Abstract
Long and narrow piece of injection mold formula runner mechanism that moulds plastics in proper order that hides including injection mold's cover half and movable mould, has injection moulding's long and narrow shape working of plastics in cover half and the movable mould, set up the runner in the cover half, its characterized in that: the cover half in set up first runner, second runner, third runner, fourth runner and the 5th runner, the runner of hiding is connected separately respectively to 5 runners, the runner of hiding be divided into the three -section, first section be convex, convex connection of after section second section, the second section is L shape, it is divided into vertical section and horizontal section, connects the third section in one side of horizontal section, ascending thin slice shape is put for erecting to the third section, third section upper portion is linked together with the long and narrow back that appears the working of plastics.
Description
Technical field
The utility model relates to injection mold, particularly relates to injection mold long and narrow sub marine gate sequential injection mechanism.
Background technology
Plated item is important decoration parts special on automobile, comprehensively embodies the quality of outward appearance and interior trim, and therefore the quality of plated item product also requires very strict: require that the blank of electroplated is without defects such as injection moulding trace, pit, burrs on the one hand; Require that plating rear surface meets set designing requirement on the other hand.And existing electroplating plastic blank (particularly the working of plastics of thin-and-long) often causes batch to be scrapped because of the blemish such as slitter edge, weld mark, can not reach ideal expectation, have a strong impact on production efficiency, product surface also unsightly.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art, provides a kind of injection moulding trace to be positioned at the working of plastics back side, weldless trace, makes the injection mold of working of plastics good looking appearance long and narrow sub marine gate sequential injection mechanism.
The technical scheme of the utility model injection mold long and narrow sub marine gate sequential injection mechanism is: the fixed half and moving half comprising injection mold, the thin-and-long working of plastics of injection mo(u)lding is had in fixed half and moving half, in cover half, cast gate is set, it is characterized in that: the first cast gate is set in described cover half, second cast gate, 3rd cast gate, 4th cast gate and the 5th cast gate, 5 cast gates connect tunnel gate separately respectively, described tunnel gate is divided into three sections, first paragraph is circular arc, the afterbody of circular arc connects second segment, second segment is L-shaped, it is divided into vertical section and traversing section, the 3rd section is connected in the side of traversing section, 3rd section is the perpendicular slice-shaped put upwards, 3rd section of top is connected with the back side of thin-and-long working of plastics.
The utility model discloses a kind of injection mold long and narrow sub marine gate sequential injection mechanism, main feature is in cover half, arrange 5 cast gates, spacing between each cast gate is consistent, and each cast gate connects tunnel gate separately, the plastics first heat melted when injection moulding inject from the 3rd middle cast gate, when the plastics that heat is melted flow to the second adjacent cast gate and the 4th gate location to die cavity both sides, second, 4th cast gate carries out injection moulding again, when the plastic flow that heat is melted is to left and right when outermost first cast gate and the 5th gate location, first, 5th cast gate carries out injection moulding, utilize five cast gates sequential injection successively, effectively can eliminate the shrink mark of thin-and-long plastic part surface, the defects such as cold burden spot, and adopt each cast gate to connect tunnel gate respectively, tunnel gate is divided into the form of three sections, slitter edge is made to be hidden in the back side (fitting surface) of working of plastics, thus make the working of plastics good looking appearance of whole thin-and-long, reach ideal expectation, ensure that production efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of injection mold long and narrow sub marine gate sequential injection mechanism;
Fig. 2 is the close-up schematic view of tunnel gate and thin-and-long working of plastics mated condition.
Detailed description of the invention
The utility model relates to a kind of injection mold long and narrow sub marine gate sequential injection mechanism, as shown in Fig. 1-Fig. 2, comprise the fixed half and moving half of injection mold, the thin-and-long working of plastics 1 of injection mo(u)lding is had in fixed half and moving half, in cover half, cast gate is set, it is characterized in that: the first cast gate 2 is set in described cover half, second cast gate 3, 3rd cast gate 4, 4th cast gate 5 and the 5th cast gate 6, 5 cast gates connect tunnel gate separately respectively, described tunnel gate is divided into three sections, first paragraph 7 is circular arc, the afterbody of circular arc connects second segment 8, second segment is L-shaped, it is divided into vertical section and traversing section, the 3rd section 9 is connected in the side of traversing section, 3rd section is the perpendicular slice-shaped put upwards, 3rd section of top is connected with the back side of thin-and-long working of plastics 1.Main feature is in cover half, arrange 5 cast gates, spacing between each cast gate is consistent, and each cast gate connects tunnel gate separately, the plastics first heat melted when injection moulding inject from the 3rd middle cast gate 4, when the plastics that heat is melted flow to the second adjacent cast gate 3 and the 4th cast gate 5 position to die cavity both sides, second, 4th cast gate carries out injection moulding again, when the plastic flow that heat is melted is to left and right when outermost first cast gate 2 and the 5th cast gate 6 position, first, 5th cast gate carries out injection moulding, utilize five cast gates sequential injection successively, effectively can eliminate the shrink mark on thin-and-long working of plastics 1 surface, the defects such as cold burden spot, and adopt each cast gate to connect tunnel gate respectively, tunnel gate is divided into the form of three sections, slitter edge is made to be hidden in the back side (fitting surface) of working of plastics, thus make working of plastics 1 good looking appearance of whole thin-and-long, reach ideal expectation, ensure that production efficiency.
