Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for an automotive dashboard with auxiliary guide pillars. Background Technology

[0002] The car dashboard is a cockpit control interface that integrates core driving information such as speedometer, tachometer, fuel level, coolant temperature display, and malfunction warning lights. It enables human-vehicle interaction through mechanical pointers or digital displays. Because the production of automotive parts requires high precision, guide pillars are often used in molds to improve the accuracy of mold closing.

[0003] In existing injection molds used for automotive dashboard production, due to the large width of automotive dashboards, the main guide posts at the corners alone cannot ensure the accuracy of mold closing on the middle side of the moving mold, requiring the addition of auxiliary guide mechanisms. Furthermore, in existing molds, the auxiliary guide mechanisms have a fixed position where the guide sleeve acts on the guide rod. As the guide rod slides, the position of the guide sleeve cannot be concentrated in the middle section of the guide rod, thus failing to maintain the optimal guiding effect. Therefore, we propose an automotive dashboard injection mold with auxiliary guide posts. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an injection mold for an automotive dashboard with auxiliary guide pillars. This mold features a reliable moving mold guiding unit, with the main guide pillars playing a primary guiding role in the lifting and lowering of the mounting plate, ensuring accurate mold closing between the moving and fixed molds. After the moving mold extends into the base, it clamps with the fixed mold to form an arc-shaped cavity, thus producing an arc-shaped automotive dashboard that meets practical requirements. It also features a reliable auxiliary guiding unit, with the auxiliary guide pillars positioned between the left and right main guide pillars. These pillars provide guidance on the middle side of the wider mounting plate, further ensuring the smoothness of the lifting and lowering of the mounting plate. Furthermore, the springs on the upper and lower sides keep the mounting plate at the midpoint between the mounting plate and the upper surface of the base, allowing the sliding sleeve to consistently act on the middle section of the auxiliary guide pillars. This maintains a stable and effective guiding effect between the auxiliary guide pillars and the sliding sleeve, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for an automotive dashboard with auxiliary guide pillars, comprising a base, a moving mold guiding unit, and an auxiliary guiding unit;

[0006] Base: It has a rectangular structure and a fixed mold is fixedly connected inside. The upper end of the fixed mold has an arc-shaped structure.

[0007] Moving mold guiding unit: includes a top plate, main guide columns, lifting plate, guide sleeves and hydraulic cylinders. The top plate is horizontally set above the lifting plate. Four vertical main guide columns are installed between the top plate and the base. The upper and lower ends of the main guide columns are fixedly connected to the four corners of the top plate and the base, respectively. The lifting plate is horizontally set below the top plate, and a circular through hole is opened at each of the four corners of the lifting plate. A guide sleeve is fixedly installed at the upper end of each through hole. The main guide columns pass through the inside of the guide sleeves and are slidably connected to the guide sleeves. A hydraulic cylinder is fixedly installed in the middle of the upper end of the lifting plate. The telescopic end of the hydraulic cylinder faces upward and is fixedly connected to the lower side of the top plate.

[0008] Auxiliary guide unit: installed between the lifting plate and the base.

[0009] The top plate is used for the lifting of the hydraulic cylinder, which drives the lifting plate to move up and down. The lifting plate is used for the installation of the moving mold. The moving mold extends into the interior of the base and clamps with the fixed mold to form a mold cavity. The main guide column plays a major guiding role in the lifting of the lifting plate. Under the action of the guide sleeve, the sliding connection between the lifting plate and the main guide column can be made more stable, thereby ensuring that the moving mold and the fixed mold can be accurately closed.

[0010] Furthermore, the moving mold guiding unit also includes fixed feet and a moving mold. A fixed foot is installed at the middle position of each vertical side of the top plate, and the fixed feet are fixedly connected to the base. Vertical bolt through holes are provided inside the fixed feet. The lower end of the lifting plate is fixedly connected to the moving mold. The lower front end of the moving mold has an arc-shaped structure, and its curvature is equal to the curvature of the upper arc surface of the fixed mold. The fixed feet are used to install bolts, thereby fixing the top plate to the wall top or external frame. The arc-shaped surfaces of the moving mold and the fixed mold clamp the curved mold cavity, thus enabling the production of an arc-shaped automotive dashboard that meets actual requirements.

[0011] Furthermore, the auxiliary guiding unit includes auxiliary guide columns, sliding sleeves, and a linkage frame. Two auxiliary guide columns are fixedly connected to the lower ends of both the front and rear sides of the lifting plate. The auxiliary guide columns are vertically arranged, and their lower ends are slidably connected inside the base. The two auxiliary guide columns are symmetrically distributed left and right, and the distance between each auxiliary guide column and its adjacent main guide column is equal. The linkage frame is horizontally arranged, and two sliding sleeves are fixedly connected at the trisection points. The sliding sleeves are slidably connected to the outside of the auxiliary guide columns. The two corresponding main guide columns pass through the ends of the linkage frame and maintain a slidable connection with it. The linkage frame is used for installing the sliding sleeves, which are used to engage with the auxiliary guide columns, thereby achieving a sliding connection between the lifting plate and the auxiliary guide columns. The auxiliary guide columns provide auxiliary guidance in the middle section of the lifting plate, further ensuring the stability of the lifting plate's lifting and sliding.

[0012] Furthermore, the auxiliary guide unit also includes springs. A spring is fixedly connected to both the upper and lower sides of the linkage frame end. The springs are sleeved on the outside of the main guide column and respectively press against the lower side of the lifting plate and the upper side of the base. When the lifting plate is pressed down, it compresses the springs, causing the auxiliary guide column to insert downwards into the base. The springs on both sides ensure that the lifting plate is always at the midpoint between the lifting plate and the upper surface of the base, thus allowing the sliding sleeve to consistently act on the middle section of the auxiliary guide column, thereby maintaining the guiding effect of the auxiliary guide column and the sliding sleeve in a stable and optimal state.

[0013] Furthermore, it also includes lift-out rods, shaping grooves, and material delivery pipes. Six lift-out rods are fixedly connected to the arc surface on the lower front side of the moving mold. The six lift-out rods are distributed in a rectangular array and are horizontally facing forward. A fan-shaped shaping groove is opened at the front end of the moving mold. Two material delivery pipes are installed at the front end of the base. The material delivery pipes are fixedly connected to the base and communicate with the interior of the base. The upper end of the material delivery pipes is inclined upward. The material delivery pipes are used to pour injection molding material into the mold cavity. The shaping groove is used to form the groove structure for mounting the instrument panel on the car dashboard. The lift-out rods can lift the molded instrument panel product upward when the moving mold moves out, which facilitates pulling the product longitudinally forward after lifting out.

[0014] Furthermore, the moving mold guiding unit also includes mounting rods. Four mounting rods are circumferentially arrayed and fixedly connected to the upper end of the lifting plate, located at each circular through hole. Four corresponding slots are provided at the bottom seat of the guide sleeve, and the mounting rods are engaged in these slots. The mounting rods are used for the installation and positioning of the guide sleeves, ensuring that each guide sleeve is aligned with the circular through hole during installation, thus maintaining good sliding between the guide sleeve and the main guide post.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This automotive dashboard injection mold with auxiliary guide pillars has the following advantages:

[0016] 1. It has a reliable moving mold guiding unit. The main guide column plays the main guiding role in the lifting and lowering of the lifting plate, ensuring that the moving mold and the fixed mold can be accurately closed. After the moving mold extends into the interior of the base, it clamps with the fixed mold to form a mold cavity with an arc cross section, thereby enabling the production of arc-shaped car dashboards that meet actual needs.

[0017] 2. It also has a reliable auxiliary guide unit. The auxiliary guide column is set between the left and right main guide columns, which can play a guiding role in the middle side of the wider lifting plate, thereby further ensuring the smoothness of the lifting plate's lifting and sliding. In addition, the springs on the upper and lower sides can keep the lifting plate at the middle height between the lifting plate and the upper end of the base, so that the sliding sleeve can always act on the middle section of the auxiliary guide column, thereby keeping the guiding effect of the auxiliary guide column and the sliding sleeve stable and in a good state.
