Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a curing die. Background Technology

[0002] Currently, curing molds typically have light-transmitting holes on their outer sides, allowing light emitted from an external light source to pass through these holes and illuminate the colloid within the molding cavity, thus curing the colloid. However, the relatively hard material of these light-transmitting components results in poor sealing of the molding cavity formed by the light-transmitting components of the photocuring mold, leading to lower molding stability. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a curing mold to improve molding stability.

[0004] This application provides a curing mold, including:

[0005] The upper mold assembly has light-transmitting holes;

[0006] The lower mold assembly is appropriately matched with the upper mold assembly;

[0007] Two sets of light-transmitting components are respectively disposed on the upper mold assembly and the lower mold assembly, and form a molding cavity when the mold is closed. Each set of light-transmitting components includes a light-transmitting fixing component and a light-transmitting sealing component. The light-transmitting fixing component is disposed opposite to the light-transmitting hole. The light-transmitting fixing components of the two sets of light-transmitting components are respectively connected to the upper mold assembly and the lower mold assembly. The light-transmitting sealing components of the two sets of light-transmitting components are respectively disposed on the side of the corresponding light-transmitting fixing component away from the upper mold assembly and the side away from the lower mold assembly. The hardness of the light-transmitting sealing component is less than the hardness of the light-transmitting fixing component. The light-transmitting sealing component seals the molding cavity when the mold is closed. Light emitted by an external light source enters the molding cavity through the light-transmitting hole, the light-transmitting fixing component and the light-transmitting sealing component.

[0008] In some embodiments, the light-transmitting fixing component includes a light-transmitting fixing body and an adhesive layer. The light-transmitting fixing bodies of the two sets of light-transmitting components are respectively disposed on the upper mold assembly and the lower mold assembly. The light-transmitting fixing body is made of polycarbonate material. The adhesive layer is filled between the corresponding light-transmitting fixing body and the corresponding light-transmitting sealing component, and is respectively bonded to the corresponding light-transmitting fixing body and the corresponding light-transmitting sealing component.

[0009] In some embodiments, the light-transmitting seal is made of liquid silicone rubber.

[0010] In some embodiments, the light-transmitting component disposed on the upper mold assembly is provided with an air extraction hole, which passes through the light-transmitting fixing member and the light-transmitting sealing member disposed on the upper mold assembly in sequence along the direction from the upper mold assembly to the lower mold assembly, and the air extraction hole communicates with the molding cavity.

[0011] In some embodiments, the upper mold assembly is provided with a receiving hole, which is disposed opposite to and passes through the light-transmitting fixing member disposed on the upper mold assembly;

[0012] The curing mold also includes a connecting member, which is disposed in the receiving hole and detachably connected to the upper mold assembly. The connecting member is connected to the air extraction hole and the external air extraction component, respectively.

[0013] In some embodiments, both the upper mold assembly and the lower mold assembly include:

[0014] A template component, wherein the template component abuts against the corresponding light-transmitting fixing component;

[0015] Multiple pressure plates are spaced apart along the circumference of the light-transmitting fixing member. Each pressure plate abuts against the side of the light-transmitting fixing member away from the template member and is detachably connected to the template member to fix the light-transmitting fixing member to the template member.

[0016] In some embodiments, the light-transmitting component disposed on the upper mold assembly is provided with a glue-filling hole, the glue-filling hole passing through the light-transmitting fixing member and the light-transmitting sealing member disposed on the upper mold assembly in sequence along the direction from the upper mold assembly to the lower mold assembly, and the glue-filling hole communicating with the molding cavity;

[0017] The light-transmitting component also includes a rubber plug, which is used to be inserted into the end of the glue-filling hole away from the molding cavity.

[0018] In some embodiments, the light-transmitting fixing member disposed on the upper mold assembly is provided with a retaining groove, the retaining groove is located at one end of the light-transmitting fixing member away from the light-transmitting sealing member and is disposed on the groove wall of the glue-filling hole, and the retaining groove communicates with the glue-filling hole;

[0019] The rubber stopper includes a rubber stopper body and a retaining body. The retaining body protrudes from the outside of the rubber stopper body and is connected to the rubber stopper body. The rubber stopper body is used to be inserted into the glue filling hole, and the retaining body is used to be inserted into the retaining groove to retain and connect the light-transmitting fixing member.

[0020] In some embodiments, the cross-sectional area of ​​the light-transmitting hole gradually decreases along the outer side of the upper mold assembly toward the molding cavity.

[0021] In some embodiments, the light-transmitting seal has a molding groove located on the side of the light-transmitting seal opposite to the light-transmitting fixing member.

[0022] During operation, the upper and lower mold components of the aforementioned curing mold are closed, and the two sets of light-transmitting components enclose the molding cavity. All the gas in the molding cavity is extracted through the vent hole, and then the colloid is injected into the molding cavity through the injection hole. Since the hardness of the light-transmitting sealing component in the light-transmitting component is less than that of the light-transmitting fixing component, the light-transmitting sealing component can deform when enclosing the molding cavity to seal the molding cavity. This allows the colloid to be stably filled into the molding cavity, which helps maintain the sealing of the molding cavity and prevents the colloid from leaking out from the gaps in the molding cavity due to poor sealing. This allows the colloid in the molding cavity to solidify stably under the light emitted by the external light source, thereby improving the molding stability. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0033] Please see Figure 1 and Figure 2 This application provides a curing mold 100, including an upper mold assembly 10, a lower mold assembly 20 and two sets of light-transmitting components 30, to cure the colloid under the illumination of an external light source.

[0034] Please continue reading. Figure 1 and Figure 2The upper mold assembly 10 is provided with a light-transmitting hole 11, and the lower mold assembly 20 is arranged opposite to the upper mold assembly 10 and fits together. Two sets of light-transmitting components 30 are respectively arranged on the upper mold assembly 10 and the lower mold assembly 20, and form a molding cavity 31 when the mold is closed. Each set of light-transmitting components 30 includes a light-transmitting fixing part 32 and a light-transmitting sealing part 33. The light-transmitting fixing parts 32 of the two sets of light-transmitting components 30 are respectively connected to the upper mold assembly 10 and the lower mold assembly 20. The light-transmitting sealing parts 33 of the two sets of light-transmitting components 30 are respectively arranged on the side of the corresponding light-transmitting fixing part 32 away from the upper mold assembly 10 and the side away from the lower mold assembly 20. The hardness of the light-transmitting sealing part 33 is less than the hardness of the light-transmitting fixing part 32. The light-transmitting sealing part 33 seals the molding cavity 31 when the mold is closed. The light emitted by the external light source (not shown) enters the molding cavity 31 through the light-transmitting hole 11, the light-transmitting fixing part 32 and the light-transmitting sealing part 33.

[0035] When the curing mold 100 is in operation, by setting the hardness of the light-transmitting sealing element 33 to be less than that of the light-transmitting fixing element 32, the light-transmitting sealing element 33 can deform when surrounding and forming the molding cavity 31 to seal the molding cavity 31. This allows the colloid to be stably filled into the molding cavity 31, which helps to maintain the sealing performance of the molding cavity 31 and prevents the colloid from leaking out of the gaps in the molding cavity 31 due to poor sealing performance. This allows the colloid in the molding cavity 31 to be stably cured under the light emitted by the external light source, thereby improving the molding stability.

[0036] Please see Figure 2 and Figure 3 In some embodiments, the light-transmitting fixing member 32 includes a light-transmitting fixing body 321 and an adhesive layer 322. The light-transmitting fixing bodies 321 of the two sets of light-transmitting components 30 are respectively disposed on the upper mold component 10 and the lower mold component 20. The light-transmitting fixing body 321 is made of polycarbonate material. The adhesive layer 322 fills between the corresponding light-transmitting fixing body 321 and the corresponding light-transmitting sealing member 33, and is respectively bonded to the corresponding light-transmitting fixing body 321 and the corresponding light-transmitting sealing member 33.

[0037] Thus, by setting the adhesive layer 322 to fill between the corresponding light-transmitting fixing body 321 and the corresponding light-transmitting sealing element 33, the adhesive layer 322 can stably bond the light-transmitting fixing body 321 and the light-transmitting sealing element 33 together, while avoiding the use of other connection structures that would affect the high light transmittance characteristics of the light-transmitting fixing body 321 and the light-transmitting sealing element 33. In addition, by setting the material of the light-transmitting fixing body 321 to polycarbonate, the high light transmittance of polycarbonate allows light emitted from an external light source to shine through the light-transmitting fixing body 321 into the molding cavity 31. The easy processing characteristics of polycarbonate make it easy to process the light-transmitting fixing body 321 into a preset structure. In particular, for the complex structure of the light-transmitting fixing body 321, the high hardness of polycarbonate improves the service life of the light-transmitting fixing body 321.

[0038] In some embodiments, the material of the light-transmitting seal 33 is liquid silicone rubber, which makes the hardness of the light-transmitting seal 33 less than the hardness of the light-transmitting fixing body 321. This is beneficial for the light-transmitting seal 33 to deform during the formation of the molding cavity 31. In addition, by utilizing the high transparency of liquid silicone rubber, light emitted by an external light source can be irradiated into the molding cavity 31 through the light-transmitting seal 33.

[0039] Please see Figure 2 and Figure 4 In some embodiments, the light-transmitting component 30 disposed on the upper mold assembly 10 is provided with an air extraction hole 34. The air extraction hole 34 passes through the light-transmitting fixing member 32 and the light-transmitting sealing member 33 disposed on the upper mold assembly 10 in sequence along the direction from the upper mold assembly 10 to the lower mold assembly 20, and the air extraction hole 34 is connected to the molding cavity 31.

[0040] Thus, by setting the air extraction hole 34 to connect with the molding cavity 31, all the gas in the molding cavity 31 can be extracted through the air extraction hole 34 before the colloid is injected into the molding cavity 31. This prevents the gas in the molding cavity 31 from mixing with the colloid injected into the molding cavity 31, which would cause small air bubbles to form after the colloid is cured. This is beneficial to improving the product quality of the cured colloid.

[0041] Please see Figure 4 In some embodiments, the upper mold assembly 10 is provided with a receiving hole 12, which is disposed opposite to and passes through the light-transmitting fixing member 32 disposed on the upper mold assembly 10. The curing mold 100 also includes a connecting member 40, which is disposed in the receiving hole 12 and detachably connected to the upper mold assembly 10. The connecting member 40 is connected to the air extraction hole 34 and the external air extraction member, respectively.

[0042] Thus, by connecting the connecting member 40 to both the evacuation hole 34 and the external evacuation member, the external evacuation member can stably extract gas from the molding cavity 31, ensuring that all gas in the molding cavity 31 is extracted. Furthermore, by detachably connecting the connecting member 40 to the upper mold assembly 10, the connecting member 40 can be removed after evacuation, allowing light emitted from the external light source to illuminate the light-transmitting fixing member 32 through the receiving hole 12, increasing the light-illuminated area of ​​the light-transmitting fixing member 32 and improving curing efficiency.

[0043] Please see Figure 4 and Figure 5In some embodiments, both the upper mold assembly 10 and the lower mold assembly 20 include a template member 13 and a plurality of pressure plate members 14. The template member 13 abuts against a corresponding light-transmitting fixing member 32. The plurality of pressure plate members 14 are arranged at intervals along the circumference of the light-transmitting fixing member 32, and each pressure plate member 14 abuts against the side of the light-transmitting fixing member 32 opposite to the template member 13, and is detachably connected to the template member 13 to fix the light-transmitting fixing member 32 to the template member 13. In this embodiment, "plural" refers to two or more.

[0044] In this way, by abutting the multiple pressure plates 14 at different positions of the light-transmitting fastener 32 and connecting them to the template 13, the pressure plates 14 can fix the light-transmitting fastener 32 to the template 13, and make the light-transmitting fastener 32 and the template 13 form a split structure, which makes it easy to replace different light-transmitting fasteners 32 according to production needs.

[0045] Please see Figure 4 In some embodiments, the light-transmitting component 30 disposed on the upper mold assembly 10 is provided with a glue-filling hole 35. The glue-filling hole 35 passes through the light-transmitting fixing member 32 and the light-transmitting sealing member 33 disposed on the upper mold assembly 10 in sequence along the direction from the upper mold assembly 10 to the lower mold assembly 20. The glue-filling hole 35 communicates with the molding cavity 31. The light-transmitting component 30 also includes a glue plug 36, which is used to be inserted into the end of the glue-filling hole 35 away from the molding cavity 31.

[0046] Thus, by connecting the glue-filling hole 35 to the molding cavity 31, the external glue-filling component can stably inject the glue into the molding cavity 31 through the glue-filling hole 35, ensuring that the glue is stably filled into the molding cavity 31. Furthermore, before injecting the glue into the molding cavity 31, a glue plug 361 is inserted at the end of the glue-filling hole 35 furthest from the molding cavity 31, creating a sealed environment in the molding cavity 31. This facilitates the extraction of gas from the molding cavity 31 by an external vacuum component. After injecting the glue into the molding cavity 31, the glue plug 361 is inserted at the end of the glue-filling hole 35 furthest from the molding cavity 31 to prevent the glue from overflowing from the glue-filling hole 35 due to external interference, ensuring that the glue is stably filled into the molding cavity 31.

[0047] In some embodiments, the rubber stopper 36 is made of liquid silicone rubber.

[0048] Thus, by setting the material of the rubber stopper 36 to liquid silicone rubber, the high transparency of liquid silicone rubber is utilized to prevent the rubber stopper 36 from affecting the curing of the colloid in the molding cavity 31 due to its lack of light transmittance, which is beneficial to maintaining the high light transmittance of the curing mold 100.

[0049] Please continue reading. Figure 4In some embodiments, the light-transmitting fixing member 32 disposed on the upper mold assembly 10 is provided with a retaining groove 323. The retaining groove 323 is located at the end of the light-transmitting fixing member 32 away from the light-transmitting sealing member 33 and is disposed on the groove wall of the glue-filling hole 35. The retaining groove 323 communicates with the glue-filling hole 35. The glue plug member 36 includes a glue plug body 361 and a retaining body 362. The retaining body 362 protrudes from the outside of the glue plug body 361 and is connected to the glue plug body 361. The glue plug body 361 is used to be inserted into the glue-filling hole 35, and the retaining body 362 is used to be inserted into the retaining groove 323 to retain and connect the light-transmitting fixing member 32.

[0050] Thus, by inserting the retaining body 362 into the retaining groove 323, the retaining body 362 can stably retain the light-transmitting fixing member 32, and the rubber plug 361 can stably seal the glue filling hole 35, preventing the rubber plug 36 from falling out of the glue filling hole 35 due to external interference.

[0051] Please see Figure 3 In some embodiments, the cross-sectional area of ​​the light-transmitting hole 11 gradually decreases along the outer side of the upper mold assembly 10 towards the molding cavity 31, which can increase the light-receiving area of ​​the curing mold 100 and facilitate the concentration of light to the light-transmitting fixing member 32, thereby improving the curing efficiency of the colloid.

[0052] Please continue reading. Figure 3 In some embodiments, the light-transmitting seal 33 has a molding groove 331, which is located on the side of the light-transmitting seal 33 away from the light-transmitting fixing member 32.

[0053] Thus, by opening a molding groove 331 on the light-transmitting seal 33, the colloid injected into the molding cavity 31 can flow into the molding groove 331, so that the colloid can be cured in the molding groove 331 and form a preset structure, thereby improving the molding accuracy of the colloid.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
