Description

Technical Field

[0001] This utility model relates to the field of silicone sheet processing technology, specifically to a silicone sheet processing mold that is easy to cool. Background Technology

[0002] Silicone sheet processing molds are molds specifically designed for manufacturing silicone products, typically used to produce silicone sheets, silicone gaskets, and other similar items. Cooling is a crucial step in the silicone sheet processing process. After the silicone material is heated to a certain temperature, it is usually molded and cured (curing process). During curing, the silicone becomes more tough and stable, but this process requires proper temperature control.

[0003] There are many types of existing silicone sheet processing mold cooling devices. For example, the silicone sheet processing mold disclosed in patent CN220429093U is an easy-to-cool silicone sheet processing mold. This utility model solves the problem that existing silicone sheet processing molds cannot isolate external factors from interference during the initial molding of silicone sheets inside the mold, and also cannot allow the silicone sheets to be cooled by the combined action of external air cooling and internal water cooling. However, after a long period of use, the temperature of the coolant used to cool the silicone sheet processing mold will rise. Without effective handling of the rising temperature of the coolant, the coolant will not be able to effectively cool the silicone sheet processing mold. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a silicone sheet processing mold that is easy to cool, which can effectively solve the problem that the temperature of the mold cannot be cooled down after the coolant is used.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a silicone sheet processing mold that facilitates cooling, comprising:

[0007] cooling pool;

[0008] A circulating liquid supply assembly includes a drain pipe connected to one side of a cooling pool, a fixed bucket fixedly installed inside the drain pipe, a first transmission rod rotatably installed inside the fixed bucket, a plurality of first fan plates fixedly installed in a circumferential array on the outer wall of the first transmission rod, a metal collar fixedly installed on the outer wall of the first transmission rod, and a speed detection element sleeved on the outer wall of the first transmission rod and on the outer wall of the metal collar.

[0009] A cooling and heat-reducing assembly includes a cooling tank disposed on one side of a cooling pool. A second transmission rod is rotatably mounted inside the cooling tank. Multiple second fan plates are fixedly mounted in a circumferential array at the upper position of the outer wall of the second transmission rod. Multiple third fan plates are fixedly mounted in a circumferential array at the lower position of the outer wall of the second transmission rod. A conical flow divider is fixedly mounted on the outer wall of the second transmission rod between the second fan plates and the third fan plates.

[0010] Preferably, a cross is fixedly installed inside the fixed barrel, and the interior of the cross is rotatably connected to the first transmission rod. Two fixed brackets are symmetrically installed on one side of the cross, and the fixed brackets are fixedly connected to a speed detection element. The speed detection element is electrically connected to the controller.

[0011] Preferably, the outer wall of the drain pipe is connected to a feed pipe, the inner wall of the feed pipe is fixedly installed with a solenoid valve, the solenoid valve is electrically connected to a controller, the upper end face of the feed pipe is connected to a storage tank, the upper end face of the storage tank is slidably installed with a sealing plate, and a first water pump is fixedly installed on the inner wall of the drain pipe between the fixed tank and the feed pipe.

[0012] Preferably, the upper end face of the cooling tank is connected to a top tank, and the top tank is connected to one end of the cooling tank. The upper end face of the conical diverter plate is provided with a plurality of diverter slots arranged in a circumferential array. A partition plate is fixedly installed on the outer wall of the second transmission rod between the conical diverter plate and the third fan plate. The partition plate is fixedly connected to the inner wall of the cooling tank. A plurality of annular partition plates are fixedly installed on the upper end face of the partition plate. An inclined plate is fixedly installed between each of the annular partition plates and on the upper end face of the partition plate. A liquid outlet groove is provided in the annular partition plate.

[0013] Preferably, the lower end face of the cooling tank is provided with multiple air inlets, the outer wall of the cooling tank is provided with multiple air outlets arranged in a circumferential array below the partition, the inner wall of the cooling tank is provided with a flow groove, the outer wall of the cooling tank is provided with an air outlet groove at the upper position, and the outer wall of the cooling tank is connected to a return pipe at the position corresponding to the liquid outlet groove, and a second water pump is fixedly installed in the return pipe.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. A dynamic circulating heat dissipation system is formed by setting up a linkage structure between the circulating liquid supply component and the cooling component. When the coolant circulates between the cooling pool and the cooling tank, the rotation of the second and third fan plates, combined with the centrifugal dispersion effect of the conical flow divider and the flow channel, allows the coolant to form a uniform liquid film layer in the cooling tank. At the same time, the air convection channels of the air inlet and outlet holes are used to achieve efficient heat exchange between the coolant and the air. The inclined flow guiding design of the annular baffle and the inclined plate further extends the residence time of the coolant, allowing the high-temperature coolant to cool down fully during the flow process, solving the problem of cooling efficiency reduction caused by continuous heating of the coolant in traditional technology.

[0016] 2. Through a collaborative monitoring mechanism of a metal collar and a speed detection element, changes in coolant viscosity are sensed in real time. When the coolant viscosity increases due to water evaporation, the speed detection element triggers the controller to automatically open the solenoid valve. The spare coolant in the storage tank is then injected into the circulation system through the supply pipe, achieving dynamic compensation of coolant concentration. This design not only maintains the constant heat conduction performance of the cooling system but also avoids the need for manual intervention and maintenance, significantly improving the continuity and stability of the mold cooling process and ensuring the consistency of silicone sheet vulcanization molding quality.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 5 A silicone sheet processing mold that facilitates cooling, comprising:

[0027] Cooling pool 1;

[0028] The circulating liquid supply assembly 2 includes a drain pipe 201 connected to one side of the cooling pool 1. A fixed bucket 202 is fixedly installed inside the drain pipe 201. A first transmission rod 207 is rotatably installed inside the fixed bucket 202. Multiple first fan plates 208 are fixedly installed in a circumferential array on the outer wall of the first transmission rod 207. A metal collar 206 is fixedly installed on the outer wall of the first transmission rod 207. A speed detection element 205 is sleeved on the outer wall of the first transmission rod 207 and on the outer wall of the metal collar 206.

Multiple second fan plates 305 are fixedly mounted in a circumferential array at the upper position of the outer wall of the second transmission rod 304. Multiple third fan plates 311 are fixedly mounted in a circumferential array at the lower position of the outer wall of the second transmission rod 304. A conical diverter plate 306 is fixedly mounted on the outer wall of the second transmission rod 304 and between the second fan plates 305 and the third fan plates 311.

[0030] Reference Figure 3 A cross 203 is fixedly installed inside the fixed barrel 202. The interior of the cross 203 is rotatably connected to the first transmission rod 207. Two fixed brackets 204 are symmetrically installed on one side of the cross 203. The fixed brackets 204 are fixedly connected to the speed detection element 205. The speed detection element 205 is electrically connected to the controller. The speed detection element 205 uses an existing Hall effect sensor. The Hall effect sensor uses magnetic field induction to detect the speed of a rotating object.

[0031] Reference Figures 2 to 3 The outer wall of the drain pipe 201 is connected to the feed pipe 210. The inner wall of the feed pipe 210 is fixedly installed with a solenoid valve, which is electrically connected to the controller. The upper end of the feed pipe 210 is connected to the storage tank 211, which is filled with water-based coolant. Water-based coolant is the most common coolant, mainly composed of water and additives. Water has good thermal conductivity and can quickly remove heat. Corrosion inhibitors are added to prevent corrosion of the mold. A sealing plate 212 is slidably installed on the upper end of the storage tank 211. The inner wall of the drain pipe 201 and the fixed tank 202 between the feed pipe 210 are fixedly installed with a first water pump 209.

They are commonly used in various applications such as liquid transportation, pressurization, and drainage. The water pump converts the potential energy and kinetic energy of water into the energy of the flowing water through mechanical energy to achieve the purpose of transportation or increasing water pressure.

[0032] Reference Figures 4 to 5The upper end face of the cooling tank 301 is connected to the top tank 302, and the top tank 302 is connected to one end of the cooling tank 301. Multiple diversion slots 307 are arranged in a circumferential array on the upper end face of the conical diversion plate 306.

The partition plate 303 is fixedly connected to the inner wall of the cooling tank 301. Multiple annular partition plates 308 are fixedly installed on the upper end face of the partition plate 303. Inclined... The cooling tank 301 has a liquid outlet groove 310 inside the shaped plate 309 and the annular partition 308. Multiple air inlets 314 are provided on the lower end face of the cooling tank 301. Multiple air outlets 315 are provided in a circumferential array on the outer wall of the cooling tank 301 below the partition 303. A flow groove 316 is provided on the inner wall of the cooling tank 301. An air outlet groove 317 is provided on the outer wall of the cooling tank 301 at the upper position. A return pipe 312 is connected to the outer wall of the cooling tank 301 at the position corresponding to the liquid outlet groove 310. A second water pump 313 is fixedly installed inside the return pipe 312.

[0033] The working principle of this utility model is as follows:

[0034] By placing the silicone mold inside the cooling pool 1, which contains a coolant, the silicone mold is cooled. As the mold is continuously cooled, the coolant temperature rises. Turning on the first water pump 209 continuously pumps the coolant from the cooling pool 1 into the top tank 302 through the drain pipe 201. Simultaneously, the coolant generates hydraulic pressure through the first water pump 209, impacting the second fan plate 305. This causes the second fan plate 305 to rotate the second transmission rod 304, the conical diverter plate 306, and the third fan plate 311. After impacting the second fan plate 305, the coolant falls onto the upper surface of the conical diverter plate 306. The rotating conical diverter plate 306 generates centrifugal force in the coolant, causing it to slide within the diversion groove 307 towards the cooling tank 301. The coolant drips and flows in a dispersed manner along the inner wall and falls between the annular baffles 308. It then flows outward through the inclined plate 309 at the outlet tank 310. The rotating third fan plate 311 draws in outside air through the air inlet 314 into the cooling tank 301. Some of the air flows outward through the air outlet 315, thus circulating the air and cooling the baffles 303 and the coolant flowing above them. The other part of the air flows in the flow channel 316 and flows outward through the air outlet 317, thereby cooling the inner and outer walls of the cooling tank 301. This allows the coolant flowing dispersedly inside the cooling tank 301 to be cooled as a whole. The coolant flowing outward from the outlet tank 310 can be returned to the cooling pool 1 for reuse by turning on the second water pump 313 and flowing in the return pipe 312.

[0035] As the coolant flows through the drain pipe 201, it drives the first fan plate 208 to rotate. The rotating first fan plate 208 drives the first transmission rod 207 and the metal collar 206 to rotate together. As the coolant continuously cools the silicone mold, the water content decreases, and the viscosity of the coolant increases. This reduces the rotation amplitude of the first fan plate 208, the first transmission rod 207, and the metal collar 206. The rotational speed detection element 205 detects the rotation amplitude of the metal collar 206. When the electrical signal generated by the rotation amplitude is lower than the preset rotation amplitude, the controller controls the voltage input to the solenoid valve, causing the valve core of the solenoid valve to open accordingly. The spare coolant inside the storage tank 211 flows into the drain pipe 201 and mixes with the increased viscosity coolant, further increasing the coolant viscosity to ensure that the cooling efficiency of the coolant can effectively cool the silicone mold.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
