In view of prior art scenario, to solve the deficiencies in the prior art, the purpose of the utility model is to provide a kind of PU days Window wrapping mold.

To achieve the above object, the utility model is using a kind of following technical solution:

A kind of PU skylight wrapping mold, including cope plate, lower template, moving template component, glass, the first sealant, second Sealant, third sealant and reinforcing rib.

The cope plate is rectangular block shape part, and medial surface edge one week is equipped with the first groove of parallel arranged, the second groove, the Three grooves and the 4th groove, first groove, the second groove, third groove and the 4th groove cross section are different square Shape.

The lower template is rectangular block shape part, and medial surface edge one week the 5th groove and the 6th equipped with parallel arranged are recessed Slot, the 5th groove and the 6th groove cross section bottom are arc-shaped.

The moving template component surrounds four frame shapes by several moving templates, four between the cope plate and lower template Week a type chamber is formed with cope plate and lower template, the moving template component is equipped with a raised line towards type chamber on one side.

Place the glass of bound edge in need in type chamber center.

First sealant, the second sealant and third sealant be closure strip, be respectively arranged on first groove, In 4th groove and the 5th groove, first sealant, the one side of the second sealant and third sealant towards glass with Glass fits closely.

6th groove, the raised line of the moving template component and cope plate have collectively constituted the injection die cavities communicated.

The reinforcing rib is in long strip, a long side inward curl, is set in the 6th groove, is located at lower template Two sides.

Further, first sealant cross section upper and lower ends are arc-shaped.

Further, second sealant cross section upper end is at an angle, and lower end is straight.

Further, third sealant cross section lower end is arc-shaped.

Further, the sealant material selection EPDM.

Beneficial effect

Sealant is equipped in 4th groove and the 5th groove at the utility model injection die cavities both ends, the material of sealant is Ethylene propylene diene rubber (EPDM), the overlap and flash effectivelying prevent between template ironware, the 6th groove is interior to be equipped with reinforcing rib, After PU injection molding, intensity can be effectively improved, when injection molding, the center of type chamber is vacuumized, and generates bubble when can effectively prevent PU molding.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

Embodiment:

As shown in Figure 1, a kind of PU skylight wrapping mold, including cope plate 1, lower template 2, moving template component 3, glass 5, One sealant 6, the second sealant 7, third sealant 8 and reinforcing rib 9.

As shown in Figure 3 and Figure 4, the cope plate 1 is rectangular block shape part, and medial surface edge is equipped with parallel arranged first in one week Groove 41, the second groove 42, third groove 43 and the 4th groove 44, first groove 41, the second groove 42, third groove 43 It is in different rectangle with 44 cross section of the 4th groove.
