Abstract
The utility model relates to a novel type pinpoint rubber feeding flow channel structure, which is suitable for a die structure. The die structure comprises a female die cavity, the flow channel is arranged in the female die cavity, wherein, a contraction part is arranged at the bottom end of the flow channel, the contraction part comprises a circular arc part positioned at the top of the contraction part and bent to the bottom end of the flow channel; a convex part connected with the circular arc part, wherein a flow channel opening is arranged at the bottom end of the convex part, the cross section of the convex cross part is inverted trapezoid, and the two hypotenuses of the inverted trapezium are intercrossed with the surface of the circular arc part. When die sinking is performed in such a way, the stress points of the rubber material are relatively centralized, thus no residual stock exists at the feeding points of the product, subsequent processing to the product is not required to be performed, and therefore, the production efficiency is improved and the cost is saved.
Description
[technical field]
The utility model relates to mould applications, the particularly a kind of pin point glue inlet flow passage structure that can effectively mold runner mouth clout be broken fully.
[background technology]
Mould structure must enter the solation road junction to it and be optimized design, otherwise easily cause product charging place stub bar not broken fully when die sinking, thereby influence the aesthetic measure of product surface when design, must carry out following process to product.
As shown in Figure 1, be existing mold pin point glue inlet flow passage structure schematic diagram; Product 13 is between male model benevolence 11 and mother module core 12, runner 14 is located in the mother module core 12, charging when this runner 14 advances glue in order to pin mark is injected in the die cavity, this runner 14 is a serrated end 15 near runner mouth 16 1 ends, this serrated end 15 is down trapezoidal shape, this falls trapezoidal bottom and is runner mouth 16, and this falls trapezoidal two hypotenuse tops and is the circular arc bending, and this two hypotenuse and this arc bend pars convoluta are tangent.So carry out pin mark when advancing glue, sizing material is injected in the die cavity by runner 14, can finish the forming process to product after the cooling.
Yet during the die sinking of cooling back, this kind flow passage structure easily causes leaving above the product clout.See also Figure 1 and Figure 2, wherein Fig. 2 is the product schematic diagram that leaves clout; Be feed points 17 with runner mouth 16 correspondence positions on this product 13, behind product 13 cooling formings, need carry out die sinking and eject this product 13, be connected by sizing material with feed points 17 places owing to runner mouth 16 during die sinking, and serrated end 15 is longer, the sizing material stress point is unfixing when breaking, thereby easily causes sizing material not broken fully, and clout 18 stays on feed points 17.Need carry out subsequent treatment this moment to the clout 18 at feed points 17 places, and therefore this processing procedure has improved the cost of whole forming process, and influenced the aesthetic measure of product by manually finishing.
[summary of the invention]
In view of this, the utility model provides a kind of novel pin point glue inlet flow passage structure, easily makes product feed points place leave the defective of clout to overcome prior art.
For reaching above-mentioned purpose, the novel pin point glue inlet flow passage structure that the utility model provides, be applicable in the mould structure, this mould structure comprises a mother module core, described runner is located in this mother module core, and wherein this runner bottom is provided with a contraction flow region, and this contraction flow region comprises: an arc sections, this arc sections is positioned at this contraction flow region top, and this arc sections is to the bending of runner bottom; One protuberance, this protuberance is connected with arc sections, and the protuberance bottom is the runner mouth, and this protuberance cross section is trapezoidal, and this falls trapezoidal two hypotenuses and cuts mutually with this arc sections surface.
Compared to prior art, the pin point glue inlet flow passage structure that the utility model provides, owing to shortened the length of whole contraction flow region, so the sizing material stress point is comparatively concentrated when die sinking, thereby make product feed points place's noresidue clout, need not product is carried out following process, thereby enhance productivity and save cost.

[specific embodiment]
For structure of the present utility model and technical characterictic are had further understanding, be elaborated below in conjunction with accompanying drawing:
As shown in Figure 3, advance the plastic structure schematic diagram for pin mark provided by the utility model; The pin point glue inlet flow passage structure that the utility model provides, be applicable in the mould structure, this mould structure is one or three template dies in the present embodiment, and this mould structure comprises a male model benevolence 21 and a mother module core 22, in the die cavity (not shown) of product 23 between male model benevolence 21 and mother module core 22; Runner 24 is located in the mother module core 21, and wherein these runner 24 bottoms are provided with a contraction flow region 25, and this contraction flow region 25 comprises: an arc sections 26, this arc sections 26 are positioned at this contraction flow region 25 tops, and this arc sections 26 is to the bending of runner bottom; One protuberance 27, this protuberance 27 is connected with arc sections 26, and these protuberance 27 cross sections are trapezoidal, and this falls trapezoidal two hypotenuses and cut mutually with arc sections 26 surfaces, and these protuberance 27 bottoms are runner mouth 28, and this runner mouth 28 joins with feed points 29 on the product 23.
In the present embodiment, the diameter of this runner mouth 28 is 1.20mm, and these arc sections 26 radiuses are 1.25mm, and the centre point of this arc sections 26 is 2.25mm to the distance of runner mouth 28, and in actual applications, this distance can be between 1.75mm between 2.25mm; In the present embodiment, it is 35 degree that the angle of trapezoidal two hypotenuses is fallen in the cross section of described protuberance 27, and this angle can be between 30 degree and 60 degree in the practical application.
As shown in Figure 4, advance glue effect schematic diagram for this novel pin point glue inlet flow passage structure; Cut mutually with arc sections 26 surfaces owing to falling of protuberance 27 is trapezoidal, compare, shortened the length of whole contraction flow region 27 with the tangent of prior art, so when die sinking, the sizing material institute tension at runner mouth 28 places can be broken fully for comparatively concentrated, feed points 29 places noresidue clout.
This novel pin mark influent stream road plastic structure is applicable to all three template die flow passage structures, only needs as the case may be above data to be done suitable adjusting when specifically using and gets final product, and repeats no more herein.
Compared to prior art, novel pin mark provided by the present invention advances plastic structure so that product feed points place does not have Residual clout, thus the following process program removed from, thus escapable cost and enhancing productivity, and make product The aesthetic measure of product is guaranteed.
