Multi-layer casting machine die head

Abstract

The utility model discloses a multi-layer casting machine die head which comprises a die head body, a discharge port is arranged at the bottom of the die head body, and a main cavity and an auxiliary cavity are arranged in the die head body. Due to the arrangement of the cleaning mechanism, in the using process, when the discharging port of the die head body needs to be cleaned, only the servo motor needs to be started, and the servo motor drives the stud to rotate stably. Due to the fact that the threaded moving plate is in threaded connection with the stud and is limited by the guide groove, when the stud rotates, the threaded moving plate can do precise linear movement in the guide groove in the axial direction of the stud, and then the mounting plate and the scraper are driven to move synchronously. In the moving process of the scraping plate, the inner wall and an outlet of the discharging port can be comprehensively cleaned, accumulated materials are cleaned, manual operation is not needed in the whole cleaning process, the cleaning time is greatly saved, the working efficiency is remarkably improved, and meanwhile the labor intensity of operators is greatly reduced.

Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically a multi-layer casting machine die head. Background Technology

[0002] Casting is a common material processing technology. Multi-layer casting machines are used to extrude multiple different materials at the same time and form products with multi-layer structures.

[0003] A search revealed a patent with application number CN202223152678.0, which discloses a casting machine die head for PE preservation film production, relating to the field of casting machine technology. It includes an upper die head with a main cavity and a secondary cavity extending through it. Connecting blocks are fixedly installed on the end walls of the upper die head. A main die head and a secondary die head are symmetrically arranged at the bottom of the upper die head, and both the main and secondary die heads are slidably connected to the connecting blocks. Guide blocks are fixedly installed between the connecting blocks. However, in long-term practical production applications, it has been found that this type of die head has significant defects: due to the lack of an effective cleaning function, when material becomes blocked at the outlet due to solidification, residue, or other reasons, it cannot be automatically cleaned and can only be manually cleaned by operators using tools. This manual cleaning method not only consumes a lot of time and seriously reduces production efficiency, but also greatly increases the labor intensity of operators; furthermore, during manual cleaning, improper operation may cause scratches and damage to the die head surface, thus affecting the die head's service life and product quality. Therefore, we propose a multi-layer casting machine die head. Summary of the Invention

[0004] The purpose of this invention is to provide a multilayer casting machine die head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer casting machine die head, comprising a die head body, a discharge port at the bottom of the die head body, a main cavity and a secondary cavity inside the die head body, a main flow channel communicating with the bottom of the main cavity, a secondary flow channel communicating with the bottom of the secondary cavity, the bottom of both the main flow channel and the secondary flow channel communicating with the discharge port, and a cleaning mechanism provided on the surface of the die head body.

[0006] Furthermore, the cleaning mechanism includes a fixed base, a guide groove, a servo motor, a stud, a threaded moving plate, a mounting plate, a scraper, bolts, a socket, and a threaded sleeve. A fixed base is fixedly connected to the upper left side of the mold head body, and a guide groove is provided at the bottom of the fixed base.

[0007] Furthermore, a servo motor is fixedly connected to the front side of the fixed base, and a stud is fixedly connected to the output end of the servo motor. The rear end of the stud passes through the fixed base and the guide groove in sequence and extends into the interior of the guide groove. The stud and the fixed base are movably connected.

[0008] Furthermore, the rear end of the stud is rotatably connected to the rear side of the inner wall of the guide groove via a bearing, and a threaded moving plate is threadedly connected to the front surface of the stud. The right side, top, and front side of the threaded moving plate are in contact with the inner wall of the guide groove. The above arrangement can limit and guide the threaded moving plate, so that the threaded moving plate cannot rotate with the stud.

[0009] Furthermore, the bottom of the threaded movable plate passes through the guide groove and extends to the outside of the guide groove and is fixedly connected to an installation plate, and a scraper is movably connected to the top right side of the installation plate.

[0010] Furthermore, the scraper is sized to match the discharge port, and two bolts are fixedly connected to the bottom of the scraper. An insertion hole is provided on the top of the mounting plate at the position corresponding to the bolts.

[0011] Furthermore, the bottom of the bolt penetrates the insertion hole and extends to the outside of the insertion hole, the bolt is movably inserted into the insertion hole, and a threaded sleeve is threaded onto the surface of the bolt, the top of the threaded sleeve abutting against the bottom of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the establishment of a cleaning mechanism, allows for easy cleaning of the die head's outlet during use. Simply activate the servo motor, which drives the stud to rotate stably. Because the threaded moving plate is threadedly connected to the stud and constrained by the guide groove, the threaded moving plate moves precisely in a straight line along the stud's axial direction within the guide groove as the stud rotates, thereby causing the mounting plate and scraper to move synchronously. During this movement, the scraper thoroughly cleans the inner wall and outlet of the discharge port, removing accumulated material. The entire cleaning process requires no manual operation, significantly saving cleaning time, greatly improving work efficiency, and drastically reducing the labor intensity of operators.

[0014] The scraper of this utility model is fixed to the mounting plate by bolts and threaded sleeves. When the scraper is severely worn, the scraper can be removed from the mounting plate and replaced simply by unscrewing the threaded sleeves, which is convenient, quick and reduces maintenance costs.

[0025] Please see Figure 1-7A multi-layer casting machine die head includes a die head body 1, a discharge port 2 at the bottom of the die head body 1, a main cavity 3 and a secondary cavity 4 inside the die head body 1, a main flow channel 5 communicating with the bottom of the main cavity 3, a secondary flow channel 6 communicating with the bottom of the secondary cavity 4, and the bottoms of both the main flow channel 5 and the secondary flow channel 6 communicating with the discharge port 2. A cleaning mechanism 7 is provided on the surface of the die head body 1.

[0026] Specifically, the cleaning mechanism 7 includes a fixed base 701, a guide groove 702, a servo motor 703, a stud 704, a threaded moving plate 705, a mounting plate 706, a scraper 707, a bolt 708, a socket 709, and a threaded sleeve 710. The fixed base 701 is fixedly connected to the upper left side of the mold head body 1, and the bottom of the fixed base 701 is provided with a guide groove 702.

[0027] In practical implementation, a servo motor 703 is fixedly connected to the front side of the fixed base 701, and a stud 704 is fixedly connected to the output end of the servo motor 703. The rear end of the stud 704 passes through the fixed base 701 and the guide groove 702 in sequence and extends into the guide groove 702. The stud 704 and the fixed base 701 are movably connected.

[0028] Specifically, the rear end of the stud 704 is rotatably connected to the rear side of the inner wall of the guide groove 702 via a bearing. The bearing effectively reduces the frictional resistance when the stud rotates, ensuring its stable rotation.

[0029] A threaded moving plate 705 is threadedly connected to the front of the stud 704. The right side, top and front side of the threaded moving plate 705 are in contact with the inner wall of the guide groove 702. The above arrangement can limit and guide the threaded moving plate 705, so that the threaded moving plate 705 cannot rotate with the stud 704.

[0030] In practice, the bottom of the threaded moving plate 705 passes through the guide groove 702 and extends to the outside of the guide groove 702 and is fixedly connected to the mounting plate 706. The top right side of the mounting plate 706 is movably connected to the scraper 707.

[0031] Specifically, the size of scraper 707 is matched with the discharge port 2, which can completely cover the discharge port and ensure the cleaning effect.

[0032] The bottom of the scraper 707 is fixedly connected to two bolts 708, and the top of the mounting plate 706 has a hole 709 corresponding to the position of the bolts 708.

[0033] In practice, the bottom of the bolt 708 passes through the socket 709 and extends to the outside of the socket 709. The bolt 708 and the socket 709 are movably connected. The bolt 708 is threaded with a threaded sleeve 710. The top of the threaded sleeve 710 abuts against the bottom of the mounting plate 706.

[0034] In practical applications: When using this multi-layer casting machine die head, the material flows through the main cavity 3 and the secondary cavity 4, and then through the main flow channel 5 and the secondary flow channel 6, exiting from the discharge port 2. When the discharge port 2 becomes blocked or needs cleaning, the servo motor 703 is activated. The servo motor 703 drives the stud 704 to rotate continuously in both directions. Under the limiting guidance of the guide groove 702, the threaded moving plate 705 moves back and forth along the stud 704, thereby driving the mounting plate 706 and the scraper 707 to move back and forth continuously. The scraper 707 then cleans the inner wall of the discharge port 2. When the scraper 707 is worn and needs to be replaced, the screw sleeve 710 is unscrewed to remove and replace the scraper 707.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
