Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-casting machine technology, and specifically to a thrust device for a die-casting machine. Background Technology
[0002] Die casting is a process in which molten metal is poured into a die-casting mold cavity at high pressure and speed, and then solidified under high pressure to form a metal die casting. It is the most efficient metal casting method. The significant characteristics of metal die casting are: it can form complex-shaped, thin-walled non-ferrous metal structural parts. It is a high-efficiency, high-precision, highly interchangeable, and low-consumption precision parts forming technology. Die casting machines are among the most common pieces of equipment in die casting production.
[0003] In the prior art, die-casting machines rely on the force amplification effect and self-locking characteristics of the toggle mechanism for mold clamping. For example, Chinese invention application No. 202311793905.4 (publication number CN117862464A) discloses "A mold clamping structure for a die-casting machine", which includes a tie rod and a head plate, a second plate, and a tail plate connected sequentially to the tie rod. A linkage mechanism is connected between the second plate and the tail plate. A thrust seat is provided on the linkage mechanism, and a mold clamping cylinder is connected to the thrust seat. The head plate includes a guide plate and a fixed mold connected together. The guide plate has several guide parts for changing the direction of mold clamping force transmission. The second plate includes a transmission plate and a moving mold connected together. The fixed mold and the moving mold cooperate to form a mold clamping structure. The transmission plate has several transmission parts for changing the direction of mold clamping force transmission. The aforementioned prior art uses a thrust seat to press the fixed mold and the moving mold together to form a mold closing structure. That is, the mold locking cylinder pushes the thrust seat to move axially, and the thrust seat drives the connecting rod to move, thereby moving the moving mold. The stability of the thrust result is insufficient. Some prior art uses the method of increasing the thickness and weight of the connecting rod to improve stability, but this method will increase the weight of the thrust structure and increase the cost of production and assembly. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a die-casting machine thrust device with good stability and light weight, in view of the above-mentioned technical status.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a die-casting machine thrust device, including a base;
[0006] The first linkage group has two symmetrically distributed links, and the aforementioned first linkage group is rotatably connected to the base;
[0007] The thrust seat is mounted on the base and can move axially relative to the base;
[0008] The second linkage group comprises two symmetrically distributed links, each of which is rotatably connected to the first linkage group and the thrust seat; characterized in that:
[0009] The second linkage group includes two first links and a second link disposed between the two first links, wherein the width of the second link is greater than the width of the first link;
[0010] The base is provided with two spaced-apart brackets, each of which is provided with a guide post. The two ends of the thrust seat along the length direction form guide holes that are fitted around the outer periphery of the guide post.
[0011] Preferably, the first linkage group includes two third linkages, both of which are located between the first linkage and the second linkage.
[0012] Preferably, the first link and the third link are rotatably connected by a pin; the second link and the third link are rotatably connected by a pin.
[0013] Preferably, the thrust base is provided with mounting holes for installing a thrust pump.
[0014] In order to achieve rotatable connection with the second link, preferably, the thrust seat extends outward on both sides along the width direction to form a plurality of first mounting seats that are rotatably connected to the second link group.
[0015] To further reduce the weight of the thrust device, preferably, the thrust base is provided with a plurality of symmetrically distributed weight-reduction grooves.
[0016] Preferably, the base extends upward to form a plurality of second mounting seats for rotatable connection with the first linkage group.
[0017] Compared with the prior art, the advantages of this utility model are as follows: the second linkage group includes two first linkages and a second linkage disposed between the two first linkages, and the width of the second linkage is greater than the width of the first linkage. The wider second linkage drives the first linkage group to rotate more smoothly, which enhances the operational stability of the thrust device, reduces the weight of the thrust device, increases production efficiency, and reduces the deformation of the second linkage group during operation. Furthermore, since the two second linkage groups are symmetrically distributed, the thicker second linkage does not affect the uniform force on the thrust seat. The guide hole and guide post can guide the running direction of the thrust device during the mold closing process. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1-3 The diagram shows a preferred embodiment of the present invention. The die-casting machine thrust device of the present invention can be applied to a mold-closing structure. The die-casting machine thrust device includes a base 1, a first connecting rod group 2, a thrust seat 3, and a second connecting rod group 4.
[0023] The base 1 has two spaced-apart brackets 11, each bracket 11 having a guide post 12. The thrust seat 3 has guide holes 32 at both ends along its length, which are fitted onto the outer periphery of the guide post 12. The base 1 extends upward to form multiple second mounting seats 13 for rotatable connection with the first connecting rod assembly 2.
[0024] The first linkage group 2 has two links that are symmetrically distributed. The first linkage group 2 is rotatably connected to the base 1. The first linkage group 2 is provided with a connection hole 211 for connecting to external equipment.
[0025] The thrust seat 3 is mounted on the base 1 and can move axially relative to the base 1. The thrust seat 3 has a mounting hole 31 in its center for mounting the thrust pump, thus enabling the thrust seat 3 to move vertically. The thrust seat 3 has multiple symmetrically distributed weight-reducing grooves 34 and weight-reducing holes. The thrust seat 3 extends outwards on both sides along its width to form multiple first mounting seats 33 that are rotatably connected to the second connecting rod assembly 4. The thrust pump is generally a mold-locking cylinder.
[0026] The second linkage group 4 has two members symmetrically distributed, each rotatably connected to the first linkage group 2 and the thrust seat 3. The second linkage group 4 includes two first links 41 and a second link 42 located between the two first links 41, with the thickness of the second link 42 greater than that of the first link 41. The first linkage group 2 includes two third links 21, each located between the first link 41 and the second link 42. The first link 41 and the third link 21 are rotatably connected by a pin; the second link 42 and the third link 21 are also rotatably connected by a pin. Each third link 21 has a connection hole 211 for connecting to external equipment.
[0027] The workflow of this embodiment is as follows:
[0028] The thrust pump installed in the mounting hole 31 in the middle of the thrust base 3 drives the thrust base 3 to move upward. The upward movement of the thrust base 3 drives the second link group 4 to rotate. The rotation of the second link group 4 drives the first link group 2 to rotate, thereby driving the external equipment located in the connection hole 211 of the first link group 2 to move.
