Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically to a mold for preparing adhesive sheets. Background Technology

[0002] Adhesive sheets are a key material widely used in electronic packaging, automotive component bonding, aerospace composite material lamination, and new energy battery assembly. Their manufacturing process directly affects product performance and production efficiency. Uniform coating and shaping of the adhesive layer are typically achieved through mold forming. Molds for adhesive sheet preparation are mostly made of metals (such as stainless steel and aluminum alloys) or polymer materials (such as polyimide and epoxy resin).

[0003] As shown in the prior art published in CN216160262U, although this prior art first fills the product to be tested into the groove of the base plate, then closes the cover plate, and connects the base plate and the cover plate around the perimeter with insertion holes and bolts, and uses auxiliary grooves on the sides for secondary reinforcement, and then uses the buckles on the base plate to fold up and fasten the cover plate tightly, the tightness is strong, making it easy to form the product to be tested. The combination of PTFE plate and stainless steel plate is not easily deformed or damaged, ensuring that the prepared sample pieces are of consistent size, demolding does not require a release agent, and the sample sheet is cut after preparation, avoiding the test error caused by material shrinkage that exists when directly preparing samples according to the test size. However, after the preparation is completed, the temperature of the base plate is still relatively high, which will affect the cooling and forming efficiency of the adhesive sheet, and also make it inconvenient for the staff to handle the material. Utility Model Content

[0004] Therefore, this utility model provides an adhesive sheet preparation mold to solve the problem that the cooling and forming efficiency of adhesive sheets is low due to the high temperature of the base plate in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adhesive sheet preparation mold, comprising a mold component for preparing adhesive sheets;

[0006] The exterior of the mold component serves as a heat dissipation component for cooling the adhesive sheet;

[0007] The heat dissipation component includes multiple heat-conducting plates disposed at the bottom of the mold part, and the bottom of the multiple heat-conducting plates is interspersed with the same air duct, the cross-section of which is wavy.

[0008] Furthermore, the heat-conducting plate has an air hole on its outer top surface, and the air hole is located at the top of the air duct.

[0009] Furthermore, the air duct is provided with fixing plates for connecting mold parts on both the front and rear sides, and the front and rear ends of the heat conduction plate are respectively fixed to the side of the two fixing plates that are close to each other.

[0010] The bottom of the fixing plate has multiple spaced fixing holes, and the bottom of the fixing holes is provided with fixing bolts. The top of the fixing bolts passes through the fixing holes and extends into the mold part. The fixing bolts are threadedly connected to the mold part.

[0011] Furthermore, both ends of the duct are threaded with mounting rings, and a filter screen is installed inside the mounting ring near the end of the duct.

[0012] Furthermore, the mold component includes a top mold base disposed on the top of the bottom mold base, the top of the bottom mold base having a material groove for preparing adhesive sheets, and a through hole being provided on one side of the bottom of the bottom mold base corresponding to the material groove;

[0013] The heat-conducting plate, air duct, and fixing plate are all installed inside the through hole, and the fixing plate is fixed to the bottom mold base by fixing bolts. The top of the heat-conducting plate is in contact with the bottom of the bottom mold base.

[0014] Furthermore, each of the four corners of the bottom of the top mold base is provided with a positioning post, and a positioning groove is opened on the top of the bottom mold base corresponding to the positioning post, with the bottom end of the positioning post extending into the positioning groove.

[0015] Furthermore, slots are provided on both sides of the bottom mold base, and a card plate for connecting the top mold base is provided inside the slot.

[0016] Furthermore, the clamping plate is provided with two spaced fastening bolts on the side away from the bottom mold base. The fastening bolts penetrate the clamping plate and extend into the bottom mold base, and are threadedly connected to the bottom mold base.

[0017] This utility model has the following advantages:

[0018] 1. The air duct is connected to the air supply equipment at one end, which allows the gas to circulate inside the duct. The corrugated shape of the duct extends the gas flow path, allowing the gas to fully absorb the heat from the heat-conducting plate, thereby improving the heat dissipation efficiency of the heat-conducting plate. At the same time, it also improves the heat dissipation effect of the heat-conducting plate on the bottom mold base, allowing the adhesive sheet on the bottom mold base to cool and solidify quickly, improving the molding efficiency, and also avoiding the situation where the material is difficult to remove due to excessive temperature and adhesion.

[0019] 2. By removing the fixing bolts, the fixing plate can be separated from the bottom mold base, which makes it easy to remove the heat conduction plate and air duct for inspection and maintenance, thus achieving the effect of convenient disassembly and assembly of the heat conduction plate and air duct for maintenance;

[0020] 3. The filter screen filters impurities in the gas, preventing them from adhering to the inside of the duct and causing pollution. At the same time, the rotating installation ring allows for easy removal of the filter screen for cleaning and maintenance. Attached Figure Description

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Refer to the instruction manual appendix Figure 1-5This utility model provides a mold for preparing adhesive sheets, including a mold component for preparing adhesive sheets; the mold component includes a top mold base 10 disposed on the top of a bottom mold base 9, a material groove 11 for preparing adhesive sheets is opened on the top of the bottom mold base 9, and a through hole 12 is opened on the bottom of the bottom mold base 9 corresponding to the material groove 11; a heat-conducting plate 1, an air duct 2 and a fixing plate 4 are all installed inside the through hole 12, and the fixing plate 4 is fixed together with the bottom mold base 9 by fixing bolts 6, and the top of the heat-conducting plate 1 is in contact with the bottom of the bottom mold base 9.

[0031] Workers place the material for preparing adhesive sheets into the material tank 11, and then place the top mold base 10 on top of the bottom mold base 9. The top mold base 10 has positioning posts 13 at each of its four bottom corners, and the bottom mold base 9 has a positioning groove 14 on one side of the top corresponding to the positioning posts 13. The bottom end of the positioning post 13 extends into the positioning groove 14. The bottom mold base 9 has slots 15 on both sides, and the slots 15 have a retaining plate 16 for connecting the top mold base 10. This allows the top mold base 10 to be precisely fitted with the bottom mold base 9 by the engagement of the positioning posts 13 with the positioning grooves 14, the retaining plate 16, and the slots 15, thus preventing misalignment between the top mold base 10 and the bottom mold base 9.

[0032] Furthermore, the clamping plate 16 has two spaced fastening bolts 17 on the side away from the bottom mold base 9. The fastening bolts 17 pass through the clamping plate 16 and extend into the bottom mold base 9. The fastening bolts 17 are threadedly connected to the bottom mold base 9, allowing the operator to fix the clamping plate 16 to the bottom mold base 9 using the fastening bolts 17. This enhances the tightness of the connection between the clamping plate 16 and the bottom mold base 9. At the same time, it also ensures the stability of the connection between the top mold base 10 and the bottom mold base 9, preventing the top mold base 10 from shaking or loosening. After the top mold base 10 and the bottom mold base 9 are attached and fixed, the operator places the mold part as a whole inside the oven for heating and preparation.

[0033] After preparing the adhesive sheet using the above-mentioned mold components, the mold components need to be cooled down, such as... Figure 1-5 As shown, the heat dissipation component is used to cool the adhesive sheet on the outside of the mold part; the heat dissipation component includes multiple heat-conducting plates 1 located at the bottom of the mold part, and the bottom of the multiple heat-conducting plates 1 is connected to the same air duct 2. The cross-section of the air duct 2 is wavy, and the top of the heat-conducting plate 1 is provided with an air hole 3, which is located at the top of the air duct 2.

[0034] After removing the mold parts, the operator connects one end of the air duct 2 to the air supply equipment, allowing gas to circulate inside the air duct 2. Because the air duct 2 is corrugated, the gas flow path is extended, allowing the gas inside the air duct 2 to fully absorb the heat from the heat-conducting plate 1, thereby improving the heat dissipation efficiency of the heat-conducting plate 1. At the same time, it also improves the heat dissipation effect of the heat-conducting plate 1 on the bottom mold base 9, allowing the adhesive sheet on the bottom mold base 9 to cool and solidify quickly, improving the molding efficiency. It also makes it easier for the operator to remove the material, avoiding the situation where the adhesive sheet sticks to the bottom mold base 9 due to excessive temperature.

[0035] To ensure the performance of the heat-conducting plate 1 and the air duct 2, they need to be easily removable for inspection and maintenance. Figure 3 and 4 As shown, the front and rear sides of the air duct 2 are provided with fixing plates 4 for connecting the mold parts, and the front and rear ends of the heat conduction plate 1 are respectively fixed to the side of the two fixing plates 4 that are close to each other; the bottom of the fixing plate 4 is provided with multiple spaced fixing holes 5, and the bottom of the fixing holes 5 is provided with fixing bolts 6. The top of the fixing bolts 6 passes through the fixing holes 5 and extends into the mold parts, and the fixing bolts 6 are threadedly connected to the mold parts.

[0036] When removing the heat-conducting plate 1 and the air duct 2, since the heat-conducting plate 1 is connected to two fixing plates 4, and the fixing plates 4 are fixed to the bottom mold base 9 by fixing bolts 6, the heat-conducting plate 1 and the air duct 2 can be removed without being restricted in position for inspection and maintenance after the fixing bolts 6 are removed. At the same time, the heat-conducting plate 1 can also be fixed to the bottom mold base 9 by the connection between the fixing bolts 6 and the bottom mold base 9, so as to achieve the effect of convenient disassembly and assembly of the heat-conducting plate 1 and the air duct 2.

[0037] To ensure the effective absorption of heat from the heat-conducting plate 1 by the air duct 2, the air inside the air supply equipment needs to be filtered to prevent impurities in the air from adhering to and contaminating the air duct 2. Figure 5 As shown, both ends of the air duct 2 are threaded with mounting rings 7, and a filter screen 8 is installed inside the end of the mounting ring 7 closest to the air duct 2. The threaded connection between the mounting ring 7 and the air duct 2 makes it easy for workers to install the filter screen 8 into the air duct 2. This allows the filter screen 8 to filter impurities in the gas, preventing impurities from adhering to the inside of the air duct 2 and causing pollution. At the same time, the mounting ring 7 can be rotated and disassembled, making it easy to remove the filter screen 8 for cleaning and maintenance, ensuring the performance of the filter screen 8.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
