Description

Technical Field

[0001] This utility model relates to the field of mold ejection equipment technology, and in particular to an ejection mechanism for injection molding machine molds. Background Technology

[0002] This existing injection molding equipment, through the coordinated operation of a cooling mechanism and mold components, facilitates the removal of the molded parts after injection molding. The removal process is simple and does not require manual intervention, saving time and effort. Furthermore, the cooling mechanism rapidly cools the molded parts, preventing them from overheating and burning workers during handling. This also improves injection molding efficiency and brings great convenience to the injection molding process.

[0003] However, when the aforementioned injection molding equipment opens the mold components, the injection molded parts are affected by the solidification characteristics, making it easier for them to stick to the inside of the mold. As a result, when the mold is opened, the injection molded parts are not easy to loosen and tend to stick to the inside of a certain mold. They also need to be loosened and removed manually, which affects the overall material handling efficiency of the injection molded parts.

[0004] Therefore, it is essential to provide an ejection mechanism for injection molding dies to address the shortcomings of existing technologies. Utility Model Content

[0005] This utility model includes an arched support frame, a cylinder is fixedly installed on the top of the arched support frame, an upper mold base is fixedly installed on the output end of the cylinder, a guide component is installed between the upper mold base and the top of the arched support frame, a lower mold base is installed below the upper mold base, and a mold ejection component is movably installed at the bottom of the lower mold base. The mold ejection component is installed on the inner side of the arched support frame.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] An ejection mechanism for an injection molding machine mold is provided, including an arched support frame. A cylinder is fixedly installed on the top of the arched support frame, and an upper mold base is fixedly installed on the output end of the cylinder. A guide assembly is installed between the upper mold base and the top of the arched support frame. A lower mold base is fitted below the upper mold base, and a mold ejection assembly is movably installed at the bottom of the lower mold base. The mold ejection assembly is installed on the inner side of the arched support frame.

[0008] Specifically, the mold ejection assembly includes a horizontal support plate, which is horizontally installed inside the arched support frame. The upper end face of the horizontal support plate is fixedly installed with the lower end face of the lower mold base. A circular through hole is opened in the middle of the horizontal support plate. A slide rail is integrally formed on the inner wall of the circular through hole. A columnar rod is slidably connected on the slide rail. An inverted cone ejector plate is integrally formed above the columnar rod.

[0009] Preferably, a pusher groove is provided on the lower end face of the forming cavity inside the lower mold base. The lower part of the inverted cone ejector plate abuts against the pusher groove. The upper end face of the inverted cone ejector plate is connected to the lower end face of the forming cavity inside the lower mold base. The bottom of the cylindrical rod abuts against two balance plates. The bottom of the two balance plates abuts against a vibration expansion joint. One end of each of the two balance plates is hinged to a vertical support plate. The two balance plates are symmetrically installed relative to the central axis of the cylindrical rod. A base plate is fixedly installed at the bottom of the vertical support plate. The base plate is fixedly installed at the bottom of the arched support frame.

[0010] Preferably, the vibration telescopic device includes a vibration motor, an electric telescopic rod is installed at the bottom of the vibration motor, a frustum block is installed at the top of the vibration motor, a conical spring is snapped onto the outside of the frustum block, and the two sides of the conical spring abut against the balance plate respectively.

[0011] The guide assembly includes two guide rods that vertically penetrate the top of the arched support frame. The guide rods are slidably connected to the inside of the arched support frame. The bottom of the two guide rods is fixedly installed to the upper end face of the upper mold base. A positioning block is integrally formed on the top of the two guide rods. A telescopic spring is installed on the lower end face of the positioning block. The inside of the telescopic spring is movably connected to the guide rod. The bottom of the telescopic spring abuts against the upper end face of the arched support frame.

[0012] This invention uses a cylinder to control the lifting and lowering of the upper mold base. The upper and lower mold bases work together to extrude and complete the production of the injection molded part. The guide component can stably guide the lifting and lowering of the upper mold base. The vibrating telescopic device can simultaneously vibrate and lift the cylindrical rod, which in turn drives the inverted cone ejector plate, which is integrally formed with the cylindrical rod, to vibrate and lift. The inverted cone ejector plate vibrates and lifts the injection molded part between the upper and lower mold bases, making it easier for the mold ejection component to loosen and remove the injection molded part, thus improving the overall material removal efficiency of the injection molded part.

[0041] The present invention will be further described in conjunction with the following embodiments.

[0042] Example 1.

[0043] like Figure 1-3 As shown, an ejection mechanism for an injection molding machine mold includes an arched support frame 1. A cylinder 2 is fixedly installed on the top of the arched support frame 1. An upper mold base 3 is fixedly installed at the output end of the cylinder 2. A guide assembly 4 is installed between the upper mold base 3 and the top of the arched support frame 1. A lower mold base 5 is fitted below the upper mold base 3. A mold ejection assembly 6 is movably installed at the bottom of the lower mold base 5. The mold ejection assembly 6 is installed on the inner side of the arched support frame 1.

[0044] The upper mold base 3 is raised and lowered by the cylinder 2. The upper mold base 3 and the lower mold base 5 work together to extrude and complete the production of the injection molded part. The guide component 4 can stably guide the raising and lowering of the upper mold base 3. The mold ejection component 6 makes it easy for the injection molded part to loosen and not easily adhere to the inside of the molding mold. There is no need to manually loosen and remove it, which will not affect the overall material handling efficiency of the injection molded part.

[0045] like Figure 1-3 As shown, the mold ejection assembly 6 includes a horizontal support plate 7, which is horizontally installed on the inner side of the arched support frame 1. The upper end face of the horizontal support plate 7 is fixedly installed with the lower end face of the lower mold base 5. A circular through hole 8 is opened in the middle of the horizontal support plate 7. A slide rail 9 is integrally formed on the inner wall of the circular through hole 8. A columnar rod 10 is slidably connected on the slide rail 9. An inverted cone ejector plate 11 is integrally formed above the columnar rod 10.

[0046] The integrally formed cylindrical rod 10 and the inverted conical ejector plate 11 slide vertically on the circular through hole 8 of the horizontal support plate 7, which facilitates the guidance and positioning of the mold ejection assembly 6 to lift and remove the injection molded part, and facilitates the mold ejection assembly 6 to loosen and remove the injection molded part, thereby improving the overall material removal efficiency of the injection molded part.

[0047] like Figure 1-3 As shown, a pusher groove 12 is provided on the lower end face of the forming cavity inside the lower mold base 5. The lower part of the inverted cone ejector plate 11 abuts against the pusher groove 12. The upper end face of the inverted cone ejector plate 11 is connected to the lower end face of the forming cavity inside the lower mold base 5 to close the lower end face of the forming cavity. The bottom of the column rod 10 abuts against two balance plates 13. The bottom of the two balance plates 13 abuts against a vibration expansion joint 14. One end of each of the two balance plates 13 is hinged to a vertical support plate 15. The two balance plates 13 are symmetrically installed relative to the central axis of the column rod 10. A base plate 16 is fixedly installed at the bottom of the vertical support plate 15. The base plate 16 is fixedly installed at the bottom of the arch support frame 1.

[0048] The vibratory telescopic device 14 can simultaneously vibrate and raise the cylindrical rod 10, further driving the inverted cone ejector plate 11, which is integrally formed with the cylindrical rod 10, to vibrate and raise. The inverted cone ejector plate 11 vibrates and lifts the injection molded part between the upper mold base 3 and the lower mold base 5, making it easier for the mold ejector assembly 6 to loosen and remove the injection molded part, thus improving the overall material removal efficiency of the injection molded part.

[0049] like Figure 1-3 As shown, the vibration telescopic device 14 includes a vibration motor 17, an electric telescopic rod 18 is installed at the bottom of the vibration motor 17, a frustum block 19 is installed at the top of the vibration motor 17, a conical spring 20 is snapped onto the outside of the frustum block 19, and the two sides of the conical spring 20 abut against the balance plate 13 respectively.

[0050] When the vibration motor 17 and the electric telescopic rod 18 are turned on, the frustum block 19 can be vibrated and lifted. Since the two balance plates 13 are respectively abutted on both sides of the frustum block 19 with the conical spring 20, the two balance plates 13 can be vibrated and lifted at the same time. The two balance plates 13 form a relatively balanced and stable triangular lifting structure, which improves the stability of the injection molded part being vibrated and lifted by the mold ejection assembly 6.

[0051] like Figure 1-3 As shown, the guide assembly 4 includes two guide rods 21, which vertically penetrate the top of the arched support frame 1. The guide rods 21 are slidably connected to the inside of the arched support frame 1. The bottom of the two guide rods 21 is fixedly installed on the upper end face of the upper mold base 3. The top of the two guide rods 21 is integrally formed with a positioning block 22. A telescopic spring 23 is installed on the lower end face of the positioning block 22. The inner side of the telescopic spring 23 is movably connected to the guide rod 21. The bottom of the telescopic spring 23 abuts against the upper end face of the arched support frame 1.

[0052] The guide component 4 can guide and position the upper mold base 3, thereby improving the stability of the upper mold base 3 during the lifting and lowering process.

[0053] This utility model includes an arched support frame 1, with a cylinder 2 fixedly installed on the top of the arched support frame 1. An upper mold base 3 is fixedly installed at the output end of the cylinder 2. A guide component 4 is installed between the upper mold base 3 and the top of the arched support frame 1. A lower mold base 5 is installed below the upper mold base 3. A mold ejection component 6 is movably installed at the bottom of the lower mold base 5. The mold ejection component 6 is installed on the inner side of the arched support frame 1. The cylinder 2 controls the lifting and lowering of the upper mold base 3. The upper mold base 3 and the lower mold base 5 work together to extrude and complete the production of the injection molded part. The guide component 4 can stably guide the lifting and lowering of the upper mold base 3. The vibrating telescopic device 14 can simultaneously vibrate and lift the cylindrical rod 10, further driving the inverted cone ejector plate 11, which is integrally formed with the cylindrical rod 10, to vibrate and lift. The inverted cone ejector plate 11 vibrates and lifts the injection molded part between the upper mold base 3 and the lower mold base 5, making it convenient for the mold ejection component 6 to loosen and remove the injection molded part, thus improving the overall material removal efficiency of the injection molded part.
