Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber injection molding device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. There are many methods to produce rubber. Among them, injection molding is widely used in the rubber processing field due to its advantages such as fast production speed, high efficiency and automated operation.

[0003] However, in the prior art, after the rubber is molded by the injection mold, although the molded rubber can be taken out from the injection mold by a demolding mechanism, the injection mold will only fall into the inside of the workbench by its own gravity. When the staff wants to take out the molded mold, they need to put their hands into the inside of the workbench. When taking it out, it is very likely to touch the working injection mold and cause damage to the hands. Therefore, it is necessary to propose a new type of rubber injection molding device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that after the rubber is molded by the injection mold, although the molded rubber can be taken out from the injection mold by the demoulding mechanism, the injection mold will only fall into the inside of the workbench by its own gravity. When the staff wants to take out the molding mold, they need to put their hands into the inside of the workbench, and it is very likely to touch the working injection mold when taking it out, causing damage to the hands. By setting a material transport mechanism, the molding mold is transported out of the workbench to solve the problem raised in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rubber injection molding device, comprising: a workbench, four supporting columns are fixedly installed on the top of the workbench, a top plate is fixedly installed on the top of the four supporting columns, an upper mold is fixedly installed on the bottom of the top plate, two hydraulic rods are fixedly inserted on the top of the top plate, a lower mold is fixedly installed on the output ends of the two hydraulic rods, four demolding holes are opened on the inner wall of the lower mold, demolding columns are movably inserted on the inner walls of the four demolding holes, and fixing rings are fixedly installed on the outer walls of the four demolding columns, an electric telescopic rod is fixedly inserted on one side of the outer wall of the workbench, a push plate is fixedly installed on the output end of the electric telescopic rod, a sliding groove is opened on the top of the workbench, a multi-section telescopic rod is fixedly inserted on one side of the outer wall of the workbench, and a transport box is fixedly installed on the output end of the multi-section telescopic rod.

[0006] Preferably, limit blocks are fixedly installed on both sides of the outer wall of the transport box, and the outer walls of the two limit blocks are movably inserted into the inner wall of the sliding groove, so that the transport box can be limited when the multi-section telescopic rod adjusts the position of the transport box.

[0007] Preferably, a pressure sensor is fixedly installed on the bottom of the inner wall of the transport box, and the pressure sensor is electrically connected to the multi-section telescopic rod. A pressure plate is fixedly installed on the top of the pressure sensor, so that when a finished product falls into the transport box, it will be detected by the pressure sensor, thereby triggering the multi-section telescopic rod to drive the transport box to move.

[0008] Preferably, an indicator light is fixedly mounted on one side of the outer wall of the workbench, and the indicator light is electrically connected to the multi-section telescopic rod, so that after the multi-section telescopic rod moves to the shortest distance, the indicator light is triggered to sound an alarm, thereby reminding the staff to take out the finished product.

[0009] Preferably, springs are provided on the tops of the four fixed rings, two limit columns are fixedly installed between the top of the workbench and the bottom of the top plate, and the outer walls of the two limit columns are movably inserted into the inner wall of the lower mold, so as to limit the hydraulic rod when the hydraulic rod drives the lower mold to move.

[0010] Preferably, four limit frames are fixedly installed on the top of the workbench, and the inner walls of the four limit frames are respectively engaged with the outer walls of the four demoulding columns, so as to facilitate the limiting of the demoulding columns by the limit frames to prevent the demoulding columns and the workbench from slipping, resulting in instability of the demoulding columns.

[0011] Preferably, the bottom of the inner wall of the push plate is a slope structure, and one side of the inner wall of the transport box is a slope structure, so that the finished product can slide smoothly by utilizing the slope structure on the push plate, and the transport box can also be smoothly connected to the finished product through the slope structure of the transport box.

[0013] 1. In the utility model, by arranging a push plate and a transport box, when the workbench allows the rubber to be injection molded, it will be pushed out of the lower mold by the demoulding column and be in a floating state, and then the electric telescopic rod is started to drive the push plate to push out the rubber product, and after being briefly supported by the bottom of the push plate, it is pushed to the top of the transport box, allowing the rubber product to fall into the transport box by its own gravity. At this time, the multi-section telescopic rod is started to pull the transport box away from the upper mold and the lower mold, so that the staff can directly take out the finished product, thereby avoiding the problem of being injured by touching the working upper mold and the lower mold when taking out the rubber product, improving the safety of the device and protecting the life safety of the staff.

[0014] 2. In the utility model, a spring is provided, and whenever the lower mold moves downward and the demoulding column demoulds the finished product, the spring will be used for shock absorption to prevent the vibration generated during demoulding, which will shake the finished product off from the top of the demoulding column, causing the push plate to be unable to push the finished product normally. Then, a slope structure is provided on the top of the push plate and the transport box, so that when the finished product is pushed to the top of the transport box, it will fall into the transport box through the slope structure of the push plate, and slide smoothly to the inside of the transport box through the slope structure of the transport box, thereby ensuring that the finished product can be transported smoothly and achieving the stability of the device.

[0023] The effect achieved by the entire embodiment 1 is that, by setting the push plate 11 and the transport box 14, when the workbench 1 is used for rubber injection molding, it will be pushed out of the lower mold 6 by the demoulding column 8 and will be in a floating state, and then the electric telescopic rod 10 will be started to drive the push plate 11 to push out the rubber product, and after being briefly supported by the bottom of the push plate 11, it will be pushed to the top of the transport box 14, allowing the rubber product to fall into the transport box 14 by its own gravity. At this time, the multi-section telescopic rod 13 will be started to pull the transport box 14 away from the upper mold 5 and the lower mold 6, so that the staff can directly take out the finished product, thereby avoiding the problem of being injured by touching the working upper mold 5 and the lower mold 6 when taking out the rubber product, thereby improving the safety of the device and protecting the lives of the staff.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, limit blocks 15 are fixedly installed on both sides of the outer wall of the transport box 14, and the outer walls of the two limit blocks 15 are movably inserted in the inner wall of the sliding groove 12, a pressure sensor 16 is fixedly installed at the bottom of the inner wall of the transport box 14, and the pressure sensor 16 is electrically connected to the multi-section telescopic rod 13, a pressure plate 17 is fixedly installed on the top of the pressure sensor 16, an indicator light 18 is fixedly installed on one side of the outer wall of the workbench 1, and the indicator light 18 is electrically connected to the multi-section telescopic rod 13, springs 19 are provided on the tops of the four fixing rings 9, two limit columns 21 are fixedly installed between the top of the workbench 1 and the bottom of the top plate 3, and the outer walls of the two limit columns 21 are movably inserted in the inner wall of the lower mold 6, four limit frames 20 are fixedly installed on the top of the workbench 1, and the inner walls of the four limit frames 20 are respectively engaged with the outer walls of the four demolding columns 8, the bottom of the inner wall of the push plate 11 is a slope structure, and one side of the inner wall of the transport box 14 is a slope structure.

[0025] The effect achieved by the entire embodiment 2 is that, by setting the spring 19, whenever the lower mold 6 moves downward and the demolding column 8 demolds the finished product, the spring 19 will be used for shock absorption to prevent the vibration generated during demolding, which will shake the finished product off the top of the demolding column 8, causing the push plate 11 to be unable to push the finished product normally, and then the top of the push plate 11 and the transport box 14 are provided with a slope structure, so that when the finished product is pushed to the top of the transport box 14, it will fall into the transport box 14 through the slope structure of the push plate 11, and slide smoothly into the interior of the transport box 14 through the slope structure of the transport box 14, thereby ensuring that the finished product can be transported smoothly and achieving the stability of the device.

[0026] The working principle of the whole device is as follows: start the hydraulic rod 4, and drive the lower mold 6 to move upward under the action of the limiting column 21 until it moves to the space between the upper mold 5 and the lower mold 6 to fit and seal, and then use the feed to inject the rubber raw material through the feeding port of the upper mold 5 for injection molding. After the injection molding is completed, start the hydraulic rod 4 again to move the lower mold 6 downward. After moving to a certain distance, the demoulding column 8 will be inserted into the inside of the limiting frame 20 to push the finished product inside the lower mold 6 upward. During the ejection process, it will also be damped by the spring 19, so that the finished product stays on the top of the four demoulding columns 8. At this time, start the electric telescopic rod 10 to drive the push plate 11 to push the finished product, and then The finished product will move toward the top of the transport box 14 under the support of the bottom of the push plate 11 and the thrust of the push plate 11, until it moves to the top of the transport box 14, then stop pushing, and then the finished product will slide downward through the slope structure of the push plate 11, and then fall into the inside of the transport box 14 through the slope structure of the transport box 14. When the finished product falls into the transport box 14, it will generate an impact force on the pressure plate 17, which will be detected by the pressure sensor 16, and then the pressure sensor 16 will trigger the multi-section telescopic rod 13 to move the transport box 14 away from the upper mold 5 under the action of the limit block 15. After moving to the farthest point, the indicator light 18 is triggered to remind the staff that they can take out the finished product.
