Description
Technical field
The present invention relates to a kind of injection mold, particularly a kind of injection mold of three punishment moulding surface structure.
Background technology
Injection-moulding plastic is a kind of important side of one of efficient production method of plastic products and plastic shaping
Method.It is primarily adapted for use in the molding of thermoplastic.Die joint be on mold for take out plastic or
The separable contact surface of gating system of material.The design of injection mould die joint directly affects plastic article matter
Amount, mould structure and the complexity of operation are the key that one of injection molding design success or failure.According to the quantity of die joint, can be divided into
Single die joint injection mold and multiple parting lines injection mold.
Ordinary circumstance multiple parting lines injection mold is more complicated than single die joint injection mold structure, manufacture requirement
It is high, of high cost, but production efficiency is high.Have by the position point of die joint perpendicular to die sinking direction, be parallel to die sinking side
To and favour die sinking several die joints in direction.There is plane die joint by the shape point of die joint
, curved surface die joint and stairstepping parting.When designing plastic mould, the selection of die joint is in an important design
Hold.Die joint selection reasonable mould is simple, and plastic is easily molded, and plastic part quality is high.The mould if die joint selection is unreasonable
Lamps structure becomes complicated, and plastic parts moulding is difficult, and plastic part quality is poor.
Rotary switch cover it is especially common on household appliances, for example, a kind of rotary switch lid stated in Fig. 1.It is above-mentioned
Rotary switch, which covers, is formed with through-hole, and male and fomale(M＆F) is formed on its inner wall, therefore the rotary switch of above structure is covered and noted
Modeling processing is needed using multiple parting lines injection mold, and needs to combine upper core-pulling mechanism in specific mould structure.It is existing, above-mentioned rotation
Turning the multiple parting lines injection mold of switch cover, there are complicated, the cumbersome technological deficiencies of knockout course.
Invention content
It is provided at a kind of structure relatively simple three the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art
The injection mold of parting surface structure.
To achieve these goals, the injection mold of a kind of three punishment moulding surface structure designed by the present invention, including cover half
Partly, dynamic model part and ejector pin mechanism, when the cover half part is in molding state with dynamic model part, cover half part is determined
Both mold core and the moving-mould-core of dynamic model part are collectively formed for a kind of band through-hole of injection molding, and male and fomale(M＆F) is formed on inner wall
The product cavity of rotary switch lid；
The cover half fixed plate of the cover half part is equipped with one slanted angle of die sinking direction formation relative to mold
Oblique shifting block, the oblique shifting block sequentially pass through model frame and the sliding block being articulated in model frame, and the sliding block, which is equipped with, to be taken out
Core, the core pulling run through cover half core, and extend into above-mentioned product type chamber, for be molded above-mentioned rotary switch cover it is logical
Hole；
The side of the lower liftout plate of the ejector pin mechanism is equipped with oblique pin base fixed plate, in the side of the oblique pin base fixed plate
Equipped with extending the oblique pin base fixed plate, but the telescopic block in oblique pin base fixed plate can be pressed into again under external force,
The guide holder that straight slot is formed on the stripping direction of mold, the guide holder are installed on the dynamic model installing plate of the dynamic model part
Straight slot groove face be equipped with the first recess, above-mentioned telescopic block is located in first recess, on above-mentioned first recess with ejector pin mechanism
The unilateral side that the ejection direction of middle thimble is consistent forms the scarf that telescopic block can be pressed into oblique pin base fixed plate, above-mentioned logical
It is movably equipped in slot and carries block, the upper ejector plate for carrying block and ejecting mechanism and/or lower liftout plate are mutually fixed, and described are carried on block
Equipped with the second recess that can catch on above-mentioned telescopic block；Oblique pin base is equipped in the oblique pin base fixed plate, the oblique pin base exists
The lower liftout plate and upper ejector plate of above-mentioned ejecting mechanism are sequentially passed through on the stripping direction of mold, and is extended into above-mentioned dynamic model
In default through-hole on partial dynamic model frame, and T-shaped sliding slot is formed in its end, phase is slidably connected on the T-shaped sliding slot
The taper pin of one slanted angle is formed for the die sinking direction of mold, the taper pin runs through the moving-mould-core of above-mentioned dynamic model part, uses
In the male and fomale(M＆F) being molded on the inner wall of above-mentioned rotary switch lid.
Above-mentioned provided a kind of three punish the injection mold of moulding surface structure, are included in the entire knockout course of injecting products
Die joint separation three times.It is exactly specifically：First, the cover half part of above-mentioned injection mold carries out die sinking behaviour with dynamic model part
Before work, the cover half fixed plate of above-mentioned cover half part is detached with model frame on the stripping direction of mold, at this time due to cover half
Be fixed with oblique shifting block in fixed plate, linear motion of the oblique shifting block on stripping direction can drive sliding block on cover half block perpendicular to
It is subjected to displacement on the stripping direction of mold, so as to which core pulling be driven to be detached from the completion of product type intracavitary, so far, above-mentioned injection mould
First die joint of tool completes separation；Then, die sinking action is completed in above-mentioned cover half part with dynamic model part, so far above-mentioned note
Second die joint of mould completes separation；Finally, the ejector pin mechanism of above-mentioned injection mold starts to act, and upper ejector plate is under
Liftout plate when injecting products are ejected from moving-mould-core by thimble, it is synchronous by carry block drive oblique pin base fixed plate along
The ejection direction of thimble is moved, until the telescopic block for extending oblique pin base fixed plate side originally is directed to the beveling on seat
Face is pressed into oblique pin base fixed plate, and carrying block at this time can not drive oblique pin base fixed plate to continue and upper ejection by catching on telescopic block again
Plate and lower liftout plate continue to move on thimble ejection direction, and oblique pin base fixed plate drives oblique pin base toward thimble ejection direction
Counter motion, the taper pin being slidably connected in the T-shaped sliding slot of oblique pin base are subjected to displacement on the stripping direction perpendicular to mold, until
Until this, the third die joint of above-mentioned injection mold completes separation.
The present invention obtain it is a kind of three punishment moulding surface structure injection mold, injection mold three at die joint three times
Separation process is simple, during the rotary switch lid that male and fomale(M＆F) is formed in a kind of band through-hole of injection molding, and on inner wall, life
It is low to produce failure rate, production efficiency is high.
