Abstract
The utility model discloses an ejector structure used for forming a product provided with a circular-arc-shaped inner top face and equipped with an inverted buckle on the inner side. The ejector structure comprises a straight top, an inclined top and a core insert, wherein the straight top comprises a straight mandrel and a first forming part used for forming the circular-arc-shaped inner top face of the product, and the straight mandrel and the first forming part are mutually combined and fixed; the inclined top is arranged on one side of the straight top, the inclined top is provided with an inclined mandrel and a second forming part extending out of one side of the inclined mandrel, and the second forming part is used for forming the inverted buckle of the product; the core insert is used for forming the inner surface of the product in cooperating with the first forming part and the second forming part. When a mold is opened, the straight top ejects the product along the mold opening direction, meanwhile, the inclined top obliquely retreats in a manner of forming an inclination angle with the mold opening direction, and after the second forming part completely retreats from the inverted buckle, the product can be taken out. Therefore, the ejector structure has a simple structure and can achieve the forming and retreating of the product provided with the circular-arc-shaped inner top face and equipped with the inverted buckle on the inner side.
Description
[technical field]
The utility model relates to a kind of ejecting structure, particularly relates to the ejecting structure that a kind of straight top adds oblique top.
[background technology]
On many plastic cement products, all can there is back-off, when using mould to carry out moulding, just need to design corresponding structure it is exited.
Refer to Fig. 1, Fig. 1 illustrates the structural representation into a kind of product.As shown in the figure, the end face of described product 10 is circular-arc, and described product 10 has back-off 11 near the inner side of bottom.Moulding to this series products 10, exiting of back-off 11 becomes problem demanding prompt solution.
Refer to Fig. 2, Fig. 2 illustrates a kind of ramp-roof structure schematic diagram into prior art.Adopt product 10 described in these oblique top 12 moulding, when exiting, because the inner top surface of described product 10 is circular-arc, oblique top 12 can shovel glue, so the method is inadvisable.And if the structure that adopts oblique top 12 side direction to exit, space is not enough again.
Refer to Fig. 3, Fig. 3 illustrates a kind of inner slide block structure schematic diagram into prior art.Adopt this inner slide 22 can moulding inner side there is the product 20 of back-off 21.Yet as shown in the figure, described inner slide 22 structures are too complicated.
In view of this, be necessary to develop a kind of ejecting structure in fact, to address the above problem.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of ejecting structure, solves moulding and has the product that circular-arc inner top surface and inner side have back-off, the problem of exit structure complexity.
In order to achieve the above object, the ejecting structure that the utility model provides, moulding has the product that circular-arc inner top surface and inner side have back-off, and this ejecting structure comprises:
Straight top, it comprises the first forming part of straight push rod and the circular-arc inner top surface of shaped article, described straight push rod and described the first forming part mutually combine fixing;
Oblique top, it is located at described straight top one side, and described oblique top has angle ejector rod and extended the second forming part of described angle ejector rod one side, the described back-off of product described in described the second forming part moulding;
Male die core, coordinate moulding with described the first forming part, the second forming part described in the inner surface of product.
Optionally, described straight push rod is combined fixing between described the first forming part by screw.
Optionally, described straight push rod is two.
Compared to prior art; utilize ejecting structure of the present utility model; during die sinking; described straight top ejects product along die sinking direction; simultaneously described oblique top is along having oblique the exiting of angle at certain inclination angle with die sinking direction; when described the second forming part exits after back-off (in order to ensure safety, conventionally also will exit a safe distance) completely again, can take out described product.Visible, said structure is simple and can solve and have circular-arc inner top surface and inner side has the moulding of torque product and exits.

[specific embodiment]
Please jointly consult Fig. 4, Fig. 5, perspective view, Fig. 5 that Fig. 4 illustrates as ejecting structure one preferred embodiment of the present utility model illustrate the decomposition texture schematic diagram into ejecting structure one preferred embodiment of the present utility model.
In order to achieve the above object, the ejecting structure that the utility model provides, moulding has product 10(that circular-arc inner top surface and inner side have back-off 11 please again in conjunction with consulting Fig. 1), this ejecting structure comprises:
Straight top, it comprises the first forming part 101 of the circular-arc inner top surface of straight push rod 100 and shaped article 10, described straight push rod 100 mutually combines fixing with described the first forming part 101.
Oblique top, it is located at described straight top one side, and described oblique top has angle ejector rod 102 and extended the second forming part 103 of described angle ejector rod 102 1 sides, the described back-off 11 of product 10 described in described the second forming part 103 moulding;
Wherein, between described straight push rod 100 and described the first forming part 101, can carry out combination by screw 105 fixing.
Wherein, described straight push rod 100 can be two, so stressed comparatively stable.
Please, again in conjunction with consulting Fig. 6, Fig. 7, matched moulds state sectional structure schematic diagram, Fig. 7 that Fig. 6 illustrates as ejecting structure one preferred embodiment of the present utility model illustrate the die opening state sectional structure schematic diagram into ejecting structure one preferred embodiment of the present utility model.
During die sinking; described straight top ejects product 10 along die sinking direction; simultaneously described oblique top is along having oblique the exiting of angle at certain inclination angle with die sinking direction; after described the second forming part 103 exits back-off 11 completely (in order to ensure safety; conventionally also to exit again a safe distance more), can take out described product 10.Visible, said structure simple and can solve have circular-arc inner top surface and inner side have back-off 11 product 10 moulding and exit.
