Abstract

The utility model discloses a slider first-back type injection mould. The slider first-back type injection mould comprises a panel, a plate A, a plate B and a bottom plate which are connected in sequence, wherein a mould core is arranged between the plate A and the plate B, a mould cavity is formed in the mould core, and a slider corresponding to the mould cavity is also arranged between the plate A and the plate B; the slider first-back type injection mould further comprises an oblique guide pillar which sequentially penetrates through the plate A, the slider and the plate B, clamp slots which are symmetrical are formed in the oblique guide pillar axially, and the slider is arranged on the oblique guide pillar through matching pins with the clamp slots. The clamp slots are symmetrically formed in the two side surfaces of the oblique guide pillar axially, the pins are arranged in the sliders of the corresponding clamp slots, so that the sliders can be pushed back along the oblique guide pillar, then metal parts can be put in, the long and fine parts of the metal parts are tightly attached onto the sliders without bending due to gravity, finally the injection production is stable, and the metal parts and plastics are well fused together.

Description

Slide block first returns formula injection mould

Technical field

The utility model relates to a kind of slide block and first returns formula injection mould, for the injection mo(u)lding with metal insert plastic cement products.

Background technology

As shown in Figure 1, when plastic cement 11 is interior, need to embed metalwork 12 and when injection moulding process is realized this step, the location of metalwork 12 is particularly important.Cause cannot be normally along the plastic cement 11 and the metalwork 12 that eject the direction demoulding, need to use the first side core-pulling of common slide block to eject again, the general vertical injection molding machine that adopts is stable to guarantee the placement of metalwork 12, and its injection moulding process is: complete → die sinking of injection moulding → eject → get product → eject start → injection moulding of return → placement metalwork 12 → matched moulds → injection moulding to complete.When metalwork 12 is long, when thin, before matched moulds, metalwork 12 is placed into die, and the long and thin metal of this part is easily because gravity is bent downwardly, and when matched moulds, slide block is pushed ahead bending metal part is damaged by pressure, thereby easily causes mould to damage.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of slide block first to return formula injection mould, to realize the return in advance of injection moulding front-slider, causes mould to damage to avoid the bending of long and thin metal part.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of slide block first returns formula injection mould, comprises the panel, A plate, B plate and the base plate that connect successively, between described A plate and B plate, is provided with die, in described die, has die cavity, is also provided with the slide block of corresponding described die cavity between described A plate and B plate; Also comprise the Angle Pin through described A plate, slide block and B plate successively,

Described Angle Pin offers symmetrical draw-in groove vertically, and described slide block was arranged on described Angle Pin by pin and coordinating of described draw-in groove.

Preferably, between described slide block and B plate, be provided with wearing plate, and described slide block is fixed by press strip and described die.

Preferably, described pin one end is fastened in described draw-in groove, and the other end is provided with spring, and compresses described spring by pressing plate.

Pass through technique scheme, the slide block that the utility model provides first returns formula injection mould, slide block is fixed and is led by press strip and wearing plate, Angle Pin is as loosing core Mechanical Driven offer draw-in groove in symmetrical vertically two sides, in the slide block of corresponding draw-in groove, pin is set, pin back side pad spring so that pin can stretch, before the long and thin metalwork of placement, need utilize pin and coordinating of draw-in groove that slide block is first pushed back along Angle Pin, driving force can be machinery or artificial, then put into metalwork, long and the thin part of metalwork just tightly be attached on slide block and can be because of gravity-bending, final injection moulding is produced stable, metalwork and plastic cement can be good at merging.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Referring to figs. 1 to 3, the slide block that the utility model provides first returns formula injection mould, comprise the panel 21, A plate 22, B plate 23 and the base plate 24 that connect successively, between A plate 22 and B plate 23, be provided with die 25, in die 25, there is die cavity, finally in die cavity form the product that plastic cement 11 and metalwork 12 form, between A plate 22 and B plate 23, be also provided with the slide block 26 of corresponding die cavity; Also comprise the Angle Pin 27 through A plate 22, slide block 26 and B plate 23 successively, Angle Pin 27 offers symmetrical draw-in groove 24 vertically, and slide block 26 was arranged on Angle Pin 27 by pin 31 and coordinating of draw-in groove 24; Wherein, between slide block 26 and B plate 23, be provided with wearing plate 29, and slide block 26 is fixing with die 25 by press strip 28; Pin 31 one end are fastened in draw-in groove 24, and the other end is provided with spring 32, and by pressing plate 33 holddown springs 32.

The slide block that the utility model provides first returns formula injection mould, slide block 26 is by press strip 28 and wearing plate 29 is fixing and guiding, Angle Pin 27 is as loosing core Mechanical Driven offer draw-in groove 24 in symmetrical vertically two sides, in the slide block 26 of corresponding draw-in groove 24, pin 31 is set, pin 31 back side pad springs 32 so that pin 31 can stretch, before the long and thin metalwork 12 of placement, need utilize pin 31 and coordinating of draw-in groove 24 that slide block 26 is first pushed back along Angle Pin 27, driving force can be machinery or artificial, then put into metalwork 12, long and the thin part of metalwork 12 just tightly be attached on slide block 26 and can be because of gravity-bending, final injection moulding is produced stable, metalwork 12 can be good at merging with plastic cement 11.
