Description

Technical Field

[0001] The utility model relates to the technical field of laryngeal mask production, in particular to a silicone laryngeal mask injection mould. Background Art

[0002] Laryngeal mask is an effective means of establishing a safe airway during general anesthesia surgery. Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] As disclosed in the authorization announcement number CN211221829U, a silicone laryngeal mask injection mold is disclosed, including an upper mold device and a lower mold device. Through the cooperation between the ejector structure and the first groove, the positioning accuracy of the device is increased, and the work efficiency is improved. Through the cooperation between the buckle and the pressure block, the upper mold body and the lower mold body are better fixed, which not only improves the stability of the device in use, but also prevents the overflow of silicone liquid during the injection molding process and the appearance of burrs on the processed silicone, thereby improving the quality of the product. The heat dissipation structure can dissipate the heat generated during the injection molding process, avoiding excessive mold temperature from affecting the molding and solidification of silicone in the molding area, which not only ensures the molding effect, but also further improves the work efficiency. The setting of the buffer structure can prevent the impact force generated by the upper mold body and the lower mold body during long-term use from damaging the device itself, thereby increasing the buffering effect and extending the service life of the device.

[0004] However, currently available injection molds can only process a single product and have a relatively low range of use. In addition, due to the high cost of the mold, a single mold increases the range of use while also reducing costs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0023] A silicone laryngeal mask injection mold comprises an injection mechanism 101, a molding mechanism 102 and a lifting mechanism 103, wherein the molding mechanism 102 is located at the bottom end of the injection mechanism 101, the lifting mechanism 103 is located at the bottom end of the injection mechanism 101, and the injection mechanism 101 comprises an upper module 104, wherein the top of the upper module 104 is provided with mounting screw grooves 105 around, the top middle of the upper module 104 is provided with an injection groove 106, and the bottom end of the upper module 104 is fixedly installed with a positioning rod 201.

[0024] Through the above scheme, the upper module can be installed and connected to the injection molding machine by installing the screw groove, the raw materials in the injection molding machine can be injected through the injection groove, and the positioning rod can maintain a stable position when pressing down for injection molding to prevent dislocation from causing overall damage to the mold or unqualified products.

[0025] In this embodiment, preferably, the forming mechanism 102 includes a lower module 202, a first screw 306 and a second screw 401. Positioning grooves 203 are opened around the top of the lower module 202. A positioning sleeve 204 is movably installed in the positioning groove 203. A spring 205 is fixedly installed in the positioning sleeve 204. A positioning screw 206 is fixedly installed at the bottom of the positioning sleeve 204.

[0026] Through the above scheme, the positioning sleeve can be installed through the positioning groove, so that the position can be kept stable and will not be misplaced during downward pressure injection molding. The upper module and the lower module can be quickly separated through spring rebound, and can be installed with the support block through the positioning screw.

[0027] In this embodiment, preferably, a pad 301 is movably installed at the bottom of the lower module 202, first lifting holes 302 are opened on the left and right sides of the top of the lower module 202, and a combination module 303 is movably installed in the middle of the top of the lower module 202.

[0028] Through the above solution, the pad can prevent the support block from being damaged when pressing down, and at the same time increase the friction between the lower module and the support block to prevent gaps from being generated at the connection, causing shaking during production and making the product unqualified.

[0029] In this embodiment, preferably, a model groove 304 is opened at the top of the combination module 303, a second lifting hole 305 is opened in the model groove 304, the first screw 306 passes through the front end of the lower module 202 and is movably installed in the combination module 303, and the second screw 401 passes through the right end of the lower module 202 and is movably installed in the combination module 303.

[0030] Through the above solution, the combined module can be fixed in the lower module by the first screw and the second screw, and the combined module can be replaced, so that the mold can replace different modules according to different products, thereby increasing the scope of application.

[0031] In this embodiment, preferably, the lifting mechanism 103 includes a support block 402, a positioning screw groove 403 is opened around the top of the support block 402, a positioning screw 206 is movably installed in the positioning screw groove 403, a lifting groove 404 is opened at the top of the support block 402, and a lifter 405 is fixedly installed at the bottom of the lifting groove 404.

[0032] Through the above solution, the positioning screw can be installed through the positioning screw groove, so that the lower module and the support block are installed and fixed.

[0033] In this embodiment, preferably, a lifting block 406 is movably installed on the top of the lifter 405, and first lifting rods 501 are movably installed on the left and right sides of the top of the lifting block 406. A second lifting rod 502 is fixedly installed in the middle of the top of the lifting block 406, and a model 503 is movably installed on the top of the second lifting rod 502.

[0034] According to the above scheme, the lifting block is driven to move up and down by the lifter, which can drive the first lifting rod and the second lifting rod to move up and down, so that the model is lifted and the product is quickly separated from the model slot.

[0035] When the silicone laryngeal mask injection mold of the present embodiment is in use, the user installs the combined module 303 and the lower module 202 through the first screw 306 and the second screw 401, then penetrates the first lifting rod 501 into the first lifting hole 302, penetrates the second lifting rod 502 into the second lifting hole 305, and installs the model 503 to the top of the second lifting rod 502, and installs the gasket to the connection between the lower module 202 and the support block 402. Finally, the positioning screw 206 is installed in the positioning screw groove 403 to complete the installation. During injection molding, the upper module 104 is pressed down by the injection molding machine so that the positioning rod 201 penetrates into the positioning sleeve 204 and presses the spring 205 downward. After pressing, the injection molding machine injects the molten raw material into the combined module 303 through the injection port. At this time, the gap generated by the model 503 and the model groove 304 is filled with the raw material. After the molding is completed, when the injection molding machine drives the upper module 104 to rise, the positioning rod 201 is moved out of the positioning sleeve 204, so that the spring 205 rebounds to quickly separate the upper module 104 from the lower module 202, preventing the upper module 104 from sticking to the product after injection molding, thereby preventing the displacement of the lower module 202 from driving the product to tear the product. At the same time, the lifter 405 drives the lifting block 406 to rise, so that the second lifting rod 502 drives the model 503 to rise through the second lifting hole 305. The rise separates the product from the model groove 304, so that it is convenient for the worker to quickly peel the product from the model 503. The first lifting rod 501 rises in the first lifting hole 302, which can keep the lifter 405 stable when driving the lifting block 406 to rise, and prevent the second lifting rod 502 from being dislocated when rising and damaging the mold and equipment.
