The problems such as surface defect.
In view of this, it is necessary to a kind of improved resin molding mold is designed, to solve the above problems.
The content of the invention
It can shorten the resin molding mold of injecting glue and emptying bubble time it is an object of the invention to provide a kind of.
For achieving the above object, the invention provides a kind of resin molding mold, including epimorph, positioned at described outer
Mandrel in shape mould and the cover plate being detachably connected with the epimorph, the epimorph are the tubular structure of both ends open,
The cover plate is located at the two ends of the epimorph, chamber is formed between the mandrel and the epimorph, the cover plate is provided with
The runner being connected with the chamber, the runner includes the collecting tray close to the chamber, point connected with the collecting tray
Chute and the charging aperture connected with the splitter box, the splitter box conflux including being uniformly distributed in the charging aperture with described
Multiple runners between groove.
As a further improvement on the present invention, the collecting tray is the ring for being located on the cover plate close to the chamber portion
Shape runner.
As a further improvement on the present invention, the charging aperture, the collecting tray, the mandrel and the epimorph
On the same line, and the charging aperture, the collecting tray, the cross section of the mandrel and the epimorph are center line
It is circular.
As a further improvement on the present invention, the radius of the cross section of the collecting tray is transversal not less than the charging aperture
The radius in face.
The beneficial effects of the invention are as follows：The resin molding mold of the present invention is shunted by increasing between charging aperture and chamber
Groove and collecting tray, so as to slow down the speed for the colloidal sol for flowing into chamber, while make colloidal sol uniformly flow into chamber, shorten injecting glue and
The bubble time is emptied, the small moulded products of resin homogeneous immersion, performance dispersiveness are made.

Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Refer to the structural representation of the resin molding mold of the present invention 100 shown in Fig. 1.The resin molding mold 100
Mandrel 2 including epimorph 1, in the epimorph 1, the cover plate 3 being detachably connected with the epimorph 1, by the lid
The chamber 4 and the connection cover plate 3 of plate 3, the mandrel 2 and epimorph formation and the bolt 6 of the epimorph 1 and
The nut 7 matched with the bolt 6.
In the present invention, the epimorph 1 is the tubular structure of both ends open.
The mandrel 2 be arranged with the epimorph 1 in and the mandrel 2 and the epimorph 1 are coaxial.
Fig. 2 is referred to Fig. 3 and with reference to shown in Fig. 1, the cover plate 3 is located at the two ends of the epimorph 1.The cover plate 3
Provided with the medial surface close to the chamber 4（Non- label）And the lateral surface 301 opposite with the medial surface.On the cover plate 3
The runner 5 being connected with the chamber 4 is additionally provided with, the runner 5 includes sequentially setting from the lateral surface 301 to the medial surface
The charging aperture 51 put, the splitter box 52 connected with the charging aperture 51 and the collecting tray 53 being connected with the splitter box 52.
The centre of the cover plate 3 is additionally provided with along the recessed groove 54 extended from the inner side towards the bearing of trend of collecting tray 53.
In the present invention, the charging aperture 51 is located at the centre of the cover plate 3, is preferably from the lateral surface 301
The cylindrical groove extended to the splitter box 52.
The splitter box 52 includes the multiple runners being uniformly distributed between the charging aperture 51 and the collecting tray 53,
It is preferred that, the runner 52 is the cylindrical flow extended from the charging aperture 51 to the collecting tray 53.It is arranged such,
The colloidal sol flowed into by the charging aperture 51 is shunted, the speed of colloidal sol is slow down.
The collecting tray 53 is the annular being located on the cover plate 3 extended from the runner 52 to the chamber 4
Runner, it is preferred that radius of the radius of the cross section of the collecting tray 53 not less than the cross section of the charging aperture 51.
In the present invention, the center line of the charging aperture 51, the collecting tray 53, the mandrel 2 and the epimorph 1
On the same line.
Refer to shown in Fig. 4, the two ends of the mandrel 2 are provided with connection boss 21, the connection boss 21 and the depression
Groove 54 matches.The connection boss 21 is placed in the recessed groove 54, realizes that the mandrel 2 is determined with the accurate of the cover plate 3
