Description
Technical field
The present invention relates to the mould of plastics of a kind of electronic pen penholder.
Background technology
When adopting Shooting Technique moulded plastic products, due to mould structure factor, general electronic pen penholder is injection molded on mould, complexity is constituted between its cavity structure and cast gate, make its production efficiency low, be also easy to occur that some burrs or the shaft of a writing brush are smooth not at the shaft of a writing brush simultaneously, all easily make mould defective, the qualification rate making its product reduces, thus strengthening cost.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that the mould of plastics of a kind of electronic pen penholder.
The purpose of the present invention is achieved through the following technical solutions:
The mould of plastics of electronic pen penholder, including quiet template, cavity plate and moving platen, cavity plate is provided with the cast gate that die cavity is connected and the sub-runner being connected with cast gate with die cavity, it is characterized in that: described cavity plate is provided with 8 die cavities, the overall dimensions of 8 die cavities is completely the same, 8 die cavity arrangements in parallel side-by-side in the horizontal direction, and each two die cavity is a unit, two die cavities of each unit are connected by sub-runner, and sub-runner is connected with the corresponding cast gate that enters；The shape of described die cavity is consistent with the shape of penholder；The side of described die cavity is provided with chute, described each chute is provided with push rod, push rod is relative with die cavity, one end of described each push rod is each attached on connecting rod, connecting rod drives with the piston rod of cylinder and is connected, when push rod is entered in die cavity by cylinder, being provided with gap between push rod and die cavity, the lucky injection moulding in gap is a shaft of a writing brush.
Further, the plastic test sample mold of above-mentioned electronic pen penholder, described sub-runner is " people " font.
The substantive distinguishing features of technical solution of the present invention and progress are mainly reflected in:
The structure that the present invention carrys out corresponding 2 die cavities by a sub-runner carries out injection moulding simultaneously, ensureing that the glue entered in die cavity is equal, then adopt cylinder to drive push rod to complete mold, its apparatus structure is simple, it is easy to safeguard, fast with timer injection mo(u)lding, yield can be improve, be effectively improved work efficiency, adopt polishing push rod simultaneously, making it when being injection molded into mould, mould not easily occurs with jagged and coarse phenomenon, it is ensured that the quality of the shaft of a writing brush.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: the organigram of the present invention.
Detailed description of the invention
As shown in Figure 1, the mould of plastics of electronic pen penholder, including quiet template, cavity plate 1 and moving platen, cavity plate 1 is provided with the cast gate 4 that die cavity 2 is connected and the sub-runner 5 being connected with cast gate 4 with die cavity 2, and the overall dimensions that cavity plate 1 is provided with 2,8 die cavities 2 of 8 die cavities is completely the same, 8 die cavity 2 arrangements in parallel side-by-side in the horizontal direction, each two die cavity 2 is a unit, and two die cavities of each unit logical 2 are crossed sub-runner 5 and are connected, and sub-runner 5 is connected with the corresponding cast gate that enters；The shape of die cavity 2 is consistent with the shape of penholder；The side of die cavity 2 is provided with chute, each chute is provided with push rod 3, push rod 3 is relative with die cavity 2, one end of each push rod 3 is each attached on connecting rod, connecting rod drives with the piston rod of cylinder 6 and is connected, and when push rod 3 is entered in die cavity by cylinder 6, pushes away and is provided with gap between 3 bars and die cavity 2, gap can be injection molded into a shaft of a writing brush just, and sub-runner 5 is in " people " font.
Above-mentioned push rod 3 through polishing after, push rod 3 smoother, when injection moulding, not easily allow the shaft of a writing brush inwall burr occur or irregularly shaped, be effectively ensured the quality of its product.
When mold, cylinder 6 can operate, push ahead driving 8 push rods 3 to die cavity 2, formation one is with the space in gap, then pass through sprue and the cast gate that enters on sub-runner 5 is carried out injection moulding, carry out injection moulding to the push rod 3 in die cavity 2 by the cast gate 4 being connected with bar sub-runner 5 simultaneously, completing exhaust hood 6 in injection moulding can drive push rod 3 to be moved rearwards by, push rod 3 entirety is all removed on die cavity 2 to chute, now by the liftout attachment in this mould structure by the mould ejection of molding, the entirety that liftout attachment includes matching with die cavity 2 ejects core, core is located on a liftout plate, and a fore-set holds through moving platen and props up liftout plate, core is ejected forward again and by mould ejection by liftout plate, the core ejected is completely the same with cavity dimension, it is prone to eject, and the surface that is ejected of mould does not have and any ejects vestige, the flatness of specimen surface is good, sample mass is high.
It is emphasized that: be only presently preferred embodiments of the present invention above, not the present invention is done any pro forma restriction, every any simple modification, equivalent variations and modification above example made according to the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
