Description

Technical Field

[0001] The present invention relates to the technical field of die-casting machines, and particularly relates to a non-ferrous metal high-pressure casting process and device. Background Art

[0002] Non-ferrous metal high-pressure casting is a manufacturing technology in which molten metal (such as aluminum alloy, magnesium alloy, copper alloy, etc.) is rapidly injected into a mold cavity under high pressure, and solidifies into a shape within a short time. This process usually occurs under high pressure, and the molten metal fills the mold at an extremely fast speed, and can solidify within a very short time to form parts with high density and good mechanical properties.

[0003] In the existing high-pressure casting process, when the molten metal is injected into the closed mold cavity under high pressure, the huge internal pressure is extremely likely to cause the mold gap to expand, especially the moving mold part, because its relative mobility is strong and it lacks sufficient rigid support, so it is very easy to be deformed by force and even slightly separated, seriously affecting the dimensional accuracy and surface quality of the casting. Moreover, the rapid expansion force of the molten metal in the cavity generates a strong adsorption force on the moving mold and the fixed mold during molding. When demolding, the pulling force of the casting is extremely powerful, especially for large and complex castings, this force is sufficient to cause slight but fatal deformation or offset of the fixed mold, destroying the original precise positioning of the mold. Based on this, the present invention purposefully provides a non-ferrous metal high-pressure casting process and device that can overcome the deformation and offset of the moving mold and the fixed mold during high-pressure casting. Summary of the Invention

[0004] The purpose of the present invention is to provide a non-ferrous metal high-pressure casting process and device for the deficiencies of the existing technology to solve the technical problems in the existing technology.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A non-ferrous metal high-pressure casting process includes the following steps:

[0007] Step S1: First, melt the non-ferrous metal raw material to obtain molten metal;

[0008] Step S2: Then, coat the inner cavities of the fixed mold and the moving mold with a release agent;

[0009] Step S3: Close the fixed mold and the moving mold, and lock the inverted trapezoidal block;

[0010] Step S4: The feeding component injects the molten metal into the cavity formed between the fixed mold and the moving mold under high pressure, and the molten metal rapidly solidifies under pressure to form the shape of the casting;

[0011] Step S5: Wait for the molten metal to cool and solidify in the mold cavity;

[0012] Step S6: Release the locked state of the inverted trapezoidal block through the reset component, and the reset component will press down the lower pressing plate against the extension block through the pressing-down component;

[0013] Step S7: Separate the fixed mold and the moving mold to take out the casting.

[0014] As a further solution of the present invention: The specific steps of step S3 are as follows:

[0015] Step S31: Drive the moving mold to descend through the driving source. At this time, the guide rod will gradually insert into the guide hole, and the inverted trapezoidal block will descend synchronously and abut against the insert block;

[0016] Step S32: As the moving mold continues to descend, the inverted trapezoidal block squeezes the insert block into the sliding groove and compresses the first spring;

[0017] Step S33: When the moving mold and the fixed mold are closed, at this time, the jack and the sliding groove are aligned, and the first spring pushes the insert block into the jack, thereby locking the inverted trapezoidal block. During the process of the insert block inserting into the jack, it is subjected to the force-relieving action of multiple rotating rods to prevent the insert block from generating too much impact in the jack.

[0018] As a further solution of the present invention: The specific steps of step S6 are as follows:

[0019] Step S61: The pre-tightening force of the second spring makes the moving plate abut against the regular trapezoidal block. Drive the regular trapezoidal block to rise through the output source, and the rising of the regular trapezoidal block will squeeze the moving plate to move;

[0020] Step S62: The movement of the moving plate will drive the insert block to move synchronously through the part of the insert block sliding in the groove, so that the insert block retracts from the jack into the sliding groove, releasing the locked state of the inverted trapezoidal block;

[0021] Step S63: The movement of the moving plate will make the inclined groove drive the round rod to move, and the movement of the round rod will drive the square slider to move downward in the square vertical groove, so that the lower pressing plate descends and abuts against the extension block.

[0022] A non-ferrous metal high-pressure casting process, characterized in that the non-ferrous metal high-pressure casting process is applied to a non-ferrous metal high-pressure casting device, and the device includes:

[0023] A casting table, on which a fixed mold is fixedly installed, and a moving mold is slidably installed thereon. The moving mold is located above the fixed mold, is communicated with a feeding component, and is driven by a driving source to move up and down. Two symmetrically arranged extension blocks are fixedly installed on the fixed mold. Two lower pressing plates are slidably installed on the casting table. The lower pressing plates are located above the extension blocks and are driven by a reset component to move up and down through a pressing-down component;

[0024] Inverted trapezoidal blocks. Two inverted trapezoidal blocks are fixedly installed on the moving mold, and the two inverted trapezoidal blocks are symmetrically arranged. The connection line of the two inverted trapezoidal blocks is perpendicular to the connection line of the two extension blocks. A jack is provided on the inverted trapezoidal block.

[0025] Fixed block, which is fixedly installed on the casting table, and a sliding groove is provided therein. An insertion block is slidably installed in the sliding groove. The insertion block is connected to the sliding groove through a first spring. When the inverted trapezoidal block descends, it abuts against and compresses the insertion block to move into the sliding groove until the inverted trapezoidal block descends to align the jack with the sliding groove, and the first spring pushes the sliding groove to insert into the jack.

[0026] Reset assembly, which is arranged on the casting table. Before the fixed mold and the moving mold are separated, the insertion block is driven to move out of the jack through the reset assembly. At the same time, the reset assembly drives the lower pressing plate to descend through the lower pressing assembly until the lower pressing plate abuts against the extension block. At this time, the driving source drives the moving mold to rise.

[0027] As a further scheme of the present invention: The reset assembly includes a fixed frame, a moving plate, a second spring, a regular trapezoidal block, a groove and a connecting block. The fixed frame is fixedly installed on the casting table. The moving plate is slidably installed on the fixed frame and is connected to the fixed frame through a second spring. The regular trapezoidal block is slidably installed on the casting table and is driven by an output source to rise and fall. The groove is provided on the moving plate. The connecting block is slidably installed in the groove and is fixedly connected to the end of the insertion block away from the jack. When the regular trapezoidal block rises, it squeezes the moving plate to move in a direction away from the axis of the regular trapezoidal block, and at this time the moving plate compresses the second spring.

[0028] As a further scheme of the present invention: The lower pressing assembly includes a square vertical groove, a square sliding block, an inclined groove and a round rod. The square vertical groove is provided on the fixed frame. The inclined groove is provided on the moving plate, which is inclined, and the horizontal height of the end away from the regular trapezoidal block is higher than the horizontal height of the end close to the regular trapezoidal block. The square sliding block is slidably installed in the square vertical groove. The round rod is slidably installed in the inclined groove, one end of which is fixedly connected to the square sliding block, and the other end is fixedly connected to the lower pressing plate.

[0029] As a further scheme of the present invention: A chamfer is provided on the insertion block. Three receiving grooves are provided at equal intervals on the top plate of the jack. A bearing plate is connected to each receiving groove through a third spring. A limiting groove is provided in the receiving groove. A convex plate is fixedly installed on the bearing plate, and the convex plate is slidably installed in the limiting groove. The bearing plate is slidably connected to the receiving groove, and a rotating rod is rotatably installed at the bottom end thereof, and the rotating rod abuts and cooperates with the chamfer.

[0030] As a further scheme of the present invention: A plurality of rollers are rotatably installed at one end of the moving plate close to the regular trapezoidal block and one end of the insertion block close to the inverted trapezoidal block.

[0031] The beneficial effects of the present invention:

[0032] 1. In the present invention, along with the process of the moving die and the fixed die being closed, the inverted trapezoidal block gradually cooperates with the insertion block to deepen. Eventually, the insertion block inserts into the insertion hole on the inverted trapezoidal block to complete the locking of the inverted trapezoidal block, thereby ensuring the rigid connection when the moving die and the fixed die are closed, and avoiding the deviation of the mold due to high pressure when injecting molten metal. Before demolding, the reset component drives the insertion block out of the insertion hole to unlock the inverted trapezoidal block. During the unlocking process, the reset component drives the lower pressing plate to descend and abut against the extension block through the lower pressing component, enabling the fixed die to overcome the strong adsorption force after the high-pressure casting is formed. When the moving die moves upward to perform demolding, the force that originally posed a threat to lift the fixed die is effectively dispersed, ensuring that the fixed die always remains stable in place and avoiding deformation and damage caused by the mutual traction between the molds;

[0033] 2. In the present invention, when the insertion block is pushed by the first spring and inserted into the insertion hole, the chamfer will hit the rotating rod, and then the rotating rod will gradually roll on the chamfer, thereby pushing the bearing plate to compress the third spring and finally retracting into the receiving groove. During the insertion process of the insertion block, it will be blocked by three rotating rods. In this way, the elastic force of the first spring can be dispersed and absorbed, avoiding the insertion block directly hitting the inside of the insertion hole to generate noise, and avoiding the vibration generated after the insertion block hits being transmitted back to the first spring in the reverse direction, protecting the insertion block and the first spring;

[0034] 3. In the present invention, through the setting of the rollers, when the inverted trapezoidal block descends, the insertion block will not directly abut against the inverted trapezoidal block, but the rollers will abut against the inverted trapezoidal block. As the inverted trapezoidal block descends, the rollers will roll on the inverted trapezoidal block. In this way, the sliding friction between the insertion block and the inverted trapezoidal block is changed into rolling friction, thereby reducing the resistance of movement. Similarly, the frictional resistance between the moving plate and the regular trapezoidal block can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0051] Please refer to Figures 1-13 As shown, the present invention is a non-ferrous metal high-pressure casting process, including the following steps:

[0052] Step S1: First, melt the non-ferrous metal raw material to obtain molten metal;

[0053] Step S2: Subsequently, release agents are applied to the inner cavities of the fixed mold 2 and the movable mold 3.

[0054] Step S3: The fixed mold 2 and the movable mold 3 are closed, and the inverted trapezoidal block 4 is locked.

[0055] Step S4: The feeding assembly hydraulically presses the molten metal into the cavity formed between the fixed mold 2 and the movable mold 3 under high pressure, and the molten metal quickly solidifies under pressure to form the shape of the casting.

[0056] Step S5: Wait for the molten metal to cool and solidify in the mold cavity.

[0057] Step S6: The locking state of the inverted trapezoidal block 4 is released by the reset assembly 8, and the reset assembly 8 will cause the lower pressing plate 10 to press down on the extension block 11 through the lower pressing assembly 9.

[0058] Step S7: The fixed mold 2 and the movable mold 3 are separated to take out the casting.

[0059] As Figures 1-13 shown, as a preferred embodiment of the present invention, the step S3 specifically includes the following steps:

[0060] Step S31: The movable mold 3 is driven to descend by the driving source. At this time, the guide rod 301 will gradually insert into the guide hole 201, and the inverted trapezoidal block 4 will descend synchronously and abut against the plug block 7.

[0061] Step S32: As the movable mold 3 continues to descend, the inverted trapezoidal block 4 squeezes the plug block 7 into the chute 601 and compresses the first spring 602.

[0062] Step S33: When the movable mold 3 is closed with the fixed mold 2, at this time, the jack hole 5 is aligned with the chute 601, and the first spring 602 pushes the plug block 7 to insert into the jack hole 5, thereby locking the inverted trapezoidal block 4, and the plug block 7 is subjected to the force unloading effect of a plurality of rotating rods 16 during the process of inserting into the jack hole 5 to prevent the plug block 7 from generating excessive impact in the jack hole 5.

[0063] As Figures 1-13 shown, as a preferred embodiment of the present invention, the step S6 specifically includes the following steps:

[0064] Step S61: The pre-tightening force of the second spring 803 causes the moving plate 802 to abut against the regular trapezoidal block 804. The regular trapezoidal block 804 is driven to rise by the output source, and the rising of the regular trapezoidal block 804 will squeeze the moving plate 802 to move.

[0065] Step S62: The movement of the moving plate 802 will drive the plug block 7 to move synchronously through the part of the plug block 7 that slides in the groove 805, so that the plug block 7 retracts from the jack hole 5 into the chute 601, releasing the locking state of the inverted trapezoidal block 4.

[0066] Step S63: The movement of the moving plate 802 causes the inclined groove 903 to drive the round rod 904 to move, and the movement of the round rod 904 drives the square slider 902 to move downward in the square vertical groove 901, so that the lower pressing plate 10 descends and abuts against the extension block 11.

[0067] Please refer to Figures 1-13 As shown in the figure, the present invention relates to a non-ferrous metal high-pressure casting process, which is characterized in that the non-ferrous metal high-pressure casting process is applied to a non-ferrous metal high-pressure casting device, and the device includes:

[0068] A casting table 1, on which a fixed mold 2 is fixedly installed, and a moving mold 3 is slidably installed thereon. The moving mold 3 is located above the fixed mold 2, is communicated with a feeding assembly, and is driven by a driving source to move up and down. Two symmetrically arranged extension blocks 11 are fixedly installed on the fixed mold 2. Two lower pressing plates 10 are slidably installed on the casting table 1. The lower pressing plates 10 are located above the extension blocks 11 and are driven by a reset assembly 8 to move up and down through a pressing-down assembly 9.

[0069] Inverted trapezoidal blocks 4, two inverted trapezoidal blocks 4 are fixedly installed on the moving mold 3, and the two inverted trapezoidal blocks 4 are symmetrically arranged. The connection line of the two inverted trapezoidal blocks 4 is perpendicular to the connection line of the two extension blocks 11. Insertion holes 5 are formed in the inverted trapezoidal blocks 4.

[0070] A fixed block 6, which is fixedly installed on the casting table 1 and has a sliding groove 601 formed therein. An insertion block 7 is slidably installed in the sliding groove 601. The insertion block 7 is connected to the sliding groove 601 through a first spring 602. When the inverted trapezoidal block 4 descends, it abuts against and compresses the insertion block 7 to move into the sliding groove 601 until the inverted trapezoidal block 4 descends to a position where the insertion hole 5 is aligned with the sliding groove 601, and the first spring 602 pushes the sliding groove 601 to insert into the insertion hole 5.

[0071] A reset assembly 8, which is arranged on the casting table 1. Before the fixed mold 2 and the moving mold 3 are separated, the reset assembly 8 drives the insertion block 7 to move out of the insertion hole 5, and at the same time, the reset assembly 8 drives the lower pressing plate 10 to descend through the pressing-down assembly 9 until the lower pressing plate 10 abuts against the extension block 11. At this time, the driving source drives the moving mold 3 to rise.

[0072] In one case of this embodiment, guide holes 201 are formed at the four corners of the fixed mold 2, and guide rods 301 are fixedly installed at the four corners of the moving mold 3. Each guide rod 301 is slidably matched with a guide hole 201. The driving source can be selected from components such as electric cylinders and hydraulic rods, and other mechanisms capable of realizing lifting motion can also be selected. This embodiment does not specifically limit this here. The feeding assembly can be selected from components such as die-casting machines and plunger injection units. This embodiment does not specifically limit this here.

[0073] Working principle of the present invention: First, non-ferrous metal raw materials (such as aluminum, copper, zinc, etc.) are melted to obtain molten metal, and then the molten metal is injected into the feeding assembly. Thus, the raw materials are prepared. Subsequently, a mold release agent is applied to the cavities of the fixed mold 2 and the moving mold 3, and then the moving mold 3 is driven by a driving source to descend for mold closing. During the mold closing process, the guide rod 301 slides in the guide hole 201 to play a guiding role;

[0074] During the mold closing process, as the moving mold 3 descends, as Figure 2 shown, the inverted trapezoidal block 4 will gradually descend and squeeze the insertion block 7 to move into the chute 601. Subsequently, as Figure 3 shown, when the moving mold 3 and the fixed mold 2 are closed, at this time, the insertion hole 5 is aligned with the chute 601, and the first spring 602 pushes the insertion block 7 into the insertion hole 5 to lock the inverted trapezoidal block 4. At this time, the feeding assembly injects the molten metal into the cavity formed between the fixed mold 2 and the moving mold 3 under high pressure. The molten metal quickly solidifies under pressure to form the shape of the casting. The locking of the inverted trapezoidal block 4 greatly enhances the rigidity of the moving mold 3, so that even in the face of extreme internal pressure, the fixed mold 2 and the moving mold 3 can still maintain a perfect fit, avoiding mold separation caused by the reaction force of the pressure;

[0075] Since the casting is formed under high pressure, it has a great adsorption force on the cavities of the fixed mold 2 and the moving mold 3. When the moving mold 3 rises, there will be a tendency to drive the fixed mold 2 to rise through the adsorption force of the formed casting on the fixed mold 2. Therefore, before mold opening, as Figure 4 shown, the reset assembly 8 drives the insertion block 7 out of the insertion hole 5 to unlock the inverted trapezoidal block 4. And during the unlocking process, the reset assembly 8 drives the lower pressing plate 10 to descend through the lower pressing assembly 9, so as to abut against the extension block 11. At this time, the moving mold 3 is driven by a driving source to rise for mold opening. The downward pressure of the lower pressing plate 10 on the extension block 11 enables the fixed mold 2 to overcome the strong adsorption force after the high-pressure casting is formed. When the moving mold 3 moves upward to perform mold opening, the force that would originally pose a threat to the lifting of the fixed mold 2 is effectively dispersed, ensuring that the fixed mold 2 always remains stable in place and avoiding deformation and damage caused by the mutual traction between the molds.

[0076] As Figures 5-6As shown, as a preferred embodiment of the present invention, the reset assembly 8 includes a fixed frame 801, a moving plate 802, a second spring 803, a regular trapezoidal block 804, a groove 805, and a connecting block 806. The fixed frame 801 is fixedly installed on the casting table 1. The moving plate 802 is slidably installed on the fixed frame 801 and is connected to the fixed frame 801 through the second spring 803. The regular trapezoidal block 804 is slidably installed on the casting table 1 and is driven by an output source to move up and down. The groove 805 is opened on the moving plate 802. The connecting block 806 is slidably installed in the groove 805 and is fixedly connected to the end of the insertion block 7 away from the insertion hole 5. When the regular trapezoidal block 804 rises, it squeezes the moving plate 802 to move away from the axis direction of the regular trapezoidal block 804, and at this time, the moving plate 802 compresses the second spring 803.

[0077] In a case of this embodiment, the output source can be selected from components such as electric cylinders and electric telescopic rods, and other mechanisms capable of realizing lifting motion can also be selected. This embodiment does not make specific limitations here.

[0078] When this embodiment is actually applied, as Figure 8 shown, due to the position limitation of the connecting block 806 in the groove 805, when the moving plate 802 moves towards the fixed frame 801, it will drive the connecting block 806 and the insertion block 7 to move synchronously, so that the insertion block 7 compresses the first spring 602 and retracts into the sliding groove 601. This process is the process in which the regular trapezoidal block 804 rises and squeezes the moving plate 802 to move, thereby driving the insertion block 7 out of the insertion hole 5, thus unlocking the inverted trapezoidal block 4. When the inverted trapezoidal block 4 rises, the regular trapezoidal block 804 descends to its original position. At this time, the second spring 803 and the first spring 602 will jointly push the moving plate 802 and the insertion block 7 back to their original positions, that is, from Figure 4 back to Figure 1 the state;

[0079] Due to the design of the groove 805, when the inverted trapezoidal block 4 descends and squeezes the insertion block 7 to move into the sliding groove 601, the connecting block 806 will slide in the groove 805, thus not affecting the independent movement of the insertion block 7, ensuring the smoothness of the locking and unlocking operations of the inverted trapezoidal block 4 and avoiding jamming.

[0080] As Figures 5-7As shown, as a preferred embodiment of the present invention, the pressing-down assembly 9 includes a square vertical groove 901, a square slider 902, an inclined groove 903, and a round rod 904. The square vertical groove 901 is formed on the fixed frame 801, and the inclined groove 903 is formed on the moving plate 802. The inclined groove 903 is arranged obliquely, and the horizontal height of the end away from the regular trapezoidal block 804 is higher than the horizontal height of the end close to the regular trapezoidal block 804. The square slider 902 is slidably installed in the square vertical groove 901, and the round rod 904 is slidably installed in the inclined groove 903. One end of the round rod 904 is fixedly connected to the square slider 902, and the other end is fixedly connected to the lower pressing plate 10.

[0081] In a case of this embodiment, as Figure 5 shown, at this time, the square slider 902 is located above the square vertical groove 901. Actually, the position of the inclined groove 903 at the round rod 904 is as Figure 8 shown. When the regular trapezoidal block 804 rises to squeeze the moving plate 802 to move, the movement of the moving plate 802 makes the insertion block 7 move into the sliding groove 601 on the one hand, so as to unlock the inverted trapezoidal block 4. On the other hand, the movement of the moving plate 802 makes the inclined groove 903 drive the round rod 904 to move. Due to the restriction of the moving direction of the square slider 902 by the square vertical groove 901, the square slider 902 descends. Therefore, the lower pressing plate 10 will descend to abut against the extension block 11. At this time, as Figure 6 shown. The square design of the square vertical groove 901 and the square slider 902 avoids the situation of the lower pressing plate 10 flipping, ensuring that the lower pressing plate 10 can fully abut on the extension block 11 and fully absorb and counteract the upward force on the extension block 11 during mold splitting. Such a design can link the operations of unlocking the inverted trapezoidal block 4 and pressing down the extension block 11, ensuring the realization of the effect while simplifying the operation.

[0082] As Figures 8-13 shown, as a preferred embodiment of the present invention, a chamfer 701 is provided on the insertion block 7. Three equally spaced receiving grooves 13 are formed on the top plate of the insertion hole 5. A bearing plate 14 is connected to each receiving groove 13 through a third spring 15. A limiting groove 1301 is formed in the receiving groove 13. A convex plate 1401 is fixedly installed on the bearing plate 14. The convex plate 1401 is slidably installed in the limiting groove 1301. The bearing plate 14 is slidably connected to the receiving groove 13, and a rotating rod 16 is rotatably installed at the bottom end of the bearing plate 14. The rotating rod 16 is in abutting cooperation with the chamfer 701.

[0083] In a case of this embodiment, the elastic force of the first spring 602 is greater than the elastic force of the third spring 15.

[0084] When this embodiment is actually applied, as Figure 11As shown, at this time, no plug block 7 is inserted into the jack 5. Therefore, under the elastic force of the third spring 15, the bearing plate 14 is located at the lowest point in the storage groove 13, which is restricted by the limiting groove 1301 and the convex plate 1401. At this time, the rotating rod 16 is located in the jack 5, and as Figure 12 shown, when the plug block 7 is pushed by the first spring 602 and inserted into the jack 5, the chamfer 701 will hit the rotating rod 16, and then the rotating rod 16 will gradually roll on the chamfer 701, thereby pushing the bearing plate 14 to compress the third spring 15 and finally retracting into the storage groove 13. During the insertion process of the plug block 7, it will be blocked by three rotating rods 16, so that the elastic force of the first spring 602 can be dispersed and absorbed, avoiding the direct impact of the plug block 7 on the jack 5 to generate noise, and avoiding the reverse transmission of the vibration generated after the impact of the plug block 7 to the first spring 602, protecting the plug block 7 and the first spring 602.

[0085] As Figures 1-8 shown, as a preferred embodiment of the present invention, a plurality of rollers 12 are rotatably installed at one end of the moving plate 802 close to the regular trapezoidal block 804 and one end of the plug block 7 close to the inverted trapezoidal block 4.

[0086] In the actual application of this embodiment, through the setting of the rollers 12, when the inverted trapezoidal block 4 descends, the plug block 7 will not directly abut against the inverted trapezoidal block 4, but the rollers 12 will abut against the inverted trapezoidal block 4. As the inverted trapezoidal block 4 descends, the rollers 12 will roll on the inverted trapezoidal block 4, thus changing the sliding friction between the plug block 7 and the inverted trapezoidal block 4 into rolling friction, thereby reducing the resistance of movement. Similarly, the frictional resistance between the moving plate 802 and the regular trapezoidal block 804 can also be reduced.

[0087] A detailed description of an embodiment of the present invention has been given above, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
