Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold for an automobile column interior trim panel. Background Art

[0002] The injection mold for the interior trim of the automobile pillar is a mold used to produce the interior trim of the automobile, especially the injection mold for the interior trim of the automobile B-pillar and the door pillar. The design and manufacture of this mold involve multiple technical aspects to ensure the accurate molding and high-quality production of the interior trim. The special injection mold for the interior trim of the automobile door pillar involves an upper mold body and a lower mold body. The upper mold body is provided with an inclined top and a straight top rod for restraining the seat belt sliding hole, and the lower mold body is provided with a top hole corresponding to the straight top rod. This design can prevent the seat belt sliding hole from deforming. The positioning effect of the straight top rod during the demoulding process prevents the surrounding structure from squeezing into the seat belt sliding hole and causing deformation. The application of these injection molds is not limited to traditional automobile manufacturing, but also with the development of electric vehicles, unmanned driving technology and new energy With the development of the automobile era, lightweight automobile design has become a trend, and the injection mold for automobile column interior panels has increased in size and weight. The common automobile column interior panel injection molds on the market are usually connected to the lifting ring through a wire rope during hoisting and mobile installation. The connection is cumbersome and easy to slip, posing a safety hazard. In the process of closing the injection mold, the guide column is plugged in and positioned at the first time, and the positioning sleeve mounted on the outside of the guide column will be subject to greater wear and tear, requiring frequent maintenance or replacement. However, when replacing the positioning sleeve, the top of the upper mold body needs to be disassembled, which is cumbersome to replace and affects efficiency. Frequent disassembly of the mold will also affect precision and service life. When the injection molded parts are taken out, if the operation is improper, it is easy to cause residue or deformation of the injection molded parts, affecting the yield rate.

[0008] The present invention provides an injection mold for an automobile column interior trim panel, which has the following beneficial effects:

[0009] When the lower mold body, the upper mold body and the base structure are moved and installed together during hoisting, the wire rope can be controlled to be inserted into the embedded groove to control the wire rope connection.

The guide column is inserted into the inside of the guide sleeve to assist the guide sleeve in positioning. After the guide sleeve is subjected to force, the guide sleeve can squeeze the spring inside the kit and eliminate the collision force with the help of the elasticity of the spring. At the same time, after the inside of the guide sleeve is greatly worn, the tool can be controlled to be inserted into the inside of the insertion groove without disassembling the upper mold body, and the guide sleeve can be controlled to rotate so that the connecting head is detached from the inside of the fixed head component with the help of the thread, so that the guide sleeve can be easily disassembled and replaced, and the worn guide sleeve can be replaced without disassembling the upper mold body.

[0011] After the injection molding is completed, if the temperature of the injection molded part is high or the material is not completely returned, you can use a dust-blowing paint spray gun inserted into the inside of the jack to allow air to pass through the inside of the internal part, the inside of the mounting assembly and the inside of the connecting hole, so that the airflow is evenly sprayed out through the inner end of the connecting hole, so that the fast-flowing airflow contacts the injection molded part, and the airflow assists in heat dissipation of the injection molded part. At the same time, with the help of the impact force of the airflow, the injection molded part is evenly forced to rise and be taken out, avoiding manual removal of the injection molded part, which may cause damage or deformation of the injection molded part.

[0033] Embodiment 2, based on embodiment 1, a one-way upward flipping closing plate can be installed at the end of the branch hole of the connecting hole 101 to prevent liquid from entering the branch hole and clogging it during injection molding. When air enters, the closing plate can be automatically pushed up and flipped open.

[0034] The working principle of this embodiment is as follows: when it is necessary to perform injection molding on the interior trim of the automobile column, the steel wire rope can be first controlled to be inserted into the inside of the embedding groove 302, and then the steel wire rope can be controlled to be fixedly connected. With the help of the lifting equipment and the steel wire rope, the lower mold body 1 is controlled to be forced to rise, and the steel wire rope contacts the force-bearing structure 304, pushing the force-bearing structure 304 to rise, and the anti-skid groove of the force-bearing structure 304 contacts the steel wire rope in an anti-skid manner, and the force-bearing structure 304 drives the pulling head 305 to rise together, and the pulling head 305 rises inside the sliding groove 307. Due to the contact The surface is an inclined structure, so that the push plate structure 306 is forced to move horizontally, driving the plug plate structure 308 to move horizontally together. The plug plate structure 308 clamps and fixes the wire rope through the V-shaped groove to improve the fixing effect of the wire rope, avoid sliding when the lower mold body 1 is hoisted, and increase the safety hazard. Then control the installation and connection of the lower mold body 1, the upper mold body 2 and the base structure 3, control the pipeline connection, and when injection molding is required, first clean the injection molding groove, and then control the upper mold body 2 to move above the lower mold body 1, so that the guide column 108 is inserted into the interior of the guide sleeve 206. When the guide sleeve 206 contacts the guide sleeve 206, if it encounters a collision, the spring inside the kit 204 can be squeezed, and the collision force can be eliminated with the help of the elasticity of the spring. If the guide sleeve 206 is worn after being used many times, the tool can be controlled to be inserted into the interior of the insertion groove 208, so that the guide sleeve 206, the kit 204 and the connector 203 rotate together, and the upper mold body 2 can be disassembled through the thread, so that the guide sleeve 206 can be replaced without disassembling. After the upper mold body 2 is closed, the interior trim panel is injection molded. After the injection molding is completed, the upper mold body 2 rises, and the jet gun can be controlled to be inserted into the interior of the jack 105, so that the airflow of the jet gun enters the interior of the connecting hole 101 for circulation, and the airflow is ejected through the sub-holes. The airflow is evenly ejected through the inner end of the connecting hole 101, so that the fast-flowing airflow contacts the injection molded part, and the airflow assists in heat dissipation of the injection molded part. At the same time, with the help of the impact force of the airflow, the stuck injection molded part is evenly forced to rise and be taken out, avoiding manual removal of the injection molded part, which causes damage or deformation of the injection molded part.
