Abstract
The invention discloses a plastic mold for the molding of front covers of round bases of knob switches. For the plastic mold, a moving die and a fixed die are correspondingly occluded so as to form a molding form cavity, the molding form cavity is provided with an elliptical ring cavity, vertical-sided cavities extend downwards from the outer edge of the elliptical ring cavity, the vertical-sided cavities at the front and rear ends of the elliptical ring cavity are respectively provided with a semi-circular wire passing groove, the posterior end of the upper wall surface of the elliptical ring cavity is provided with a small round hole cavity, the edge of the small round hole cavity is provided with a raised annular step cavity, the left and right sides of the raised annular step cavity are respectively provided with a circular arc boss cavity, the outer side of each circular arc boss cavity is provided with a threaded hole cavity, the inner circular arc wall of the elliptical ring cavity is provided with an annular groove, the upper edge of the annular groove is provided with four rectangular open clamp slots, and the four rectangular open clamp slots are distributed in a quartering mode. Through the way, front covers of round bases of knob switches can be rapidly molded, thereby improving the production efficiency of the mold; and the rate of finished products is increased, and the waste of resources is avoided.
Description
Technical field
The present invention relates to plastic rubber shaping mould, particularly relate to a kind of rotary switch circular seat protecgulum plastic rubber mold.
Background technology
In recent years, along with the develop rapidly of plastics industry and general, engineering plastics improving constantly in intensity and precision etc., make the range of application of plastic products also in continuous expansion, as various fields such as household electrical appliance, instrument and meter, construction equipment, auto industry, haberdashery and hardware, the ratio shared by plastic products just rapidly increases.Along with growing to plastic cement products demand of people, the output of mold is had higher requirement.But with existing Tool and Die Technology, increase injection machine and die apparatus only can be relied on to realize for enhancing productivity, but this not only can increase hardware cost, and the operating cost such as electric energy, water energy of corresponding plant maintenance expense and consumption and labour cost are also no small expenses, therefore, the huge growth of production cost seriously limits the development of plastic cement industry.This plastic parts of product requirement on existing market has higher dimensional accuracy and shaped interface, and existing plastic mould shaping efficiency is low, and yield rate is low, causes substantially increasing production cost, waste resource.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rotary switch circular seat protecgulum plastic rubber mold, rotary switch circular seat protecgulum can be made shaping rapidly, improve the production efficiency of plastic mould, improve yield rate simultaneously, reduce production cost, avoid the wasting of resources.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of rotary switch circular seat protecgulum plastic rubber mold, this rotary switch circular seat protecgulum plastic rubber mold comprises fixed half and moving half, the solid plate of described cover half is provided with guide pin bushing, mobilizable guide pillar is inserted with in guide pin bushing, guide pillar is fixed on the moving platen of dynamic model, and dynamic model carries out open and close movement by guide pillar, be engaged corresponding with cover half of described dynamic model forms a shaping shape chamber afterwards, shaping shape chamber is provided with an oval ring cavity, the outer edge of oval ring cavity extends stile chamber downwards, the stile chamber of oval ring cavity rear and front end has semi arch and leads to wire casing, the upper wall surface of oval ring cavity is held rearward and is provided with a roundlet vestibule, the edge of roundlet vestibule is provided with protruding circular step chamber, the left and right sides, circular step chamber is provided with circular arc boss chamber, the outside in circular arc boss chamber is equipped with a screw vestibule, the Inner arc wall of oval ring cavity has annular groove, the upper edge of annular groove is provided with four rectangular aperture draw-in grooves, four rectangular aperture draw-in grooves become the quartering to arrange.
The invention has the beneficial effects as follows: a kind of rotary switch circular seat of the present invention protecgulum plastic rubber mold, rotary switch circular seat protecgulum can be made shaping rapidly, improve the production efficiency of plastic mould, improve yield rate simultaneously, reduce production cost, avoid the wasting of resources.
