The inner end of the front die pull rod is fixedly connected with the inner end of the rear die pull rod, the outer end of the front die pull rod and the outer end of the rear die pull rod are respectively provided with a countersunk head, the stripper plate extension block, the fixed die plate extension block and the movable die plate extension block are sequentially and movably sleeved on the front die pull rod and the rear die pull rod which are connected together, and a spring is arranged between the stripper plate extension block and the fixed die plate extension block. The utility model discloses but wide application has avoided the cold stub bar of three-plate mould to drop the card automatically and the problem of drawing on the spring in the many and not enough three-plate mould structure moulds in the stub bar, has advantages such as simple structure, with low costs, equipment, dismantlement convenience, efficient.
Description
Technical Field
The utility model relates to an injection mold especially relates to an external pull rod mechanism of injection mold.
Background
The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic articles, the opening sequence of the mold parting surfaces is controlled in order to meet the needs of the molding process. When the mold is provided with two mold parting surfaces, a certain sequence is required for opening according to the requirements of a molding process, and therefore, the mold opening sequence is often controlled by devices such as a mold opening sequence controller and a shutter, but the devices have the risk that a cold material head falls and is clamped on a pull rod and a spring, and the shutter causes defects on products.
Disclosure of Invention
An object of the utility model is to provide an external pull rod mechanism of injection mold that simple structure, with low costs, equipment, dismantlement are convenient, efficient.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to an external pull rod mechanism of an injection mold, which comprises a front mold pull rod, a rear mold pull rod, a stripper plate extension block, a fixed mold plate extension block, a movable mold plate extension block and a spring;
the inner end of the front die pull rod is fixedly connected with the inner end of the rear die pull rod, the outer end of the front die pull rod and the outer end of the rear die pull rod are respectively provided with a countersunk head, the stripper plate extension block, the fixed die plate extension block and the movable die plate extension block are sequentially and movably sleeved on the front die pull rod and the rear die pull rod which are connected together, and a spring is arranged between the stripper plate extension block and the fixed die plate extension block.
The stripper plate extension block, the fixed template extension block and the movable template extension block are respectively fixed on the side walls of the stripper plate, the fixed template and the movable template, and the stripper plate, the fixed template and the movable template are sequentially overlapped together.
After the scheme of the adoption, because the utility model discloses a take off flitch extension piece, fixed die plate extension piece, movable die plate extension piece are fixed respectively on taking off flitch, fixed die plate, movable die plate's lateral wall, but wide application in many and the not enough three-plate die structure mould in space of stub bar, avoided three-plate die cold stub bar to drop the card voluntarily and problem at the spring or on pulling, provide more material head spaces of getting for automatic production's manipulator, make the plastics product can automatic production completely, have simple structure, with low costs, the equipment, it is convenient to dismantle, advantages such as efficient.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 1, the utility model relates to an external pull rod mechanism of injection mold, including front mould pull rod 1, back mould pull rod 2, take off flitch extension block 3, fixed die plate extension block 4, movable die plate extension block 5, spring 6.
The inner end of the front mould pull rod 1 is fixedly connected with the inner end of the rear mould pull rod 2, countersunk heads 11 and 21 are arranged at the outer end of the front mould pull rod 1 and the outer end of the rear mould pull rod 2, the stripper plate extension block 3, the fixed mould plate extension block 4 and the movable mould plate extension block 5 are sequentially movably sleeved on the front mould pull rod 1 and the rear mould pull rod 2 which are connected together, and a spring 6 is arranged between the stripper plate extension block 3 and the fixed mould plate extension block 4.
As shown in fig. 2 and 3, the stripper plate extension block 3, the fixed die plate extension block 4, and the movable die plate extension block 5 are respectively fixed on the sidewalls of the stripper plate 10, the fixed die plate 20, and the movable die plate 30, and the stripper plate 10, the fixed die plate 20, and the movable die plate 30 are sequentially stacked together.
The utility model discloses a theory of operation:
as shown in fig. 4, when the mold is opened, under the action of opening the mold of the injection molding machine, the spring 6 springs the stripper plate 10 and the fixed mold plate 20 through the stripper plate extension block 3 and the fixed mold plate extension block 4, and the separation distance is 82 mm;
as shown in fig. 5, after the runner plate 40 and the stripper plate 10 are opened by 6mm, the runner 50 automatically falls;
as shown in fig. 6, the fixed mold plate 20 and the movable mold plate 30 are opened by 150mm, and a product is taken out to complete a molding cycle.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
