Abstract
The utility model relates to an automatic thread demolding mold mechanism, which is composed of a pouring gate bush, a fixed mold plate, a movable mold plate, a thrust bearing, a deep groove bearing, a threaded core, a driven sprocket, a screw, a fixed mold seat plate, a movable mold seat plate, a guide sleeve, a guide post, a supporting block, a spring, a pouring gate push plate, a relay, a driving sprocket, a motor and the like. When the mold is opened to a certain distance, a molding equipment jacking rod enters the mold, so that a proximity switch is sensed and a signal is sent to start a motor, which drives the driving sprocket, a chain drives the driven sprocket to rotate, and thus a product is automatically moved out of the mold.
Description
Technical field
The present invention relates to die cast metal mould and plastic injection mould, is a kind of mold mechanism that takes off screw thread automatically.
Background technology
At present, have in the mechanism that die cast metal and plastic injection mould take off screw thread: (1) manually takes off screw thread; (2) there is motor drives to take off screw thread; (3) the moving screw thread that takes off of hydraulic pressure and zone of pressure is arranged.Though it is solid and reliable that above-mentioned these mechanism's mould emptiers move, pressure transmits, the product quality grace, and the manpower of dependence or mould opening force and machine driving are had plenty of by these mechanisms, its thread core or screw-type ring are rotated relatively carry out the demoulding.The artificial demoulding of the employing that these mould emptiers have causes labor strength big, and production efficiency is low, and workman's safety can not get ensureing.The employing motor, hydraulic pressure, the pneumatic demoulding that have, cause the mould structure complexity, more auxiliary component must be set simultaneously motor, hydraulic cylinder and pneumatic cylinder are installed, this brings to a line mould manufacturing inconvenience is installed, maintenance mould difficulty has improved die cost simultaneously.In order to overcome the defective of above-mentioned mold mechanism, I design and manufacturing experience in conjunction with mould for many years, and the spy provides following a kind of mold mechanism that automatically takes off screw thread, make the boundary for mould and use.
Summary of the invention
The present invention provides a kind of mold mechanism that takes off screw thread automatically, it is achieved in that as shown in the figure, after matched moulds, cast, pressurize, cooling procedure finish, mould is opened, dynamic model begins to move backward, cast gate push pedal (18) is coagulated material with sprue and goods are released from dynamic model under the effect of spring.Dynamic model, cover half die sinking are to certain distance, injector or die casting machine push rod enter mould by the hole that ejects of Bottom clamp plate, make near switch and responded to, subsequent signal is given auxiliary reclay, start drive sprocket, chain drives the driven sprocket rotation, and thread core rotates under the cooperation of thrust bearing and deep groove ball bearing.When the time relay then after outage, the mould drive sprocket stops action, core stops the rotation simultaneously, die sinking process of mould finishes, and finishes deviating from of goods.Automatically take off the mold mechanism of screw thread, it has solved, and employing hand ejection labor strength is big, and production efficiency is low, the problem that safety of workers can not get ensureing.When having solved employing motor, hydraulic cylinder, the pneumatic cylinder demoulding, the mould structure complexity must arrange more auxiliary component simultaneously motor, hydraulic cylinder, pneumatic cylinder are installed, and to the mould manufacturing inconvenience is installed, and maintenance difficult has improved the problem of die cost.Automatically take off the mold mechanism of screw thread, it is characterized in that: sprue bush (1) and top clamping plate (11), solid plate (2) matched in clearance, moving platen (3) is equipped with thrust bearing (5) and zanjon bearing (6), thread core (7) cooperates the back to use holding screw (9) lock then firmly at afterbody installation driven sprocket (8) with thrust bearing (5) and zanjon bearing (6) rotary gap, moving platen (3) is connected one with Bottom clamp plate (16) with screw with support plate (15), guide pillar (13) be installed in the moving platen (3) then be installed in solid plate (2) on guide pin bushing (12) glade plane space cooperate, spring (17) is installed in the hole of top clamping plate (11) and solid plate (2) uses screw (23) to be fastenedly connected then, cast gate push pedal (18) is installed in the solid plate (2) and is glade plane space and cooperates, auxiliary reclay (19), the time relay (20), electric capacity (21), be installed on the medial surface of support plate (15) near switch (22), drive sprocket (24) is installed on the rotating shaft of motor (26).
Description of drawings
Below in conjunction with accompanying drawing the utility model mold mechanism is further specified:
Sectional side elevation when Fig. 1 is the cast of mould matched moulds
Fig. 2 is mould matched moulds situation power drive mechanism sectional side elevation
Fig. 3 is mould sprocket wheel connection state figure
Numeral number is represented respectively among the figure:

25---fixed leg 26---motor
Concrete implementing measure:
It is the mold mechanism that takes off screw thread automatically shown in the figure, its mold work process is: after matched moulds, injection, pressurize, cooling procedure were finished, mould was opened, and dynamic model begins to move backward, cast gate push pedal (18) is coagulated material with sprue and goods are released from dynamic model under the effect of spring (17).Dynamic model, cover half die sinking are to certain distance, and injector or die casting machine push rod enter mould by the hole that ejects of Bottom clamp plate (16), make near switch (22) to be responded to, and subsequent signal is given auxiliary reclay (19), starter motor (25).Motor drives driven sprocket (8) rotation by drive sprocket (24), chain (14), and thread core (7) rotates under the cooperation of thrust bearing (5) and deep groove ball bearing (6).Goods and core are realized automatic demoulding under the effect of relative rotary motion.When time relay (20) automatic outage then, motor shuts down, and core stops the rotation simultaneously, finishes the moulding by casting of goods and deviating from of goods.
