Description

Technical Field

[0001] The utility model relates to the field of die-casting spraying, in particular to a box-type tooling quick-change mechanism. Background Art

[0002] Die casting is divided into two parts: before and after picking up the parts. Before picking up the parts, the robot drives the spray equipment to spray the mold surface and deep grooves with the release agent, so that a layer of release agent adheres to the mold surface to prevent the aluminum liquid from sticking to the mold, and it also has a certain cooling effect on the mold; the process after picking up the parts is to automate the processing of the die-cast products, including cooling, deburring, marking and other parts.

[0003] With the development of the industry, more and more parts are using integrated die casting, so that a die casting machine can manufacture multiple products. Similarly, different products correspond to different molds and different spray equipment. When manufacturing another product, not only the mold needs to be replaced, but also the spray equipment.

[0004] The spray equipment can be roughly divided into two parts, the upper part is the gas-liquid control component A, and the lower part is the spray component B (see the attached figure). Figure 1 ), the current connection method between the gas-liquid control component and the spray component is: 10 screws penetrate the gas-liquid control component and are directly locked on the top plate of the spray component.

[0005] When replacing a new mold, it is necessary to replace the spray assembly that matches the new mold. When replacing, first remove the screws connecting the flange and the top plate, then remove the screws connecting the top plate and the gas-liquid control assembly, and then remove the screws in the gas-liquid control assembly that are used to connect the spray assembly before replacing the lower part of the spray assembly. Similarly, to replace the new spray assembly, repeat the above steps in reverse. This replacement method not only requires the removal of a large number of screws, but also increases the difficulty of disassembly exponentially based on the on-site working environment, which greatly reduces work efficiency.

[0006] In view of the above situation, designers urgently need to design a tooling mechanism that can achieve rapid replacement to improve work efficiency. Utility Model Content

[0032] The lower component 2 includes a block-shaped bottom plate 2-1, and a row of spaced-apart ferrules 2-3 are respectively arranged on the front and rear sides of the upper end surface of the bottom plate 2-2. The ferrules 2-3 pass through the opening groove 1-2 and the quick-change hole 1-4 from bottom to top.

[0033] Furthermore, the base plate 1 - 1 is provided with two rows of first locking holes 1 - 8 which are fixed to the gas-liquid control components and are distributed at intervals to fix and lock the two.

[0034] Furthermore, the card plate 1-3 is strip-shaped, the driving ends of the two card plates are opposite to each other, the driving connection end of the card plate 1-3 extends deep below the mounting seat, and the driving hole 1-3.2 is a waist-shaped hole.

[0035] Furthermore, the quick-change hole 1-4 on the clamping plate 1-3 is composed of a large-diameter hole, a small-diameter hole and a connecting section therebetween, and the width of the connecting section is the same as the diameter of the small-diameter hole.

[0036] Furthermore, the mounting base 1-4 of the cam driving mechanism is installed above the card plate and fixedly connected to the base plate by screws and pins 1-9. Two spaced side panels are provided on the mounting base 1-4. A cam rotating shaft 1-6 is rotatably installed between the two side panels.

[0039] The action flow of the utility model during working process:

When the handle 1-5 of the cam drive mechanism is in a state of moving perpendicular to its mounting seat 1-4 (action 1), the quick-change hole 1-4 on the clamping plate 1-3 allows the clamping sleeve to pass through, and the upper and lower components are assembled.

[0042] When the handle 1-5 is in a state of being hidden in its mounting seat 1-4 (action 2), the small diameter of the clamping plate will clamp the small diameter of the quick-change mechanism clamping sleeve 2-2 to achieve the purpose of fixed connection.

[0043] When a new spray assembly needs to be replaced, compared to the previous removal of the screws, it is only necessary to turn the handle 1-5 to action 1, and the clamping plate cancels the clamping of the clamping sleeve 2-3, and the old spray assembly can be replaced together with the lower assembly of the quick-change mechanism. In the state of action 1, the new spray assembly together with the lower assembly of the quick-change mechanism can be assembled with the gas-liquid control assembly (together with the upper assembly), and it is only necessary to turn the handle 1-5 to the state of action 2 again, so that the clamping plate 1-3 clamps the clamping sleeve 2-3 to achieve the connection of the spray equipment.

Even if the spray equipment adds a quick-change mechanism, the total weight is much different from the maximum load of the robot, and the operation is not affected.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
