Description

  The present invention relates to a mounting structure for a molded product take-out device for attaching a molded product take-out device to a molding machine body via at least a pair of spaced mounting mechanisms.

  Conventionally, a molded product take-out device that is attached to the molding machine main body of an injection molding machine and takes out the molded product that is ejected from the mold that has been opened by the ejector, and then carries the removed molded product to a product stocker that is attached to the molding machine main body. (Robot for molding machine) is known from Japanese Patent No. 3203513, for example.

By the way, this kind of molded product take-out device is usually attached to the molding machine main body via a pair of spaced attachment mechanisms. In the case of the molded product take-out device of the above-mentioned Patent No. 3203513, one side of the molded product take-out device is attached to the upper surface of the fixed plate via the first leg portion serving as a coupling member, and the other side of the molded product take-out device. The side is attached to the upper surface of the cylinder support board via a second leg portion serving as a coupling member.
Japanese Patent No. 3203513

  However, the above-described conventional structure for removing a molded product has the following problems to be solved.

  First, since the molded product take-out device is installed between the fixed platen and the cylinder support plate, the influence of the mold clamping device on the molded product take-out device cannot be ignored. That is, since the fixed platen supports the fixed mold and the cylinder support plate supports the hydraulic cylinder for mold clamping, vibration and impact associated with the mold opening / closing operation are repeatedly applied to the molded product take-out device during production operation. At the same time, the gap variation (position variation) between the fixed platen and the cylinder support platen repeatedly occurs due to the high-pressure mold clamping operation and temperature change, leading to a decrease in position accuracy and a decrease in mounting strength in the molded product take-out device.

  Secondly, since the molded product take-out device is bridged between the fixed plate and the cylinder support plate, the influence on the mold clamping device cannot be ignored. In particular, along with the refinement of molded products, the mold opening / closing accuracy of the mold clamping device is regarded as important, but the weight of the molded product removal device is added directly to the mold clamping device as a load, and the molded product removal device The traveling rail extends long from the cylinder support panel to the product stocker installation position, and when the product is discharged, a considerable moment is applied to the mounting part and the mold clamping device, which causes a decrease in mold opening / closing accuracy in the mold clamping device. .

  An object of the present invention is to provide a mounting structure for a molded product take-out device that solves the problems existing in the background art.

  The mounting structure D of the molded product take-out device 1 according to the present invention is an installation for mounting the molded product take-out device 1 to the molding machine main body Mo via at least a pair of spaced mounting mechanisms 2 and 3 in order to solve the above-described problem. In the structure, one side Ss of the molded product take-out device 1 is attached to the stationary platen 4 that supports the fixed mold Cc of the mold C through one attachment mechanism 2, and the other side St of the molded product take-out device 1 is While being attached to the molding machine bed 6 located outside the mold clamping device 5 via another attachment mechanism 3, the one attachment mechanism 2 has a coupling member 11 for fixing the molded product take-out device 1 to the stationary platen 4. The other attachment mechanism 3 includes an engagement mechanism portion 12 that allows relative displacement between the molded product take-out device 1 and the molding machine bed 6.

  Moreover, the mounting structure D of the molded product take-out device 1 according to another embodiment of the present invention is configured so that one side Ss of the molded product take-out device 1 is connected to the mold via the one mounting mechanism 2 in order to solve the above-described problem. It is attached to the stationary platen 4 that supports the fixed mold Cc of C, and the other side St of the molded product take-out device 1 is attached to the molding machine bed 6 located outside the mold clamping device 5 via another attachment mechanism 3. In addition, at least one attachment mechanism 2 includes an interval adjustment mechanism portion 13 that adjusts an interval Lv between the molded product take-out device 1 and the molding machine body Mo.

  Thereby, according to the attachment structure D of the molded article extraction apparatus 1 which concerns on this invention, there exist the following remarkable effects.

  (2) Since the mounting mechanism 3 can support the other side St of the molded product take-out device 1, in particular, the vicinity of the tip of the other side St, the direct load applied to the mold clamping device 5 by the molded product take-out device 1 can be halved. In addition, the moment load on the mold clamping device 5 side when the product is discharged can be greatly reduced, and a high degree of mold opening / closing accuracy can be secured.

  (3) Compared to the case of mounting using the upper end of the cylinder support plate (pressure receiving plate) that constitutes the mold clamping device 5, it can be mounted very easily, reducing labor and man-hours during assembly. Can be planned.

  (4) A connecting member 11 for fixing the molded product take-out device 1 to the stationary platen 4 is provided in one mounting mechanism 2, and the relative displacement between the molded product take-out device 1 and the molding machine bed 6 is set in the other mounting mechanism 3. Since the permissible engaging mechanism portion 12 is provided, even if vibration or impact is applied to the molded product take-out device 1 or the interval Lh between the mounting mechanisms 2 and 3 is fluctuated, it is absorbed by the engaging mechanism portion 12 and molded. The adverse effect on the product take-out device 1 is reduced.

  (5) Since the interval adjusting mechanism 13 for adjusting the interval Lv between the molded product take-out device 1 and the molding machine main body Mo is provided in at least one attachment mechanism 2, molding with respect to the molding machine main body Mo at the time of installation or maintenance. By adjusting the interval (height) Lv of the product take-out device 1, the parallelism and the level of the product take-out device 1 can be set easily and accurately.

The take-out unit 62 includes a sub rail 63 that is parallel to the traveling rail 61, and a product chuck unit 64 and a runner chuck unit 65 are loaded on the sub rail 63. Each chuck unit 64 and 65 can move independently on the subrail 63 by a drive mechanism. Further, the product chuck unit 64 includes a chuck arm 67 that moves up and down by a lifting mechanism 66, and the runner chuck unit 65 includes a chuck arm 70 that moves up and down by a lifting mechanism 69. In this case, a product chuck portion 68 is provided at the lower end of the chuck arm 67, and a runner chuck portion 71 is provided at the lower end of the chuck arm 70. And the molded product taking-out apparatus 1 comprised in this way is attached to the molding machine main body Mo by the attachment structure D which concerns on a present Example.

  Next, an attachment structure D according to the present embodiment for attaching the molded product taking-out apparatus 1 to the molding machine main body Mo will be described with reference to FIGS.

  First, one side Ss of the running rail 61 that is one side of the molded product take-out device 1 is attached to the upper end of the fixed platen 4 that supports the fixed die Cc of the mold C through one attachment mechanism 2. As shown in FIG. 1, the attachment mechanism 2 has a coupling member 11 constituted by a relatively short support column, and fixes the lower end of the coupling member 11 to the upper end of the fixed platen 4 and the upper end side of the coupling member 11. The traveling rail 61 is fixed to the bottom 61d. In this case, the coupling member 11 uses hollow steel or the like having a rectangular cross section, and the outer surface of the coupling member 11 can sufficiently withstand at least a moment load applied in the torsional direction from the traveling rail 61. One or two or more rib portions 11r... Thereby, one side Ss of the molded article extraction apparatus 1 is fixed with sufficient strength with respect to the molding machine main body Mo.

  On the other hand, the other side St of the traveling rail 61 which is the other side of the molded product take-out device 1 is attached to the molding machine bed 6 located outside the mold clamping device 5 via the other attachment mechanism 3. The attachment mechanism 3 uses a relatively long column portion 21. In this case, the support bracket 22 is fixed to the end of the molding machine bed 6, and the lower end of the support column 21 is fixed to the support bracket 22, and the support column 21 is erected vertically. In addition, the support column 21 is formed of hollow steel or the like having a rectangular cross section, and the outer surface of the support column 21 can sufficiently withstand various loads including a moment load applied from the traveling rail 61. One or two or more rib portions 21rd..., 21ru.

  Thereby, the support | pillar part 21 is attached with sufficient intensity | strength with respect to the molding machine main body Mo. In this way, the other side St of the traveling rail 61 that is the other side of the molded product take-out device 1 is attached to the molding machine bed 6 located outside the mold clamping device 5 via the attachment mechanism 3. Cylinder support board) 53 is less susceptible to the influence of vibration and position fluctuations, and it is possible to avoid a decrease in position accuracy and a decrease in mounting strength in molded product take-out device 1. Further, since the mounting mechanism 3 can support the other side St of the molded product take-out device 1, particularly the vicinity of the tip of the other side St, the direct load applied to the mold clamping device 5 by the molded product take-out device 1 can be halved. In addition, the moment load on the mold clamping device 5 when the product is discharged can be greatly reduced, and a high degree of mold opening and closing accuracy can be secured. In addition, it can be mounted much more easily than conventional mounting using the upper end of the cylinder support plate (pressure receiving plate) that constitutes the mold clamping device 5, reducing labor during assembly and working. Man-hours can be reduced.

  On the other hand, an upper end of the support column 21 is provided with an interval adjustment mechanism portion 13 that adjusts an interval (height) Lv between the molded product take-out device 1 and the molding machine body Mo, and the interval adjustment mechanism portion 13 and the travel rail 61. Between the bottom portions 61d, an engagement mechanism portion 12 that allows relative displacement between the molded product take-out device 1 and the molding machine main body Mo is interposed.

First, the interval adjusting mechanism unit 13 includes a rectangular lower support plate 24 fixed to the upper end of the column unit 21. 21 ru... Indicates a rib portion provided between the lower support plate 24 and the column portion 21. Then, four insertion holes are formed in the vicinity of the four corners of the lower support plate 24, and the adjustment bolts 26 are inserted through the insertion holes from the lower side. At this time, fixing nuts 27 and 28 are screwed onto the adjustment bolts 26 located on the upper surface side and the lower surface side of the lower support plate 24, respectively. Further, the tips (upper ends) of the adjustment bolts 26 are fixed to the lower surface of the upper support plate 29. The embodiment shows a case where the ends of the adjustment bolts 26 are screwed into the screw holes provided in the upper support plate 29 and fixed by the fixing bolts 30. 31 denotes a spring member interposed between the fixing nuts 27 and the lower support plate 24.

  Accordingly, the position (height) of the adjustment bolts 26 on the lower support plate 24 can be changed by turning the fixing nuts 27, 28, and so on. Therefore, the interval between the lower support plate 24 and the upper support plate 29, that is, the lower The height of the upper support plate 29 can be arbitrarily changed with respect to the support plate 24. Therefore, by adjusting the interval (height) Lv of the molded product take-out device 1 with respect to the molding machine main body Mo at the time of installation and maintenance, the parallelism and the level of the molded product take-out device 1 can be set easily and accurately. .

  Further, the engagement mechanism portion 12 includes a pair of left and right linear guides 35p and 35q attached to the upper surface of the upper support board 29.

In this case, the slider guides 36p, 36q have channel-shaped slider receiving portions 36pi, 36qi on the upper surface, and rail-shaped sliders 37p, 37q engage with the slider receiving portions 36pi, 36qi. Then, the upper end surfaces of the sliders 37 p and 37 q positioned above the upper ends of the slider guides 36 p and 36 q are fixed to the bottom 61 d of the traveling rail 61. In the embodiment, the support frame 38 is interposed between the upper surfaces of the sliders 37p and 37q and the bottom 61d of the traveling rail 61. In addition, the sliding direction of the sliders 37p and 37q coincides with the longitudinal direction of the traveling rail 61.

  As a result, relative displacement between the molded product take-out device 1 and the molding machine main body Mo is allowed, and vibrations and impacts are applied to the molded product take-out device 1 or the distance Lh between the mounting mechanisms 2 and 3 varies. Is also absorbed by the engaging mechanism portion 12, and the adverse effect on the molded product removing device 1 is reduced.

  1 and 2 show a state where the molded product take-out device 1 is attached to the molding machine body Mo. The entire operation of the molded product take-out device 1 is sequence-controlled by a built-in take-out device controller. That is, after the mold is opened, the product chuck unit 64 and the runner chuck unit 65 move the sub rail 63 and the chuck arms 67 and 70 are moved up and down in the take-out unit 62 at the position indicated by the solid line in FIG. Thereby, the product chuck part 68 chucks the product (molded product) and takes it out from the movable mold Cm, and the runner chuck part 71 chucks the runner part and takes it out from the fixed mold Cc. Thereafter, the take-out unit 62 moves along the traveling rail 61 to the position (discharge position) indicated by the phantom line in FIG. 1, and the chuck arms 67 and 70 are moved up and down to remove the product chucked by the product chuck portion 68. The runner portion that is housed in the product stocker 57 and chucked by the runner chuck portion 71 is housed in the runner container 58.
