Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a liquid silicone ejection mechanism. Background Technology

[0002] Liquid silicone ejection mechanism is an important component used in the production process of silicone products. Its function is to smoothly eject the silicone from the mold after it has solidified. Currently, the liquid silicone product industry has great limitations in product ejection, as silicone is a liquid with extremely high fluidity.

[0003] In the patent document with publication number CN221365677U, a liquid silicone ejection mechanism is disclosed. This device can control the sliding rod to slide inside the housing by moving the toggle block, thereby compressing the spring. By controlling the amount of compression of the spring, the thrust when the sliding rod ejects can be adjusted, thereby achieving the effect of using different thrusts to eject liquid silicone phone cases of different thicknesses.

[0004] However, this device is not conducive to demolding the silicone model after it has been produced. At the same time, it cannot fix the silicone model during the production process, which may cause the silicone model to shake during production, resulting in a model that cannot meet the design requirements.

[0005] Therefore, we propose a liquid silicone ejection mechanism to solve the above problems. Utility Model Content

[0006] The main purpose of this invention is to provide a liquid silicone ejection mechanism that can effectively solve the above problems.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A liquid silicone ejection mechanism includes a housing, an ejection device installed inside the housing, the ejection device including a pushing unit, a clamping unit, and a demolding unit, the pushing unit being installed inside the housing, the clamping unit being installed inside the housing, and the demolding unit being installed inside the housing.

[0009] The pushing unit includes a hydraulic rod one, which is fixedly connected to the top of the device housing. A compression spring one is connected to the outer surface of the output end of the hydraulic rod one. A connecting plate is fixedly connected to the bottom of the output end of the hydraulic rod one. A bracket is fixedly connected to the top of the connecting plate. A hydraulic rod two is fixedly connected to the bottom of the bracket.

[0010] Preferably, the clamping unit includes a movable rod, which is movably connected to the inner surface of the outer surface of the device housing. A compression spring is installed on the outer side of the movable rod. A blocking plate is fixedly connected to one end of the movable rod on the outer side of the device housing, and a pressing block is fixedly connected to the other end of the movable rod. A shaped block is fixedly connected to the bottom of the connecting plate. A sliding groove is fixedly connected to the inner side of the device housing, and a slide rail is fixedly connected to the bottom of the pressing block.

[0011] Preferably, the demolding unit includes a condensate tank, which is fixedly connected to the inside of the device housing. A transport pump is fixedly connected to the side of the condensate tank, and a transport pipe is fixedly connected to the side of the transport pump. A hollow placement block is fixedly connected to the other end of the transport pipe, and a return pipe is fixedly connected to the side of the hollow placement block.

[0012] Preferably, a model block is movably connected to the top of the hollow placement block.

[0013] Preferably, the irregularly shaped block is a trapezoidal block with an elliptical groove in the center, and the diameter of the groove is the same as the diameter of the moving rod.

[0014] Preferably, the condensate tank consists of a rapid cooling device, a condensate storage tank, etc., and the condensate storage tank is connected to the rapid cooling device through a liquid delivery pipe.

[0015] Beneficial effects:

[0016] 1. By installing the push unit, and further activating hydraulic rod one, the hydraulic rod one moves the connecting plate downward, which in turn moves the bracket and hydraulic rod two downward, thus enabling preliminary positioning of the ejection and making the ejection effect more precise.

[0017] 2. After the model block is placed by installing the clamping unit, the connecting plate begins to move downward. When the connecting plate moves downward, the irregular block moves downward, causing the irregular block to push the extrusion block inward to squeeze it, thereby fixing the model block. As a result, when the device ejects liquid silicone, the model block shakes, leading to a poor ejection effect. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-5 As shown, a liquid silicone ejection mechanism includes a device housing 1, an ejection device is installed inside the device housing 1, and the ejection device includes a pushing unit, a clamping unit, and a demolding unit. The pushing unit is installed inside the device housing 1, the clamping unit is installed inside the device housing 1, and the demolding unit is installed inside the device housing 1.

[0026] The pushing unit includes a hydraulic rod 201, which is fixedly connected to the top of the device housing 1. A compression spring 202 is connected to the outer surface of the output end of the hydraulic rod 201. A connecting plate 203 is fixedly connected to the bottom of the output end of the hydraulic rod 201. A bracket 204 is fixedly connected to the top of the connecting plate 203. A hydraulic rod 205 is fixedly connected to the bottom of the bracket 204. By installing the pushing unit and activating the hydraulic rod 201, the hydraulic rod 201 drives the connecting plate 203 to move downward, which in turn drives the bracket 204 and the hydraulic rod 205 to move downward. This allows for preliminary positioning of the ejection, resulting in a more precise ejection effect.

[0027] The clamping unit includes a moving rod 301, which is movably connected to the inner surface of the outer surface of the device housing 1. A compression spring 302 is installed on the outer side of the moving rod 301. A blocking plate 303 is fixedly connected to one end of the moving rod 301 on the outer side of the device housing 1, and a squeezing block 307 is fixedly connected to the other end of the moving rod 301. A shaped block 304 is fixedly connected to the bottom of the connecting plate 203. A slide groove 305 is fixedly connected to the inner side of the device housing 1. A slide rail 306 is fixedly connected to the bottom of the squeezing block 307. After the model block 5 is placed by installing the clamping unit, when the connecting plate 203 starts to move downward, the shaped block 304 moves downward, causing the shaped block 304 to push the squeezing block 307 inward to squeeze, thereby fixing the model block 5. As a result, when the device ejects liquid silicone, the model block 5 shakes, leading to a poor ejection effect.

[0028] The demolding unit includes a condensate tank 401, which is fixedly connected to the inside of the device housing 1. A transport pump 402 is fixedly connected to the side of the condensate tank 401, and a transport pipe 403 is fixedly connected to the side of the transport pump 402. The other end of the transport pipe 403 is fixedly connected to a hollow placement block 404, and a return pipe 405 is fixedly connected to the side of the hollow placement block 404. By installing the demolding unit, after the device ejects the liquid silicone, the transport pump 402 is activated to transport the condensate inside the condensate tank 401 to the inside of the hollow placement block 404, thereby cooling the hollow placement block 404 and further rapidly cooling the model inside the model block 5, making it easier to remove the model.

[0029] The top of the hollow placement block 404 is movably connected to the model block 5, so that by installing different types of model blocks 5, the type and appearance of the model production can be further changed, thereby improving the practicality of the device.

[0030] The irregular block 304 is a trapezoidal block with an elliptical groove in the center. The diameter of the groove is the same as the diameter of the moving rod 301. The irregular block 304 moves downward, so that the slope of the irregular block 304 contacts the extrusion block 307 and continues to move downward as the irregular block 304 moves downward. This causes the irregular block 304 to push the extrusion block 307 inward to squeeze, thereby completing the fixing effect of the model block 5.

[0031] The condensate tank 401 consists of a rapid cooling device and a condensate storage tank. The condensate storage tank is connected to the rapid cooling device through a liquid delivery pipe. When the model needs to be cooled, the condensate is rapidly cooled by the rapid cooling device through the condensate storage tank. It is then transported to the interior of the hollow placement block 404 by the transport pump 402, thereby cooling the model and facilitating demolding.

[0032] It should be noted that the specific installation methods, circuit connection methods, and control methods of the hydraulic rod 201, hydraulic rod 205, and transport pump 402 used in this utility model are all conventional designs, and will not be described in detail here.

[0033] The working principle of this utility model is as follows: After placing the model block 5 on top of the hollow placement block 404, the hydraulic rod 201 is activated, causing the connecting plate 203 to move downwards, which in turn moves the bracket 204 and the hydraulic rod 205 downwards, thus providing initial positioning for the ejection. As the connecting plate 203 moves downwards, the irregular block 304 moves downwards, pushing the extrusion block 307 inwards to press and fix the model block 5. After the model is ejected by activating the hydraulic rod 205, the condensate in the condensate tank 401 is transported to the interior of the hollow placement block 404 by activating the transport pump 402, thereby cooling the hollow placement block 404 and rapidly cooling the model inside the model block 5, making it easier to remove the model.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
