Description

Novel injection mold

Technical Field

The utility model relates to the technical field of injection molds, in particular to a novel injection mold.

Background

As is well known, an injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification.

After the injection mold is demolded, the injection port of the injection mold protrudes a part due to the fact that the injection mold needs to be injected through the injection port, and the injection port of the obtained product needs to be reprocessed, so that the injection mold is not smooth and has obvious protrusion.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the novel injection mold of the utility model comprises a mold body 1, an injection port 2 is arranged at the top end of the mold body 1, an injection port 2 treatment device is arranged at the position of the injection port 2, the injection port 2 treatment device comprises a treatment tank 3, the treatment tank 3 is arranged at the right end of the injection port 2, sliding grooves 4 are arranged at the front end and the rear end of the treatment tank 3, the left end of the sliding groove 4 extends leftwards and is connected with the injection port 2, a scraper is arranged in the treatment tank 3 and comprises a push plate 5, the push plate 5 is obliquely arranged, a cutter head 6 is arranged at the bottom end of the left end of the push plate 5, sliding blocks 7 are arranged at the front end and the rear end of the left end of the push plate 5, a sliding rod 9 is connected to the right end of the push plate 5 through a fixed block 8, the sliding blocks 7 and the sliding rods 9 are matched with the sliding grooves 4 and are in sliding connection, and a spring 10 is arranged at the right end of the sliding blocks 7 and the treatment tank 3.

It should be further specifically noted that the right portion of the sliding groove 4 is disposed in an upward curved shape, the processing groove 3 is not directly communicated with the injection molding cavity of the mold body 1, and is disposed in a curved shape, so that the push plate 5 can be disposed in the processing cavity, the tool bit 6 is rotatably connected with the push plate 5, and a coil spring 11 is disposed between the middle portion of the bottom end of the tool bit 6 and the push plate 5, when the push plate 5 moves rightwards, since the right portion of the sliding groove 4 is disposed in an arc shape, the tool bit 6 can rotate, so that a large end enters the processing groove 3, when the push plate 5 is pushed out by a spring 10, the tool bit 6 slides into the injection molding port 2, the tool bit 6 can rotate downwards under the pulling of the coil spring 11, so that the tool bit 6 removes redundant plastic, the bottom end of the tool bit 6 is flush with the bottom end of the injection molding port 2, so that the processing of the tool bit 6 is more beautiful, the processing effect is better, and the push plate 5 is made of a low-friction material, when moulding plastics, owing to will mould plastics the pipe and stretch into in the mouth 2 of moulding plastics, mould plastics the pipe this moment and press push pedal 5, because push pedal 5 sets up for the slope, can let push pedal 5 move rightwards to extrude push pedal 5, the inclination of push pedal 5 must not be less than 25 degrees, and the hard that makes when moulding plastics the pipe and promote push pedal 5 is littleer, and the cooperation mode between slider 7 and slide bar 9 and spout 4 is clearance fit, can reduce the frictional resistance between slide bar 9, slider 7 and the spout 4.
