Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a metal injection and die casting integrated forming device. Background Art

[0002] The die-casting process is a process in which liquid metal is poured into a mold and then formed into a workpiece under certain pressure conditions. It is generally used to produce products with low strength, such as aluminum. Currently, most die-casting processes are carried out mechanically, using a robot to pick up the liquid metal and pour it into the injection mechanism.

[0003] For example, the public document with application number 202120665600.5 discloses an integrated aluminum alloy injection molding and die-casting molding equipment. The utility model realizes the control of the liquid spoon by setting a flipping mechanism and cooperating with the electromagnetic mechanism and the reset assembly, thereby avoiding close contact with the metal liquid and resulting in a reduction in service life. However, when the metal injection molding and die-casting integrated molding device is used to close the mold, the upper and lower molds are directly pushed and squeezed together by the cylinder. The upper and lower molds are directly squeezed and fitted, and the impact pressure and vibration force generated may cause wear of the mold, thereby affecting the service life of the mold and the sealing of the mold.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a metal injection molding and die-casting integrated molding device is proposed. Utility Model Content

[0007] Preferably, the buffer member comprises a guide rod fixedly installed above the inner surface of the sink, and two extrusion plates are slidably provided on both sides of the surface of the guide rod.

[0008] Preferably, the buffer component further comprises a movable rod rotatably mounted on the upper end of the extrusion plate, the movable rod is tilted toward the middle and is rotatably provided with a pressure plate via the same rotating shaft seat.

[0009] Preferably, the buffer also includes a thrust spring sleeved on the outside of the guide rod on the opposite side of the extrusion plate, and a damping spring rod is fixedly installed below the opposite side of the surface of the extrusion plate, and the damping spring rod is composed of a damper and a spring.

[0010] Preferably, an upper mold is fixedly disposed at the middle portion of the opposite end of the side plate, and an injection port is opened above the surface of the upper mold.

[0012] Preferably, the lower edge of the surface of the upper mold is evenly distributed and fixed with limit blocks at positions relative to the positioning grooves, and the limit blocks and the positioning grooves are both configured as inclined surfaces that match each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the push plate, buffer, guide rod, extrusion plate, movable rod, pressure plate, thrust spring and damping spring rod to buffer the impact force of the upper mold and the lower mold, so that the mold is softer when the mold is closed, avoiding high pressure impact and causing mold damage, reducing the impact and vibration caused by contact when the mold is closed, protecting the entire device, and prolonging the service life of the injection mold;

[0015] 2. The utility model provides a limit block and a positioning groove. When the upper mold and the lower mold are joined, the limit block will be inserted into the positioning groove.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, a metal injection molding and die-casting integrated molding device includes a base 1, a cylinder 2 is fixedly installed on the left and right sides above the outer surface of the base 1, a side plate 3 is fixedly installed on the upper end of the cylinder 2, a push plate 4 is fixedly installed in the middle below the surface of the side plate 3, and a sink groove 5 is opened on the left and right sides above the surface of the base 1, and a buffer member 6 is arranged inside the sink groove 5.

[0023] By adopting the above technical solution, the push plate 4 is convexly arranged, and will push the buffer member 6 when the mold is closed. The buffer member 6 can be used to buffer the impact force of the mold closing, making the mold softer when the mold is closed, avoiding high-pressure impact and causing damage to the mold.

[0024] Furthermore, the buffer member 6 includes a guide rod 601 fixedly installed above the inner surface of the sink 5 , and two extrusion plates 602 are slidably provided on both sides of the surface of the guide rod 601 .

[0025] By adopting the above technical solution, the guide rod 601 makes the sliding of the extrusion plate 602 more stable.

[0026] Furthermore, the buffer member 6 also includes a movable rod 603 rotatably mounted on the upper end of the extrusion plate 602 . The movable rod 603 is tilted toward the middle and is rotatably provided with a pressure plate 604 via the same rotating shaft seat.

[0027] By adopting the above technical solution, when the mold is closed, the pressure plate 604 is first squeezed by the push plate 4, so that the movable rod 603 pushes the squeezing plate 602 to both sides.

[0028] Furthermore, the buffer 6 also includes a thrust spring 605 sleeved on the outside of the guide rod 601 on the opposite side of the extrusion plate 602, and a damping spring rod 606 is fixedly installed below the opposite side of the surface of the extrusion plate 602, and the damping spring rod 606 is composed of a damper and a spring.

[0029] By adopting the above technical solution, the extrusion plate 602 moves to both sides, which will squeeze the thrust spring 605 and the damping spring rod 606 at the same time, and use the thrust spring 605 and the damping spring rod 606 to buffer the impact force of the upper mold 7 pressing down.

[0030] like Figure 2 and Figure 4 As shown, an upper mold 7 is fixedly disposed at the middle of the opposite end of the side plate 3 , and an injection port 8 is opened above the surface of the upper mold 7 .

[0031] By adopting the above technical solution, the molding material can be injected into the mold after the mold is closed by using the injection port 8.

[0032] Furthermore, a lower mold 9 is fixedly installed in the middle of the upper surface of the base 1, and positioning grooves 11 are evenly distributed around the upper surface of the lower mold 9. A limiting block 10 is evenly distributed and fixedly installed on the lower edge of the surface of the upper mold 7 at a relative position to the positioning groove 11, and the limiting block 10 and the positioning groove 11 are both set to be inclined surfaces that match each other.

[0033] By adopting the above technical solution, when the upper mold 7 and the lower mold 9 are joined together, the limit block 10 will be inserted into the positioning groove 11, and the corresponding inclined surfaces between the limit block 10 and the positioning groove 11 can be used to correct the joining of the upper mold 7 and the lower mold 9.

[0034] Working principle: When using the metal injection molding and die-casting integrated molding device, first, the side plate 3 is pulled downward by the cylinder 2, driving the upper mold 7 to move downward and engage with the lower mold 9. When the molds are engaged, the protruding push plate 4 will follow and move downward, pushing the pressure plate 604 to move downward, thereby pushing the movable rod 603 to expand to both sides through the pressure plate 604, pushing the extrusion plate 602 to slide along the guide rod 601, and then simultaneously squeezing the thrust spring 605 and the damping spring rod 606, and utilizing the thrust spring 605 and the damping spring rod 606 to buffer the impact force of the upper mold 7 being pressed downward. When the upper mold 7 contacts the lower mold 9, the limit block 10 will be inserted into the positioning groove 11. By utilizing the corresponding inclined surfaces between the limit block 10 and the positioning groove 11, the engagement of the upper mold 7 and the lower mold 9 can be corrected, thereby improving the accuracy of the engagement. This is the working principle of the metal injection molding and die-casting integrated molding device.
