Abstract

The invention discloses a plastic mold for driving sliding blocks by a fixed mold push plate and a mold release method using the same. The mold comprises the fixed mold push plate and a movable mold push plate at the same time, and four sides of the mold are designed with a structure that four sliding blocks can be opened on four sides. After injection molding and cooling are finished, the fixed mold push plate drives the four sliding blocks to slide and open so as to finish side core pulling. The plastic mold can be used for manufacturing large plastic products with many interweaving positions, has good use effect, is convenient for mold release of the products, has no defects of straining and damaging the products and the like, and has high yield; the mold has a stable structure and high production efficiency; and the integral appearance of the mold is reduced, the cost of the mold is lowered, the tonnage of an injection molding machine is reduced, and the injection molding cost is lowered.

Description

A kind of cover half push pedal drives plastic mould and the release method of slide block
Technical field
The present invention relates to a kind of injection mold, particularly a kind ofly contain cover half push pedal and dynamic model push pedal simultaneously, and drive the plastic mould that slide block is finished side core-pulling by the cover half push pedal.The invention still further relates to the method with this mold releasability.
Background technology
Plastic box is a kind of widely used plastic products, because the reason of plastics rigidity deficiency, one has all designed reinforcement plastic box, so the Turnover Box mould will be designed to the structure that 4 slide blocks are opened on four sides, in order to can take out product.Traditional Turnover Box mould substantially all adopts the structure that 4 slide blocks is located at dynamic model.Do not have push pedal but the shortcoming of this class formation is dynamic model, adopt conventional thimble to eject because it is little to eject area, when article construction complexity or reinforcement more for a long time, tend to take place product and can not push up or push up white phenomenon.The patent 200520090706.8 that is disclosed " a kind of pintongs side core-pulling plastic injection mould " has been done effective improvement to this, and four slide blocks are located in the dynamic model push pedal, and after slide block sliped off, the dynamic model push pedal drove slide block and moves together, and plastic is ejected.But this kind structure is because slide block is located in the dynamic model push pedal, and after slide block sliped off, its stability was good inadequately, and the dynamic model push pedal drive to need slide block to move together, and the dynamic model push pedal needs enough abundant, so can't be used for the mould of large-sized plastic rubber goods.
As mould slide block is located at cover half, the dynamic model push pedal has not just been influenced by slide block, adopt the technology of mentioning in the disclosed patent 200910164709.4 " the oblique core-pulling device of injection mold cover half " this type of mould can be designed to the structure shown in the figure four, slide block is located at cover half.But when product is to intert the more large-sized plastic rubber goods in position, when dynamic model, cover half product Bao Li were big, dynamic model, cover half needed to adopt push pedal simultaneously, and two kinds of above-mentioned prior art schemes just can't realize, so need be improved.
Summary of the invention
In order to solve the problems of the technologies described above, it is succinct to the invention provides a kind of processing technology, contains cover half push pedal and dynamic model push pedal simultaneously, and drives the injection mold that Four-slider is finished side core-pulling by the cover half push pedal.In addition, the present invention also will provide the method for this mold releasability of a kind of usefulness.
The present invention is achieved by the following technical solutions: the present invention is a kind of contain simultaneously cover half push pedal and dynamic model push pedal, and drive the injection mold that Four-slider is finished side core-pulling by the cover half push pedal, comprise top clamping plate, hot flow path, cover half, slide block pilot pin, slide block, T shape guide plate, dynamic model push pedal, push pedal dagger, push rod, face needle plate, end needle plate, dynamic model seat, dynamic model, moving-mould-core, cover half push pedal, cover half core, cylindricality oil cylinder.A kind of cover half push pedal drives the plastic mould of slide block, comprise top clamping plate, hot flow path, cover half, slide block pilot pin, slide block, T shape guide plate, dynamic model push pedal, push pedal dagger, push rod, face needle plate, end needle plate, dynamic model seat, dynamic model, moving-mould-core, cover half push pedal, cover half core, cylindricality oil cylinder, it is characterized in that: described hot flow path is fixed on top clamping plate topmost and is close to center position between the cover half under it; Described cover half core is fixed on the cover half, and below hot flow path and run through the cover half push pedal downwards, be deep in the moving-mould-core; Described cylindricality oil cylinder in the cover half push pedal, hot flow path one side, be connected with the cover half push pedal; Described slide block pilot pin is fixed on the cover half push pedal left and right sides, and contacts with slide block and can horizontally slip along the axis direction of slide block pilot pin; Described T shape guide plate be fixed on the cover half and the cover half push pedal tiltedly below; Four sides of described slide block in cover half have and the corresponding T type of T shape guide plate groove above; Described moving-mould-core is fixed on the center position on the dynamic model; Be face needle plate and the end needle plate that is fixed together below moving-mould-core, the face needle plate is above end needle plate; Described push pedal dagger is in a side of face needle plate, and its lower end is fixed on the end needle plate, and its first half is passed dynamic model, fixedlys connected with the dynamic model push pedal on dynamic model; Described push rod is fixed on the end needle plate, and an end passes dynamic model and links to each other with the cover half core; Needle plate is above the dynamic model seat at the described end; The described dynamic model push pedal that is fixed together, push pedal dagger, push rod, face needle plate, end needle plate can slide in described dynamic model together; Described cover half is fixed together with the dynamic model seat of below.
Described cylindricality oil cylinder is fixed between top clamping plate and the cover half, in a side of hot flow path, and is connected with described cover half push pedal, can promote the cover half push pedal to lower slider.
Method with the demoulding of the present invention comprises following several steps:
Earlier the cylindricality oil cylinder is connected with injection machine, and sets it and the injection moulding machine mould open oil cylinder is synchronous; After injection moulding was finished, and cooling finishes, injection machine was given cylindricality oil cylinder fuel feeding, and the cylindricality oil cylinder promotes the cover half push pedal and moves downward, and cover half push pedal simultaneously and slide block pilot pin promote slide block together and slide along T type groove direction; Meanwhile, injection moulding machine mould open, dynamic model move backward and separate with cover half; The cover half push pedal under the effect of cylindricality oil cylinder, promote certain stroke after, slide block separates fully with goods, cover half push pedal and slide block stop motion, dynamic model continues motion backward, after the shape journey of setting, the dynamic model stop motion, the die sinking action is finished; Enter next and eject action, under the effect of injection machine push rod, the injection machine push rod promotes end needle plate, and drives dynamic model push pedal, push pedal dagger, push rod, face needle plate together forward, and the dynamic model push pedal is held the goods outer goods are ejected, and finishes goods demoulding action.
