Description

Technical Field

[0001] The utility model relates to the technical field of positioning equipment, in particular to a positioning tool. Background Art

[0002] Plastic injection molding is a method of producing plastic products. The molten plastic is injected into the plastic product mold under pressure, and then cooled and molded into various desired plastic parts. There are mechanical injection molding machines specifically used for injection molding. The most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc.

[0003] During the injection molding process of the tailgate inner panel, it is usually necessary to install a positioning tool on the workbench of the molding machine for the precise positioning of the clamp that presses and fixes the injection molded parts to ensure that the dimensional accuracy of the molded parts meets the molding requirements. Currently, the most commonly used method is to lift it with the help of a manual assisted hydraulic lift forklift with the help of a belt and a lever, and then push it onto the workbench of the molding machine. After calibrating it with a dial indicator, the clamp is locked. During the calibration process, the locking bolts need to be repeatedly loosened, and the clamp body is hit with the help of a heavy hammer to achieve the installation accuracy requirements. This process wastes a lot of time, resulting in low installation efficiency of the clamp body, especially in the process of changing production, which is more time-consuming and labor-intensive. Sometimes it even takes a day to carry out repeated calibration and debugging operations, which greatly reduces the production efficiency of the injection molding machine. Utility Model Content

The utility model takes the installation and positioning of the clamp of the injection molding machine as an example to explain its usage method in detail. When the clamp needs to be installed and positioned, first start the output rod of the telescopic push rod 307 to extend it to a height position where the cross-section of its output end is 2-5mm higher than the upper surface of the positioning table 301. Then start the motor of the linear slide to rotate until the screw rod is driven to rotate until the driving slider pushes the positioning correction rod 305 along the slide rail of the linear slide until the end of the positioning correction rod 305 is at a distance from the geometric center of the positioning table 301 equal to half the width and length of the clamp. Then the operator lifts the clamp to be installed with the help of an overhead crane or a lifting crane, and pushes it to the front of the guide groove plate 200, so that the length edge of the clamp is located at the same height as the guide groove plate. The clamp body is then pushed inwardly until the rear side wall of the clamp body contacts the positioning correction rod 305, and then the output rod of the telescopic push rod 307 is retracted to slowly drop the clamp body to the positioning hole at the bottom of the clamp body and insert it into the positioning platform 301, and then the mounting bolts on the clamp body are locked to achieve the correction and installation of the clamp body. The utility model can realize the rapid centering and positioning of the clamp body through the combined action of the guide slot plate 200 on the positioning tooling, the positioning platform 301, the pin 302 and the positioning correction rod 305, and there is no need to repeatedly remove the bolts and knock the clamp body to achieve the positioning and centering accuracy requirements during the fixture replacement and debugging or installation and debugging process. The clamp body can be installed and positioned quickly and efficiently, which greatly saves the calibration time and improves the production efficiency of the injection molding machine.

[0027] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
