Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an automatic mold adjustment device for injection molding machines. Background Technology

[0002] In the production process of plastic products, injection molding machines are indispensable key equipment. As the core component of injection molding, the installation and adjustment accuracy of molds directly affects the dimensional accuracy, appearance quality and production efficiency of plastic products. Therefore, mold adjustment devices are often used when installing and adjusting molds.

[0003] Based on the above, the inventors have discovered the following problem: When using the current automatic mold adjustment device for injection molding machines, it can often only adjust the height of the mold, and its lateral alignment adjustment is inconvenient, thus affecting the alignment efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic mold adjustment device for injection molding machines, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic mold adjustment device for injection molding machines, so as to solve the problem mentioned in the background art that the current automatic mold adjustment devices for injection molding machines can only adjust the height of the mold, and the horizontal alignment adjustment is inconvenient, thus affecting the alignment efficiency.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An automatic mold adjustment device for an injection molding machine includes a base plate, a lifting plate at the top of the base plate, a height adjustment mechanism at the top of the base plate for adjusting the height of the lifting plate, a movable plate at the top of the lifting plate, and a translation mechanism at the top of the lifting plate for adjusting the position of the movable plate. The translation mechanism includes a one-way threaded rod, with first retainers fitted at both ends of the one-way threaded rod. The bottom end of the first retainer is fixedly connected to the top of the lifting plate. A movable block is fitted on the outer side of the one-way threaded rod, with the top end of the movable block fixedly connected to the bottom end of the movable plate. A first motor is installed on one side of one of the first retainers, and the output end of the first motor is connected to one end of the one-way threaded rod. A pair of first sliding rods are slidably connected to the inner side of the movable block, with both ends of the first sliding rods fixedly connected to the inner sides of the pair of first retainers. Brackets are provided on both sides of the top of the movable plate, and a distance adjustment mechanism is provided at the top of the movable plate for adjusting the distance between the pair of brackets. Support seats are installed at the four corners of the bottom of the base plate.

[0008] Furthermore, the height adjustment mechanism includes a first bidirectional threaded rod, both ends of which are rotatably connected to a second retainer. The bottom end of the second retainer is fixedly connected to the top end of the base plate. Both ends of the first bidirectional threaded rod are fitted with a first slider. The top end of the first slider is equipped with a first hinge. One end of the first hinge is equipped with a diagonal brace. One end of the diagonal brace is equipped with a second hinge. One end of the second hinge is equipped with a height-increasing block. The top end of the height-increasing block is fixedly connected to the bottom end of the lifting plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since both ends of the first bidirectional threaded rod are fitted with first sliders, the rotation of the first bidirectional threaded rod can drive the first sliders to move, and the height of the lifting plate can be adjusted by connecting the diagonal brace to the heightening block through a hinge.

[0010] Furthermore, a second motor is mounted on one side of one of the second cages, and the output end of the second motor is connected to one end of the first bidirectional threaded rod.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by connecting the output end of the second motor to one end of the first bidirectional threaded rod, the first bidirectional threaded rod can be electrically rotated, thereby precisely adjusting the height of the lifting plate.

[0012] Furthermore, a pair of second slide rods are slidably connected to the inner side of the first slider, and the two ends of the second slide rods are respectively fixedly connected to the inner side of a pair of second retainers.

[0013] The beneficial effect of adopting the above-mentioned further solution is that a pair of second slide rods are slidably connected to the inner side of the first slider, which prevents the first slider from shaking or deviating under the drive of the threaded rod.

[0014] Furthermore, the adjusting mechanism includes a second bidirectional threaded rod, both ends of which are rotatably connected to a third retainer. The bottom end of the third retainer is fixedly connected to the top end of the moving plate. Both ends of the second bidirectional threaded rod are fitted with second sliders, the top end of which is fixedly connected to the bottom end of the bracket.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since both ends of the second bidirectional threaded rod are fitted with second sliders, the rotation of the second bidirectional threaded rod can drive the second sliders to move, thereby adjusting the spacing of the bracket.

[0016] Furthermore, a third motor is mounted on one side of one of the third cages, and the output end of the third motor is connected to one end of the second bidirectional threaded rod.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by connecting the output end of the third motor to one end of the second bidirectional threaded rod, the second bidirectional threaded rod can be electrically rotated, thereby realizing the automatic adjustment of the bracket spacing.

[0018] Furthermore, a pair of third slide rods are slidably connected to the inner side of the second slider, and the two ends of the third slide rods are respectively fixedly connected to the inner side of the pair of third retainers.

[0019] The beneficial effect of adopting the above-mentioned further solution is that a pair of third slide rods are slidably connected to the inner side of the second slider, thereby restricting the movement direction of the bracket and ensuring that the spacing of the two brackets is adjusted synchronously and smoothly.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic mold adjustment device for injection molding machines, through the setting of the base plate and support seat, forms a stable basic support structure, ensuring that the device remains stable during mold adjustment. The height adjustment mechanism can adjust the height of the lifting plate, so that the mold reaches a precise installation position in the vertical direction. The translation mechanism drives the unidirectional threaded rod through the first motor, driving the moving block and the moving plate to move horizontally, realizing the adjustment of the mold's lateral position. The distance adjustment mechanism is used to adjust the spacing of the brackets to adapt to molds of different widths. The first sliding rod ensures the stability of the moving block during translation, avoiding positioning errors caused by offset. Since the first bidirectional threaded rod has first sliders mounted on both ends, the rotation of the first bidirectional threaded rod can drive the first sliders to move. The height of the lifting plate is adjusted through the hinge connection between the diagonal brace and the height-increasing block. The output end of the second motor... One end of the first bidirectional threaded rod is connected to the first bidirectional threaded rod, enabling its electric rotation and thus precisely adjusting the height of the lifting plate. A pair of second slide rods are slidably connected to the inner side of the first slider to prevent the first slider from shaking or shifting under the drive of the threaded rod. Second sliders are fitted at both ends of the second bidirectional threaded rod, allowing the second sliders to move when the second bidirectional threaded rod rotates, thereby adjusting the spacing of the brackets. The output end of the third motor is connected to one end of the second bidirectional threaded rod, enabling its electric rotation and thus automating the adjustment of the bracket spacing. A pair of third slide rods are slidably connected to the inner side of the second slider to restrict the direction of bracket movement, ensuring that the spacing of the two brackets is adjusted synchronously and smoothly. This invention effectively achieves lateral alignment adjustment of the mold, improves the alignment efficiency of the mold, and has high practical value. Attached Figure Description
