the insulation sleeve 2031 and connected to the heating rod 2034. The heating rod 2034 includes a heat-conducting outer shell and an internal heating rod, which heats the resin passing through without being affected by the resin temperature.

[0076] In summary, the plurality of heating rods 2034 are irregularly distributed in the injection tube 202. The temperature of the heating rods 2034 is utilized so that the mixed resin entering the injection tube 202 can fully contact the plurality of heating rods 2034. The temperature of the heating rods 2034 is transferred to the mixed resin, replenishing the heat lost during the flow of the mixed resin, maintaining the temperature of the mixed resin injected into the mold cavity, and improving the molding quality of the workpiece.

[0077] Embodiment 3

[0078] Reference Figure 7 - Fig.11 , which is the third embodiment of the present invention.

[0079] In this embodiment, preferably, a conveying device 104 is provided in front of the molding device 100, and a trimming and forming structure 300 for trimming and forming the workpiece falling thereon is provided on the top of the conveying device 104. The trimming and forming structure 300 can be used to perform subsequent trimming and forming on the edge of the workpiece separated from the molding device 100, so that the edge of the collected workpiece is flat, and the workpiece and the trimming waste are separated at the same time, thereby reducing the trouble of subsequent trimming and forming of the workpiece separately, and improving the workpiece forming processing efficiency. The trimming and forming structure 300 includes:

[0080] A stand 301 fixed to the top of the conveying device 104;

[0081] A trimming member 302 mounted on the upper end of the stand 301 for trimming the workpiece;

[0082] And a waste collecting member 303 for collecting the waste of the trimming.

[0083] In this embodiment, preferably, the trimming member 302 includes:

[0084] A lifting cylinder 3021 is vertically fixed on the upper surface of the stand 301, and a piston rod arranged inside the lifting cylinder 3021 is connected to the top frame;

[0085] The trimming tool holder 3022 is installed at the bottom of the top frame, and the two are connected by screws, which is convenient for replacing the appropriate trimming tool holder 3022 according to the shape of the workpiece, and the front and rear end surfaces of the trimming tool holder 3022 are provided with vertical blades to prevent the cut waste edges from being connected together.

[0086] In this embodiment, preferably, a plurality of adsorption components 304 are arranged on the side of the trimming component 302. When the trimming tool holder 3022 cuts the edge of the workpiece, the plurality of adsorption components 304 can simultaneously press and adsorb the trimming, and the trimming waste is synchronously adsorbed upward and separated from the workpiece along with the trimming tool holder 3022. The adsorption components 304 include:

[0087] A fixing seat 3041 is installed on the surface of the trimming member 302, and a guide column 3042 is vertically arranged inside the fixing seat 3041;

[0088] An elastic adsorption cylinder 3043 is installed at the lower end of the guide column 3042, and a fixing ear 3044 is provided on the upper surface of the elastic adsorption cylinder 3043;

[0089] A vacuum suction pump 3046 is used to evacuate the interior of the elastic adsorption cylinder 3043, so that a pressure difference is formed between the elastic adsorption cylinder 3043 and the outside;

[0090] And the elastic member 3045 is sleeved on the guide column 3042, and the elastic member 3045 facilitates the lower end of the elastic adsorption cylinder 3043 to elastically abut against the edge of the workpiece.

[0091] In this embodiment, preferably, the waste collection component 303 for collecting the waste after trimming includes:

[0092] A stabilizing seat 3031 is installed on the side of the stand 301, and a collecting box 3032 is arranged between two opposite stabilizing seats 3031. The collecting box 3032 is located above the conveying device 104 and does not affect the conveying of the workpiece by the conveying device 104. The conveying device 104 is a chain conveyor, which is convenient for trimming the workpiece.

[0093] A rotating material plate 3033 is rotatably mounted between the stable seats 3031 and located above the collecting box 3032. The rotating material plate 3033 is T-shaped, so that the small diameter end can be rotated and located inside the stand 301.

[0094] The rotating shaft 3034 and the vertical frame 3035 drive the rotating material plate 3033 to rotate. The vertical frame 3035 is U-shaped, and teeth are provided on the surfaces of both ends of the vertical frame 3035 along its height direction. The rotating shaft 3034 is fixed on the surface of the rotating material plate 3033 and is rotatably connected to the stable seat 3031. The outer end of the rotating shaft 3034 is sleeved with a rotating gear 3036 that meshes with the teeth. A transverse frame 3037 is provided on the inner surface of the upper end of the vertical frame 3035. The transverse frame 3037 passes through the rectangular hole 3011 opened on the surface of the vertical frame 301 and is fixed on the surface of the trimming tool holder 3022, and can be raised and lowered synchronously with the trimming tool holder 3022.

[0095] In summary, when in use, the workpiece is placed on the conveying device 104. When the workpiece is conveyed to the position of the trimming and forming structure 300, the piston rod inside the lifting cylinder 3021 extends downward, driving the trimming tool holder 3022 to move downward. The trimming tool holder 3022 simultaneously drives the horizontal frame 3037 and the vertical frame 3035 to move downward, and the rotating gear 3036 meshing with the teeth moves and rotates accordingly, driving the rotating shaft 3034 and the rotating material plate 3033 to rotate downward. The distance between the inner ends of the two rotating material plates 3033 is 40. The distance between the edge trimming tool holder 3022 and the rotating gear 3036 is gradually increased, which does not affect the downward movement of the edge trimming tool holder 3022. After the teeth are separated from the rotating gear 3036, as the edge trimming tool holder 3022 continues to move downward, the rotating material plate 3033 does not rotate, and the edge trimming tool holder 3022 moves downward to cooperate with the chain plate to trim the workpiece. The elastic adsorption cylinder 3043 is against the edge trimming surface, and the vacuum suction pump 3046 is used to form a pressure difference between the elastic adsorption cylinder 3043 and the outside world, so as to achieve the fastening and adsorption of the edge trimming waste, and the adsorption force on the edge trimming waste is greater than the edge trimming waste itself. The gravity of the piston rod in the lifting cylinder 3021 is retracted, driving the trimming tool holder 3022 to move upward, driving the vertical frame 3035 to move upward until the teeth on it mesh with the rotating gear 3036, driving the rotating shaft 3034 and the rotating material plate 3033 to move upward. At this time, the trimming tool holder 3022 is located above the rotating material plate 3033. The distribution position of the teeth and the coordination of the rotating gear 3036 will not affect the up and down movement of the trimming tool holder 3022. As the trimming tool holder 3022 continues to move upward , so that the rotating material plate 3033 is tilted to a suitable angle as a whole, the trimming tool holder 3022 stops moving, and the adsorption force on the trimming waste is removed. The trimming waste falls on the rotating material plate 3033 under the action of gravity and falls into the collection box 3032, thereby realizing the collection of waste materials. The workpiece after trimming moves with the movement of the chain plate and falls into the workpiece frame 1041 set on the left side of the conveying device 104. During the whole process, the waste edges are cut while the workpieces are collected, which reduces the trouble of subsequent separate processing and improves the efficiency of workpiece forming processing.

[0096] Embodiment 4

[0097] This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0098] The material is injected into the mixing and accelerating structure 200 through the high-pressure injection molding head 101. After sufficient mixing, pushing acceleration and heating of the material, the material enters the molding device 100 through the injection pipe 202 while maintaining a suitable flow rate and temperature. After molding by the molding device 100, the workpiece is ejected and transferred to the conveying device 104 through the unloading robot arm 103. The edge of the workpiece is trimmed and formed by the trimming molding structure 300, and the workpiece and the trimming waste are quickly separated, and then the trimmed workpiece can be collected.
