Description

A servo core-pulling mechanism for an air chamber mold

technical field

The utility model relates to the technical field of moulds, in particular to a servo core-pulling mechanism of an air chamber mould.

Background technique

As shown in Figure 1, the air chamber A has a long barrel B, and the cylindrical mold core needs to be pulled out from the long barrel B when the mold is opened. The existing core-pulling method is to use an oil cylinder to pull the core, and the speed is not uniform, which leads to unstable demoulding at the core-pulling part of the mold, which easily causes damage to the inner wall of the long cylinder, and the product yield is low.

Utility model content

The technical problem to be solved by the utility model is to provide a servo core-pulling mechanism for an air chamber mold based on the deficiencies of the above-mentioned prior art, which can realize uniform-speed core-pulling and improve the yield of good products.

The technical scheme of the utility model is as follows:

A servo core-pulling mechanism for an air chamber mold, including a template, a mounting seat, a servo motor, a screw rod, a nut slider, and a cylindrical mold core; the center of the template is provided with a mold core, and the mounting seat is fixed on the template and is provided with a chute facing the mold core;

The screw rod is installed on the mounting seat through a bearing and is located in the chute, the nut slider is set in the chute and is threadedly connected with the screw rod, and the cylindrical mold core is set in the chute The nut slider;

The servo motor is connected to one end of the screw rod and drives the screw rod to rotate, so that the cylindrical mold core moves along the chute and moves in and out of the core part.

Further, positioning bosses and positioning steps are arranged on the front and back of the bottom of the mounting base, and positioning grooves are arranged on the top surface of the template; the positioning bosses are embedded in the positioning grooves, and the positioning steps are against the edge of the template , so that the mounting seat and the template are positioned.

Further, the installation seat is provided with a connection hole, and the template is provided with a threaded hole, and bolts pass through the connection hole to connect with the threaded hole, so that the installation seat is connected to the template.

Further, it also includes a limiting bead; a first limiting boss is provided on both sides of the inner wall of the chute, and a second limiting boss is arranged on both sides of the nut slider at the same height as the limiting boss ; The limiting bead is fixed on the first limiting boss, and the bottom surface of the limiting bead is against the top surface of the first limiting boss and the second limiting boss, thereby limiting the nut from sliding Blocks move up and down.

Further, a U-shaped frame is arranged on the side of the template, and the servo motor is installed on the U-shaped frame.

Compared with the prior art, the utility model has the following beneficial effects: (1) With the cooperation of servo motor, screw rod and nut slider, the mold can be molded by core-pulling at a uniform speed, effectively avoiding the Uneven speed causes damage to the inner wall of the long cylinder of the air chamber, which can effectively improve the stability of mold core pulling, ensure product quality, and increase yield; (2) This mechanism can reduce mold size and reduce mold development costs.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figure 2-3, the embodiment provided by the utility model is a servo core-pulling mechanism for an air chamber mold, including a template 10, a mounting base 20, a servo motor 30, a screw rod 40, a nut slider 50 and a cylindrical Core 60.

A mold core portion 11 is disposed at the center of the formwork 10 , and the mounting seat 20 is fixed on the formwork 10 and provided with a slide groove 21 facing the mold core portion 11 .

Positioning bosses 22 and positioning steps 23 are arranged on the front and back of the bottom of the mounting seat 20, and the top surface of the template 10 is provided with a positioning groove 12; The template 10 is positioned.

The mounting base 20 is provided with a connecting hole 24 , the template 10 is provided with a threaded hole 13 , and bolts (not shown in the figure) pass through the connecting hole 24 to connect with the threaded hole 13 , so that the mounting base 20 is connected to the template 10 .

The screw rod 40 is mounted on the mounting base 20 through a bearing and located in the slide groove 21 , the nut slider 50 is set in the slide groove 21 and is threadedly connected with the screw rod 40 , and the cylindrical mold core 60 is set on the nut slide block 50 .

As shown in FIG. 4 , this embodiment also includes a limiting bead 25 . Both sides of the inner wall of the chute 21 are provided with a first limiting boss 26, and both sides of the nut slider 50 are provided with a second limiting boss 51 equal in height to the limiting boss; the limiting bezel 25 is fixed on the first limiting boss. The boss 26, and the bottom surface of the limiting bead 25 abuts against the top surfaces of the first limiting boss 26 and the second limiting boss 51, thereby restricting the nut slider 50 from moving up and down.

A U-shaped frame 14 is arranged on the side of the template 10 , and the servo motor 30 is installed on the U-shaped frame 14 . The servo motor 30 is connected to one end of the screw mandrel 40 and drives the screw mandrel 40 to rotate, so that the cylindrical mold core 60 moves along the chute 21 and moves in and out of the mold core part 11 .

The above disclosures are only the preferred embodiments of the present utility model, which certainly cannot limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope of the present utility model.
