Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for automotive parts. Background Technology
[0002] As an indispensable means of transportation, automobiles are composed of many parts during the production process, many of which are injection molded.
[0003] Some existing automotive parts have complex structures, such as components with metal inserts, plastic brackets with threaded inserts, and sensor housings with wires. Current technology usually requires pre-embedding the inserts in a mold, injection molding, removing the workpiece, and then transferring it to another mold for secondary injection molding or subsequent processing. This process is cumbersome, the inserts are prone to displacement, and production efficiency is low. At the same time, some parts do not require secondary injection molding during production, making it impossible to perform surface treatment on the workpiece after one injection molding in a timely manner. This results in the inability to complete multiple processing steps within a production cycle, leading to complex logistics, large cumulative errors, and high energy consumption.

[0027] This invention provides an injection mold for automotive parts, replacing traditional injection molds for automotive parts, thus avoiding the problems of complex processing procedures and low processing efficiency.
[0028] Figures 1-5 The diagram shown is a structural schematic of an injection mold for an automotive part according to this utility model. Please refer to [link / reference]. Figures 1-5 This section provides a detailed introduction to the injection molds for this type of automotive part.
[0029] Example 1
[0030] refer to Figures 1-5 This utility model discloses an injection mold for automotive parts, the main body of which includes an adaptive base 100, a rotating fixed mold mechanism 200 and a positioning moving mold mechanism 300.
[0031] The adaptive base 100 has multiple stations on top and has a first state for secondary injection molding of the injection molded workpiece and a second state for surface treatment of the injection molded workpiece, which facilitates adjustment according to production needs.
[0032] The rotary fixed mold mechanism 200 is installed in the adaptive base 100. The rotary fixed mold mechanism 200 includes a first mounting plate 210 with a plurality of fixed mold seats 210a evenly distributed on the bottom and a drive assembly 220 that drives the first mounting plate 210 to rotate intermittently. When working, the drive assembly 220 drives the plurality of moving mold seats 310a to rotate intermittently and then dock with the plurality of workstations, thereby performing multiple processes simultaneously.
[0033] The positioning moving mold mechanism 300 is installed above the adaptive base 100. The positioning moving mold mechanism 300 includes a second mounting plate 310 with multiple moving mold bases 310a at the bottom and a drive cylinder 320 for driving the second mounting plate 310 to move up and down. When working, the drive cylinder 320 drives the multiple moving mold bases 310a to move up and down, thereby cooperating with the corresponding fixed mold base 210a to complete mold closing or mold opening.
[0034] In this embodiment, the specific usage process is as follows: when the generated workpiece needs to be injected a second time, the adaptive base 100 is switched to the first state; when the produced workpiece does not need to be injected a second time and needs to be surface treated in time, the adaptive base 100 is switched to the second state. Then, the drive component 220 drives the fixed mold base 210a to rotate once, and the cylinder drives the moving mold base 310a to complete one descent and rise operation, thereby performing synchronous operation on multiple workstations.
[0035] Example 2
[0036] Based on Embodiment 1, the adaptive base 100 includes a support base 110, a first station 120, a second station 130, a third station 140 and a fourth station 150, with each station evenly distributed on the top surface of the support base 110. The top of the support base 110 is provided with a mounting bracket 110a for easy installation of the drive cylinder 320.
[0037] In this embodiment, when the adaptive base 100 is in the first state, the first station 120 is the insert installation station, the second station 130 is equipped with a primary injection head, the third station 140 is equipped with a secondary injection head, and the fourth station 150 is the cooling and unloading station. Thus, during the gap when the drive assembly 220 drives the first mounting plate 210 to rotate, the first station 120 performs insert installation, the second station 130 performs the first injection molding on the previous insert, the third station 140 performs a secondary injection molding on the workpiece after the first injection molding, and the fourth station 150 cools and unloads the workpiece after injection molding.
[0038] In this embodiment, when the adaptive base 100 is in the second state, a surface treatment component is provided on the third station 140. Other station processes are inconvenient. The third station 140 performs surface treatment on the workpiece after the first injection molding. The surface treatment component includes an integrated micro-needle valve spraying or plasma treatment module to perform micro-coating treatment (such as anti-scratch, anti-reflection) or activation treatment on the surface of the molded product to prepare for subsequent bonding.
[0039] In this embodiment, the drive assembly 220 includes a transmission gear 220a connected to the bottom of the first mounting plate 210 via a rotating shaft, a drive motor 220b located inside the support base 110, and a drive gear 220c located at the output end of the drive motor 220b and meshing with the transmission gear 220a. The number of teeth of the drive gear 220c is one-quarter of the number of teeth of the transmission gear 220a. When the transmission gear 220a rotates, it drives the first mounting plate 210 to rotate. When the drive motor 220b is working, it drives the drive gear 220c to rotate. When the drive gear 220c rotates, it drives the transmission gear 220a to rotate intermittently.
[0040] In this embodiment, tapered guide holes are provided at the top four corners of the fixed mold base 210a, and tapered guide rods are provided at the bottom four corners of the moving mold base 310a. The tapered guide holes and tapered guide rods cooperate to facilitate the positioning of the moving mold base 310a and the fixed mold base 210a during the mold closing process. In this process, the tapered design also helps the guide rod to enter the guide hole in advance when the shaft cores of the moving mold base 310a and the fixed mold base 210a are not completely aligned at the beginning. As the guide rod continues to descend, it pulls the multiple fixed mold bases 210a on the entire first mounting plate 210 back to the position where they are completely aligned with the moving mold base 310a. At this time, the sawtooth of the transmission gear 220a is separated from the sawtooth on the drive gear 220c, which does not affect the slight reverse rotation of the transmission gear 220a when the first mounting plate 210 is slightly reversed for precise positioning.
[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
