Abstract
The invention provides a line-bit design ejector mechanism of an injection die of a multi-reinforcing-rib device. The line bit protects a product from being damaged by pulling or deformed in a core-loosing process and ensures the size accuracy of the product. The invention adopts the technical scheme that the line-bit design ejector mechanism of the injection die of the multi-reinforcing-rib device comprises a terrace die line-bit seat, a locking block, an inclined guide post, line-bit thimbles, a cavity die and a terrace die insert. In die assembly, each line-bit thimble penetrates through the terrace die insert, one end pat of the line-bit thimble is level to the end part of the terrace die insert, and the other end part of the line-bit thimble abuts against the locking block, the cavity die and the terrace die insert are matched and mounted to form an injection cavity, the terrace die insert is tightly connected with the terrace die line-bit seat, the inclined guide post is tightly connected with the locking block, and the head of the inclined guide post is mounted in a guide rail groove of the terrace die line-bit seat. The line-bit design ejector mechanism of the injection die of reinforcing-rib the multi-reinforcing-rib device is characterized in that the number of the line-bit thimbles is equal to the number of reinforcing ribs of the multi-reinforcing-rib device, the position where the other end of each line-bit thimble abuts on the locking block is a plane, and the plane is perpendicular to the motion direction of the locking block.
Description
Technical field
The present invention relates to the ejecting mechanism technical field of injection mould mould, be specially the row position design ejecting mechanism of the injection mould of many reinforcements device.
Background technology
The last moulding of need being expert at of existing many reinforcements device, its reinforcing rib structure, the row position is pulled product or cause distortion easily in the process of loosing core, influence the product size precision.
Summary of the invention
At the problems referred to above, the invention provides the row position design ejecting mechanism of the injection mould of many reinforcements device, the row position is difficult for distortion is pulled or caused to product in the process of loosing core, and has guaranteed dimensional accuracy of products.
Its technical scheme is such: it comprises the capable position of punch seat, latch segment, Angle Pin, row position thimble, die, the punch die, described row position thimble during matched moulds runs through described punch die, the one end is mutually concordant with described punch die end, its the other end is mounted on described latch segment, described die, described punch die cooperates installs the formation injection molding cavity, described punch die is fastenedly connected the capable position of described punch seat, described Angle Pin and described latch segment are fastenedly connected, the head of described Angle Pin is loaded on the guide-track groove of the capable position of described punch seat, it is characterized in that: the quantity of described row position thimble equals the reinforcement quantity of many reinforcements device, the position of the described latch segment of the other end top dress of described row position thimble is the plane, and described plane is perpendicular to the direction of motion of described latch segment;
It is further characterized in that: described row position thimble be axially installed with spring, the contact position of described punch capable position seat and described die is equipped with the compression spring.
In the said structure of the present invention, the position that the other end of row position thimble is supported on latch segment is the plane, the plane is perpendicular to the direction of motion of latch segment, row position thimble ejects the product that injection moulding is finished from the punch die, finish and loose core, row position is difficult for product pulled or cause distortion in the process of loosing core, guaranteed dimensional accuracy of products, thereby avoided in the prior art, a reinforcing rib structure last moulding of need being expert at, the row position is pulled product or cause distortion easily in the process of loosing core, influence the product size precision.
Description of drawings
Fig. 1 is the structural representation of front view of the present invention under the matched moulds state;
Fig. 2 is the structural representation of front view of the present invention under die opening state.
The specific embodiment
See Fig. 1, Fig. 2, the present invention includes the capable position of punch seat 1, latch segment 2, Angle Pin 3, row position thimble 4, die 5, punch die 6, row position thimble 4 during matched moulds runs through punch die 6, thimble 4 one ends, row position are mutually concordant with punch die 6 ends, the other end of row position thimble 4 is mounted on latch segment 2, die 5, punch die 6 cooperates installs formation injection molding cavity 7, punch die 6 is fastenedly connected the capable position of punch seat 1, Angle Pin 3 is fastenedly connected with latch segment 2, the head of Angle Pin 3 is loaded on the guide-track groove 8 of the capable position of punch seat 1, the quantity of row position thimble 4 equals the reinforcement quantity of many reinforcements device, the position that the other end of row position thimble 4 is supported on latch segment 2 is the plane, and the plane is perpendicular to the direction of motion of latch segment 2; Row position thimble 4 be axially installed with spring 9, the capable position of punch seat 1 is equipped with compression spring 10 with the contact position of die 5.The moving direction of latch segment 2 when the arrow among Fig. 2 is die sinking.
11 is 12 for the capable position of punch seat wearing plate among latch segment wearing plate, the figure among the figure.
Below in conjunction with accompanying drawing the course of work of the present invention is described: after the mold-closing injection, one end of all row position thimbles 4 heads on the corresponding reinforcement of the many reinforcements device in the injection molding cavity 7 respectively, during die sinking, direction in the time of only need allowing latch segment 2 deviate from its matched moulds moves, make Angle Pin 3 withdraw from the guide-track groove 8 of the capable position of punch seat 1 gradually, because the existence of gradient, the capable position of punch seat 1 can be gradually away from die 5 as can be known according to the principle of similar triangles, punch die 6 is also away from die 5 simultaneously, at this moment, because it is the plane that the other end of row position thimble 4 is supported on the position of latch segment 2, the plane is perpendicular to the direction of motion of latch segment 2, promptly in the whole process that latch segment 2 moves, as long as row position thimble 4 still is supported on the plan-position of latch segment 2, row position thimble 4 can not be moved, position when the one end still is positioned at its matched moulds, because punch die 6 is away from die 5, row position thimble 4 ejects the product that injection moulding is finished from punch die 6, finish and loose core, the row position is difficult for distortion is pulled or caused to product in the process of loosing core, and has guaranteed dimensional accuracy of products.Row position thimble 4 be axially installed with spring 9, guarantee that row position thimble 4 can not be moved, and the contact position of the capable position of punch seat 1 and die 5 is equipped with compression spring 10, when matched moulds, compression spring 10 is in compressive state, compression spring 10 forces in the capable position of punch seat 1 for the shape that resiles when die sinking.
