Description

Technical Field

[0001] This utility model relates to the field of plastic bucket injection molding, specifically to an injection mold that prevents the bottom from collapsing. Background Technology

[0002] Plastic bucket injection molding is a processing technology that manufactures plastic buckets using injection molding. Its core is to inject molten thermoplastic into a specific mold, which then cools and solidifies to form a bucket-shaped container. The plastic bucket injection molding process involves the use of injection molds, which are precision tools used for mass production of plastic products. Made of high-strength steel, the injection mold forms a molding space through a closed cavity and core, into which molten plastic is injected under high pressure, and after cooling and solidification, it forms a plastic part of a specific shape.

[0003] However, current injection molds still have some shortcomings. Existing injection molds have not fully considered the anti-collapse structure. During the injection molding process of plastic buckets, if the anti-collapse structure of the injection mold is not fully considered, the bottom of the injection mold may collapse, which will seriously affect the service life of the injection mold, greatly increase the subsequent maintenance cost, cause certain economic losses, and make it inconvenient for workers to use the injection mold. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold that prevents bottom collapse, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-collapse injection mold, comprising a mold shell, a fixing frame, and a mold cover. Support blocks are fixedly connected to the four bottom corners of the mold shell, and anti-slip pads are fixedly adhered to the bottom of the support blocks. Reinforcing ribs are provided on the inner bottom of the mold shell. The fixing frame is fixedly connected to the outside of the mold shell, and support members are welded to both sides of the fixing frame. A support frame is fixedly connected above the support members. The mold cover is located above the mold shell, and lifting components are provided on both sides of the mold cover. The lifting components include a drive motor, a limit screw, a first lifting component, a connecting component, a second lifting component, a fixed upright plate, a rotating component, and an arc-shaped block.

[0006] Furthermore, holes are provided at the four corners of the fixing frame, and the fixing frame is fixedly connected to the discharge pipe through the holes.

[0007] Furthermore, a locking frame is welded to the top of the mold shell, and the mold shell is locked to the bottom edge of the mold cover via the locking frame.

[0008] Furthermore, there are two drive motors, which are respectively arranged on the top of the support frame and are symmetrically arranged on the left and right sides. The output shaft of the drive motor is fixedly connected to the limit screw through a coupling.

[0009] Furthermore, the top end of the limiting screw is rotatably connected to the support frame, and the bottom end of the limiting screw is rotatably connected to the support member. The outer side of the limiting screw is rotatably connected to the first lifting member by a thread.

[0010] Furthermore, connecting parts are welded to both sides of the first lifting member, and a second lifting member is welded to the other end of the connecting parts, and the side walls of both the first and second lifting members are in contact with the inner side wall of the support frame.

[0011] Furthermore, a fixed upright plate is connected through the center of the second lifting component, and the fixed upright plate is located inside the support frame, with the ends of the fixed upright plate welded to the support component and the support frame respectively.

[0012] Furthermore, both the first and second lifting components are rotatably connected to rotating components on their sides, and an arc-shaped block is rotatably connected to one side of the rotating component, and the arc-shaped block is fixedly connected to the side of the mold cover.

[0013] This utility model provides an injection mold that prevents bottom collapse, which has the following beneficial effects:

[0014] 1. This utility model is equipped with reinforcing ribs. During the injection molding process of plastic buckets, reinforcing ribs are set at the inner bottom of the mold shell to ensure the quality of the injection mold, prevent the bottom from collapsing due to excessive external extrusion pressure, ensure the smooth molding of the injection material inside the mold, reduce subsequent maintenance costs, avoid certain economic losses, protect the injection mold, extend the service life of the injection mold, and facilitate the use of the injection mold by the staff.

[0015] 2. This utility model is equipped with a lifting component. During the injection molding process of plastic buckets, the rotation of the limiting screw causes the first lifting component and the second lifting component connected to both sides via connecting parts to move up and down. This causes the mold cover, which is fixedly connected to the arc block on the sides of the first and second lifting components, to move up and down accordingly. This automated process avoids manual top squeezing of the injection mold, reduces the workload of workers, improves the efficiency of molding the injection material inside the injection mold, and facilitates the use of the injection mold by workers.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-4 As shown, an anti-collapse injection mold includes a mold shell 1, a fixing frame 4, and a mold cover 8. Support blocks 2 are fixedly connected to the four bottom corners of the mold shell 1, and anti-slip pads are fixedly adhered to the bottom of the support blocks 2. Reinforcing ribs 3 are provided on the inner bottom of the mold shell 1. The fixing frame 4 is fixedly connected to the outside of the mold shell 1. Holes are opened at the four corners of the fixing frame 4, and discharge pipes 5 are fixedly connected to the fixing frame 4 through the holes. Support members 6 are welded to both sides of the fixing frame 4, and a support frame 7 is fixedly connected to the top of the support members 6.

[0023] The specific operation is as follows: the anti-slip pads fixedly attached to the bottom of the four corner support blocks 2 at the bottom of the mold shell 1 ensure the stability of the mold shell 1. During the subsequent injection molding process, the reinforcing ribs 3 set at the bottom of the mold shell 1 ensure the quality of the injection mold and prevent the bottom from collapsing. The fixed frame 4 fixedly connected to the outside of the mold shell 1 collects the overflowing injection material, which can then flow into the holes opened at the four corners of the fixed frame 4 and then be discharged from the discharge pipes 5 fixed at the bottom of the four corners of the fixed frame 4, making it convenient for the staff to use the injection mold.

[0024] like Figures 1-4As shown, the mold cover 8 is positioned above the mold shell 1. A locking frame 9 is welded to the top of the mold shell 1, and the mold shell 1 is locked to the bottom edge of the mold cover 8 via the locking frame 9. Lifting components 10 are provided on both sides of the mold cover 8. Each lifting component 10 includes a drive motor 1001, a limiting screw 1002, a first lifting element 1003, a connecting element 1004, a second lifting element 1005, a fixed upright plate 1006, a rotating element 1007, and an arc-shaped block 1008. There are two drive motors 1001, each positioned on the top of the support frame 7, symmetrically arranged. The output shaft of each drive motor 1001 is fixedly connected to the limiting screw 1002 via a coupling. The top end of the limiting screw 1002 is rotatably connected to the support frame 7, and the bottom end of the limiting screw 1002 is connected to... The support member 6 is rotatably connected, and the outer side of the limiting screw 1002 is rotatably connected to the first lifting member 1003 by a thread. The two sides of the first lifting member 1003 are welded with connecting members 1004, and the other end of the connecting member 1004 is welded with the second lifting member 1005. The side walls of the first lifting member 1003 and the second lifting member 1005 are in contact with the inner side wall of the support frame 7. The center of the second lifting member 1005 is connected through a fixed plate 1006, and the fixed plate 1006 is located inside the support frame 7. The ends of the fixed plate 1006 are welded to the support member 6 and the support frame 7 respectively. The sides of the first lifting member 1003 and the second lifting member 1005 are rotatably connected with rotating members 1007, and one side of the rotating member 1007 is rotatably connected with an arc block 1008. The arc block 1008 is fixedly connected to the side of the mold cover 8.

[0025] The specific operation is as follows: the lifting assembly 10 can be used to lift the mold cover 8. Under the control of the external PLC controller, the drive motors 1001 on both sides operate synchronously. The drive motors 1001 drive the limit screw 1002 to rotate, causing the first lifting member 1003, which is connected to the first lifting member 1003 by a threaded rotation, to move. The second lifting member 1005, which is connected to the first lifting member 1003 by a connecting member 1004, moves through the outside of the fixed plate 1006. The sides of the first lifting member 1003 and the second lifting member 1005 are fixedly connected to the arc block 1008. The mold cover 8 then moves up and down accordingly. In addition, the first lifting component 1003 and the second lifting component 1005 are rotatably connected to the arc block 1008 through the rotating component 1007, which has a certain fault tolerance range to ensure the smooth lifting and lowering of the mold cover 8. As the mold cover 8 continues to descend, the bottom edge of the mold cover 8 gradually engages with the locking frame 9 welded to the top of the mold shell 1, thereby extruding and molding the injection mold. As the mold cover 8 continues to rise, the mold cover 8 separates from the top of the mold shell 1, thereby facilitating the demolding process of the injection mold and making it convenient for the staff to use the injection mold.

[0026] In summary, this anti-collapse injection mold, according to Figures 1-4 The structure shown illustrates that during the injection molding process of a plastic bucket, the mold is first stabilized by anti-slip pads fixed to the bottom of the four corner support blocks 2 at the bottom of the mold shell 1. During subsequent injection molding, the reinforcing ribs 3 at the bottom of the mold shell 1 ensure the quality of the injection mold and prevent collapse. The fixed frame 4, fixedly connected to the outside of the mold shell 1, collects any overflowing injection material, which then flows into the holes at the four corners of the fixed frame 4 and is discharged through the discharge pipes 5 fixed at the bottom of the four corners. The lifting assembly 10 can be used to raise and lower the mold cover 8. Under the control of an external PLC controller, the drive motors 1001 on both sides operate synchronously. The drive motors 1001 drive the limit screw 1002 to rotate, causing the first lifting component 1003, which is connected to the outside of the limit screw 1002 via a threaded connection, to rotate. The movement causes the second lifting member 1005, which is connected to the first lifting member 1003 via the connecting member 1004, to move through the outside of the fixed upright plate 1006. The mold cover 8, which is fixedly connected to the arc block 1008 on the sides of the first lifting member 1003 and the second lifting member 1005, moves up and down accordingly. In addition, the first lifting member 1003 and the second lifting member 1005 are rotatably connected to the arc block 1008 via the rotating member 1007, which has a certain fault tolerance range to ensure the smooth lifting of the mold cover 8. As the mold cover 8 continues to descend, the bottom edge of the mold cover 8 gradually engages with the locking frame 9 welded to the top of the mold shell 1, thereby extruding and molding the injection mold. As the mold cover 8 continues to rise, the mold cover 8 separates from the top of the mold shell 1, thereby facilitating the demolding process of the injection mold and making it convenient for the staff to use the injection mold.
