[0002] In the mold industry, various molds and tools are used to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, the mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. In order to change the shape, thickness or complex shape of the molded object, an additional layer of middle mold (frame) is usually set between the upper and lower molds of the mold to make the molding space in the mold larger, which leads to the problem of opening the upper mold and the middle mold (frame) separately.

DETAILED DESCRIPTION

[0025] The present invention is further described below through specific implementation methods.

[0026] Reference Figures 1 to 4 An automatic frame opening device is shown, comprising a mold station frame 1, a lifting and turning mold mechanism 2, a limiting mechanism 3, a boosting component 4, and a mold 5.

[0027] The mold station frame 1 is used to place the mold 5, and the mold 5 includes a bottom mold 51, a frame 52, and a top mold 53. The frame 52 is movably arranged on the bottom mold 51, and one side of the top mold 53 is hinged to one side of the frame 52 so that the top mold 53 can be flipped on the frame 52. Both sides of the end of the top mold 53 are respectively provided with a protruding rod 531 protruding outward, and both sides of the frame 52 are provided with extension rods 521 extending outward; the lifting and flipping mold mechanism 2 is arranged on the mold station frame 1 and is used to drive the frame 52 to move up and down, and can drive the frame 52 and the top mold 53 to flip.

[0028] The limiting mechanism 3 is provided with two groups, and is arranged opposite to each other and is mounted above the mold station frame 1. The limiting mechanism 3 includes a limiting driving member 33 and a limiting card plate 34. The limiting driving member 33 is fixedly arranged and drivingly connected to the limiting card plate 34. The limiting driving member 33 is used to drive the limiting card plate 34 to be telescopically arranged. The lifting and flipping mold mechanism 2 drives the frame 52 and the top mold 53 to move upward and flip upward in the high position state to the state between the two limiting card plates 34. The two limiting driving members 33 can respectively drive the limiting card plates 34 to extend to the two protruding rods 531 for limiting connection, so that the top mold 53 is in a limited state, and the lifting and flipping mold mechanism 2 moves downward to separate the top mold 53 from the frame 52; the limiting card plate 34 moves toward one side of the protruding rod 531. A limiting groove 341 is provided on the side, and when the limiting clamping plate 34 is in a limiting connection with the protruding rod 531, the protruding rod 531 is embedded in the limiting groove 341; the state in which the limiting clamping plate 34 clamps the protruding rods 531 at both ends is not a state in which the top mold 53 is clamped and immobilized, but is only for limiting the top mold 53, so that the top mold 53 can be temporarily limited in the process of opening the frame 52, but when the protruding rod 531 is in the limiting groove 341, the top mold 53 is still in a movable state, because the top mold 53 and the frame 52 are hingedly arranged, so during the separation process of the frame 52 and the top mold 53, as the position of the frame 52 changes, the top mold 53 will also rotate around the protruding rod 531.

[0029] The limiting mechanism 3 also includes a mounting frame 31, a base 32, and a guide rod 35. The mounting frame 31 is arranged above the mold station frame 1, the base 32 is arranged on the mounting frame 31, the limiting driving member 33 is arranged on one side of the base 32 and passes through the base 32 to be connected with the limiting card plate 34, and the guide rod 35 is provided with two groups and is respectively arranged on one side of the limiting card plate 34 at intervals up and down, and the guide rod 35 passes through the base 32 and can be movably arranged along the base 32. The guide rod 35 ensures that the limiting grooves 341 on both sides can be aligned with the protruding rod 531 for telescopic arrangement.

[0030] The booster assembly 4 is provided with two groups, the booster assembly 4 includes a top plate 41 and a booster driving member 42, the top plate 41 is provided at the upper end of the limit card plate 34, the limit driving member 33 can drive the limit card plate 34 and the top plate 41 to move simultaneously, the top plate 41 includes a horizontal section 411 and an inclined section 412, the horizontal section 411 is provided at the upper end of the base 32, the inclined section 412 is provided at the end of the horizontal section 411 and is inclined downwardly toward the rear side of the mounting frame 31, the booster driving member 42 is provided on the inner side of the inclined section 412 and is turned toward the frame 52 and the top mold 53 The frame 52 is set in the direction, and the booster driving member 42 drives a push rod 43 to be telescopically set. The top mold 53 is in a limited state, and the push rod 43 is used to apply a thrust to the frame 52 and separate the frame 52 from the top mold 53; the lifting and flipping mold mechanism 2 moves downward to apply a downward pulling force to the frame 52, and the frame 52 and the top mold 53 may not be separated by the pulling force alone, so the booster driving member 42 is added to drive the push rod 43 to apply a downward flipping thrust to the frame 52, so that the frame 52 and the top mold 53 are easier to separate, thereby achieving the effect of opening the frame 52.

[0031] The lifting and demolding mechanism 2 includes a lifting mechanism 21, a clamping mechanism 23, and a demolding mechanism 22. The demolding mechanism 22 connects the clamping mechanism 23 and the lifting mechanism 21. The lifting mechanism 21 is connected to the clamping mechanism 23 and is used to drive the clamping mechanism 23 to lift the frame 52 up and down. When the clamping mechanism 23 is in a high position, it can be flipped around the demolding mechanism 22 along one side. The mold turning mechanism 22 includes a vertical limit plate 221 and a connecting plate 223. The vertical limit plate 221 is set on the mold station frame 1. The clamping mechanism 23 is movable up and down on the vertical limit plate 221 and can be turned along the upper end of the vertical limit plate 221. One end of the connecting plate 223 can be rotatably connected to the lifting frame 212, and the other end can be rotatably connected to the clamping mechanism 23; the lifting mechanism 21 can drive the frame 52 to rise to the high end of the vertical limit plate 221. When the lifting mechanism 21 continues to drive upward, the frame 52 will turn upward along the high end of the vertical limit plate 221.

[0032] The clamping mechanism 23 includes a rotating plate 231, a clamping plate 232, a clamping cylinder 233, and a limit block 234. The two sides of the frame 52 are provided with extension rods 521 extending outward. The clamping plate 232 is provided with a groove 235. The rotating plate 231 is provided with two groups and is movably provided on two vertical limit plates 221. The clamping plate 232 is provided on one side of the rotating plate 231. The clamping cylinder 233 is provided above the clamping plate 232. The limit block 234 is provided at one end of the clamping cylinder 233. The lifting frame 212 lifts the rotating plate 231 up to the groove 235. The extension rod 521 is wrapped around the extension rod 521, and the clamping cylinder 233 controls the limit block 234 to extend above the extension rod 521, so that the extension rod 521 is between the clamping plate 232 and the limit block 234; the state of the extension rod 521 between the clamping plate 232 and the limit block 234 is not a state of being clamped and unable to move, but it tightly limits the extension rod 521 to prevent the frame 52 from slipping during the upward flipping process. Therefore, during the flipping process of the frame 52, the frame 52 will adaptively move around the extension rod 521, and will not get stuck during the opening and closing process of the frame 52.

[0033] The vertical limiting plate 221 is provided with an elongated hole 222 , and the rotating plate 231 can move up and down within the elongated hole 222 and be turned over at the upper end of the elongated hole 222 .

[0034] The limit driving member 33 and the boost driving member 42 are air cylinders, and the lifting driving member 211 is an oil cylinder.

[0035] The working principle of this automatic frame opening device is as follows:

[0036] When the frame 52 is molded on the bottom mold 51 and the top mold 53 is molded on the frame 52, the lifting mechanism 21 drives the lifting frame 212 to drive the two rotating plates 231 to move upward at the same time, and the frame 52 is lifted up during the upward movement, and the extension rods 521 on both sides of the frame 52 are embedded in the grooves 235, and then the clamping cylinders 233 on both sides are extended at the same time to extend the limit blocks 234 to the top of the extension rods 521, so that the extension rods 521 are between the limit blocks 234 and the grooves 235;

[0037] The lifting mechanism 21 continues to drive upward to make the rotating plate 231 rise to the high end along the long hole 222 of the vertical limit plate 221 and then flip upward at the high end. When the protruding rods 531 on both sides of the top mold 53 are between the two limit clamping plates 34, the lifting mechanism 21 stops driving upward, and then the limit driving members 33 on both sides are started at the same time, so that the limit clamping plates 34 on both sides extend to the limit grooves 341 at the same time and are wrapped on the protruding rods 531, so that the top mold 53 is in a limited state. Since the top plate 41 is arranged at the upper end of the limit clamping plate 34, the boost driving member 42 is set in the direction of the rotating plate 231 at this time;

[0038] Then, the lifting mechanism 21 is driven to move downward, and the boost driving members 42 on both sides are started, so that the top rods 43 on both sides are simultaneously extended toward the rotating plate 231 and exert a thrust on the rotating plate 231. The lifting mechanism 21 exerts a pulling force on the frame 52 and the top rods 43 exert a thrust on the rotating plate 231, so that the frame 52 rotates downward and separates from the top mold 53, thereby realizing the automatic opening of the frame 52.

[0039] After the finished product operation on the frame 52 is completed, the booster drive 42 drives the top rod 43 to retract, drives the lifting mechanism 21 to move upward and makes the frame 52 re-closed on the top mold 53, and then makes the limit drive members 33 on both sides drive the limit clamping plate 34 to retract and move away from the protruding rod 531, and then continues to drive upward through the lifting mechanism 21 to make the frame 52 and the top mold 53 flip upward to a fully open mold state. After the operation on the bottom mold 51 is completed, drive the lifting mechanism 21 to move downward to make the frame 52 close to the bottom mold 51, thereby completing the mold closing action.

[0040] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
