Abstract
The utility model discloses a light guiding plate mould with a regulating device, which comprises a mould block, two mould cavities, a master flow channel and two branch flow channels; wherein, the two mould cavities are positioned in the mould block, the two mould cavities are respectively connected with the master flow channel through the two branch flow channels, and a regulating device is connected between the two mould cavities. The novel light guiding plate mould can enable mould flow in two mould cavities of the ultra-thin light guiding plate mould to be balanced in high-speed injection process, so the optical effect of ultra-thin light guiding plate is improved, the forming cycle is shortened, and the quality and productivity are improved.
Description
Technical field
The utility model relates to the field of LGP, particularly a kind of light-conducting board mold with adjusting device.
Background technology
LGP is as the core part on the module backlight, by the Shooting Technique moulding.Along with market proposes thinner, brighter requirement to LGP, the innovation of the Shooting Technique of ultra-thin light guide board and raising are the vital tasks that industry faces.But ultra-thin light guide board often runs into the unbalanced problem of injection moulding in injection moulding process, each mould that is LGP comprises two die cavitys, can occur a die cavity in injection moulding process satiates, and another die cavity discontented situation of filling also, cause the site above the LGP variant, therefore also there is very big difference in the optical effect of the LGP of two die cavity formation.
The utility model content
The technical problems to be solved in the utility model is the defective that there are differences for the optical effect that overcomes the LGP of two die cavity formation in the prior art, a kind of light-conducting board mold with adjusting device is provided, its by an adjusting device make two die cavitys during fabrication mould stream reach balance.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of light-conducting board mold, it comprises a module, two die cavitys, a sprue and two runners, this two die cavity is positioned at this module, this two die cavity is connected with sprue by two runners respectively, it is characterized in that, connect an adjusting device between this two die cavity.
Wherein, this adjusting device comprises two control valves.
Wherein, these two control valves lay respectively on the corresponding runner.
Positive progressive effect of the present utility model is: the utility model light-conducting board mold can be so that ultra-thin light guide board mould mould stream of two die cavitys in the high speed injection motding process reaches balance, thereby improve the optical effect of ultra-thin light guide board, shorten molding cycle, improve quality and production capacity.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the A-A schematic cross-section along Fig. 1.
Fig. 3 is the preceding local enlarged diagram of the utility model adjusting device rotation.
Fig. 4 is the postrotational local enlarged diagram of the utility model adjusting device.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the light-conducting board mold of the utility model band adjusting device comprises a module 1, two die cavitys 2, an adjusting device, a sprue 4 and two runners 5, two die cavitys 2 are positioned at this module 1, two runners 5 lay respectively at the both sides of sprue 4, this two die cavity 2 is connected with sprue 4 by two runners 5 respectively, this adjusting device comprises valves such as two control valves 3 or pneumatic operated valve, two control valves 3 lay respectively on the corresponding runner 5, if rotating regulation valve 3, then the width of Dui Ying runner 5 can narrow down.
Specific operation process of the present utility model is as follows:
As shown in Figure 3, materials flow (generally being resin) can obtain the LGP product after injecting two die cavitys 2 respectively by sprue 4 and two runners 5 at last.
When the materials flow in the die cavity 2 is uneven, as shown in Figure 4, when the flow velocity of the materials flow in the die cavity 2 in left side is too fast, regulate the control valve 3 of (rotation) left side runner 5 this moment with inner hexagon spanner, along with the rotation of control valve 3, the width of left side runner 5 can narrow down, promptly among Fig. 4 the width D of runner 5 less than the width C of runner among Fig. 35, the materials flow of runner 5 in left side slows down, thereby makes the mould mobile equilibrium of two die cavitys 2.
In sum, the utility model light-conducting board mold can be so that ultra-thin light guide board mould mould stream of two die cavitys in the high speed injection motding process reaches balance, thereby improves the optical effect of ultra-thin light guide board, shortens molding cycle, improves quality and production capacity.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (3)
1, a kind of light-conducting board mold with adjusting device, it comprises a module, two die cavitys, a sprue and two runners, and this two die cavity is positioned at this module, and this two die cavity is connected with sprue by this two runner respectively, it is characterized in that, connect an adjusting device between this two die cavity.
2, the light-conducting board mold of band adjusting device as claimed in claim 1 is characterized in that, this adjusting device comprises two control valves.
