Description

Technical Field

[0001] The utility model relates to the technical field of rocket heads, and more particularly to a rocket head assembly with uniform feeding. Background Art

[0002] An injection molding machine is a primary molding device for molding thermoplastics or thermosetting materials into plastic products of various shapes using a plastic molding mold. Injection molding is accomplished using an injection molding machine and a mold. During operation, the injection molding machine primarily controls the flow and sealing of liquid within the injection molding machine through a rocket head. For example, prior art publication No. CN208592012U discloses a rocket head assembly for uniform feeding. The screw portion drives the rocket head and a check ring forward through a power mechanism. One side of the long pusher claw contacts the side of the long wing. The semicircular groove of the rubber ring aligns with the feed semicircular groove of the check ring, forming a glue passage. The fluid plastic enters the metering storage bin through the glue passage. During injection, the screw portion drives the rocket head and the check ring in reverse. The other side of the long pusher claw contacts the side of the short wing. The semicircular groove of the rubber ring and the feed semicircular groove of the check ring are offset, forming a seal that prevents the fluid plastic from continuing to flow into the metering storage bin.

[0003] The above device has a simple structure, is easy to install and disassemble, and can feed materials evenly. However, the injection liquid flowing inside the rubber ring will cause wear and failure during movement, thereby affecting the sealing performance of the rubber ring, making it inconvenient to maintain and replace.

DETAILED DESCRIPTION

[0023] The utility model provides a rocket head assembly with uniform feeding, such as Figure 1 and 2 As shown, it includes a rocket head body 1, a material blocking protrusion 5 is provided on the outside of one end of the rocket head body 1, a supporting connecting rod 3 is provided on the outside of one end of the rocket head body 1, and a rubber ring 2 is provided on the side of the outer end surface of the rocket head body 1 close to the material blocking protrusion 5. The outer end surface of the material blocking protrusion 5 is provided with a material guide groove 4, which can facilitate the diversion of the liquid inside the injection molding machine;

[0024] The number of the guide grooves 4 is multiple, and they are arranged in a circular array outside the center point of the rocket head body 1 in the right viewing direction. The lower side of the inner end surface of the guide groove 4 is coplanar with the outer end surface of the rocket head body 1 in the right viewing direction. The outer end surface diameter of the blocking protrusion 5 in the right viewing direction is smaller than the outer end surface diameter of the rubber ring 2 in the right viewing direction, which can facilitate the liquid inside the injection molding machine to be guided from the inside of the rubber ring 2 into the inside of the guide groove 4;

[0025] The two sides of the inner end surface of the rubber ring 2 are set in an inclined state, and one side of the outer end surface of the material blocking protrusion 5 is set in an inclined state. The inner end surface diameter of the rubber ring 2 in the right viewing direction is larger than the outer end surface diameter of the rocket head body 1 in the right viewing direction.

[0026] like Figure 3 and 4As shown, the outer end surface of the support connecting rod 3 is provided with a connecting external thread 11, and the outer end surface of the support connecting rod 3 is provided with a support stopper 7. A raised nut block 9 is fixedly provided on one end surface of the support stopper 7, which can facilitate the installation and disassembly of the support stopper 7, so that when the rubber ring 2 is damaged, it can be conveniently disassembled for maintenance and replacement. An adaptation groove 8 is opened on one side of the inner end surface of the support stopper 7, and a connecting internal thread 10 is provided on the inner end surface of the support stopper 7 on the side close to the adaptation groove 8;
