[0021] 2. By setting the outer side of the mold body as an inclined plane and arranging a support component on one side of the top of the inclined plane, and one end of the support plate is also provided with an inclined plane corresponding to the mold body, it can be made that the support plate fits more closely with the mold body under the drive of the electric push rod, and the material overflowing during injection molding can be flowed onto the support plate to the greatest extent.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment

[0033] As Figures 1-8 shown, a plastic material forming mold with a trimming function includes a lower mold base 1. The upper mold base 3 is movably connected above the lower mold base 1 through a guide rod 2. A mold body 4 is fixedly installed inside the lower mold base 1. Mounting grooves 11 are respectively provided around the inner wall of the lower mold base 1. Support assemblies 5 are respectively arranged inside the mounting grooves 11. A support frame 8 is movably arranged between the mold body 4 and the inner wall of the lower mold base 1 and on the upper surface of the lower mold base 1. A waste slot 6 is fixedly installed on the outer peripheral surface of the lower end of the mold body 4 and on the upper surface of the inner wall of the lower mold base 1. The waste slot 6 is located between the mold body 4 and the support frame 8. A trimming assembly 7 is arranged on the upper surface of the support frame 8;

[0034] The support assembly 5 includes a support plate 501, and the support plate 501 is in contact with the outer peripheral surface of the mold body 4;

[0035] The trimming component 7 includes a fixed block 701 and a cutting and grinding member 709. The fixed block 701 is fixedly connected to the upper surface of the support frame 8, and a cutting knife 7099 and a grinding roller 7096 are arranged inside the cutting and grinding member 709.

[0036] Through the above technical solution, by arranging support components 5 on the outer side surfaces of the mold body 4, when injection molding is carried out, the molten plastic material can overflow onto the support components 5, and then the overflowed corner materials are cooled. Subsequently, the support components 5 are moved into the lower mold base 1, the trimming component 7 is moved upward by the support frame 8, and the mold body 4 is trimmed and polished by the cutting and grinding member 709 in the trimming component 7. The trimmed waste materials fall into the waste material groove 6 along the outer peripheral surface of the mold body 4. It should be noted that the outer side surfaces of the mold body 4 are equal and there are inclined planes at the top. One side at the top of the inclined plane is attached to the support component 5, which can maximize the flow of the material overflowed during injection molding onto the support component 5, facilitating the operation of the cutting and grinding member 709. The inner side of the waste material groove 6 is attached to the outer side surface at the lower end of the mold body 4, and the waste material groove 6 can be disassembled at will, facilitating discharging. By arranging the trimming component 7, the corner materials can be cut first and then the edges of the product can be polished, improving the product quality, and at the same time improving the processing efficiency and reducing the labor cost.

[0037] In this embodiment, limiting rods 12 and a third lead screw 9 are movably connected to the four corners of the support frame 8. The limiting rods 12 and the third lead screw 9 are respectively arranged on two diagonal lines of the support frame 8. The bottom end of the third lead screw 9 is rotatably connected to a fourth motor 10, and the fourth motor 10 and the bottom ends of the limiting rods 12 are fixedly installed on the upper surface of the inner wall of the lower mold base 1.

[0038] When specifically setting, the fourth motor 10 is started to drive the third lead screw 9 to rotate, thereby driving the support frame 8 to rise or fall. The support frame 8 is threadedly connected to the third lead screw 9 and slidably connected to the limiting rods 12. By arranging the support frame 8, the trimming component 7 can be driven to rise or fall, facilitating the trimming operation.

[0039] In this embodiment, the support component 5 further includes an electric push rod 502, a water pipe 503, and a connection groove 504. Two electric push rods 502 are fixedly connected to one side of the support plate 501. The ends of the electric push rods 502 away from the support plate 501 are fixedly installed on one side of the inner wall of the installation groove 11. A water pipe 503 is arranged through the inside of the support plate 501, and connection grooves 504 are respectively opened on both sides of the support plate 501.

[0040] During specific setting, connection grooves 504 are provided on both sides of two parallel support plates 501, and corresponding bumps are provided on both sides of the other two support plates 501, facilitating the snap connection between the support plates 501. In addition, inclined cutting surfaces corresponding to the mold body 4 are provided at one ends of the support plates 501 close to the mold body 4, so that the two can be closely attached to avoid the inflow of materials into the gaps. Both ends of the water pipe 503 are connected to the water inlet and outlet of the cooler, and cooling water flow is circulated through to accelerate the cooling of the scraps and facilitate the trimming operation quickly.

[0041] Start the electric push rod 502, and the electric push rod 502 pushes the support plate 501 to move towards the direction close to the mold body 4 until it fits against the outer surface of the mold body 4. When injection molding is carried out, the molten plastic material enters the mold body 4 and is extruded and formed by the upper mold base 3 and the mold body 4. The excess material is extruded onto the upper surface of the support plate 501. When the scraps are cooled by the water pipe 503, then the support plate 501 is moved into the installation groove 11 by the electric push rod 502 until it completely enters the installation groove 11.

[0042] In this embodiment, a first lead screw 706 is movably arranged in the fixed block 701. One end of the first lead screw 706 is rotatably connected to the inner wall of the fixed block 701, and the other end of the first lead screw 706 penetrates through the fixed block 701 and a worm gear 702 is fixedly connected to the outer rod body. A worm 703 is movably connected to one side of the worm gear 702.

[0043] In this embodiment, a first motor 704 is fixedly connected to the bottom end of the worm 703. The bottom end of the first motor 704 is fixedly connected to the upper surface of the support frame 8. The first motor 704 is located on one side of the limit rod 12. A first movable block 705 is movably connected to the outer rod body of the first lead screw 706 located inside the fixed block 701.

[0044] During specific setting, the first motor 704 is arranged corresponding to the limit rod 12, and the worm 703 connected to the first motor 704 is movably connected to two worm gears 702. In the initial state, the two worm gears 702 are respectively located at one end close to and away from the grinding part 709. When the two first motors 704 are started, the worm 703 drives the worm gears 702 and the first lead screw 706 to rotate, and then drives the first movable block 705 to move.

[0045] In this embodiment, a first cavity 707 is provided inside the first movable block 705. A second motor 708 is fixedly installed inside the first cavity 707. The output end of the second motor 708 penetrates through the first movable block 705 and is fixedly connected to a cutting and grinding member 709. Among them, the second motor 708 is used to flip the cutting and grinding member 709. The cutting and grinding member 709 shrinks after cutting the scrap under the drive of the first movable block 705. The second motor 708 is started at the other end of the fixed block 701, so that the cutting and grinding member 709 rotates 180 degrees in the horizontal direction, and then grinds the edge of the mold body 4 under the drive of the first movable block 705. By setting the second motor 708 to drive the cutting and grinding member 709 to flip, the cutting and grinding device can be centrally arranged, and the cutting and grinding operations can be completed during one reciprocating movement of the first movable block 705, improving work efficiency.

[0046] In this embodiment, the cutting and grinding member 709 includes a mounting block 7091 and a second lead screw 7094. The lower surface of the mounting block 7091 is fixedly connected to the output end of the second motor 708. A second cavity 7092 is provided inside the mounting block 7091. A third motor 7093 is fixedly installed inside the second cavity 7092.

[0047] In this embodiment, the output end of the third motor 7093 penetrates through the mounting block 7091 and is fixedly connected to a second lead screw 7094. A second movable block 7095 is threadedly connected to the outer thread of the second lead screw 7094. A stopper is provided at the top of the second lead screw 7094. By setting the third motor 7093 to drive the second lead screw 7094 to rotate, the second movable block 7095 is driven to rise or fall along the direction of the second lead screw 7094, thereby changing the positions of the cutting knife 7099 and the grinding roller 7096.

[0048] In this embodiment, first support arms 7097 are respectively movably connected to the upper surface of the mounting block 7091 and on both sides of the second lead screw 7094. One ends of the first support arms 7097 far from the mounting block 7091 are respectively movably connected to a cutting knife 7099 and a grinding roller 7096. Second support arms 7098 are respectively movably connected to the outside of the cutting knife 7099 and the grinding roller 7096 on both sides of the first support arms 7097. The cutting knife 7099 and the grinding roller 7096 are both driven by motors inside and can automatically perform cutting and rotation.

[0049] In this embodiment, one ends of the second support arms 7098 on both sides far from the first support arms 7097 are respectively movably connected to the lower surface of the second movable block 7095. One side of the top of the cutting knife 7099 is in contact with the outer side surface of the mold body 4, and the shaft body of the top of the grinding roller 7096 is in contact with the inner wall of the lower mold base 1.

[0050] By movably connecting the second support arm 7098 below the second movable block 7095 and movably connecting both the second support arm 7098 and the first support arm 7097 outside the cutting knife 7099 and the grinding roller 7096, when the second movable block 7095 rises, the angle between the second support arms 7098 on both sides and the first support arm 7097 becomes larger. At the same time, the distance between the cutting knife 7099 and the grinding roller 7096 connected to the middle of the second support arm 7098 and the first support arm 7097 gradually becomes smaller and the position rises. When the second movable block 7095 descends, the angle between the second support arms 7098 on both sides and the first support arm 7097 becomes smaller, thereby driving the cutting knife 7099 and the grinding roller 7096 to move towards the inner wall of the mold body 4 or the lower die holder 1 until they fit on one side of the mold body 4 or the lower die holder 1, and then performing cutting and grinding operations on the finished product.

[0051] In the initial state, the cutting knife 7099 does not fit on one side of the mold body 4. When it is necessary to cut and grind the scrap, the fourth motor 10 and the third motor 7093 are started simultaneously, so that while the support frame 8 drives the cutting and grinding member 709 to rise, the cutting knife 7099 gradually fits on one side of the mold body 4 until it contacts the finished product. Then, the cutting knife 7099 performs cutting. The worm 703 is driven to rotate by the first motor 704, thereby driving the worm gear 702 and the first lead screw 706 to rotate, and then driving the first movable block 705 and the cutting and grinding member 709 to move, so that the cutting knife 7099 moves along the mold body 4 from one end to the other end. The cut scrap falls into the waste chute 6 along the inclined plane of the mold body 4. Subsequently, the mounting block 7091 is driven to flip by the second motor 708, so that the positions of the grinding roller 7096 and the cutting knife 7099 are interchanged. Then, the first motor 704 rotates in the reverse direction, so that the grinding roller 7096 is moved to the other end while grinding. After the grinding is completed, the above operations are repeated to return the device to its original position for the next operation.

[0052] The working principle of the plastic material forming mold with a trimming function:

[0053] During use, first start the electric push rod 502. The electric push rod 502 pushes the support plate 501 to move towards the direction close to the mold body 4 until it fits against the outer side surface of the mold body 4. When injection molding is carried out, the molten plastic material enters the mold body 4 and is extruded and formed by the upper mold base 3 and the mold body 4. The excess material is extruded onto the upper surface of the support plate 501. When the scraps are cooled by the water pipe 503, then the support plate 501 is moved into the installation groove 11 by the electric push rod 502 until it completely enters the installation groove 11. Then start the fourth motor 10. The output end of the fourth motor 10 drives the third lead screw 9 to rotate, thereby driving the support frame 8 to rise, and further driving the trimming component 7 to rise. At the same time, start the third motor 7093. The third motor 7093 drives the second lead screw 7094 to rotate, driving the second movable block 7095 to descend, so that the included angle between the two second support arms 7098 and the first support arm 7097 becomes smaller, thereby driving the cutting knife 7099 and the grinding roller 7096 to move towards the direction close to the mold body 4 or the inner wall of the lower mold base 1 until they contact the finished product. Then the cutting knife 7099 cuts. The first motor 704 drives the worm 703 to rotate, thereby driving the worm gear 702 and the first lead screw 706 to rotate, thereby driving the first movable block 705 and the cutting and grinding part 709 to move, so that the cutting knife 7099 moves along the mold body 4 from one end to the other end. The cut scraps fall into the waste material groove 6 along the inclined plane of the mold body 4. Subsequently, the third motor 7093 drives the second movable block 7095 to rise, and the included angle between the two second support arms 7098 and the first support arm 7097 becomes larger. At the same time, the distance between the cutting knife 7099 and the grinding roller 7096 connected to the middle of the second support arm 7098 and the first support arm 7097 gradually becomes smaller and the position rises. When the cutting knife 7099 is far away from the mold body 4, the second motor 708 drives the mounting block 7091 to turn over, so that the positions of the grinding roller 7096 and the cutting knife 7099 are interchanged. Then the first motor 704 rotates in the reverse direction, so that the grinding roller 7096 is moved to the other end while grinding. After the grinding is completed, repeat the above operations to return the device to its original position for the next operation.

[0055] The specific model specification of the second motor 708 is Y80M1-2;

[0056] The specific model specification of the third motor 7093 is Y100L-2;
