Description
Technical field
The utility model relates to mold ejection mechanism.
Background technology
Existing mold ejecting mechanism, general employing be combinationally using of push rod and back-moving spring, push rod ejects this action of workpiece and produces through spring deformation, due to spring deformation the power produced for ejecting workpiece be limited, and this power is also moment, cause the effect of ejection workpiece unsatisfactory, the situation that workpiece can not eject by easy appearance, for can not by the situation of workpiece from mold ejection, also need staff to apply extra power workpiece to be taken out from mould, cause production efficiency low, particularly after such ejecting mechanism is when using longer, the spring life of the reset response played declines, namely occur that the elastic force of spring is not enough, cause occurring that the above-mentioned situation that workpiece can not be ejected can be more frequent, have impact on production efficiency, it should be appreciated that more in addition, time such ejecting mechanism is for thin plastic product (workpiece), push rod ejects this action of workpiece and produces through spring deformation, this action is had an effect instantaneously, the distortion of the workpiece of thin plastic may be caused, easy generation produces waste product.
Utility model content
The technical problems to be solved in the utility model is, provides one to facilitate workman to take out workpiece from mould, with this rate of reducing the number of rejects and seconds, improves the mold ejection mechanism of the production efficiency of workpiece.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of mold ejection mechanism, it comprise offer cavity supporting seat, push part and power transmission shaft in axial sliding; The described part that pushes comprises the first push rod and the second push rod; The first gear bar is vertically provided with in described cavity; A brace table is also provided with in described cavity; One end of described power transmission shaft is connected with the bottom of brace table, and the free end shaft of power transmission shaft is to outside the bottom of extending supporting seat; Described a kind of mold ejection mechanism also comprises gear; Described gear is rotatably connected in brace table by axle or pin; The first described gear bar pass vertically through brace table and and gears meshing, one end of the first gear bar is fixedly connected with the upper surface of cavity, and the other end of the first gear bar is fixedly connected with the lower surface of cavity; One end of the first described push rod is connected with the second gear bar; The second described gear bar to be vertically located in brace table and and gears meshing; The first chute that cooperation second gear bar slides is provided with in described brace table; The second described push rod is positioned at the opposite side of the first gear bar; Described one end of the second push rod is connected with the upper end of brace table; The through hole that the first described push rod and the free end of the second push rod are provided with supporting seat top is respectively slidably matched; The upper surface of described cavity is provided with the 3rd push rod for withstanding brace table.
Compared with prior art, the utility model has the advantages that: after work pieces process completes, equipment can apply the power of an axis to power transmission shaft, power transmission shaft up moves, promote brace table to move upward along the first gear bar, first push rod and the second push rod move upward along with brace table, the tooth of gear and engaging of the first gear bar, when brace table move upward backgear occur rotate, pinion rotation drives the second gear bar to move up, also the first push rod can be made to move up, the length that finally the first push rod can be made to extend the end face of the upper end of supporting seat is greater than the length that the second push rod extends the end face of the upper end of supporting seat, workpiece is finally occurred to eject obliquely, the process of pinion rotation is slowly individual, progressive process, damage can not be caused to the workpiece of thin plastic, reduce percent defective, the length that first push rod extends the end face of the upper end of supporting seat is greater than the length that the second push rod extends the end face of the upper end of supporting seat, serve and facilitate workman to be taken out from supporting seat by workpiece, easily there is tired phenomenon in the process customer service of gear driven spring, improve production efficiency.
As preferably, described gear engages with the tooth above the second gear bar.The object adopting design is like this to make the first push rod be connected with the second gear bar have enough strokes, ensure that the length that the first push rod extends the end face of the upper end of supporting seat is greater than the length that the second push rod extends the end face of the upper end of supporting seat, eject workpiece to realize inclination.
As preferably, the 3rd described push rod adjustable length.What adopt design like this is the vary in length of extending the end face of the upper end of supporting seat in order to realize the first push rod, and the second push rod extends the vary in length of the end face of the upper end of supporting seat.Namely the 3rd push rod shortens after regulating, meaning brace table can move up larger distance, illustrate that the first push rod extends the length change of the end face of the upper end of supporting seat greatly, the length that the second push rod extends the end face of the upper end of supporting seat becomes large, can take out workpiece more easily.
As preferably, in described brace table, be provided with the second chute coordinating and realize brace table and can slide along the first gear bar.Adopt the object of like this design to be the second chute to be to better realize being slidably matched of uni-drive gear box and the first gear bar.
