Description

Technical Field

[0001] The invention relates to the technical field of screw rod die-casting dies, and in particular to a screw rod housing die-casting die and a use method thereof. Background Art

[0002] The screw housing die casting mold is a mold used to produce screw housing (or screw housing) parts. Screw housings are usually used in mechanical or electrical equipment to support or protect them. Die casting is a common metal casting process that injects molten metal (usually aluminum, zinc or magnesium alloy) into a mold under high pressure to form parts with complex shapes; In the prior art, during die casting, the required material is melted and squeezed into the mold, and then the mold is solidified to form a desired product. However, during use, cavities are likely to appear, resulting in uneven die casting. At the same time, the cooling speed is slow, which is not conducive to saving molding time. In order to overcome the above shortcomings, the Chinese patent of the prior art (publication number CN112517882B) discloses a die-casting mold for a steering gear housing, wherein a molding cavity is formed between a fixed mold core and a movable mold core, a material pipe is embedded in the fixed mold plate, a diverter cone is provided on the side where the movable mold plate is close to the movable mold plate, a first diverter channel and a second diverter channel are provided on the side where the fixed mold core and the movable mold core are in contact, and the first gate and the second gate are also provided, and a straight-tube molding mechanism and a molding cavity exhaust mechanism are also provided. The flow path of the aluminum liquid in the molding cavity of the die-casting mold is optimized, which can ensure that the aluminum liquid is more completely injected into the entire molding cavity, and the solidification degree of the aluminum liquid in the molding cavity is more consistent, and it is less likely that the aluminum material of the molded product will be uneven and pores will appear, thereby improving the qualified rate and overall quality of the molded product; In order to overcome the above shortcomings, the Chinese patent of the prior art (publication number CN115519091A) discloses a die-casting mold cooling device, which rotates the screw to make the block slide and drive the shell to move. The movement of the shell makes the pasting plate and the male mold plate move and cooperate with the female mold plate to form a die-casting molding cavity. The conveying gun conveys the liquid raw material through the flow groove die-casting into the die-casting molding cavity. The cooling water flowing inside the condenser cools and molds the extruded product. After the product is formed, the male mold plate and the female mold plate are separated and the telescopic cylinder moves to extend to drive the die-casting product to be demolded from the outside of the male mold plate. The temperature of the die-casting molding cavity cooled by the condenser increases, and the circulation heating is conducted through the one-way valve through the copper rod to deform the inner side of the heat memory metal strip until the contact is triggered to achieve the cooling water temperature rising to a fixed constant temperature and then discharged through the electric pump; Although the existing technology can overcome the above-mentioned deficiencies, there are still other problems in its operation. For example, when die casting is performed, the overall temperature of the device gradually rises, and the cooling mechanism used is limited to cooling the mold. The cooling effect on the external shell of the device is poor, which can easily cause the entire device to be in a high temperature state. The contact between cold and hot can easily cause damage to the connection position, which is not conducive to the continuous operation of the device. Summary of the invention

[0003] The object of the present invention is to provide a screw housing die-casting mold and a method of using the same, so as to solve the problem proposed in the above background technology that during die-casting, the overall temperature of the device gradually rises, and the cooling mechanism used is limited to cooling the mold, and the cooling effect on the external shell of the device is poor, which easily leads to the overall high temperature state of the device.

The comprehensive cooling mechanism is provided with a water inlet pipe, and the water inlet pipe runs through the storage box. A one-way valve is arranged inside the water inlet pipe.

[0005] Furthermore, a hydraulic telescopic rod is installed through the outer side of the fixed block, and the output end of the hydraulic telescopic rod corresponds to the position of the contact rod, and a slider is arranged on the inner side of the contact rod, and the slider is arranged corresponding to the inner position of the mold core.

[0006] Furthermore, a liquid inlet is provided at the upper end of the mold core, and a groove opening is provided at the upper end of the shell, and the groove opening corresponds to the position of the liquid inlet, and a flow groove is provided on the surface of the mold core.

[0007] Furthermore, the center of the circulation groove is connected to the molded product, and the outer side of the circulation groove is arranged corresponding to the liquid inlet, and the outer side of the molded product is fitted with the slider, and a limiting plate is provided at the upper end of the mold core, and mold cooling ports are provided at the rear of the lower mold and the upper mold, and the output end of the mold cooling port is aligned with the mold frame.

[0008] Furthermore, a first bevel gear is fixedly mounted on the output end of the driving motor, a second bevel gear is meshedly mounted on the upper end of the first bevel gear, a threaded rod is disposed at the middle end of the second bevel gear, and a rear end of the threaded rod is a reciprocating thread.

[0009] Furthermore, the threaded rod is rotatably mounted on the front end of the shell through a fixing sleeve, and an extrusion block is threadedly mounted on the rear end of the threaded rod, and a limiting groove is provided at the lower end of the extrusion block, the limiting block is fixedly mounted on the surface of the shell, and the connection between the limiting block and the limiting groove is a sliding connection.

[0010] Furthermore, limiting rods are fixedly installed on both sides of the front end of the positioning plate, and a movable plate is installed through the front end of the limiting rod, and a vibration spring is fixedly installed between the movable plate and the positioning plate, and the vibration spring is nested in the surface of the limiting rod, and a knocking block is fixedly installed at the rear end of the movable plate, and the knocking block corresponds to the position of the lower mold, and the knocking block passes through the hole in the center of the positioning plate, and the movable plate corresponds to the position driven by the extrusion block.

[0011] Furthermore, a rotating rod is rotatably installed at the front end of the shell through a fixed sleeve, and the rotating rod rotates synchronously with the threaded rod through a belt, and an adjusting rod is fixedly installed at the rear end of the rotating rod, and a round rod is fixedly installed on the outer side of the rear end of the adjusting rod, and a movable push plate is nested on the surface of the round rod.

[0012] Furthermore, the movable push plate is in a "T" shape, and a piston plate is fixedly installed on the outer side of the movable push plate, and the outer side of the piston plate is attached to the inner wall of the storage box through a sealing strip, and a cooling pipe is installed through the outer side of the storage box, and the output end of the cooling pipe is aligned with the surface of the device.

[0013] Furthermore, the method specifically includes the following steps: S1: Before using the device, the upper mold is aligned with the lower mold by starting the shell to move and compress the mold frame. During die-casting, the liquid material for die-casting of the screw housing is injected through the groove opening, and the liquid material entering from the groove opening enters the flow slot from the liquid inlet. At the same time, the hydraulic telescopic rod on the outside of the fixed block is started, and the hydraulic telescopic rod is aligned with the contact rod for punching. The contact rod is squeezed and pushes the slider to move inward to extrude the material inside the die core, so that the material can be filled in the groove of the molded product. After the limiting plate seals the die core, the module and the die core are cooled through the mold cooling port, so that the screw housing can be quickly cooled and formed to ensure the working efficiency of the device; S2: When in use, by starting the driving motor, the output end of the driving motor drives the second bevel gear to rotate through the first bevel gear, and the second bevel gear drives the threaded rod to rotate. When the threaded rod rotates, the extrusion block threadedly connected at its rear end moves forward and backward along the direction of the thread. A limiting groove is provided at the bottom of the extrusion block. Under the limit of the limiting block, it can be restricted and can only move forward and backward. Therefore, the extrusion block squeezes the moving plate. After the moving plate is squeezed, it moves backward along the direction of the limiting rod to squeeze the vibration spring until the knocking block on the inner side of the moving plate passes through the positioning plate and contacts the lower mold, thereby realizing the knocking function. At the same time, when the extrusion block moves in the opposite direction to the front end to release the squeezing of the moving plate, the moving plate vibrates back and forth along the limiting rod under the elastic force of the vibration spring itself, which can achieve the effect of improving the knocking vibration, ensure the efficiency of knocking, and make the mold vibrate, so as to avoid the problem of uneven die-casting caused by the existence of gaps when the liquid material solidifies inside the mold core, thereby improving the die-casting effect of the device. S3: When the threaded rod rotates, the limited rotating rod is driven to rotate by the belt. When the rotating rod rotates, it drives the adjusting rod at the rear end. The rotation of the adjusting rod drives the round rod to move back and forth in the groove on the right side of the movable push plate, and at the same time, it can push the movable push plate to move back and forth in the storage box. The reciprocating movement of the movable push plate enables the piston plate to move back and forth along the inside of the storage box under the action of the sealing strip. At the same time, water is added to the storage box through the water inlet pipe, and a one-way valve is arranged inside the water inlet pipe. When the piston plate moves back and forth to squeeze the water inside the storage box, the water can be prevented from flowing back. The squeezed water can be sprayed along the cooling pipe to cool down the entire device, so as to avoid inconsistent temperature of the entire device, increase the service life of the device, and prevent the device from being easily damaged.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Before using the device, the upper mold is aligned with the lower mold by starting the shell to move and compress the mold frame. During die casting, the liquid material for die casting of the screw shell is injected through the groove opening, and the contact rod is squeezed to push the slider to move inward to extrude the material inside the die core, so that the material can be filled in the groove of the molded product, improving the filling effect of the material and the die casting effect; Furthermore, after the limiting plate seals the mold core, the module and the mold core are cooled through the mold cooling port, so that the screw housing can be quickly cooled and formed to ensure the working efficiency of the device; 2. When in use, by starting the driving motor, the output end of the driving motor drives the second bevel gear to rotate through the first bevel gear, and the second bevel gear drives the threaded rod to rotate until the knocking block on the inner side of the moving plate passes through the positioning plate to contact the lower mold, thereby realizing the knocking function, avoiding the problem of uneven die-casting caused by gaps when the liquid material solidifies inside the mold core, improving the die-casting effect of the device, and enabling the mold to vibrate, avoiding the problem of uneven die-casting caused by gaps when the liquid material solidifies inside the mold core, thereby improving the die-casting effect of the device; Furthermore, when the extrusion block moves in the opposite direction to the front end to release the extrusion on the movable plate, the movable plate vibrates back and forth along the limit rod under the elastic force of the vibration spring itself, which can improve the effect of knocking vibration, ensure the efficiency of knocking, and enable the mold to vibrate efficiently; 3. When the threaded rod rotates, the belt drives the limited rotating rod to rotate. When the rotating rod rotates, it drives the adjusting rod at the rear end. The rotation of the adjusting rod drives the round rod to move back and forth in the groove on the right side of the moving push plate. The squeezed water is sprayed along the cooling pipe to cool the entire device, avoiding inconsistent overall temperature of the device, increasing the service life of the device, and preventing the device from being easily damaged.

When the threaded rod 19 rotates, the extrusion block 20 threadedly connected to its rear end moves forward and backward along the direction of the thread.

The screw housing die casting mold according to claim 1, characterized in that: A rotating rod (29) is rotatably mounted on the front end of the housing (1) via a fixing sleeve, and the rotating rod (29) rotates synchronously with the threaded rod (19) via a belt (28), and an adjusting rod (30) is fixedly mounted on the rear end of the rotating rod (29), and a round rod (31) is fixedly mounted on the outer side of the rear end of the adjusting rod (30), and a movable push plate (32) is nested on the surface of the round rod (31).

9. The screw housing die casting mold according to claim 8, characterized in that: The movable push plate (32) is in a T-shape, and a piston plate (33) is fixedly mounted on the outer side of the movable push plate (32), and the outer side of the piston plate (33) is attached to the inner wall of the storage box (34) via a sealing strip, and a cooling pipe (35) is installed through the outer side of the storage box (34), and the output end of the cooling pipe (35) is aligned with the surface of the device.

10. A method for using a screw housing die-casting mold, characterized in that: The specific steps include: S1: Before using the device, the housing (1) is started, and the upper mold (3) is aligned with the lower mold (2) to move and compress the mold frame (4). During die casting, the liquid material for die casting of the screw housing (1) is injected through the groove opening (10). The liquid material entering from the groove opening (10) enters the flow groove (12) from the liquid inlet (11). At the same time, the hydraulic telescopic rod (7) outside the fixed block (6) is started, and the hydraulic telescopic rod (7) is aligned with the contact rod (8) for punching. The contact rod (8) is squeezed to push the slider (9) to move inward to squeeze the material inside the die core (5), so that the material can be filled in the groove of the molded product (13). After the limiting plate (14) seals the die core (5), the module and the die core (5) are cooled through the mold cooling port (15), so that the screw housing (1) can be quickly cooled and molded, thereby ensuring the working efficiency of the device; S2: When in use, by starting the driving motor (16), the output end of the driving motor (16) drives the second bevel gear (18) to rotate through the first bevel gear (17), and the second bevel gear (18) drives the threaded rod (19) to rotate. When the threaded rod (19) rotates, the extrusion block (20) connected to the rear end of the thread moves forward and backward along the direction of the thread. The bottom of the extrusion block (20) is provided with a limiting groove (21). Under the limit of the limiting block (22), the extrusion block (20) can be limited to move forward and backward. Therefore, the extrusion block (20) squeezes the moving plate (25). After the moving plate (25) is squeezed, it moves along the limiting rod (24). ) moves backward in the direction of the front end to squeeze the vibration spring (26) until the knocking block (27) on the inner side of the movable plate (25) passes through the positioning plate (23) and contacts the lower mold (2), thereby realizing the knocking function. At the same time, when the extrusion block (20) moves in the opposite direction to the front end to release the extrusion on the movable plate (25), the movable plate (25) reciprocates along the limit rod (24) under the elastic force of the vibration spring (26), thereby improving the knocking vibration effect, ensuring the knocking efficiency, and making the mold vibrate, thereby avoiding the problem of uneven die casting caused by the gap when the liquid material solidifies inside the mold core (5), thereby improving the die casting effect of the device; S3: When the threaded rod (19) rotates, the belt (28) drives the limited rotating rod (29) to rotate. When the rotating rod (29) rotates, it drives the adjusting rod (30) at the rear end. The rotation of the adjusting rod (30) drives the round rod (31) to move back and forth in the groove on the right side of the movable push plate (32), and can also push the movable push plate (32) to move back and forth in the storage box (34). The reciprocating movement of the movable push plate (32) enables the piston plate (33) to move back and forth along the storage box (34) under the action of the sealing strip. At the same time, water is added to the storage box (34) through the water inlet pipe (36). A one-way valve is provided inside the water inlet pipe (36). When the piston plate (33) reciprocates to squeeze the water inside the storage box (34), the water source is prevented from flowing back. The squeezed water is sprayed along the cooling pipe (35) to cool the entire device, thereby preventing the temperature of the entire device from being inconsistent, thereby increasing the service life of the device and preventing the device from being easily damaged.
