Description

Technical Field

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

[0002] Nonferrous metal high-pressure casting is a manufacturing technology that rapidly injects molten metal (such as aluminum alloy, magnesium alloy, copper alloy, etc.) into a mold cavity under high pressure conditions so that it solidifies and forms in a short time. This process usually occurs under high pressure. The molten metal fills the mold at an extremely fast speed and can solidify in 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 can easily cause the mold gap to expand, especially the movable mold part, because it is relatively active and lacks sufficient rigid support, it is easy to be deformed by force, and even slightly separated, seriously affecting the dimensional accuracy and surface quality of the casting. In addition, the rapid expansion force of the molten metal in the cavity causes a strong adsorption force on the movable mold and the fixed mold during molding, and the pulling force of the casting is extremely strong when the mold is separated, especially for large and complex castings. This force is enough to cause a small but fatal deformation or offset of the fixed mold, destroying the original precise positioning of the mold. Based on this, the present invention purposely provides a non-ferrous metal high-pressure casting process and device that can overcome the deformation and offset of the movable 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 to solve the technical problems in the prior art in view of the deficiencies in the prior art.

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

[0006] A nonferrous metal high pressure casting process comprises the following steps:

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

[0008] Step S2: Then, a release agent is applied to the inner cavities of the fixed mold and the movable mold;

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

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

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

[0012] Step S6: releasing the locking state of the inverted trapezoidal block through the reset component, and the reset component causes the lower pressing plate to press the extension block downward through the lower pressing component;

[0013] Step S7: Separate the fixed mold from the movable mold and take out the casting.

[0014] As a further solution of the present invention: the step S3 specifically comprises the following steps:

[0015] Step S31: The movable mold is driven to descend by the driving source, at which time the guide rod is gradually inserted into the guide hole, and the inverted trapezoidal block is synchronously descended and abuts against the insertion block;

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

[0017] Step S33: When the movable mold and the fixed mold are closed, the socket and the slide groove are aligned, and the first spring pushes the plug block to be inserted into the socket, thereby locking the inverted trapezoidal block. In the process of inserting the plug block into the socket, the plug block is subjected to the unloading force of multiple rotating rods to prevent the plug block from generating excessive impact in the socket.

[0018] As a further solution of the present invention: the step S6 specifically comprises the following steps:

[0019] Step S61: the preload force of the second spring causes the movable plate to abut against the positive trapezoidal block, and the positive trapezoidal block is driven to rise by the output source, and the rising positive trapezoidal block squeezes the movable plate to move;

[0020] Step S62: The movement of the moving plate drives the insert block to move synchronously through the sliding portion of the insert block located in the groove, so that the insert block is retracted from the insertion hole back into the slide groove, releasing the locking state of the inverted trapezoidal block;

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

[0025] A fixed block, which is fixedly mounted on the casting table and has a slide slot therein, in which an insert block is slidably mounted, and the insert block is connected to the slide slot through a first spring. When the inverted trapezoidal block descends, it abuts and compresses the insert block to move into the slide slot, until the inverted trapezoidal block descends until the insertion hole is aligned with the slide slot, and the first spring pushes the slide slot to insert into the insertion hole;

[0026] The reset component is arranged on the casting table. Before the fixed mold and the movable mold are separated, the reset component drives the plug block to move out of the plug hole. At the same time, the reset component drives the lower pressure plate to descend through the lower pressure component until the lower pressure plate abuts the extension block. At this time, the driving source drives the movable mold to rise.

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

[0028] As a further solution of the present invention: the pressing assembly includes a square vertical groove, a square slider, an oblique groove and a round rod, the square vertical groove is opened on the fixed frame, the oblique groove is opened on the movable plate, it is arranged obliquely, and its horizontal height away from one end of the regular trapezoidal block is higher than its horizontal height close to one end of the regular trapezoidal block, the square slider is slidably installed in the square vertical groove, the round rod is slidably installed in the oblique groove, one end of which is fixedly connected to the square slider, and the other end of which is fixedly connected to the pressing plate.

[0029] As a further solution of the present invention: a chamfer is provided on the plug block, and three equally spaced storage grooves are provided on the top plate of the socket, each storage groove is connected to a supporting plate via a third spring, a limiting groove is provided in the storage groove, a convex plate is fixedly installed on the supporting plate, and the convex plate is slidably installed in the limiting groove, the supporting plate is slidably connected to the storage groove, and a rotating rod is rotatably installed on the bottom end, and the rotating rod abuts against the chamfer.

[0030] As a further solution of the present invention: a plurality of rollers are rotatably mounted on one end of the movable plate close to the regular trapezoidal block and one end of the insert block close to the inverted trapezoidal block.

[0031] Beneficial effects of the present invention:

[0032] 1. In the present invention, as the movable mold and the fixed mold are molded together, the inverted trapezoidal block gradually cooperates with the plug block and deepens. Finally, the plug block is inserted into the insertion hole on the inverted trapezoidal block to complete the locking of the inverted trapezoidal block, thereby ensuring the rigid connection between the movable mold and the fixed mold when they are molded together, and avoiding the high pressure when injecting the molten metal to cause the mold to deviate. Before mold separation, the reset component drives the plug block to move out of the insertion hole, thereby unlocking the inverted trapezoidal block. In the unlocking process, the reset component drives the lower pressure plate to descend and abut against the extension block through the lower pressure component, so that the fixed mold overcomes the strong adsorption force after the high-pressure casting is formed. When the movable mold moves upward to implement mold separation, the force that would originally pose a threat to the fixed mold is effectively dispersed, ensuring that the fixed mold is always stable in place, and avoiding deformation and damage caused by mutual traction between the molds;

[0033] 2. In the present invention, when the plug is pushed by the first spring to be 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 retract into the storage groove. The plug will be blocked by the three rotating rods during the insertion process, so that the elastic force of the first spring can be dispersed and absorbed, and the plug can be prevented from directly hitting the insertion hole to generate noise, and the vibration generated by the plug after the collision can be prevented from being reversely transmitted to the first spring, thereby protecting the plug and the first spring;

[0034] 3. In the present invention, by setting the roller, when the inverted trapezoidal block descends, the insert block will not directly abut against the inverted trapezoidal block, but the roller will abut against the inverted trapezoidal block. As the inverted trapezoidal block descends, the roller will roll on the inverted trapezoidal block, thus converting the sliding friction between the insert block and the inverted trapezoidal block into rolling friction, thereby reducing the resistance to movement. Similarly, the friction resistance between the moving plate and the positive trapezoidal block can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1-Figure 13 As shown, the present invention is a non-ferrous metal high pressure casting process, comprising the following steps:

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

[0053] Step S2: Then, a release agent is applied to the inner mold cavities of the fixed mold 2 and the movable mold 3;

[0054] Step S3: closing the fixed mold 2 and the movable mold 3, and locking the inverted trapezoidal block 4;

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

[0056] Step S5: waiting 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 component 8, and the reset component 8 causes the lower pressing plate 10 to press the extension block 11 downwards through the lower pressing component 9;

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

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

[0060] Step S31: The movable mold 3 is driven down by the driving source, and the guide rod 301 is gradually inserted into the guide hole 201, and the inverted trapezoidal block 4 is synchronously lowered and abuts against the insert block 7;

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

[0062] Step S33: When the movable mold 3 and the fixed mold 2 are closed, the socket 5 is aligned with the slide groove 601, and the first spring 602 pushes the plug block 7 to be inserted into the socket 5, thereby locking the inverted trapezoidal block 4, and the plug block 7 is subjected to the unloading force of multiple rotating rods 16 during the insertion process of the socket 5, preventing the plug block 7 from generating excessive impact in the socket 5.

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

[0064] Step S61: the preload force of the second spring 803 causes the moving plate 802 to abut against the positive trapezoidal block 804, and the positive trapezoidal block 804 is driven to rise by the output source, and the rising positive trapezoidal block 804 squeezes the moving plate 802 to move;

[0065] Step S62: The movement of the moving plate 802 drives the insert block 7 to move synchronously through the sliding portion of the insert block 7 located in the groove 805, so that the insert block 7 is retracted from the insertion hole 5 back into the slide groove 601, and the locking state of the inverted trapezoidal block 4 is released;

[0066] Step S63 : The movement of the moving plate 802 causes the inclined slot 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 slot 901 , thereby causing the lower pressing plate 10 to descend and abut against the extension block 11 .

[0067] See also Figure 1-Figure 13 As shown, the present invention is 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 comprises:

[0068] A casting table 1, on which a fixed mold 2 is fixedly installed, and a movable mold 3 is slidably installed, the movable mold 3 is located above the fixed mold 2, is connected to the feeding assembly, and is driven by a driving source to rise and fall, the fixed mold 2 is fixedly installed with two symmetrically arranged extension blocks 11, and the casting table 1 is slidably installed with two lower pressure plates 10, the lower pressure plates 10 are located above the extension blocks 11, and are driven by the reset assembly 8 through the lower pressure assembly 9 to rise and fall;

[0069] Inverted trapezoidal blocks 4, two inverted trapezoidal blocks 4 are fixedly mounted on the movable mold 3, and the two inverted trapezoidal blocks 4 are symmetrically arranged, the connecting line of the two inverted trapezoidal blocks 4 is perpendicular to the connecting line of the two extension blocks 11, and the inverted trapezoidal blocks 4 are provided with a plug hole 5;

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

[0071] The reset component 8 is arranged on the casting table 1. Before the fixed mold 2 and the movable mold 3 are separated, the reset component 8 drives the insert block 7 to move out of the insertion hole 5. At the same time, the reset component 8 drives the lower pressure plate 10 to descend through the lower pressure component 9 until the lower pressure plate 10 abuts against the extension block 11. At this time, the driving source drives the movable mold 3 to rise.

[0072] In one case of the present embodiment, guide holes 201 are opened at the four corners of the fixed mold 2, and guide rods 301 are fixedly installed at the four corners of the movable mold 3. Each guide rod 301 is slidably matched with a guide hole 201. The driving source can be an electric cylinder, a hydraulic rod and other components, and other mechanisms that can realize lifting and lowering movements can also be selected. This embodiment does not make specific restrictions here. The feeding component can be a die-casting machine, a plunger injection unit and other components. This embodiment does not make specific restrictions here.

[0073] The working principle of the present invention is as follows: firstly, 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. In this way, the raw materials are prepared, and then a release agent is applied to the mold cavities of the fixed mold 2 and the movable mold 3, and then the movable mold 3 is driven down by a driving source to close the mold. During the 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 movable mold 3 descends, Figure 2 As shown, the inverted trapezoidal block 4 will gradually descend and squeeze the insert block 7 to move into the slide groove 601, and then Figure 3 As shown, when the movable mold 3 and the fixed mold 2 are molded together, the insertion hole 5 is aligned with the slide groove 601, and the first spring 602 pushes the plug block 7 to be inserted into the insertion hole 5, thereby locking the inverted trapezoidal block 4. At this time, the feeding component presses the metal liquid into the cavity formed between the fixed mold 2 and the movable mold 3 through high pressure. The metal liquid solidifies rapidly under pressure to form the shape of the casting. The locking of the inverted trapezoidal block 4 greatly enhances the rigidity of the movable mold 3, so that even in the face of extreme internal pressure, the fixed mold 2 and the movable mold 3 can still maintain a perfect fit, avoiding mold separation due to pressure reaction;

[0075] Since the casting is formed under high pressure, it has a strong adsorption force on the mold cavities of the fixed mold 2 and the movable mold 3. When the movable mold 3 rises, the fixed mold 2 tends to rise through the adsorption force of the molded casting on the fixed mold 2. Therefore, before the mold is separated, Figure 4 As shown, the insert block 7 is driven out of the insertion hole 5 by the reset component 8, thereby unlocking the inverted trapezoidal block 4, and in the unlocking process, the reset component 8 drives the lower pressure plate 10 to descend through the lower pressure component 9, thereby abutting against the extension block 11. At this time, the movable mold 3 is driven to rise by the driving source to perform mold separation. The lower pressure plate 10 applies downward pressure to the extension block 11, so that the fixed mold 2 overcomes the strong adsorption force after high-pressure casting. When the movable mold 3 moves upward to implement mold separation, the force that would originally pose a lifting threat to the fixed mold 2 is effectively dispersed, ensuring that the fixed mold 2 is always stable in place, avoiding deformation and damage caused by mutual traction between molds.

[0076] like Figure 5-Figure 6As shown, as a preferred embodiment of the present invention, the reset assembly 8 includes a fixed frame 801, a movable 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 movable plate 802 is slidably installed on the fixed frame 801, and it 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 it is driven by an output source to rise and fall, the groove 805 is opened on the movable plate 802, the connecting block 806 is slidably installed in the groove 805, and it is fixedly connected to one end of the plug block 7 away from the socket 5, when the regular trapezoidal block 804 rises, it squeezes the movable plate 802 to move away from the axis of the regular trapezoidal block 804, and at this time the movable plate 802 compresses the second spring 803.

[0077] In one case of this embodiment, the output source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0078] In practical application, if Figure 8 As shown, due to the position restriction of the connecting block 806 in the groove 805, when the movable plate 802 moves toward the fixed frame 801, it will drive the connecting block 806 and the plug block 7 to move synchronously, so that the plug block 7 compresses the first spring 602 and shrinks back into the slide groove 601. This process is the process in which the positive trapezoidal block 804 rises and squeezes the movable plate 802 to move, thereby driving the plug block 7 to move out of the insertion hole 5, thereby unlocking the inverted trapezoidal block 4. After the inverted trapezoidal block 4 rises, the positive trapezoidal block 804 drops to its original position. At this time, the second spring 803 and the first spring 602 will jointly push the movable plate 802 and the plug block 7 back to their original positions, that is, Figure 4 Back to Figure 1 Status;

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

[0080] like Figure 5-Figure 7As shown, as a preferred embodiment of the present invention, the pressing 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 opened on the fixed frame 801, the inclined groove 903 is opened on the movable plate 802, which is arranged obliquely, and the horizontal height of one end away from the regular trapezoidal block 804 is higher than the horizontal height of one end close to the regular trapezoidal block 804, the square slider 902 is slidably installed in the square vertical groove 901, the round rod 904 is slidably installed in the inclined groove 903, one end of which is fixedly connected to the square slider 902, and the other end of which is fixedly connected to the pressing plate 10.

[0081] In one case of this embodiment, if Figure 5 As shown, at this time, the square slider 902 is located above the square vertical groove 901. In fact, at this time, the position of the inclined groove 903 on the round rod 904 is as shown in FIG. Figure 8 As shown, when the positive trapezoidal block 804 rises to squeeze the moving plate 802 to move, the movement of the moving plate 802, on the one hand, causes the insert block 7 to move into the slide groove 601, thereby unlocking the inverted trapezoidal block 4, and on the other hand, the movement of the moving plate 802 causes the inclined groove 903 to drive the round rod 904 to move, and the square vertical groove 901 restricts the moving direction of the square slider 902, causing the square slider 902 to descend, so that the lower pressing plate 10 will descend to abut against the extension block 11. Figure 6 As shown, the square design of the square vertical groove 901 and the square slider 902 prevents the lower pressure plate 10 from flipping over, ensures that the lower pressure plate 10 can be fully abutted against the extension block 11, and fully absorbs the upward force of the extension block 11 when the mold is separated. Such a design can link the operations of unlocking the inverted trapezoidal block 4 and pressing down the extension block 11, ensuring the effect while simplifying the operation.

[0082] like Figure 8-Figure 13 As shown, as a preferred embodiment of the present invention, a chamfer 701 is provided on the plug block 7, and three equally spaced receiving grooves 13 are provided on the top plate of the socket 5, each receiving groove 13 is connected to a supporting plate 14 via a third spring 15, a limiting groove 1301 is provided in the receiving groove 13, a convex plate 1401 is fixedly mounted on the supporting plate 14, and the convex plate 1401 is slidably mounted in the limiting groove 1301, the supporting plate 14 is slidably connected to the receiving groove 13, and a rotating rod 16 is rotatably mounted at the bottom end thereof, and the rotating rod 16 abuts against the chamfer 701.

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

[0084] In practical application, if Fig.11As shown, at this time, there is no insert block 7 inserted in the jack 5, so under the elastic force of the third spring 15, the bearing plate 14 is located at the lowest point in the receiving groove 13, which is limited by the limit groove 1301 and the convex plate 1401. At this time, the rotating rod 16 is located in the jack 5, and Fig.12 As shown, when the plug block 7 is pushed by the first spring 602 to be inserted into the socket 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 supporting plate 14 to compress the third spring 15 and finally retract into the receiving groove 13. The plug block 7 will be blocked by the three rotating rods 16 during the insertion process, which can disperse and absorb the elastic force of the first spring 602, avoid the plug block 7 directly hitting the socket 5 to generate noise, and avoid the vibration generated by the plug block 7 after the collision to be transmitted back to the first spring 602, thereby protecting the plug block 7 and the first spring 602.

[0085] like Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, one end of the movable plate 802 close to the regular trapezoidal block 804 and one end of the insert block 7 close to the inverted trapezoidal block 4 are both rotatably mounted with a plurality of rollers 12 .

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

[0087] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
