Abstract
The utility model relates to a mold, in particular to a plastic-injection three-plate mold. The following technical scheme adopted by the utility model is that the plastic-injection three-plate mold is characterized in that an accommodating cavity is arranged on the side face of a panel, which is near one side of an upper mold plate; the accommodating cavity is located in an area formed by connecting lines of four pull rod guide pillars; a pull rod is arranged among the panel, a stripper plate and the upper mold plate; the length of the pull rod is greater than the thickness sum of the panel, the stripper plate and the upper mold plate; the lower end of the pull rod passes through the upper mold plate to extend into a lower mold plate; and the lower end part of the pull rod is provided with a boss for preventing the pull rod from being pulled out of the upper mold plate. Through adopting the technical scheme, the utility model provides the novel plastic-injection three-plate mold which can be widely used for the field of plastic-injection molding, is capable of greatly simplifying the use of the stripper plate in the three-plate mold and is simple in processing, low in material utilization amount, small in fitting part number and strong in generality.
Description
Technical field
The utility model relates to a kind of mould, refers to especially plastic injection mould.
Background technology
Existing injection molding can divide two template dies and three template dies from structure, also claims style big water gap and the thin mouth of a river, and three template dies can divide again common and two kinds of simplified styles.The existing three board mold stripper plates size the same with other template links to each other with guide pillar.Its materials'use is many, and processing capacity is large, also need be furnished with guide pin bushing, and material cost and processing cost are large.
Summary of the invention
The utility model has overcome the deficiency that prior art exists, and a kind of injection-moulding plastic field that is widely used in is provided, and has greatly simplified the use of stripper plate in three board molds, process easy, material usage is few, and accessory uses few, novel plastic injection three board molds of highly versatile.
Realize above-mentioned purpose, the utility model adopts following technical scheme: a kind of plastic injection three board molds, include panel, cope match-plate pattern, lower bolster, the mould pin, base plate and base, wherein between panel and the cope match-plate pattern and be positioned at four vertex angle parts and all placed the pull bar guide pillar, the length of pull bar guide pillar is greater than panel and cope match-plate pattern thickness sum, the two ends of pull bar guide pillar are provided with and prevent that panel and cope match-plate pattern break away from boss or the nut of pull bar guide pillar, it is characterized in that: described panel is provided with accommodating cavity near on the side of cope match-plate pattern one side, described accommodating cavity is between the zone that four pull bar guide pillar lines form, be provided with the suitable stripper plate of shape and size and accommodating cavity in this accommodating cavity, described panel, be provided with pull bar between stripper plate and the cope match-plate pattern, the length of pull bar is greater than panel, stripper plate and cope match-plate pattern three's thickness sum, described pull bar is fixedly connected with stripper plate, the pull bar upper end is flexibly connected with panel and the top is provided with the boss that prevents panel disengaging pull bar, described pull bar lower end is passed cope match-plate pattern and is stretched in the lower bolster, and end, pull bar lower end is provided with and prevents that pull bar from extracting the boss of cope match-plate pattern.
By adopting such scheme, in the situation that guarantees the injection molding channel layout, dwindle stripper plate, stripper plate is embedded in the accommodating cavity of panel, rely on around the stripper plate and the guiding of accommodating cavity wall (around the stripper plate be-0.05-0.10 with cover plate frame inwall fit clearance), replace original guide pillar guide pin bushing guiding, realize motion, reduced material cost and processing cost, shorten Production Time, reduce the mould volume.
Further setting of the present utility model is: described panel is rectangle near the accommodating cavity of the side of cope match-plate pattern one side, corresponding stripper plate also is rectangle, the thickness of stripper plate is suitable with the degree of depth of accommodating cavity, described base plate is arranged between lower bolster and the base, be fixedly installed push rod on the base plate, the push rod end is passed on the die cavity that lower bolster places upper and lower template.
Adopt the purpose of such scheme to be, make product structure more reasonable, use convenient.
Below in conjunction with accompanying drawing the utility model is further described:
