Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for injection molding machines, specifically an assembly tool for adjusting mold nuts in injection molding machines. Background Technology

[0002] In existing injection molding machines, the inner ring of the mold adjustment nut is connected to the tie rod via a thread, and the outer ring achieves the mold adjustment action through gear meshing. However, when assembling the mold adjustment nut, it is necessary to screw the nut into the thread on the mold adjustment end of the tie rod. Due to the long thread, the weight of the nut, and the large diameter of the internal thread, the assembly and screwing is relatively laborious and inefficient, causing great inconvenience to the installation and disassembly of the mold adjustment nut. Summary of the Invention

[0003] This invention provides an assembly tool for an injection molding machine mold adjusting nut. It has a simple structure and can solve the problems of the existing mold adjusting nut being difficult to install and disassemble, and having low efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an assembly tool for an injection molding machine mold adjusting nut, comprising a mounting plate, on which multiple guide bushings are mounted, the axes of the guide bushings being perpendicular to the mounting plate, and a guide shaft connected to the injection molding machine passing through the guide bushings; a drive shaft passing through the mounting plate, the drive shaft and the mounting plate being in a rotatable fit, a mold adjusting nut drive gear mounted at the first end of the drive shaft, the mold adjusting nut drive gear meshing with the mold adjusting nut, and a torque tool connector provided at the second end of the drive shaft. The relative position of the mold adjusting nut drive gear and the mold adjusting nut can be fixed by the mounting plate, and the drive shaft can move along the guide shaft while being driven to rotate, easily installing and removing the mold adjusting nut.

[0005] Preferably, at least one bearing is sleeved on the outer side of the drive shaft at a position corresponding to the mounting plate, and a bearing drive shaft fixedly connected to the mounting plate is sleeved on the outer side of the bearing, which can satisfy the stable rotation of the drive shaft.

[0006] Preferably, a bearing sleeve is fitted onto the outer side of the bearing drive shaft, and the mounting plate is clamped between the bearing drive shaft and the bearing sleeve. An axial stop block for axial blocking of the bearing is installed on one axial side of the bearing sleeve, which can ensure the secure installation of the bearing drive shaft and the bearing.

[0007] Preferably, the mounting plate has multiple universal ball seats installed on the end face of the same side as the mold adjusting nut drive gear, which are used to contact the axial end face of the mold adjusting nut, thus ensuring the stability of the mounting plate movement.

[0008] Preferably, the end of the torque tool connector is connected to a torque multiplier assembly, which can reduce the force required by the operator to turn the mold adjusting nut drive gear and improve operating efficiency.

[0009] Preferably, the torque multiplier assembly includes a torque multiplier connected to a torque tool connector and a torque multiplier bracket for fixing the torque multiplier. The torque multiplier bracket is connected to a mounting plate via a pin, which facilitates the installation and fixing of the torque multiplier.

[0010] Preferably, at least one fixed handle is installed on the side wall of the mounting plate away from the drive gear of the mold adjusting nut, which facilitates operation to push the mounting plate to move along the guide shaft.

[0011] Preferably, the mounting plate has a tie rod clearance hole at the position corresponding to the mold adjusting nut, which will not affect the movement of the mold adjusting nut on the tie rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] With a simple structure, the relative position of the adjusting nut drive gear and the adjusting nut can be fixed by the mounting plate. While driving the transmission shaft to rotate, it can move along the guide shaft. Moreover, an electric wrench can be used to engage the torque multiplier. By utilizing the torque amplification effect of the multiplier and the gear meshing action of the pinion, the adjusting nut can be assembled into place with less force, improving work efficiency. In addition, this tool can not only be used for nut assembly operations, but also for nut disassembly operations during rework. By changing the matching pinion and adjusting the corresponding hole position on the mounting plate, this tool can also be used for assembling and disassembling nuts with similar structures.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] On existing injection molding machines, adjusting nuts are installed on the tie rods. During operation, a fixed adjusting mechanism is installed on the injection molding machine. However, the installation and removal of the adjusting nuts require manual operation by rotating the nuts on the relatively long tie rods to move their lateral position. The nuts are heavy and have large internal thread diameters, making them very difficult to turn. Moreover, for injection molding machines with large tonnage, multiple people are often needed to slowly install and remove the adjusting nuts. Currently, there is no dedicated device on the market for installing and removing adjusting nuts, so there is an urgent need for a dedicated device to solve this problem.

[0025] like Figure 1-7As shown, this invention addresses the problem of laborious and inefficient installation and disassembly of existing mold-adjusting nuts by providing the following technical solution: An assembly tool for an injection molding machine mold-adjusting nut includes a mounting plate 3. Multiple guide bushings 12 are mounted on the mounting plate 3, with their axes perpendicular to the mounting plate 3. A guide shaft 1, connected to the injection molding machine, passes through the guide bushing 12. A drive shaft 4 passes through the mounting plate 3, and the drive shaft 4 and mounting plate 3 are in a rotatable fit. A mold-adjusting nut drive gear 2 is mounted on the first end of the drive shaft 4, meshing with the mold-adjusting nut. A torque tool connector 16 is provided on the second end of the drive shaft 4. The mounting plate 3 can fix the relative position of the mold-adjusting nut drive gear 2 and the mold-adjusting nut, driving the drive shaft 4... While rotating, it can move along the guide shaft 1, easily installing and removing the mold adjusting nut. Specifically, the mold adjusting nut drive gear 2 is connected to the transmission shaft 4 via a flat key 8. At the same time, a gear retaining ring 9 is provided axially between the mold adjusting nut drive gear 2 and the transmission shaft 4. Guide bushings 12 are installed at both ends of the mounting plate 3. Lubricant can be placed between the guide shaft 1 and the guide bushing 12. The guide bushing 12 is connected to the mounting plate 3 via screws 13. The torque tool connector 16 can be a wrench socket. In use, an electric wrench can be used to directly drive the torque tool connector 16 and the transmission shaft 4 to rotate, thereby driving the mold adjusting nut drive gear 2 to rotate and driving the mold adjusting nut to move axially along the pull rod. At the same time as the mold adjusting nut moves axially, the mounting plate 3 also moves axially along the guide shaft 1.

[0026] To achieve stable rotation of the drive shaft 4, at least one bearing 5 is sleeved on the outer side of the drive shaft 4 at a position corresponding to the mounting plate 3. A bearing drive shaft 6, fixedly connected to the mounting plate 3, is sleeved on the outer side of each bearing 5. Specifically, four bearings 5 ​​can be arranged side-by-side, providing sufficient support. Simultaneously, a bearing sleeve 10 is sleeved on the outer side of the bearing drive shaft 6. The mounting plate 3 is sandwiched between the bearing drive shaft 6 and the bearing sleeve 10. An axial stop block 11 is installed on one axial side of the bearing sleeve 10 to axially block the bearing 5, ensuring a secure installation of the bearing drive shaft 6 and the bearing 5.

[0027] In order to move the mounting plate 3 while abutting the mold adjusting nut, a plurality of universal ball seats 14 are installed on the end face of the mounting plate 3 on the same side as the mold adjusting nut drive gear 2 for contacting the axial end face of the mold adjusting nut. The universal ball seats 14 can rotate freely, which can ensure the stability of the movement of the mounting plate 3.

[0028] To further reduce effort, the end of the torque tool connector 16 is connected to a torque multiplier assembly 17, which can reduce the force required by the operator to turn the mold adjustment nut to drive the gear 2 and improve operating efficiency. The torque multiplier is a common device in mechanical tools and is based on existing technology. Its specific structure and principle will not be described here, and it can be freely selected in the market.

[0029] As a specific embodiment of the torque multiplier assembly 17, the torque multiplier assembly 17 includes a torque multiplier connected to the torque tool connector 16 and a torque multiplier bracket for fixing the torque multiplier. The torque multiplier bracket is connected to the mounting plate 3 through a pin 18 to facilitate the installation and fixing of the torque multiplier. An R-type spring pin 19 is provided at the tail end of the pin 18.

[0030] To facilitate the movement of the mounting plate 3, at least one fixed handle 15 is installed on the side wall of the mounting plate 3 away from the mold adjusting nut drive gear 2, which facilitates the operation of pushing the mounting plate 3 to move along the guide shaft 1. At the same time, a tie rod clearance hole 20 is opened on the mounting plate 3 at the position corresponding to the mold adjusting nut, which will not affect the movement of the mold adjusting nut on the tie rod, and the universal ball seat 14 can be evenly arranged around the tie rod clearance hole 20.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
