The opening and closing mold structure is arranged on a machine table 81 to slidably form a pair of mold bases 82, 83, and a connecting rod mechanism 84 is formed between the outer side surfaces of the mold bases 82, 83 and the machine table 81. 85 is coupled, and each of the link mechanisms 84, 85 is driven by a hydraulic cylinder 86, 87, so that the two mold bases 82, 83 are relatively displaceable. A bottom mold base 88 is further disposed between the two mold bases 82 and 83. The bottom mold base 88 is driven by the other hydraulic cylinder 89 for upper and lower displacement, and the left mold half 91 and the right half of the mold 9 are disposed. The die 92 is coupled to the die holder 82, 83', and the bottom core 93 is coupled to the die holder 88. The opening and closing mold structure can be driven by the three hydraulic cylinders 86, 87, 89 to respectively drive the two mold bases 82, 83 and the bottom mold base 88 to perform the opening and closing operation. The figure shown in Fig. 4 is the state of the mold, and the one shown in Fig. 5 is the state of the mold opening. The opening and closing structure of the fishing is performed by two hydraulic cylinders 86, respectively driving the mold bases 82, 83 for relative displacement, and driving the bottom mold base 88 (4) '86, 87, 89 by the oil private (10) is through Oil pressure millet 6 M326468 Pu Lai start, the time of its operation is prone to delay, and the operating time points of each hydraulic cylinder 86, 87, 89 may be different, which will affect the opening and closing mode of the blow molding machine Efficiency and precision. In particular, the efficiency of the current blowing machine is increasing day by day, and the number of times the mold can be opened and closed every dozen times may even be dozens of times. Once the operation time of the two hydraulic cylinders is delayed or the timing of the operation is inconsistent, it will affect The efficiency of the entire blow molding machine and the yield of the bottle being blown. In order to improve the aforementioned problems, related improvements have been proposed, such as the German patent DE 19807582 "Blow-molding machine for production of plastic containers" patent, the disclosed structure is in a machine A pair of frame bodies are slidably arranged on the table, and each frame body is respectively provided for a half die, and each frame body and the machine table are connected by a toggle group, and the elbow nodes of each toggle group are respectively supported by an actuator. (such as a pneumatic cylinder or a hydraulic cylinder), and the two actuators are driven by a five-link group, and the middle link of the five-link group is combined with a first roller. The first roller is disposed in a first cam slot. In this way, when the first cam groove is displaced up and down, the middle link of the five-link group can be driven to be displaced to the left and right, and the five-link group is pivoted outward or inward to interlock the two actuators. The two toggle sets are driven to relatively displace the two frames. Further, a bottom mold is provided between the two mold halves, the bottom mold is coupled by a second roller, and the second roller is disposed in the other second cam groove. -M326468 When moving, the bottom mold can be moved up and down by f and the two mold halves are displaced, and the second cam groove is moved to the left and right positions. Therefore, the two bodies can be synchronized with the displacement of the bottom mold to perform the action of opening and closing the mold. The aforementioned DE 19807582 is known _

However, the composition of its overall structure is very complicated, which will affect the mobilization of the opening and closing mode. Furthermore, the first cam groove that drives the left and right displacements of the two frames is driven to be displaced up and down; the second cam groove that drives the upper and lower displacement of the bottom mold is driven to be displaced left and right. The first cam groove and the second cam groove are driven by different power sources to be displaced in different directions, which may cause a problem that the bottom mold and the two bodies cannot be synchronized, and therefore there is still a need for further improvement. In the PCT Patent Publication No. W02007028909, the "LINEAR TYPE MOLDING UNIT FOR A CONTAINER MANUFACTURING INSTALLATION" application discloses another mechanism for opening and closing the mold, which is slid in the machine. For the frame body, each frame body is respectively provided for a half mold, and the two frames are synchronously driven by a first roller and a first follower group for left and right relative displacement, and the two half molds are 8 M326468 is provided with a bottom mold, and the bottom mold is driven up and down by a second roller and a second follower group, and a set of clamping mechanism is respectively disposed on the outer sides of the two frames. The mechanism is driven up and down by the third roller and the third follower group, so that when the two frames are in the mold clamping state, the clamping mechanism abuts the two frames to achieve the function of clamping. In this way, since the first roller, the first roller, the second roller and the third roller are coaxially arranged, the effect of the opening and closing mode can be achieved accurately. However, in the aforementioned W02007028909 patent, since the entire structure lacks the toggle group structure as in the DE 19807582 patent, the clamping force cannot be achieved by the toggle group during mold clamping. Therefore, it is necessary to separately provide a set of clamping mechanisms on the outside of the two bodies to achieve the effect of ensuring the clamping effect. However, the overall structure requires three sets of rollers and five sets of follower sets (the first follower set and the third follower set respectively require two sets to simultaneously drive the two frames and the two clamping modes). Institutional actuation) to achieve the desired action, this will make the entire opening and closing mechanism become quite complex, and the components are quite large. This will not only increase the manufacturing and assembly difficulties, but also become very difficult to use in the future. Therefore, how to design an opening and closing mechanism with precise and accurate opening and closing action and simple structure and easy maintenance is a problem to be solved by this creation. 9 M326468 [New content] The main purpose of this is to solve the above problems and provide a two-link group driven by a cam group to drive the two mold bases and the bottom cymbal to operate synchronously. (4) Clamping action Accurate and accurate opening and closing mechanism. This creation is based on the fact that the entire transmission structure consists of only one cam set, two flail sets and two toggle sets, which simplifies the components and is easy to manufacture and maintain. ^ For the purpose of the foregoing, the opening and closing mechanism of the creation is attached to the mouth of the blow molding machine, and the m-seat is slidable in the form of a slideable left and right, and is set on the machine in a state of being able to slide down - the bottom mold a seat, a joint between the mold base and the machine, a financial section, and a link between the 'shai and a toggle joints respectively connected to a first link set, and the bottom mold base and the second link The group is connected, and the first link group and the second link group are respectively driven by the -cam group. Since the first link set and the second link set are respectively driven by the cam set', the first link set is respectively coupled with the two sets of the block joints, so that the two pull seats can be synchronously actuated relative displacement' And the second link set is connected with the bottom mold base, ', and thus the two mold bases and the bottom mold can be synchronously actuated to achieve the precise and accurate effect of the action of opening and closing the mold. Furthermore, the creation of the first link set and the second link set respectively drives the toggle set and the bottom mold base of the two mold bases by the cam group, and the structure of the entire transmission part is significantly simplified compared with the prior art. Many, and fewer components - M326468 makes manufacturing and maintenance easier. The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings.

Each of the die holders 13 and 14 and the machine table 10 are connected by a toggle set 2, and the two toggle sets 2 are respectively frame-connected with a first link set 3, and the die holder 15 is coupled with a The second link set 4 is coupled, and the first link set 3 and the second link set 4 are driven by a cam set 5, respectively. In this embodiment, each of the toggle sets 2 has two sets of first arm 21 and a second arm 22, and the first arm 21 and the second arm 22 of each of the toggle sets 2 The pivoting portion is coupled by a third arm 23 to synchronize the two first arms 21 of the respective toggle sets M326468 2 with the two second arms 22. Further, when the two mold bases 13 and 14 are in the mold clamping state, the first arm 21 and the second arm 22 are tied in the same straight line. The first link body 3 has a first frame body 31. The two ends of the first frame body 31 are respectively pivotally connected to a left link 32 and a right link 33, and the left link 32 and the right link 33 are respectively connected. The other ends are respectively connected to the pivot joints of the first arm 21 and the second arm 22 of the two toggle sets 2. The second link body 4 has a second frame 41. The second frame 41 is pivotally connected to a connecting rod 42. The other end of the connecting rod 42 is pivotally connected to the bottom mold base 15. The cam group 5 has a first cam 51 and a second cam 52 respectively disposed coaxially with the first link group 3, and the first frame 31 respectively extends the first cam 51 and the second cam 52. There is a bracket 311, 312, and each of the brackets 311, 312 is pivotally provided with a roller 313, 314 for abutting against the first cam 51 and a second cam 52. The cam group 5 has a third cam 53 and a fourth cam 54 respectively disposed coaxially with the second link group 4, and the second frame 41 has a corresponding extension of the third cam 53 and the fourth cam 54 respectively. Each of the brackets 411 and 412 is pivotally provided with a roller 413, 414 for abutting against the third cam 53 and the fourth cam 54. In practice, the two mold bases 13 and 14 are respectively provided for the half mold 6 and 62, and the bottom mold base 15 is provided with a bottom mold 63, so that the two mold bases 13, 14 and the bottom mold base 15 are When the displacement is driven, the two mold halves 61, 62 can be separated from or in contact with the bottom mold 63 to achieve the action of opening and closing the mold. Please refer to Fig. 2A to Fig. 2D, which is a schematic diagram of the operation of the cam group 5 with the first link group 3 driving the two mold bases 13, 14 in the present invention. The lines are simplified. The state shown in FIG. 2A is a state of clamping, and at this time, each of the first arm 21 and the second arm 22 are in the same straight line, so that the mold holders 13 and 14 can be surely held. The two mold halves 61, 62 are closely engaged to avoid the problem of the mold being opened due to excessive pressure when the bottle is blown with high pressure gas. When the first cam 51 of the cam group 5 and the second cam 52 are rotated in the clockwise direction in the figure to the position shown in FIG. 2B, the first cam 51 and the second cam 52 are used by two The rollers 313 and 314 drive the first frame body 31 to swing to the right, and respectively push the left link 32 upward; the right link 33 is pulled downward, and the left link 32 and the right link 33 respectively drive the two elbows.

When the first cam 51 and the second cam 52 continue to rotate in the direction of the clockwise direction 13 M326468 in the figure, the two mold bases 13 and 14 are again driven to gradually move inward, and the mold clamping operation is started until the first When a cam 51 and the second cam 52 are rotated to the position in the 2D drawing, the two die holders 13, 14 will completely abut the two mold halves 61, 62, and return to the state of clamping, and each of them The first arm 21 and the second arm 22 are in the same straight line, so that the two mold halves 61, 62 are closely engaged. Referring to Figures 3A to 3C, the cam group 5 of the present invention drives the second link group 4 to drive the two bottom mold bases 15, and the lines of the structural parts are simplified for ease of expression. The state shown in Fig. 3A is the state of clamping, in which case the die holder 15 is at the highest position, the bottom mold 63 is brought into close contact with the two mold halves 61, 62, and the second frame The body 41 and the connecting rod 42 are in the same straight line, so that the bottom mold base 15 can be mated securely, so that the bottom mold 63 and the two mold halves 61, 62 are closely engaged to avoid blowing the bottle with high pressure gas. The problem of opening the mold due to excessive pressure occurs. When the third cam 53 of the cam set 5 and the fourth cam 54 rotate in the clockwise direction in the figure, the second frame 41 is driven to swing to the left, and the base 42 is driven by the link 42. 15 is moved downward, and the stroke of the mold opening is performed, as shown in Fig. 3B, which is the state of mold opening.
