Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a modular mold capable of manufacturing various silicone button gaskets. Background Technology

[0002] Silicone products are widely used in many fields due to their good chemical stability, biocompatibility, electrical insulation, and plasticity. However, because of their poor machinability, silicone products are generally only manufactured using molds. Button washers are silicone products that are used with buttons, serving to seal the buttons and increase their resilience. Since there are many types of buttons, there are also many types of button washers.

[0003] Most molds can only be used to manufacture one type of product, such as the "Silicone Cake Mold (CN221430040U)" developed by Dongguan Ruifeng Silicone Products Co., Ltd., and the "Silicone Ice Cream Mold with Combination Function (CN210630583U)" developed by Suzhou Aoke Rubber Technology Co., Ltd. These molds can only produce one type of product, which cannot meet our needs. Furthermore, the manufacturing cost of these molds is high, making it impractical to develop and manufacture a mold for each product. Therefore, we urgently need a robust and reliable mold that can be used to manufacture various silicone button washers. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a modular mold that can manufacture a variety of silicone button gaskets, in order to solve the technical problem that existing silicone molds can only produce a single silicone product and cannot be combined or used to produce multiple models of silicone products at the same time.

[0005] According to the technical solution provided in the embodiments of this application, a combined mold capable of manufacturing various silicone button washers includes several upper mold plates and a lower mold plate. The upper mold plates are provided with several threaded guide posts that pass through the lower mold plate in sequence and are stacked on the lower mold plate. Each threaded guide post is screwed with a corresponding Torx nut, thereby flattening and fixing the upper mold plates to the lower mold plate. The number of stacked upper mold plates is an integer multiple of the height of the washer mold. The lower mold plate has several circular grooves arranged side by side and spaced apart on its surface, while the upper mold plate has corresponding circular holes of the same diameter, so that the circular holes and the grooves form an upward-opening groove after the upper mold plates are stacked, for filling with silicone liquid.

[0006] Furthermore, a positioning pin protrudes from the center of the groove and engages with a positioning hole at the bottom of the washer mold, so that the washer mold is positioned and engaged within the groove.

[0007] Furthermore, the thickness of the upper plate of the mold is 0.05 inches.

[0008] Furthermore, the upper plate of the mold has several corresponding mounting holes on both sides and in the middle, and the mounting holes are arranged side by side and spaced apart along the horizontal longitudinal direction.

[0009] Furthermore, both the upper mold plate and the lower mold plate are rectangular structures.

[0010] Furthermore, both the upper mold plate and the lower mold plate are made of acrylic material.

[0011] In summary, the beneficial effects of this application are as follows: First, a single mold can manufacture multiple types of button washers. By stacking different numbers of mold plates and changing different types of washer molds, different types of button washers can be produced. The manufacturing process is simple, convenient, reliable, and highly applicable. Second, by selecting and installing different washer molds according to actual production needs, different quantities of various button washers can be produced in the same batch, which facilitates production planning and shortens the production cycle. 3. Nine hand-tightened Torx nuts can be installed, evenly distributed across the entire upper plate surface of the mold. In addition to their fixing function, they can also be used to flatten the mold plate, making it as flat as possible to eliminate gaps between the plates. Fourth, it is easy to demold. After the product is finished, simply unscrew the screws and remove the mold plate one by one to easily remove the product from the mold, effectively reducing the risk of damaging the final product. Fifth, the mold only requires acrylic sheets, shelf-type fasteners, and a machining center and ultrasonic welding equipment to make. It has a low production threshold, short production cycle, and is convenient for large-scale promotion and use. Attached Figure Description

Detailed Implementation

[0013] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] A modular mold capable of manufacturing various silicone button gaskets, its structure as follows: Figures 1-3 As shown, a mold set includes several upper mold plates 1 and one lower mold plate 2. The upper mold plates 1 have several mounting holes 11 on both sides and in the middle. There are three mounting holes 11 in total, and the mounting holes 11 are arranged side by side and spaced apart along the horizontal longitudinal direction. The lower mold plate 2 is welded with several threaded guide posts 21, so that each upper mold plate 1 passes through the mounting holes 11 and then passes through the threaded guide posts 21 on the lower mold plate 2, and is then stacked on the lower mold plate 2. Each threaded guide post 21 is screwed with a corresponding pendant nut 4, so that each pendant nut 4 flattens and fixes the upper mold plates 1 on the lower mold plate 2, so that the round holes 12 and grooves 22 on the stacked upper mold plates 1 and lower mold plate 2 form an upward-opening groove. Different types of gasket molds 3 are positioned and clamped in the groove, so that the groove is filled with silicone liquid and solidified at room temperature. Thus, one mold set can produce multiple types of silicone gasket buttons at the same time, thereby improving the production efficiency of gaskets.

[0016] like Figure 1 and Figure 2 As shown, the thickness of a single mold upper plate 1 is 0.05 inches. This thickness is set by combining the effective working height of each type of gasket mold 3 with the mold material and design dimensions. When the thickness is less than 0.05 inches, the mold upper plate 1 will have insufficient strength, resulting in excessive bending of the plate surface. At the same time, the number of stacked mold upper plates 1 should be an integer of the unit thickness that can be divided into the effective working height of the gasket mold 3 to avoid excess height, which would affect the production quality of the silicone gasket button.

[0017] like Figure 1 and Figure 3As shown, the lower mold plate 2 is made of acrylic material and has a rectangular structure plate. Several circular grooves 22 are arranged side by side and spaced apart on its surface. The grooves 22 are evenly distributed on the surface of the lower mold plate 2 in a "4×8" pattern. The upper mold plates 1 have corresponding circular holes 12 of the same diameter, so that the circular holes 12 and grooves 22 on the stacked upper mold plates 1 form an upward-opening groove for filling with silicone liquid.

[0018] like Figure 3 As shown, the positioning pin 23 is protruding and located in the middle of the groove 22. The positioning pin 23 is integrally machined with the mold lower plate 2. At the same time, the bottom of the washer is provided with a positioning hole of corresponding diameter so that the positioning pin 23 can be engaged in the positioning hole, thereby positioning and fixing the washer mold 3 in the groove 22. The diameter of the bottom of the washer mold 3 is adapted to the diameter of the groove 22.

[0019] Washer molds 3 have now been developed in dozens of types, with some typical forms shown below. Figure 4 As shown.

[0020] The silicone used in this application for the gasket mold 3 is preferably similar to SI598BK decontamination silicone, which is a filling material with properties such as being initially liquid, having a certain tension, and being able to solidify when exposed to a natural environment at room temperature and pressure.

[0021] The working principle of this utility model's modular mold capable of manufacturing various silicone button gaskets is as follows: A set of modular silicone button gasket molds 3 consists of several upper mold plates 1, one lower mold plate 2, up to thirty-two various types of gasket molds 3, and nine hand-tightened Torx nuts 4. The number of upper mold plates 1 is determined by the height of the gasket molds 3, and is generally an integer multiple of the height of the gasket molds 3. Several upper mold plates 1 have mounting holes 11 arranged horizontally and longitudinally at intervals on both sides and in the middle, so that each upper mold plate 1 passes through the mounting holes 11 sequentially through several threaded guide posts 21 provided on the lower mold plate 2, and is then stacked on the lower mold plate 2. Corresponding Torx nuts 4 are then screwed onto each threaded guide post 21 to ensure that each Torx nut... Nut 4 flattens and fixes several upper mold plates 1 onto the lower mold plate 2. Different shaped washer molds 3 are engaged with positioning pins 23 on the groove 22 of the lower mold plate through positioning holes at the bottom, thus positioning the washer molds 3 within the groove 22. The round holes 12 on the stacked upper mold plates 1 and the groove 22 of the lower mold plate 2 form an upward-opening groove. The operator fills the groove with silicone liquid, allowing it to solidify at room temperature. After solidification, the pendulum nut 4 is rotated in the reverse direction to detach from the threaded guide post 21, allowing the stacked upper mold plates 1 to be removed from the threaded guide posts 21. This makes it easy to remove the product from the mold, reducing product damage. Furthermore, one mold can simultaneously produce multiple types of silicone gasket buttons, improving the mold's production efficiency for silicone button gaskets. Both the upper mold plate 1 and the lower mold plate 2 are made of acrylic sheets. These fasteners for shelf products can be manufactured with machining centers, ultrasonic welding instruments, etc., making the manufacturing process easy, with low barriers to entry and short production cycles, facilitating large-scale promotion and use.

[0022] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
