Abstract
The invention provides a plastic mold for an electronic pen holder. The plastic mold comprises a static template, a cavity plate and a dynamic template, wherein eight cavities, sprues communicated with the cavities and runners communicated with the sprues are formed in the cavity plate, the overall dimensions of the eight cavities are completely consistent, the eight cavities are arranged in parallel along the horizontal direction, every two cavities are taken as a unit, the two cavities in each unit are communicated with each other through the runner, the runners are communicated with the corresponding sprues, the shape of the cavities is consistent with the shape of the pen holder, sliding chutes are formed in one sides of the cavities, push rods are arranged in the sliding chutes and are opposite to the cavities, and one ends of the push rods are fixed on connecting rods which are connected with piston rods of air cylinders by driving. Through the structure that one runner corresponds to two cavities for simultaneous injection molding, glue entering the cavities is ensured to be equal, and then the air cylinders are adopted for driving the push rods to complete molding. The plastic mold is simple in structure and fast in injection molding, and can increase the yield and effectively improve the working efficiency.
Description
Technical field
The present invention relates to a kind of mould of plastics of electronic pen penholder.
Background technology
While adopting the Shooting Technique moulded plastic products, due to the mould structure factor, general being injection molded on mould the electronic pen penholder, between its cavity structure and cast gate, form complicated, make its production efficiency low, also easily occur that at the shaft of a writing brush some burrs or the shaft of a writing brush are smooth not, all easily make mould defective simultaneously, the qualification rate of its product is reduced, thereby strengthen cost.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of mould of plastics of electronic pen penholder is provided.
Purpose of the present invention is achieved through the following technical solutions:
The mould of plastics of electronic pen penholder, comprise quiet template, cavity plate and moving platen, the cast gate that cavity plate is provided with die cavity, be connected with die cavity and the runner be connected with cast gate, it is characterized in that: described cavity plate is provided with 8 die cavities, the appearance and size of 8 die cavities is in full accord, and 8 die cavity along continuous straight runs are parallel arranges side by side, and every two die cavities are a unit, two die cavities of each unit are connected by runner, and runner is connected with the corresponding cast gate that advances; The shape of described die cavity is consistent with the shape of penholder; One side of described die cavity is provided with chute, be provided with push rod on described each chute, push rod is relative with die cavity, one end of described each push rod all is fixed on connecting rod, connecting rod drives and is connected with the piston rod of cylinder, when push rod enters in die cavity by cylinder, be 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 runner is " people " font.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
The present invention comes the structure of corresponding 2 die cavities to carry out injection moulding by a runner simultaneously, the glue that assurance enters in die cavity is equal, then adopts cylinder drive push rod to complete mold, and its apparatus structure is simple, be convenient to safeguard, fast with the timer injection mo(u)lding, can improve output, effectively increase work efficiency, adopt the polishing push rod simultaneously, make it when being injection molded into mould, mould is not prone to burr and coarse phenomenon, has guaranteed the quality of the shaft of a writing brush.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: organigram of the present invention.
The specific embodiment
As shown in Figure 1, the mould of plastics of electronic pen penholder, comprise quiet template, cavity plate 1 and moving platen, the cast gate 4 that cavity plate 1 is provided with die cavity 2, be connected with die cavity 2 and the runner 5 be connected with cast gate 4, it is in full accord that cavity plate 1 is provided with the appearance and size of 2,8 die cavities 2 of 8 die cavities, 8 die cavity 2 along continuous straight runs are parallel and arrange side by side, every two die cavities 2 are a unit, and two die cavities of each unit logical 2 are crossed runner 5 and are connected, and runner 5 is connected with the corresponding cast gate that advances; The shape of die cavity 2 is consistent with the shape of penholder; One side of die cavity 2 is provided with chute, be provided with push rod 3 on each chute, push rod 3 is relative with die cavity 2, one end of each push rod 3 all is fixed on connecting rod, connecting rod drives and is connected with the piston rod of cylinder 6, when push rod 3 enters in die cavity by cylinder 6, pushes away between 3 bars and die cavity 2 and is provided with gap, gap can be injection molded into a shaft of a writing brush just, and runner 5 is " people " font.
Above-mentioned push rod 3 is after polishing, and push rod 3 smoother, when injection moulding, be difficult for allowing the shaft of a writing brush inwall burr or irregularly shaped occur, effectively guarantees the quality of its product.
When mold, cylinder 6 can operate, to drive 8 push rods 3 pushes ahead to die cavity 2, form one and be with gapped space, then by sprue, the cast gate that advances on runner 5 is carried out to injection moulding, carry out injection moulding to the push rod in die cavity 23 by the cast gate 4 be connected with bar runner 5 simultaneously, completing exhaust hood 6 in injection moulding can move by drive push rod 3 backward, push rod 3 integral body are all shifted out to die cavity 2 to chute, the mould ejection by moulding by the liftout attachment in this mould structure now, liftout attachment comprises that the integral body matched with die cavity 2 ejects core, core is located on a liftout plate, and a fore-set holds and props up liftout plate through moving platen, eject forward core by liftout plate again and by mould ejection, the core and the cavity dimension that eject use are in full accord, be easy to eject, and the surface that mould is ejected does not have any vestige that ejects, the flatness of specimen surface is good, sample mass is high.
It is emphasized that: above is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
