Description

Technical Field

[0001] The utility model relates to the technical field of mold locking equipment, in particular to a synchronous mold locking device for a brake mechanism. Background Art

[0002] The clamping device of the traditional injection molding machine is a three-platen type, consisting of a head plate, a second plate and a tail plate. Generally, the head plate is a fixed plate, and the second plate is connected to the tail plate through a tie rod. The clamping oil rainbow installed on the tail plate drives the second plate to open and close the mold. Compared with the traditional three-platen machine, the two-platen injection molding machine omits the tail plate in the clamping device and directly applies the clamping force to the two templates of the fixed mold. Therefore, this equipment can save a lot of materials and floor space, and its cost is low and the equipment molding precision is high;

[0003] Most of the existing two-platen injection molding machine clamping devices use a secondary fine-tuning method to ensure that the locking nut and the tie rod are precisely engaged, requiring the four tie rods to be connected to the template in a floating manner, that is, when the tie rods and the template are engaged, the positions of the four tie rods and the template engagement brake must be on the same plane to ensure that the parallelism between the moving template and the fixed template meets the requirements. Each tie rod may shift before each engagement, so it is necessary to first make a fine-tuning action on each tie rod to ensure reset and then confirm the engagement position;

[0004] The shortcomings of the above-mentioned existing technical solutions are: the brake in the two-plate injection molding machine is responsible for tightening the nuts of the pull rod and the movable platen or the fixed platen. Since the mold needs to be opened and moved, the brake needs to be closed and opened to separate the pull rod from the movable platen or the fixed platen. Since the brake device is installed on the piston of the clamping cylinder, it is difficult to ensure that the brake is completed synchronously, and the cost of the clamping mechanism is high. Utility Model Content

[0007] A synchronous mold locking device for a brake mechanism comprises a movable mold plate, the movable mold plate is fixedly connected with a mold locking high-pressure oil cylinder assembly on all four sides, the mold locking high-pressure oil cylinder assembly is provided with a brake, a single synchronous brake assembly is provided above the brake, the upper and lower middle positions of the movable mold plate are fixedly connected with a linkage swivel pin shaft, the linkage swivel pin shaft is rotatably connected with a brake linkage swivel, brake linkage rods are provided on both sides of the brake linkage swivel, the brake linkage swivel is respectively connected to the brakes on both sides through two groups of brake linkage rods, the two ends of the brake linkage rod are respectively connected to the brake linkage swivel and the brake rotation, and a brake cylinder is connected between the brakes on the left and right sides.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 2 As shown, a synchronous clamping device for a brake mechanism comprises a movable platen 14, the movable platen 14 is fixedly connected with a clamping high-pressure oil cylinder assembly 12 on all four sides, a brake 6 is arranged on the clamping high-pressure oil cylinder assembly 12, a single synchronous brake assembly 13 is arranged above the brake 6, each of the brakes 6 is provided with two brake connecting blocks 4, the two brake connecting blocks 4 are relatively parallel and provided with holes, a brake connecting shaft 5 is provided between the two brake connecting blocks 4, the upper and lower middle positions of the movable platen 14 are fixedly connected with a linkage swivel pin shaft 1, the outer periphery of the linkage swivel pin shaft 1 is fixedly connected with a linkage rotating copper sleeve 9, the outer periphery of the linkage rotating copper sleeve 9 is rotatably connected with a brake linkage swivel seat 2, both ends of the brake linkage swivel seat 2 are provided with holes, and brake connecting shafts are provided in the holes. Connecting pin shaft 8, brake linkage rods 3 are provided on both sides of the brake linkage swivel seat 2, and holes are opened at both ends of the brake linkage rod 3, wherein the hole of the brake linkage rod 3 at one end corresponds to the hole of the brake linkage swivel seat 2, and is rotatably connected through the brake connecting pin shaft 8, wherein the hole of the brake linkage rod 3 at the other end corresponds to the hole on the two brake connecting blocks 4, and is rotatably connected through the brake connecting shaft 5, and brake cylinders 7 are provided on the outer sides of the two brake linkage swivel seats 2, and the brake cylinders 7 are fixedly connected to the brake 6 at one end of the brake linkage swivel seat 2, and the output end of the brake cylinder 7 is connected to the brake cylinder connecting rod 10, and the brake cylinder connecting rod 10 is connected to the rod end joint bearing 11, and the rod end joint bearing 11 is rotatably connected to the brake 6 at the other end of the brake linkage swivel seat 2.

[0022] The working principle of the utility model: when the machine needs to close the mold, first the mold locking high-pressure cylinder assembly 12 drives the moving mold plate 14 to move toward the fixed mold plate. When the mold locking high-pressure cylinder assembly 12 stops moving, the brake cylinder 7 starts, driving the brake cylinder connecting rod 10 to extend, and the brakes 6 on the left and right sides are both subjected to a certain thrust to move outward, but the thrust size is not necessarily the same. At this time, the brake connecting blocks 4 on the left and right sides are subjected to an outward pulling force, thereby driving the brake linkage rods 3 on the left and right sides of the brake linkage swivel 2 to move outward. Since the brake linkage rods 3 on the left and right sides are rotatably connected to the brake linkage swivel 2, and the brake linkage swivel 2 is connected to the linkage swivel pin. 1 is rotatably connected, thus driving the brake linkage rotating seat 2 to gradually rotate until it is in a horizontal position. Since the brake linkage rotating seat 2 needs to rotate, a thrust force is generated to react on the brake linkage rods 3 on both sides, so that the moving distances between the brake linkage rods 3 on both sides and the brake linkage rotating seat 2 are equal, and the distances between the brake connecting blocks 4 on both sides and the brake linkage rotating seat 2 are also equal. Finally, when the brake linkage rotating seat 2 is completely horizontal, the distances between the brake linkage rods 3 and the brake connecting blocks 4 on both sides and the brake linkage rotating seat 2 are equal. At the same time, under the action of the single synchronous brake assembly 13, the brake 6 realizes complete braking. Since the brake device is installed on the locking high-pressure cylinder assembly 12, when the four locking high-pressure cylinder assemblies 12 on the movable mold plate 14 move, it cannot be guaranteed that the positions of the four brakes 6 correspond to each other. The design purpose of the brake linkage swivel seat 2, the linkage swivel seat pin shaft 1, the brake linkage rod 3, the brake connecting block 4 and the two brake cylinders 7 is to achieve that when the positions of the brakes 6 on the left and right sides are inconsistent, the brakes 6 on the left and right sides can achieve synchronous braking success. Compared with the four brake cylinders in the previous design, it not only saves the locking cost, but also enables the brake mechanisms on the left and right sides to brake synchronously.

[0023] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
