Description

Rocker arm structure sliding block for narrow space

Technical Field

The utility model belongs to an auxiliary forming mechanism of a hot-press forming die, and particularly relates to a rocker arm structure sliding block used in a narrow space.

Background

The core pulling is used for processing the position on a product parting surface where demoulding cannot be carried out, such as an inverted hook area on a forming surface, so that the core pulling belongs to an inverted hook processing system and is a structure of a mould. Core pulling definition: the mechanism for ensuring the smooth demoulding of the product is also called a sliding block. For example, in the area where some parts have barbs, after the mold is opened, if the core in the area of the barbs is not drawn out, the product cannot be ejected. At the moment, the mold structure adopts a slide block structure, the core in the region of the barb is made to be movable and is driven by a cylinder or an oil cylinder, and the movement is called core pulling. Core-pulling mechanisms are common mechanisms in molds. However, due to the special shape of some parts, the barb characteristic appears on the elevation of the convex shape. Due to the limitation of the space of the mold, if the conventional core pulling structure, namely the slide block, the slide block guide plate and the driving oil cylinder or the air cylinder, is adopted, the core pulling mechanism becomes very long, and no enough space is available for placing the structures, so that the core pulling mechanism which can not only meet the core pulling requirement but also can not increase the volume of the mold needs to be found.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical difficulties, the utility model aims to design a core pulling mechanism which can not only meet the core pulling requirement but also can not increase the volume of a mould.

The technical scheme provided by the utility model is as follows: the utility model provides a rocker arm structure slider for narrow and small space, includes actuating cylinder, and actuating lever front end in the actuating cylinder is fixed with U type connecting block, the U type inslot of U type connecting block articulates there is rocker arm structure, the structural slider that is fixed with of rocker arm, the slider inlays in the cover half benevolence, and the profile after combining with the benevolence profile of cover half is identical with mould product profile, actuating cylinder and the benevolence fixed connection of cover half, actuating cylinder is used for driving rocker arm structure.

Further optimization and improvement of the scheme are as follows: the rocking arm structure includes rocking arm and rocking arm upper end and rocking arm articulated movable block, the upper end and the lower extreme of rocking arm all are equipped with waist shape hole, the upper end and the movable block of rocking arm are articulated through waist shape hole, the lower extreme and the U type connecting block of rocking arm also are articulated through waist shape hole, the one side of rocking arm is kept away from at the movable block to the slider through bolted construction fixing. The waist-shaped hole is used for adjusting the up-and-down movement distance of the rocker arm so that the sliding block is just embedded into the cavity insert and can be replaced.

Further optimization and improvement of the scheme are as follows: the middle position of rocking arm is equipped with U type fixed block, the rocking arm articulates in the U type inslot of U type fixed block, U type fixed block passes through bolt construction to be fixed in the die core, die core internal fixation has the stop collar that suits with the slider, the slider embedding is in the stop collar. U type fixed block can further be with whole stable in structure in the narrow and small space of mould, the stop collar is spacing to the movement track of slider, prevents that it from shifting in the cover half benevolence to guarantee the shaping quality of mould.

Compared with the prior art, the utility model has the following beneficial effects: the utility model controls the movement of the sliding block through the rocker arm structure, thereby realizing demoulding, and having simple structure, ingenious design and strong popularization; in addition, the utility model fully utilizes the narrow space at the bottom of the fixed mold core and is actually a built-in core pulling structure, so that the volume of the mold is not increased, and the production cost is saved.

Detailed Description

The present invention is described in further detail below with reference to the accompanying drawings, which provide a specific fixed mold core embodiment, and specifically refer to fig. 2 to 4, and fig. 4 shows a specific application of the present invention in the fixed mold core embodiment. The application is detailed as follows:

as shown in fig. 1 to 4, a shown rocker arm structure slider for narrow and small space comprises a driving oil cylinder 1, a U-shaped connecting block 3 is fixed at the front end of a driving rod 2 in the driving oil cylinder, a rocker arm structure 4 is hinged in a U-shaped groove of the U-shaped connecting block 3, the rocker arm structure 4 comprises a rocker arm 41 and a movable block 42 with the upper end hinged to the rocker arm, waist-shaped holes 8 are arranged at the upper end and the lower end of the rocker arm, the upper end of the rocker arm 41 is hinged to the movable block through the waist-shaped holes 8, the lower end of the rocker arm 41 is hinged to the U-shaped connecting block through the waist-shaped holes 8, a slider 5 is fixed on the rocker arm structure 4, the slider 5 is fixed on one surface of the movable block 42 far away from the rocker arm through a bolt structure, the driving oil cylinder 1 is used for driving the rocker arm structure 4, before injection molding, after the driving oil cylinder is started, the driving rod 2 in the oil cylinder drives the rocker arm 41 to move towards the driving oil cylinder, thereby the slide block 5 positioned on the movable block 42 moves, finally the slide block 5 is embedded into the fixed die core 6 and combined with the missing part on the molded surface of the fixed die core 7, the combined molded surface is matched with the molded surface of a die product, a limit sleeve 9 matched with the slide block is fixed in the fixed die core 7, and the slide block 5 is embedded into the limit sleeve 9; after the injection molding is finished, the driving oil cylinder is started, the driving rod 2 positioned in the oil cylinder drives the rocker arm 41 to move in the reverse direction of the driving oil cylinder, so that the sliding block 5 embedded in the fixed mold core 6 is separated, the demolding of the complex molded surface is finished, and the operation is simple and stable. The driving oil cylinder 1 is fixedly connected with the fixed die core 6, in order to further fix the whole structure, a U-shaped fixing block 6 is arranged at the middle position of the rocker arm 41, the rocker arm 41 is hinged in a U-shaped groove of the U-shaped fixing block 6, and the U-shaped fixing block 6 is fixed in the fixed die core 7 through a bolt structure.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
