Description

Technical Field

[0001] The invention relates to the field of mechanical design, in particular to a multi-directional spraying and pouring head. Background Art

[0002] Casting molding is a common production process, which includes the casting molding of shoe body parts, such as soles, uppers, etc., and the casting molding of shoe body parts is usually performed by pouring the required shoe materials, such as PU materials or mixed materials (such as a mixture obtained by mixing material A and material B, wherein material A is polyethylene adipate, polypropylene adipate, polybutylene adipate or polyethylene adipate, and material B is isocyanate) into a molding mold, and the above-mentioned shoe materials are foamed and molded into corresponding shoe body parts by heating and maintaining pressure. The casting molding process usually relies on the implementation of a casting machine, and in order to facilitate the effective pouring of the raw materials into the molding mold, a casting head is usually provided at the raw material outlet of the casting machine.

[0003] However, a common pouring machine pouring head is usually only equipped with a cylindrical stirring body, which can only play a certain stirring role. On the one hand, when it is used for pouring raw materials, it mainly relies on the pressure of the raw materials when they flow to the pouring head. It cannot pressurize the raw materials by itself, which may lead to insufficient pressure of the raw materials during pouring, and the raw materials cannot be effectively dispersed when poured into the mold. The raw materials will contain more air, which will eventually lead to more pores in the finished product. On the other hand, since the pouring head of the conventional pouring machine is facing downward, for the side of the finished product that needs to be poured, especially the high and thin side, such as the side of the sole, it can only be poured to the above position when the pouring machine head makes corresponding movements to change the direction of the pouring head, which increases the processing difficulty and reduces the processing efficiency. Summary of the invention

[0004] The object of the present invention is to provide a multi-directional spray pouring head which can solve one or more of the above problems.

[0005] According to one aspect of the present invention, there is provided a multi-directional spray pouring head, comprising a shell, a rotating shaft and a spray block, wherein the rotating shaft is provided with a stirring end and a boosting end, the shell is provided with a stirring chamber, a boosting chamber and a discharge chamber, the stirring chamber, the boosting chamber and the discharge chamber are sequentially connected, the rotating shaft is arranged in the shell, the stirring chamber is arranged at the periphery of the stirring end, the boosting chamber is arranged at the periphery of the boosting end, the spray block is connected to the rotating shaft, the discharge chamber is arranged at the periphery of the spray block, and a plurality of spray chambers are enclosed together with the spray block.

[0006] The beneficial effects of the present invention are as follows: in the present invention, the raw material can flow through the stirring chamber and the boosting chamber and then enter the spraying chamber and flow out; and when the rotating shaft rotates, the raw material in the stirring chamber can be stirred by the stirring end, and the raw material in the boosting chamber can be pressurized by the boosting end, thereby ensuring that the raw material at the pouring point of the spraying chamber can be fully stirred and poured out with sufficient pouring pressure, so that it can be effectively dispersed when poured into the mold, so as to reduce the pores contained therein and improve the quality of the finished product; and the present invention, by setting a spraying block, can prevent the raw material from being blocked by the spraying block when entering the discharge chamber, and turn to spraying from the spraying chamber, that is, flowing out in a spraying shape from the side of the spraying block, thereby realizing multi-directional spraying; therefore, in addition to being able to spray on the bottom of the mold, the present invention can also effectively spray on the side of the mold, so that the side of the finished product, especially the high and thin side, can be fully formed; and because its spraying does not require the casting machine head to swing and other actions, it can effectively improve the efficiency of the casting process and has strong practicality.

[0007] In some embodiments, the cross-sectional area of ​​the stirring chamber is larger than the cross-sectional area of ​​the boosting chamber, and a transition chamber is further provided in the shell, one end of the transition chamber is connected to the stirring chamber, and the other end is connected to the boosting chamber. Thus, when the raw material enters the boosting chamber from the stirring chamber, it can be compressed, and its pressure is increased, thereby reducing the pores inside the raw material, and further increasing its pressure when spraying, so as to further reduce the pores contained in the finished product.

[0008] In some embodiments, the stirring end is provided with multiple rows of protrusions, which are arranged at equal intervals around the center line of the stirring end. Thus, when the rotating shaft rotates, the protrusions can effectively contact the raw materials in the stirring chamber to fully stir the raw materials.

[0009] In some embodiments, a spiral groove is provided on the surface of the pressurizing end, so that when the rotating shaft rotates, the spiral groove can also rotate accordingly to effectively increase the pressure of the raw material in the pressurizing chamber.

[0010] In some embodiments, the spray block includes a spray block body and a protrusion, wherein the protrusion is multiple, all of which are connected to the side of the spray block body, and a spray cavity is enclosed between two adjacent protrusions, the side wall of the discharge cavity and the spray block body. Thus, the raw material entering the discharge cavity can only be sprayed out from the spray cavity located on the side of the spray block body under the obstruction of the spray block body and the protrusion, so as to ensure the realization of multi-directional spraying.

[0011] In some embodiments, the projection of the protrusion on the horizontal plane is in the shape of an arc. The protrusion is set in the above shape to make the spraying cavity fan-shaped, so that when the rotating shaft rotates, the raw material in the spraying cavity can be sprayed by a certain centrifugal force, so as to ensure that the raw material can be effectively sprayed onto the side wall of the mold and ensure that the raw material can be fully dispersed to reduce the air holes in the finished product.

[0012] In some embodiments, the spray block body is truncated cone-shaped, and the shape of the discharge cavity matches the shape of the spray block body. The truncated cone-shaped structure enables gravity to provide a certain centrifugal force to ensure that the raw materials can be sprayed out better.

[0013] In some embodiments, the spray block body is provided with an upper groove, a lower groove and a through hole, the upper groove is provided at the top of the spray block body, the lower groove is provided at the bottom of the spray block body, and the upper groove and the lower groove are connected through the through hole.

[0014] In some embodiments, the present invention further comprises a nut, the rotating shaft is provided with an extension end and a threaded end, the extension end and the threaded end are connected, the upper groove is sleeved on the extension end, the threaded end passes through the through hole and is threadedly connected to the nut. Thus, the spray block can be clamped by the nut and the extension end, the connection between the spray block and the rotating shaft is realized, and the reliability of the connection between them is ensured.

[0028] The spray block 3 includes a spray block body 31 and protrusions 32. The spray block body 31 is truncated cone-shaped, and there are twelve protrusions 32. The projection of the protrusions 32 on the horizontal plane is arc-shaped. All protrusions 32 are integrally connected to the side of the spray block body 31, and the protrusions 32 are evenly distributed on the spray block body 31. The discharge chamber 13 is arranged at the periphery of the spray block 3, and the shape of the discharge chamber 13 matches the shape of the spray block body 31, so that the side wall of the discharge chamber 13 is in contact with each protrusion 32, so that a spray chamber 10 can be enclosed between two adjacent protrusions 32, the side wall of the discharge chamber 13 and the spray block body 31, that is, the present invention contains twelve spray chambers 10, and all the spray chambers 10 are connected to the boost chamber 12.

[0029] An upper groove 311, a lower groove 312 and a through hole 313 are also provided on the spray block body 31 of the spray block 3. The upper groove 311 is provided at the top of the spray block body 31, and the lower groove 312 is provided at the bottom of the spray block body 31.
