DETAILED DESCRIPTION OF THE INVENTION The present invention provides an exchange device for exchanging an injection mold held in an operating position on a mold support 1 through a clamping element, and a the injection mold is moved into and out of the working position in the pressurizing chamber on a sliding path perpendicular to the mold clamping direction of the mold clamping unit by the transport table; The present invention relates to a water W mold clamping unit for a synthetic resin injection molding machine, which is guided via at least one sliding path element.

A known mold clamping unit of this type) (May 1982)

According to Supplementary Volumes 4 to 7), a conveying table formed as a roller carriage is guided together with an injection mold to the front of a pressurizing chamber of an injection molding unit 111, and is inserted into the pressurizing chamber by a drive shaft. I am drawn into it. During this retraction, the injection mold slides along a guide member fixed to the - - side mold support. The injection mold is then clamped onto the mold support along a plane. The injection mold, supported and guided only on its sides, reaches its working position in the following manner. That is, in an injection mold, hydraulic clamping is first fixed to one of the two mold supports through an element, and then both mold supports are fixed by the mold closing movement or mold clamping movement of the mold clamping unit. After being fixedly clamped in such a way that it is centered between the mold supports, another clamp is fixed by means of an element to the other mold support. In that case, the necessary mold closing 11-stroke of the mold clamping unit includes the clamping of the other mold support (described in -).
It is assumed that the clamping elements of the injection mold are completely drawn out from the area of the surface. This limits the automation of mold exchange. Separate tightenings acting sequentially in time also act to cause the elements to shift the centering of the mold. It is therefore an object of the invention to further improve a horizontal mold clamping unit of the type mentioned at the beginning of this section, so that mold changes can be carried out more simply, quickly and with fewer operations.

According to the invention, this problem is solved by the configuration shown in the characterizing part of claim 1. With this configuration, mold exchange can be extensively controlled by the computer program of the injection molding machine. The preconditions for pre-temperature adjustment of the injection molding machine 4 in the preparation position of the transport table 1- are also met. Furthermore, the large closing stroke (mold clamping stroke) of the mold clamping unit that was conventionally required after pushing the injection mold into the pressurizing chamber becomes unnecessary. Since the spatial conditions for the drive device to be accessible in the F direction of the sliding path are met, and this drive device can be applied to the injection mold almost in the plane of the sliding path, that is, without a tilting moment, the pressure chamber side is opened.

By towing the injection mold by the chain via the connecting rod, changes to the injection mold contrary to predetermined standards are avoided.

The present invention provides a vertically-actuating only mold clamp having a transport table for horizontally moving an injection mold half selectively provided with an insert as described in DE 24 21 811 A1. Not limited to units. The injection molding half can be pushed in after selectively feeding the conveying table L7 by movable clamping of the mold clamping unit and floating clamping of the plate.

Guide members 23, 24 each having a guide member 24a are arranged. The back plate 21a of the injection mold 21 located in the path bb comes into contact with the guide surface 23a or the guide surface 24a during the sliding movement. Side path N of the transport table 29
The back plate 21a of the second injection mold 21' in the preparation position 1- comes into contact with the guide surface 24a of the other guide member 24 or the guide surface 23a of the guide member 23. When replacing the mold, the mold support 17 associated with the guide surface 23a or 24a
．． The tightening plane of 18 is approximately within a vertical plane. One side path of the transport table 29 is disposed in front of the pressurizing chamber S, and the separation surface of the injection mold is connected to the transport path a perpendicular to the
-a is located approximately at the intersection k of slip path b-b (Fig. 2)
. In this embodiment, the channel in front of the pressurizing chamber S is designated by the symbol X, and the other channel N is optionally designated as a preparatory channel for pre-temperature adjustment of the injection mold. It is located on the right or left side of the side passage in front of the pressurizing chamber S. The injection mold 21 moves along the sliding path b in the pressurizing chamber S.

When the injection mold 21 moves along the sliding paths bb, , t, the injection mold 21 moves between the guide members 23 and 24 on the transport table 29-L and between the fixed mold supports 17 in the pressurizing chamber S. +1 and the guide rib 22d of the guide member 22. The injection mold 21 is then guided between the surfaces of the clamps of the mold carrier 17, 18 with minimal play. These tightening
The first surface forms a guide surface for the injection mold 21 as required. The distance between the clamping surfaces 17 and 11 of the mold supports 17 and 18 and the injection mold 21 is 0-1 mm, respectively.

In this case, the injection mold 21 is also guided by part guide pins 133, 134 of the mold carrier 17, 18 (FIG. 2).
.

The drive fixed to the guide member 22 for moving the mold 21 on the sliding path b-b 1- is provided with an endless chain 55. The driven chainwheel 52a of the chain 55 is driven around a vertical axis of rotation. Injection mold 211±, chain 55 via connecting rod 120 guided linearly in edge path b-b
is pulled into and out of the operating position by the tow-side running zone of the vehicle. The connecting recess 120a of the connecting rod +20 is a bibon]
separated from phase q by a distance corresponding to the spacing of the entraining pins 58 of the chain 55 formed by the pins; The traction side running band of the chain 55 lies directly in the path of movement of the connecting rod 120. The connecting rod +20 can be connected to the injection mold 21 via the connecting port 120C. These connecting holes), 120c are accommodated in the connecting holes of the injection molding mold 21 when the injection molding mold 21 is placed on the conveying table 28. The connecting rod 120 is connected between the guide member 23 or 24 and another guide member 122 on the transport table 29+, and between the guide ribs 22d and 22e of the guide member 22 in the pressurizing chamber S.
You will be guided between Both injection molds 21.21
' are each connected to one connecting rod +20 both when being conveyed along the conveying path a-a, l- and when sliding on the sliding path b-b.

The last four connecting parts of the connecting rod +20 are widened, especially as shown in FIG. 5.6, to form a connecting groove 120b. According to this configuration, even though the entraining pin 58 of the chain 55 still engages with the connecting rod 120, i.e. is present in its connecting groove 120b, the conveying table 29 remains in the sliding path b-b. At the position of the connecting rod 120 in accordance with FIG. 3, it is transported together with the transport table 29 (together with the associated injection mold). The connecting groove 120b is connected to the connecting rod 1 by the connecting pin 58, which is at this point 11=, t.

The limit switch 121 on the other side is operated. The 1ilJ replacement pin +25 can be brought to its starting position via a return spring 126. The limit switch 121 is connected to the electric control section of the mold clamping unit via conductive wires 121b and 121b'.

The body 4 mold 21.21' is conveyed along the conveyance path a-al-
can be restrained while being transported via an indexing bolt 63 mounted vertically movably in the transport table 28. The indexing bolt 63 is engaged by the indexing rod e3a with a connecting quadrant 120a of a connecting rod 120 connected to the associated injection mold. Injection mold 2 to be replaced
Since the connecting rod 120 is restrained when the mold 1' is taken out from the side path N of the transfer table 28, it is the same as when a new injection mold 21' is placed.

1! J! There is no possibility that Keirin 120 will be eccentric. The connecting rod 120 is held in its linear guideway by a guide pin 127, which is supported in the guide element 23 or 24 or in the guide element 122 and is connected to the connecting rod 1.
20, each of which is engaged in one of the guide grooves 120d.

The index bolt 63 located in the path b-b from time to time
(Fig. 2) shows that the conveyance table 29 finishes its conveyance movement.
At this time, the cam 28n (FIG. 16) of the guide frame 31 disengages the guide frame 31. Indexing port i・63 is coil spring 12

The endless chain 55 engages with its middle running band on the connecting rod 120 and thus directly on the sliding surface of the injection mold, ie at the point where frictional forces are to be overcome. This configuration and the injection mold slipping path b-b
Due to the precise guidance therein, the drive device can cooperate with the chain 55 of the machine, which is arranged asymmetrically with respect to the parting plane of the injection mold 21.

The knee 755 is of course arranged perpendicular to its drive shaft. In particular, as shown in FIG. 10.11, the drive sleeve 52, whose top end is formed as a drive chain wheel 52a, is connected to the output shaft 50a of the hydraulic motor 50 via a threaded bolt 124. The chain 55 has a chain guide wheel 57a directed toward the conveyance table 29.
will be guided through. The chain 55 runs in a corresponding recess 22f of the guide member 22 which holds the drive for one day (FIG. 10.11). The drive sleeve 52 is anchored to the guide member 22 via a bearing bush 123. The transfer table 28 is enclosed in a protective housing such that both side passages are selectively in front of the pressurization chamber S.
(FIG. 1), the transport table 28 reciprocates over a distance approximately half the length of the transport table 28.

The operation of the mold clamping unit is as follows. During normal injection operation, the injection mold 21 is in the operating position between the mold supports 17, 18, corresponding to FIG.

The other injection mold 21' is in the preparation position of the side passage N on the transport table 29 which has been moved to the right, in this position the injection mold 21' is prepared, for example, for a mold change. and especially pre-temperatured. After interruption of the injection molding operation, the change of the mold is controlled according to the program as follows: 6, the hydraulic cylinder 27 is released to overcome the self-restriction of the wedge-shaped piston forest of the injection mold 21, and the locking rod 25 is Excluding preload force. Next, the mold clamping unit is run approximately 1m+nl in two directions. Next, slip path b-
Activate the drive device b. As a result, the injection mold 21 still present in the pressurizing chamber S is pulled along the sliding path bb1 by the chain 55 towards the transport table 29. In this case, the backing plate 21a is first guided between the clamping surface of the fixed support 17 and the guide 22d of the guide member 22, and then towards the transport table 280 and the guide member 23,24. On the ul dynamic mold support side, the contact plate 21b of the injection mold 21 moves toward the r bearing pin 132 of the r dynamic mold support rest 8. One part of the backing plate 21b is blocked by the sliding bearing pin 134 (Fig. 2), and the end of the sliding movement is the area of the transfer table 29 x (Fig. 3) the limit switch disposed on the 121. The limit switch 121 is connected to the transfer table 2.
9 is also sent, and when this signal is generated, the injection mold 21 to be replaced moves to the left, and as shown in FIG.
The 'sP position N indicated by the dotted chain line is reached, and this (<
, and can be further removed from the storage area. At the same time, the injection mold 21' (FIG. 2), which was in the preparation position, was placed in front of the pressurizing chamber S with its dividing plane approximately at the intersection K ( (Fig. 2). If the new injection mold has different dimensions from the injection mold to be replaced, the depth of the new injection mold is set by a partial opening or partial closing stroke of the mold clamping unit according to No. 1. The drive direction is then reversed and the injection mold 21' is pulled toward the operating position by the drive position of the sliding movement of the chain 55. Injection mold 2
1' is guided in a manner corresponding to the replaced mold 21. The injection mold 2+', which has reached the operating position in the pressurized chamber S, presses the limit switch 1 in the area Y (Fig. 3).
25, the limit switch 125 sends out an electrical signal to stop the drive and prepare for direction change for the next mold change. At the same time, and therefore at the end of the push-in coupling T, the injection mold 21' is moved through the clamping rod 25 to the mold support 17 by simultaneous actuation of all hydraulic cylinders 27. It is tightened on the tightening surface of IEI. The injection molding operation can then continue. During the injection molding operation, transport table 2 is moved for the next necessary mold change.
At 9-L, bring another mold to the preparation sideway N;
Adjust the pre-temperature if necessary. The next mold exchange is performed under the control of the data on the newly inserted magnetic tape, as in the mold exchange described above, but in this case, the injection mold to be replaced is removed from the pressure chamber The mold 21 is guided to the right together with the transport table 29. In this sense, the direction of operation of the transport table 28 alternates with each mold change. This is because the side path N for preparation and the side path N are mated when the transport table 29.1 is started to be pushed in, so the injection mold is guided along the transfer path b-b I-. The clamping of the stationary support 17 in the section of the pressurized chamber S is such that the surfaces and guide ribs 22d always serve as guiding elements (r, the injection mold being guided with minimum play between the clamping surfaces of the mold support 17, 18;
It means. According to this embodiment, this minimum play is such that the end 25a (FIG. 3) is always
Also during the sliding movement of the abutment plates 21a, 21b are clearly limited by engagement at the rear. The minimum play is therefore at most equal to the magnitude of the working stroke of the tightening insert 25. According to a specific embodiment, the mold support 17.1
The distance between the clamping surface of 8 is the distance between the clamping surface of the mold support 17 or the clamping surface of the mold support 18 and the adjacent clamping surface of the injection mold 21, respectively. Set to a value between 0 and 1 mm. This satisfies the preconditions for forming the in-cylinder sliding path bb in the compartment of the pressurizing chamber S. It is a patch plate 21a of the injection mold 21,
21b supporting thereon (guiding member 22 with guide ribs 22d and plain bearing pin 1 shown in FIG.
32) can be applied to the mold support 17 as a particularly thin sliding path strip.
．． This is because the drive device can be directly fixed to the mold support 18 and housed on the mold support 17 side. This drive can be installed in the compartment of the guide member 22 as a very compact drive chain. The mold support 17 is fitted along the surface with guiding elements (
The mold support 17 is tightened by the surface and the guide rib 2 of the guide member 22.
2d), the precondition for transmitting the forces acting on the injection mold from the chain 55 via the connecting rod present at the injection mold 10 for all interlocking of the injection mold is fulfilled. . As a result, the connecting action of the connecting rod can be applied to the injection mold 21. , 2+' large postcutting is required and 1. This achieves an objective that is important for both manufacturers and users: That is, this subsequent addition I- is limited only to drilling two cylindrical blind holes into which the connecting rods 120c of the connecting rods 120 enter.
