DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0033] Embodiment one:

[0034] Please refer to Figures 1-8, The existing demolding device is inconvenient to adjust the support width according to the actual size of the mold core when supporting the mold core due to different sizes of the mold core. The distance between the track car and the core mold is also fixed. Different sizes of the mold core result in different distances between the track car and the core mold, which leads to insufficient friction between the track car and the wall pipe, and the wall pipe cannot be demolded. In order to solve the technical problem, the embodiment discloses the following technical content: a polyethylene winding structure wall pipe demolding device, which comprises a base 1 and a stand 2 installed on the base 1. The upper end of the stand 2 is fixed with a plug-in rod 3 matched with the end positioning sleeve of the mold core. A lifting track car 4 is installed on the base 1, and a power module 5 is installed at the bottom of the lifting track car 4 to provide driving force. The upper end of the base 1 is sequentially provided with a first support part 6 and a second support part 7 from left to right. The first support part 6 and the second support part 7 are both provided with a photoelectric sensor 8 on the side facing the center of the base 1. A detection block 9 is installed on the side opposite to the photoelectric sensor 8 of the lifting track car 4. The first support part 6 and the second support part 7 are structurally identical, and the photoelectric sensor 8 on the first support part 6 and the second support part 7 is at the same height as the detection block 9 on the side edge of the lifting track car 4 from the base 1. The first support part 6 and the second support part 7 comprise a positioning column 13, and a gas cylinder 14 is fixed in the positioning column 13. The extension end of the gas cylinder 14 is fixed with a bearing block 15.

[0035] When the wall pipe needs to be demolded, the core mold and the wall pipe are lifted onto the lifting track car 4 by a travelling crane. Then the positioning sleeve at the end of the mold core is inserted into the plug-in rod 3 on the stand 2 to assist in positioning the mold core. The lifting track car 4 is controlled to move by the power module 5. After the lifting track car 4 moves, the wall pipe outside the core mold is dragged to move synchronously. When the detection block 9 on the side edge of the lifting track car 4 moves beyond the photoelectric sensor 8 on the first support part 6, the photoelectric sensor 8 transmits a signal to the executive element, and the executive element controls the gas cylinder 14 on the first support part 6 to open. After the gas cylinder 14 opens, the bearing block 15 moves upward and contacts the end of the core mold exposed from the wall pipe, thereby supporting the core mold. Thereafter, the lifting track car 4 continues to move under the control of the power module 5. After the lifting track car 4 moves, the wall pipe outside the core mold continues to be dragged to move synchronously. When the detection block 9 on the side edge of the lifting track car 4 moves beyond the photoelectric sensor 8 on the second support part 7, the photoelectric sensor 8 on the first support part 6 transmits a signal to the executive element, and the executive element controls the gas cylinder 14 on the second support part 7 to open. After the gas cylinder 14 opens, the bearing block 15 moves upward and supports the tail of the core mold, thereby improving the stability of the core mold after the wall pipe and the core mold are demolded.
