To achieve these goals, the technical solution of the utility model：
A kind of beater or beat-up skinning structure, including beater or beat-up body, the beater or beat-up body have internal PU foaming layers and
Closely bond the PU films in appearance in the PU foaming layers, wherein, the PU foaming layers of the beater or beat-up body and PU films integrated injection molding into
Type；In the beater or beat-up body circumferential end faces have several connection sheets and be correspondingly arranged in the connection sheet and in open it is cricoid
Connecting hole is arc-shaped transition connection between the connection sheet and the beater or beat-up body.
Further, there is reinforcing rib on the arc-shaped crossover position between the connection sheet and the beater or beat-up body
Item, the strengthening rib strip on the inside of the connection sheet by extending on the beater or beat-up body.
Further, the strengthening rib strip quantity is at least two, and the strengthening rib strip and the connection sheet, beater or beat-up sheet
Body integrated injection molding.
A kind of making mold of beater or beat-up skinning structure including die ontology, has beater or beat-up type on the die ontology
Chamber, and several aspirating holes being connected in the beater or beat-up cavity are provided on the die ontology, aspirating hole other end connection
There is pumped vacuum systems；There is reserved material position around beater or beat-up cavity on the die ontology, and it is circumferentially fixed in the die ontology
There is the hook available for locking positioning PU films in position.
Further, the reserved material position width is 2~5mm.
Further, the aspirating hole connected in the beater or beat-up cavity include flanging along in the beater or beat-up cavity or
The gap extended corresponding to dog-ear or pore.
The beneficial effects of the utility model：It is simple in sturcture, ingenious in design, pass through the water resistancees of PU films and PU foaming layers
Property combination substantially increases the water resistance of beater or beat-up, while also takes into account aesthetics and sound absorption properties, and using unique connection
Location structure improves the efficiency of assembling and assembly performance of product, reduces and makes precision and technology difficulty；In addition, by independently grinding
The making mold of hair, it is easy to operate by PU films and PU foaming layers in carrying out technological operation in die ontology, and good moldability, it fits
Preferably promote.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic diagram that the utility model makes mold.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of beater or beat-up skinning structure as shown in Figure 1 and Figure 2, including beater or beat-up body 1, which has
Internal PU foaming layers 10 and PU films 11 in the PU foaming layers 10 in appearance are closely bonded, wherein, the beater or beat-up body 1
11 integrated injection molding of PU foaming layers 10 and PU films；In 1 circumferential end faces of beater or beat-up body there are several connection sheets and be correspondingly arranged
It is connected in the connection sheet and in cricoid connecting hole is opened, being arc-shaped transition between connection sheet and beater or beat-up body 1.
Specifically, with reference to the light of PU foaming layers 10, attracting performance is good and the water resistance of PU films 11, PU films 11 are coated
In 10 appearance of PU foaming layers, can effectively waterproof, can also take into account beautiful and sound absorption properties；Meanwhile opening by connection sheet and thereon
The unique design of ring connecting hole so that during assembling, be attached using open loop connecting hole as location hole, reduce assembly precision and
Technique productions difficulty, improves work efficiency, and reduces cost of manufacture, very useful.
In order to ensure the use structural strength of connection sheet and bonding strength, the circular arc between connection sheet and beater or beat-up body 1
There is strengthening rib strip, the strengthening rib strip on the inside of connection sheet by extending on beater or beat-up body 1, and the reinforcement on shape crossover position
