Abstract
The utility model discloses a kind of light-conducting board mold, it has symmetrically arranged upper cavity and lower mode cavity, there is in upper cavity upper mold core, there is in lower mode cavity lower mold core, be provided with between upper mold core and lower mold core into splicing block, enter splicing block and be provided with the runner mold insert connecting two core rods, the side of upper mold core and lower mold core connects side piece respectively, connection top, the top piece of upper mold core, the bottom of lower mold core connects afterbody piece, and four angles of this upper mold core and lower mold core are fillet.Four right-angle design of existing core rod become fillet by this utility model light-conducting board mold, it is to avoid the right angle of master core produces the burr spoiling angle and make light guide plate product produce.
Description
Technical field
This utility model relates to a kind of light-conducting board mold.
Background technology
As it is shown in figure 1, existing light-conducting board mold 10 ', four angles of its core rod 20 ' are right angle 201, and the side of its surrounding piece 30 ' connects at four angles of core rod 20 '.Because of surrounding piece 30 ' and be positioned at centre the splicing block 40 ' that enters connect at four angles of core rod 20 ', core rod after die assembly easily produces space at 20 ' four angles, thus it is bad to cause the product after molding easily to produce burr at four angles, and existing core rod 20 ' is right angle 201, and the most easily produce at right angle 201 and spoil angle, thus being also easily caused the product after molding, easily to produce burr at four angles bad.
In view of this, the design people designs for existing light-conducting board mold structure and does not attains perfect caused many disappearances and deeply conceive with inconvenience, and actively studies improvement and have a fling at and develop and design this utility model.
Utility model content
The purpose of this utility model is to provide a kind of light-conducting board mold reducing light guide plate product burr.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of light-conducting board mold, it has symmetrically arranged upper cavity and lower mode cavity, there is in upper cavity upper mold core, there is in lower mode cavity lower mold core, be provided with between upper mold core and lower mold core into splicing block, enter splicing block and be provided with the runner mold insert connecting two core rods, the side of upper mold core and lower mold core connects side piece respectively, connection top, the top piece of upper mold core, the bottom of lower mold core connects afterbody piece, and four angles of this upper mold core and lower mold core are fillet.
Described enter the two ends respectively corresponding upper mold core of splicing block and lower mold core lengthen toward upper mold core and lower mold core direction and extend, form outsourcing fillet and encase the fillet of upper mold core and lower mold core.
Described top piece lengthens toward upper mold core direction and extends, and forms an outsourcing fillet and encases two fillets at this upper mold core top.
Described afterbody piece lengthens toward lower mold core direction and extends, and forms an outsourcing fillet and encases two fillets bottom this lower mold core.
After using said structure, four right-angle design of existing core rod are become fillet by this utility model light-conducting board mold, the right angle avoiding master core produces the burr spoiling angle and make light guide plate product produce, this light-conducting board mold enter splicing block, four fillets of upper mold core and lower mold core are wrapped by top piece and afterbody piece, more can using original by four right angle as piece stitching portion, change the structure wrapped at the four of core rod angles by two pieces into, when making die assembly more convenient, the stitching portion of piece is not likely to produce space, greatly reduce the burr at four angles of light guide plate.

Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated.
As shown in Figures 4 to 6, this utility model light-conducting board mold has symmetrically arranged upper cavity 1 and lower mode cavity 2, there is in upper cavity 1 upper mold core 11, there is in lower mode cavity 2 lower mold core 21, it is provided with between upper mold core 11 and lower mold core 21 into splicing block 3, enter splicing block 3 and be provided with the runner mold insert 4 connecting two core rods, the side of upper mold core 11 and lower mold core 21 connects side piece 5 respectively, connection top, the top piece 6 of upper mold core 11, the bottom of lower mold core 21 connects afterbody piece 7, and four angles of this upper mold core 11 and lower mold core 21 are fillet 111,121.
In this utility model, described in enter the two ends respectively corresponding upper mold core 11 of splicing block 3 and lower mold core 21 lengthens toward upper mold core 11 and lower mold core 21 direction and extends, form outsourcing fillet 31 and encase upper mold core 11 and the fillet of lower mold core 21.
In this utility model, the both sides, one end of described top piece 6 lengthen toward upper mold core 11 direction and extend, and form outsourcing fillet and encase two fillets 61 at this upper mold core 11 top.
In this utility model, the both sides, one end of described afterbody piece 7 lengthen toward lower mold core 21 direction and extend, and form outsourcing fillet and encase two fillets 71 bottom this lower mold core 21.
Four right-angle design of existing core rod are become fillet by this utility model light-conducting board mold, the right angle avoiding master core produces the burr spoiling angle and make light guide plate product produce, four fillets of upper mold core 11 and lower mold core 21 are wrapped by enter splicing block 3, top piece 6 and the afterbody piece 7 of this light-conducting board mold, more can using original by four right angle as piece stitching portion, change the structure wrapped at the four of core rod angles by two pieces into, when making die assembly more convenient, the stitching portion of piece is not likely to produce space, greatly reduces the burr at four angles of light guide plate.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as without departing from patent category of the present utility model.
