Description

Technical Field

[0001] The present invention relates to a mold clamping device for a pair of molds provided in an injection molding machine, a die-casting apparatus, and the like.

Background Art

[0002] Injection molding machines, die-casting apparatuses, etc. are known which inject a molding material, such as a plasticized resin or molten metal, into a molding cavity between a pair of molds to form a molded product. Such molding machines include a mold clamping device for opening and closing and clamping the molds, and an injection device for injecting the molding material into the cavity between the clamped pair of molds. The mold clamping device includes a base as a member for supporting main components such as a pair of platen plates.

[0003] In order to support and mold a mold that is wider than can be supported by a platen plate of standard width specification, it is necessary to use a wide platen plate having dimensions in the width direction larger than the standard width specification. In this case, the base for placing the wide platen plate also needs to be wider than the standard width specification. However, in this case, a wide base has to be manufactured, leading to a significant cost increase.

[0004] Patent Document 1 proposes downsizing of the base. That is, Patent Document 1 provides an injection molding machine that suppresses the dimension in the vertical direction while ensuring strength and the accommodation space inside thereof.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, Patent Document 1 reduces the vertical dimension and is therefore not effective for the width dimension of the base.

[0007] Therefore, the present invention aims to provide a base that can be expanded in the width direction while ensuring ease of transport, and a clamping device equipped with such a base. [Means for solving the problem]

Modes for Carrying Out the Invention

[0016] Hereinafter, an embodiment of the present invention, including a base and a clamping device equipped with the base, will be described with reference to the attached drawings. In this embodiment, the base 30 can be configured in two ways: a standard width specification and an extended width specification. The first reference segment 40 and the second reference segment 50 are arranged parallel to each other and facing each other in the width direction W of the clamping device 1, and an extended segment 60 is provided to connect the first reference segment 40 and the second reference segment 50. By connecting the first reference segment 40 and the second reference segment 50, the base 30A is configured as the standard width specification. Furthermore, by arranging the extended segment 60 between the first reference segment 40 and the second reference segment 50, and by connecting the first reference segment 40 and the extended segment 60, and by connecting the second reference segment 50 and the extended segment 60, the base 30B, an extended width specification, is configured. The width of the base 30B is extended in the width direction W by the amount of the extended segment 60 compared to the base 30A. The following describes the overall configuration of the clamping device 1, followed by a description of the base 30 (30A, 30B, 30C).

[0017] [Clamping device 1: See Figure 1] The mold clamping device 1 according to this embodiment comprises a base 30, a fixed mold plate 11 fixed to the base 30, and a movable mold plate 12 provided on the base 30 so as to be movable in the front-rear direction relative to the fixed mold plate 11. The mold clamping device 1 also comprises tie bars 15 provided across the fixed mold plate 11 and the movable mold plate 12, a movable mold plate moving means 18 for moving the movable mold plate 12 forward and backward, and split nuts 19 that engage with the tie bars 15 when clamping the mold. In the clamping device 1, for the sake of explanation, the front (F) and rear (R) are defined as shown in Figure 1, etc. This definition is relative. In addition, in the clamping device 1, the longitudinal direction (L), height direction (H), and width direction (W) are defined as shown in Figures 1, 2, etc.

[0018] The fixed platen 11 is provided at the front end F of the base 30, and the movable platen 12 is slidable relative to the base 30 and positioned opposite the fixed platen 11. In the fixed platen 11 and the movable platen 12, the faces that face each other are called the front faces 11A and 12A, and the faces that face the front faces 11A and 12A are called the back faces 11B and 12B.

[0019] A fixed mold 13 is supported on the front surface 11A of the fixed mold platen 11, and a movable mold 14 is supported on the front surface 12A of the movable mold platen 12, and a cavity is formed between the fixed mold 13 and the movable mold 14 through which the plasticizing resin is injected. The fixed panel 11 and the movable panel 12 are connected by multiple tie bars 15, usually four. When viewed from the front, the four tie bars 15 are positioned at the four corners of the fixed panel 11 and the movable panel 12.

[0020] The tie bar 15 has a piston 16 for generating clamping force on the side of the fixed mold plate 11, and a male thread 17 that is formed in the circumferential direction on the side of the movable mold plate 12. Furthermore, the base 30 is provided with, for example, an electrically operated or hydraulically operated movable mold platen moving mechanism 18, which allows the movable mold platen 12 to reciprocate relative to the fixed mold platen 11. Figure 1 shows the mold closed state in which the movable mold platen 12 is moved toward the fixed mold platen 11 by the movable mold platen moving mechanism 18, and the movable mold 14 is in contact with the fixed mold 13.

[0021] The split nuts 19 are positioned on the back side 12B of the movable mold plate 12, corresponding to each of the four tie bars 15. The split nuts 19 have multiple annular grooves 21 on their inner surface that engage with multiple annular grooves 17 of the tie bars 15.

[0022] [Base 30A (standard width specification): See Figures 2 and 3] The base 30 will be described below, starting with base 30A for the standard width specification and then base 30B for the extended width specification. Base 30A comprises two elements, a first reference segment 40 and a second reference segment 50, and its widthwise dimension W is smaller than that of base 30B, which is related to the extended width specification. The examples of the first reference segment 40 and the second reference segment 50 shown below are symmetrical in the widthwise direction W with respect to the connecting boundary line JB, and have the same shape and dimensions.

[0023] [First Criteria Segment 40] The first reference segment 40 comprises a first mounting base 41, three first connecting members 43 extending in the width direction W from one side of the first mounting base 41, and first connecting means 45 provided at the tip of each of the first connecting members 43.

[0024] [First mounting platform 41] The first mounting base 41 includes, for example, webs 41A1 and 41A2 having a rectangular cross-sectional shape, and flat support plates 41B1 and 41B2 fixed to the front and back surfaces of the webs 41A1 and 41A2 in the height direction H. The webs 41A1 and 41A2 may be made of, for example, square steel pipes. For example, both sides of the support plates 41B1 and 41B2 in the width direction W protrude from the ends of the webs 41A1 and 41A2 in the width direction W. The support plate 41B1 directly supports the fixed mold plate 11 and the movable mold plate 12 on its upper surface, and the support plate 41B2 supports the fixed mold plate 11 and the movable mold plate 12 via the support plate 41B1 and the webs 41A1 and 41A2. The first mounting configuration 41 shows an example consisting of two webs 41A1 and 41A2 and two support plates 41B1 and 41B2, but is not limited to this as long as it can support the fixed platen 11 and the movable platen 12. A sliding plate 41C is fixed to the support plate 41B1 in the movement region where the movable platen 12 moves back and forth relative to the fixed platen 11, in order to facilitate the sliding of the movable platen 12. As the material for the sliding plate 41C, a metal material with a lower coefficient of friction than the material for the support plate 41B1, such as copper or copper alloy, can be used, as well as resin materials with a low coefficient of friction such as PPS (polyphenylene sulfide) and PTFE (polytetrafluoroethylene). The same materials are also applied to the sliding plates 51C and 71C described later.

[0025] [First connecting member 43] Each of the three first connecting members 43 is, for example, made of a rectangular steel pipe, and is fixed to the side of the web 41A2 by welding or other means at one end (base end). In other words, the first connecting members 43 are cantilevered to the web 41A2. One of the three first connecting members 43 is positioned in the central part of the longitudinal direction L of the web 41A2, and the other two are provided at both ends of the longitudinal direction L of the web 41A2. A first connecting means 45 is joined to the other end (tip) of each of the three first connecting members 43. Three is just an example, and the first connecting members 43 may be one or more than three.

[0026] [First connection means 45] The first connecting means 45, provided at the tip of each of the three first connecting members 43, are butted against the second connecting means 55 on the second reference segment 50 and are detachably connected to each other. In this embodiment, a flange-type first connecting means 45 is exemplified, but it is not limited to this. Known detachable butt joint methods such as screw-in or adhesive types can be applied to the first connecting means 45. As shown in Figure 3(b), the first connecting means 45 has four fastening bolt holes 45A that penetrate both its front and back surfaces, two positioning holes 45B for inserting positioning pins, and two push bolt holes 45C. In this case, it is preferable that the two positioning holes 45B and the two push bolt holes 45C are provided symmetrically with respect to the center point CP of the surface of the first connecting means 45. All of these are formed for connecting and separating the first connecting means 45 and the second connecting means 55.

[0027] [Second Criteria Segment 50] The second reference segment 50 comprises a second mounting base 51, three second connecting members 53 extending in the width direction W from one side of the second mounting base 51, and second connecting means 55 provided at the tip of each of the second connecting members 53.

[0028] [Second mounting platform 51] The second mounting base 51 includes, for example, webs 51A1 and 51A2 having a rectangular cross-sectional shape, and flat support plates 51B1 and 51B2 fixed to both the front and back surfaces of the webs 51A1 and 51A2 in the height direction H. The webs 51A1 and 51A2 may be made of, for example, square steel pipes. Both sides of the support plates 51B1 and 51B2 in the width direction W protrude from the ends of the webs 51A1 and 51A2 in the width direction W. Support plate 51B1 directly supports the fixed mold plate 11 and the movable mold plate 12, and support plate 51B2 supports the fixed mold plate 11 and the movable mold plate 12 via support plate 51B1 and the webs 51A1 and 51A2. A sliding plate 51C is fixed to the support plate 51B1 in the movement area where the movable mold plate 12 moves forward and backward to facilitate the sliding of the movable mold plate 12.

[0029] [Second connecting member 53] Each of the three second connecting members 53 is, for example, made of a rectangular steel pipe and is fixed to the side of the web 51A2 at one end (base end) by means of welding or other means. In other words, the second connecting member 53 is cantilevered to the web 51A2. One of the three second connecting members 53 is positioned in the central part of the web 51A2 in the longitudinal direction L, and the other two are provided at both ends of the web 51A2 in the longitudinal direction L. A second connecting means 55 is joined to the other end (tip) of each of the three second connecting members 53.

[0030] [Second connection means 55] The second connecting means 55, which are joined to the ends of each of the three second connecting members 53, are butted against the first connecting means 45 on the first reference segment 40 and are detachably connected. In this embodiment, a flange-type second connecting means 55 is exemplified, but it is not limited to this. Known detachable butt joint methods such as screw-in or adhesive types can be applied to the second connecting means 55. The second connecting means 55 has four fastening bolt holes 55A and two positioning holes 55B for inserting positioning pins, similar to the first connecting means 45, but positioned opposite to the four fastening bolt holes 45A and two positioning holes 45B of the first connecting means 45. However, the second connecting means 55 does not have holes formed opposite to the two push bolt holes 45C formed in the first connecting means 45, and the surface is flat. This is because when separating the first connecting means 45 and the second connecting means 55, push bolts are screwed into the push bolt holes 45C provided in the first connecting means 45 and pressed against the flat surface of the second connecting means 55. The thrust of the push bolts removes the positioning pins fitted into both the first connecting means 45 and the second connecting means 55, allowing the first connecting means 45 and the second connecting means 55 to be separated. In this configuration, the two push bolt holes 45C are provided symmetrically with respect to the center point CP of the first connecting means 45, allowing the two push bolts to evenly press against the opposing surfaces of the first connecting means 45 and the second connecting means 55. This ensures that even when the positioning pin is precisely fitted into the positioning hole, the first connecting means 45 and the second connecting means 55 can be separated without tilting relative to each other, preventing the positioning pin from making uneven contact with the positioning hole and becoming stuck due to localized load.

[0031] [Consolidation / separation of the first criterion segment 40 and the second criterion segment 50: See Figures 2 and 3] The base 30A, consisting of a first reference segment 40 and a second reference segment 50, supports the fixed type plate 11 and the movable type plate 12 in a standard width specification in which the first connecting means 45 and the second connecting means 55 are connected to each other and form a single unit. The portion where the first connecting means 45 and the second connecting means 55 are connected to each other is referred to as the connecting portion J1.

[0032] In the standard width base 30A shown in Figure 2, the height dimension H from the lower surface of support plate 41B2 to the upper surface of support plate 41B1 is L1, the height dimension H from the lower surface of support plate 51B2 to the upper surface of support plate 51B1 is L2, and the height dimension H from the lower surface to the upper surface of connecting part J1 is L3. Then, equation (1) or equation (2) is adopted. L1 = L2 > L3 … Equation (1) L1=L2=L3 … Equation (2)

[0033] When formula (1) is adopted, the first connecting member 43 and the second connecting member 53 are cantilevered to the first mounting base 41 and the second mounting base 51, respectively. If the first reference segment 40 and the second reference segment 50 are transported separately and placed on a flat surface during installation, the first connecting means 45 and the second connecting means 55 will fall downward due to their own weight, causing the first reference segment 40 and the second reference segment 50 to tilt. In this state, it becomes difficult to butt the first connecting means 45 and the second connecting means 55 together. Therefore, it is preferable to jack up each of the first connecting member 43 and the second connecting member 53, or each of the first connecting means 45 and the second connecting means 55, using, for example, jack bolts (not shown), to position the first connecting means 45 and the second connecting means 55 parallel to each other and at the same height before connecting them.

[0034] When formula (2) is adopted, the effort required for connecting, such as jacking up, as in formula (1), can be eliminated. Moreover, in addition to supporting the fixed plate 11 and the movable plate 12 at both ends in the width direction W by the first mounting base 41 and the second mounting base 51, they can also be supported in the central part in the width direction W by the connecting part J1. Furthermore, in addition to supporting the fixed plate 11 and the movable plate 12 along the entire length direction L by the first mounting base 41 and the second mounting base 51, they can also be supported at both ends and the central part in the length direction L by the three connecting parts J1.

[0035] Next, by releasing the connection between the first connecting means 45 and the second connecting means 55, the first reference segment 40 and the second reference segment 50 can be separated, as shown in Figure 3. The separation of the first reference segment 40 and the second reference segment 50 is performed when fixed and movable panels 11 and 12 with a larger width W dimension than those previously used are used.

[0036] [Expanded width specifications: See Figure 4] With the first reference segment 40 and the second reference segment 50 separated, an extension segment 60 is positioned and connected between the first connecting means 45 and the second connecting means 55. Three extension segments 60 are provided, corresponding to three combinations of the first connecting means 45 and the second connecting means 55. Each extension segment 60 comprises, for example, a third connecting member 61 made of a rectangular steel pipe, a third A connecting means 63A provided at one end of the third connecting member 61 in the width direction W, and a third B connecting means 63B provided at the other end of the third connecting member 61 in the width direction W. In this embodiment, flange-type third A connecting means 63A and third B connecting means 63B are exemplified, but the invention is not limited thereto. Known separable butt joint methods such as screw-in or adhesive types can be applied to the third A connecting means 63A and third B connecting means 63B. The third A connecting means 63A has four fastening bolt holes and two positioning holes for inserting positioning pins, similar to the second connecting means 55, and the third B connecting means 63B has four fastening bolt holes, two positioning holes for inserting positioning pins, and two push bolt holes, similar to the first connecting means 45.

[0037] Each extension segment 60 is positioned between the three sets of first connecting means 45 and second connecting means 55, with the thirdA connecting means 63A connecting to the first connecting means 45 and the thirdB connecting means 63B connecting to the second connecting means 55. This constitutes the base 30B with an extended width specification. The base 30B with an extended width specification has a width W dimension that is extended by the dimension L4 of the extension segment 60 compared to the base 30A with a standard width specification.

[0038] The dimensions of the third A connecting means 63A and the third B connecting means 63B when viewed from above are the same as the dimensions of the first connecting means 45 and the second connecting means 55 when viewed from above. Therefore, if the dimensions L4A and L4B are the height (H) dimensions of the connecting portion J2 to which the third A connecting means 63A and the first connecting means 45 are connected, and the connecting portion J3 to which the third B connecting means 63B and the second connecting means 55 are connected, then the following equation (3) or equation (4) holds true. L1=L2>L4A=L4B…Formula (3) L1=L2=L4A=L4B…Formula (4)

[0039] In the base 30B with an extended width specification that satisfies equation (4), the fixed plate 11 and the movable plate 12 are stably supported by the first mounting base 41 and the second mounting base 51, which are separated and spaced apart, by connecting parts J2 and J3 which connect and fix the first mounting base 41 and the second mounting base 51 at both ends in the width direction W. Furthermore, in this base 30B, in addition to supporting the fixed plate 11 and the movable plate 12 over the entire length direction L by the first mounting base 41 and the second mounting base 51, they can also be supported at three locations in the length direction L by a total of six connecting parts J2 and J3.

[0040] [Example of an extended segment: See Figure 5] The above describes an extension segment 60 comprising a third connecting member 61 and third A connecting means 63A and third B connecting means 63B, but a base 30C using the extension segment 70 shown in Figure 5 can also be used. It includes a third mounting base 71 having the same dimensions and shape as the first mounting base 41 and the second mounting base 51.

[0041] The extended segment 70 comprises a third mounting base 71, a total of six fourth A connecting members 73A and fourth B connecting members 73B extending in the width direction W from both sides of the third mounting base 71 in the width direction W, and fourth A connecting means 75A and fourth B connecting means 75B provided at the respective ends of the fourth A connecting member 73A and fourth B connecting member 73B. The third mounting base 71 includes, for example, webs 71A1 and 71A2 having a rectangular cross-sectional shape, and flat support plates 71B1 and 71B2 fixed to both the front and back surfaces of the webs 71A1 and 71A2 in the height direction H. For example, the webs 71A and 71A2 and the support plates 71B1 and 71B2 may be the same shape and dimensions as the webs 41A1 and 41A2 and support plates 41B1 and 41B2, and the webs 51A1 and 51A2 and support plates 51B1 and 51B2. The support plate 71B1 may also be provided with a sliding plate similar to the sliding plates 41C and 51C. Furthermore, if a sliding plate 71C is provided on the upper surface of the third mounting base 71 of the extension segment 70 as in the modified example, the fixed mold plate 11 and the movable mold plate 12 can be supported at three locations in the width direction W of the first mounting base 41, the second mounting base 51, and the third mounting base 71. This reduces the sliding surface pressure caused by the movable platen 12, which has a particularly large width W dimension and increased weight, thereby suppressing a decrease in the lifespan of the sliding plate.

[0042] [4th A connecting member 73A, 4th B connecting member 73B] Each of the 4A connecting member 73A and the 4B connecting member 73B is fixed at one end (base end) to the side surface of the webs 71A1 and 71A2 by means of welding or other means, and is cantilevered by the webs 71A1 and 71A2.

[0043] [4th A connecting means 75A, 4th B connecting means 75B] The 4A connecting means 75A and 4B connecting means 75B, which are joined to the respective ends of the six 4A connecting members 73A and 4B connecting members 73B, are detachably connected to the first connecting means 45 in the first reference segment 40 and the second connecting means 55 in the second reference segment 50. In this embodiment, flange-type 4A connecting means 75A and 4B connecting means 75B are exemplified, but the invention is not limited to these. Known detachable butt joint methods such as screw-in or adhesive can be applied to the 4A connecting means 75A and 4B connecting means 75B. The 4A connecting means 75A has four fastening bolt holes and two positioning holes for inserting positioning pins, similar to the 2nd connecting means 55, and the 4B connecting means 75B has four fastening bolt holes, two positioning holes for inserting positioning pins and two push bolt holes, similar to the 1st connecting means 45.

[0044] [Effects of the embodiment] The base 30 (30A, 30B, 30C) produces the following effects. By making the base 30 separable from each other in a divisible form, a standard-width base 30A and extended-width bases 30B and 30C can be constructed. In particular, when using fixed-type panels 11 and movable-type panels 12 with a large width W dimension, extended-width bases 30B and 30C can be easily obtained by interposing the extended segments 60 and 70 between the first connecting member 43 and the second connecting member 53 of the divided first reference segment 40 and second reference segment 50. Conversely, by removing the extended segment 60, it is possible to easily return to the standard-width base 30A at any time. As a result, the base 30 can be used for both standard-width and extended-width specifications, thus minimizing the cost increase of the base 30.

[0045] Furthermore, by using a divisible base 30, the size of the divided first standard segment 40, second standard segment 50, and extension segments 60 and 70 is reduced, making their transportation easier and reducing transportation costs. In other words, the first standard segment 40, second standard segment 50, and extension segment 60 are transported individually during transportation, and then connected at the installation site.

[0046] In addition to the above, it is possible to select or replace the configurations listed in the above embodiments, or to change them to other configurations as appropriate, as long as it does not deviate from the spirit of the present invention. For example, multiple types of extension segments with multiple dimensions L4 can be prepared. This allows for the construction of bases suitable for the width W dimensions of the fixed panel 11 and the movable panel 12, thus avoiding the construction of bases with unnecessarily large width W dimensions.
