Technical field
The present invention relates to a kind of dismantling device of double-wall corrugated pipe mold inwall mouth mould.
Background technology
Double-wall corrugated pipe mold comprises the interior wall mould that forms inwall and the outer wall mould that forms outer wall, interior wall mould comprises inwall mouth mould, as shown in Figure 1, it is cylindrical tube shape, one end has internal thread, the other end is the horn-like of enlarging, and outer wall is with circumferential groove, and when mounted, the outer wall of this inwall mouth mould is to be close on the inwall that is close to outer wall core, therefore cannot utilize instrument to carry out the application of force to the outer wall of inwall mouth mould, so the dismounting problem of this inwall mouth mould becomes utilizes this mould to produce the problem of needing solution in double-wall corrugated pipe process badly.
Summary of the invention
For the technical deficiency of above-mentioned existence, the object of this invention is to provide a kind of dismantling device of double-wall corrugated pipe mold inwall mouth mould, utilize its can be quick, convenient, effortlessly inwall mouth mould is carried out to dismounting.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of dismantling device of double-wall corrugated pipe mold inwall mouth mould, described inwall mouth mould is cylindrical tube shape, its one end has internal thread, the other end is the horn-like of enlarging, this dismantling device comprises the circumferentially ringfeder of spreading or contraction of one end, be arranged on described ringfeder inside can indentation or stretch out and control described ringfeder spreading or the telescopic core of contraction, the screw rod that drives described telescopic core to move, on described screw rod, be provided with external diameter and become large circumferential fin, the described fin pressing plate axial location that the other end with described ringfeder is fixedly connected by, described screw rod is threaded with described telescopic core, described telescopic core is extended or retracted by the rotation forward or backwards of described screw rod, the outer wall of the described ringfeder in spreading state is pushed against on the inwall of described inwall mouth mould, on described ringfeder, be provided with the operating portion of being convenient to it to be rotated.
Preferably, described ringfeder can spreading end have be circumferentially equally spaced, axially extended gap slot.
Preferably, described operating portion is for extending vertically a plurality of blind holes of the non-spreading end end face that is opened in described ringfeder.
Preferably, the outer wall of one end away from described screw rod of described telescopic core has and is cone shape the first spigot surface, and becomes gradually large to the direction external diameter of the screw rod away from described.
Preferably, described ringfeder can spreading end inwall there is the second spigot surface matching with the first described spigot surface.
Beneficial effect of the present invention is: the ringfeder by can spreading is pushed against on the inwall of inwall mouth mould, make ringfeder circumferentially relative fixing with inwall mouth mould, therefore make the power of its rotation just can drive inwall mouth mould to rotate by ringfeder is applied, and then realize dismounting, tool construction is simple, simple operation, dependable performance can complete the dismounting of inwall mouth mould quick, convenient, time saving and energy savingly.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of inwall mouth mould;
Accompanying drawing 5 is the axial cross-sectional schematic of screw rod in the dismantling device of double-wall corrugated pipe mold inwall mouth mould of the present invention.
In accompanying drawing: 1, ringfeder; 2, telescopic core; 3, screw rod; 4, fin; 5, pressing plate; 6, gap slot; 7, the first spigot surface; 8, the second spigot surface.
The specific embodiment
Below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
If accompanying drawing 2 is to as shown in accompanying drawing 5, a kind of dismantling device of double-wall corrugated pipe mold inwall mouth mould, this inwall mouth mould is cylindrical tube shape, its one end has internal thread, the other end is the horn-like of enlarging, this dismantling device comprises the circumferentially ringfeder 1 of spreading or contraction of one end, be arranged on ringfeder 1 inside can indentation or stretch out the telescopic core 2 of controlling ringfeder 1 spreading or contraction, the screw rod 3 that drives telescopic core 2 to move, on screw rod 3, be provided with external diameter and become large circumferential fin 4, fin 4 pressing plate 5 axial location that the other end with ringfeder 1 is fixedly connected by, screw rod 3 is threaded with telescopic core 2, telescopic core 2 is extended or retracted by the rotation forward or backwards of screw rod 3, on ringfeder 1, be provided with the operating portion of being convenient to it to be rotated.
Further preferably, can spreading end having circumferentially of ringfeder 1 is equally spaced, axially extended gap slot 6, and when ringfeder 1 is during in spreading state, gap slot 6 becomes large; When ringfeder 1 is during in contraction state, gap slot 6 restores, operating portion is for extending vertically a plurality of blind holes of the non-spreading end end face that is opened in ringfeder 1, the outer wall of one end away from screw rod 3 of telescopic core 2 has and is cone shape the first spigot surface 7, and to the direction external diameter away from screw rod 3, become gradually greatly, ringfeder 1 can spreading end inwall there is the second spigot surface 8 matching with the first spigot surface 7.
Use procedure: by can coaxially stretching in inwall mouth mould under the state shrinking by spreading end of the ringfeder of this instrument 1, then turn screw rod 3, make telescopic core 2 indentations, order about ringfeder 1 spreading, like this, the state of the inwall of the outer wall of ringfeder 1 and inwall mouth mould in mutually pushing against, now by instrument, rotate ringfeder 1, just can drive the rotation of inwall mouth mould, realize dismounting, and then turn screw rod 3, telescopic core 2 is stretched out, order about ringfeder 1 and shrink, like this, can make ringfeder 1 and inwall mouth mould be separated.
The spreading end of above-mentioned ringfeder 1 also can adopt the material of flexible great friction coefficient to make, and control its spreading or contraction equally, and stretching out of telescopic core 2 is to control by screw rod 3 with indentation equally by telescopic core 2.
Design of the present invention is that the ringfeder 1 by can spreading is pushed against on the inwall of inwall mouth mould, make ringfeder 1 circumferentially relative fixing with inwall mouth mould, therefore make the power of its rotation just can drive inwall mouth mould to rotate by ringfeder 1 is applied, and then realize dismounting, tool construction is simple, simple operation, dependable performance can complete the dismounting of inwall mouth mould quick, convenient, time saving and energy savingly.
