Description

Technical Field

[0001] The invention relates to the technical field of injection molding devices, and in particular to a batch injection molding device for automobile parts. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Currently, existing injection molding machines are bound to malfunction during use, and the feed hopper must be disassembled to repair the injection molding machine. Before disassembling the feed hopper, the plastic rice inside must be extracted first, and then the hopper must be lifted. It is a long process to extract the plastic rice with a vacuum pump, which affects the subsequent work efficiency.

[0003] To solve this problem, a patent application document with publication number CN118305961A discloses an injection molding machine that is easy to maintain. The device is provided with a feed switching system. The feed cut-off system includes a feed hopper, an air pumping device, an air pumping sealing device and a flap sealing device. When the air pumping device is inflated, the air pumping sealing device pushes the flap sealing device to rotate and then seals the lower end opening of the bottom of the feed hopper. The maintenance is convenient and efficient. However, in actual use, the lack of a one-way valve design becomes a potential problem point. Specifically, when the feed hopper is placed on the ground for maintenance, due to the lack of an effective locking mechanism or a one-way valve, the air pumping device (especially the air pumping plate) is prone to position displacement after losing external support (such as a crane hook), thereby weakening the pressure maintenance of the air pumping airbag, resulting in unstable air pressure in the bellows. This air pressure fluctuation directly affects the effective sealing of the flap sealing device, so that the lower end opening of the bottom of the feed hopper may not be completely closed, and ultimately causes the material to accidentally leak to the ground.

[0004] This problem not only increases the burden of subsequent cleaning work, but also significantly reduces the overall efficiency of maintenance operations. Continuously relying on a crane to keep the pump in place is not only unrealistic, but also greatly limits the flexible use of other equipment on the production site. Summary of the invention

[0059] It should be noted that a rectangular groove (not shown in the figure) is provided on the translation material holder 526 described in this embodiment. The rectangular groove is designed so that when the translation material holder 526 moves, the driving gear holder 525 can move out of the translation material holder 526 through the rectangular groove.

[0060] It should also be noted that the first reciprocating screw rod 521 and the first guide rod 522 are always out of contact with the translation material holder 526 .

[0061] It is understandable that a slide groove is provided on the base 51 to facilitate the sliding of the translation material holder 526 .

[0062] Specifically, the structure and connection relationship of the hopper translation assembly 52 are further explained. When in use, the dual transmission mechanism 527 operates according to the instructions, first driving the first reciprocating screw 521 to rotate, and the rotation of the first reciprocating screw 521 synchronously drives the driving gear seat 525 to move, and the movement of the driving gear seat 525 triggers the operation of the hopper cutting assembly 53. The operation of the hopper cutting assembly 53 blocks the material discharge channel, and then the dual transmission mechanism 527 operates according to the instructions, and then drives the second reciprocating screw 523 to rotate. The rotation of the second reciprocating screw 523 synchronously drives the translation material seat 526 to move to the side away from the feed port 421, and the use effect is good.

[0063] In one embodiment of the present invention, Figure 6-Figure 7 As shown, the dual transmission mechanism 527 includes a first one-way transmission 5271, a second one-way transmission 5272, a first side gear 5273, a middle gear 5274, a second side gear 5275 and a third driving motor 5276, wherein the first one-way transmission 5271 and the second one-way transmission 5272 are respectively rotatably connected to the inner wall of the base 51 and are arranged in sequence along the Y-axis direction, the first side gear 5273, the middle gear 5274 and the second side gear 5275 are respectively rotatably connected to the surface of the base 51 and are arranged in sequence along the Y-axis direction, the first side gear 5273 and the second side gear 5275 are respectively meshed with the middle gear 5274, one end of the first one-way transmission 5271 is fixedly connected to one end of the first reciprocating screw rod 521, and the other end of the first one-way transmission 5271 is fixedly connected to the first reciprocating screw rod 521. One end is fixedly connected to one end of the central axis of the first side gear 5273, one end of the second one-way transmission 5272 is connected to one end of the second reciprocating screw 523, the other end of the second one-way transmission 5272 is fixedly connected to one end of the central axis of the second side gear 5275, the third drive motor 5276 is fixedly connected to the surface of the base 51, and is fixedly connected to one end of the central axis of the middle gear 5274; the transmission directions of the first one-way transmission 5271 and the second one-way transmission 5272 are opposite; encoders 100 are respectively arranged on the surfaces of the first drive motor 454, the second drive motor 455 and the third drive motor 5276, and the controller 2 is respectively connected to the third drive motor 5276 and the encoder 100 through the control bus to realize precise command transmission and comprehensive monitoring of the equipment operation status.

[0064] It should be noted that the first one-way transmission 5271 and the second one-way transmission 5272 described in this embodiment are both ratchet one-way transmissions.

[0065] Specifically, the structure and connection relationship of the dual transmission mechanism 527 are further explained. The dual transmission mechanism 527 can not only drive the feeding hopper 6 to move horizontally, but also drive the hopper cutting component 53 to operate before the feeding hopper 6 moves, thereby blocking the feeding channel. The use effect is good. When in use, the third drive motor 5276 operates according to the instruction, and the operation of the third drive motor 5276 synchronously drives the middle gear 5274 to rotate. The rotation of the middle gear 5274 synchronously drives the first side gear 5273 and the second side gear 5275 to rotate. Since the first one-way transmission 5271 is connected to the first one-way transmission 5271, the second one-way transmission 5271 is connected to the first one-way transmission 5271. The transmission directions of the two one-way transmission devices 5272 are opposite; therefore, when the third drive motor 5276 rotates, only one set of reciprocating screws can be driven to rotate through the one-way transmission device. For example, when the third drive motor 5276 rotates forward, it can only drive the first reciprocating screw 521 to rotate through the first one-way transmission device 5271; when the third drive motor 5276 rotates reversely, it can only drive the second reciprocating screw 523 to rotate through the second one-way transmission device 5272. Before moving the feeding hopper 6, it is necessary to block the unloading channel first. Therefore, it is necessary to control the third drive motor 5276 to rotate forward first, and the third drive motor 5 276 positive rotation drives the first reciprocating screw rod 521 to rotate through the first one-way transmission device 5271, and the rotation of the first reciprocating screw rod 521 synchronously drives the driving tooth seat 525 on the right side of the adjusting gear 534 in the hopper cutting assembly 53 to move to the left side. During the movement to the left side, the driving tooth seat 525 contacts and meshes with the adjusting gear 534, and synchronously drives the adjusting gear 534 to rotate. The adjusting gear 534 rotates and links the translation cylinder 531 to block the unloading channel. The encoder 100 detects the number of rotations of the third drive motor 5276 in real time, and sends the number of rotations data to the Controller 2, controller 2 determines the displacement data of the translation cylinder 531 according to the number of circles data, and the use effect is good. Then the third drive motor 5276 runs according to the instruction. The third drive motor 5276 reverses and can only drive the second reciprocating screw 523 to rotate through the second one-way transmission 5272. The rotation of the second reciprocating screw 523 drives the translation material seat 526 and the feeding hopper 6 to move to the side away from the feed port 421. The use effect is good. When the translation material seat 526 and the feeding hopper 6 move to the top of the drive box 451, the third drive motor 5276 stops running according to the instruction.

[0066] In one embodiment of the present invention, Fig. 9As shown, the hopper cutting assembly 53 includes a translation cylinder 531, a material hole 532, a third threaded screw 533 and an adjusting gear 534, wherein a column groove 61 is horizontally opened on the surface of the feed hopper 6, a U-shaped frame 62 is welded and fixed on the surface of the feed hopper 6 and is located outside the column groove 61, and a second heating assembly 63 is built into the feed hopper 6; the controller 2 is connected to the second heating assembly 63 through a control bus to achieve accurate command transmission and comprehensive monitoring of the equipment operation status; the translation cylinder 531 is horizontally slidably connected to the inner wall of the column groove 61 and the U-shaped frame 6 2 inner wall, the material hole 532 is opened at the center of the surface of the translation cylinder 531, and is connected with the inside of the feeding hopper 6; the third threaded screw 533 is rotatably connected to the inner wall of the U-shaped frame 62, one end of the third threaded screw 533 passes through the outside of the U-shaped frame 62, and is threadedly connected to the inner wall of one end of the translation cylinder 531, and the other end of the third threaded screw 533 passes through the outside of the U-shaped frame 62 and is fixedly connected with an adjusting gear 534, which is located on one side of the top of the driving gear seat 525 and meshes with the teeth on the top of the driving gear seat 525.

[0067] It should be noted that the driving gear seat 525 described in this embodiment is located on the right side of the adjusting gear 534 in the initial state.

[0068] It should also be noted that the interior of the column slot 61 is compatible with the outer dimensions of the translation column 531 .

[0069] Specifically, the structure and connection relationship of the hopper cutting assembly 53 are further explained. During the process of the driving tooth seat 525 moving to the left, it meshes with the adjusting gear 534 and synchronously drives the adjusting gear 534 to rotate. The rotation of the adjusting gear 534 synchronously drives the third threaded screw 533 to rotate. The rotation of the third threaded screw 533 synchronously drives the translation cylinder 531 to move horizontally toward one side of the third threaded screw 533. The movement of the translation cylinder 531 synchronously drives the material hole 532 to move. When the material hole 532 is not connected to the inside of the discharge port at the bottom of the feeding hopper 6, sealing can be achieved. During the process of the driving tooth seat 525 moving to the right, it meshes with the adjusting gear 534, and the linkage material hole 532 is re-connected with the inside of the discharge port at the bottom of the feeding hopper 6, so that the material falls into the material pipe 42 conveniently. By changing the contact length between the driving tooth seat 525 and the adjusting gear 534, the moving distance of the translation cylinder 531 can be changed accordingly, and the use effect is good.

[0070] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a collection opening 7 is respectively provided on the surface of the first mounting frame 31 and the top of the frame 1, and the positions are corresponding. A collection frame 8 is slidably connected to the surface of the frame 1, and the collection frame 8 is used to collect the injection molded parts that fall from the collection opening 7 to the inside of the frame 1.

[0071] Specifically, the material collection port 7 and the material collection frame 8 are provided to facilitate the collection of the injection molded parts, and the use effect is good.

[0072] In summary, an automobile parts batch injection molding device according to an embodiment of the present invention is provided with a sliding material cutting device 5. Compared with the existing flap sealing device, the sliding material cutting device 5 can firmly seal the material discharge channel and drive the feed hopper 6 to move to one side after the sealing is completed, which is convenient for subsequent maintenance.
