Description

Technical Field

[0001] This invention relates to the field of resin craft manufacturing technology, specifically to a resin craft molding device and its molding process. Background Technology

[0002] Resin crafts are decorative items made primarily of resin, cast using molds. In mass production, resin crafts are typically cast using specialized molding equipment. Existing resin craft molding equipment, such as the one described in patent publication CN120056320A, includes a base, a mounting plate, molding molds, and a raw material tank. Rotating shafts, rotatably connected to the base, are fixedly mounted on both sides of the mounting plate. Multiple molding molds are arranged in two parallel groups, each comprising two assembled molding shells. A fixing seat for securing the molding molds is mounted on the mounting plate, rotatably connected to the mounting plate, and a gear is located at the lower end of the fixing seat. By using multiple molding molds, automatic feeding is achieved via the raw material tank and control valve. A first power component and a hydraulic transmission system drive the mounting plate and molding molds to rotate in different directions, ensuring that the resin material adheres evenly to the inner wall of the molding shells. This effectively guarantees the quality of the molded resin crafts and significantly improves production efficiency.

[0003] However, the above-mentioned equipment has internal molding molds that require frequent mold changes and are inconvenient to disassemble quickly during maintenance due to the variety of processes involved, thus reducing work efficiency. Therefore, we propose a more convenient and practical resin craft molding device and molding process to meet the usage requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a resin craft molding apparatus and molding process to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A resin craft molding apparatus includes a molding mechanism and an injection molding mechanism and a cooling mechanism mounted on the molding mechanism. The molding mechanism includes two support plates, each with a connecting block fixedly connected to both ends. The top of the connecting block has an insertion slot for inserting and connecting the injection molding mechanism. The side of the support plate has an insertion frame for inserting and connecting the cooling mechanism. A rotating shaft is rotatably connected between the two support plates. A first gear is fixedly connected to one end of the rotating shaft. A rotating frame is connected to the middle of the rotating shaft. The rotating frame is located between the two support plates. Several molding components are equidistantly arranged on the rotating frame. The molding assembly includes a rotating ring rotatably mounted on a rotating frame. Multiple fixing plates are fixedly arranged along the edge of the rotating ring. A fixing frame is fixedly connected to each fixing plate. A second gear is fixedly connected to the outer wall of the fixing frame. An insert strip is inserted into the center of the top of the fixing frame. A second pin is threaded to one side of the fixing plate and passes through the lower end of the insert strip. A molding mold is detachably connected to the upper end of the insert strip. A resin injection hole is opened on the top of the molding mold, and a sealing plunger is provided on the resin injection hole. The second gears of adjacent molding components mesh; One of the molding components has a third gear on one side of the second gear that meshes with the second gear. The third gear is rotatably mounted on a rotating frame, and a first motor that drives the third gear to rotate is also mounted on the rotating frame.

[0006] Furthermore, the injection molding mechanism includes four insertion plates, which are respectively inserted into the insertion slots of two support plates. A lead screw is rotatably connected between two of the insertion plates, and a sliding rod is connected between the other two insertion plates. The lead screw and the sliding rod are arranged in parallel. A second motor is installed on one side of one of the plug-in plates. The output end of the second motor is connected to a lead screw. A sliding block is threaded onto the lead screw, and another sliding block is slidably connected to the lead screw. A connecting plate is provided between the two sliding blocks, and a raw material barrel is provided on the connecting plate. An installation plate is fixedly connected to the top of the raw material barrel, and a telescopic cylinder is installed on the top of the installation plate. A movable plug is fixedly connected to the output end of the telescopic cylinder. A through hole is opened on the connecting plate, and a discharge pipe is fixedly connected to the through hole. The movable plug can slide in the discharge pipe. One end of the discharge pipe is connected to the raw material barrel, and a solenoid valve is installed at the other end of the discharge pipe.

[0007] Furthermore, the cooling mechanism includes a cooling box, a condenser installed on one side of the bottom of the cooling box, a conductive pipe fixedly connected to the output end of the condenser, plug-in blocks fixedly connected to both sides of the top of the cooling box, the plug-in blocks and plug-in frames being compatible with each other, a mounting bracket fixedly connected to one side of the top of the cooling box, a fourth gear rotatably connected to one side of the mounting bracket, the fourth gear meshing with the first gear, a third motor installed on one side of the mounting bracket, the output end of the third motor being connected to the fourth gear.

[0008] Furthermore, several fans are installed on one side of the cooling box.

[0009] Furthermore, a first pin for securing the cooling mechanism is threaded onto one side of the connector frame.

[0010] A resin craft molding process, using the above-mentioned resin craft molding apparatus.

[0011] Compared with the prior art, the beneficial effects of the present invention are: With the molding mechanism, injection mechanism, and cooling mechanism in place, during operation, the injection mechanism is first connected to the support plate. Then, the molding die is inserted into the fixing frame via a connector and secured with a second pin. Next, the injection mechanism injects resin into the molding die. After injection, a third motor drives a fourth gear to rotate in both directions, thereby rotating the first gear and the rotating shaft, causing the rotating frame to swing back and forth. Simultaneously, the first motor drives the third gear to rotate, which in turn rotates the second gear. This swinging of the rotating frame and rotation of the molding components effectively eliminates air bubbles generated during resin injection into the molding die.

[0012] When it is necessary to produce resin crafts of different shapes or specifications, the molding mold can be changed quickly, which improves the flexibility and efficiency of production and reduces the time and cost of mold changeover. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-4 As shown, the present invention provides a resin craft molding apparatus, including a molding mechanism 1 and an injection molding mechanism 2 and a cooling mechanism 3 installed on the molding mechanism 1.

[0020] The molding mechanism 1 includes two support plates 101. Each support plate 101 has a connecting block 102 fixedly connected to both ends. The top of the connecting block 102 is provided with a insertion groove 103 for inserting and connecting the injection molding mechanism 2. The side of the support plate 101 is provided with an insertion frame 104 for inserting and connecting the cooling mechanism 3. One side of the insertion frame 104 is threaded with a first pin 105 for fixing the cooling mechanism 3. A rotating shaft 106 is rotatably connected between the two support plates 101. One end of the rotating shaft 106 is fixedly connected with a first gear 107. A rotating frame 108 is connected to the middle of the rotating shaft 106. The rotating frame 108 is located between the two support plates 101. Several molding components are equidistantly arranged on the rotating frame 108.

[0021] like Figure 2 As shown, the molding assembly includes a rotating ring 109 rotatably mounted on a rotating frame 108. Multiple fixing plates 110 are fixedly arranged along the edge of the rotating ring 109. A fixing frame 111 is fixedly connected to each fixing plate 110, and a second gear 112 is fixedly connected to the outer wall of the fixing frame 111. An insert strip 114 is inserted into the center of the top of the fixing frame 111. A second pin 115 is threaded onto one side of the fixing plate 110, and the second pin 115 passes through the lower end of the insert strip 114. A molding mold 116 is detachably connected to the upper end of the insert strip 114. A resin injection hole (not marked in the figure) is opened at the top of the molding mold 116, and a sealing plunger 117 is provided on the resin injection hole.

[0022] The second gear 112 of the adjacent molding components meshes.

[0023] One of the molding components has a third gear 113 on one side of the second gear 112 that meshes with the second gear 112. The third gear 113 is rotatably mounted on the rotating frame 108, and the rotating frame 108 is also equipped with a first motor 120 that drives the third gear 113 to rotate.

[0024] During use, the injection molding mechanism 2 first inserts into the insertion slot 103 of the connecting block 102, thereby connecting with the support plate 101. Next, the molding die 116 is inserted into the fixing frame 111 via the insertion strip 114 and fixed by the second pin 115. The sealing plunger 117 is then opened, and the injection molding mechanism 2 sequentially injects the hot-melt resin material into each molding die 116. After the resin material is injected, the third motor 307 drives the fourth gear 306 to rotate forward and backward, thereby driving the first gear 107 and the rotating shaft 106 to rotate, which in turn causes the rotating frame 108 to swing back and forth. Simultaneously, the first motor 120 drives the third gear 113 to rotate, which in turn drives the second gear 112 to rotate. The swinging of the rotating frame 108 and the rotation of the molding components help to eliminate air bubbles generated during the injection of resin material into the molding die 116. Finally, the sealing plunger 117 is inserted into the resin injection hole, and the resin material inside the molding die 116 cools and solidifies.

[0025] When it is necessary to produce resin crafts of different shapes or specifications, the molding mold 116 can be quickly changed, which improves the flexibility and efficiency of production and reduces mold change time and cost.

[0026] like Figure 3 As shown, the injection molding mechanism 2 includes four plug-in plates 201, which are respectively inserted into the plug-in slots 103 of the two support plates 101. A lead screw 202 is rotatably connected between two plug-in plates 201, and a slide rod (not marked in the figure) is connected between the other two plug-in plates 201. The lead screw 202 and the slide rod are arranged in parallel. A second motor 203 is mounted on one side of one of the plug-in plates 201. The output end of the second motor 203 is connected to a lead screw 202. A sliding block 204 is threaded onto the lead screw 202, and another sliding block 204 is slidably connected to the lead screw. A connecting plate 206 is provided between the two sliding blocks 204. A raw material barrel 207 is mounted on the connecting plate 206. An mounting plate 208 is fixedly connected to the top of the raw material barrel 207. A telescopic cylinder 209 is mounted on the top of the mounting plate 208. A movable plug 210 is fixedly connected to the output end of the telescopic cylinder 209. A through hole (not marked in the figure) is opened on the connecting plate 206, and a discharge pipe 211 is fixedly connected to the through hole. The movable plug 210 can slide within the discharge pipe 211. One end of the discharge pipe 211 is connected to the raw material barrel 207, and a solenoid valve 212 is installed at the other end of the discharge pipe 211. The second motor 203 drives the lead screw 202 to rotate, thereby moving the connecting plate 206.

[0027] During use, the plug plate 201 is first inserted into the plug slot 103, and then the resin material is added into the material tank 207. Then, the second motor 203 drives the lead screw 202 to rotate, causing the sliding block 204 to move and align the discharge pipe 211 with the resin material injection hole of the molding mold 116. At the same time, the solenoid valve 212 is opened, and the telescopic cylinder 209 on the mounting plate 208 is activated, driving the movable plug 210 to squeeze the resin material in the discharge pipe 211, so that the resin material is injected into the molding mold 116. By precisely controlling the telescopic cylinder 209 to drive the movable plug 210 to move, the amount of resin material injected can be precisely controlled, reducing the influence of human factors.

[0028] like Figure 4 As shown, the cooling mechanism 3 includes a cooling box 301. A condenser 302 is installed on one side of the bottom of the cooling box 301. A conduction pipe 303 is fixedly connected to the output end of the condenser 302. Insertion blocks 304 are fixedly connected to both sides of the top of the cooling box 301. The insertion blocks 304 and the insertion frame 104 are compatible with each other. A mounting bracket 305 is fixedly connected to one side of the top of the cooling box 301. A fourth gear 306 is rotatably connected to one side of the mounting bracket 305. The fourth gear 306 meshes with the first gear 107. A third motor 307 is installed on one side of the mounting bracket 305. The output end of the third motor 307 is connected to the fourth gear 306. Several fans 308 are installed on one side of the cooling box 301.

[0029] During use, the plug block 304 is first inserted into the plug frame 104, and the cooling box 301 and the support plate 101 are fixed by the first pin 105. After the resin material is injected into the molding mold 116, the condenser 302 is started and the temperature in the cooling box 301 is reduced under the action of the conduction pipe 303. At the same time, the fan 308 accelerates the air flow, thereby reducing the temperature of the resin material in the molding mold 116, accelerating the rapid cooling and shaping of the resin material, shortening the production cycle, and improving production efficiency.

[0030] Based on the same inventive concept, a resin craft molding process is also proposed, which uses the above-mentioned resin craft molding device.

[0031] Although embodiments of the invention have been shown and described, 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 invention, the scope of which is defined by the appended embodiments and their equivalents.
