Abstract
The utility model discloses a backoff forming demoulding device of an injection mould. The device comprises a core plate, a cavity insert and a cavity plate which are detachably arranged on the core plate, and a panel on the cavity plate, wherein a check block which downwards penetrates through the cavity plate is arranged on the panel, and an inclined chute is formed in the check block; a sliding block is arranged on the chute of the check block, and a guide rail matched with the chute is arranged on the sliding block; a pressing block of the sliding block is arranged above the sliding block, and a backoff forming insert is fixed below the sliding block; and when the check block ascends, the sliding block horizontally moves under the side pressing of the guide rail of the sliding block, and the backoff forming insert is driven to be separated from an injection molding backoff part. A mould of the device has a relatively small size, so that the utilization rate of a space is increased; and the device is reasonable in structural design, simple to design and produce, convenient to assemble and operate, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of injection mold, relates in particular to the back-off shaping stripper apparatus of this mould.
Background technology
Existing plastic electronic product industry is provided with back-off structure such as the plastic casing of remembering products such as this computer, digital camera, projecting apparatus, printer on plastic casing, back-off can make the working of plastics of separation link together by modes such as clamping, tensionings.Produce the especially special back-off of back-off corresponding die cavity and corresponding special back-off shaping stripper apparatus need be set on injection mold.Existing back-off shaping stripper apparatus mainly comprises slide block, slide block briquetting, oblique contract, mother module core, caster, Angle Pin, Angle Pin briquetting and panel.Operation principle is that make-up machine drives panel and drives Angle Pin and tiltedly contract motion vertically upward together, and the motion vertically upward of Angle Pin makes slide block that level movement tendency to the right be arranged.The spring that is in compressive state will promote the slide block level and slide to the right, thereby separate with the product back-off, make plastic cement products break away from from mother module core smoothly, and manipulator just takes out product fast from mould then.Application number provides product back-off releasing mechanism for 201120167120.2 Chinese utility model patent, comprise the master mold and the male model that are oppositely arranged up and down, male model is provided with slide block, on slide block, offer inclined hole, be fixed with Angle Pin and block on the described master mold respectively, Angle Pin is inserted in the inclined hole, and the block retaining is in a side of slide block, on slide block, be connected with sedimentation structure and deviate from structure respectively, thereby slide block drives the sedimentation structure respectively and deviates from structure motion the product back-off is broken away from.Defectives such as above technology is anti-all to exist the design processed complex, and the production cost height assembles difficulty, and the die space that takies is very big.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, the back-off shaping stripper apparatus of the injection mold that volume is less.
For achieving the above object, the technical scheme that the utility model adopted is: the back-off shaping stripper apparatus of injection mold, comprise the male model plate, be removably disposed in mother module core, caster on the male model plate, and the panel on the caster, described panel is provided with the block that is passed down through caster, and described block is provided with the chute of inclination; The chute place of described block is provided with slide block, and slide block is provided with the guide rail with described chute coupling; The slide block top is provided with the slide block briquetting, and the below is fixed with back-off shaping mold insert; Block rises, and because of the side direction compressing of block guide rail, the slide block horizontal movement drives back-off shaping mold insert and breaks away from the injection moulding fastener.The panel rising drives block and moves upward, chute on the block upper rail compressing slide block, the slide block horizontal movement, drive the motion of fastener shaping mold insert, break away from injection moulding back-off spare, briquetting can guarantee that slide block can only horizontal movement, the also horizontal movement of corresponding fastener shaping mold insert, and detach procedure can not cause damage to injection moulding back-off spare.
Described chute is a T shape chute, and described guide rail is a T shape guide rail.T shape chute cooperates with T shape guide rail, and the block uphill process is more powerful to the slide block horizontal applied force.
Described briquetting is fixed on the mother module core.The restriction slide block is along the apparent motion of mother module core.
Described slide block and guide rail opposite end are provided with shrinkage pool, are provided with spring in the shrinkage pool.In slide block, spring provides horizontal thrust to spring at the block effect of increasing, makes knockout course more smooth.
The utility model mould volume is less relatively, has promoted space availability ratio; Structural design is more reasonable, and design is produced more simple, and assembly manipulation is easy, and production efficiency greatly improves.
Description of drawings
Fig. 1 is the back-off shaping stripper apparatus structural representation of the utility model injection mold.
Fig. 2 is the back-off shaping stripper apparatus F-F place planing surface structural representation of the utility model injection mold.
The specific embodiment
Below in conjunction with Figure of description the utility model is made concrete elaboration.
As depicted in figs. 1 and 2, the back-off shaping stripper apparatus of injection mold, comprise male model plate 9, be removably disposed in mother module core 4, caster 5 on the male model plate 9, and the panel on the caster 56,6 usefulness block bolts 61 are fixed a block 3 that passes caster 5 downwards on the described panel, described block 3 is provided with the chute 301 of the T shape shape of inclination, chute 301 places of described block 3 are provided with slide block 1, and slide block 1 is provided with the guide rail 101 of the T shape shape of mating with described T shape shape chute 301; There is slide block briquetting 2 slide block 1 top, and for being fixed on the mother module core 4 with briquetting bolt 21, slide block 1 below is with assisting part bolt 12 back-off shaping mold inserts 11; Slide block 1 is provided with shrinkage pool 102 with guide rail 101 opposite ends, is provided with spring 9 in the shrinkage pool 102.Block 1 rises, and because of the side direction compressing of block 3 upper rails 301, slide block 1 horizontal movement drives back-off shaping mold insert 11 and breaks away from injection moulding fastener 8.Block 3 rises, and because of the side direction compressing of slide block guide rail 301, slide block 1 horizontal movement drives back-off shaping mold insert 11 and breaks away from injection moulding back-off spare 8, and the elastic force of the spring 9 in this process in the shrinkage pool 102 promotes slide block 1 motion; Briquetting 2 can guarantee sliding 1 can only horizontal movement, corresponding fastener shaping mold insert 11 also horizontal movements, detach procedure can not cause damage to injection moulding back-off spare 8.
