Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a mold release agent spray device that enters from above between the open molds of a die-casting machine and sprays the mold release agent toward the mold surface. be.

[Conventional technology]

The above-mentioned mold release agent spray device is installed on the fixed die plate of the die-casting machine so as to protrude above the mold, so it gets in the way when replacing the mold by lifting it with a chain block or the like. In addition, if the movable mold is equipped with an upwardly protruding cylinder for pulling out the core called a core plastic, there is a problem that this core plastic collides with the spray device part waiting above when the mold closes. . For this reason, in the past, the main body of the spray device was mounted so that it could be horizontally rotated or moved laterally, and when the main body of the spray device became an obstacle (such as when replacing a mold), the main body of the spray device could be moved out from above the mold to the side. It is configured so that it can be done.

[Problem that the invention attempts to solve]

However, the conventional spray device has a problem in that the mounting mechanism for horizontally rotating or laterally moving the device body is very complicated and large-scale.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, this invention has a main body mounting mechanism that supports the main body of the spray device on the fixed die plate of the die casting machine so as to protrude above the mold. a bracket attached to an end position that is displaced in the direction; and a device main body mounting base whose lower end is pivotally supported on a first support shaft and a second support shaft which are spaced apart in the left-right direction of the bracket, and whose upper end is parallel to the bracket. It is composed of a parallel link member pivotally supported on a first support shaft and a second support shaft spaced apart in the left-right direction, and a link operating cylinder pivotally connected to a diagonal shaft support of the parallel link member, The apparatus is characterized in that the main body of the apparatus can be moved from a position above the mold to a position where it escapes to the side by rotating the parallel link member.

〔Example〕

Hereinafter, an embodiment of this devised device will be explained with reference to the drawings. In the drawing, 1 is between the open molds of the die-casting machine (fixed mold A attached to fixed die plate D, movable mold B attached to movable die plate C). 10 is a main body of a mold release agent spraying device that enters from above into the mold surface (between the molds A and B) and sprays the mold release agent e toward the mold surfaces a and b. The main body mounting mechanism 10 is supported on the fixed die plate D of the die casting machine so as to project out as shown in the figure. The bracket 11 is mounted as shown in FIG.
Parallel link members 12 and 13 are pivotally supported on a first support shaft 9a and a second support shaft 9b that are spaced apart in the left-right direction of the device main body mounting base 9, and this parallel link member 1
The link operating cylinder 14 is pivotally connected to two and thirteen diagonal shaft supports.

The link actuation cylinder 14 is, for example, an air cylinder, and is connected to the first support shaft 11a of the bracket 11.
and the second support shaft 9b of the main body mounting base 9, and the lower end mounting portion of the cylinder is pinned to the boss protrusion 12a of one link member 12 as shown in FIG. 2, and the piston rod 14a is The upper end portion of the main body mount 9 is pivotably attached to the second support shaft 9b of the main body mount 9, thereby being pivotally connected diagonally to the link members 11 and 12. The link actuating cylinder 14 is in a contracted block state in which the piston rod 14a is retracted to the maximum extent, and the parallel link members 12, 1
3 to the horizontal top surface of the fixed die plate D at 60
It functions to hold the apparatus main body 1 in the state shown in FIGS. 1 and 3 where it is tilted at an angle of about 100 degrees (a link state in which the device main body 1 is supported so as to project above the molds A and B), but this state When the cylinder 14 is operated to extend a certain stroke, this cylinder operation causes the parallel link members 12 and 13 to move toward the bracket 1.
The apparatus main body 1 is rotated about the first and second support shafts 11a and 11b of the mold as fulcrums as shown by the imaginary line in FIG. It can be moved as shown by the line.
The rotation range of the link members 12 and 13 due to cylinder operation varies depending on the extension stroke of the cylinder 14, but in this embodiment, the extension stroke of the cylinder 14 is set so that the link rotation range is about 60 degrees. It is set.

The apparatus main body 1 includes a cylinder mount 7 supported by two horizontal shafts 8a and 8b on a main body mount 9, a vertically movable cylinder 6 vertically fixed on the mount 7, and a vertically movable cylinder 6. 2 which is attached to the lower end of the piston rod and passes through the cylinder mounting base 6.
There is a spray header 4 which is guided by vertical guide rods 5a and 5b and moves up and down by cylinder operation, and a second spray header between the molds A and B that is attached to this spray header 4 and is opened by the downward movement of the vertical movement cylinder 6. It consists of a plurality of thin tube spray nozzles 3 that enter as shown by the imaginary lines in the figure and spray the mold release agent e onto the mold surfaces a and b. In the case of this embodiment, the lifting guide rods 5a and 5b of the spray header 4 are formed of pipes having passage holes for supplying the mold release agent and spray air to the header 4, and the mold release agent is provided at the upper end of the pipe. Supply hose and air supply hose (not shown)
are now connected. Further, the horizontal shafts 8a and 8b are fitted into the main body mounting base 9 so as to be movable back and forth, and the handle 2a of the screw shaft 2 screwed into the main body mounting base 9 (this screw handle is rotatably connected to the shaft connecting plate 8). The movement in the front and back direction can be adjusted by the screw feeding action by operating the (held). With this configuration, adjustment of the longitudinal adjustment of the apparatus main body 1 can be easily performed when replacing the mold.

[Effect of idea]

The mold release agent spraying device of this invention is as described above, and the device main body 1 is projected onto the fixed die plate D of the die casting machine at a position above the mold.
The main body mounting mechanism 10 supported above is mounted on a bracket 11 at an end position displaced laterally from the center on the fixed die plate D, and a first support shaft 11a and a second support shaft 11a and a second support shaft are spaced apart from each other in the left-right direction of the bracket 11. A parallel link member 12 having a lower end pivotally supported on a supporting shaft 11b and an upper end pivotally supported on a first supporting shaft 9a and a second supporting shaft 9b spaced apart in the left-right direction of the apparatus main body mounting base 9 parallel to the bracket 11. , 13, and a link operating cylinder 14 pivotally connected to the diagonal shaft supports of the parallel link members 12, 13, the main body mounting mechanism 10 is capable of horizontally turning or transversely moving the main body of the apparatus, unlike the conventional main body. Although it is a simple main body mounting mechanism, when the device main body 1 gets in the way (such as when replacing a mold), the link actuation cylinder 14 can be operated to remove the device main body. 1 can be reliably moved from a position above the mold to a position where it escapes to the side.
