Description

Technical Field

[0001] The invention relates to the technical field of plastic bottle embryo production, in particular to a plastic bottle embryo injection molding device which is easy to disassemble and clean. Background Art

[0002] Plastic (PET) bottles are widely used in the packaging of products such as carbonated beverages, alcohol, juice, mineral water, edible oil, condiments, medicines, cosmetics, pesticides and detergents due to their excellent physical properties and chemical stability. When producing plastic bottles, this technology uses an injection molding machine to inject pre-dried and melted PET material into a special mold cavity under high pressure. After cooling and solidification, the plastic bottle embryo with a certain shape and size is taken out, and then the embryo is blown into a plastic bottle through subsequent blow molding.

[0003] Nowadays, when plastic bottle embryos are produced by injection molding, the hot melt of plastic needs to be injected into the corresponding injection mold to shape the embryo. When the injection molding mold is installed, the mold is often screwed and installed using the corresponding bolts. However, this installation method requires many manual operation steps for disassembly and assembly of a large number of molds, and the operator needs to screw multiple sets of bolts in sequence, which is time-consuming and labor-intensive, and affects the efficiency of subsequent cleaning of the mold. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a plastic bottle preform injection molding device which is easy to disassemble and clean, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plastic bottle preform injection molding device that is easy to disassemble and clean, comprising a processing table, the bottom four corner surfaces of the processing table are vertically fixed with support legs, the top of the processing table is detachably mounted with molds, and the number of molds is several groups, and the bottom of the processing table is vertically fixed with a hollow frame;

[0006] Each of the two ends of the outer side of the hollow frame is slidably mounted with a sliding plate, and each of the hollow frames is rotatably provided with an adjustment mechanism inside, and the adjustment mechanism and the sliding plate are transmission-connected, and a limiting mechanism is slidably mounted at the bottom of the processing table, and a pushing mechanism is provided between the limiting mechanism and the sliding plate;

[0007] An installation frame is transversely fixedly installed between the outer bottoms of the hollow frames, a synchronization mechanism is arranged inside the installation frame, and the synchronization mechanism is transmission-connected with the adjustment mechanism.

[0008] By adopting the above-mentioned technical scheme, through the synchronous driving action of the synchronization mechanism on multiple groups of adjustment mechanisms, and under the transmission conversion action of the pushing mechanism, the adjustment mechanism and the limiting mechanism, the multiple groups of limiting plugs located below the mold body can be synchronously moved horizontally in or out inside the plug-in column, and then combined with the clamping and limiting action of the limiting plugs on the plug-in column, the mold body can be quickly installed and disassembled, reducing the operating steps and labor consumption required for the operator to disassemble and assemble the mold body, thereby improving the subsequent cleaning and maintenance efficiency of the inside of the mold body.

[0010] By adopting the above technical solution, the power required for the sliding plate and the pushing rod to push the transmission plate horizontally can be provided through the rotation transmission action of the rotating screw on the lifting sleeve.

[0011] As an optional scheme of the technical scheme of the present application, the limiting mechanism includes a limiting rod and a plug-in column, each of the two sides of the bottom of the mold body is vertically fixed with a plug-in column, a plug-in groove is vertically opened inside the processing table, and the plug-in column is slidably inserted into the plug-in groove, and a limiting slot is horizontally opened inside each of the plug-in columns, a transmission plate is slidably installed at the bottom of the processing table, and the number of transmission plates is the same as the number of mold bodies, and limiting rods are fixedly installed on both sides of the top of each transmission plate, and the limiting rod and the limiting slot are in the same horizontal position.

[0012] By adopting the above technical solution, a plug-in column is arranged at the bottom of the mold body, and a limiting plug rod is horizontally arranged inside the processing table. After the limiting plug rod is pushed and inserted into the limiting slot inside the plug-in column, the plug-in column is prevented from being arbitrarily moved vertically out of the limiting plug rod, and the mold body can be clamped and fixed.

[0014] By adopting the above technical solution, through the structural action of the movable groove and the guide rod, when the transmission plate is pushed, the transmission plate and the limiting plug rod will not move laterally at will and can only move horizontally, thereby ensuring the stability of the clamping reinforcement of the mold body.

[0016] By adopting the above technical solution, the vertical moving force of the sliding plate can be converted into a horizontal driving force on the transmission plate and the limiting plug rod through the driving conversion action of the push rod.

[0017] As an optional scheme of the technical scheme of the present application, the synchronization mechanism includes a transmission sprocket and a transmission chain, a rotating rod is installed inside the installation frame for vertical rotation through a bearing, and the top of the rotating rod and the bottom of the rotating screw are fixedly connected, a servo motor is fixedly installed on the side of the bottom of the installation frame, and the top of the servo motor transmission shaft is fixedly connected to the bottom of the rotating rod through a coupling, a transmission sprocket is fixedly sleeved on the outer surface of the middle end of each rotating rod, a transmission chain ring is meshingly sleeved on the outer side of the transmission sprocket, and the transmission chain ring is rotatably installed inside the installation frame.

[0018] By adopting the above technical solution, through the meshing transmission action of the transmission chain ring and the transmission sprocket, the servo motor can drive multiple groups of rotating rods and rotating screws to rotate synchronously and in the same direction when running.

[0019] As an optional solution of the technical solution of the present application, a support frame is fixedly installed on the middle surface of the top of the processing strip, electric push rods are vertically fixedly installed on both sides of the top of the support frame, and a lifting frame is fixedly installed on the bottom of the electric push rod transmission shaft, and the lifting frame is slidably installed on the support frame, and a discharge pipe is vertically fixedly installed on the side of the lifting frame, and the number of the discharge pipes is several groups, each of the discharge pipes is fixedly connected to the top of a bellows, and each of the bellows is fixedly connected to the top of a feed pipe.

[0020] By adopting the above technical solution, the feed pipe and the discharge pipe are connected through the structural action of the electric push rod and the bellows, so the vertical position of the discharge port of the discharge pipe can be adjusted to ensure that the discharge pipe can stably and leak-free discharge the hot melt plastic into the mold for injection molding.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention vertically arranges a limit column at the bottom of the mold body, and horizontally slides a limit plug rod inside the processing table, and combines the transmission plate to drive the limit plug rods on both sides of the bottom of the same mold body. Then, a rotating screw is rotatably arranged inside the hollow frame. Combined with the rotational transmission effect of the rotating screw on the lifting sleeve, when the rotating screw rotates, it can drive the lifting sleeve sleeved on its surface to move vertically synchronously. After that, the two ends of the push rod are respectively hinged to the outer sides of the sliding plate and the transmission plate in combination with the rotating shaft, so that the push rod can lift the lifting sleeve. The vertical movement force of the sleeve is converted into the horizontal movement force of the transmission plate, so that the transmission plate can move horizontally at the bottom of the processing table while driving the limit rod to move horizontally inside the movable groove synchronously, so that the multiple sets of limit rods located below the mold body can be synchronously moved horizontally in or out of the plug-in column. Combined with the clamping and limiting effect of the limit rod on the plug-in column, the mold body can be quickly installed and disassembled, reducing the operator's required operating steps and labor consumption for disassembly and assembly of the mold body, thereby improving the subsequent cleaning and maintenance efficiency of the inside of the mold body.

[0023] 2. The present invention provides an installation frame at the bottom of the hollow frame in the same horizontal direction, and rotatably installs the rotating rod fixedly connected to the rotating screw rod inside the installation frame, so that after the servo motor at a single position is in operation, it drives the rotating rod and the transmission sprocket sleeved on its surface to rotate, and combined with the meshing transmission action of the transmission chain on the transmission sprocket, it can drive multiple groups of rotating rods and rotating screw rods to rotate synchronously and in the same direction, and then provide corresponding horizontal moving forces to multiple groups of transmission plates, so as to realize the synchronous disassembly and assembly of multiple groups of mold bodies, and further improve the efficiency of the staff in disassembly and assembly of the mold bodies and subsequent cleaning.

[0035] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), sliding plates 27 are slidably installed on the surfaces of both ends of the outer side of each hollow frame 23, an adjusting mechanism is rotatably arranged inside each hollow frame 23, and the adjusting mechanism and the sliding plate 27 are transmission-connected, the adjusting mechanism includes a rotating screw 24, a rotating screw 24 is vertically rotatably installed inside each hollow frame 23 through a bearing, a lifting sleeve 25 is movably sleeved on the outer surface of each rotating screw 24 through a threaded sleeve, a connecting block 26 is arranged on the outer side of each lifting sleeve 25, and the side edge of the connecting block 26 is fixedly connected to the outer side of the sliding plate 27, and a limiting slide groove 29 is vertically provided at both ends of the side of each hollow frame 23, and the connecting block 26 is slidably inserted into the limiting slide groove 29.

[0036] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4As shown), a limiting mechanism is slidably installed at the bottom of the processing table 1, and the limiting mechanism includes a limiting plug rod 22 and a plug-in column 2. The plug-in columns 2 are vertically fixedly installed on both sides of the bottom of each mold body 18. A plug-in groove 41 is vertically opened inside the processing table 1, and the plug-in column 2 is slidably plugged into the plug-in groove 41. A limiting slot 42 is horizontally opened inside each plug-in column 2. A transmission plate 21 is slidably installed at the bottom of the processing table 1, and the number of transmission plates 21 is the same as the number of mold bodies 18. Limiting rods 22 are fixedly installed on both sides of the top of each transmission plate 21, and the limiting rod 22 and the limiting slot 42 are in the same horizontal position.

[0037] In some technical solutions (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), a pushing mechanism is provided between the limiting mechanism and the sliding plate 27, and the pushing mechanism includes a pushing rod 28. Each side of the sliding plate 27 is hinged with a pushing rod 28 via a rotating shaft, and the side of the pushing rod 28 away from the sliding plate 27 is hinged to the bottom of the transmission plate 21 via a rotating shaft.

[0038] During operation, when the mold body 18 needs to be disassembled and the surface needs to be cleaned and maintained, the servo motor 34 is turned on through an external control switch to make it run and drive the rotating rod 31 located on the left side of the processing table 1 to rotate synchronously, thereby driving the transmission sprocket 32 ​​sleeved on its surface to rotate.

When the mold body 18 needs to be installed and used, the plug-in columns 2 at the bottom of the multiple groups of mold bodies 18 are aligned with the plug-in grooves 41 inside the processing table 1, and then the servo motor 34 is turned on by the external control switch to make it run in the reverse direction, and the above operation steps are repeated. The transmission plates 21 located on both sides of the outside of the hollow frame 23 can move horizontally in a synchronous manner toward each other, thereby driving the limit rod 22 to pass through the plug-in slot 41 inside the plug-in column 2, and stably fixing the plug-in column 2 inside the plug-in slot 41, thereby completing the rapid installation and use of multiple groups of molds 18, and then starting the electric push rod 13 to make it run and drive the lifting frame 14 to move vertically synchronously until the bottom of the discharge pipe 17 is close to the feed port aligned with the surface of the mold 18, and then the hot melt plastic for injection molding is transported to the inside of the mold 18 through the feed pipe 16 and the corrugated hose, and the plastic embryo is injection molded and finalized.
