Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a convenient die changing device. Background Art

[0002] With the rapid development of new energy, various materials and batteries emerge in an endless stream, but so far there is no unified standard material battery model to achieve safety and long battery life. For this reason, researchers can only find a suitable solution by testing different alloy materials and matching different sizes for R&D tests, which involves the need to replace molds of different models and sizes. At present, the preparation of material batteries is mainly achieved through metal extruders, which is an important method of forming metal plastic pressure. Its important feature is that it can process metal ingots into materials in a flash.

[0003] Currently, a Chinese patent with authorization announcement number CN202803801U and authorization announcement date of March 20, 2013 discloses a continuous extruder die, which is provided with a plurality of wire output ports.

[0004] The die of this continuous extruder is provided with several wire output ports (also called naan cores), so that multiple metal ingots can be processed simultaneously, thereby improving production efficiency. However, when producing different types of products, the entire die needs to be replaced because of the need to adapt to naan cores of different shapes, which is inconvenient.

[0005] The existing method of replacing the mold of a metal extruder is to fix the mold in a large nut, and then connect the large nut to the extrusion equipment through a thread. The entire process of replacing the mold requires at least three people to complete, and there is a certain degree of risk, which is time-consuming and labor-intensive. Utility Model Content

[0006] In view of the fact that the existing metal forming machine in the prior art has a complicated mold replacement method and requires multiple workers, the purpose of the utility model is to provide a convenient mold replacement device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a convenient mold changing device, comprising: a fixed seat, at least one latch positioning unit installed on the fixed seat, a mold mounting seat is detachably installed in the fixed seat through the latch positioning unit, and a rotating unit is detachably connected between the fixed seat and the bottom of the mold mounting seat, a rotating gap is left between the mold mounting seat and the fixed seat through the rotating unit, so that the mold mounting seat can rotate on the fixed seat, and the mold mounting seat and the latch positioning unit are arranged vertically.

[0008] Furthermore, a storage cavity for accommodating the mold mounting seat is provided in the fixing seat; the latch positioning unit directly passes through the fixing seat and partially extends into the storage cavity to the mold mounting seat.

[0009] Furthermore, rolling elements for driving the mold mounting seat to move into or out of the placement cavity are arranged at intervals on the fixed seat along the path of the placement cavity.

[0010] As a preferred embodiment of the present application, the latch positioning units are provided on the fixing seats on both sides of the mold mounting seat.

[0011] Furthermore, the latch positioning unit comprises: a telescopic member fixed on the side wall of the fixing seat and a locking block driven by the telescopic member to extend into or out of the mold mounting seat; the locking block is provided with an inclined surface that fits the guiding inclined surface in the mold mounting seat.

[0012] Furthermore, a distance adjuster is threadedly sleeved on one end of the telescopic member away from the locking block.

[0013] Furthermore, the rotating unit includes: a rotating shaft rotatably arranged in the storage cavity and two hinges relatively sleeved on the rotating shaft, wherein one hinge is detachably connected to the fixing seat, and the other hinge is detachably connected to the mold mounting seat.

[0014] As a preferred embodiment of the present application, a handle is installed on the mold mounting base.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The present application uses a latch positioning unit to ensure that the mold mounting seat and the fixing seat are effectively fixed to ensure the formability of the workpiece and avoid the mold shaking during the extrusion process, which may cause deformation of the workpiece;

[0017] Secondly, the mold mounting seat rotates the mold out of the fixing seat through the rotating unit provided, so as to facilitate the subsequent switching of different mold models. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figure 1-8 As shown, since the mold currently used is mainly connected to the extrusion equipment through threads, the entire mold replacement process requires at least multiple workers to work together to complete, which is time-consuming and labor-intensive. To this end, the applicant now provides a convenient mold changing device, including: a fixed seat 1, at least one latch positioning unit 2 installed on the fixed seat 1, a mold mounting seat 4 is detachably installed in the fixed seat 1 through the latch positioning unit 2, and a rotating unit 3 can be detachably connected between the fixed seat 1 and the bottom of the mold mounting seat 4 through a latch. Therefore, the present application uses a double detachable fixing structure (i.e., the latch positioning unit 2 and the rotating unit 3) to effectively fix the mold mounting seat 4 in the fixed seat 1 to ensure that the mold remains stable and fixed during die pressing. In actual operation, a rotation gap is left between the mold mounting seat 4 and the fixed seat 1 through the rotating unit 3, so that the mold mounting seat 4 can effectively rotate on the fixed seat 1, and the extension direction of the mold mounting seat 4 when fixed is vertically arranged in the same horizontal plane as the travel direction of the latch positioning unit 2.

[0030] In order to facilitate the effective cooperation with the pin positioning unit 2 to effectively position the mold mounting seat 4, a storage cavity 11 for accommodating the mold mounting seat 4 is opened in the fixed seat 1, and the mold mounting seat 4 can follow the rotation unit 3 to partially shift to the outside of the fixed seat 1; the pin positioning unit 2 directly passes through the fixed seat 1 and partially extends into the storage cavity 11 to the mold mounting seat 4.

[0031] Rolling members 6 for driving the mold mounting seat 4 to move into or out of the storage cavity 11 are arranged at intervals on the fixed seat 1 along the path opened in the storage cavity 11. Specifically, a rolling member 6 is installed on any side fixed on and located above the storage cavity 11. The rolling member 6 is preferably made of a bull's eye ball bearing.

[0032] For the convenience of explanation, taking the drawings in the specification as an example, latch positioning units 2 are provided on the fixing seats 1 on the upper and lower sides of the mold mounting seat 4 .

[0033] The latch positioning unit 2 includes: a telescopic member 22 fixed on the side wall of the fixing seat 1 and a locking block 21 driven by the telescopic member 22 to extend into or withdraw from the mold mounting seat 4; the inclined surface provided on the locking block 21 fits the guiding inclined surface 41 in the mold mounting seat 4. In this embodiment, four latch positioning units 2 are preferably provided, which are arranged opposite to each other in pairs, and the latch positioning units 2 are mainly fixed to the fixing seat 1 by screws and positioning pins. When the mold needs to be replaced, the locking block 21 on the telescopic member 22 (preferably a telescopic rod driven by a hydraulic cylinder) can be withdrawn from the mold mounting seat 4.

[0034] Taking into account the wear and tear of the workpiece during use, in order to ensure that the locking block 21 can always fit within the guiding slope 41 in the mold mounting base 4, a distance adjuster 7 (preferably a nut) is threadedly sleeved on the end of the telescopic member 22 away from the locking block 21. The operation method is to change the distance of the telescopic member 22 controlling the locking block 21 to extend into the mold mounting base 4 by rotating the nut on the telescopic member 22 (specifically a screw).

[0035] The rotating unit 3 includes: a rotating shaft 32 rotatably arranged in the storage cavity 11 and two hinges 31 relatively sleeved on the rotating shaft 32, wherein one hinge 31 is detachably connected to the fixed seat 1, and the other hinge 31 is detachably connected to the mold mounting seat 4. The rotating shaft 32 is installed in the storage cavity 11 of the fixed seat 1 through a latch. In actual operation, in order to prevent the mold mounting seat 4 and the mold from being too heavy, the center of gravity may be unbalanced and cause the rotating shaft 32 to lock. Therefore, a tapered roller bearing is also installed in the storage cavity 11 of the fixed seat 1.

[0036] In order to facilitate manual operation, a handle 5 is installed on the mold mounting seat 4.

[0037] Working principle:

[0038] When the mold needs to be replaced, the four latch positioning units 2 must all be withdrawn from the mold mounting seat 4, and then the handle 5 is pulled to rotate the mold mounting seat 4 and withdraw it from the storage cavity 11 of the fixed seat 1 to replace the mold. After the replacement is completed, the mold mounting seat 4 is rotated back into the storage cavity 11, and it is ensured that the four latch positioning units 2 all enter the mold mounting seat 4 and fit against the guide slope 41 in the mold mounting seat 4 to increase the speed of switching molds (in actual operation, the mold is fixed to the mold mounting seat 4 by bolts). The operation is very convenient, and the connection method of the rotating shaft 32 and the roller bearing makes it easier for the mold mounting seat 4 to move outside the fixed seat 1.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
