Description

Technical Field

[0001] The utility model relates to the technical field of mold accessories, in particular to a highly efficient die-casting mold replacement device. Background Art

[0002] At present, the moving and fixed modules are respectively lifted by an overhead crane and installed on the moving platen and fixed platen of the die-casting machine. The core is to fix the fixed platen by aligning the boss of the die-casting machine barrel with the groove of the fixed die gate sleeve of the mold, and then pre-install the moving platen, correct the mold position with the fixed die, and then lock and install it.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] The installation time of the moving and fixed modules is long: the overhead crane hoisting the moving and fixed templates respectively takes twice as long as the overall mold clamping state (the farther the mold storage area is from the die-casting machine, the longer the hoisting time). The long hoisting time increases the safety risk;

[0005] Low precision: The overhead crane moves and the fixed mold plate moves separately, which cannot ensure the alignment of the movable and fixed molds. Although the movable mold position can be corrected by loosening the movable mold clamp and closing the mold later, due to the initial misalignment, the first mold closing can easily cause mold crushing, which may require secondary adjustment and increase the non-operating time;

[0006] Since the moving and fixed modules need to be loaded onto the machine separately, they are also usually stored separately in the mold repair area. There is a risk of damaging the core and cavity of the temporarily stored mold when lifting mold parts. There is also a risk of foreign objects (such as gloves, mold repair tools) left on the core and cavity. If they are not discovered when loading onto the machine, the first mold closing will not be able to correct the position and will also damage the mold surface. Utility Model Content

[0040] The utility model provides a highly efficient die-casting mold replacement device, comprising a guide rail mechanism 1, a first guide block 2, a second guide block 3, a moving oil cylinder 4 and a side locking structure, wherein a moving module 5 and a fixed module 6 are connected through the side locking structure, the side locking structure can be opened by a key, the guide rail mechanism 1 is slidably connected to a coring column 7 on a die-casting machine, a shell of the moving oil cylinder 4 is connected to a fixed die plate 8 on the die-casting machine, an output shaft of the moving oil cylinder 4 is connected to the guide rail mechanism 1, the first guide block 2 is connected to the top end of the guide rail mechanism 1, the second guide block 3 is connected to the bottom end of the fixed module 6, and the second guide block 3 can be released from the first guide block 2 and cooperated for positioning. The utility model provides an efficient die-casting mold replacement device. When changing the mold and loading the machine, the movable module 5 and the fixed module 6 are connected by a side lock structure, so that the movable module 5 and the fixed module 6 are in a mold-closing state during the loading process. In the process of placing the mold in the mold-closing state toward the guide slide mechanism 1, the first guide block 2 and the second guide block 3 will gradually contact, and rely on the structures of the first guide block 2 and the second guide block 3 to perform positioning and matching, so that the mold in the mold-closing state is fixed at the specified position of the guide slide mechanism 1, and then the moving oil cylinder 4 is started to make the guide slide mechanism The rail mechanism 1 moves toward the fixed mold plate 8 until the barrel boss of the fixed mold plate 8 is aligned with the gate sleeve groove of the fixed module 6, so that the fixed module 6 is installed, and then the movable mold plate is moved toward the movable module 5 until the barrel boss of the movable mold plate is aligned with the gate sleeve groove of the movable module 5, and then the side lock structure is opened, and the movable mold plate moves with the movable module 5 in the direction away from the fixed module 6 to complete the installation.

[0041] As an optional embodiment, the number of the second guide block 3 and the number of the first guide block 2 are both two, in order to make the positioning more accurate. The number of the moving oil cylinder 4 is two, and the two moving oil cylinders 4 are respectively located on both sides of the fixed mold plate 8, in order to guide the movement trajectory of the slide rail mechanism 1 to perform linear reciprocating motion along the coring column 7 parallel to the mold opening and closing direction.

[0042] As an optional implementation, the side end of the first guide block 2 is provided with a protruding strip 21, and the protruding strip 21 is provided with a first inclined surface 211; the side of the second guide block 3 is provided with a second inclined surface 31, and the first inclined surface 211 can contact with the second inclined surface 31 and can move and guide.

When the mold descends to the bottom, it will be positioned by the positioning convex plate 22 and the positioning groove 33, thereby limiting the positioning of the mold in the front and rear directions, and finally realizing the positioning of the mold on the guide rail mechanism 1.

[0045] As an optional implementation, the first guide block 2 is provided with a plurality of first connection holes 23, which are connected to the guide rail mechanism 1 by screws; the second guide block 3 is provided with a plurality of second connection holes 34, which are connected to the fixed module 6 by screws.

[0047] As an optional implementation, a control device is also included, and the control device is used to control the movement of the motion cylinder 4.

[0048] The operating steps of an efficient die-casting mold replacement device of the utility model are as follows:

[0049] Step 1: Move the moving die plate of the die-casting machine back to the maximum distance, and move the mold in the mold-closing state to the top of the die-casting machine table;

[0050] Step 2: The guide rail mechanism 1 is controlled by the control device to make the moving cylinder 4 extend and move forward to the limit position (the limit distance is greater than the distance of the die-casting machine barrel boss);

[0051] Step 3: The crane slowly lowers the mold, aligning the second guide block 3 on the mold with the first guide block 2 on the guide rail mechanism 1. Note that the positioning convex plate 22 and the positioning groove 33 also need to be aligned. After alignment, continue to move downward until the bottom fits together and the crane wire rope is just in a tensioned state;

[0052] Step 4: The guide rail mechanism 1 is controlled by the control device to make the motion cylinder 4 retract and retreat to the origin. At the same time, the overhead crane hanging the mold needs to move horizontally in synchronization with the moving direction and speed of the guide rail mechanism 1. Here, confirm whether the barrel boss of the die-casting machine is smoothly connected with the groove of the mold gate sleeve;

[0053] Step 5: Move the dynamic platen of the die-casting machine forward to the thickness of the mold (without increasing pressure), lock the clamps in all directions of the dynamic and fixed modules, ensure that the mold is fastened to the dynamic and fixed die-casting platens respectively, the overhead crane goes down, takes out the wire rope, and the lifting is completed.

[0054] Step 6: Open the side lock structure, and the die-casting mobile template drives the dynamic module 5 to retreat and open the mold, entering the mold pre-production inspection link, and the mold replacement and machine steps are completed.

[0055] Advantages of the utility model of an efficient die-casting mold replacement device:

[0056] 1. There is no need to hoist the movable and fixed molds separately. The mold can be hoisted onto the machine in the closed mold state, which can efficiently complete the mold change of the integrated mold on the machine, saving half the time compared with the original separate hoisting of the movable and fixed molds on the machine;

[0057] 2. The movable and fixed molds are installed in one piece in the mold-closing state, achieving high precision in mold installation. The mold installation and positioning is free from the conventional barrel centering method. The precision of the bottom guide rail mechanism 1 ensures the centering of the entire mold. At the same time, the relative size relationship of the mold bottom ensures that the mold bottom is in place and the barrel position is also centered.

[0058] 3. The guide rail mechanism 1 is guided and positioned by the coring column 7 of the die-casting machine, ensuring high precision of forward and backward movement. This is the first attempt in the industry.

[0059] 4. The positioning of the mold and the guide rail mechanism 1 is efficiently slid into place through the inclined surface guide, which has the characteristics of simple structure and easy operation. It is also possible to install guide sleeves (2) on the mold and guide posts (2) on the top of the guide rail mechanism 1. As long as the bottom of the mold fixed mold side is positioned with the lower guide rail mechanism 1 and then the mold is installed by front and rear displacement, it is within the protection scope of the utility model.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
