Description

Technical Field

[0001] The present invention relates to the fields of plastic part injection molding and waste recycling, and specifically to an injection molding machine capable of quickly trimming edges. Background Art

[0002] An injection molding machine is a device commonly used for manufacturing plastic products. It heats plastic raw materials to a molten state and then injects them into a mold under high pressure. After cooling and solidification, plastic parts of a predetermined shape are obtained.

[0003] The injection molding machine mainly consists of an injection unit, a mold clamping unit, a hydraulic system, and a control system. According to the different plastic products to be processed, the mold can be disassembled and replaced. When the injection unit of the injection molding machine is working, the plastic is in a molten state and flows through the channel into the mold cavity. The molten plastic in the channel is usually called the sprue after cooling and solidification. That is, when the injection molding machine performs one mold clamping operation, it is usually accompanied by multiple plastic parts, and there are sprue connections between the multiple plastic parts. This plastic sprue usually needs to be cut off manually by workers or with the help of special sprue removal equipment. After the sprue of the injection molded part is cut off, the sprue, which is waste plastic, can be recycled.

[0004] For the work of removing the sprue of injection molded parts, manual removal is usually for some injection molded parts with complex sprue structures. Just use a special scissors to cut the connection between the plastic part and the sprue. For an injection molding machine equipped with a quick sprue cutter, there is usually a corresponding sprue cutting device inside or on one side of the injection molding machine. The injection molded part in the mold is directly clamped and transferred to the sprue cutting device by the feeding robotic arm of the injection molding machine. The injection molded part is fixed jointly by the tooling fixture at the end of the robotic arm and the sprue cutting device, and then the automatic cutter cuts the connection between the plastic part and the sprue. The plastic parts are collected, and the sprue waste is clamped and transferred to the waste bin by the robotic arm. When such equipment is working, after the injection molded part is trimmed, the sprue waste often needs to be transferred by the robotic arm, resulting in low work efficiency. If the plastic part and the sprue waste are automatically separated after the sprue cutting device cuts the injection molded part, it will help improve the overall production efficiency.

[0042] In the above embodiment, specifically, please refer to Figure 10 The shearing mechanism 7 includes a connecting frame 71 connected to the output end of the telescopic assembly 6. An installation plate 72 is provided at the bottom of the connecting frame 71. By providing the connecting frame 71 and the installation plate 72, the cutting knife 73, the first pressing assembly 74 and the second pressing assembly 75 can be installed.

A third spring 742 is sleeved outside the second fixing rod 741. An installation seat 743 is provided at the bottom of the second fixing rod 741. A pressing rod 744 is installed at the bottom of the installation seat 743. The pressing rod 744 is matched with the fitting groove 34. The first pressing assembly 74 is used to press the part of the water inlet of the injection molded part to be cut off, and locally press it from the part of the water inlet of the injection molded part to be cut off, which can improve the pressing effect.

[0045] In the above embodiment, specifically, please refer to Figure 12, the second pressing assembly 75 includes a sleeve 751 installed on the side of the mounting base 743, and a fourth spring 752 is arranged inside the sleeve 751. A third fixing rod 753 is movably installed inside the sleeve 751, and a pressing block 754 is arranged at the end of the third fixing rod 753. The pressing block 754 matches the diameter of the main rod part of the injection molded part sprue. By setting the second pressing assembly 75, it is used to press the main rod part of the injection molded part sprue to prevent the main rod part in the middle from being stressed and warped during the sprue cutting process.

[0046] In the above embodiment, specifically, please refer to Figure 10 , two groups of mounting plates 72 are arranged at the bottom of the connecting frame 71, and the two groups of mounting plates 72 are symmetrically arranged. Multiple groups of cutting knives 73, first pressing assemblies 74 and second pressing assemblies 75 are arranged at the bottoms of the two groups of mounting plates 72. The cutting knives 73, first pressing assemblies 74 and second pressing assemblies 75 at the bottoms of the two groups of mounting plates 72 are also symmetrically arranged. By setting multiple groups of cutting knives 73, first pressing assemblies 74 and second pressing assemblies 75, multiple sprue positions of the injection molded part can be cut and pressed simultaneously.

[0047] In the above embodiment, specifically, please refer to Figure 1 , a robotic arm is arranged on one side of the injection molding device 1 (the robotic arm is a prior art and is not shown in the drawings and will not be elaborated too much in this application). The robotic arm is used to clamp and transfer the injection molded part processed by the injection molding device 1 in the closed mold state to the fixing mechanism 3. By setting the robotic arm, the robotic arm can be used to drive the fixture tooling to clamp and transfer the injection molded part processed by the injection molding device 1 in the closed mold state to the fixing mechanism 3, so as to facilitate the subsequent sprue removal work.

[0048] When the present invention is working specifically: start the electromagnet assembly 4, and use the adsorption effect of the electromagnet assembly 4 to make the two movable frames 32 approach each other, which will compress the first spring 313 until the movable frame 32 touches the outer wall of the sleeve 312 and cannot move. Then, the two movable frames 32 approaching each other drive the two opposite first receiving blocks 33 to approach each other, and the two opposite receiving assemblies 35 will approach and fit. When the injection molding device 1 performs closed mold processing to form an injection molded part, start the robotic arm to control the fixture tooling at the end, clamp and transfer the injection molded part to the fixing mechanism 3, so that the main rod part of the injection molded part sprue is engaged into the second receiving block 351, and the part of the injection molded part sprue to be cut is engaged into the fitting groove 34 of the first receiving block 33. At this time, since the two first receiving blocks 33 approach each other, there is a certain gap when the first receiving block 33 and the injection molded part are engaged, making it easier to place the injection molded part into the fixing mechanism 3 and improving the fault tolerance rate of the equipment operation.

[0049] When the injection molded part is loaded by the robotic arm and completed, the robotic arm releases the injection molded part and moves away, then the electromagnet assembly 4 is turned off. The two sets of movable frames 32 move away from each other under the reset action of the first spring 313, and then the first receiving blocks 33 move away from each other, thereby applying two sets of horizontally opposite forces to the injection molded part to achieve tensioning of the injection molded part. Tightening it can improve the stability of the material during gate trimming. When the two sets of opposite receiving components 35 move away from each other, their second receiving blocks 351 move away from each other, while the movable blocks 354 inside the two sets of opposite receiving components 35 still remain in contact under the reset action of the second spring 353, thereby supporting the main rod portion of the gate of the injection molded part.

[0050] Next, start the telescopic assembly 6 to push the shearing mechanism 7 to descend as a whole. The overall descent of the shearing mechanism 7 causes the cutter 73, the first pressing assembly 74, and the second pressing assembly 75 to descend synchronously. When the cutter 73 has not yet contacted the part of the gate of the injection molded part to be cut off, the pressing rod 744 of the first pressing assembly 74 will first press the position of the gate of the injection molded part to be cut off, and the pressing block 754 of the second pressing assembly 75 will press the main rod portion of the gate of the injection molded part. As the mounting plate 72 drives the cutter 73 to continue to descend, it will apply pressure to the pressing rod 744 and the pressing block 754 by compressing the third spring 742 and the fourth spring 752, so that it can better press the injection molded part and improve the stability during the shearing process. Then the cutter 73 performs the work of trimming and cutting off the gate of the injection molded part. After the gate is cut off, the shearing mechanism 7 rises. The cut plastic parts fall into the two sets of first discharge ports 202 respectively, and then are collected by the material collection box. When the movable frames 32 are no longer restricted by the plastic parts, the two sets of movable frames 32 will move away from each other to the maximum distance under the reset action of the first spring 313, and at the same time drive the receiving components 35 to move away from each other. Then the waste generated by trimming the gate of the injection molded part will directly fall into the second discharge port 203 from between the two sets of movable frames 32. The bottom of the second discharge port 203 is connected to a waste collection box.
