[0042] In the prior art, the injection molding machine is usually provided with four guide columns, and the holding brake device cannot ensure that the multiple guide columns are simultaneously and synchronously locked by the holding brake, thereby causing the holding brake to be out of synchronization and affecting the limiting and fixing effect of the movable mold plate.
[0043] To solve the above technical problems, the utility model provides a synchronous holding brake device and injection molding machine.
[0044] Please refer to Figure 1 In an embodiment of the utility model, the synchronous holding brake device is applied to the injection molding machine, wherein the injection molding machine comprises four guide columns 100, and the four guide columns 100 are respectively located at four corner positions of a square structure.
[0045] Specifically, the synchronous holding brake device comprises a holding brake template 200, a plurality of holding brake mechanisms 300 and a synchronous mechanism 400; the holding brake template 200 is provided with a guide column hole 210 for the guide column 100 to pass through; each holding brake mechanism 300 corresponds to each guide column 100, and the holding brake mechanism 300 is used for locking the guide column 100 by the holding brake; and the synchronous mechanism 400 is used for driving at least two holding brake mechanisms 300 to synchronously hold the brake.
[0046] The technical scheme of the utility model connects at least two holding brake mechanisms 300 by the synchronous mechanism 400, so that the synchronous holding brake operation is realized; and the multiple guide columns 100 can be simultaneously and synchronously locked by the holding brake, so that the limiting and fixing effect of the movable mold plate is ensured.
[0047] As a preferred scheme of the above embodiment, reference is made to the accompanying drawings Figures 2-3 The holding brake mechanism 300 comprises a first half brake block 310 and a second half brake block 320, and the first half brake block 310 and the second half brake block 320 are respectively arranged on opposite sides of the guide column 100, wherein the first half brake block 310 is located on one side close to the edge of the holding brake template 200; and the opposite side of the first half brake block 310 and the second half brake block 320 is provided with a concave groove 330, and when the first half brake block 310 and the second half brake block 320 are combined, the two concave grooves 330 form a groove hole corresponding to the shape of the guide column 100. In this way, in the initial state, the first half brake block 310 and the second half brake block 320 are arranged at a position where the concave grooves 330 surround the guide column 100 but do not contact the guide column 100; and when the holding brake operation is performed, the first half brake block 310 and the second half brake block 320 are combined, the concave grooves 330 of the two are combined and contact the guide column 100, so as to tightly hold the guide column 100 in the groove hole formed by the two concave grooves 330.
[0048] Further, reference is made to the accompanying drawings Figure 3The inner part of the first half gate block 310 and the second half gate block 320 is provided with an adsorption device 340, which is used to adsorb the first half gate block 310 and the second half gate block 320 to each other to lock the guide column 100. In the embodiment, the adsorption device 340 is an electromagnetic coil. When the electromagnetic coil is electrified, it generates electromagnetic induction and electromagnetic force, so that the first half gate block 310 and the second half gate block 320 generate locking force to lock the guide column 100. When the locking is finished, the electromagnetic coil is de-energized, and the electromagnetic force between the first half gate block 310 and the second half gate block 320 disappears, so that the locking of the guide column 100 is released.
[0049] Further, with reference to the accompanying drawings Figure 3 The locking mechanism 300 further comprises a reset device 350, which comprises a reset rod 351 and a reset spring 352 sleeved on the reset rod 351. The two ends of the reset rod 351 are respectively connected with the first half gate block 310 and the second half gate block 320 in a sliding manner, and the two ends of the reset spring 352 are respectively abutted with the first half gate block 310 and the second half gate block 320. The reset spring 352 is used to reset the first half gate block 310 and the second half gate block 320 to the initial state by the elastic force. In this way, when the first half gate block 310 and the second half gate block 320 are combined with each other, the reset spring 352 is compressed due to the reduced distance between the first half gate block 310 and the second half gate block 320. When the locking is finished, the elastic force of the reset spring 352 acts on the first half gate block 310 and the second half gate block 320, so that the first half gate block 310 and the second half gate block 320 are reset to the initial state.
[0050] As a preferred scheme of the above embodiment, any two adjacent groups of the locking mechanism 300 are defined as a first locking assembly. Specifically, two groups of the locking mechanism 300 in the same column of the square structure are respectively defined as the first locking assembly. It can be understood that, since the injection molding machine in the application comprises four guide columns 100, the injection molding machine comprises two groups of the first locking assembly.
[0051] With reference to the accompanying drawings Figure 4, the synchronous mechanism 400 comprises two groups of pull rod assemblies 410, each group of pull rod assemblies 410 is applied to a group of first brake band assemblies; the pull rod assembly 410 comprises a first pull rod 411 and a second pull rod 412; the first end of the first pull rod 411 is fixedly connected with the first half brake block 310 of the first brake band mechanism 300, and the second end of the first pull rod 411 is fixedly connected with the second half brake block 320 of the second brake band mechanism 300; the first end of the second pull rod 412 is fixedly connected with the second half brake block 320 of the first brake band mechanism 300, and the second end of the second pull rod 412 is fixedly connected with the first half brake block 310 of the second brake band mechanism 300; so that the first half brake block 310 and the second half brake block 320 of the two brake band mechanisms 300 are linked. By the arrangement of the pull rod assembly 410, any two adjacent groups of brake band mechanisms 300 are combined to form a whole that cooperates with each other, that is, a first brake band assembly. The pull rod assembly 410 comprises a first pull rod 411 and a second pull rod 412, the first half brake block 310 of the first brake band mechanism 300 and the second half brake block 320 of the second brake band mechanism 300 are linked by the first pull rod 411, and the second half brake block 320 of the first brake band mechanism 300 and the first half brake block 310 of the second brake band mechanism 300 are linked by the second pull rod 412. That is, when the first brake band mechanism 300 performs brake band locking operation, the second brake band mechanism 300 will be inevitably driven to perform brake band locking, thereby achieving the purpose of synchronous brake band.
[0052] Further, with reference to the accompanying drawings Figure 5 The synchronous mechanism 400 further comprises two groups of connecting rod assemblies 420, each group of connecting rod assemblies 420 is applied to a group of first brake band assemblies; the connecting rod assembly 420 comprises a rotating part 423, a first connecting rod 421 and a second connecting rod 422, the rotating part 423 is arranged between the two brake band mechanisms 300, and the rotating part 423 is rotationally connected with the brake band template 200; the first end of the first connecting rod 421 is connected with the second half brake block 320 of the first brake band mechanism 300, and the second end of the first connecting rod 421 is connected with the rotating part 423; the first end of the second connecting rod 422 is connected with the second half brake block 320 of the second brake band mechanism 300, and the second end of the second connecting rod 422 is connected with the rotating part 423; in this way, under the driving action of the rotating part 423, the second half brake block 320 of the first brake band mechanism 300 and the second half brake block 320 of the second brake band mechanism 300 are driven to move synchronously close to or away from each other by the first connecting rod 421 and the second connecting rod 422, so as to serve as the initial force for brake band locking of the brake band mechanism 300. As mentioned above, the first brake band mechanism 300 and the second brake band mechanism 300 are linked by the pull rod assembly 410, and on this basis, the first brake band mechanism 300 and the second brake band mechanism 300 can synchronously lock the guide column 100, thereby ensuring the smooth implementation of the technical scheme of the application.
[0053] As an improvement of the above-mentioned connecting rod assembly 420, since the above-mentioned connecting rod assembly 420 is to divide the four guide columns 100 into two groups of first brake clamp assemblies for linkage driving, however, there is no linkage way between the two groups of first brake clamp assemblies, so it cannot guarantee that the brake clamp mechanisms 300 between the two groups of first brake clamp assemblies can be synchronized. Based on the above consideration, the two groups of brake clamp mechanisms 300 located at the two ends of the diagonal line of the square structure are defined as the second brake clamp assemblies, and it can be understood that since the injection molding machine in the present application includes four guide columns 100, the injection molding machine includes two groups of second brake clamp assemblies.
[0054] And, referring to the accompanying drawings Figures 6-7 The above-mentioned connecting rod assembly 420 is replaced by a circular ring assembly 430, which includes a driving part 431 and coaxially arranged outer and inner circular rings 432 and 433, the centers of the outer and inner circular rings 432 and 433 are located at the center of the brake clamp template 200; the driving part 431 is used to drive the outer and inner circular rings 432 and 433 to synchronously and oppositely rotate; that is, when the outer circular ring 432 rotates clockwise, the inner circular ring 433 rotates counterclockwise.
[0055] The annular outer side of the outer circular ring 432 is connected with a third connecting rod 434 and a fourth connecting rod 435, the free ends of the third and fourth connecting rods 434 and 435 are connected with the second half brake blocks 320 of the two brake clamp mechanisms 300 of one second brake clamp assembly; so that when the outer circular ring 432 rotates clockwise, the second half brake blocks 320 of the two brake clamp mechanisms 300 of one second brake clamp assembly are driven by the third and fourth connecting rods 434 and 435 to move synchronously; that is, the second half brake block 320 located at the upper left corner moves upward, and the second half brake block 320 located at the lower right corner moves downward; that is, the brake clamp mechanisms 300 located at the upper left corner and the lower right corner are synchronously braked.
[0056] The annular outer side of the inner circular ring 433 is connected with a fifth connecting rod 436 and a sixth connecting rod 437, the free ends of the fifth and sixth connecting rods 436 and 437 are connected with the second half brake blocks 320 of the two brake clamp mechanisms 300 of the other second brake clamp assembly. So that when the inner circular ring 433 rotates counterclockwise, the second half brake blocks 320 of the two brake clamp mechanisms 300 of the other second brake clamp assembly are driven by the fifth and sixth connecting rods 436 and 437 to move synchronously; that is, the second half brake block 320 located at the lower left corner moves downward, and the second half brake block 320 located at the upper right corner moves upward; that is, the brake clamp mechanisms 300 located at the lower left corner and the upper right corner are synchronously braked.
[0057] From the above, the embodiment replaces the connecting rod assembly 420 with the ring assembly 430, so that the brake mechanisms 300 located at the four corners of the square structure are interconnected to realize synchronous brake operation on the guide column 100, thereby ensuring effective implementation of the synchronous brake scheme.
[0058] Further, with reference to the accompanying drawings Figure 7 Further, the outer ring 432 and the inner ring 433 are arranged staggeredly, so that the outer ring 432 and the inner ring 433 are located on different horizontal planes. In this way, since the outer side of the outer ring 432 and the inner ring 433 needs to be provided with connecting rods to connect the brake mechanisms 300, the outer ring 432 and the inner ring 433 are arranged staggeredly on different horizontal planes to avoid interference between the third connecting rod 434 and the fourth connecting rod 435 of the outer ring 432 and the fifth connecting rod 436 and the sixth connecting rod 437 of the inner ring 433.
[0059] Further, the driving part 431 comprises a rotary motor 4311, the driving end of the rotary motor 4311 is provided with a gear rod 4312, and the gear rod 4312 is arranged between the outer ring 432 and the inner ring 433. The inner side of the outer ring 432 is provided with a first toothed structure 4321, and the outer ring 432 is connected with the gear rod 4312 through the first toothed structure 4321. The outer side of the inner ring 433 is provided with a second toothed structure 4331, and the inner ring 433 is connected with the gear rod 4312 through the second toothed structure 4331. In this way, since the gear rod 4312 is arranged between the outer ring 432 and the inner ring 433, when the gear rod 4312 rotates, the outer ring 432 and the inner ring 433 are caused to move in opposite directions through meshing, thereby ensuring smooth implementation of the technical scheme.
