103rd, the arcuate structure that intrados 104, first side 105 and second side 106 form, first side 105 and bottom surface 102 it
Between, be connected by slotted eye face 107 between second side 106 and bottom surface 102, it is more when multiple adjacent split matrixs 1 splice
Individual slotted eye face 107 surrounds the through hole 3 of hollow ball；Slotted eye face 107 as shown in Figure 1 for two split matrixs 1 of episphere is with
The slotted eye face 107 of two split matrixs 1 of hemisphere surrounds a complete through hole 3.
What deserves to be explained is with respect to provided with extending internally in first side 105 and second side 106 in the present embodiment
Cavity 108, specially uniform intervals offer the cavity 108 of inwardly corresponding extension, as shown in Figure 3, first along its length
Offer 4 cavitys 108 on side 105 and second side 106 respectively, and cavity 108 along with extrados 103 and intrados 104
Concentric arcuate directions extension so that bearing of trend of the thickness along cavity 108 beyond the inwall of cavity 108 is consistent, and the
The cavity 108 corresponding with second side 106 of cavity 108 in one side 105 does not connect mutually, four groups of relative cavitys of both sides
The distance between 108 keep equal, as shown in Figure 3 and Figure 4 so that the thickness between both sides cavity 108 also keeps uniformity.
Split matrix 1 is made up of eps foam bead in the present embodiment, by opening up cavity 108 inside split matrix 1,
On the one hand the mass of split matrix 1 can be effectively reduced, is easy to processing and subsequently splices and combines, and substantially saved and processed raw material,
Reduce production cost, it is often more important that, reduced by the solid thickness for setting split matrix 1 of cavity 108, used
When high-temperature steam carries out processing and forming to matrix, it can ensure that foam beads are cooked shaping by surface steam rapidly, improve split pattern
The shaping qualification rate of piece 1；And split matrix 1 designs according to solid construction, then often occur in production practices in foam beads
Center portion position is difficult to cook, and causes matrix to be molded the problem of difficult.
It should be noted that to realize the efficient shaping to split matrix 1, and ensure that the overall structure of split matrix 1 is strong
Degree and follow-up performance, the design for cavity 108 have strict requirements, specifically as shown in figure 5, the thickness of split matrix 1
Spend for L1, cavity 108 is circular cavity, the distance between diameter L2=1/2L1, two neighboring cavity 108 L3=1/ of cavity 108
2L1, and the distance between the center of cavity 108 and extrados 103 be equal between the center and intrados 104 away from
From that is, cavity 108 is located at the center of first side 105 and the width of second side 106, ensures that the both sides of cavity 108 are thick
The uniformity of degree.
The present embodiment is by many rational designs such as the distributing position of cavity 108, specification size, bearing of trends, making
The Forming Quality of split matrix 1 it is good, processing cost is low, and production operation is strong, and cause spliced hollow abrading-ball model quality
