Description

Technical Field

[0001] The utility model belongs to the field of pipe processing equipment, in particular to a die opening adjustment auxiliary device for an empty pipe extruder. Background Art

[0002] The empty tube extruder is a common equipment for processing plastic pipes, which can be used to process pipes of various specifications. When switching between different specifications of pipe production tasks, in order to adjust the wall thickness of the pipe in all directions, the position of the mold core needs to be corrected. The traditional adjustment method is to use a marker to mark the pipe along the axial direction of the pipe, cut the pipe after cooling, and measure the wall thickness of the pipe section in all directions to determine the adjustment direction of the mold. This method is not suitable for the fast processing of blow molding empty tube process. Because the blow molding empty tube has a high running speed, the traction speed can reach 50 meters / minute. And the cutting length is short, about 120-300mm / piece. After the fast-moving empty tube is cut, the collision with the cutter protection cover may cause the empty tube to fall in an inverted direction, and the marks on the tube wall are easy to confuse. In addition, when using a handheld marker to mark the empty tube, due to different personal operating proficiency, it may also cause the surface of the empty tube to deform, affecting the accuracy of the interface thickness measurement. Therefore, this method is not conducive to the adjustment of the mold core. Utility Model Content

[0030] It is worth mentioning that the adjustment of the inner core of the mold is to adjust the wall thickness of the pipe by changing the position of the adjusting bolts outside the mold, or to adjust the tightness of the adjusting bolts to adjust the wall thickness of the pipe. For example, the mold gap adjustment bolts of the empty tube extruder are 6, and two markers are fixed according to the positions of the two fixing bolts of the mold. An auxiliary device for adjusting the die opening of the empty tube extruder is set at the rear end of the tube extrusion mold, and the surface of the tube is marked with a marker. The tube is cut off at the rear end of the empty tube processing unit, and the wall thickness of the tube is measured with a vernier caliper or micrometer. The position of the marker corresponds to the position of the adjusting bolts outside the mold. According to the results of each marking and wall thickness measurement, the position of the adjusting bolts outside the mold is adjusted in a targeted manner, and the position of the adjusting bolts outside the mold is adjusted according to the measured value. Repeat the steps until the wall thickness of the tube is uniform. The speed of mold adjustment is significantly improved.

[0031] In one embodiment, the angle between the two clamping sections is adjusted by adjusting the relative distance between the first clamping section and the second clamping section.

In addition, the pen holder can slide on the supporting section to adjust the position of the marker pen. For example, the pen holder has a cavity, and the two pen holders are respectively placed on the outer surfaces of the first clamping section and the second clamping section, that is, the pore fit.

[0032] In one embodiment, the support frame includes a first tube body and a second tube body that are sleeve-connected, the first tube body is vertically arranged with the base, the outer wall of the end of the first tube body away from the base is movably connected with the inner cavity peripheral wall of the second tube body, and the outer surface of the end of the first tube body away from the base is provided with a first positioning hole, and the outer surface of the second tube body is provided with a row of second positioning holes along the axial direction, and the relative positions of the first tube body and the second tube body are fixed by fasteners that pass through one of the second positioning holes and the first positioning holes in sequence.
