Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a high-efficiency disc vertical injection molding machine with multiple stations. Background Art

[0002] The disc vertical injection molding machine is a mechanical device, usually composed of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, a safety monitoring system, etc. After the mold is installed on the rotatable disc, the disc's rotation and lifting injection molding mechanism can realize the operation of loading and unloading on one side while the other side is injection-molded. It is often used in the processing of plastic lines;

[0003] After searching, the applicant found that a Chinese patent disclosed "a disc vertical injection molding machine with multi-station high-efficiency molding", and its publication (announcement) number is "CN217476435U". This patent mainly uses the setting of a push plate. When the mold disc rotates to switch the mold position, the injection-molded wire row is automatically lifted and unloaded along the rotation of the mold disc, thereby eliminating the step of manual demolding and unloading, which is beneficial to improving work efficiency and reducing labor consumption for users. The rotation of the mold disc is used for control, and the function is more stable. The setting of the limit column allows the push plate to push the wire row to be demolded in an inclined state, so that the wire row can be directly separated from the area above the mold disc along the push of the push plate, further improving the efficiency of unloading. However, in this comparative example, the push plate tilts to push the mold off during demolding, and the inclined demolding will cause the position of the finished mold to be unstable. For this reason, we propose a high-efficiency disc vertical injection molding machine with multiple stations. Utility Model Content

[0025] In this embodiment, the top and bottom surfaces of the four sets of mold plates 41 are respectively provided with mold grooves 411 and through holes, and the diameter of the through holes is smaller than the diameter of the mold grooves 411, and mold bottom plates 412 are movably installed in the four sets of mold grooves 411;

[0026] After the driving motor 3 is started, it will drive the turntable 4 to rotate, thereby driving the four groups of mold plates 41 on the turntable 4 to rotate synchronously, so that the mold plates 41 can be moved in sequence to the bottom of the injection assembly 10, the bottom of the die assembly 11 and the top of the lifting assembly 8. Through the setting of the mold bottom plate 412, the injection and die pressing operations can be completed in the mold groove 411.

[0027] In this embodiment, the lifting assembly 8 includes a second electric push rod 81, a support plate 82 and a push column 83. The support plate 82 is fixedly connected to the output end of the second electric push rod 81. Four groups of push columns 83 are provided, and the push columns 83 are adapted to the through holes.

[0028] After the second electric push rod 81 is started, it will drive the support plate 82 to move, thereby driving the push column 83 to move. The push column 83 can pass through the through hole to push the mold bottom plate 412 upward. After the top surface of the mold bottom plate 412 is pushed to be flush with the top surface of the mold plate 41, starting the first electric push rod 71 can drive the push plate 72 to move.

[0029] In this embodiment, a conveying assembly 9 is installed on the top surface of the base 1. The conveying assembly 9 includes a conveyor belt 91. The conveyor belt 91 is located on the right side of the turntable 4, and the top surface of the conveyor belt 91 and the top surface of the turntable 4 are at the same height;

[0030] The push plate 72 moves rightward to push the mold formed on the top surface of the mold plate 41 onto the conveyor belt 91 on the right side of the turntable 4, thereby preventing the mold from piling up on the turntable 4 and affecting work efficiency.

[0031] Specifically, by setting up the pushing component 7 and the lifting component 8, after the mold plate 41 is rotated to the top of the lifting component 8 through the turntable 4, the second electric push rod 81 will drive the pushing column 83 to push the mold bottom plate 412 upward, so that the mold in the mold groove 411 is pushed out of the mold plate 41, and then the first electric push rod 71 is used to drive the pushing plate 72 to push the mold from the top surface of the mold plate 41 to the conveyor belt 91 in parallel, so as to avoid tilting the mold and causing the position of the finished mold to be unstable.

[0032] Example 2, please refer to the attached Figure 1 -Attached Figure 6 A high-efficiency disc vertical injection molding machine with multiple stations includes a base 1, a support frame 2 is installed on the bottom surface of the base 1, a drive motor 3 is installed in the cavity of the support frame 2, and a turntable 4 is fixedly connected to the top of the roller shaft of the drive motor 3, and four groups of mold plates 41 are fixedly installed on the top surface of the turntable 4 at equal intervals, a fixed frame 5 is fixedly connected to the top surface of the base 1, a support block 6 is installed on the bottom surface of the fixed frame 5, and a pushing component 7 is installed in the cavity of the support block 6, the pushing component 7 includes a first electric push rod 71 and a push plate 72, the left side of the push plate 72 is fixedly connected to the output end of the first electric push rod 71, and a lifting component 8 is installed on the top surface of the base 1.

[0033] In this embodiment, a liquid injection assembly 10 and a die assembly 11 are installed on the top surface of the fixing frame 5.

The top surface and the bottom surface of the liquid infusion tube 102 are respectively connected to the bottom surface of the liquid storage tank 101 and the top surface of the connecting block 103. The top end of the liquid injection tube 104 is connected to the bottom surface of the connecting block 103.

[0034] The liquid injection pipe 104 injects the plastic raw liquid in the liquid storage tank 101 into the mold groove 411 of the mold plate 41 below.

[0035] In this embodiment, an electric control valve is installed on the surface of the infusion tube 102, four groups of injection tubes 104 are provided, and the horizontal height of the bottom surface of the injection tube 104 is higher than the horizontal height of the top surface of the mold plate 41;

[0036] The electric control valve can control the amount of each infusion. The horizontal height of the bottom surface of the injection tube 104 is higher than the horizontal height of the top surface of the mold plate 41 to prevent the injection tube 104 from blocking the mold plate 41 when the turntable 4 rotates.

[0039] Specifically, by setting up four groups of mold plates 41, the rotation of the turntable 4 will drive the four groups of mold plates 41 to move synchronously, so that when one group of mold plates 41 is demolding, the other three groups of mold plates 41 can perform injection molding, compression molding and static operations respectively at the same time, which has high work efficiency.

[0040] Working principle:

[0041] First, the plastic stock solution in the liquid storage tank 101 is injected into the mold groove 411 of the mold plate 41 directly below through the injection pipe 104, and then the driving motor 3 is started to drive the turntable 4 to rotate, so that the mold plate 41 injected with the stock solution moves to directly below the pressing plate 112, and then the cylinder 111 is started to drive the pressing plate 112 to move downward for pressing. After the pressing is completed, the turntable 4 is used to drive the mold plate 41 with the pressed mold to move aside and let it stand still. After standing still, it is moved to directly above the lifting component 8, and then the second electric push rod 81 is started to drive the support plate 82 to move, thereby driving the push column 83 to move. The push column 83 can pass through the through hole to push the mold bottom plate 412 upward. After pushing the top surface of the mold bottom plate 412 to be flush with the top surface of the mold plate 41, starting the first electric push rod 71 can drive the push plate 72 to move to the right to push the mold on the top surface of the mold plate 41 onto the conveyor belt 91. At this point, the entire workflow is completed.
