In the above-mentioned process, the wooden block for forming the riser is installed by a worker on site, and problems such as missing or installation dislocation are likely to occur, thereby easily causing reworking.
At present, the Chinese patent is searched, a detachable heating insulating riser is disclosed as No. CN208976766U, the insulating riser comprises a fireproof layer, a heating layer and an insulating layer, a through hole is formed in the middle of the insulating riser, the insulating layer is an insulating riser inner layer, the heating layer is arranged outside the insulating layer, the inner wall of the heating layer is attached to the outer wall of the insulating layer, the fireproof layer is arranged outside the heating layer, the inner wall of the fireproof layer is attached to the outer wall of the heating layer, the insulating riser further comprises a tightening rope, the tightening rope is tied to the middle part of the fireproof layer, a buckle is arranged at the outer edge of the upper part of the insulating riser, and the insulating riser can be conveniently installed and removed and is repeatedly used; but cannot solve the problems of neglected installation or misplacement of installation of an installer.
The utility model comprises the following steps:
in view of the above-mentioned shortcomings of the prior art, the present utility model aims to provide a forming die for the outer peripheral surface of a pump casing of a pipeline, which is reasonable in design, and is beneficial to avoiding the problems of missing or misplacement of a mounting block serving as a riser by a worker.
The utility model relates to a forming die for the outer peripheral surface of a pipeline pump shell, which is characterized in that: the novel riser pipe pump comprises an upper die and a lower die, wherein the upper die and the lower die are used for forming the outer peripheral surface of a pump casing of a pipe, a first insert used for forming the riser is detachably connected to the position of the riser, a bump is arranged on the lower bottom surface of the first insert, a concave groove which is matched with the bump relatively is formed in the upper die, and the bump is connected with the concave groove in a transition fit mode.
Further, the flange of the upper die is detachably connected with a flange patch block.
Further, the first insert is trapezoidal, one end of the first insert far away from the upper die is larger than one end of the first insert close to the upper die in size, and the cross section of the first insert is rectangular.
According to the application method of the forming die for the outer peripheral surface of the pipeline pump shell, when the upper die for forming the outer peripheral surface of the pipeline pump shell is placed into the sandbox, as the first insert is in transition fit with the concave groove through the first convex block, the first insert is tightly connected with the upper die, and the first insert is placed into the sandbox along with the upper die, so that the problem of missing placement or non-alignment (dislocation) of placement of the first insert serving as a riser is avoided.
Description of the drawings:
the utility model is further described with reference to the drawings;
FIG. 1 is a schematic view of the front view construction of the present utility model;
FIG. 2 is a schematic diagram of an exploded front view of the present utility model;
FIG. 3 is a front view of a flange patch;
fig. 4 is a side view of a flange patch.
The specific embodiment is as follows:
the utility model is further described below with reference to the drawings and the detailed description.
The forming die for the outer peripheral surface of the pipeline pump shell comprises an upper die 1 and a lower die 2 which are used for forming the outer peripheral surface of the pipeline pump shell, wherein a first insert 3 used for forming a riser is detachably connected to the upper die 1 at the position of the riser, the first insert is trapezoid, one end of the first insert, which is far away from the upper die, is larger than one end, which is close to the upper die, of the first insert, and the cross section of the first insert is rectangular.
The lower bottom surface of the first insert 3 is provided with a convex block 4, the upper die is provided with a concave groove 5 which is matched with the convex block relatively, the convex block is connected with the concave groove in a transition fit manner, the first insert 3 is connected with the upper die during normal moving, and before molten iron casting, the upper die and the first insert are respectively separated from the sandbox.
Because the flange position 7 of the upper die is far away from the riser position, in order to reduce casting defects, the flange position of the upper die is detachably connected with a flange patch block 6 which is in plug-in fit with the flange of the upper die, the flange patch block is an inclined wedge, the lower part of the flange patch block is provided with a concave arc channel 8, and the concave arc channel 8 is in plug-in fit with a semicircular shaft part 9 beside the flange position 7 of the upper die.
According to the application method of the forming die for the outer peripheral surface of the pipeline pump shell, when the upper die for forming the outer peripheral surface of the pipeline pump shell is placed into the sandbox, as the first insert is in transition fit with the concave groove through the first convex block, the first insert is tightly connected with the upper die, and the first insert is placed into the sandbox along with the upper die, so that the problem of missing placement or non-alignment (dislocation) of placement of the first insert serving as a riser is avoided.
While the foregoing is directed to the preferred embodiment, other and further embodiments of the utility model will be apparent to those skilled in the art from the following description, wherein the utility model is described, by way of illustration and example only, and it is intended that the utility model not be limited to the specific embodiments illustrated and described, but that the utility model is to be limited to the specific embodiments illustrated and described.
