Background technology
The injection moldings such as current calotte injection, bottle cap injection adopt traditional design usually, main employing angled-lift splits pulled core structure, and the slide guide form of the slide guide part of angled-lift splits mainly dovetail form, mainly there is following problem in traditional dies structure: is dovetail pointed part processing difficulties on the one hand; Dovetail and the relevant sliding assembling difficulty replaced the spare parts on the other hand; Mould structure itself is complicated, and procedure of processing is loaded down with trivial details, and die cost costly.Being buckled in when loosing core of plastic can be scraped off or be out of shape, the sealing of calotte buckle can be affected, therefore except need ensureing building core machining accuracy, the buckle ensureing the plastic when loosing core also is needed to be scraped off and to be out of shape, Here it is requires to loose core the accurate of action, and therefore the layout of mold cavity and the moulding section of installation buckle are the keys of Design of Dies.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of plastics calotte mould, the slanted pushing rod of both sides is inwardly promoted by the contact surface of insert and slanted pushing rod by this plastics calotte mould, and what solve the loaded down with trivial details and plastic of procedure of processing is buckled in the problem that can be scraped off or be out of shape when loosing core.
The utility model is achieved by the following technical programs.
A kind of plastics calotte mould that the utility model provides, comprise cover half assembly, dynamic model assembly, locating dowel, release link, ejecting mechanism, base plate and guide pillar, described dynamic model assembly is fixedly installed guide pillar, can slides in cover half 15 in the cover half that the top of guide pillar is inserted in cover half assembly; Supported by locating dowel between described base plate and dynamic model assembly, be provided with ejecting mechanism between described base plate and dynamic model assembly, described ejecting mechanism is sleeved in locating dowel by positioning sleeve, and can slide along locating dowel; It is characterized in that: the ejector beam of described ejecting mechanism and release link are fixed on seat board, described seat board is also movably installed with slanted pushing rod, the top of described slanted pushing rod and ejector beam arrives die cavity through dynamic model assembly, and described release link also can be slided through dynamic model assembly in its pilot hole; The side that insert in described dynamic model assembly contacts with slanted pushing rod becomes angle with between vertical direction.
Angle between the side that dynamic mould core in described dynamic model assembly contacts with slanted pushing rod and vertical direction is 5 ° ~ 8 °.
Seat board in described ejecting mechanism is fixedly connected with by screw with backing plate.
Lathe lift pin passageways is preset with in the middle of described base plate.
The beneficial effects of the utility model are: utilize its slanted pushing rod, in motion process, moving both vertically of mould opening and closing is changed into horizontal movement, thus ensure the appearance requirement of plastic, ensure that the buckle of the plastic when loosing core can not be scraped off and be out of shape; Namely have employed slanted pushing rod in motion process, complete inner side core-pulling and eject plastic action simultaneously, this mould features compact structure, succinct, make die worker obtain larger raising as life and reliability.
