[0014] The design principle of the present invention: The bionic golden arowana needs to combine the appearance with the function of being easy to install and disassemble, so the control circuit part needs to be placed in the fish body. Considering the operability of placing the control circuit inside the fish body, the present invention provides a bionic golden arowana with a cavity in the middle of the fish body and an opening in the cavity. The cavity in the middle is used to place the drive module. By placing the core, the core can be taken out after the injection molding operation to form a cavity in the fish body. Considering the placement and fixation of the core inside the fish body, a component that can fix the core is required. Considering the beauty of the bionic golden arowana, the opening of the cavity is set at the belly of the fish body. Considering that the opening in the middle section of the fish body will affect the fragile anal fin part, it is not advisable to set the opening in the center of the cavity. Instead, the opening is offset to one side of the middle section to bypass the anal fin part, and the offset distance is half the thickness of the anal fin.

The bionic golden arowana molded by the mechanism can further simulate the appearance and can also facilitate the early manufacturing and installation as well as the later maintenance.

DETAILED DESCRIPTION

[0049] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0050] like Figure 1 、 2 , 3, 4, 5, and 6 show a mechanism for injection molding of a flexible bionic golden arowana, comprising a mold mechanism 1000, a core mechanism 2000, a fixing mechanism 3000, and a clamping mechanism 4000.

[0051] like Figure 6 、 7, 13, 14, 15, and 16, the top of the first mold 1001 and the second outer membrane tool 1002 are respectively provided with two threaded holes, the inner surfaces of the first mold 1001 and the second outer membrane tool 1002 are provided with incomplete fish body shaped grooves, and the lower part of the fish body shape of the first mold 1001 is provided with a square groove, and the depth of the square groove is two offset distances, and the square groove is used to place the first anal fin mold 1003 and the second anal fin mold 1004. The thickness of the first anal fin mold 1003 and the second anal fin mold 1004 are both an offset distance, the first anal fin mold 1003 is an anal fin shape and a partial tail fin shape, the second anal fin mold 1004 is an anal fin shape and a partial tail fin shape, the first anal fin mold 1003 and the second anal fin mold 1004 have mirror symmetry, and when the first anal fin mold 1003 is matched with the square groove When combined, the plane where the surface of the first anal fin mold 1003 lies is the mid-section of the fish body. At this time, the shape formed by the first anal fin mold 1003 and the first mold 1001 is a complete fish body shape. When the second anal fin mold 1004 is matched with the square groove, the second anal fin mold 1004 coincides with the inner surface of the first mold 1001, and the surface is an open surface. The thickness of the first mold 1001 and the second mold 1002 differ by two offset distances. A groove is provided on the inner surface of the second mold 1002. When the first mold 1001, the first anal fin mold 1003, the second anal fin mold 1004, and the second mold 1002 are matched, a fish body cavity is formed inside. Due to the existence of the groove on the inner surface of the second mold 1002, a deep hole is formed at the matching position of the first mold 1001 and the second mold 1002. The deep hole is used to place the core mechanism. The fish body-shaped periphery of the first mold 1001 and the second mold 1002 is provided with a U-shaped groove, which is used to place a sealing strip. The sealing strip 1005 is made of silicone rubber material with a certain deformation ability. The periphery of the U-shaped groove of the first mold 1003 is provided with nineteen threaded holes, and the periphery of the U-shaped groove of the second mold 1002 is provided with nineteen through holes. The first mold 1001 and the second mold 1002 are connected by a cross screw 1006. Positioning pin holes are provided on both sides of the matching point of the first mold 1001 and the second mold 1002. The pin is provided on the second mold and the hole is provided on the first mold.

[0052] like Figure 6 、 8, 9, 10, 11, 17, 18, the support mechanism 2100, the first core mechanism 2200 and the second core mechanism 2300 together form the core mechanism 2000, the first core mechanism 2200 is fixed to the support plate 2101 by a cross screw 2203, and the second core mechanism 2300 is fixed to the support plate 2101 by a cross screw 2303. The support plate 2101 is made of hard material. The upper part of the support plate 2101 is fixed with the first core mechanism 2100 and the second core mechanism 2300, and the lower part passes through the cavity and is installed in the deep hole of the mold. The support plate 2101 not only fixes the first core mechanism The structure 2100 and the second core structure 2300 also play the role of opening the cavity. Considering that the opening needs to be closed during the operation of the bionic golden arowana and opened during the early installation and later maintenance, it is necessary to have a lock 2102 that is integrated into the glue injection and can open and close the opening. A pair of locks 2102 are respectively integrated into the glue injection on both sides of the opening. A threaded through hole is provided in the middle of the lock 2102. A pair of locks 2102 are connected by a cross screw 2103. Considering that the lock 2102 will not fall off from the bionic golden arowana during multiple opening and closing processes, a shoulder is provided in the middle of the cylindrical lock 2102, and two The arc through hole makes the lock buckle 2102 more secure during the glue injection. There are three pairs of lock buckles 2102, which are respectively set at the front, middle and rear of the lower part of the fish body and connected to the support plate 2101 through cross screws 2103. Considering that the installation position of the lock buckle 2102 should be symmetrical about the middle section of the fish body, and the support plate 2101 is installed at an offset distance on one side of the middle section of the fish body, the length of the cross screw 2103 selected should be at least the sum of the length of the two lock buckles 2102 plus the two offset distances. The lock buckle 2102 at one end is installed at the nail cap of the cross screw 2103, and the lock buckle 2102 at the other end is installed at the cross screw 210 3. Considering that the mass distribution of the cross screw 2103 on the support plate 2101 after installation is asymmetrical and will cause it to tilt, the cross screw 2103 and the support plate 2101 are fixed by installing a nut 2104. After the pouring operation is completed, the cross screw 2103 is removed and the nut 2104 is taken out. The installation sequence is to first fix one end of the lock buckle on the nail cap of the cross screw 2103, then pass the cross screw 2103 through the through hole at the bottom of the support plate 2101, then install the nut 2104 to fix the cross screw 2103, and then install the other end of the lock buckle 2102 on the top of the cross screw 2103.

[0053] like Figure 6 、 8As shown in Figures 10, 19, 20, 21, 22, 23, and 24, a groove is provided on the surface of the first core 2201, and the depth of the groove is equal to the thickness of the support plate 2101. When the first core 2201 is matched with the second core 2202, a gap will be formed at the connection due to the groove of the first core 2201. Four threaded holes are provided on the surface of the groove, and four circular through holes are provided on the surface of the second core 2202. The first core 2201, the support plate 2101, and the second core 2202 are connected by cross screws 2203. Considering that the first core 2201 and the second core 2202 should be symmetrical about the middle cross section of the fish body after matching, and the support plate 2101 is installed at an offset distance on one side of the middle cross section of the fish body, the first core 2201 The width of the core 2201 is two offset distances greater than the width of the second core 2202. The first core 2201 and the second core 2202 are matched to form a cabin at the upper part. A notch is provided on one side of the cabin. The depth of the notch is greater than the width of the first elastic fiber material 2207, and the width of the notch is equal to the thickness of the first elastic fiber material 2207. Two through holes are provided at both ends of the first elastic fiber material 2207. The first steering wheel connecting block 2206 is placed in the cabin. Four threaded holes are provided on the circular surface of the first steering wheel connecting block 2206, and a boss is provided in the middle. A square through hole is provided on one side of the boss. The first elastic fiber material 2207 is clearance-matched with the slot hole of the first steering wheel connecting block 2206 through the square through hole. Two circular through holes are provided on one side, and the other side Two threaded through holes are provided, and the first elastic fiber material 2207 is connected to the first steering wheel connecting block 2206 through a cross screw 2208. The first elastic fiber material 2207 extends out from the slot. Considering that the first steering wheel connecting block 2206 is connected to the drive module, a large force will be generated at the connection between the first steering wheel connecting block 2206 and the first elastic fiber material 2207. At the same time, considering the difficulty of processing the first steering wheel connecting block 2206 set, the first steering wheel connecting block 2206 set is made of a high-strength, high-toughness, and easy-to-process material, such as PE material. At the same time, the first elastic fiber material 2207 is connected to the first steering wheel connecting block 2206 as part of the transmission mechanism, and the other part is integrated into the glue injection to drive the fish body. Taking into account the efficiency of the first elastic fiber material 2107 in transmitting force and the fact that it will fall off from the bionic golden arowana after long-term operation, a first fixing piece 2209 is installed at the other end of the first elastic fiber material 2207. Square through holes are provided on the upper and lower sides and one side of the surface of the first fixing piece 2209, two circular through holes are provided in the middle of one side, and two threaded through holes are provided in the middle of the other side. The first fixing piece 2209 is connected to the first elastic fiber material 2207 by a cross screw 2210. The first fixing piece 2209 is integrated into the injection glue and has a large contact area with the injection glue. At the same time, the upper and lower square through holes are wrapped by the injection glue, further reinforcing the position of the first fixing piece 2209 in the injection glue, thereby making the first elastic fiber material 2207 more secure.Considering that the first steering wheel connecting block 2206 needs to be connected to the first elastic fiber material 2207 fixed in the glue injection and needs to be connected to the driving module at the same time, the first steering wheel connecting block 2206 cannot be removed from the fish body after the glue injection work is completed along with the first core 2201 and the second core 2202, nor can it be wrapped by the glue injection. Therefore, a part is provided at the cabin where the first steering wheel connecting block 2206 is placed to prevent the glue injection from entering the cabin. At the same time, considering that the part can be easily taken out from the outer periphery of the first steering wheel connecting block 2206 after the glue injection work is completed, the part is divided into two parts, namely the first steering wheel cover 2204 and the second steering wheel cover 2205. The first steering wheel connecting block 2206 The first steering wheel cover 206 and the second steering wheel cover 2206 are enclosed by the first steering wheel connecting block 2206. Both the first steering wheel cover 2004 and the second steering wheel cover 2205 are equipped with bosses, which cooperate with the remaining portion of the notch to seal the cabin. Since the first steering wheel cover 2204 and the second steering wheel cover 2205 should be removed after the glue injection operation is completed, the cooperation between the first steering wheel cover 2204 and the second steering wheel cover 2205 and the cabin cannot guarantee absolute airtightness. Note that during the glue injection operation, the glue liquid level rises from the bottom to the top, and the viscosity coefficient of the glue is relatively high. Therefore, the air in the cabin cannot be completely eliminated, and a small amount of glue will enter the cabin, but this has no effect on the operation of the first steering wheel connecting block 2206.

[0054] like Figure 6 、 8, 11, 25, 26, 27, 28, 29, 30, a groove is provided on the surface of the third core 2301, and the depth of the groove is equal to the thickness of the support plate 2101. When the third core 2301 is matched with the fourth core 2302, a gap will be formed at the connection due to the groove of the third core 2301. Four threaded holes are provided on the surface of the groove, and four through holes are provided on the surface of the fourth core 2302. The third core 2301, the support plate 2101, and the fourth core 2302 are connected by cross screws 2303. Considering that the third core 2301 and the fourth core 2302 should be symmetrical about the middle cross section of the fish body after matching, and the support plate 2101 is installed at an offset distance on one side of the middle cross section of the fish body, the third core 2301 The width is two offset distances larger than the width of the fourth core 2302. Considering that the cavity formed by removing the core after the injection molding work is completed is used to place the drive module, the drive module needs to be installed and fixed on the part integrated into the injection molding during installation, that is, the second fixing piece 2310. Grooves are provided at the lower part of the third core 2201 and the fourth core 2202. A threaded hole is provided in the center of the two grooves. Two threaded holes are provided at the lower part of the second fixing piece 2310. Due to the limited size of the bottom of the second fixing piece, the specifications of the threaded holes at the lower part of the second fixing piece are smaller than the specifications of the threaded holes of the third core and the fourth core. The first connecting piece 2304 and the second connecting piece 2307 are both provided with two circular through holes, one large and one small. The width of the first connecting piece 2304 is equal to that of the third core 2301. The width of the lower part, the width of the second connecting piece 2307 is equal to the width of the lower part of the fourth core 2302, the second fixing piece 2310 is connected and fixed to the first connecting piece 2304 by a cross screw 2305, the second fixing piece 2310 is connected and fixed to the second connecting piece 2307 by a cross screw 2308, the first connecting piece 2304 is fixed to the third core 230 by a cross screw 2306, the second connecting piece 2302 is connected and fixed to the fourth core 2302 by a cross screw 2309, the second fixing piece 2310 is provided with square through holes in the horizontal and vertical directions, the purpose is to integrate the glue into the square through holes so that the second fixing piece 2310 is more secure during the glue injection, the middle part of the second fixing piece 2310 is provided with a boss, and the lower part of the boss is provided with two 2302, and the boss is fitted with the groove formed by the third core 2301 and the fourth core 2302. The length of the boss is slightly greater than the depth of the groove. There is a certain space between the second fixing piece 2310 and the third core 2301 and the fourth core 2302 for integrating the injection. After the injection is completed, only the boss part of the second fixing piece 2310 is exposed outside the injection, and the exposed part is used to connect and fix the drive module. After the third core 2301 and the fourth core 2302 are matched, a cabin is formed at the upper part. A notch is provided on one side of the cabin. The depth of the notch is greater than the width of the second elastic fiber material 2314, and the width of the notch is equal to the thickness of the second elastic fiber material 2314. Two through holes are provided at both ends of the second elastic fiber material 2314.The second steering wheel connecting block 2313 is placed in the cabin. Four threaded holes are provided on the circular surface of the second steering wheel connecting block 2313, and a boss is provided in the middle. A square through hole is provided on one side of the boss, two circular through holes are provided on one side, and two threaded holes are provided on the other side. The second elastic fiber material 2314 is connected to the second steering wheel connecting block 2313 by a cross screw 2315. The second elastic fiber material 2314 extends out from the slot. Considering that the second steering wheel connecting block 2313 is connected to the drive module, a large force will be generated at the connection between the second steering wheel connecting block 2313 and the second elastic fiber material 2314. At the same time, considering the difficulty of processing the second steering wheel connecting block 2313 set, the second steering wheel connecting block 2313 set is made of high-strength, high-toughness, and easy-to-process material. The second elastic fiber material 2314 is made of a material, such as PE material, and the second elastic fiber material 2314 is connected to the second steering plate connecting block 2313 as a part of the transmission mechanism, and the other part is integrated into the injection glue to drive the fish body. Considering that the second elastic fiber material 2314 is long and will affect the efficiency of force transmission, and the other end of the second elastic fiber material is at the fish tail with a smaller thickness, it is not advisable to set a fixing piece at the end of the first elastic fiber material to improve the force transmission efficiency on the second elastic fiber material. Therefore, two through holes are set at the other end of the second elastic fiber material 2314, and the injection glue wraps the through holes and solidifies to improve the transmission efficiency of the second elastic fiber material. Considering that the second steering plate connecting block 2313 needs to be fixed with the second elastic fiber material 2314 in the injection glue. The fourth core 2302 is connected to the fish body, and the fourth core 2302 is connected to the fish body. Therefore, the second steering wheel connecting block 2313 cannot be removed from the fish body after the glue injection work is completed along with the third core 2301 and the fourth core 2302, nor can it be wrapped by the glue injection. Therefore, a part is set at the cabin where the second steering wheel connecting block 2313 is placed to prevent the glue injection from entering the cabin. At the same time, considering that the part is convenient to be taken out from the periphery of the second steering wheel connecting block 2313 after the glue injection work is completed, the part is divided into two parts, namely the third steering wheel cover 2311 and the fourth steering wheel cover 2312. The third steering wheel cover 2311 and the fourth steering wheel cover 2312 wrap the second steering wheel connecting block 2313. The third steering wheel cover 2311 and the fourth steering wheel cover 2312 are both provided with bosses, and the two bosses cooperate with the remaining parts of the slots to make The cabin is closed. Since the third steering wheel cover 2311 and the fourth steering wheel cover 2312 should be removed after the glue injection operation is completed, the cooperation between the third steering wheel cover 2311 and the fourth steering wheel cover 2312 and the cabin cannot ensure the absolute airtightness of the cabin. It is noted that during the glue injection operation, the glue liquid level is from bottom to top. At the same time, the viscosity coefficient of the glue injection is large, and the air in the cabin cannot be completely eliminated. A small amount of glue will enter the cabin, but it will not affect the operation of the second steering wheel connecting block 2313. Considering that the streamlined shape of the fish body is wide in the middle and narrow at the back, the space where the first core mechanism 2200 is located is larger, and the space where the second core mechanism 2300 is located is smaller. At the same time, the research and analysis of the fish body shows that the middle part of the fish body has greater force than the tail, and a larger drive module is used in the middle part.The first core 2201 is larger than the third core 2301, the second core 2202 is larger than the fourth core 2302, the first steering wheel connecting block 2206 is larger than the second steering wheel connecting block 2313, the first steering wheel cover 2204 is larger than the third steering wheel cover 2311, the second steering wheel cover 2205 is larger than the fourth steering wheel cover 2312, and the length of the second elastic fiber material 2314 is longer than the length of the first elastic fiber material 2207.
