Description

Metal mold for manufacturing stabilizer bar bushes

The present invention relates to a mold apparatus for forming a stabilizer bar bush, and more particularly, a support fixture groove for accommodating a support body for forming a stabilizer bar bush, and a core fixture including a core having an incision groove inserted therein. A product forming block having a plurality of lower blocks spaced apart from each other, the space for accommodating the core and the support, and the upper portion that can be formed into a stabilizer bar bush by injecting rubber into the upper center of the core inserted into the space The present invention relates to a stabilizer bar bush molding apparatus for forming a block to prevent the stabilizer bar from bending during injection molding by preventing shaking while allowing the support and the core portion to be stably positioned in a stable position.

In general, the stabilizer bar bush refers to a bush in which the inner rubber of the inner steel is rotated as a stabilizer without slip so that noise caused by friction does not occur according to the roll motion of the vehicle.

In addition, since the vehicle tends to be inclined when driving at high speeds when the car curves at high speeds, a stabilizer bar is installed to maintain parallelism of the car. Both ends are coupled to a lower arm and the center is supported by a rubber bush and a bracket on the frame.

On the other hand, conventional integrated stabilizer bar bush is made in the form of molding by injecting rubber into the mold is inserted parts.

In addition, in order to assemble the stabilizer bar, the cutting direction is formed upward in a 45 ° direction with respect to the horizontal center line, so that automation is difficult when assembling, and the bushing is separated from the assembly bracket due to excessive compression between the inner steel and the assembly bracket. There is a problem that occurs.

The present invention has been made in order to solve the above problems, stably positioned in the lower block the support and the core portion accommodated inside the stabilizer bar bush, the product forming block and the upper block is filled by the injection pressure It is an object of the present invention to provide a mold bar forming device for stabilizer bar bushes that can support the support and the core by the rubber which is not shaken, thereby reducing the defect rate of the injection product and making the product uniform in quality.

In order to achieve the above object, the present invention relates to a mold apparatus for forming a stabilizer bar bush, and more particularly, a support fixing groove for receiving a support for forming a stabilizer bar bush, and a cutting groove. Stabilizer bar by inserting a rubber in the upper center of the core member inserted into the space portion, and the lower block is formed of a plurality of core member fixtures are inserted into the core material spaced apart, the space for accommodating the core material and the support; Stabilizer bar bush forming to prevent bush from bending during injection molding by preventing the shaking while the upper block is formed in the shape of bush to stably position the support and the core part in a stable position. The mold apparatus for this invention is related.

The present invention can stably position the support and the core portion accommodated inside the stabilizer bar bush in the lower block to improve the efficiency of the mold work and improve the adhesion of the solid parts and the rubber, as well as the parts at the same time Since it is inserted, there is a feature that can make a product of uniform quality.

In addition, the product forming block and the upper block are supported by holding the support and the core material not to be shaken by the rubber filled by the injection pressure, so that the defective rate of the injection product can be lowered and the quality can be formed into a uniform product.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, parts irrelevant to the description are omitted for simplicity of explanation, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part includes a certain component, this means that it may further include other components rather than controlling other components unless otherwise stated.

1 and 2, 4 and 6, the support fixing groove 11 and the cutting groove 21 for accommodating the support 14 formed integrally with the stabilizer bar bush 50, respectively, as shown in FIGS. The lower block 10 is formed with a plurality of core material fastener 12 portion is inserted into the core material 20 having a).

In addition, the lower side of the core 20 to be fitted to the core holder 12 is inserted into the fixing groove 15 formed on the surface of the lower block 10 can be fixed.

Here, the core member 20 can be stably fixed to the guide member 13 formed at one side of the core member 12 because the incision groove 21 formed in the core member 20 is assembled. have.

On the other hand, the left and right of the lower block 10, the guide bar 41 is protruded, the guide bar 41 may support the product forming block 30 as a whole.

Here, the guide bar 14 is configured to be inserted into each of the fixing holes 51 formed in the product forming block 30 to be fixed.

The core 20 and the support 14 are accommodated in the space 31 of the product forming block 30.

That is, the product forming block 30 and the upper block 40 is laminated step by step on the lower block 10 can be injection molded products.

On the other hand, the upper block 40 is filled with a rubber material in the space 31 of the product forming block 30, as shown in FIG.

At this time, the rubber material filled in the space 31 has a structure flowing in the upper center position between the inner diameter and the outer diameter of the pipe constituting the core material (20).

Therefore, the product forming block 30 is a configuration capable of separating the injection molded stabilizer bar bush 50 as shown in FIGS.
