Description
Technical field
This utility model relates to a kind of injection mold structure heated.
Background technology
The injection mold of prior art can not be heated, and especially when producing thicker light guide plate owing to needing the raw material injected more, the raw material heat radiation in mould is uneven, thus causes the light guide plate of injection corrugated or Density inhomogeneity.
Utility model content
For overcoming the deficiencies in the prior art, this utility model provides a kind of injection mold structure heated.
The technical scheme that this utility model provides is:
A kind of injection mold structure heated, including base, the first loading plate, the second loading plate, the first fixed plate, the second fixed plate, heating rod and end plate；
Described base, the first loading plate and the second loading plate are the tabular of strip；The top of described base configures described first loading plate, and the top of described first loading plate configures described second loading plate；Side on the plate face of described second loading plate configures described first fixed plate, and the opposite side on the plate face of described second loading plate configures described second fixed plate；Described first fixed plate, the second fixed plate and end plate cooperatively form a groove, and described groove is injection district；
It is positioned on described second loading plate of described bottom portion of groove and includes two separate heating rods；A heating rod is respectively included in described first fixed plate and the second fixed plate.
Preferably, described groove is rectangle, and described heating rod is strip, and the length of described heating rod is not less than the length of described groove.
Preferably, described heating rod is parallel to each other.
Preferably, a middle fixing plate is also included in described groove；Described middle fixing plate is positioned at described groove central authorities, and described groove is divided into two injection districts.
Preferably, described base, the first loading plate, the second loading plate, the first fixed plate, fixed by screw rod between the second fixed plate and end plate.
The beneficial effects of the utility model:
The injection mold structure heated of the present utility model, is heated to injection district by the heating rod in two heating rods being arranged on the second loading plate bottom injection district and the first fixed plate and the second fixed plate.When producing thicker light guide plate, by heating rod is carried out electrified regulation, the structure of mould is heated up to raw materials melt state, by heating rod power-off after injection completes, light guide plate is allowed to cool down, preventing the big rapid heat dissipation of raw material area owing to first injecting in groove, cause bottom raw material first to cool down, follow-up raw material is walked to expect the uneven corrugated caused or causes the Density inhomogeneity of light guide plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the injection mold structure heated of the present utility model；
Fig. 2 is the generalized section of the groove part of the injection mold structure heated of the present utility model；
Fig. 3 is the structural representation of the heating rod of the injection mold structure heated of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of injection mold structure heated, including base the 1, first loading plate the 2, second loading plate the 3, first fixed plate the 4, second fixed plate 5, heating rod 6 and end plate 7；
Described base the 1, first loading plate 2 and the second loading plate 3 are the tabular of strip；The top of described base 1 configures described first loading plate 2, and the top of described first loading plate 2 configures described second loading plate 3；Side on the plate face of described second loading plate 3 configures described first fixed plate 4, and the opposite side on the plate face of described second loading plate 3 configures described second fixed plate 5；Described first fixed plate the 2, second fixed plate 3 and end plate 7 cooperatively form a groove, and described groove is injection district；
It is positioned on described second loading plate 3 of described bottom portion of groove and includes two separate heating rods, the respectively first heating rod 8 and the second heating rod 9；A heating rod, the respectively the 3rd heating rod 10 and the 4th heating rod 11 is respectively included in described first fixed plate 4 and the second fixed plate 5.
Wherein, described groove is rectangle, as it is shown on figure 3, described heating rod 6 is strip, the length of described heating rod 6 is not less than the length of described groove.Heating rod is heated by described heating rod 6 by being positioned at the wire 12 of its end.When configuration, described heating rod 6 is parallel to each other, it is ensured that heated described second loading plate the 3, first fixed plate 4 is identical with the temperature of the second fixed plate 5.
A middle fixing plate 13 is also included in described groove；Described middle fixing plate 13 is positioned at described groove central authorities, and described groove is divided into two injection districts, and the respectively first injection district 14 and second is molded district 15, so, the most plastic two pieces of light guide plates of injection mold.
Fixed by screw rod between described base of the present utility model 1, first loading plate the 2, second loading plate the 3, first fixed plate the 4, second fixed plate 5 and end plate 7.
In use, first described first heating rod the 8, second heating rod the 9, the 3rd heating rod 10 and the 4th heating rod 11 is heated, second loading plate the 3, first fixed plate 4 is heated to identical with material temperature with the second fixed plate 5, or ensure the temperature that raw material is molten condition, or for ensureing that raw material will not be in the temperature of very first time cooled and solidified.It is then injected into raw material, by described heating rod power-off after raw material has injected, treats that raw material is cooled into thicker light guide plate.
