Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical lifting tools, and particularly relates to a lifting tool for the production of automobile plastic part molds. Background Technique

[0002] A lifting tool is a device for lifting heavy objects in a hoisting machine. The most commonly used lifting tool for lifting finished items is a hook. There are also other lifting tools such as lifting rings, lifting suction cups, tongs, and forklift tines. Lifting suction cups, tongs, forklift tines, etc. can be used as dedicated lifting tools on a crane for a long time, or can be used as replaceable auxiliary lifting tools hanging on the hook for temporary use, and are commonly used in multi-cargo type warehouses and yards to improve operation efficiency.

[0003] Currently, most lifting tools drive a screw rod to rotate through a motor inside them, so that the clamping plate on the nut moves horizontally, and then the mold is pressed against the fixing plate for clamping and fixing. This fixing method for the mold often has limited fixing efficiency and cannot quickly fix the mold on the lifting tool. Content of the Utility Model

[0004] The utility model provides a lifting tool for the production of automobile plastic part molds, aiming to solve the problem that the current fixing method for the mold often has limited fixing efficiency and cannot quickly fix the mold on the lifting tool.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A lifting tool for the production of automobile plastic part molds includes a support plate. A lifting ring body is installed at the top of the support plate.

The housing is located on the lifting mechanism and is connected to the lifting mechanism. A fixing plate is installed inside the housing. A gear is rotatably connected to the fixing plate. A first rack and a second rack are respectively engaged with the top and bottom of the gear. The first rack and the second rack are both slidably connected to the fixing plate. An L-shaped plate one and an L-shaped plate two are respectively installed on the first rack and the second rack; in this scheme, by setting the gear, when the gear rotates, it can drive the L-shaped plate one and the L-shaped plate two on the first rack and the second rack to approach or move away from each other, and then clamp molds of different lengths.

[0007] Preferably, the lifting mechanism includes a housing, a motor is installed inside the housing, a first lead screw and a second lead screw are respectively arranged on both sides of the motor, both the first lead screw and the second lead screw are rotationally connected to the housing, both the first lead screw and the second lead screw are in transmission connection with the output shaft of the motor, nuts are threadedly connected to the side walls of both the first lead screw and the second lead screw, lifting plates are connected to both the nuts, both the lifting plates are slidably connected to the housing, lifting columns are installed at the bottoms of both the lifting plates, and each lifting column is fixedly connected to the outer housing; in this solution, by setting the motor, when the motor works, it can drive the first lead screw and the second lead screw to rotate simultaneously, and then drive the two lifting plates to rise or fall simultaneously through the two nuts, so as to adjust the height of the clamping mechanism.

[0008] Preferably, two driving wheels are sleeved and installed on the output shaft of the motor, a first driven wheel and a second driven wheel are sleeved and installed on the side walls of the first lead screw and the second lead screw respectively, the first driven wheel is in transmission connection with one of the driving wheels through a first belt, and the second driven wheel is in transmission connection with the other driving wheel through a second belt; in this solution, by setting two driving wheels and two driven wheels, the device can drive the two lead screws to rotate simultaneously with only one motor. Compared with the case where two motors drive the two lead screws to rotate respectively, the device can save the setting of the driving source.

[0009] Preferably, guide columns are vertically arranged inside both the lifting plates, each guide column is fixedly connected to the housing, a guide sleeve is sleeved on each guide column, and the two lifting plates are respectively fixedly connected to the two guide sleeves; in this solution, by setting the guide columns and the guide sleeves, the guide columns and the guide sleeves can limit the freedom of rotation of the nuts, and at the same time provide guidance for the vertical movement of the lifting plates.

[0010] Preferably, a first guide groove and a second guide groove are provided on the front side wall of the fixed plate, two first guide wheels are provided inside the first guide groove, and the two first guide wheels are respectively connected to both ends of the first rack, two second guide wheels are provided inside the second guide groove, and the two second guide wheels are respectively connected to both ends of the second rack; in this solution, by setting the first guide groove and the first guide wheels, this structure can provide guidance for the lateral movement of the first rack; and the setting of the second guide groove and the second guide wheels can provide guidance for the lateral movement of the second rack.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] 1. By setting up a clamping mechanism, when the gear inside the clamping mechanism rotates, it will drive the first rack and the second rack to move horizontally on the fixed plate, thereby adjusting the distance between the first L-shaped plate and the second L-shaped plate at the same time to clamp molds of different lengths. Compared with the situation where the first L-shaped plate can move while the second L-shaped plate cannot move, this device can improve the clamping efficiency of the mold and quickly fix the mold on the lifting tool.

[0013] 2. By setting up a lifting mechanism, when the motor inside the lifting mechanism works, it can drive the first lead screw and the second lead screw to rotate simultaneously, and then make the two lifting plates rise or fall simultaneously through two nuts, thereby adjusting the height of the clamping mechanism to expand the clamping range of the clamping mechanism of this device for the mold. And this lifting method can reduce the setting of the motor on the premise of driving the two ends of the clamping mechanism to descend, so as to achieve the purpose of saving energy.
