Description

Technical Field

[0001] This utility model relates to the field of silicone mold technology, specifically to a silicone mold with metal positioning strips. Background Technology

[0002] Silicone molds are widely used in small-batch or handmade production due to their good flexibility and easy demolding, such as handicrafts, candles, resin ornaments, and prototype verification. However, in actual production, especially when the size of the silicone mold is large, there are still some problems with existing silicone molds that need to be solved.

[0003] When silicone molds are large, they are prone to deformation. This is because silicone material itself has a certain degree of elasticity and softness, and will gradually deform under its own weight over a long period of time. Additionally, during use, when materials for crafting handicrafts, candles, resin ornaments, or prototype verification are injected into the mold, the expansion force generated during the material's curing process will push the mold open, also causing deformation. Deformation can lead to displacement at the joint between the upper and lower molds, affecting the molding accuracy and quality of the handicrafts. This results in larger dimensional deviations in the produced handicrafts, or even defective products, ultimately reducing production efficiency and product qualification rates. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the purpose of this utility model is to provide a silicone mold with a metal positioning strip, which prevents the deformation of the upper silicone mold assembly and the lower silicone mold assembly by adding a fixing and positioning component, and prevents the two from shifting when they are combined.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A silicone mold with a metal positioning strip includes an upper silicone mold assembly, a lower silicone mold assembly, a fixing and positioning assembly, and an opening and closing limiting assembly. The upper silicone mold assembly and the lower silicone mold assembly are arranged vertically opposite each other. The opening and closing limiting assembly is detachably inserted into the outer edge of the upper silicone mold assembly and the lower silicone mold assembly, and presses and fixes the upper silicone mold assembly and the lower silicone mold assembly through it. The fixing and positioning assembly is respectively embedded in the interior of the upper silicone mold assembly and the lower silicone mold assembly.

[0007] As a further improvement to the above technical solution, the silicone lower mold assembly includes a lower mold main board and a shaped pressing block. The shaped pressing block is fixed to the top of the lower mold main board and forms an integral structure with it. The silicone upper mold assembly includes an upper mold main board and a shaped insert. The upper mold main board has a pressing groove for interlocking with the shaped pressing block. The shaped insert is fixed in the pressing groove of the upper mold main board and forms an integral structure with it. The opening and closing limiting component is detachably inserted into the outer edge of the upper mold main board and the lower mold main board. The fixing and positioning components are respectively embedded in the interior of the upper mold main board and the lower mold main board.

[0008] As a further improvement to the above technical solution, the fixing and positioning component includes a first positioning strip, a second positioning strip, a third positioning strip, and a fourth positioning strip. The first and second positioning strips are embedded in the upper mold main board at intervals, and the third and fourth positioning strips are embedded in the lower mold main board at intervals.

[0009] As a further improvement to the above technical solution, the irregularly shaped pressing block includes a first irregularly shaped pressing block, a second irregularly shaped pressing block and a third irregularly shaped pressing block, wherein the third irregularly shaped pressing block has a slot in the middle that mates with the irregularly shaped insert.

[0010] As a further improvement to the above technical solution, the opening and closing limiting component includes several limiting and fixing parts, each of which is a U-shaped structure formed by combining a vertical plate and two horizontal plates, and several limiting strips are respectively provided at intervals on the inner side of the two horizontal plates.

[0011] As a further improvement to the above technical solution, several limiting and fixing grooves are provided around the upper mold main board and the lower mold main board at intervals, and several limiting channels are respectively provided on the inner side of the several limiting and fixing grooves of the upper mold main board and the lower mold main board.

[0012] As a further improvement to the above technical solution, the first positioning strip, the second positioning strip, the third positioning strip and the fourth positioning strip are all made of metal rectangular frames.

[0013] The beneficial effects of this utility model are as follows:

[0014] By incorporating positioning strips made of metal into the interior of the upper and lower silicone mold assemblies, the internal stability of both is enhanced. When the silicone mold is large, the high rigidity of the metal positioning strips can offset the deformation of the silicone caused by its own weight or external pressure, disperse the internal pressure generated during the injection process, reduce the deformation or damage of the silicone mold caused by local stress concentration, and maintain the overall structural stability of the mold. At the same time, it can prevent the upper and lower silicone mold assemblies from shifting when they are combined, ensuring that the upper and lower molds are fully aligned when closed, and avoiding misalignment problems caused by silicone deformation.

Detailed Implementation

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5As shown in the figure, this utility model embodiment provides a silicone mold with a metal positioning strip, including a silicone upper mold assembly 1, a silicone lower mold assembly 2, a fixing and positioning assembly 3, and an opening and closing limiting assembly 4. The silicone upper mold assembly 1 and the silicone lower mold assembly 2 are arranged vertically opposite each other. The opening and closing limiting assembly 4 is detachably inserted into the outer edge of the silicone upper mold assembly 1 and the silicone lower mold assembly 2, and presses and fixes the silicone upper mold assembly 1 and the silicone lower mold assembly 2 through it. The fixing and positioning assembly 3 is respectively embedded in the inside of the silicone upper mold assembly 1 and the silicone lower mold assembly 2. The fixing and positioning assembly 3 prevents the silicone upper mold assembly 1 and the silicone lower mold assembly 2 from deforming and prevents them from shifting when they are combined. The opening and closing limiting assembly 4 cooperates to limit the opening and closing of the silicone upper mold assembly 1 and the silicone lower mold assembly 2, thereby improving the positioning accuracy and production quality of the silicone mold when opening and closing.

[0023] The silicone lower mold assembly 2 includes a lower mold main board 21 and a shaped pressing block. The shaped pressing block is fixed to the top of the lower mold main board 21 and forms an integral structure with it. The silicone upper mold assembly 1 includes an upper mold main board 11 and a shaped insert 12. The upper mold main board 11 has a pressing groove 13 for interlocking with the shaped pressing block. The shaped insert 12 is fixed in the pressing groove 13 of the upper mold main board 11 and forms an integral structure with it. The opening and closing limiting assembly 4 is detachably inserted into the outer edges of the upper mold main board 11 and the lower mold main board 21. The fixing and positioning assembly 3 is respectively embedded in the interior of the upper mold main board 11 and the lower mold main board 21.

[0024] The irregularly shaped pressing block includes a first irregularly shaped pressing block 22, a second irregularly shaped pressing block 23 and a third irregularly shaped pressing block 24, wherein the third irregularly shaped pressing block 24 has a slot 241 in the middle that cooperates with the irregularly shaped insert 12.

[0025] Reference Figure 2 The fixing and positioning component 3 includes a first positioning strip 31, a second positioning strip 32, a third positioning strip 33 and a fourth positioning strip 34. The first positioning strip 31 and the second positioning strip 32 are embedded in the upper mold main board 11 at intervals, and the third positioning strip 33 and the fourth positioning strip 34 are embedded in the lower mold main board 21 at intervals.

[0026] In the specific implementation of this utility model, the first positioning strip 31, the second positioning strip 32, the third positioning strip 33 and the fourth positioning strip 34 are all made of metal material to form rectangular frames. The high rigidity of the metal material can offset the deformation of the silicone caused by its own weight or external force. When making the silicone upper mold assembly 1 and the silicone lower mold assembly 2, each positioning strip is placed in the container for making the mold, so that it is embedded in its upper mold main board 11 and lower mold main board 21.

[0027] When the size of the silicone mold is large, the stability of the upper silicone mold assembly 1 and the lower silicone mold assembly 2 can be enhanced by positioning strips, which can disperse the internal pressure generated during the injection process, reduce the deformation or damage of the silicone mold caused by local stress concentration, and maintain the overall structural stability of the mold. At the same time, it can prevent the upper silicone mold assembly 1 and the lower silicone mold assembly 2 from shifting when they are combined, ensure that the upper and lower molds are fully aligned when they are closed, and avoid misalignment problems caused by silicone deformation.

[0028] Reference Figure 5 The opening and closing limiting component 4 includes several limiting and fixing parts 41. Each of the several limiting and fixing parts 41 is formed by combining a vertical plate 411 and two horizontal plates 412 to form a U-shaped structure. Several limiting strips 413 are respectively provided at intervals on the inner side of the two horizontal plates 412.

[0029] The upper mold main board 11 and the lower mold main board 21 are provided with a plurality of limiting and fixing grooves 5 spaced apart around their perimeters, and the limiting and fixing grooves 5 of the two are parallel and cooperate with the limiting and fixing member 41; the inner sides of the plurality of limiting and fixing grooves 5 of the upper mold main board 11 and the lower mold main board 21 are respectively provided with a plurality of limiting channels (not shown in the figure) that cooperate with the limiting strip 413.

[0030] When the upper silicone mold assembly 1 and the lower silicone mold assembly 2 are combined, the two horizontal plates 412 of the several limiting and fixing members 41 are respectively inserted into the several limiting and fixing grooves 5 of the upper mold main board 11 and the lower mold main board 21; the limiting strips 413 of the horizontal plates 412 are stuck in the limiting channels of the limiting and fixing grooves 5, thereby strengthening the limiting and fixing members 41 to limit and stabilize the upper silicone mold assembly 1 and the lower silicone mold assembly 2, and preventing the limiting and fixing members 41 from detaching from the upper mold main board 11 and the lower mold main board 21.
