Abstract
The utility model relates to a timing loading plastic zipper forming mechanism, which comprises an inner revolving die, an outer revolving die, an injection member fixed on a chassis and a supporting sleeve ring arranged on the periphery of the outer revolving die. The utility model is characterized in that the injection member is provided with a row of needle valves which can block up a chain teeth mould cavity feed inlet of each loading zipper; a return spring is arranged between each needle valve and the injection mechanism. A follow-up rotating disc is fixedly connected with the edge side corresponding to the rotating shaft of the inner revolving die. A needle valve driving piece which is composed of a lower supporting body and an upper electric magnet body is buckled on the outer side edge of the follow-up rotating disc. When attracted, the upper electric magnet body can be contacted with the follow-up rotating disc. A pushing pressure spring is arranged between the upper electric magnet body and the lower supporting body. The side part of the upper electric magnet body is hinged with the outer side part of the lower supporting body. The inner side part is fixedly connected with a pushing block for pushing the needle valve while attracted. The needle valve driving piece is connected with the chassis by the return spring. The chassis is provided with a reset block which is positioned at the back side of the running direction of the needle valve driving piece and a travel switch which is arranged at the front side of the running direction and is used for disconnecting with the electric magnet.
Description
Affiliated technical field
The utility model relates to a kind of inch sign indicating number dress injection molding zipper shaping mechanism of deciding.
Background technology
The patent No. is the forming method that 01113581.6 patent of invention discloses a kind of injection molding zipper, its chain tooth was continuously when the weak point that this method exists was injection molding zipper, middle not interruption, thereby make when producing, manufacturer must destroy the tooth chain of injection formed the tooth chain that several teeth intercept Len req again and carry out processing, so not only increased operation, and waste material.
Summary of the invention
The purpose of this utility model is to provide a kind of inch sign indicating number dress injection molding zipper shaping mechanism of deciding, and it helps the user and injects a section at regular intervals decide inch sign indicating number dress slide fastener on continuous strap, thereby helps saving plastic raw materials and further production and processing.
The utility model is to constitute like this, it comprises interior revolving die, outer revolving die and is fixed in pouring member on the frame, and the supporting lasso of being located at outer revolving die periphery, it is characterized in that: (1) pouring member is provided with the row's needle-valve that can block each yard dress zipper sprocket die cavity charging aperture, is provided with back-moving spring between each needle-valve and the injection mechanism; (2) the described interior affixed servo-actuated rotating circular disk of the corresponding side of revolving die rotating shaft, buckle the needle-valve actuator that constitutes by lower support body and last electromagnet on the lateral border of servo-actuated rotating circular disk, can contact with the radially outer edge of servo-actuated rotating circular disk during the lower flange adhesive of last electromagnet, be provided with the pushing tow stage clip that they are separated between last electromagnet and the lower support body, the outside portion of the outside portion of last electromagnet and lower support body is hinged, and is used for the push block of pushing tow needle-valve when the inside portion is connected with adhesive; (3) described needle-valve actuator links through a return spring and frame, frame be provided with the reset baffle block that is positioned at needle-valve actuator direct of travel rear side and front side in order to disconnect the travel switch of electromagnet.
During work, strap (shown among Fig. 2 22) places interior revolving die upper surface and stretches into by interior revolving die and outer revolving die and fastens in the sprocket die cavity that forms, when revolving die rotates with interior revolving die outside strap reaches, the pouring member of plastic molten mass on being fixed in frame injects in the sprocket die cavity, forms sprocket continuously at the cloth belt surface.Form the sprocket of certain-length when the cloth belt surface after, electromagnet is connected and is made electromagnet and adhesive of servo-actuated rotating circular disk and rotation thereupon, the push block of its inside portion promotes the needle-valve reach, blocks the charging aperture of each yard dress zipper sprocket die cavity, and the tooth chain of cloth belt surface just forms vacancy.When the needle-valve actuator moves a period of time with the servo-actuated rotating circular disk after, touch the travel switch of being located at its direct of travel front side, electromagnet disconnects, last electromagnet unclamps the suction-combining force to the servo-actuated rotating circular disk, and move under the effect of its downside pushing tow stage clip and reset, and needle-valve also moves after under the action of reset spring between itself and the pouring member and resets, and this moment, sprocket die cavity charging aperture was connected, and injection mechanism continues toward cloth belt surface injection to form the plastic molten mass of sprocket.
Than existing injection moulding sign indicating number dress slide fastener shaping mechanism, the utility model can be made the needs of bar dress slide fastener length according to the user, zipper sprocket with the moulding on the cloth belt surface of certain hour interval interrupt, thereby produce a section and decide inch sign indicating number dress slide fastener, not only structure rationally, and helping reducing operation, economical with materials greatly facilitates user's use.
