はこの弊害が一層甚しくなる。 This type of support device was developed in an earlier application (Japanese Patent Application 1983-
No. 150041 (Japanese Unexamined Patent Publication No. 56-78957)), the support members each having one relatively narrow support rail are rigidly connected to the mold support, so that the support members on the one hand Even though it has a tendency to be centered with respect to the rolling surface, on the other hand it is so rigidly connected to the mold support that even relatively small dimensional deviations generate stresses in the support system. . In particular, this problem becomes even more serious in the case of a support member having a large support surface.

る。 It is known to use so-called rolling circulation shoes when low friction, precise guidance and high load-bearing capacities are required. The rolling circulation shoe consists of a support, a headpiece screwed to the support, and a number of cylindrical rollers guided in the support,
They are kept at a distance from each other by spacing elements. The spacing element prevents the roller from falling out of the guideway and causes it to change direction (Industrieveerke Schiefler, Catalog
No. 304, INA Roller Bearings, pp. 122-125, D-8522 Herzogenauratsuha, October 1979). However, this device, previously known as a rolling circulation shoe, cannot be applied to the construction of an injection molding machine. A person skilled in the art does not see any incentive from known principles to provide one sliding shoe with each support member. On the other hand, there is a lack of a suitable concept for incorporating the necessary lateral support into the height-displaceable mold support support. For supporting heavy mold supports, sliding shoes are commonly used, which avoid high specific surface pressures by means of large sliding surfaces. However, even in this case, there are major drawbacks such as large frictional resistance and generation of frictional heat.

る。 The object of the present invention is to completely release the supporting rod from its supporting function, while reducing manufacturing costs and reducing friction losses in all weight classes, starting from the above-mentioned known technology. The object of the invention is to provide a support device of the type mentioned at the outset.

ことにより達成される。 According to the present invention, the case lids 19 are provided in the recesses of the support member 17, and the outsides thereof are connected to a pair of inner walls perpendicular to the running surface of the recesses, and the insides thereof are connected to a common case core. 18 respectively to form a roller case R, and within the roller case R, a large number of running rollers 20 are arranged in an endless guide path 21 of the case lid 19, and some rollers 20 are arranged in a lower linear portion of the guide path 21. This is achieved in that the running rollers 20 of the rollers 20 are uniformly loaded from the cassette core 18, and that some of the running rollers 20 are guided in an unloaded state via the roller shaft 20a in the upper straight section.

る。 If a symmetrical support member is held between the machine base and the support bearing of the mold support and is aligned exclusively with respect to the rail, a stress-free support by the support member is obtained.
This also reduces the axial travel of loosely mounted rollers that rotate in opposite directions on their mutually abutting surfaces.

（特開昭48−22148号公報）参照）。 The configuration of the invention achieves the intended purpose of allowing the support bar to serve as a lateral support and to free the support bar from a guiding function. The structure of the lateral support is also simplified. The mold clamping unit simply needs to be installed on the machine base from above. Self-alignment is achieved by the support member, and no fixation between the mold clamping unit and the machine base is required. Lateral support is known per se (see Japanese Patent Application No. 47-73913 (Japanese Unexamined Patent Publication No. 48-22148)).

負荷がかかる。 One end of the horizontal support rod is attached to the mounting plate 1 of the hydraulic drive device.
12 and the other end is supported in a fixed mold support 111, respectively. Mounting plate 11
2 and the mold support 111 are fixed to the machine stand 25. The piston rod 118 of the hydraulically driven cylinder 113 is seated on the mold support 12 and
The rail 2 is connected to the rail 2 via the height-adjustable support member 17.
It is supported on the rolling belt 27 of 6. Each support member 17 has a horizontal leg portion 17a and a vertical leg portion 17b, and has a vertical threaded bolt 15 and a horizontal threaded bolt 1.
6 and can be adjusted in the height and lateral directions with respect to the mold support 12. Vertical screw bolt 15
is the horizontal portion 13a of the support bearing 13 of the mold support 12
It is screwed therein and fixed in the respective adjustment position by means of a nut 16a. The load on the mold support 12 is transferred to the support member 17 via only the vertical threaded bolt 15.
guided by. The horizontal load of the mold support 12 oriented at right angles to the running direction a is caused by the horizontal threaded bolt 16
and is guided to the support member. This horizontal load may originate, by way of example, from a mold support or from an auxiliary device acting laterally on the injection mold.
It may also result from an inaccurate position of the landing gear, ie, out of the precisely horizontal plane. The support element 17 is captured between the adjacent rail 26 and the associated support bearing 13 and is centered exclusively with respect to the rolling surface of the rolling strip 27 of the rail 26 . Therefore, displacement in the height direction and horizontal direction is possible while maintaining sufficient relative movability between the support member 17 and the support bearing 13 without disturbing the alignment with respect to the rolling surface. This mobility is not lost due to the entrainment piece 31 of the associated support bearing 13, which entrains the support part 17 in the running direction a when the mold support 12 is moved.
The entraining piece 31 has an engaging end 31b that tapers into a conical shape.
into the cavity 35 of the support member 17, forming a ball-and-socket type connection. The engaging end 31b terminates at a certain distance from the arcuate bottom surface of the cavity 35. The engagement end 31b is in entraining contact with the side surface of the support member 17 forming the cavity 35 only in the largest diameter part of the engagement section. Each support member 17 and the associated support bearing 13 have a common plane of symmetry bb. The plane of symmetry bb coincides with the diagonal of the rail 26 and mold support 12. The entraining piece 31 in the plane of symmetry b--b is threadedly connected to the branching part of the support bearing 13 which defines the cavity 14 of the support bearing 13. The entrainment piece 31 is Natsu 3 there.
It is fixed by 1a. The support device is optimal when the support member 17 is loaded vertically and horizontally and the load on the support rod 10 is correspondingly removed, so that the support rod 10 is released from both the support function and the guiding function. adjusted to. In this case, the support rod 10 guided in the guide bush 11 is subjected to tensile or compressive loads only in the axial direction. The guide bearings of the support rod 10 are thereby protected, and the mold halves are accurately guided and pressed against each other in the correct positional relationship. This has great significance when manufacturing precision injection molded products of appropriate dimensions. plane parallel to the fixed mold support 111 and the central axis d-d
The adjustment is made by means of a detection device 50 which measures the deflection of the supported support 12 from a coaxial position.
The detection device 50 is located in the alignment hole 4 of the fixed mold support 111.
5 through an adapter 47. A holder 48 supported by a ball bearing is housed in the adapter 47. A conical mounting shaft 50a is seated in the holder 48 and supports a dial gauge 50b. A sliding surface 50c is formed on the front surface of the housing of the dial gauge 50b, and a measuring probe 50 is formed on the sliding surface 50c.
d is displaceably supported. Measuring probe 50d
The swingable measurement probe 50e is attached to the movable support 1
It can be brought into contact for measurement on the inner mantle surface of the centering hole 51 of No. 2 (indicated by broken lines in FIG. 5) or on its mounting surface. In the former case, the concentric position is measured, and in the latter case, the plane parallelism is measured. The mold support is then subjected to an average load of the mold load.

The alignment of the support member 17 only with respect to the rail 26 is advantageous for parallel operation of the rollers 20 rotating in mutually opposite directions. The rollers 20 of each of the leg portions 17a and 17b are attached to a roller case R, and the roller case R has a case core 18 with a square cross section and two case lids 19 integrally disposed on the case core 18. It is formed. The roller 20 is guided in a guide path 21 of the case lid 19 by a shaft 20a. The rollers 20 are supported on the flat lower surface of the case core 18 in the linear guide path portions oriented toward the rails 26 . Each roller case R can be fitted between recess walls extending in the rolling direction a of the legs 17a, 17b of the support member 17. The roller case R is fixed in the support member by threaded bolts 28 passed through the through holes 30 of the case core 18. The inner diameter of the through hole 30 is made larger than the diameter of the threaded bolt 28. The case lid 19 is engaged in the through hole 30 of the case core 18 with an integral annular flange 19b. The case lid 19 is formed from a deep-drawn stamped steel plate. roller 2
The linear guideway portion subjected to the load is set out with a larger distance from the longitudinal edge 19d than the distance from the longitudinal edge 19c to the guideway portion on the rail 26 side (see FIG. 4). It is continuous with the parallel linear guideway section of the guideway 21 via one circular arc section at each end. Therefore case core 1
Roller 2 rolls idle on the top surface of 8 without any load.
0 is located completely inside the roller case R.
Therefore, the support member 17 is placed on the longitudinal edge 19d of the case lid 19 and transmits its load to the roller case R via the longitudinal edge 19d. The shape of the linear portion of the guide path 21 is defined by the rim portion 19d of the case lid 19. The arcuate portion of the guide path 21 is defined by a groove. Both end faces of the roller case R are covered by plates 22 made of synthetic material. Each of the plates 22 abuts a rolling band 27 of the rail 26 by one abutment piece. The conical protrusion 22a of the plate 22 is engaged in the groove of the support member 17 on three sides of the plate 22. Reinforced edge 22b
is in contact with the inner wall surface of the support member 17. The elastic packing 23 surrounding the roller case R is in contact with the rolling band 27 via the contact piece 23a. The outwardly thickened portion of the packing 23 is restrained between the case lid 19 and the adjacent wall portion of the support member 17. Packing 23 is further secured to rounded brackets 22d of each plate 22.
