Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machines and relates to an injection molding device, in particular to an anti-drip injection molding device. Background Art

[0002] An injection molding machine is a device that uses an injection molding mold to make plastic products of various shapes from thermoplastics or thermosetting materials. It uses the plasticizing flow of thermosetting plastics when they are heated for the first time to quickly fill the cavity under pressure, and then produce a cross-linking reaction to solidify into a product of a certain shape and size. The injection molding machine injects the raw material into the mold through the injection head.

[0003] When an existing injection molding machine is performing injection molding, after the injection head injects the molten plastic raw material into the mold, the raw material will continue to drip due to inertia and may flow out of the injection head and drip onto the workbench, which is difficult to clean, resulting in waste of raw materials and pollution of the working environment. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose an anti-drip injection molding device. The technical problem to be solved by the utility model is: how to prevent the raw materials from continuing to drip after the injection molding is completed, so as to reduce the waste of raw materials and the pollution to the surrounding area.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A drip-proof injection molding device comprises a base and an injection molding frame arranged on the base, a slide rail is fixed on the base, a pair of mounting seats are slidably connected on the slide rail, a regulating component for controlling the two mounting seats to slide relative to each other is arranged in the slide rail, a bracket is fixed on the base, an electric push rod is fixed in the bracket, the output end of the electric push rod is fixedly connected to the injection molding frame, an injection molding nozzle is fixed on the injection molding frame, and an anti-drip component is arranged in the injection molding nozzle.

[0007] The working principle of the utility model is: the split mold can be installed on two mounting seats, and then the mounting seats are controlled to move relative to each other through the regulating component, so that the split molds can be combined into a mold as a whole, and then the injection nozzle is driven by the electric push rod to press down, so that the injection nozzle is connected to the mold as a whole to perform injection molding. When the injection molding is completed, the injection nozzle can be blocked by the anti-drip component, so as to prevent the molten plastic raw material from accumulating at the injection port, overflowing or dripping onto the workbench due to inertia.

[0008] The regulating component includes a bidirectional lead screw rotatably connected to the slide rail and a servo motor fixed in the slide rail. The output end of the servo motor is coaxially fixedly connected to the bidirectional lead screw. The threaded sections on both sides of the bidirectional lead screw are respectively threadedly connected to corresponding mounting seats.

[0009] With the above structure, the bidirectional lead screw can be driven to rotate by the servo motor. After the bidirectional lead screw rotates, it will drive the two mounting seats to move relative or oppositely. After the split mold is installed on the mounting seat, the split mold can be combined into a complete mold through this movement, so that the injection molding work can be carried out normally, and it is also convenient for the subsequent disassembly of the mold and removal of the model, thereby improving the overall efficiency.

[0010] The bottom surface of the injection nozzle is provided with an injection port, a pair of output holes are provided in the injection nozzle, the bottom ends of the two output holes are connected to the injection port, a flexible joint is fixed on the injection frame, the top ends of the two output holes are connected to the flexible joint, and an injection tube is threadedly connected to the flexible joint.

[0011] With the above structure, the injection tube can be connected through a flexible joint, and the injection tube is used to inject plastic raw materials into the injection nozzle. The plastic raw materials are input into the injection port through the output hole, and then enter the injection mold through the injection port to complete the injection work.

[0012] The anti-drip component includes a blocking block slidably connected in the injection port and a micro electric push rod fixed in the injection nozzle. The output end of the micro electric push rod is fixedly connected to the blocking block, and the blocking block blocks the bottom ends of the two output holes.

[0013] With the above structure, the output hole can be blocked by pushing the blocking block through the micro electric push rod, so as to prevent the molten plastic raw material from accumulating, overflowing or dripping onto the workbench due to inertia at the injection port.

[0014] A sealing cover is inserted into the bottom of the injection port.

[0015] With the above structure, after the injection molding is completed, the machine stops running and the sealing cover is used to seal the injection port, thereby realizing a double-layer sealing structure, improving the anti-drip effect, and preventing external dust from adhering to the injection port, maintaining the smoothness of the injection molding and preventing clogging.

[0016] Compared with the prior art, the anti-drip injection molding device has the following advantages:

[0017] 1. Use a micro electric push rod to push the blocking block to block the output hole to prevent the molten plastic raw material from accumulating, overflowing or dripping onto the workbench due to inertia at the injection port.

[0018] 2. After the injection molding is completed, the machine stops running and the sealing cover is used to seal the injection port, thereby realizing a double-layer sealing structure, improving the anti-drip effect, and preventing external dust from adhering to the injection port, maintaining the smoothness of the injection molding and preventing clogging.

[0019] 3. Install the split mold on two mounting seats, and then control the mounting seats to move relative to each other through the regulating component, so that the split molds are combined into a whole mold, so as to carry out the injection molding work normally, and also facilitate the subsequent disassembly of the mold and removal of the model, thereby improving the overall efficiency.
