Detailed Description

The utility model relates to a steel socket base mold of a concrete drain pipe, which comprises a first half ring 1 and a second half ring 2, wherein a first circumferential outer ring table 3 is arranged on the periphery of the first half ring 1, and two ends of the first outer ring table 3 extend out of the end part of the first half ring 1; a second outer ring table 4 is arranged at a position (i.e. the same height as the first outer ring table 3) corresponding to the second half ring 2, a step part 41 is arranged on the second outer ring table 4, and the tail end of the first outer ring table 3 is lapped on the step part 41; the inner Zhou Jun of the first semi-ring 1 and the second semi-ring 2 is provided with an inner ring table 5; through holes A are formed in the end part of the first outer ring table 3 and the corresponding position of the step part 41; the first half ring 1 and the second half ring 2 are fixedly connected into a whole by bolts 6 penetrating through the through holes A.

When the utility model is used, the first half ring 1 and the second half ring 2 of the steel socket base mould are butted and folded together, then the bolts 6 are inserted into the through holes A corresponding to the first outer ring table 3 and the step part 41 to fix the first half ring 1 and the second half ring 2 together to form the steel socket base mould, and then the core mould of the concrete drain pipe component is assembled together with other moulds, thus the drain pipe component can be poured. When the concrete drain pipe member is to be demolded after solidification, firstly removing the bolts 6, and then slightly suspending and hanging the upper part of the die together with the concrete member, wherein the die of the base of the steel socket faces downwards; then, the first outer ring table 3 of the first semi-ring 1 and the second outer ring table 4 of the second semi-ring 2 are lightly knocked by a rubber hammer without using an iron hammer, so that the first semi-ring and the second semi-ring can be respectively and automatically separated to separate a base die from a component, the demolding mode of downward knocking by the aid of the demolding slope of the die at the present stage is adjusted to a mode of left and right separated demolding, damage to a component socket can be avoided, and the problem that the component socket is damaged and cracked due to gravity knocking demolding is completely eradicated.
