Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for producing a thermometer shell. Background Technology

[0002] As society ages, the needs of elderly people with visual impairments or poor eyesight are becoming increasingly prominent in their daily lives. They often encounter difficulties using conventional thermometers because they cannot clearly see the scale. To solve this problem, it is necessary to design a thermometer casing with a convex lens module, as detailed below. Figure 1 As shown, the processing of outer shell products generally adopts a slider core-pulling molding structure. However, due to the small size of the thermometer and the fact that the design size of the thermometer shell should not be too large (i.e., the thickness of the thermometer shell is small), coupled with the fact that the thermometer is a long strip structure, the slider of the mold using the slider core-pulling structure is very likely to collide with the inwardly protruding flange of the mold to prevent liquid from flowing out. In addition, the pulling force on the slider in the core-pulling molding structure is relatively large, which may cause the flange of the mold to be damaged. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a thermometer shell production mold, which can solve the problem of the slider damaging the mold during the core pulling process.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A thermometer casing manufacturing mold, comprising:

[0006] A first template, wherein one side of the first template is provided with a first forming groove, the first forming groove extending to the end face of the first template;

[0007] The second template has a second forming groove on one side, which extends to the end face of the second template.

[0008] slider;

[0009] The first molding groove and the second molding groove are arranged opposite to each other. The first molding groove has a visual area on its groove wall and / or the second molding groove has a visual area on its groove wall. The visual area is a first milled plane or a first arc surface. The first molding groove and the second molding groove are assembled to form a molding cavity for molding the thermometer shell. The slider can move in the molding cavity and there is a gap between the slider and the molding cavity. The outer wall of the slider facing the visual area is a concave surface, a plane, or a second arc surface with a curvature smaller than the first arc surface.

[0010] By adopting the above scheme, the first forming groove extends to the end face of the first template and the second forming groove extends to the end face of the second template. That is, no flange is set at the first forming groove and the second forming groove, thereby ensuring that there will be no destructive collision with the first template and the second template during the movement of the slider.

[0011] The first forming groove and / or the second forming groove are provided with a visual area. The visual area is provided with a first milled plane to facilitate the installation of a convex lens on the formed shell, or the visual area is a first arc surface to directly form a convex lens structure on the shell. The outer wall of the slider facing the first arc surface is a concave surface, a plane, or a second arc surface with a curvature smaller than the first arc surface. This allows for the installation of a convex lens on the outer surface of the formed shell, or the first arc surface to cooperate with the convex lens to form a convex lens, thereby facilitating the calibration of the thermometer and making it easier to observe the thermometer scale.

[0012] Furthermore, the visual area is located on the first template, the visual area is a first arc surface, and the second forming groove has a second milled plane on its groove wall.

[0013] By adopting the above scheme, the setting of the second milling plane facilitates the placement of the shell after molding and prevents the shell from rolling and falling. The second milling plane is set opposite to the first arc surface so that the shell does not roll when it is placed after molding, while presenting the visual area above or diagonally above the shell to achieve the effects of anti-scratching and easy observation.

[0014] Furthermore, the first template is provided with a clearance hole for the material conveying pipeline to pass through, and a pipe groove is provided between the clearance hole and the first forming groove;

[0015] And / or, the second template is provided with a clearance hole for the material conveying pipe to pass through, and a pipe groove is provided between the clearance hole and the second forming groove.

[0016] By adopting the above scheme, the clearance hole allows the material conveying pipeline to pass directly through the template without bypassing the template or making complex layout adjustments, thus simplifying the mold structure and production process. Furthermore, the direct connection method reduces material loss and heat dissipation during conveying, improving molding efficiency and product quality stability. The pipe groove facilitates the installation of pipelines, making it easy to transfer liquid material from the conveying pipeline to the first and second molding tanks.

[0017] Furthermore, one end of the tube groove is connected to the clearance hole, and the other end is connected to the end of the first forming groove away from the slider extraction movement direction, or the other end is connected to the end of the second forming groove away from the slider extraction movement direction.

[0018] By adopting the above scheme, this design of the tube channel helps guide the material smoothly from the conveying pipeline into the first and second forming tanks, and flows along the path of the tube channel to the far end of the forming tank. This orderly flow can reduce turbulence and uneven spraying of materials during the forming process, improving the forming quality and consistency of the product. Furthermore, due to the guiding effect of the tube channel, the material can be more evenly distributed in the forming tank, thereby reducing forming defects such as bubbles, shrinkage cavities, and material shortages caused by uneven material distribution.

[0019] Furthermore, the visual area is a first arc surface, and the outer wall of the slider facing the first arc surface is a second arc surface with a smaller arc radius than the first arc surface. The radius of the arc of the first arc surface section is set as X, and the radius of the arc of the second arc surface section is set as Y, wherein the ratio of X to Y is between one-half and one-fifth.

[0020] By adopting the above scheme, the curvature of the first arc surface is greater than that of the second arc surface to ensure that the shell processed by the first and second templates forms a larger curvature. The greater the curvature, the stronger the light-converging ability, which may produce a more obvious magnification effect. The above ratio achieves the best magnification effect. If the curvature of the second arc surface is too large, it will affect the magnification effect and require a corresponding adjustment of the curvature of the first arc surface, which may lead to an excessively convex outer surface, thus affecting the strength of the shell processed by the first and second templates. If the curvature of the second arc surface is too small, it will be inconvenient for the installation of the thermometer.

[0021] Furthermore, the first template is provided with a plurality of first forming grooves, and the second template is provided with a plurality of second forming grooves, and the number and position of the first forming grooves and the second forming grooves are corresponding.

[0022] By adopting the above scheme, multiple first forming tanks and second forming tanks are set up to improve production efficiency.

[0023] Furthermore, the first template and the second template are provided with positioning structures.

[0024] By adopting the above solution, the positioning structure ensures precise alignment of the first and second mold plates during mold closing, avoiding dimensional deviations and shape distortions caused by misalignment, thereby improving product precision and quality. Through the fixing and supporting function of the positioning structure, the mold remains stable during the molding process, reducing molding defects caused by vibration or deformation.

[0025] Furthermore, the positioning structure includes a first positioning structure and a second positioning structure. The first positioning structure is a positioning groove, and the second positioning structure is a positioning protrusion corresponding to the positioning groove. One of the first positioning structure and the second positioning structure is located on the first template, and the other is located on the second template.

[0026] By adopting the above scheme, the matching design of the positioning groove and the positioning protrusion ensures precise alignment of the first and second templates during the mold closing process. This design reduces dimensional deviations and shape distortions caused by template misalignment, thereby improving product accuracy and quality. The positioning structure not only achieves precise alignment between templates but also increases the overall stability of the mold through physical contact. During the molding process, the mold can maintain a stable shape and position, reducing molding defects caused by vibration or deformation.

[0027] Furthermore, the first template is provided with a first reference mark, and the second template is provided with a second reference mark, for reference to the assembly relationship between the first template and the second template.

[0028] By adopting the above solution, the reference markers provide assembly personnel with intuitive visual guidance, making the assembly process simpler and faster. Assembly personnel only need to follow the guidance of the reference markers to assemble, eliminating the need for complex measurements and adjustments, thus improving assembly efficiency.

[0029] Furthermore, the first template is provided with liquid cooling pipes and / or the second template is provided with liquid cooling pipes.

[0030] By employing the above solution, the liquid cooling system rapidly dissipates heat generated inside the mold through the circulating coolant, achieving highly efficient heat dissipation and preventing deformation, cracking, or damage caused by overheating. Stable mold temperature helps maintain product dimensional stability and consistency. The liquid cooling system can precisely control the temperature distribution of the mold, reducing dimensional deviations and shape distortions caused by temperature changes, thereby improving product quality and precision.

[0031] In summary, the thermometer shell production mold provided by this utility model has the following technical effects:

[0032] 1. The first forming groove extends to the end face of the first template, and the second forming groove extends to the end face of the second template. That is, no flange is provided at the first forming groove and the second forming groove, so as to ensure that there will be no destructive collision with the first template and the second template during the movement of the slider.

[0033] 2. A first milled plane or a first arc surface is set in the visual area. When a first milled plane is set in the visual area, it facilitates the installation of a convex lens on the formed shell. The presence of the milled plane allows the convex lens to be stably installed in the predetermined position, and ensures the accuracy and reliability of the installation.

[0034] When the visual area is designed as a first curved surface, the convex lens structure can be directly formed on the housing. This design reduces additional processing steps and installation procedures, improving production efficiency and overall product performance.

[0035] 3. The outer wall of the slider facing the first arc surface is designed as a concave surface, a flat surface, or a second arc surface with a smaller curvature than the first arc surface. This design allows for easy alignment with a convex lens mounted on the outer surface of the molded outer shell or the first arc surface to create a convex lens effect. The magnifying effect of the convex lens makes the thermometer scale more clearly visible, facilitating user observation. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] See Figures 2-5 This utility model discloses a thermometer shell production mold, including: a first template 1, a second template 2, and a slider 3. One side of the first template 1 is provided with a first forming groove 11, which extends to the end face of the first template 1. One side of the second template 2 is provided with a second forming groove 21, which extends to the end face of the second template 2. The first forming groove 11 and the second forming groove 21 are arranged opposite to each other. The first forming groove 11 has a visual area 12 on its groove wall, and / or the second forming groove 21 has a visual area 12 on its groove wall. The visual area 12 is a first milled plane or a first arc surface. The first forming groove 11 and the second forming groove 21 are combined to form a forming cavity for forming the thermometer shell 9. The slider 3 can move within the forming cavity, and there is a gap between the slider 3 and the forming cavity. The outer wall of the slider 3 facing the first arc surface is a concave surface, a plane, or a second arc surface 31 with a curvature smaller than the first arc surface.

[0048] Specifically, one side of the first template 1 is provided with a first forming groove 11, which extends to the end face of the first template 1. One side of the second template 2 is provided with a second forming groove 21, which extends to the end face of the second template 2. During assembly, the first template 1 and the second template 2 are assembled with the first forming groove 11 and the second forming groove 21 facing each other, so that the first forming groove 11 and the second forming groove 21 are joined together to form a forming cavity. The slider 3 can move within the forming cavity, and there is a gap between the slider 3 and the forming cavity. This gap is the forming area during the processing of the outer shell 9. The specific size of the gap can be adjusted according to the thermometer to be matched. The groove wall of the first forming groove 11 has a visual area 12 and / or the groove wall of the second forming groove 21 has a visual area 12. The position of the visual area 12 is set optimally according to the position of the thermometer scale line so that after the outer shell 9 is formed, the portion of the outer shell 9 corresponding to the visual area 12 can observe the specific value of the thermometer inside the outer shell 9. The visual area 12 can be either a first milled plane or a first arc surface. When the visual area 12 is a first milled plane, the outer surface of the shell 9, which is machined using a mold, corresponding to the position of the visual area 12 is also a plane. A convex lens can be installed at the plane position of the shell 9 to achieve the effect of magnifying the scale of the thermometer assembled inside the shell 9. When the visual area 12 is a first arc surface, the outer surface machined corresponding to the visual area 12 during the forming of the shell 9 has an arc structure. Thus, the position of the shell 9 corresponding to the visual area 12 directly has a convex lens structure, thereby achieving the effect of magnifying the scale of the thermometer assembled inside the shell 9. The outer wall of the slider 3 facing the visual area 12 can be a concave surface, a plane, or a second arc surface 31 with a curvature smaller than the first arc surface. The slider 3 facing the visual area 12 can be specifically set to a concave surface, a plane, or a second arc surface 31 with a curvature smaller than the first arc surface, as long as it can satisfy the requirement that the shell 9 corresponding to the visual area 12 has a convex lens structure and can satisfy the assembly of the thermometer.

[0049] In this embodiment, the visual area 12 is provided on the first template 1, the visual area 12 is a first arc surface, and the second forming groove 21 has a second milled plane 22 on its groove wall.

[0050] Specifically, during the processing of the outer shell 9, the portion of the outer shell 9 corresponding to the second milling plane 22 is also a plane, which facilitates the placement of the formed outer shell 9 and prevents the outer shell 9 from rolling. The second milling plane 22 is set opposite to the first arc surface so that the formed outer shell 9 does not roll when placed, while presenting the visual area 12 above or diagonally above the outer shell 9 to achieve the effects of anti-scratching and easy observation.

[0051] In some embodiments, in order to facilitate the setting of the material conveying pipeline, the first template 1 is provided with a clearance hole 4 for the material conveying pipeline to pass through, and a pipe groove 5 is provided between the clearance hole 4 and the first forming groove 11; and / or, the second template 2 is provided with a clearance hole 4 for the material conveying pipeline to pass through, and a pipe groove 5 is provided between the clearance hole 4 and the second forming groove 21.

[0052] Specifically, the clearance hole 4 can be set on the first template 1 and / or the second template 2. The designer can set the position and number of clearance holes 4 as needed, and there is no limitation here. The tube groove 5 corresponding to the clearance hole 4 can also be set on the first template 1 and / or the second template 2. The tube groove 5 only needs to be able to connect the clearance hole 4 with the first forming groove 11 / second forming groove 21. In practical applications, the material conveying pipeline passes through the clearance hole 4, is laid in the tube groove 5, and extends all the way to the first forming groove 11 / second forming groove 21.

[0053] Furthermore, one end of the tube groove 5 is connected to the clearance hole 4, and the other end is connected to the end of the first forming groove 11 away from the sliding block 3 in the direction of withdrawal movement, or the other end is connected to the end of the second forming groove 21 away from the sliding block 3 in the direction of withdrawal movement.

[0054] Specifically, one end of the tube groove 5 is connected to the clearance hole 4, and the other end of the tube groove 5 is connected to the end of the first forming groove 11 away from the sliding block 3 in the direction of its withdrawal movement, or the other end is connected to the end of the second forming groove 21 away from the sliding block 3 in the direction of its withdrawal movement. That is, the other end of the tube groove 5 is connected to the end away from the sliding block 3 in the direction of its withdrawal movement, so as to facilitate material feeding and thus ensure the forming quality of the outer shell 9.

[0055] See Figures 2-6 As shown, in some embodiments, the visual area 12 is a first arc surface, and the outer wall of the slider 3 facing the first arc surface is a second arc surface 31 with a smaller arc radius than the first arc surface. The radius of the arc of the first arc surface section is set as X, and the radius of the arc of the second arc surface 31 section is set as Y, where the ratio of X to Y is between one-half and one-fifth.

[0056] Specifically, the curvature of the first arc surface is greater than that of the second arc surface 31 to ensure that the outer shell 9 processed by the first template 1 and the second template 2 has a larger curvature. The greater the curvature, the stronger the light-converging ability, which may produce a more obvious magnification effect. The above ratio achieves the best magnification effect. If the curvature of the second arc surface 31 is too large, it will affect the magnification effect and require a corresponding adjustment of the curvature of the first arc surface, which may result in an excessively convex outer surface, thus affecting the strength of the outer shell 9 processed by the first template 1 and the second template 2. If the curvature of the second arc surface 31 is too small, it will be inconvenient for the installation of the thermometer.

[0057] In this embodiment, X is 11.5cm and Y is 31cm. After verification, the shell produced using this ratio has the best magnification effect and can be adapted to common thermometers on the market.

[0058] In some embodiments, in order to improve production efficiency, the first template 1 is provided with a plurality of first forming grooves 11, and the second template 2 is provided with a plurality of second forming grooves 21, and the number and position of the first forming grooves 11 and the second forming grooves 21 are corresponding.

[0059] In some embodiments, the first template 1 and the second template 2 are provided with positioning structures to facilitate the positioning of the first template 1 and the second template 2.

[0060] Specifically, the positioning structure can be a positioning pin and positioning hole, a guide post and guide sleeve, a wedge-shaped positioning block, or a magnetic positioning device, etc., and is not limited here. The positioning structure ensures that the first mold plate 1 and the second mold plate 2 are precisely aligned when the mold is closed, avoiding dimensional deviations and shape distortions caused by misalignment, thereby improving the precision and quality of the product. Through the fixing and supporting effect of the positioning structure, the mold can remain stable during the molding process, reducing molding defects caused by vibration or deformation.

[0061] In this embodiment, the positioning structure includes a first positioning structure 61 and a second positioning structure 62. The first positioning structure 61 is a positioning groove, and the second positioning structure 62 is a positioning protrusion corresponding to the positioning groove. One of the first positioning structure 61 and the second positioning structure 62 is located on the first template 1, and the other is located on the second template 2.

[0062] In some embodiments, in order to ensure the correspondence between the first template 1 and the second template 2 during assembly, the first template 1 is provided with a first reference mark 71 and the second template 2 is provided with a second reference mark 72, for reference to the assembly relationship between the first template 1 and the second template 2.

[0063] Specifically, the form or structure of the first reference mark 71 and the second reference mark 72, such as engraved lines, raised areas, grooves, or marking points, is not limited here, nor is their placement restricted. The goal is to provide assembly personnel with intuitive visual guidance, making the assembly process simpler and faster. Assembly personnel only need to follow the guidance of the reference marks for assembly, eliminating the need for complex measurements and adjustments, thus improving assembly efficiency.

[0064] In this embodiment, the first reference mark 71 and the second reference mark 72 are engraved structures. The first reference mark 71 is located at the first positioning structure 61, and the second reference mark 72 is located at the second positioning structure 62. At the same time, the assembly relationship between the first template 1 and the second template 2 is also compared during the positioning process.

[0065] In some embodiments, in order to ensure the temperature stability of the first template 1 and the second template 2 during the processing, the first template 1 is provided with a liquid cooling pipe 8 and / or the second template 2 is provided with a liquid cooling pipe 8.

[0066] Specifically, the liquid cooling line 8 rapidly removes heat generated inside the mold through circulating coolant, achieving efficient heat dissipation and preventing deformation, cracking, or damage caused by overheating. Stable mold temperature helps maintain product dimensional stability and consistency. The liquid cooling line 8 precisely controls the mold's temperature distribution, reducing dimensional deviations and shape distortions caused by temperature changes, thereby improving product quality and precision.

[0067] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
