Technical field
The present invention relates to a kind of sheet material extrusion moulding equipment, specifically refer to a kind of extrusion die of ladder type hollow sunlight board.
Background technology
Because being limited to the restriction of processing mold, trapezoidal sunlight board conventional on existing market is all entity structure, and not only consumptive material is large, cost is high, than great, most importantly plate property is not enough, there is light transmission difference, intensity is general, soundproof effect is poor defect.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of extrusion die of ladder type hollow sunlight board, its sunlight board produced is trapezoidal hollow wave-shape board, has consumptive material few, and cost is low, weigh light, the advantage that easy for installation, sealing property is strong, product strength is high, light transmission is good.
For realizing above-mentioned order, the present invention by following technical solution:
An extrusion die for ladder type hollow sunlight board, is characterized in that: mainly comprise die body, upper die lip, lower die lip and core rod, and described die body is provided with two fluid feeding mouths; Above die body, front side arranges described upper die lip, die lip insert is provided with on the downside of the front of upper die lip, upper die lip and upper die lip insert combine and and form first flow between the core rod in the middle part of die body front, the fluid feeding mouth conducting above first flow and die body; To arrange on the downside of described die body front and descend die lip, the front side top of lower die lip is provided with lower die lip insert, lower die lip insert and counterdie procheilon close and and form the second runner between core rod, the fluid feeding mouth conducting below the second runner and die body; The front-end architecture of described core rod is the wave structure of ladder type, and the corresponding surface of described upper die lip insert, lower die lip insert and core rod is also arranged to ladder type wave structure; The top of described core rod is provided with the straight guide groove of multiple connection first flow and the second runner, and end face between adjacent straight guide groove is provided with high pressure outlet air hole.
Further, the both sides of above-mentioned core rod wave structure are provided with large breach and first flow and the second runner are united two into one in this gap portions.
Further, the bottom of above-mentioned straight guide groove is the low ramp structure in height bottom, top.
Adding man-hour, material is entered by two fluid feeding mouths of die body respectively, then flow through first flow and the second runner respectively by exporting out the levels structure forming trapezoidal wave-shape board, at this, when material flow is when the top end face of core rod, because of the existence of straight guide groove, first flow will enter until form the connection rib being connected sheet material levels in groove with the material of the second runner, and because of the ejection of venthole mesohigh gas between adjacent straight guide groove, between adjacent connection rib, form cavity structure.
The sunlight board produced with upper die head is trapezoidal hollow wave-shape board, has consumptive material few, the advantage that cost is low, weigh light, product strength are high, light transmission is good.
In addition, because first flow and the second runner unite two into one in the large gap portions of core rod wave structure both sides, this structure can make the sheet material both sides processed form the hasp of entity, facilitates the Fast Installation between plate and plate to connect, effectively can promote installation strength and the connection sealing of sunlight board.

Detailed description of the invention
As Figure 1-4, a kind of extrusion die of ladder type hollow sunlight board, mainly comprises die body 1, upper die lip 2, lower die lip 3 and core rod 4.
Described die body 1 is provided with two fluid feeding mouths 11,12, and the structural design of dual channel is conducive to provide sufficient fluid, thus realizes the stability of production, guarantees to produce high-quality product.
Above shown die body 1, front side arranges described upper die lip 2, die lip insert 5 is provided with on the downside of the front of upper die lip 2, upper die lip 2 and upper die lip insert 5 combine and and form first flow 71 between the core rod 4 in the middle part of die body 1 front, fluid feeding mouth 11 conducting above first flow 71 and die body 1.
Arrange on the downside of described die body 1 front and descend die lip 3, the front side top of lower die lip 3 is provided with lower die lip insert 6, lower die lip insert 6 to be combined with lower die lip 3 and and fluid feeding mouth 12 conducting formed between core rod 4 below second runner 72, the second runner 72 and die body 1.
The front-end architecture of described core rod 4 is the wave structure 41 of ladder type, and described upper die lip insert 5, lower die lip insert 6 are also arranged respectively to ladder type wave structure 51,61 with the corresponding surface of core rod 4.
The top of described core rod 4 is provided with the straight guide groove 42 of multiple connection first flow 71 and the second runner 72, and end face between adjacent straight guide groove 42 is provided with high pressure outlet air hole 43.At this, consider the factors such as the extrusion pressure of material, the flow direction, the bottom of above straight guide groove 42 is set to the low ramp structure in height bottom, top, is communicated with to ensure that first flow 71 and the material in the second runner 72 can cross smoothly at discharging opening.
Adding man-hour, material is entered by two fluid feeding mouths 11,12 of die body 1 respectively, and then flow through first flow 71 and the second runner 72 respectively by exporting out levels 91,92 structure forming trapezoidal wave-shape board, its structure is as Fig. 5.At this, when material flow is when the top end face of core rod 4, because of the existence of straight guide groove 42, first flow 71 will enter until form the connection rib 93 being connected sheet material levels 91,92 in groove 42 with the material of the second runner 72, and because of the ejection of venthole 43 mesohigh gas between adjacent straight guide groove 42, between adjacent connection rib 93, form cavity 94 structure.
The sunlight board produced with upper die head is trapezoidal hollow wave-shape board, and its structure as shown in Figure 5, has consumptive material few, the advantage that cost is low, weigh light, light transmission are good.
At this, the both sides of upper mold core wave structure 41 are provided with large breach 42 and first flow 71 and the second runner 72 are united two into one in this gap portions, this structure can make the sheet material both sides processed form the thin hasp 95 of entity, Fast Installation between very convenient plate and plate connects, and effectively can promote installation strength and the connection sealing of sunlight board.
The above, it is only better embodiment of the present invention, not any pro forma restriction is done to invention, every according to know-why of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solution of the present invention.
