Utility Model Content

[0005] In view of this, the utility model provides a mold surface processing device for solving the technical problem that the tool needs to be replaced during processing, and the tool of the above patent is not easy to replace, resulting in low processing efficiency of the device.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a mold surface processing device, which has a tool holder, wherein a lifting cylinder is fixedly installed on the tool holder, and a movable end of the lifting cylinder extends downward and a mounting tool seat for placing a processing tool is fixedly installed on the end;

[0009] A pushing assembly is provided between the rotating shaft and the tool mounting seat, and the pushing assembly comprises a pushing plate for pushing the tool and a vertical cylinder and a horizontal cylinder for driving the pushing plate.

[0010] On the basis of the above technical solution, the mold surface processing device of the utility model can also be improved as follows:

[0011] Furthermore, the vertical cylinder is fixedly mounted on the tool holder, the movable end of the vertical cylinder extends downward and the end portion is fixedly mounted with the transverse cylinder, and the movable end of the transverse cylinder extends rightward and the end portion is fixedly mounted with the push plate.

[0012] Furthermore, the replaceable knife seat has a notch, and a clamping block is symmetrically fixedly installed at the notch, and a clamping tongue with an elastic structure is provided at the front end of the clamping block.

[0013] Furthermore, a plurality of driving grooves and sliding grooves are provided in the circumference of the cutter disc, the number of the driving grooves is equal to the number of the sliding grooves and they are arranged alternately, and the replaceable cutter seats correspond to the sliding grooves one by one.

[0014] Furthermore, a rotating motor is fixedly mounted on the top wall of the tool holder and located on the left side of the rotating shaft, the output shaft of the rotating motor extends downward through the tool holder and is rotatably connected thereto, and a driving shaft is fixedly mounted on the bottom of the output shaft of the rotating motor.

[0036] Optionally, in the above technical solution, the vertical cylinder 41 is fixedly mounted on the tool holder 1, the movable end of the vertical cylinder 41 extends downward and a transverse cylinder 42 is fixedly mounted on the end, and the movable end of the transverse cylinder 42 extends rightward and a push plate 43 is fixedly mounted on the end.

[0037] Optionally, in the above technical solution, the replaceable knife seat 23 has a notch, and a clamping block 24 is symmetrically fixedly installed at the notch, and a clamping tongue 25 with an elastic structure is provided at the front end of the clamping block 24.

[0038] Optionally, in the above technical solution, a plurality of driving grooves 51 and sliding grooves 52 are provided in the circumference of the cutter disc 22 , the number of the driving grooves 51 and the sliding grooves 52 are equal and staggered, and the replacement cutter seat 23 corresponds one to one with the sliding grooves 52 .

[0039] Optionally, in the above technical solution, a rotating motor 5 is fixedly installed on the top wall of the tool holder 1 and located on the left side of the rotating shaft 21, and the output shaft of the rotating motor 5 extends downward through the tool holder 1 and is rotatably connected thereto, and a driving shaft 53 is fixedly installed at the bottom of the output shaft of the rotating motor 5.

[0040] Optionally, in the above technical solution, an arc disk 54 is fixedly installed on the bottom wall of the driving shaft 53, one end of a connecting rod 55 is fixedly installed at the center of the arc disk 54, and a pin shaft 56 slidably connected to the driving groove 51 is fixedly installed on the other end of the connecting rod 55.

[0041] The replacement blade holder 23 and the installation blade holder 31 have the same structure, and the openings of the two are opposite to each other.

[0042] The clamping block 24 is clamped with the cutter, and the end of the clamping tongue 25 is an arc-shaped structure.

[0043] Working principle:

[0044] When in use, the lifting cylinder 3 drives the tool installed in the tool holder 31 to move up and down, and cooperates with the plane movement of the mold workpiece to perform surface treatment on the mold;

[0045] When the tool needs to be replaced: the lifting cylinder 3 drives the tool on the tool holder 31 to move to the highest end (i.e., located on the same plane as the replacement tool holder 23), and then the horizontal cylinder 42 is started to drive the push plate 43 to move to the right side of the tool in the tool holder 31, and the vertical cylinder 41 is started to move the push plate 43 downward to correspond to the tool position;

[0046] At this time, the cutter disc 22 is adjusted so that the replacement cutter seat 23 without a cutter corresponds to the installation cutter seat 31, and the transverse cylinder 42 is started to drive the push plate 43 to move leftward, so as to push the cutter in the installation cutter seat 31 into the replacement cutter seat 23;

[0047] The vertical cylinder 41 is started to drive the push plate 43 to move upward, and the horizontal cylinder 42 is started to drive the push plate 43 to move leftward. After moving to the left side of the replacement tool holder 23, the vertical cylinder 41 is started to drive the push plate 43 to move downward to push the subsequent tool return.

[0048] At this time, adjust the tool disc 22 again, and match the replacement tool holder 23 where the tool to be replaced is located with the installation tool holder 31 which does not have a tool at this time, start the transverse cylinder 42 to drive the push plate 43 to move right, and push the tool in the replacement tool holder 23 into the installation tool holder 31 to complete the tool replacement.

[0049] The adjustment method of replacing the knife holder 23 is as follows: in the initial state, Figure 2As shown, the mounting tool seat 31 is in contact with its corresponding replacement tool seat 23; the rotating motor 5 is started to drive the driving shaft 53 to rotate, and the arc disk 54 and the connecting rod 55 on the driving shaft 53 rotate accordingly. The rotation of the connecting rod 55 drives the pin shaft 56 to rotate, so that an adjacent replacement tool seat 23 moves to the replacement tool seat 23 that originally corresponds to the mounting tool seat 31. At each tool change, there is always a replacement tool seat 23 corresponding to the mounting tool seat 31.

[0050] Among them, the connecting structures such as the driving groove 51, the sliding groove 52, the pin shaft 56, etc. adopt the groove wheel structure principle, which can move each replacement tool holder 23 to a position corresponding to the installation tool holder 31, making tool changing more convenient.

[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
