Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for a handle seat. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. The handle seat is the connecting part of some tool box handles, usually a long strip structure, and usually requires the use of an injection mold for production.

[0003] When the existing injection mold is used to injection mold the handle seat, in order to inject the opening of the handle seat, a metal rod needs to be inserted into the reserved position in the mold to form a through hole, which is convenient for connection with other components. When openings of different diameters need to be injection molded, the mold core mostly needs to be replaced, and the operation is relatively cumbersome, which increases the operating steps and labor of the workers, affects the work efficiency, and needs further improvement. For this reason, we propose a handle seat injection mold. Utility Model Content

[0023] As Figures 1 - 4 shown, the handle seat injection mold includes a lower mold 1. An injection groove 3 is opened in the middle of the upper end of the lower mold 1. Two connection holes 10 are symmetrically distributed left and right at the front end of the lower mold 1. Connecting rods 7 are movably sleeved inside both of the two connection holes 10. Opening components 9 are installed at the rear ends of both of the two connecting rods 7. The opening components 9 are located in the injection groove 3. A cross plate 5 is movably sleeved on the outer surfaces of both of the two connecting rods 7. A fixing component 6 is installed at the front end of the cross plate 5.

[0024] In order to be able to inject openings of different sizes, by providing detachable opening components 9, it is convenient to inject openings of different diameters without replacing the mold core. The operation is simple, reducing the operation steps and labor intensity of workers, improving the work efficiency, and increasing the installation range of the handle seat. The opening component 9 includes a guide post 91. The guide post 91 is arranged at the front end of the connecting rod 7. A circular groove 92 is opened at the front end of the guide post 91. A screw rod 93 is arranged in the circular groove 92. The rear end of the screw rod 93 is threadedly inserted into the connecting rod 7.

[0025] The fixing component 6 is used to facilitate the disassembly of the connecting rod 7, which is convenient for replacing the opening component 9 subsequently, providing convenience for workers and further improving the replacement efficiency. The fixing component 6 includes a first vertical plate 61, and the first vertical plate 61 is installed in the middle of the front end of the cross plate 5. The first vertical plate 61 and the second vertical plate 65 are installed on the cross plate 5 through bolts. The left end and the right end of the first vertical plate 61 are both installed with telescopic rods 62. The outer surfaces of the two telescopic rods 62 are both movably sleeved with springs 63. The telescopic rods 62 are used to guide the springs 63. The mutually remote ends of the two telescopic rods 62 are both installed with fixing rods 64. The outer surfaces of the two fixing rods 64 are both movably sleeved with second vertical plates 65, and the second vertical plates 65 are installed on the cross plate 5.

[0026] Fixing holes 8 are formed on the outer surfaces of the two connecting rods 7. When the mutually remote ends of the two fixing rods 64 respectively extend into the two fixing holes 8, the connecting rod 7 cannot be detached from the connection hole 10.

[0027] The mutually close ends of the two springs 63 are both fixedly connected to the first vertical plate 61, and the mutually remote ends of the two springs 63 are respectively fixedly connected to the two fixing rods 64.

[0028] A cylinder 4 is installed in the middle of the front end of the lower mold 1. The conveying end of the cylinder 4 is fixedly connected to the cross plate 5. The cylinder 4 is used to drive the opening component 9 to move through the cross plate 5, so that the opening component 9 moves away from the injection molding groove 3, facilitating subsequent demolding. An upper mold 2 is arranged on the upper side of the lower mold 1.

[0029] For the handle seat injection mold proposed by the present utility model, when the opening diameter of the handle seat needs to be adjusted, pull the two fixing rods 64 to make them respectively away from the two fixing holes 8, then the connecting rod 7 can be taken out from the connection hole 10, and the opening component 9 can be taken out from the injection molding groove 3. Rotate the screw 93 to disassemble the guide post 91, and then install other diameter guide posts 91 at the front end of the connecting rod 7 and fix them with the screw 93, then the replacement can be completed, enabling the mold to inject openings of different sizes and meet different size requirements. After that, pull the fixing rod 64, insert the connecting rod 7 into the connection hole 10, make the opening component 9 abut against the inner wall of the injection molding groove 3, and release the fixing rod 64 to make the fixing rod 64 insert into the fixing hole 8, then the adjustment can be completed, which is convenient for injecting handle seats with different apertures.
