Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a demolding mechanism for an automotive water tank. Background Technology

[0002] In the automotive manufacturing industry, the radiator is a key component of the vehicle's cooling system, and the efficiency and reliability of its production are of paramount importance. Automotive radiators are typically manufactured using injection molding, and the molded radiator needs to be easily demolded from the mold for subsequent processing and assembly.

[0003] In the prior art, such as the Chinese patent with authorization announcement number CN216139323U entitled "An Injection Mold for Car Radiator Processing with Edge Trimming Function", the above patent discloses an injection mold for car radiator processing with edge trimming function, including a mounting base plate, a material pushing and trimming mechanism, and a driving mechanism; the mounting base plate has three symmetrically distributed pads on its lower surface, a fixed mold base on the left side of the upper surface of the pads, a fixed mold core in the mounting opening in the middle of the fixed mold base through a connecting block, two symmetrically distributed T-shaped slide rails on the right side of the upper surface of the mounting base plate, a sliding opening at the bottom of the moving mold base slidingly connected to the T-shaped slide rails, a circular hole at the upper end of the moving mold base slidingly connected to a guide rod at the upper end of the right side of the fixed mold base, a moving mold head in the middle of the left side of the moving mold base, the moving mold head corresponding to the mold cavity in the middle of the fixed mold core, and a T-shaped mounting seat on the right side of the upper surface of the mounting base plate, the left side of the T-shaped mounting seat contacting the right end of the T-shaped slide rail.

[0004] Traditional automotive radiator demolding methods, such as those mentioned in the patent, primarily rely on the opening and closing of the mold, using a simple ejection mechanism to push the radiator out of the mold cavity. However, this method has several limitations. On the one hand, the radiator has a complex shape and delicate internal structure, making it easy for traditional ejection mechanisms to damage the radiator during demolding, affecting product quality. On the other hand, due to the adhesion between the radiator and the mold cavity, relying solely on the ejection mechanism makes it difficult to achieve fast and stable demolding, resulting in low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a demolding mechanism for automotive water tanks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car water tank demolding mechanism, including a template and a mold body installed on the template. The mold body is provided with a mold core for injection molding of workpieces, and an insert is slidably connected to one side of the mold core. The mold body and the insert are connected by a power component. When the mold body is in the opening stroke, the insert is driven by the power component to slide out of the mold body.

[0007] Furthermore, the insert is slidably connected to the mold body via a mounting block, and the power component is located between the mold body and the mounting block.

[0008] Furthermore, the power component includes an inclined guide post mounted on the mold body, and a driving block is provided on the mounting block, wherein the inclined guide post and the driving block are slidably connected.

[0009] Furthermore, the drive block has inclined grooves, and the inclined guide post is slidably connected to the drive block through the inclined grooves.

[0010] Furthermore, a limiting plate is installed on the mold body, and a limiting component is provided between the driving block and the limiting plate to improve the stability of the driving block when it slides.

[0011] Furthermore, the limiting component includes a limiting strip fixedly connected to the limiting plate, and the driving block has a limiting groove adapted to the limiting strip, with the limiting strip and the limiting groove being slidably connected.

[0012] Furthermore, a reset component is also provided between the mounting block and the mold body.

[0013] Furthermore, the reset component includes a slide rod fixedly connected to the mounting block, and the slide rod is slidably connected to the mold body. A cap is also fixedly connected to the slide rod, and a reset spring is provided between the cap and the mold body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the car water tank demolding mechanism, through the cooperation of the inclined guide post and the drive block, transforms the linear motion of the mold opening into the lateral sliding of the insert, realizing automated demolding and significantly improving production efficiency; moreover, the demolding power depends entirely on the mold opening action, requiring no additional energy, reducing costs and meeting the requirements of green manufacturing. At the same time, the mold can be adapted to car water tank molds of different shapes, and is especially suitable for demolding workpieces with complex internal structures, and has strong versatility.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-7 This utility model provides a technical solution: a car water tank demolding mechanism, including a template 1 and a mold body 2 installed on the template 1. The mold body 2 is provided with a mold core 3 for injection molding of workpieces, and an insert 4 is slidably connected to one side of the mold core 3. The mold body 2 and the insert 4 are connected by a power component. When the mold body 2 is in the opening stroke, the insert 4 is driven by the power component to slide out from the mold body 2.

[0020] Specifically, the automotive radiator demolding mechanism includes a template 1 and a mold body 2 mounted on the template 1. The template 1, serving as the support base for the entire demolding mechanism, is typically made of high-strength steel to ensure it can withstand high pressure without deformation during injection molding. The template 1 has positioning holes and mounting grooves for precisely fixing the mold body 2. The mold body 2 is bolted to the template 1 and has an internal mounting cavity for the mold core 3. The shape of the mold core 3 perfectly matches the injection cavity of the automotive radiator and is typically made of wear-resistant alloy steel to improve its service life. A sliding groove is provided on one side of the mold core 3, through which the insert 4 forms a sliding fit with the mold core 3. The insert 4 assists in molding the complex internal structure of the automotive radiator and slides away from the workpiece during demolding, reducing demolding resistance. The power component is fixed to the mold body 2. When the mold body 2 begins to open, the template 1 drives the mold body 2 to move, and the inclined guide post 8 moves accordingly. The inclined guide post 8, through its cooperation with the inclined groove 10 on the drive block 6, converts the linear motion of the mold body 2 into the lateral sliding of the insert 4, thereby pushing the insert 4 to slide out of the mold core 3. The entire transmission process requires no additional power source and relies entirely on the mold opening action, making it energy-saving and efficient.

[0021] In the embodiments provided by this utility model, the insert 4 is slidably connected to the mold body 2 through the mounting block 5, and the power component is set between the mold body 2 and the mounting block 5, which can improve the stability of the insert 4 during installation. The sliding distance between the mounting block 5 and the mold body 2 is controlled by the limiting plate 7 to prevent the demolding stroke from exceeding the limit.

[0022] In the embodiments provided by this utility model, the power component includes an inclined guide post 8 mounted on the mold body 2, and a driving block 6 is provided on the mounting block 5. The inclined guide post 8 and the driving block 6 are slidably connected. The inclined guide post 8 is a cylindrical rod with a surface hardened to improve wear resistance. Its inclination angle is designed according to the demolding force requirements, and the inclined guide post 8 is fixed to the mold body 2 by threads or interference fit to ensure that it will not loosen during high-speed mold opening.

[0023] In the embodiment provided by this utility model, the drive block 6 has an inclined groove 10, and the inclined guide post 8 is slidably connected to the drive block 6 through the inclined groove 10. When the mold is opened, the inclined guide post 8 slides along the inclined groove 10, pushing the drive block 6 to move laterally, thereby causing the insert 4 to detach from the workpiece.

[0024] In the embodiments provided by this utility model, a limiting plate 7 is installed on the mold body 2, and a limiting component 9 is provided between the driving block 6 and the limiting plate 7 to improve the stability of the driving block 6 when sliding. The limiting strip of the limiting component 9 is embedded in the limiting groove of the driving block 6, restricting the driving block 6 to slide only in the horizontal direction and preventing deviation or shaking.

[0025] In the embodiments provided by this utility model, the limiting member 9 includes a limiting strip fixedly connected to the limiting plate 7, and a limiting groove adapted to the limiting strip is provided on the driving block 6. The limiting strip and the limiting groove are slidably connected. The limiting strip is a rectangular steel strip, which is fixed to the limiting plate 7 by welding or bolts to meet the working requirements.

[0026] In the embodiments provided by this utility model, a reset component is also provided between the mounting block 5 and the mold body 2. The reset component includes a slide rod fixedly connected to the mounting block 5, and the slide rod is slidably connected to the mold body 2. A cap is also fixedly connected to the slide rod, and a reset spring is provided between the cap and the mold body 2 to improve the stability of the mounting block 5 during installation.

[0027] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources, and this application is equipped with a control system for controlling the operation of the entire equipment.
