Description

Technical Field

[0001] This application relates to the field of injection molds, and more specifically, to a rapid cooling device for automotive injection molds. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding of complex products, such as various automotive parts.

[0003] Currently, injection molds are used to manufacture many one-piece molded parts. During the use of injection molds, it is inconvenient to remove the molded products. Traditionally, many injection molds use springs to push ejector pins to eject the products. However, springs are prone to fatigue after long-term use. In addition, the shape of the workpiece limits the ejection of the workpiece, which can lead to the workpiece not being able to be ejected. Furthermore, the cooling chambers of most injection molds have insufficient cooling contact surfaces, resulting in low cooling efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing methods, this application provides a rapid cooling device for automotive injection molds. This device solves the problems of traditional methods that use springs to push ejector rods, which can lead to spring fatigue after long-term use, workpiece shape limitations, and situations where the workpiece cannot be ejected. Furthermore, the cooling chambers of most injection molds have insufficient cooling contact surfaces, resulting in low cooling efficiency.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A rapid cooling device for automotive injection molds includes a cooling component and a demolding component.

[0007] The cooling assembly includes a support platform, a hydraulic rod, a lower mold, a flat tube, and an upper mold. The hydraulic rod is disposed on the top of the support platform, the lower mold is fixedly connected to the support platform, the flat tube is fixedly inserted through the lower mold, and the upper mold is installed on the top of the hydraulic rod.

[0008] The demolding assembly includes a rotating shaft, a large gear, a small gear, a first rack plate, a second rack plate, and an ejector. The rotating shaft is rotatably mounted on the bottom of the support platform. The large gear and the small gear are both fixedly sleeved on the rotating shaft. The first rack plate is connected to the side of the hydraulic rod and meshes with the large gear. The ejector slides through the lower mold and the support platform. The second rack plate is fixedly connected to the ejector and meshes with the small gear.

[0009] In one specific implementation, a mounting bracket is fixedly connected to the top of the hydraulic rod, and the upper mold is mounted on the bottom of the mounting bracket.

[0010] In the above implementation process, a mounting bracket is set up to install the mold with bolts, which allows for assembly and disassembly.

[0011] In one specific implementation, the first rack plate is fixedly connected to the mounting frame, and the first rack plate slides through the support platform.

[0012] In one specific implementation, the support platform has a through hole, through which the first rack plate slides.

[0013] In the above implementation process, through holes are opened to guide the first rack plate to slide stably.

[0014] In one specific implementation, the top material component includes a movable plate and a top rod. The movable plate is slidably disposed at the bottom of the support platform, the top rod is installed on the movable plate, and the top rod slidably passes through the lower mold and the support platform. The second rack plate is fixedly connected to the movable plate.

[0015] In the above implementation process, by setting a movable plate and a push rod, the second rack plate drives the movable plate to move, and the movable plate drives the push rod to move.

[0016] In one specific implementation, a guide rod is fixedly connected to the bottom of the support platform, and the movable plate is slidably sleeved on the guide rod.

[0017] In the above implementation process, a guide rod is set to guide the moving plate to slide in a stable linear motion.

[0018] In one specific implementation, the support platform has an opening through which the top rod passes.

[0019] In the above process, by creating a large opening, the ejector pin can pass through the opening and then through the lower mold.

[0020] In one specific implementation, the movable plate has multiple threaded holes, and the push rod is threadedly connected to the threaded holes.

[0021] In the above implementation process, by opening multiple threaded holes, the number and position of the ejector pins can be adjusted to allow for adjustment of the ejector pins when used with different lower molds.

[0022] The advantages of this embodiment are: by setting up a support platform, hydraulic rod, lower mold, flat tube and upper mold, the flat tube can increase the contact area and improve the cooling efficiency. By setting up a rotating shaft, large gear, small gear, first rack plate, second rack plate and ejector, the ejector can be moved synchronously during demolding after molding. The ejector pushes the product out of the lower mold, ensuring ejection capacity and improving practicality. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0029] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0030] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0031] Please see Figures 1-4 This application provides a rapid cooling device for automotive injection molds, including a cooling component 100 and a demolding component 200.

[0032] Please see Figure 1 , 23. The cooling assembly 100 includes a support platform 110, a hydraulic rod 120, a lower mold 130, a flat tube 140, and an upper mold 150. The hydraulic rod 120 is disposed on the top of the support platform 110. The lower mold 130 is fixedly connected to the support platform 110. The flat tube 140 is fixedly inserted through the lower mold 130. The upper mold 150 is installed on the top of the hydraulic rod 120. The flat tube 140 is connected to an external cooling water circulation system, which is conventional prior art.

[0033] The hydraulic rod 120 has a mounting bracket 121 fixedly connected to its top end. The upper mold 150 is installed at the bottom of the mounting bracket 121. The mounting bracket 121 is used to install the upper mold 150 with bolts, and it can be disassembled and assembled.

[0034] Please see Figure 1 , 2 4. The demolding assembly 200 includes a rotating shaft 210, a large gear 220, a small gear 230, a first rack plate 240, a second rack plate 250, and an ejector 260. The rotating shaft 210 is rotatably mounted on the bottom of the support platform 110. The large gear 220 and the small gear 230 are both fixedly sleeved on the rotating shaft 210. The first rack plate 240 is connected to the side of the hydraulic rod 120 and meshes with the large gear 220. The ejector 260 slides through the lower mold 130 and the support platform 110. The second rack plate 250 is fixedly connected to the ejector 260 and meshes with the small gear 230.

[0035] The first rack plate 240 is fixedly connected to the mounting bracket 121. The first rack plate 240 slides through the support platform 110. The support platform 110 has a through hole 111. The first rack plate 240 slides through the through hole 111. The through hole 111 is used to guide the first rack plate 240 to slide stably.

[0036] In this embodiment, the top material component 260 includes a movable plate 261 and a top rod 262. The movable plate 261 is slidably disposed at the bottom of the support platform 110, and the top rod 262 is installed on the movable plate 261. The top rod 262 slides through the lower mold 130 and the support platform 110. The second rack plate 250 is fixedly connected to the movable plate 261. By setting the movable plate 261 and the top rod 262, the second rack plate 250 drives the movable plate 261 to move, and the movable plate 261 drives the top rod 262 to move.

[0037] Specifically, a guide rod 112 is fixedly connected to the bottom of the support platform 110, and the moving plate 261 is slidably sleeved on the guide rod 112. The guide rod 112 is used to guide the moving plate 261 to slide stably in a straight line.

[0038] It should be noted that the support platform 110 has an opening 113, through which the ejector rod 262 passes. By opening a larger opening 113, the ejector rod 262 can pass through the opening 113 and then through the lower mold 130.

[0039] In one specific implementation, the movable plate 261 has multiple threaded holes 2611, and the ejector rod 262 is threaded to the threaded holes 2611. By opening multiple threaded holes 2611, the number and position of the ejector rod 262 can be adjusted to achieve adjustment when the ejector rod 262 is used for different lower molds 130.

[0040] The working principle of this rapid cooling device for automotive injection molds is as follows: During operation, the hydraulic rod 120 retracts, causing the mounting bracket 121 to move. The mounting bracket 121 then moves the upper mold 150 downwards to fit against the lower mold 130. Simultaneously, the mounting bracket 121 moves the first rack plate 240 downwards, engaging with the large gear 220, which in turn rotates the rotating shaft 210. The rotating shaft 210 then rotates the small gear 230, which in turn moves the second rack plate 250. The second rack plate 250 then moves the moving plate 261, which in turn moves the ejector rod 262. The top moves to the bottom of the lower mold 130, and then the raw material is injected through the injection hole at the top of the upper mold 150. Cooling water is then cooled through the flat tube 140. The flat tube 140 increases the contact area and improves the cooling efficiency. After molding, the hydraulic rod 120 extends, which in turn drives the ejector rod 262 to move upward. The ejector rod 262 ejects the molded product out of the lower mold 130, thus ensuring smooth product ejection. Furthermore, by opening multiple threaded holes 2611, the number and position of the ejector rod 262 can be adjusted to allow for adjustment when using different lower molds 130.

[0041] It should be noted that the specific model and specifications of the hydraulic rod 120 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0042] The power supply and principle of the hydraulic rod 120 are clear to those skilled in the art and will not be described in detail here.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
