In the utility model, a plurality of common ox horn sprues in the prior art are combined into a large-flow ox horn sprue, so that the injection pressure is reduced during injection molding production, and the injection molding cost is saved; and a gap is reserved between the glue inlets, the gap between the glue inlets is within the range of 3mm-5mm, and a welding line cannot be generated between the pouring gates, so that the product appearance is improved, and the runner glue is also saved.
Description
Technical Field
The utility model relates to an injection mold technical field, in particular to solve medium-sized product weld line and advance gluey runner form structure.
Background
The sprue is the key part of the injection mold pouring system and is a feed inlet for injecting molten plastic into the cavity through the main runner and the sub-runner to form a plastic product. Whether the position, the shape and the size of the sprue are reasonable or not directly determines the quality, the injection molding effect and the efficiency of a plastic part product, and particularly for the plastic part product with high appearance quality requirement, the practice finds that: the direct gluey structure of watering that advances of traditional flip-chip mould hot runner often causes the part surface of moulding plastics to produce scalds (sun circle), gas marks etc. and mould plastics the defect, makes the defective rate of moulding the part product high enough, directly leads to moulding the manufacturing cost of part product and is difficult to reduce. The glue structure is advanced to current ordinary large-traffic formula ox horn, and the mould can adopt a plurality of ox horn formula runner products can produce the weld line defect and influence the outward appearance usually, specifically can leave shorter melt-joint line in the centre of runner interval on the product when the pouring, influences product appearance, extravagant runner defects such as sizing material when moulding plastics.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve prior art's problem, provide a solve medium-sized product weld line and advance gluey runner form structure, put a plurality of solitary ordinary ox horn formula runners together, the effectual weld line defect of avoiding influences the outward appearance, very big improvement the aesthetic property of product yields and outward appearance.
The specific technical scheme is as follows: the utility model provides a solve medium-sized product weld line and advance gluey runner form structure, is including large-traffic ox horn runner, runner mold insert, the mouth of advancing gluey of large-traffic ox horn runner leaves the interval each other, the runner mold insert is including mold insert one, mold insert two, the two corresponding positions of mold insert one, mold insert are equipped with the screw hole, lock large-traffic ox horn runner in the runner mold insert through the screw.
According to a further technical scheme, the interval between the glue inlets is within the range of 3mm-5 mm.
According to a further technical scheme, the large-flow horn gate is communicated with a hot runner.
According to a further technical scheme, the glue inlet is in a claw shape.
The technical effects of the utility model: a plurality of common ox horn gates in the prior art are combined into a large-flow ox horn gate, so that the injection pressure is reduced during injection molding production, and the injection molding cost is saved; and a gap is reserved between the glue inlets, the gap between the glue inlets is within the range of 3mm-5mm, and a welding line cannot be generated between the pouring gates, so that the product appearance is improved, and the runner glue is also saved.

Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1-5, the gate structure for solving the problem of glue inlet of the welding line of the medium product in the embodiment includes a large-flow ox horn gate 1 and a gate insert 7, wherein a gap is left between glue inlets 1-1 of the large-flow ox horn gate 1, the gate insert 7 includes a first insert 3 and a second insert 4, threaded holes are formed in corresponding positions of the first insert 3 and the second insert 4, and the large-flow ox horn gate 1 is locked in the gate insert 7 through screws 2.
In the utility model, the interval between the glue inlets 1-1 is within the range of 3mm-5 mm.
The utility model discloses in, large-traffic ox horn runner 1 and hot runner 6 put through mutually.
In the utility model, the glue inlet 1-1 is claw-shaped.
Referring to fig. 6, the common horn gate 8 in the prior art is divided into a plurality of gates, and the design has the defect that the flow rate carried by a single common horn gate is limited, so that the injection pressure is increased during injection molding, and a short fusion line 9 is left in the middle of the gate interval on a product 5 during pouring, so that the appearance of the product is affected. The utility model combines a plurality of common ox horn sprues into a large-flow ox horn sprue, and the injection pressure is reduced during injection molding production, thereby saving the injection molding cost; and a gap is reserved between the glue inlets, the gap between the glue inlets is within the range of 3mm-5mm, and a welding line cannot be generated between the pouring gates, so that the product appearance is improved, and the runner glue is also saved.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
