Abstract
Provided is a secondary core loosing mechanism for a faucet of a flaring bend die. The mechanism comprises a die cavity and core; a flaring bend is formed between the cavity and the core, one part of the flaring bend is a faucet part, the other part of the flaring bend is a flaring part, the inner wall of the faucet part is provided with an external connecting block which is connected with an external slide block, and the external slide block is driven by a core loosing oil cylinder to loose the core.The mechanism is characterized in that: the outer wall of the faucet part and the outer wall of the external connecting block are provided with a circular sleeve; a limit groove is fabricated in the circular sleeve; a bulge loop is fabricated on the external connecting block; the limit groove cooperates with the bulge loop. According to the invention, the integral circular sleeve is provided at the faucet part of the flaring bend, which enables a parting line not to occur after a product is molded and enables the product to have a beautiful appearance; the integral circular sleeve is sealed and is reliable during utilization; a secondary core loosing manner is used when the circular sleeve is loosed, and the circular sleeve and a slug of the faucet are loosed together under driving of a same force; the mechanism provided in the invention has the advantages of simple construction and stable and reliable motion.
Description
Technical field
The present invention relates to a kind of secondary core-pulling mechanism of flaring elbow mould inserting port, belong to the mould of plastics field.
Background technology
At present, adopt mould of plastics to produce bend with expanding hole, the die cavity of bend with expanding hole is all to be divided into two slit bamboo or chopped woods to open respectively in the cavity plate and core plate of mould, form die joint between cavity plate and core plate, have a parting line after formed product, affect the outward appearance of product, special is the faucet section of bend with expanding hole, parting line can cause sealing property to reduce, and function is used in impact.Therefore, the inventor has designed a kind of circle cover that an integral body is set outside the faucet section of product, wraps in outside the faucet section of product, avoid producing parting line after formed product, but whole round nested structure can not directly be deviate from product from mould, causes demoulding difficulty.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide the same power of a kind of employing to drive product fuse and circle cover twice core pulling, the secondary core-pulling mechanism of flaring elbow mould inserting port of avoiding product to pull.
The technical scheme of secondary core-pulling mechanism of flaring elbow mould inserting port of the present invention is: comprise mold cavity and core, the bend with expanding hole that moulding is arranged between die cavity and core, one section of bend with expanding hole is faucet section, another section is flared section, the inwall of faucet section has the socket fuse, the socket fuse has external, external connects outer slide, outer slide is driven and is loosed core by the oil cylinder of loosing core, it is characterized in that the outer wall of described faucet section and the outer wall of external are provided with the circle cover, be shaped with limited impression in circle cover, be shaped with position limiting convex ring on external, position limiting convex ring matches with limited impression.
The invention discloses a kind of secondary core-pulling mechanism of flaring elbow mould inserting port, while loosing core, at first drive die cavity and core die sinking by injection machine power, because the faucet section outer wall at bend with expanding hole is provided with the circle cover, after making formed product, faucet section does not have parting line, after die sinking, the oil cylinder of loosing core first drives outer slide and outwards slides, outer slide drives external, external drives the socket fuse and looses core, now, the circle cover is motionless, the socket fuse reduces the package power of circle cover after extracting out, fixing and the protective effect of the paired product of round casing, owing in the circle cover, being shaped with limited impression, be shaped with position limiting convex ring on external, when external skid off certain distance after (lid segment distance be the socket fuse Core-pulling distance from), position limiting convex ring contacts with limited impression, the oil cylinder of loosing core continues to loose core, pull the circle cover to extract out together, loosed core, finally by mold ejection mechanism by outside the bend with expanding hole ejection die.This programme arranges the circle cover of an integral body in the faucet section of bend with expanding hole, make to avoid producing parting line after formed product, aesthetic in appearance, during use, reliably, the circle cover adopts the twice core pulling mode in sealing, by same power, is driven and is extracted out together with the socket fuse, simple in structure, having stable behavior, reliable.
The accompanying drawing explanation
Fig. 1 is secondary core-pulling mechanism of flaring elbow mould inserting port structural representation of the present invention;
Fig. 2 is the secondary core-pulling mechanism of flaring elbow mould inserting port of the present invention view of loosing core.
The specific embodiment
The present invention relates to a kind of secondary core-pulling mechanism of flaring elbow mould inserting port, as Fig. 1, shown in Fig. 2, comprise mold cavity 1 and core 2, the bend with expanding hole 3 that moulding is arranged between die cavity 1 and core 2, one section of bend with expanding hole is faucet section 31, another section is flared section 32, the inwall of faucet section 31 has socket fuse 4, socket fuse 4 has external 41, connect outer slide 5 for external 41, outer slide 5 is driven and is loosed core by the oil cylinder 6 of loosing core, it is characterized in that the outer wall of described faucet section 31 and the outer wall of external 41 are provided with circle cover 7, be shaped with limited impression 8 in circle cover 7, be shaped with position limiting convex ring 42 on external 41, position limiting convex ring 42 matches with limited impression 8.While loosing core, at first drive die cavity 1 and core 2 die sinkings by injection machine power, because faucet section 31 outer walls at bend with expanding hole 3 are provided with circle cover 7, after making formed product, faucet section 31 does not have parting line, after die sinking, the oil cylinder 6 of loosing core first drives outer slide 5 and outwards slides, outer slide 5 drives external 41, driving socket fuse 4 for external 41 looses core, now, circle cover 7 is motionless, socket fuse 4 reduces the package power of circle cover after extracting out, circle cover 7 forms the fixing and protective effect to product, owing in circle cover 7, being shaped with limited impression 8, be shaped with position limiting convex ring 42 on external 41, when external 41 skid off certain distance after (lid segment distance be the socket fuse Core-pulling distance from), position limiting convex ring 42 contacts with limited impression 8, the oil cylinder 6 of loosing core continues to loose core, pull circle cover 7 to extract out together, loosed core, finally by mold ejection mechanism by outside the bend with expanding hole ejection die.This programme arranges the circle cover of an integral body in the faucet section of bend with expanding hole, make to avoid producing parting line after formed product, aesthetic in appearance, during use, reliably, the circle cover adopts the twice core pulling mode in sealing, by same power, is driven and is extracted out together with the socket fuse, simple in structure, having stable behavior, reliable.
