Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a rapid prototyping mold for gel eye patches. Background Technology

[0002] Medical hydrogel eye patches are widely used in modern medicine and beauty care due to their excellent moisturizing and soothing properties. They provide a comfortable, moist environment for the eyes, effectively relieving symptoms such as dryness and fatigue caused by prolonged use of electronic devices or dry environments. Furthermore, hydrogel eye patches play an important role in the medical field, especially in patients under general anesthesia or in a deep coma. By providing a relatively closed and moist environment outside the eye, they can effectively prevent exposure keratitis and protect corneal health.

[0003] Patent CN115946269A discloses a mold and method for preparing gel eye patches. The mold includes a main mold and a capping mold. The main mold has an eye patch forming groove and several capping insertion grooves. The groove shape of the eye patch forming groove is the same as the outline of the pre-prepared gel eye patch. The eye patch forming groove is located in the middle of the main mold, and the capping insertion grooves are located on the outer periphery of the eye patch forming groove. The capping mold has an insertion boss that cooperates with the capping insertion groove, so that the capping mold can be inserted and fixed to the main mold, covering the gel eye patch forming groove under the capping mold. The preparation method uses the above mold, and finally, the gel eye patch and the mold are packaged together in a packaging bag and sealed. This invention reduces the probability of reduced adhesiveness of medical adhesive tape due to gel hydration; it also greatly reduces the probability of damage to gel eye patches during production and transportation; and it improves the production efficiency and quality of gel eye patches.

[0004] Although the aforementioned existing technology reduces the probability of damage during production and transportation by sealing the mold together with the gel eye patch, it still has shortcomings in terms of production efficiency. Specifically, after the gel liquid is poured into the molding groove of the main mold, it still needs to be cured and shaped by additional heating and cooling equipment, which increases the complexity and time cost of production. In addition, the efficiency and continuity of the production process are affected due to the lack of a rapid prototyping processing structure. In view of this, we propose a rapid prototyping mold for gel eye patches. Utility Model Content

[0005] The purpose of this invention is to provide a rapid prototyping mold for gel eye patches to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid prototyping mold for gel eye patches includes a lower mold, which includes a U-shaped support. The top of the U-shaped support has a heating chamber, and an electric heating plate is provided inside the heating chamber to provide a suitable temperature for rapid curing of the gel material and improve gel curing efficiency. A template is detachably connected to the top of the U-shaped support by bolts. The top of the template has multiple rectangularly arranged molding cavities for holding the gel liquid and forming the basic shape of the eye patch.

[0008] The lower mold has an upper mold at its top, and an air cavity is formed inside the upper mold. The bottom of the upper mold has clearance grooves corresponding to the positions of multiple molding cavities. The clearance grooves are located directly above the multiple molding cavities to prevent the upper mold from contacting the gel liquid and ensure effective molding of the gel liquid. The top of the inner wall of the clearance groove has an air outlet that communicates with the air cavity. The top of the upper mold has an air-cooling component for inputting airflow into the air cavity. The airflow generated by the air-cooling component enters the air cavity and is then output from the multiple air outlets, thereby blowing air to dissipate heat from the gel eye patch that has been heated and solidified in the molding cavity, thereby improving cooling efficiency and enabling the gel eye patch to be molded quickly.

[0009] Preferably, a discharge component is provided between the left and right sides of the inner wall of the U-shaped bracket, which works in conjunction with the lower mold to output the finished gel eye patch, ensuring smooth production. The discharge component includes a strip-shaped horizontal plate, with its left and right ends fixedly connected to the left and right sides of the inner wall of the U-shaped bracket, respectively. An electric telescopic rod is provided in the middle of the bottom of the strip-shaped horizontal plate. The electric telescopic rod is powered by an external power source. The movable rod of the electric telescopic rod passes through the bottom of the strip-shaped horizontal plate and is fixedly connected to a movable plate. The movable plate is moved by the telescopic movement.

[0010] Preferably, the top of the movable plate is provided with multiple top rods arranged in a rectangular shape. The top ends of the top rods pass through the bottom of the template and are fixedly connected to a push plate. The push plate is located in the molding cavity. The movable plate drives the multiple top rods to move up and down, and the top rods drive the push plate to move. When the gel eye patch in the molding cavity is formed, the push plate moves up and pushes the formed gel eye patch in the molding cavity upward, so that the staff can easily pick up the formed gel eye patch.

[0011] Preferably, the top of the inner wall of the U-shaped bracket is provided with a clearance hole a for the top rod to pass through, and the bottom of the electric heating plate is provided with a clearance hole b for the top rod to pass through, so as to ensure that the top rod can move up and down smoothly and avoid obstructing the movement of the top rod.

[0012] Preferably, the air-cooling component includes a rectangular air inlet pipe fixedly connected to the top of the upper mold. The rectangular air inlet pipe is provided with three filter screens arranged equidistantly from left to right. The filter hole size of the three filter screens decreases from right to left to filter the incoming airflow to ensure its purity and prevent dust from adhering to the gel eye patch during the cooling process.

[0013] Preferably, an airflow pipe is provided on the left side of the rectangular air intake pipe, and a fan is provided inside the airflow pipe. The fan is powered by an external power source. The output end of the airflow pipe is connected to the air cavity through a guide pipe. Airflow is generated by the fan and guided into the air cavity through the guide pipe.

[0014] Preferably, the inner wall of the rectangular air intake pipe is provided with three U-shaped positioning blocks arranged equidistantly on both the upper and lower sides. The filter screen is inserted between the two U-shaped positioning blocks arranged opposite each other. The front side of the filter screen penetrates the inner wall of the rectangular air intake pipe and is fixedly connected with a handle, which makes it easy for the staff to disassemble and install the filter screen and facilitates later maintenance.

[0015] Preferably, the rear side of the U-shaped bracket is provided with a lifting component for controlling the lifting and lowering of the upper mold, which facilitates the removal of the eye patch. During air cooling, the upper mold is raised by 2-5mm, which helps to expel heat from between the upper mold and the template with the airflow. The lifting component includes a strip base plate fixedly connected to the bottom of the rear side of the U-shaped bracket. An L-shaped frame is provided in the middle of the top of the strip base plate. An electric cylinder is provided at the top of the L-shaped frame. The electric cylinder is powered by an external power source. The movable rod of the electric cylinder passes through the top of the L-shaped frame and is fixedly connected to the top of the upper mold. The upper mold is moved up and down by the electric cylinder. The top of the L-shaped frame is also provided with a controller for controlling the electric heating plate to maintain a constant temperature and controlling the operation of the fan, electric telescopic rod and electric cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1.

This design eliminates the need for additional heating and cooling equipment in traditional processes, significantly reducing production time and improving production efficiency.

[0018] 2. The rapid prototyping mold for this gel eye patch, through the design of the molding cavity and the avoidance groove, avoids contact between the upper mold and the uncured gel liquid, ensuring the stability and consistency of the gel during the molding process, thereby improving the molding quality and performance of the eye patch.

[0019] 3. The filter screen in the air-cooled part of the rapid prototyping mold for this gel eye patch can effectively filter the incoming airflow, ensuring the cleanliness of the airflow and preventing dust from adhering to the gel eye patch during molding, thereby reducing the risk of product damage caused by external contamination.

[0020] 4.

[0041] Furthermore, three U-shaped positioning blocks 45 are provided on the upper and lower sides of the inner wall of the rectangular air intake pipe 40, which are arranged at equal intervals. The filter screen plate 41 is inserted between the two U-shaped positioning blocks 45 arranged opposite to each other. The front side of the filter screen plate 41 penetrates the inner wall of the rectangular air intake pipe 40 and is fixedly connected with a handle, which makes it easy for staff to disassemble and install the filter screen plate 41 and facilitates later maintenance.

[0042] Furthermore, a lifting component 5 is provided on the rear side of the U-shaped bracket 10 to control the lifting and lowering of the upper mold 2, facilitating the removal of the eye patch. During air cooling, the upper mold 2 is raised by 2-5mm, which helps to expel heat from between the upper mold 2 and the template 11 with the airflow. The lifting component 5 includes a strip base plate 50 fixedly connected to the bottom of the rear side of the U-shaped bracket 10.

The upper mold 2 is moved up and down by the electric cylinder 52. A controller is also provided on the top of the L-shaped frame 51 to control the electric heating plate 12 to maintain constant temperature heating and to control the operation of the fan 43, the electric telescopic rod 31, and the electric cylinder 52.

[0043] In this embodiment, the rapid prototyping mold for gel eye patches is used as follows: First, gel liquid is injected into the molding cavity 110 of the template 11 to ensure uniform liquid distribution and to form the basic shape of the eye patch. The upper mold 2 is placed on top of the lower mold 1, aligning it with the molding cavity 110. Note that the clearance groove 21 of the upper mold 2 should be located directly above the molding cavity 110 to avoid contact with the gel liquid. Ensure that the electric heating plate 12 in the heating cavity 100 is in working condition to provide a suitable temperature for rapid curing of the gel material. After the gel material has been heated and cured, the air-cooling component 4 is activated. The fan 43 generates airflow in the airflow pipe 42. The airflow enters the air cavity 20 through the air guide pipe 44 and is blown out from the air outlet 22, rapidly cooling the contents of the molding cavity 110. The gel eye patch is formed quickly. During the cooling process, the lifting component 5 is used to fine-tune the upper mold 2, controlling the upper mold 2 to rise 2-5 mm during air cooling to facilitate heat dissipation. After cooling, the lifting component 5 controls the upper mold 2 to rise, and then the discharge component 3 is activated. The electric telescopic rod 31 drives the movable plate 32 to move, which drives the top rod 33 to rise. The push plate 34 pushes the formed gel eye patch out of the forming cavity 110, making it easy for the staff to take out the finished product. During use, the cleanliness of the filter screen plate 41 is checked regularly. If necessary, it is disassembled and cleaned by the handle to ensure that the airflow entering the air cavity 20 is pure. After use, the power of the electric heating plate 12, the fan 43, the electric telescopic rod 31, and the electric cylinder 52 is turned off to ensure that the equipment is in a safe state.
