Abstract
The utility model discloses a mold for a product of a cylinder with a deep cavity and a groove in the wall. Springs are arranged in holes of a push plate and a push rod fixing plate and then are supported by a guide column which is arranged on a moving die seat plate; a guide sleeve is fastened in a two-step hole of a supporting plate; a push rod is arranged in a step hole of the push rod fixing plate and then is in clearance fit with a resetting rod fixing plate, the supporting plate and a core; a wedging rod is in the clearance fit with an inclined plane of the core; a slide block is arranged in a sliding guide groove of the supporting plate and is in sliding fit with the sliding guide groove; a conical surface positioning pin is fastened in a cavity plate and then is in conical surface sliding fit with a conical hole in the slide block; an inclined guide column is arranged in an inclined hole of the cavity plate and then is in the clearance fit with an inclined hole in the slide block; a sprue bush is in sliding clearance fit with the cavity plate; the core is in the clearance fit with a water distribution plate of a cooling water passage; the supporting plate, a die foot and the moving die seat plate are firmly connected by using inner hexagon screws; the positioning plate is concavely and convexly matched with the moving die seat plate and then is fastened by using connecting screws. The mold has the advantages of simple structure, good pressure transmission and firm and reliable action, and is suitable for forming a metal die casting simultaneously.
Description
Technical field
The present invention relates to plastic shaping and mould, is that a kind of goods are with the mould of groove on the dark chamber of cylinder, wall.
Background technology
At present, mould circle on the dark chamber of cylinder and wall with the Design of Dies of snap fit and groove, be all to adopt hydraulic cylinder, pneumatic cylinder and rack-and-pinion to complete loosing core of snap fit on wall and groove, then adopt compressed air to eject goods.Although above-mentioned mold mechanism mold actions is good, goods are of fine quality, but because hydraulic cylinder, pneumatic cylinder and rack-and-pinion will be arranged on the mould lateral surface, then connect the mold part of loosing core, its process is very complicated, must manufacture the auxiliary component of a lot of installation hydraulic cylinders, pneumatic cylinder and gear, tooth bar simultaneously, this brings very big inconvenience to mould manufacture, installation, debugging and maintenance, die cost increases substantially simultaneously, and die manufacturing cycle is very long, affects new product release.The mould volume increases on the other hand, very difficult in the selection of injector, must select with the large-scale injector of special use that drives hydraulic cylinder, pneumatic cylinder and just can be produced.In order to overcome the problems referred to above, the spy provides following a kind of mould to solve the problems referred to above.
Summary of the invention
It is with the mould of groove on the dark chamber of cylinder, wall that the present invention is to provide a kind of goods.The characteristics of this mould: the goods diameter is 200mm, is highly the dark chamber of cylinder of 180mm, and is used for hooking external equipment buckle and snap fit with 6 grooves on the goods wall.Because product material is that hard plastic is not suitable for forcing the demoulding of release mode, therefore this mould adopts the interior side core-pulling mechanism of 6 slide blocks to realize the demoulding of goods.During die sinking, goods stay in dynamic model, and compressed spring upwards promotes the release link fixed head, make the relative slide block movement of wedging bar, and slide block just can be made radial action like this.Leave gap between slide block and Angle Pin, so the action of loosing core of slide block slightly has hysteresis simultaneously.The release link fixed head is encountered stop motion after support plate.Finally by the machine tool hydraulic liftout attachment, promote push pedal, ejector pin retaining plate and push rod reset.A kind of goods are the dark chambeies of cylinder, on wall with the mould of groove, it is characterized in that: spring (1) is arranged in the hole of push pedal (17) and ejector pin retaining plate (16), then by being arranged on Bottom clamp plate (18) upper guide post (23) supporting, guide pin bushing (2) is fastened in the two stage steps hole of support plate (13), push rod (3) is arranged in the stepped hole of ejector pin retaining plate (16), then with release link fixed head (14), support plate (13), core (11) matched in clearance, wedging bar (14) and core (11) inclined-plane matched in clearance, slide block (5) is arranged in the guide runner of support plate (13) and becomes to be slidably matched, conical-surface positioning pin (6) becomes the conical surface to be slidably matched with the taper hole on slide block (5) after being fastened in cavity plate (9) again, Angle Pin (7) is arranged in the inclined hole of cavity plate (9) and then with the inclined hole on slide block (5), becomes matched in clearance, sprue bush (8) coordinates with cavity plate (9) glade plane space, core (11) becomes matched in clearance with cooling water channel distributive pipe (10), support plate (13), mould pin (15) and Bottom clamp plate are fastenedly connected with soket head cap screw, location-plate (19) with after concavo-convex cooperation of Bottom clamp plate (18), then use attachment screw (20) fastening.A kind of goods be on the dark chamber of cylinder, wall with the mould of groove, solved when hydraulic cylinder, pneumatic cylinder, rack-and-pinion are loosed core mould structure complicated and manufacture hydraulic cylinder, pneumatic cylinder, the required more problem of auxiliary component of rack-and-pinion of installing.Solved the problem that die cost increase, die manufacturing cycle are long, affect launch simultaneously, also solved that the mould volume is large, the very difficult problem of selection injector.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described

The specific embodiment:
That a kind of goods are with the mould of groove on the dark chamber of cylinder, wall as shown in the figure, when clamping mould to after on injector, through injection, pressurize, cooling after, mould is opened under the power of injector, now goods are pulled to dynamic model one side, at this moment compressed spring (1) upwards promotes release link fixed head (14), makes wedging bar (4) slide block (5) motion relatively, and slide block just can be done movement radially like this.Because having reserved the gap of 5-6mm between slide block (5) and Angle Pin (7), so the action of loosing core of slide block (5) is delayed.Release link fixed head (14) is encountered the rear stop motion of support plate (13).Finally by the machine tool hydraulic liftout attachment, promote push pedal (17), drive and be arranged on push rod (3) pushing out product on ejector pin retaining plate (16).During matched moulds, slide block (5) under Angle Pin (7) drives to mould outside side shifting, by wedging bar (4) and conical-surface positioning pin (6) assurance, resetted.At this moment, after release link (12) resets release link fixed head (14) and wedging bar (4), spring (1) is compressed power again.
