Abstract

The utility model provides a slide design ejection mechanism for an injection mold of a multi-reinforcing-rib device. A slide is not easy to cause products to strain or deform during the core pulling, so the size precision of products is ensured. The technical scheme is that the slide design ejection mechanism comprises a male die slide base, a locking block, a side draw pin, a slide thimble, a female die, and a male die core. During the die assembly, the slide thimble penetrates the male die core and has one end aligned to the end of the male die core and the other end arranged at the locking block in an ejection manner. The female die and the male die core are in fit arrangement to form an injection cavity. The male die core is tightly connected with the male die slide base. The side draw pin is tightly connected with the locking block and has a head arranged in a guide groove of the male die slide base. The slide design ejection mechanism is characterized in that the quantity of the slide thimble is equal to that of the multi-reinforcing-rib device, and the position where the other end of the slide thimble is arranged at the locking block in the ejection manner is a plane which is vertical to the movement direction of the locking block.

Description

A kind of row position design ejecting mechanism of injection mould of many reinforcements device

Technical field

The utility model relates to the ejecting mechanism technical field of injection mould mould, is specially a kind of row position design ejecting mechanism of 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 utility model provides a kind of row position design ejecting mechanism of injection mould of many reinforcements device, and 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 utility model, 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 utility model under the matched moulds state;

Fig. 2 is the structural representation of front view of the present utility model under die opening state.

The specific embodiment

See Fig. 1, Fig. 2, the utility model comprises 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 utility model 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.
