Abstract
The utility model relates to a kind of mold ejection mechanism that prevents deformation of products, comprise cover half, dynamic model and push rod, described fixed half and moving half is up and down to be arranged, the middle inside of between is furnished with respectively cover half core rod and dynamic model core rod, between described cover half core rod and dynamic model core rod, be in contact with one another and form die cavity, described push rod is vertically arranged in cover half and one end is connected with die cavity, the other end is through being positioned at the push rod fixed head of cover half and being connected with the push rod pressing plate that presses push rod fixed head top, described push rod pressing plate top contacts with the piston rod that is arranged in the unidirectional ejection cylinder front end on cover half top.The utility model is simple in structure, by unidirectional ejection cylinder and push rod fixed head, replaces traditional spring, makes ejecting mechanism energy balance ejecting product, has reduced the deflection of product.
Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of mold ejection mechanism that prevents deformation of products.
Background technology
Mould, after die sinking, need to eject the foundry goods in die cavity, and general ejecting mechanism is by the tail end mounting spring of push rod, by the elastic force of spring, carrys out ejecting product.But spring has been used of a specified duration and will have been made spring toughness reduce gradually, while making ejecting product, can cause the deflection of product to strengthen because ejecting imbalance, and this has increased the workload of subsequent operation shaping undoubtedly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mold ejection mechanism that prevents deformation of products, simple in structure, by unidirectional ejection cylinder and push rod fixed head, replace traditional spring, make ejecting mechanism energy balance ejecting product, reduced the deflection of product.
The utility model solves the technical scheme that its technical problem adopts: a kind of mold ejection mechanism that prevents deformation of products is provided, comprise cover half, dynamic model and push rod, described fixed half and moving half is up and down to be arranged, the middle inside of between is furnished with respectively cover half core rod and dynamic model core rod, between described cover half core rod and dynamic model core rod, be in contact with one another and form die cavity, described push rod is vertically arranged in cover half and one end is connected with die cavity, the other end is through being positioned at the push rod fixed head of cover half and being connected with the push rod pressing plate that presses push rod fixed head top, described push rod pressing plate top contacts with the piston rod that is arranged in the unidirectional ejection cylinder front end on cover half top.
As a kind of optimal way of mold ejection mechanism described in the utility model, described push rod has several, and is arranged in around unidirectional ejection cylinder, by these push rod actings in conjunction, and by the power of unidirectional ejection cylinder, final ejecting product.
As a kind of of mold ejection mechanism described in the utility model, supplement, the piston rod center superposition that ejects make a concerted effort equalization point and unidirectional ejection cylinder of several push rods, can be the power optimization ejecting, more rapidly and accurately ejecting product.
As the another kind of optimal way of mold ejection mechanism described in the utility model, described push rod fixed head downside, push rod one side are furnished with and eject front limit piece, have guaranteed that push rod can eject work smoothly, increases work efficiency.
Another kind as mold ejection mechanism described in the utility model supplements, and described unidirectional ejection cylinder is connected with the one end that is the horizontally disposed oil inlet pipe on cover half top, and the other end of described oil inlet pipe is connected with oil pump.
beneficial effect
The utility model relates to a kind of mold ejection mechanism that prevents deformation of products, simple in structure, by unidirectional ejection cylinder and push rod fixed head, replaces traditional spring, makes ejecting mechanism energy balance ejecting product, has reduced the deflection of product.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks sectional structure chart;
Fig. 2 is plan structure figure of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, embodiment of the present utility model relates to a kind of mold ejection mechanism that prevents deformation of products, comprise cover half 1, dynamic model 2 and push rod 6, described cover half 1 and dynamic model 2 are up and down to be arranged, the middle inside of between is furnished with respectively cover half core rod 3 and dynamic model core rod 4, between described cover half core rod 3 and dynamic model core rod 4, be in contact with one another and form die cavity 5, described push rod 6 is vertically arranged in cover half 1 and one end is connected with die cavity 5, the other end is through being positioned at the push rod fixed head 7 of cover half 1 and being connected with the push rod pressing plate 8 that presses push rod fixed head 7 tops, described push rod pressing plate 8 tops contact with the piston rod that is arranged in unidirectional ejection cylinder 9 front ends on cover half 1 top.
Described push rod 6 has several, and is arranged in around unidirectional ejection cylinder 9.
The piston rod center superposition that ejects make a concerted effort equalization point and unidirectional ejection cylinder 9 of several push rods 6.
Described push rod fixed head 7 downsides, push rod 6 one sides are furnished with and eject front limit piece 11.
Described unidirectional ejection cylinder 9 is connected with the one end that is the horizontally disposed oil inlet pipe 10 on cover half 1 top, and the other end of described oil inlet pipe 10 is connected with oil pump.
Embodiment
Oil pump is given unidirectional ejection cylinder 9 fuel feeding by oil inlet pipe 10, and unidirectional ejection cylinder 9 provides power, these push rod 6 actings in conjunction straight down ejecting product to being arranged in its push rod 6 around.Described push rod 6 other ends are connected with push rod fixed head 7, and the connection of this rigidity makes the product that ejects more even.By this series of layout, replaced the spring of original use, make to eject unbalanced phenomenon and substantially can eliminate, the deflection of product is less.
