On the other side surface of the demoulding plate, a plurality of mating concave hole grooves matching the heads of the mold demoulding connecting rods are provided corresponding to the first through holes of the demoulding transition plate. The mating concave hole grooves on the other side surface of the demoulding plate are set as stepped holes communicating with the one side surface of the demoulding plate via second through holes. A threaded hole is formed at the top end of the head, and a bolt is connected to the threaded hole from the one side surface of the demoulding plate via the second through hole. The demoulding oil cylinder is of a double-sided piston rod type, with one end of the piston rod fixed on the back surface of the movable template of the high-pressure casting machine, and the other end of the piston rod fixed on the demoulding plate. Among them, in addition to the demoulding function, the piston rod also plays a guiding role in the demoulding action of the demoulding plate.

[0005] Preferably, the guide rail includes an L-shaped demoulding pressing plate installed and fixed at the corner position on the other side of the demoulding plate.

Moreover, any numerical range stated herein is intended to include all sub-ranges subsumed therein. The numerical range represented by "numerical value A to numerical value B" means a range including the endpoint numerical values A and B. Those skilled in the art can understand that the terms "first", "second", "step", etc. in the present invention are only used to distinguish different steps, devices or modules, etc., and neither represent any specific technical meaning nor indicate an inevitable logical sequence between them. For example, step two and step three can be swapped or run in parallel.

[0024] According to an embodiment of the present invention, there is provided a high-pressure die casting machine rapid demolding and ejection mechanism and a high-pressure die casting machine having the demolding and ejection mechanism, as Figure 1As shown in the figure, the demolding and ejection mechanism includes: a demolding plate 1; two demolding oil cylinders 2 fixedly installed in parallel on one side of the demolding plate 1; a demolding transition plate 5 slidably installed on the other side of the demolding plate 1 via guide rails; a positioning oil cylinder 7 for driving the demolding transition plate 5 to slide relative to the demolding plate 1; and a mold demolding connecting rod 6 with one end detachably locked to the demolding transition plate 5 and the other end connected to the mold to be demolded. Among them, a plurality of first through holes 9 in the shape of, for example, an 8 character formed by the communication of a small hole part 13 and a large hole part 14 are provided on the demolding transition plate 5. An adjacent part at one end of the mold demolding connecting rod 6 is formed with: a head 16 with an outer diameter matching that of the large hole part 14 and a necking part 15 with an outer diameter matching that of the small hole part 13. A plurality of mating concave hole grooves 19 matching the heads 16 of the mold demolding connecting rod 6 are provided on the other surface of the demolding plate 1 corresponding to the first through holes 9 of the demolding transition plate 5.

[0025] Preferably, the demolding oil cylinder 2 is of a double-sided (also known as double-headed) piston rod type. One side ( Figure 1 the right side in the figure) of the piston rod 8 is fixed to the back surface of the movable template of the high-pressure casting machine, and the other side ( Figure 1 the left side in the figure) of the piston rod 10 is fixed to the demolding plate 1 (see Figure 8 ).

[0026] Preferably, the guide rails include 4 groups of "L-shaped" (also known as "factory-shaped") demolding pressing plates 3 installed and fixed at the four corner positions on the other side of the demolding plate 1 through bolts 4, so as to form a guide rail part between the demolding pressing plates 3 and the demolding plate 1 that allows the demolding transition plate 5 to slide along the surface of the demolding plate 1 in a clearance fit manner.

[0027] Preferably, a step part 11 corresponding to the "L-shaped" shape is formed at the edge part of the demolding transition plate 5 to cooperate with the guide rail part.

[0028] Preferably, a termination limiting part 12 is provided between two adjacent step parts 11 in the sliding direction of the demolding transition plate 5. The width of the termination limiting part 12 is smaller than the distance between the two step parts 11 by a predetermined distance, thereby limiting the sliding stroke of the demolding transition plate 5.

[0029] A window part 17 is also formed at the central side of the demolding transition plate 5 for accommodating, for example, a positioning oil cylinder 7 fixedly installed on the other surface of the demolding plate 1 through bolts. The two end planes of the double-headed piston rod of the positioning oil cylinder 7 are used to push the demolding transition plate 5 to reciprocate along the surface of the demolding plate 1 in opposite directions.

[0030] A recessed part 18 is also formed at the relative edge side of the demolding transition plate 5 to avoid the piston rod 10 on the other side of the demolding oil cylinder 2. At the same time, the weight of the demolding transition plate 5 can be reduced, and a plurality of first through holes 9 can be opened on the demolding transition plate 5 as much as possible.

[0031] The first through hole 9 can serve as the installation card slot for the mold demolding link 6. The necking part 15 of the mold demolding link 6 correspondingly forms an annular card slot. After the head 16 of the mold demolding link 6 passes through the large hole part 14 of the first through hole 9 and is inserted into the mating concave hole groove 19 of the demolding plate 1, the positioning oil cylinder 7 drives the demolding transition plate 5 to slide along the plate surface of the demolding plate 1, so that the large hole part 14 of the demolding transition plate 5 moves away from the necking part 15, and at the same time the small hole part 13 is clamped to the necking part 15, thereby clamping the mold demolding link 6 to the demolding transition plate 5 and the demolding plate 1.

[0032] In this way, after the mold demolding link 6 is locked by the demolding transition plate 5, the demolding oil cylinder 2 drives the demolding plate 1 to perform the casting demolding action of the high-pressure casting machine, and the demolding force is transmitted to the casting through the demolding link 6, and the casting is ejected by the demolding link 6.

[0033] When it is necessary to disassemble the demolding link 6, or when it is necessary to change the clamping position of the demolding link 6 to adapt to different molds, the positioning oil cylinder 7 drives the demolding transition plate 5 in the reverse direction to release the clamping between the small hole part 13 and the necking part 15, so that the necking part 15 moves relatively into the large hole part 14, so that the demolding link 6 can be pulled out from the mating concave hole groove 19 of the demolding plate 1.

[0034] In this way, through the reciprocating movement of the demolding transition plate 5, the rapid fixation of the demolding link 6 can be realized. And when the demolding transition plate 5 moves in one direction, the demolding link 6 is no longer clamped by the demolding transition plate 5, and the demolding link 6 can be removed together with the die-casting machine mold.

[0035] Optionally, in normal production, the front end of the demolding link 6 can be connected to the mold by threads, and the rear end is set as a T-shaped head structure such as the above-mentioned head 16 and necking part 15. The purpose of the reciprocating movement of the demolding transition plate 5 is to hook the T-shaped head of the demolding link 6 to fix the demolding link 6.

[0036] The arrangement of the mating concave hole groove 19 can be preset according to production practice, and different arrangements and installation methods for different molds can be comprehensively considered and set.

[0037] As Figure 9 shown, the demolding oil cylinder 2 itself is both an actuator and a guiding mechanism, that is, the piston rod 8 has a guiding function (see the part indicated by the reference numeral 31 in Figure 9 ), the demolding oil cylinder 2 is fixedly connected to the demolding plate 1 (see the part indicated by the reference numeral 32 in Figure 9 ), and the piston rod 8 is fixedly connected to the moving template 30 of the high-pressure casting machine (see the part indicated by the reference numeral 33 in Figure 9 ). In this way, it is possible to realize the execution of actions by using at least two oil cylinders (demolding oil cylinders 2); the piston rod 8 can be in a double-ended form (double-sided piston rod type).

[0038] As Figure 10 shown, a threaded hole 34 is formed at the top end of the head 16 of the mold demolding link 6, and a second through hole 35 penetrating the demolding plate 1 is formed in communication with the position of the concave hole groove 19 of the demolding plate 1. Thus, the bolt 36 can be connected to the threaded hole 34 from one side surface of the demolding plate 1 ( Figure 10 the right side in the figure), via the second through hole 35, thereby realizing the fixed connection of the head 16. Thus, when a positioning oil cylinder 7 on the other side surface of the demolding plate 1 ( Figure 10 the left side in the figure) fails, etc., the fixing of the mold demolding link 6 can still be reliably realized, and the centering or parallelism between the mold demolding links 6 can be assisted in determination by the lengths of the second through hole 35, the bolt 36, and the washer (not shown). Here, the concave hole groove 19 and the second through hole 35 are formed as stepped holes.

[0039] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise clearly and specifically defined. Unless otherwise clearly specified and defined, terms such as "mounted", "connected", "connected to", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. Although the present invention has been described with reference to various specific embodiments, it should be understood that modifications can be made within the spirit and scope of the described inventive concept. Therefore, it is intended that the present invention is not limited to the described embodiments, but will have the full scope defined by the language of the appended claims.
