Abstract
The utility model belongs to the technical field of moulds, and provides a tensile failure prevention product structure on a mould, comprising a female mould and a male mould which are arranged in a way of opening and closing up and down, wherein a product is arranged on the female mould; a slider is arranged between the male mould and the female mould; an inclined ejector rod which drives the slider to move is arranged on the slider; an injection molding nozzle is arranged on the male mould; a runner is arranged between the lower surface of the injection molding nozzle and the product; a condensed material is molded on the product in an injection way through the runner from the injection molding nozzle; a boss is arranged on the slider; when the mould is opened, the condensed material is blocked by the boss and the condensed material is detached from the female mould during the mould opening process, but attached on the male mould; and therefore, the tensile failure of the product is prevented from occurring. The tensile failure prevention product structure on the mold has the advantages that since the slider structure is provided with the additionally arranged boss, the phenomenon of the tensile failure of the product, caused by that the condensed material in the runner adheres to the female mould, is solved fundamentally, based on a mechanics principle; in addition, the occurrence of the tensile failure of the product is prevented from the structure when the mould is designed; and therefore, the product is unnecessarily repaired, the mould trial cost is reduced, and the product pass rate is improved.
Description
Technical field
The utility model belongs to technical field of mold, relates to the anti-product structure of breaking on a kind of mould.
Background technology
When the product injection moulding is accomplished, coagulating material and can stick at the injection nozzle on the master mold in the feature die opening procedure in the general runner, and normal state should be a product and expect that with fixed attention one is in the male model part together and is ejected by thimble; Because it is sticking with in master mold that runner coagulates material; Therefore product and runner coagulate and expect to be relative motion, and regular meeting breaks the gate area product in the die sinking motion process, and existing method only is to the polishing of runner sidewall; Require polishing technology person to move gimmick like this than standard; Though the product phenomenon effect that has some improvement is broken to sticking master mold in polishing back, but product percent of pass improved, but can not tackle the problem at its root.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art; And provide a kind of simple in structure; Improve anti-on the mould of product percent of pass and break product structure, and be support, fundamentally solve runner and coagulate the phenomenon that the sticking master mold of material is broken product with the mechanics principle.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the anti-product structure of breaking on a kind of mould, comprise master mold and male model that folding up and down is provided with, and product is arranged on the master mold; Between male model and master mold, be provided with slide block; Slide block is provided with the angle ejector rod that drives slide block movement, and described male model is provided with injection nozzle, has runner between injection nozzle lower surface and the product; Injection nozzle is expected on the product through the runner injection moulding with fixed attention; It is characterized in that: have boss on the described slide block, boss blocks and coagulates material and make and coagulate that material breaks away from master mold in the die sinking process and with being attached on the male model during die sinking, thereby avoids breaking product.
The measure of taking for the optimization such scheme specifically comprises:
Anti-breaking in the product structure on above-mentioned a kind of mould; The distance that described boss exceeds the runner upper surface is 4mm～7mm; And be shaped on boss from right to left that the degree of depth is the circular hole of 8mm～10mm, described circular hole is 0.5mm～1.5mm apart from the runner upper surface.
Anti-breaking in the product structure on above-mentioned a kind of mould, described runner sidewall is through polishing.
Compared with prior art; The advantage of the utility model is to add at slide block structure puts boss, is support with the mechanics principle, fundamentally solves runner and coagulates the phenomenon that the sticking master mold of material is broken product; The generation of when mould designs, breaking product from the structure prevention; Need not to reprocess, reduce the die trial cost, improve product percent of pass.
Description of drawings
Fig. 1 is the anti-matched moulds view of breaking product structure on this mould;
Fig. 2 is the anti-die opening state sketch map of breaking product structure on this mould.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
Among the figure, master mold 1; Male model 2; Slide block 3; Angle ejector rod 4; Injection nozzle 5; Runner 6; Expect 7 with fixed attention; Boss 8; Circular hole 9; Product 10.
As depicted in figs. 1 and 2, the anti-product structure of breaking on this mould comprises master mold 1 and male model 2 that folding up and down is provided with; Product 10 is arranged on the master mold 1; Between male model 2 and master mold 1, be provided with slide block 3, slide block 3 is provided with the angle ejector rod 4 that drives slide block 3 motions, and male model 2 is provided with injection nozzle 5; Have runner 6 between injection nozzle 5 lower surfaces and the product 10, injection nozzle 5 expects 7 to product 10 with fixed attention through runner 6 injection mouldings.
On slide block 3, has boss 8; Here to exceed the distance of runner 6 upper surfaces be 4mm～7mm to boss 8; And on boss 8, being shaped on from right to left, the degree of depth is the circular hole 9 of 8mm～10mm; Circular hole 9 is 0.5mm～1.5mm apart from runner 6 upper surfaces, and boss 8 blocks and expects that with fixed attention 7 make and expect that with fixed attention 7 break away from master mold 1 and with being attached on the male model 2 in the die sinking process during die sinking, thereby avoids breaking product 10; In order further to prevent to break product 10, described runner 6 sidewalls are through polishing.
The operation principle that anti-on this mould breaks product structure is following: angle ejector rod 4 is twitched slide blocks 3 and is slided left when die sinking, and slide block 3 is taken out out certain distance by angle ejector rod 4, but expects that with fixed attention 7 do not deviate from the circular hole 9 on the boss 8 fully on the runner 6; And pind down disengaging master mold 1 by slide block 3; Slide block 3 continues to left movement, and expect that 7 break away from the circular hole 9 on the boss 8 fully this moment with fixed attention, expects that 7 break away from master mold 1 fully thereby make with fixed attention in die sinking on the runner 6; The male model 2 of enclosing, thus avoid breaking product 10.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spiritual defined scope of the utility model.
