Description

Technical Field

[0001] This invention belongs to the field of die casting machine technology, specifically relating to a hook-type alloy balance block die casting machine. Background Technology

[0002] Die casting machines, as crucial equipment for manufacturing metal alloy castings, are widely used in the automotive, aerospace, and machinery manufacturing industries. With the increasing demands for industrial automation and high-precision manufacturing, die casting machines face higher requirements in terms of structural design and functional performance. Traditional die casting machines have many shortcomings in mold changing, molding efficiency, and the molding of complex structural parts, especially in achieving rapid mold changes and molding complex hook structures.

[0003] Existing die-casting machines mostly adopt traditional mold-closing and injection structures. The mold-closing and locking systems lack sufficient rigidity, which makes the mold prone to warping, flash, and other defects during high-pressure injection, affecting product quality.

Detailed Implementation

[0027] like Figures 1 to 8 As shown, a hook-type alloy balance block die-casting machine includes a frame body 10. A mold-closing mechanism 20 and an injection cylinder 30 are respectively installed on the upper part of the frame body 10. One end of the injection cylinder 30 is equipped with an injection nozzle 31, which is correspondingly positioned with the mold-closing mechanism 20. In use, after the mold-closing mechanism 20 closes and locks the mold, the injection cylinder 30, driven by the control system, pushes the injection piston, causing molten alloy liquid to be injected at high speed into the mold cavity through the injection nozzle 31, completing the die-casting filling. The mold cavity is provided with a cavity shape matching the hook-type structure and is equipped with a core-pulling mechanism for forming the hook structure.

[0028] In practical implementation, the mold closing mechanism 20 is connected to several guide pillars and tie rods 21 at its edge to guide the linear movement of the template during mold closing and opening, ensuring coaxiality and accuracy when the mold is closed. A mold closing cylinder 22 is installed at the rear of the mold closing mechanism 20, providing sufficient closing force via hydraulic drive to ensure stable mold closure during high-pressure injection and prevent flash, misalignment, and other phenomena. A lower hook cylinder 23 is installed at the upper front end of the mold closing mechanism 20 to control the movement of movable parts related to the hook structure, particularly suitable for achieving precise control and smooth demolding of the hook portion within the mold. Core-pulling cylinders 24 are symmetrically installed on both sides of the front of the mold closing mechanism 20. These core-pulling cylinders 24, in conjunction with a core-pulling structure installed on the movable template, realize the parting action of the rear wall of the hook balance block, suitable for product molding requirements with complex structures such as rear parting, reverse snaps, or grooves. In operation, after the operator or automatic control system initiates the die-casting cycle, the mold closing cylinder 22 first moves the moving mold plate along the guide rod 21 to close with the fixed mold plate. Simultaneously, the lower hook cylinder 23 and the core-pulling cylinder 24 are pre-reset and lock the relevant components. Subsequently, the injection cylinder 30 is activated, injecting the molten alloy into the mold cavity through the nozzle 31 to complete the filling. After the product cools and solidifies, the core-pulling cylinder 24 first actuates to pull out the core, the lower hook cylinder releases the hook structure, and finally the mold closing cylinder retracts to open the mold. The ejector system then ejects the finished product, completing the entire die-casting cycle.

[0029] In practical implementation, the upper two sides of the frame body 10 are symmetrically equipped with latching cylinders 11. These two latching cylinders 11 are connected to the front two sides of the mold closing mechanism 20 via pipes. The latching cylinders 11 drive the latching structure installed at the front end of the mold closing mechanism 20 to perform closing and releasing actions. During use, after the mold has closed and the core-pulling cylinder and lower hook cylinder have reset, the system controls the latching cylinder 11 to precisely close the latching mechanism at the mold inlet or the product hook forming area, thereby restricting and guiding the molten metal at a specific location, ensuring the integrity of the product's appearance and the full forming of the hook structure. The latching cylinder 11 provides additional locking force during the mold closing and pressurization process to prevent metal splashing or gate overflow.

[0030] In practical implementation, a mold-closing pressure booster valve 221 and a mold-closing valve 222 are respectively installed on one end of the rear side of the frame body 10. The mold-closing pressure booster valve 221 and the mold-closing valve 222 are connected to the mold-closing cylinder 22 through pipelines, and are used to implement conventional drive control and enhanced mold-locking control for the mold-closing cylinder 22. In use, when the system receives an automatic production command, the mold-closing valve 222 is activated first, and the piston of the mold-closing cylinder 22 is pushed forward by hydraulic drive, so that the moving platen moves along the guide post towards the fixed platen, completing the initial closing of the mold. After the mold is closed and in contact, in order to prevent the mold from bulging, flash and other quality defects caused by the impact of high-pressure metal during injection, the system then controls the mold-closing pressure booster valve 221 to open, inject higher pressure hydraulic oil into the mold-closing cylinder 22, and perform a high-intensity mold-locking pressure boosting operation on the mold to ensure that the mold remains reliably closed during injection molding.

[0031] In practical implementation, a core-pulling valve 241 and a hook valve 231 are respectively installed on the middle of the rear side of the frame body 10. The core-pulling valve 241 is connected to the core-pulling cylinder 24 through a pipe, and the hook valve 231 is connected to the hook cylinder 23 through a pipe, used to control the action sequence and execution logic of the core-pulling cylinder 24 and the hook cylinder 23 respectively. In use, after the mold completes mold closing and pressurization, the control system first activates the hook valve 231 according to the set program flow, causing the hook cylinder 23 to move and press and position the hook structure inside the mold, providing a stable mold cavity structure for subsequent injection molding. After the hook action is completed, the system then controls the core-pulling valve 241 to move, causing the core-pulling cylinder 24 to push the core-pulling mechanism to insert or withdraw from the cavity, forming complex undercut or hollow parts of the product, which is particularly suitable for die-casting parts that require special structures, such as hook-type alloy balance blocks.

[0032] In practical implementation, an injection valve 32 and a nozzle valve 111 are respectively installed on the other end of the rear side of the frame body 10. The injection valve 32 is connected to the injection cylinder 30 through a pipe, and the nozzle valve 111 is connected to the nozzle cylinder 11 through a pipe. During use, the system controller first activates the nozzle valve 111 according to the automated program flow, driving the nozzle cylinder 11 to close the nozzle mechanism, sealing the gate or auxiliary structure area at the front of the mold, ensuring a clear metal flow path and good sealing in the subsequent injection process, and preventing quality problems such as flying material and leakage. Subsequently, the controller activates the injection valve 32, controlling the injection cylinder 30 to advance rapidly, injecting molten alloy at high speed into the well-closed mold cavity through the nozzle, completing the product filling. During the holding pressure stage, the injection cylinder maintains pressure to ensure product density. After the holding pressure is completed, the injection cylinder returns, and the nozzle cylinder resets under system command, opening the nozzle structure, preparing for the next step of mold opening, core pulling, and product ejection.

[0033] In practical implementation, an oil pump motor 40 is installed on the side of the frame body 10 to provide a stable power source for the entire hydraulic system; a cooler 50 is installed at the lower rear of the frame body 10 to cool the working oil in the hydraulic system, preventing high temperatures from affecting system stability and component lifespan. A pressure regulating valve 12 is installed at the lower end of the mold closing valve 222 to adjust the working pressure of the hydraulic system to adapt to the process requirements of different die-casting molds and products; the pressure regulating valve 12 is connected to the oil pump motor 40 and the cooler 50 through pipelines, forming a complete, closed, and controllable oil circuit circulation system for the entire hydraulic control system. One end of the cooler 50 is connected to a cooling water inlet 51 and a cooling water outlet 52, forming an independent cooling water circulation loop for efficient oil temperature control. When in use, the oil pump motor 40 starts, and the hydraulic oil is pumped into the oil circuit of each actuator at the required pressure through the pressure regulating valve 12. The cooler 50 cools down the high-temperature oil to ensure temperature rise control during long-term operation of the system.

[0034] In practical implementation, a quick-acting valve 33 is installed at the lower end of the injection valve 32. This quick-acting valve 33 is electromagnetically controlled for mold closing, mold opening, and core insertion, enabling rapid action when needed and saving idle time. An injection pressure gauge 34 is installed on one side of the quick-acting valve 33 to monitor pressure changes during the injection process in real time, ensuring the stability of the injection process and the quality of the product molding. A pressure relief switch 35 is installed on the other side of the quick-acting valve 33, which is used to depressurize the pressure-holding section of the injection oil circuit before maintenance. A system pressure gauge 13 is installed at the upper end of the mold closing pressure boosting valve 221 to monitor the working pressure status of the entire hydraulic system in real time. This serves as one of the feedback signal sources for system operation status detection and automatic adjustment, contributing to precise mold closing and safe control. When in use, the pressure relief switch 35 is part of the injection hydraulic system. When maintenance is required, the pressure needs to be released first. The quick valve 33 mainly provides flow to achieve rapid operation when the mold is closed. The injection pressure gauge 34 provides real-time data to judge the filling quality. The monitoring of the system pressure gauge 13 provides a basis for ensuring the safe operation of the whole machine, fault warning, and pressure regulation.

[0035] In practical implementation, an energy storage device 14 is installed on the rear side of the frame body 10. The main function of the energy storage device 14 is to store hydraulic energy for pressure injection to achieve continuous and stable injection of materials over a large range. The limit switches of each part are signals for each action in the automatic cycle operation, providing closed-loop signals for PLC control.

[0036] In practical implementation, a vibratory feeder 60 is installed on the upper end of the frame body 10. This vibratory feeder is used to arrange and directionally feed the metal parts or components required for the hook-type alloy balance block, thereby improving feeding efficiency and automation level. A vibratory feeder vibration adjustment unit 61 is installed on the front side of the frame body 10. This unit adjusts the vibration intensity and frequency according to the workpiece type, size, and feeding rhythm to achieve precise feeding control. A vibratory feeder switch 62 is located on one side of the vibration adjustment unit 61, facilitating start and stop control of the vibratory feeder by the operator.

[0037] In practical implementation, the mold closing cylinder 22 is equipped with an opening stop 223, a closing pressure booster 224, and a closing stop 225 on one side. These three components are arranged sequentially. The opening stop 223 is used to terminate the mold movement during the mold opening stage. The closing pressure booster 224 provides secondary high-pressure locking during the mold closing process to ensure tight mold closure and improve the density and dimensional accuracy of the die-cast alloy material. The closing stop 225 is used at the end of the mold closing stroke to ensure consistent mold closing position each time, improving product consistency and repeatability. A mold closing pressure gauge 226 is provided on the other side of the mold closing cylinder 22 to monitor and provide feedback on the actual mold closing pressure gauge value.

[0038] In practical implementation, the lower hook cylinder 23 is provided with an upper hook stop 232, a lower hook stop 233, and a no-hook detection 234 on one side. The upper hook stop 232, the lower hook stop 233, and the no-hook detection 234 are arranged in sequence. The upper hook stop 232 is used to detect the position of the lower hook cylinder 23 in the hook-retracting state to ensure that the hook is in the ready state. The lower hook stop 233 is used to detect its position in the hook-down (hook delivery) state to ensure the positional accuracy when the hooking action is completed. The no-hook detection 234 is used to identify abnormalities when the hook is not properly installed or not in place, so as to issue an alarm signal or automatically stop the die-casting cycle.

[0039] In practical implementation, the core-pulling cylinder 24 is provided with a core-pulling stop 242 and a core-insertion stop 243 on one side, which are arranged sequentially along the axial movement direction of the core-pulling cylinder 24. The core-pulling stop 242 is used to detect the position of the core-pulling cylinder 24 when the core rod is completely withdrawn from the mold cavity, preventing over-travel from causing mechanical interference or mold damage; the core-insertion stop 243 is used to detect the end position of the core rod when it is inserted into the mold cavity, ensuring that the core rod is inserted in the same position each time, thus ensuring the accuracy of the product molding structure.

[0040] In practical implementation, a stop 112 is provided on one side of the nozzle cylinder 11 to limit the termination position of the piston of the nozzle cylinder 11 during operation. The stop 112 is set at the moving end of the nozzle cylinder by a position sensor to precisely control the closing degree of the nozzle mechanism, ensure a tight seal between the nozzle and the mold, and prevent the alloy liquid from leaking or splashing during injection.

[0041] In practical implementation, the side of the injection cylinder 30 is provided with a return stop 36, which is used to detect the termination position of the injection cylinder 30 during the return process. The return stop is set at the end point of the return of the injection cylinder 30 through a stroke position sensing device to ensure that the injection piston can stably return to the initial standby position after completing one injection cycle, so as to avoid position deviation affecting the accuracy and synchronization of the next injection action.

[0042] In practical implementation, an oil level gauge 15 and a discharge gate 16 are respectively installed on the front side of the frame body 10. The oil level gauge 15 is used to monitor the oil level in the hydraulic system of the die-casting machine in real time, so that the operator can grasp the oil status and replenish or maintain it in a timely manner. The discharge gate 16 receives a signal from the detection switch to check whether the product has passed through smoothly. This signal is the automatic (single cycle) end signal and also the signal to start the next cycle.

[0043] In practical implementation, the mold closing mechanism 20 includes a front template 25, a front mold base 251, a front mold core 26, a moving mold core 27, a moving template 28, and a moving mold base 281. These components are sequentially connected. During operation, the die-casting machine drives the moving template 28 to move along the mold closing direction, thereby moving the moving mold base 281 and the moving mold core 27. When the moving mold core 27 and the front mold core 26 are closed, a complete mold cavity structure is formed. After the die-casting process is completed, the moving template 28 drives the moving mold core 27 to open, achieving the demolding action. This structural design achieves efficient and stable mold opening and closing, making it suitable for automated injection molding production processes.

[0044] In practical implementation, the machine's workflow is as follows: Start-up (button or electrical start), spraying (spraying the mold demolding section), core insertion (sealing the two front mold cores 26), hooking (hook cylinder 23 delivers the hook to the hook groove of the front mold core 26), mold closing (the moving mold core 27 and the front mold core 26 close), mold closing pressure increase, nozzle locking (the action of nozzle cylinder 11 locks the nozzle 31 and the nozzle hole of the front mold core 26), injection (injection), cooling (time expires), mold opening (the moving mold core 27 disengages), core pulling (the front mold core 26 separates), the hook cylinder pushes the product down to fall off, the product is ejected (feeding gate detection), and the cycle is completed.

[0045] In summary, the upper part of the frame body 10 is equipped with a mold clamping mechanism 20 and an injection cylinder 30. One end of the injection cylinder 30 is provided with an injection nozzle 31, which is correspondingly arranged with the mold clamping mechanism 20. The edge of the mold clamping mechanism 20 is connected with several guide pillars and tie rods 21. The rear part of the mold clamping mechanism 20 is equipped with a mold clamping cylinder 22. The upper front end of the mold clamping mechanism 20 is equipped with a hook cylinder 23.

The upper two sides of the frame body 10 are symmetrically equipped with latching cylinders 11, which are connected to the front two sides of the mold clamping mechanism 20 through pipes. The hook-type alloy balance block die casting machine of the present invention can realize rapid mold change, high degree of automation, significantly improve production efficiency and mold change efficiency, and at the same time ensure the yield of finished products.
