Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive overmolding mold technology, specifically a pneumatic automatic ejector mold for automotive overmolding. Background Technology
[0002] Automotive overmolding molds are molds specifically designed for manufacturing automotive parts, which are typically made by combining a metal framework with polymer materials. These molds are designed to achieve efficient and precise production processes to meet the demands of the modern automotive industry for complex shapes and high-performance materials.
[0003] After the existing automotive overmolding molds have completed injection molding and heating, the mold removal and unloading of the automotive overmolding parts are usually done manually. Manual operation is often unstable and prone to errors. These errors may not only damage the mold but also affect the molded automotive overmolding parts, thereby affecting product quality and production efficiency. At the same time, manual intervention limits the overall production efficiency. In today's manufacturing environment that pursues high efficiency and automation, relying on manual operation obviously cannot meet the ever-increasing production demands. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a pneumatic automatic ejector mold for molding automotive overmolded parts includes a mold base 1. Four support columns 3 are fixedly connected to the top of the mold base 1. A mold base plate 2 is fixedly connected between the tops of the four support columns 3. Two first side plates 7 and two second side plates 8 are disposed on the top of the mold base plate 2. A mold top plate 11 is disposed between the tops of the two first side plates 7 and the two second side plates 8. An injection pipe 12 is fixedly connected to the top of the mold top plate 11, and the output end of the injection pipe 12 passes through the mold top plate 11. A displacement assembly is disposed between the mold base 1 and the mold base plate 2. The displacement assembly is used to move the two first side plates 7 and the two second side plates 8. The top of each of the first side plates 7 and the two second side plates 8 is provided with positioning holes 9. The bottom of the mold top plate 11 is fixedly connected with a positioning rod 10, one end of which extends into the interior of the positioning hole 9. The two first side plates 7 are fixedly connected with a first sealing edge 13 on the side that is close to each other, and the two second side plates 8 are fixedly connected with a second sealing edge 14 on the side that is close to each other. The top of the mold bottom plate 2 is fixedly connected with a sealing bottom edge 16, and the side of the mold top plate 11 that is close to the mold bottom plate 2 is fixedly connected with a sealing top edge 15. The first side plate 7 and the two second side plates 8 are provided with inclined structures on both sides, and the inclined structures on both sides of the first side plate 7 fit together with the inclined structures on both sides of the second side plate 8.
[0021] When molding automotive overmolded parts, the two first side plates 7 and two second side plates 8 are first driven to move closer to each other using a displacement assembly, so that the inclined structures on both sides of the first side plate 7 fit with the inclined structures on both sides of the second side plate 8. Then, one end of the positioning rod 10 is aligned with the positioning hole 9 on the top of the first side plate 7 and the second side plate 8 and extends into the interior of the positioning hole 9. This allows the two first side plates 7, the two second side plates 8, the mold base plate 2, and the mold top plate 11 to form a closed molding environment for automotive overmolded parts under the combined action of multiple sealing edges. Then, the raw material is injected using the injection pipe 12, and then heated and molded by an external heater. Ideally, when removing the mold, the mold top plate 11 should be manually removed first. Then, under the action of the displacement assembly, the two side plates move away from each other, thereby achieving automatic material discharge after the automotive overmolded parts are molded, which makes it convenient for workers to pick up and collect the finished products.
[0022] like Figures 1-4 As shown, the displacement assembly includes a cross-shaped air pump 4, which is fixedly installed between the mold base 1 and the mold base plate 2. Each of the four output ends of the cross-shaped air pump 4 is fixedly connected to a connecting block 5, and each of the four connecting blocks 5 is fixedly connected to a sliding rod 6. The tops of the four sliding rods 6 are respectively fixedly connected to two first side plates 7 and two second side plates 8. Four sliding grooves 17 are opened on the outer side of the mold base plate 2, and the four sliding rods 6 are slidably connected to the inner walls of the four sliding grooves 17 respectively.
[0023] The connecting block 5 is moved by the cross air pump 4, which causes the slide rod 6 on the top of the connecting block 5 to move inside the slide groove 17. This pushes the corresponding side plate to the corresponding position according to the usage requirements, thereby facilitating the rapid construction of a closed molding environment for automotive rubber-coated parts and improving the production efficiency of automotive rubber-coated parts.
[0024] This utility model provides a pneumatic automatic mold ejection system for automotive overmolded parts. The specific working principle is as follows: During the molding of automotive overmolded parts, a cross-shaped air pump 4 first drives a connecting block 5 to move, causing the sliding rod 6 at the top of the connecting block 5 to move inside the sliding groove 17. This pushes the two first side plates 7 and two second side plates 8 closer together according to usage requirements, so that the inclined structures on both sides of the first side plate 7 and the inclined structures on both sides of the second side plate 8 fit together. Then, one end of the positioning rod 10 is aligned with the positioning holes 9 at the top of the first side plate 7 and the second side plate 8 and extends into the interior of the positioning holes 9. This allows the two first side plates 7, the two second side plates 8, the mold base plate 2, and the mold top plate 11 to form a closed molding environment for automotive overmolded parts under the combined action of multiple sealing edges. Then, the raw material is injected through the injection pipe 12, and then heated and molded using an external heater. Ideally, when removing the mold, the mold top plate 11 should be manually removed first. Then, the cross-shaped air pump 4 drives the two side plates away from each other, thereby achieving automatic ejection of the molded automotive overmolded parts.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
