Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a new type of production mold for a medical silicone pad with a cannon head. Background Technology

[0002] Medical silicone pads typically refer to silicone material products used in medical settings that provide anti-slip, protective, cushioning, and pressure-reducing functions. These pads are usually made of medical-grade silicone, possessing good biocompatibility, high-temperature resistance, pressure resistance, and easy cleaning. Injection molding is an essential process in silicone production. Injection molds are industrial tools used to produce plastic products. The raw material is usually hot-melt rubber or plastic, which is added to the mold and injected. Molds are the main molding equipment used to create various shapes of plastic products.

[0003] Typically, an injection mold consists of a mold body and a mold cavity. The plastic raw material is completely melted by the screw of the injection molding machine through stirring and heating. Then, the molten plastic is injected into the mold cavity under certain pressure and speed. Finally, after cooling and solidification, a product with the same shape as the mold cavity is obtained. The injection molding process can be roughly divided into six stages: mold closing, injection, pressure holding, cooling, mold opening, and product removal. By repeating these processes, products can be produced in batches and periodically.

[0004] However, if air cannot be expelled in time when molten plastic fills the mold cavity, it will be trapped inside the mold cavity, forming bubbles or shrinkage cavities, which will affect the strength and appearance of the medical silicone pad.

[0005] Based on this, this utility model designs a new type of production mold for medical silicone pads with cannon heads to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a body comprising a cavity surrounded by multiple side walls. A through hole is provided in the cavity, with both ends of the through hole connecting the cavity to the outside of the body. A connecting block is slidably disposed within the through hole, with one end of the connecting block connected to a driving component. The connecting block is adapted to the shape of the through hole. A clearance groove is provided on one side of the through hole, and an air vent is fixedly disposed in the clearance groove. An air pump is disposed on the body, and the air pump is fixedly connected to the air vent. When the connecting block slides outwards from the body, a ventilation channel is formed between the connecting block and the clearance groove. The air pump draws air from the cavity through the ventilation channel, allowing the gas in the cavity to be discharged, thereby improving the product quality of the mold.

[0007] By adopting the above technical solution, the air channel is automatically formed by the sliding of the connecting block, and the air pump directly evacuates the cavity, allowing the silicone pad to quickly detach from the cavity. This reduces the deformation or damage caused by traditional ejection mechanisms. The air channel is integrated between the through hole and the connecting block, so that after the air pump finishes evacuating, the connecting block slides again until the connecting block completely blocks the air channel. There is no need to design a complicated exhaust system, saving mold space. It has a significant demolding effect on thin-walled or complex medical silicone pads.

[0008] Preferably, the drive assembly includes a motor and a gear, the gear being coaxially connected to the motor shaft, and the connecting block having a plurality of tooth grooves, the gear meshing with the tooth grooves.

[0009] By adopting the above technical solution, the gear meshing transmission can precisely control the sliding distance of the connecting block, ensuring that the opening and closing of the ventilation channel and the air extraction are synchronized, thereby improving the sliding efficiency and accuracy of the connecting block.

[0010] Preferably, a pressing block is provided on the side of the through hole near the cavity, and the pressing block presses against the side of the connecting block.

[0011] By adopting the above technical solution, the pressure block assists in sealing the through hole when the connecting block is reset, preventing gas leakage and ensuring vacuum.

[0012] Preferably, the air pump is equipped with an air pressure sensor at its suction end.

[0013] By adopting the above technical solution, the air pressure in the cavity is monitored to avoid excessive air extraction causing the silicone pad to sink in or insufficient air extraction causing demolding failure, thereby improving the yield rate.

[0014] Preferably, a controller is provided between the pressure sensor and the drive assembly.

[0015] By adopting the above technical solution, closed-loop regulation of the air extraction process can be achieved, reducing manual intervention, improving production efficiency, avoiding ineffective operation of the air pump, and reducing energy consumption.

[0016] Preferably, the air intake tube is a high-temperature resistant silicone tube.

[0017] By adopting the above technical solution, the air vent can adapt to the high temperature environment of the injection mold and will not deform or crack during long-term use.

[0018] In summary, this application has the following beneficial technical effects: It includes a body comprising a cavity surrounded by multiple sidewalls. A through hole is provided in the cavity, with both ends of the through hole connecting the cavity to the outside of the body. A connecting block is slidably disposed within the through hole, with one end of the connecting block connected to a driving component. The connecting block is adapted to the shape of the through hole. A clearance groove is provided on one side of the through hole, and an air vent is fixedly disposed in the clearance groove. An air pump is disposed on the body, and the air pump is fixedly connected to the air vent. When the connecting block slides outwards from the body, a ventilation channel is formed between the connecting block and the clearance groove. The air pump draws air from the cavity through the ventilation channel, allowing the gas in the cavity to be discharged, thereby improving the product quality of the mold.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] A novel production mold for a medical silicone pad with a cannon tip includes a body 1. The body 1 includes a cavity 12 surrounded by multiple side walls. A through hole 10 is provided on the cavity 12. The two ends of the through hole 10 are respectively connected to the outside of the cavity 12 and the body 1. A connecting block 5 is slidably arranged in the through hole 10. One end of the connecting block 5 is connected to a driving component. The shape of the connecting block 5 is adapted to the through hole 10. A relief groove 11 is provided below the through hole 10. An air duct 8 is fixedly arranged in the relief groove 11. The side wall of the air duct 8 fits against the relief groove 11. An air pump 4 is provided on the body 1. The air pump 4 is fixedly connected to the air duct 8.

[0025] In use, pull the connecting block 5 to slide it away from the cavity 12. After the connecting block 5 slides, the groove 11, the through hole 10 and the cavity 12 are connected. At this time, turn on the air pump 4. The air pump 4 starts to draw air into the cavity 12 through the air pipe 8, so that the gas in the cavity 12 is gradually drawn out. When the gas in the cavity 12 is reduced to a certain extent, push the connecting block 5 into the through hole 10 so that the through hole 10 can be blocked, so that the channel between the groove 11 and the cavity 12 disappears and the air pressure in the cavity 12 is stable. At this time, the product is manufactured, which makes it easier to demold the product and improves the demolding efficiency of the device.

[0026] The drive assembly includes a motor 3 and a gear 6. The gear 6 is coaxially connected to the rotating shaft of the motor 3. Several toothed grooves 7 are provided on the connecting block 5. The gear 6 meshes with the toothed grooves 7. The air pump 4 has a pressure sensor 13 at its suction end. The pressure sensor 13 is connected to the drive assembly. A controller 2 is provided between the pressure sensor 13 and the drive assembly. When the motor 3 is turned on, the rotating shaft on the motor 3 drives the gear 6 to rotate. The gear 6 meshes with the toothed grooves 7 continuously, causing the connecting block 5 to slide along the through hole 10. The position of the slider in the through hole 10 is controlled by the motor 3, making the movement of the slider more precise and efficient. After the slider moves a certain distance, the controller 2 controls the air pump 4 to start evacuating. When the vacuum degree in the cavity 12 reaches the set threshold, the controller 2 controls the air pump 4 to stop running, and the motor 3 rotates in the opposite direction until the connecting block 5 completely blocks the through hole 10.

[0027] A pressure block 9 is provided on the side of the through hole 10 near the cavity 12. The pressure block 9 assists in sealing the through hole 10 when the connecting block 5 is reset. The pressure block 9 presses against the side of the connecting block 5 to prevent gas leakage and ensure vacuum. The air duct 8 is a high-temperature resistant silicone tube. The temperature inside the cavity 12 is high when the mold is in use. The high-temperature resistant material can adapt to the high-temperature environment of the injection mold and will not deform or crack after long-term use.

[0028] The implementation principle of this embodiment is as follows: When in use, the motor 3 is turned on, causing the shaft on the motor 3 to drive the gear 6 to rotate. The gear 6 and the tooth groove 7 continuously mesh, causing the connecting block 5 to slide away from the cavity 12. After the connecting block 5 slides, the slot 11, the through hole 10 and the cavity 12 are interconnected. After the slider moves to a certain distance, the controller 2 controls the air pump 4 to start pumping air, so that the gas in the cavity 12 is gradually extracted. When the gas in the cavity 12 is reduced to a certain level, when the vacuum degree in the cavity 12 reaches the set threshold, the controller 2 controls the air pump 4 to stop running, and the motor 3 rotates in the opposite direction until the connecting block 5 completely blocks the through hole 10, the channel between the slot 11 and the lightweight body disappears, and the air pressure in the cavity 12 stabilizes.
