Description

Technical Field

[0001] This utility model relates to the field of injection molding technology for new energy vehicle products, specifically to a mold structure for a suspended insert-type encapsulation of injection molding parts for new energy vehicle products. Background Technology

[0002] The suspended insert encapsulation mold is a mold structure specifically designed for injection molding of new energy automotive products. It is mainly used to precisely encapsulate metal inserts or other material inserts inside plastic parts.

[0003] Traditional plastic-coated inserts for new energy vehicles present several problems: First, positioning accuracy is an issue. During the high-temperature, high-pressure injection of molten plastic, inserts are highly susceptible to impact forces, leading to positional shifts or tilting, thus affecting the dimensional accuracy and functionality of the final product. Second, bonding strength is a problem. The bond between smooth metal inserts and plastic parts relies primarily on shrinkage forces. Under the complex conditions of high pressure and high vibration in automobiles, delamination, loosening, and even detachment can easily occur, failing to meet stringent performance requirements. Third, product quality defects are common. The plastic-coated interface often exhibits defects such as bubbles and shrinkage cavities due to uneven injection molding and inadequate sealing. These defects not only affect the product's appearance but also become stress concentration points, reducing its mechanical properties. To address these issues, this invention aims to provide a mold structure for the suspended placement of plastic-coated inserts in injection-molded parts for new energy vehicles, thereby solving these technical challenges. Utility Model Content

[0004] The purpose of this invention is to provide a mold structure for the suspended placement of inserts in injection molded parts of new energy vehicles, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold structure for a suspended placement of inserts for injection-molded parts of new energy vehicle products, including a support frame and a processing structure, wherein the processing structure is installed on the outer side of the support frame;

[0006] The processing structure includes a second electric cylinder, a first module, and a liquid injection pipe. The second electric cylinder is installed on the left side of the support frame, and the right side of the second electric cylinder passes through the support frame and connects to the first module. Liquid injection pipes are installed on both sides above the first module, and the liquid injection pipes are located inside the positioning groove. The positioning groove is located inside the second module. A third module is located below the second module. The right side of the first module is located between the second and third modules. The right side of the first module has two slots, and the slots contain locking blocks. A threaded post is installed on one side inside the locking block. Multiple locking posts are installed above the third module. Threaded metal inserts are installed on the outer walls of the threaded posts and the outer walls of the slots.

[0007] Preferably, the support frame is U-shaped, and the output end of the second electric cylinder is fixedly connected to the first module.

[0008] Preferably, the first module is fixedly connected to the injection tube, and the first module and the card slot are integrated into one unit.

[0009] Preferably, the card slot is L-shaped, and the card slot and the card block are correspondingly arranged.

[0010] Preferably, the locking block and the threaded post are arranged perpendicularly to each other, and the threaded post and the threaded metal insert are connected by threads.

[0011] Preferably, the locking pin and the third module are fixedly connected, and a sealing ring is installed on the outer wall of the threaded metal insert.

[0012] Preferably, the locking post and the threaded metal insert are correspondingly arranged, and the outer wall of the threaded metal insert is equipped with toothed blocks.

[0013] Preferably, the positioning groove and the second module are integrated, and the first electric cylinder is installed on the top of the second module.

[0014] Preferably, the distance between the third module and the support frame remains unchanged.

[0015] Preferably, the right side of the first module is correspondingly positioned with respect to the positioning slot and the third module.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] The threaded metal insert is fixed to the outside of the threaded column by a threaded connection. The locking block is rigidly engaged with the L-shaped locking groove, so that the threaded metal insert is suspended in the air, avoiding positional displacement caused by contact with the mold cavity. The L-shaped locking groove is longitudinally limited, and together with the locking structure of the locking block, it improves the pull-out resistance of the threaded metal insert and eliminates the risk of falling off under injection pressure.

[0018] A sealing ring is set at the mating point between the threaded metal insert and the locking post to block the overflow channel of molten plastic, avoid the formation of bubbles and shrinkage cavities at the plastic coating interface, and ensure that the molten plastic completely encapsulates the threaded metal insert. Furthermore, the toothed blocks on the outer wall of the threaded metal insert form a mechanical interlock with the plastic, and the molten plastic completely fills the tooth groove, thereby enhancing the plastic's biting force and improving its pull-out resistance.

[0028] Please see Figure 1-4 This utility model provides a mold structure technical solution for the suspended placement of inserts for injection molding parts of new energy vehicles: The mold structure for the suspended placement of inserts for injection molding parts of new energy vehicles includes a support frame 1 and a processing structure 2, with the processing structure 2 installed on the outside of the support frame 1.

[0029] The processing structure 2 includes a second electric cylinder 201, a first module 202, and an injection pipe 203. The second electric cylinder 201 is installed on the left side of the support frame 1. The right side of the second electric cylinder 201 passes through the support frame 1 and is connected to the first module 202. The injection pipes 203 are installed on both sides above the first module 202. The injection pipes 203 are located inside the positioning groove 204. The positioning groove 204 is located inside the second module 205. A third module 206 is located below the second module 205. The right side of the first module 202 is located between the second module 205 and the third module 206. Two slots 207 are located on the right side of the first module 202. A block 208 is located inside the slot 207. A threaded post 209 is installed on one side inside the block 208. Multiple posts 211 are installed above the third module 206. Threaded metal inserts 210 are installed on the outer wall of the threaded post 209 and the outer wall of the slot 207.

[0030] The support frame 1 is U-shaped and provides the main support frame for the entire mold. The output end of the second electric cylinder 201 is fixedly connected to the first module 202.

[0031] The first module 202 is fixedly connected to the injection pipe 203, which is used as a channel for injecting molten plastic. The first module 202 and the slot 207 are integrated.

[0032] The slot 207 is L-shaped, and the slot 207 and the block 208 are correspondingly set. The L-shaped slot 207 and the threaded locking structure enable the insert to be accurately suspended, avoiding displacement during injection molding.

[0033] The locking block 208 and the threaded post 209 are set perpendicular to each other, and the threaded post 209 and the threaded metal insert 210 are connected by threads.

[0034] The locking post 211 is fixedly connected to the third module 206, and a sealing ring is installed on the outer wall of the threaded metal insert 210.

[0035] The locking post 211 and the threaded metal insert 210 are correspondingly arranged, and the outer wall of the threaded metal insert 210 is equipped with toothed blocks.

[0036] The positioning groove 204 and the second module 205 are integrated, and the first electric cylinder is installed on the top of the second module 205.

[0037] The distance between the third module 206 and the support frame 1 remains unchanged.

[0038] The right side of the first module 202 is correspondingly set with the positioning slot 204 and the third module 206.

[0039] Working principle:

[0040] First, the threaded metal insert 210 is fitted onto the outside of the locking post 211 of the third module 206 and fixed to the outer wall of the threaded post 209 of the locking block 208 by threaded connection. Then, the locking block 208 with the threaded metal insert 210 assembled is inserted into the locking groove 207 of the third module 206 to achieve the suspension and positioning of the threaded metal insert 210.

[0041] Next, the second electric cylinder 201 is activated to push the first module 202 to the right, so that its right side is embedded inside the third module 206. Then the first electric cylinder above the second module 205 is activated to drive the second module 205 to move downward, so that the first module 202, the second module 205 and the third module 206 are closed to form a sealed cavity that matches the shape of the product. The threaded metal insert 210 is suspended in a preset position inside the cavity.

[0042] Then, molten plastic is injected into the cavity through the injection tube 203 to cover the threaded metal insert 210. After cooling and solidification, it forms an integral part, and the toothed blocks on the outer wall of the threaded metal insert 210 enhance the mechanical interlocking force with the plastic.

[0043] Finally, the second electric cylinder 201 and the first electric cylinder are reset synchronously, causing the first module 202 to move to the left and the second module 205 to move upward. After the mold is opened, the product remains above the third module 206. The rotating block 208 causes the threaded post 209 to separate from the threaded metal insert 210, releasing the suspension constraint. The product is then taken out upward, and the threaded metal insert 210 separates from the post 211, ultimately remaining inside the product to complete the plastic coating process.

[0044] Although embodiments of the present utility 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 utility, the scope of which is defined by the appended claims and their equivalents.
