Abstract

The utility model discloses a de-molding mechanism for a thimble pushed product. A fixed die base plate (1) and a sprue bush (9) are in clearance fit; a positioning ring (18) is fastened on the fixed die base plate (1); a guide sleeve (2) and a fixed die (4) are in slide clearance fit; a moveable die plate (5) and a guide post (3) are in clearance fit; a molding core (17) is arranged in a step hole of the moveable die plate (5); the moveable die plate (5), a supporting plate (6), a cushion block (7) and a moveable die base plate (10) are fixedly connected together through screws, a push plate guide post (14) is arranged the moveable die base plate (10) and is glidingly matched with a push plate guide sleeve (15); a thimble (16), a material pulling rod (13) and a reset rod (11) are arranged on a thimble fixing plate (8) and are compressed by a push plate (9); and a supporting screw (12) is locked on the moveable die base plate (10). When the product is pushed out, the thimble (16) pushes the product out of a male die.

Description

A kind of mold mechanism of thimble pushing out product
Technical field
The present invention relates to injecting molding die and die-casting forming die, is a kind of mold mechanism of thimble pushing out product.
Background technology
Metal crimp mold and injection molding all must make goods from mold cavity or core is deviate from each circulation of moulding by casting, this mechanism of deviating from goods is called ejecting mechanism in the mould.The classification of ejecting mechanism: A divides by type of drive: (1) is ejecting mechanism manually, and it is to release product by the manually-operated ejecting mechanism after die sinking.(2) motor-driven ejecting mechanism, it is to utilize the mechanism of injector or die casting machine die sinking action drives mould to release product.(3) hydraulic pressure or air pressure ejecting mechanism, it is to rely on the dedicated hydraulic or the pneumatic means that are arranged on injector or the die casting machine to make product release or blow out.B divides by the type of releasing part: (1) ejector sleeve ejecting mechanism, (2) push piece plate ejecting mechanism, (3) pushing block ejecting mechanism, (4) associating ejecting mechanism.C divides by the architectural feature of mould: (1) simple ejecting mechanism, (2) secondary ejecting mechanism, (3) two ejecting mechanisms, the ejecting mechanism of (4) threaded product, the solidifying material of (5) running gate system ejecting mechanism.Above-mentioned each ejecting mechanism reliable in structure, pressure transmits, and automaticity is high.But in actual production was made, particularly when the release of large moldeed depth chamber product, the damage of mould was very big, and mould structure is complicated again, brings very big inconvenience for the production line mold repair, if a damage parts just causes the whole series or monoblock part again to make.The position freedom that part is set on the other hand is less, and release weak effect, product very easily are out of shape, damage, and the product outward appearance is very poor.After releasing on the one hand part again and releasing product, owing to be subjected to die location by the certainly less impact of degree, resetting-mechanism is difficult to arrange, therefore cause reset bad, mold damage groundwork part.In order to overcome the deficiency of above-mentioned mould pushing-off mechanism, I am in conjunction with the experience that manufactures and designs of foreign enterprise for many years, and the spy provides following a kind of mould pushing-off mechanism, for industry personnel's reference.
Summary of the invention
The present invention provides a kind of mold mechanism of thimble pushing out product.It is achieved in that as shown in the figure ejecting mechanism is comprised of push rod, sprue puller, thimble, fixed head, push pedal, push pedal guide pillar, guide pin bushing and release link.During die sinking, dynamic model partly is moved to the left, behind die sinking one segment distance, after the push rod contact mould ejection plate of injector or die casting machine, push rod, sprue puller and ejector pin retaining plate, push pedal is transfixion all, when dynamic model partly continued to be moved to the left, product was just released from punch by push rod.A kind of mold mechanism of thimble pushing out product, it is characterized in that: top clamping plate (1) and sprue bush (19) matched in clearance, centring ring (18) is fastened on the top clamping plate (1), guide pin bushing (2) cooperates with cover half (4) glade plane space, moving platen (5) and guide pillar (3) matched in clearance, core (17) is installed in the stepped hole of moving platen (5), moving platen (5), support plate (6), cushion block (7), Bottom clamp plate (10) connects as one with screw fastening, push pedal guide pillar (14) is installed on the Bottom clamp plate (10), and become to be slidingly matched with ejector guide pillar (15), thimble (16), sprue puller (13), release link (11) is installed on the thimble fixed head (8), use push pedal (9) to compress, supporting nail (12) tightly is locked on the Bottom clamp plate (10) again.A kind of mold mechanism of thimble pushing out product, it has solved large moldeed depth chamber product when releasing, the mould damage is large, the problem of mould structure complexity and mold repair inconvenience, the free degree is less when having solved the position that part is set, and releases that weak effect, product are yielding, damage, the poor problem of product presentation quality.Solution resets difficult, the problem of mold damage groundwork part.

The specific embodiment:
A kind of mold mechanism of thimble pushing out product.Shown in the figure, ejecting mechanism is comprised of thimble (16), sprue puller (13), thimble fixed head (8), push pedal (9), push pedal guide pillar (14), ejector guide pillar (15) and release link (11).During die sinking, dynamic model partly is moved to the left, behind die sinking one segment distance, after the push rod contact mould ejection plate (9) of injector or die casting machine, thimble (16), sprue puller (13) and thimble fixed head (8), push pedal (9) is transfixion all, when dynamic model partly continued to be moved to the left, product was just released from punch by thimble.During matched moulds, utilize release link (11) that ejecting mechanism is returned to and release front state, as shown in Figure 2.
