Description

Technical Field

[0001] This utility model relates to the technical field of mold closing, and in particular to a mold closing drive device. Background Technology

[0002] In modern industrial manufacturing, mold closing drive devices are key equipment for achieving efficient production, but existing technologies still have significant shortcomings. Traditional mechanical linkage mold closing devices rely on complex gear and linkage structures to achieve mold opening and closing actions. After long-term operation, friction between parts leads to accelerated wear, and frequent malfunctions significantly increase downtime and maintenance costs. At the same time, energy loss occurs in the transmission process, making it difficult to improve mold closing efficiency. While hydraulically driven mold closing devices have greater mold closing force, the slow response speed of the hydraulic system makes it difficult to adapt to the requirements of rapid prototyping processes. Furthermore, aging hydraulic components are prone to oil leakage, which not only wastes resources but may also corrode equipment and pollute the working environment. In addition, most existing devices lack intelligent adjustment functions, making it difficult to accurately control the mold closing force and speed according to mold specifications and production needs, resulting in insufficient mold closing accuracy and a high product defect rate.

[0029] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0030] Reference Figures 1 to 8 This embodiment provides a mold closing drive device, which includes a mold closing part 100, including a first module base 101 and a first mold 102 disposed on one side thereon.

[0031] The drive unit 200 includes a drive assembly 201 and a hinge assembly 202 connected to its output end. The hinge assembly 202 connects the first module base 101 and the first module 102.

[0032] The mold-closing part 100 is half of the overall mold-closing device. The other half can be the same as the mold-closing part 100 or other structures, but it needs to include a necessary second mold corresponding to the first mold 102. The second mold corresponding to the first mold 102 together form an overall mold-closing mold. In this embodiment, the mold-closing part 100 is applied to a blow molding machine for bottle making.

[0033] During use, the drive component 201 is pushed up, and the driving force is transmitted through the hinge component 202, so that the driving force acts on the first mold 102, and the first mold 102 moves towards the second mold.

[0034] Specifically, the first mold 102 includes a docking plate 102a and a first forming mold 102b detachably connected to one side wall thereon. The other side wall of the docking plate 102a is symmetrically and fixedly connected to a mounting plate 102c and a mounting slide 102d. The mounting plate 102c is located between the mounting slides 102d. The hinge assembly 202 is fixedly connected to the mounting plate 102c.

[0035] The first forming template 102b has several sets of bottle cavities arranged in an array for bottle forming. The first forming template 102b is detachably fixed to the side wall of the docking plate 102a by bolts, pins or guide columns and other fixing structures.

[0036] The hinge assembly 202 includes parallel hinge rods 202a, both sets of hinge rods 202a having the same length and outer diameter, preferably being columnar metal rods. Several sets of first hinges 202b are rotatably sleeved at both ends of the hinge rods 202a, with the first hinges 202b on both sides being symmetrically arranged. The other end of the first hinge 202b is rotatably connected to the first protruding hinge block 102c-1 fixed on the mounting plate 102c.

[0037] Furthermore, preferably, in this embodiment, each hinge rod 202a has three sets of first hinges 202b at one end, and six sets of first hinges 202b at both ends, for a total of twelve sets of first hinges 202b on the two hinge rods 202a.

[0038] A rotation gap is formed between two adjacent sets of first hinges 202b, for a total of four sets of rotation gaps. The first protruding hinge block 102c-1 fixed on the mounting plate 102c is provided with four sets, which are inserted into the four sets of rotation gaps and fixed by pins.

[0039] The hinge rods 202a are connected to each other by the second hinge 202c. The two ends of the second hinge 202c are rotatably sleeved on the outside of the parallel hinge rods 202a. The second hinge 202c is located between the first hinges 202b at both ends of the hinge rods 202a.

[0040] Several sets of limiting sleeves 202d are also fixedly sleeved on the outside of the hinge rod 202a. The limiting sleeves 202d abut against the side walls of the first hinge 202b and the second hinge 202c.

[0041] Furthermore, the second hinge 202c is preferably provided in four sets. The two sets of second hinges 202c located at the edge are attached to the outer wall of the first hinge 202b and their lateral displacement is restricted by the limiting sleeve plate 202d to prevent them from shifting during rotation. A rotation gap is also formed between the two sets of second hinges 202c located in the middle, which are also fixed by the limiting sleeve plate 202d.

[0042] A chain seat 101a is detachably connected to the side wall of the first module base 101. A push plate 101b is symmetrically and detachably connected to the side wall of the chain seat 101a away from the first module base 101. Several sets of second outwardly protruding hinge blocks 101b-1 are fixedly connected in an array on the push plate 101b.

[0043] A third hinge 101b-2 is rotatably inserted between adjacent second protruding hinge blocks 101b-1, and the other end of the third hinge 101b-2 is rotatably sleeved on the hinge rod 202a between the first hinges 202b.

[0044] In this embodiment, the second convex hinge block 101b-1 is arranged in the same way as the first hinge 202b, so that the third hinge 101b-2 can be rotatably sleeved on the hinge rod 202a between the first hinges 202b.

[0045] The drive assembly 201 includes a symmetrically arranged base plate 201a and a first mounting post 201b connecting the base plates 201a. Preferably, four sets of the first mounting posts 201b are provided and detachably connected to the four corners of the base plate 201a. A through hole 201a-1 is provided in the top base plate 201a. The through hole 201a-1 can be circular, elliptical or rectangular. In this embodiment, a rectangular hole is preferred.

[0046] A lifting assembly 201a-2 is movably disposed between the base plates 201a. The lifting assembly 201a-2 includes a combined base plate 201a-2a, an upper lifting rod 201a-2b, a lifting plate 201a-2c, and a connector 201a-2d.

[0047] The lifting rod 201a-2b is movably inserted into the base plate 201a at the bottom, and extends out from the bottom of the base plate 201a.

[0048] The lifting rod 201a-2b is threaded into the base plate 201a at the bottom. A pulley 201a-2b1 is fixedly sleeved on the extended end of the lifting rod 201a-2b. The pulley 201a-2b1 is rolledly connected to the output shaft of the drive motor M fixed on the base plate 201a at the bottom through a synchronous belt 201a-2b2.

[0049] During use, the drive motor M starts, driving the pulley 201a-2b1 to rotate via the synchronous belt 201a-2b2. The bottom outer wall of the lifting rod 201a-2b has a lead screw structure, as shown in the reference. Figure 4 The upper lifting rod 201a-2b is obscured by the base plate 201a and is not shown. The upper lifting rod 201a-2b rotates with the pulley 201a-2b1. Due to the threaded structure, the upper lifting rod 201a-2b can move up and down with the forward and reverse rotation of the drive motor M.

[0050] Reference Figure 5The lifting rod 201a-2b can also have the following structure: the lifting rod 201a-2b is slidably inserted into the base plate 201a at the bottom, and the extended end of the lifting rod 201a-2b is fixedly connected to the output shaft of the second drive cylinder N fixedly connected to the base plate 201a at the bottom.

[0051] In this structure, the lifting rod 201a-2b is a smooth-walled columnar metal rod, which is controlled by the second drive cylinder N. After the second drive cylinder N is activated, it can push the lifting rod 201a-2b to move straight up and down.

[0052] The composite substrate 201a-2a includes a top fixing plate 201a-2a1 and a bottom fixing plate 201a-2a2. The top fixing plate 201a-2a1 is fixedly connected to the top base plate 201a via a second mounting post 201a-2a3, and is also fixedly connected to the bottom base plate 201a via a third mounting post 201a-2a4.

[0053] The top of the lifting rod 201a-2b is rotatably inserted into the middle of the combined base plate 201a-2a. The lifting plate 201a-2c can be fitted through the through hole 201a-1. It is fixedly connected to the bottom plate 201a-2a2 through the fourth mounting post 201a-2a5, and the fourth mounting post 201a-2a5 is slidably inserted into the top plate 201a-2a1.

[0054] Furthermore, when the lifting rod 201a-2b moves upward, it lifts the bottom fixing plate 201a-2a2. The bottom fixing plate 201a-2a2 lifts the connector 201a-2d through the fourth mounting post 201a-2a5 and the lifting plate 201a-2c. During the upward movement of the bottom fixing plate 201a-2a2, the top fixing plate 201a-2a1 is fixed in height through the third mounting post 201a-2a4. When the bottom fixing plate 201a-2a2 moves to the highest position, the bottom fixing plate 201a-2a2 abuts against the top fixing plate 201a-2a1, and the top fixing plate 201a-2a1 plays a limiting role in this process.

[0055] The connector 201a-2d includes a head seat 201a-2d1 and a fourth hinge 201a-2d2 rotatably connected within the head seat 201a-2d1. The other end of the fourth hinge 201a-2d2 is rotatably sleeved on the hinge rod 202a between the second hinges 202c.

[0056] Reference Figure 8As the headstock 201a-2d1 moves upward along the lifting plate 201a-2c, it obliquely pushes the fourth hinge 201a-2d2. The fourth hinge 201a-2d2 pushes the hinge rod 202a to move. The first hinge 202b and the third hinge 101b-2, which were originally in a "V" shape, gradually change into a flat "I" shape. The first hinge 202b on the left side will horizontally push the first mold 102 to move, so that it fits with the second mold.

[0057] The entire device is fixedly connected to the workbench or the ground and can be adjusted according to the actual working height. The specific structure of the workbench is not shown, but you can refer to the support platforms on both sides of the production line for details.

[0058] A support frame 102d-1 is fixedly connected to the bottom of the mounting slide 102d at the corresponding position. The support frame 102d-1 is also installed on the workbench. The fixed slider 102d-2 at the bottom of the mounting slide 102d is slidably engaged with the slide rail 102d-1a fixed at the top of the support frame 102d-1. The mounting slide 102d can ensure the stability of the translation of the first mold 102.

[0059] A stabilizing plate 201c is fixedly installed on one side of the drive assembly 201. A support block 201c-1 is hinged to the headstock 201a-2d1. The support block 201c-1 is slidably engaged with the side wall of the stabilizing plate 201c to ensure that the headstock 201a-2d1 can move smoothly along its axis during the upward movement and avoid deviation.

[0060] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
