Detailed Description
Four preferred embodiments of the present invention are illustrated in the accompanying drawings.
First, referring to fig. 1, a mold exchanging mechanism 10 of a linear multi-station molding machine according to a first preferred embodiment of the present invention mainly includes a base 20, a plurality of mold stations 30, a first guide 40, a second guide 50, a first moving part 60, a second moving part 70, and an exchanging unit 80.
The base 20 is a long frame having a substantially rectangular shape, and is used as a base for installing the other components of the mold exchanging mechanism 10 of the linear multi-station molding machine.
The mold stations 30 are sequentially fixed on the base 20 along the long axis direction of the base 20, and each mold station is composed of a mold clamping mechanism for applying a mold clamping force to the mold, so that the mold can be locked by the mold clamping mechanism in different mold stations, and the mold is maintained in a tightly closed mold clamping state, thereby performing a molding operation of the polymer material.
Referring to fig. 2, the first guide portion 40 is fixed on the base 20, extends along the long axis direction of the base 20, is located at the rear side of the mold stations 30, and has two first guide rails 41 parallel to and spaced apart from each other.
Referring to fig. 3, the second guide 50 is fixed on the base 20, extends along the long axis of the base 20, is located at the front side of the mold stations 30, and has two second guide rails 51 parallel to and spaced apart from each other.
Referring to fig. 2, the first moving portion 60 is slidably disposed on the first guiding portion 40, and has a plurality of first sliding blocks 61 slidably disposed on the first guiding rails 41, and a plate-shaped first moving seat 62 is fixedly disposed on the first sliding blocks 61, so that the first moving seat 62 can be guided by the first guiding rails 41 to perform reciprocating linear displacement in a first moving direction x parallel to the long axis of the base 20.
Referring to fig. 3, the second moving portion 70 is slidably disposed on the second guiding portion 50, and has a plurality of second sliding blocks 71 slidably disposed on the second guiding rails 51, and a plate-shaped second moving seat 72 is fixedly disposed on the second sliding blocks 71, so that the second moving seat 72 can be guided by the second guiding rails 51 to perform reciprocating linear displacement in the first moving direction x;
the power for moving the first moving portion 60 and the second moving portion 70 along the first moving direction x can drive the first moving portion 60 and the second moving portion 70 to perform a linear reciprocating motion along the first moving direction x by the rotational motion output by the motor through the engagement between the gears 63 and 73 and the racks 64 and 74, but the driving techniques are disclosed in the prior art, and therefore, the details thereof are not repeated in this embodiment.
Referring to fig. 4 and 5, the exchanging unit 80 has two long straight bar-shaped guide bars 81, which are disposed on the first moving seat 62 in parallel to each other and have a long axis perpendicular to the first moving direction x, a power portion 82, such as a fluid pressure cylinder, which is fixedly disposed on a rear end side of the first moving seat 62 and has a force output shaft extending forward above the first moving seat 62, a coupling seat 83 disposed on a force output shaft end of the power portion 82 and slidably disposed on the guide bars 81 through a slider 831, so that the two movable plate-shaped carrying portions 84, which are respectively used for carrying molds and are respectively disposed on the first moving seat 62 or the second moving seat 72 and can be displaced in the first moving direction x along with the first moving portion 60 or the second moving portion 70, are guided by the guide bars 81 and guided by the force output shaft of the power portion 82, and each of the carrying portions 84 can also passively move in the second moving direction y via the coupling seat 83, so that the mold carried by each of the carrying portions 84 can move in two-dimensional directions in the first moving direction x and the second moving direction y;
in order to allow the power portion 82 to simultaneously drive each carrying portion 84 and the dies carried thereon by a single power source, the exchanging unit 80 further includes a plurality of pairs of connecting portions 85 capable of being coupled to and separated from each other, and the pairs of connecting portions 85 are disposed between the carrying portions 84, specifically, the pairs of connecting portions 85 are configured as a card slot 851 and a card bar 852 that are complementary in shape and capable of being engaged with each other;
furthermore, in order to make the carrying portions 84 move smoothly in the second moving direction y, rolling elements 86 such as bearings may be disposed on the moving path of the carrying portions 84 in the second moving direction y, included in the first moving base 62, the second moving base 72 and each of the mold stations 30 (not shown), so that the rolling elements 86 may roll on the bottom end surfaces of the carrying portions 84 to make the movement thereof in the second moving direction y smooth;
the engagement between the engaging seat 83 and the mount 84 is engaged with the engaging hole 841 of the mount 84 through the engaging pin 832.
By the above components, the mold exchanging mechanism 10 of the linear multi-station molding machine can be selected from any one of the mold stations 30 as a stop mold station 30 'by the linear reciprocating motion of the first moving part 60 and the second moving part 70 along the first moving direction x as shown in fig. 6, so that the first moving part 60 and the second moving part 70 are stopped at the front and rear sides of the stop mold station 30', and then the loading parts 84 are driven by the power part 82 to displace along the second moving direction y as shown in fig. 7 to 10, so that the loading parts 84 can synchronously move forward to the stop mold station 30 'and the second moving part 70 from the originally located first moving part 60 and the stop mold station 30' supported by the rolling elements 86, or vice versa:
as shown in fig. 7, when the first moving portion 60 and the second moving portion 70 stop at the beginning of the mold station 30 ', one of the two carrying portions 84 is used for carrying a mold and is located on the first moving portion 60, and the other one is located in the mold station 30' for performing a predetermined processing operation on the carried mold in the mold station 30 ', and in fig. 7, the state of the first moving portion 60 moving toward the mold station 30' is shown, and after moving to the mold station 30 ', the mold station 30' is used for performing a predetermined processing operation, and the specific operation content is that after the polymer molding process is completed, the mold clamping force applied to the mold is released by the mold clamping mechanism, and the mold is lowered from the mold clamping position at the high position to the mold releasing position at the low position.
Referring to fig. 8, after the mold holding station 30 ' completes the predetermined operation of the molding process, and the mold and the carrying portion 84 in the mold station are moved downward to the releasing position by the mold clamping mechanism, the mold and the carrying portion 84 are moved to the first moving portion 60 of the mold holding station 30 ' along the first moving direction x, so that the carrying portion 84 and the connecting portion 85 of the carrying portion 83 in the mold holding station 30 ' are slidably connected and engaged with each other on the same horizontal plane, and abut against the corresponding rolling element 86 at the bottom side.
As shown in fig. 9, the power provided by the power portion 82 drives the carrying portions 84 to move toward the front side (i.e. the left side direction of the drawing) of the stop mold station 30 ', so that the molds that have completed the molding process can move forward from the stop mold station 30 ' to the second moving portion 70, while the carrying portions 84 and the molds carried by the carrying portions, which are originally located on the first moving portion 60, move forward to the stop mold station 30 '.
Thereafter, as shown in fig. 10, the mold clamping mechanism in the mold station 30 'moves upward from the mold opening position to the mold closing position for the next molding cycle, and during this movement, the carrier 84 on the mold station 30' is separated from the engaging seat 83 and the carrier 84 on the second moving portion 70 as shown in fig. 10.
Then, the second moving portion 70 can drive the carried carrying portion 84 to move along the first moving direction x, but before moving, the mold that has completed the molding process can be opened through an opening portion 90 fixed on the mold station 30', so that the operator can take the molded product out of the mold and properly clean the mold, after that, the second moving portion 70 can move the emptied mold along the first moving direction x, and then the mold is stopped at the front side of a material injection mold station 30 ", and then the carrying portion and the carried mold on the second moving portion 70 are pulled into the material injection mold station 30" by the power portion 82, and the mold and the carrying portion 84 that have completed the material injection in the material injection mold station 30 "are pulled to the first moving portion 60 backward according to the opposite moving step of the above-mentioned forward pushing, then, the first moving part 60 transfers the mold and carrier part with completed injection to another mold station along the first moving direction x, and the process is repeated, so as to achieve faster and more convenient mold exchange than the prior art, thereby effectively increasing the manufacturing efficiency.
In the polymer molding process technology field, the position for injecting or opening the mold is specific, and the number of the mold can be changed according to the requirement of the actual process condition, so that injecting material at a single fixed position and opening the mold at each mold station as disclosed in the first preferred embodiment is only one of the various modes that the present invention can be implemented, but not limited to, and those skilled in the art can combine the technical features disclosed in the present invention with the known technology, for example, in the mold opening operation, in addition to providing mold opening portions at each mold station, only a single mold opening portion can be provided, and the single mold opening portion can move along with each moving portion or be fixed at a fixed position, wherein the former is the second preferred embodiment of the present invention, the latter is the third preferred embodiment of the present invention.
Referring to fig. 11, the mold exchanging mechanism 10a of the linear multi-station molding machine disclosed in the second preferred embodiment of the present invention is identical to the main technical features of the first preferred embodiment, and is different therefrom only in that the structure of the mold exchanging mechanism 10a of the linear multi-station molding machine in the present embodiment can be simplified, so that the mold opening portions provided in each mold station in the first preferred embodiment are only single in the present embodiment, thereby reducing the cost and maintenance burden resulting from the provision of a plurality of mold opening portions in the first preferred embodiment.
Specifically, referring to fig. 12 and 13, in order to make the number of the mold opening parts 90a single, the mold opening parts 90a can move along the first moving direction x with the second moving part 70a, so in this embodiment, the second moving part 70a further includes a frame-shaped connecting member 73a, which is disposed between the second moving seat 72a and the first moving seat 62a to allow the mold opening parts 90a to be disposed, and simultaneously, the first moving seat 62a and the second moving seat 72a can move in the first moving direction x synchronously.
Referring to fig. 14 and 15, in a mold exchanging mechanism 10b of a straight line multi-station type molding machine according to a third preferred embodiment of the present invention, the main technical features of the present invention are the same as those of the first preferred embodiment, except that the present embodiment has only a single mold opening part 90b, and the single mold opening section 90b is fixed to a mold station address such as the injection mold station 30 b', whereby the mold to be opened is removed at each mold station 30b, the second moving part 70b can move the mold to the position of the mold opening part 90b to perform the mold opening process, thus, the worker can carry out the work at a fixed position without walking between different mold stations as disclosed in the first preferred embodiment, thereby reducing the physical burden of the worker and the danger of worker's safety.
Meanwhile, the third preferred embodiment can make the worker work at a fixed point, i.e. as shown in fig. 16, a safety fence 91b is disposed around the whole machine to provide better safety protection.
However, the specific technical content of the mold opening parts 90, 90a and 90b in the embodiments is not necessary in the present specification since the mold opening and closing technology is already disclosed and is known to those skilled in the art of the present invention, and thus the mold opening technology itself is not a technical feature of the present invention.
In addition, in order to effectively utilize the space of the factory building and make the number of the molds installed in a single mold station be a majority, for example, the single mold station is divided into two layers and the molds are respectively accommodated in the spaces of each layer, which belongs to the technical content disclosed in the prior art, therefore, in the fourth preferred embodiment of the present invention, it is disclosed that each mold station is provided with an upper layer space and a lower layer space for accommodating different molds, for this reason, please refer to fig. 17, the mold exchanging mechanism 10c of the linear multi-station type molding processing machine provided in this embodiment is similar in structure to that disclosed in the third preferred embodiment, except that in this embodiment, the injection mold station 30c ″ still maintains a single layer, each mold station 30c for molding processing has a double layer space for accommodating two molds at the same time, and the first moving part 60c and the second moving part 70c can move along the first moving direction x, the first moving direction x is perpendicular to the first moving direction x, and the second moving direction y is perpendicular to the second moving direction y.
In order to make the first moving portion 60c and the second moving portion 70c move along the third moving direction, as shown in fig. 18 to 20, 21 and 22, respectively, the first moving portion 60c and the second moving portion 70c have the same structure, so that the first seat portion 62c and the second seat portion 72c thereof respectively further include a lower plate 621c, 721c, two pairs of guide bars 622c, 722c are respectively erected on both sides of the lower plate 621c, 721c in parallel, a top plate 623c, 723c is fixed on the top end of each guide bar 622c, 722c to stabilize each guide bar 622c, 722c, an upper plate 624c, 724c overlapped above the lower plate 621c, 721c is slidably disposed on each guide bar 622c, 722c, and can move up and down along the axis of each guide bar 622c, 722c in the third moving direction z, two rectangular bar-shaped guide blocks 625c, 725c are respectively slidably disposed on the guide rods 622c, 722c, two rectangular bar-shaped support blocks 626c, 726c are respectively fixed on the middle section of the guide rods 622c, 722c and between the upper plate 624c, 724c and the guide blocks 625c, 725c, two pairs of support rods 627c, 727c are respectively bridged on the upper plate 624c, 724c and the guide blocks 625c, 725c and slidably connected with the support blocks 626c, 726c, two driveable screws 628c, 728c are respectively pivoted with the support blocks 626c, 726c and the lower plate 621c, 721c by two ends, two screw sleeves 629c, 729c are respectively threaded on the screws 628c, 728c and are fixed on the upper plate 624c, 724 c. With the structure provided in the above embodiment, the first moving portion 62c and the second moving portion 72c can further move the upper plates 624c, 724c up and down along the third moving direction z, respectively, as shown in fig. 23 and 24, when they are raised to the position, the upper plates 625c, 725c can be made to correspond to the space in the upper layer of the station 30 ', and the mold can be pushed into the upper space of the station 30' or pulled out from the upper space of the station 30 ', and when they are lowered to the position, the mold can be moved into or out of the lower space of the station 30'.
The lifting displacement of the upper plates 624c, 724c is caused by the screws 628c, 728c to rotate under external force, so that the screw sleeves 629c, 729c screwed therewith can move along the third moving direction z, and simultaneously drive the upper plates 624c, 724c fixedly connected with the screw sleeves 629c, 729c to lift and displace along with the movement, thereby driving the screws 628c, 728c to rotate.
In addition, it should be noted that, in the first to third embodiments, the exchange unit is made to move the two carrying parts simultaneously by the structure of the single power part and the technology of the connection part, but in this embodiment, the exchange unit 80c is made to have no structure of the connection part, and the number of the power parts 82c and the connection seats 83c is further increased to two, and the power parts 82c and the connection seats 83c driven by the power parts are respectively arranged on the upper plate 624c of the first moving seat and the upper plate 724c of the second moving seat, so that the exchange unit 80c can move the mold inside and outside the mold station on the first moving part 60c and the second moving part 70c, respectively, rather than being linked by the connection part to form linkage as in the other embodiments.
The construction of the power portions 82c is also achieved by changing the rotational motion to the linear motion between the screw and the nut in the conventional art of the present embodiment, and the effect of the linear reciprocating motion of the coupling seats 83c is achieved by the screw and nut, and the specific technical contents thereof are the same as those of the screws 628c and 728c and the nuts 629c and 729c, but the transmission structure for driving the screw to rotate is not completely disclosed in the drawings, but the present invention does not cause the situation that the present invention cannot be implemented by those skilled in the art.
