Description

Technical Field

[0001] This application relates to the field of die casting mold technology, and in particular to a die casting mold for rapid prototyping of precision hardware parts. Background Technology

[0002] Die casting molds are tools used to cast precision hardware parts. The basic process of die casting is as follows: molten metal is first cast into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools. This process eliminates shrinkage cavities and porosity defects in the blank and also makes the internal structure of the blank reach the forged state with broken grains.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, different die-casting molds need to be replaced when producing different models of hardware parts. However, some existing die-casting molds are fixed inside the machine, making the replacement process cumbersome and reducing die-casting efficiency.

[0004] Secondly, some die-casting molds are usually fixed in a simple way, which can lead to uneven impact forces on the mold, thereby accelerating the wear and damage of the mold, reducing the service life of the mold, and may also reduce the precision of the mold.

[0005] To address the aforementioned problems, the inventors have proposed a die-casting mold for rapid prototyping of precision hardware parts, which solves these problems. Summary of the Invention

[0006] In order to improve the problem of the cumbersome fixing method of existing die-casting molds, the purpose of this utility model is to provide a die-casting mold for rapid prototyping of precision hardware parts.

[0019] The lower surface of the upper mold 5 is provided with a lower mold 4, which can cooperate with the upper mold 5 to close the mold. A support mechanism 3 is fixedly installed on the outer surface of the lower mold 4, which can fix the lower mold 4.

[0020] The fixing mechanism 2 includes connecting blocks 24, which are fixedly installed on the lower surface of the housing 1 by bolts. The connecting blocks 24 are arranged in a rectangular array, which can increase the fixing effect of the fixing mechanism 2.

[0021] The connecting block 24 is fixedly installed on the lower surface of the housing 1. A support bolt 26 is fixedly installed on the bottom surface of the connecting block 24. The support bolt 26 is a standard part. A fixing plate 23 is movably sleeved on the outer surface of the support bolt 26, so that the fixing plate 23 can slide or rotate on the outer surface of the support bolt 26. A fixing nut 25 is threaded on the outer surface of the support bolt 26. The fixing nut 25 can cooperate with the support bolt 26 to form a threaded connection. The fixing nut 25 is located on the lower surface of the fixing plate 23, so that the fixing plate 23 can be fixed.

[0022] A mirror-distributed connecting plate 22 is fixedly installed at one end of the fixed plate 23. A pad 21 is fixedly and rotatably installed on the opposite side of the connecting plate 22. The pad 21 is hexagonal and can rotate between the connecting plates 22. The connecting plate 22 and the pad 21 are rotatably connected at their eccentric points, so that the height of the rotating pad 21 is different, thereby achieving the effect of adjusting the height of the fixed plate 23.

[0023] A contact block 27 is fixedly installed at the end of the fixing plate 23 away from the connecting plate 22. The top surface of the contact block 27 is in contact with the upper mold 5. The contact block 27 has the effect of increasing friction and preventing slippage, thereby fixing the upper mold 5.

[0024] The support mechanism 3 includes a support plate 33, which is a plate with a groove inside. Upright plates 36 are attached to the inner walls of both sides of the support plate 33, so that the upright plates 36 are attached to the inner walls of both sides of the support plate 33. The upright plates 36 are mirror-mounted on both sides of the lower mold 4, so that the upright plates 36 are fixedly connected to the lower mold 4.

[0025] Multiple first through slots 32 are mirror-arranged on both sides of the support plate 33. The first through slots 32 are mirror-arranged on both sides of the support plate 33. Fastening bolts 35 are slidably installed inside the first through slots 32, so that the fastening bolts 35 can slide inside the first through slots 32 and fix the support plate 33 and the upright plate 36.

[0026] The end of the fastening bolt 35 is provided with a rotating groove 34, through which the fastening bolt 35 can be rotated.

[0027] A fastening nut 31 is threaded onto the end of the fastening bolt 35 away from the support plate 33. The fastening nut 31 can be used in conjunction with the fastening bolt 35. The fastening nut 31 is slidably installed on the side of the upright plate 36 facing away from the support plate 33. A second through groove 37 is opened on the side of the upright plate 36 facing away from the support plate 33. The fastening nut 31 is slidably inserted into the second through groove 37, so that the fastening bolt 35 and the fastening nut 31 are slidably installed in the first through groove 32 and the second through groove 37 and threadedly connected, thereby fixing the support plate 33 and the upright plate 36.

[0028] Working principle: First, the housing 1 is installed on the die-casting machine. Then, the fixing mechanism 2 is installed on the lower surface of the housing 1 through the connecting block 24. Then, the die-casting machine can be started to descend, so that the housing 1 is fitted onto the outer surface of the upper mold 5. The upper mold 5 is fixed by using the fixing mechanism 2. The fixing plate 23 is rotated so that the contact block 27 is located on the side bottom surface of the upper mold 5. The pad 21 is rotated so that the pad 21 rotates inside the connecting plate 22 to adjust the height of the fixing plate 23. Then, the fixing nut 25 is tightened so that the fixing nut 25 rotates on the threaded surface of the support bolt 26, while pressing the fixing plate 23, so that the fixing plate 23 fixes the upper mold 5 through the contact block 27.

[0029] Then, the lower mold 4 is placed inside the support mechanism 3, and the upright plate 36 is fixed on both sides of the lower mold 4. At the same time, the upright plate 36 is in contact with the inner walls of both sides of the support plate 33. Then, the fastening bolt 35 is slid into the first through groove 32 and the second through groove 37. Then, the rotating groove 34 is turned by a tool to make the fastening bolt 35 cooperate with the fastening nut 31, so that the lower mold 4 can be fixed in the support mechanism 3 through the upright plate 36.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
