Description

A molding die for toy manufacturing Technical Field

[0001] This utility model relates to the technical field, and in particular to a molding die for toy processing. Background Technology

[0002] In the toy manufacturing industry, with the increasing market demand for toys and the rising quality requirements, the limitations of traditional toy molding dies have become increasingly apparent. They are inadequate in temperature control, and heating and cooling are difficult to coordinate. For example, single heating methods result in slow temperature rise and uneven temperature distribution, affecting toy molding time and quality. The cooling process partially relies on air cooling technology, which has limited cooling speed, is susceptible to environmental interference leaving airflow marks on the product surface, and is also energy-intensive and costly. Therefore, the development of toy molding dies that can simultaneously achieve heating and cooling cycles to improve production efficiency and product quality is urgently needed.

[0003] The publication document with application number CN217777538U describes a molding die for toy processing, including a support base. A lower mold body is bolted to the middle of the upper surface of the support base. Connecting frames are welded to both sides of the upper surface of the support base. Two cylinders are bolted to the top of the connecting frames. An upper mold body is bolted to the end of each cylinder inside the connecting frames. A fan is bolted to the inside of the support base. By designing a channel on the side of the lower mold body, air can be introduced into the channel through a connecting pipe and an inlet when the fan is running. When air is introduced through the inlet, air is blown into the channel, which facilitates the removal of internal heat and discharge to the outside through the outlet. This facilitates faster heat dissipation inside the lower mold body. When the lower mold body dissipates heat quickly, it is easier to process toys by using the lower and upper mold bodies, making it convenient for rapid processing and improving the toy processing speed.

[0004] Compared to the air-cooling method used in the aforementioned publicly available documents, this solution employs a liquid cooling circulation system, which offers significant advantages. Air cooling primarily relies on fans to remove heat, while liquid cooling circulation more effectively avoids many of the problems associated with air cooling. Liquid cooling circulation consumes less energy, and its cooling effect is comparatively better than air cooling. Furthermore, liquid cooling circulation prevents wind from affecting the processed products, such as preventing surface defects caused by wind.

[0005] To address this issue, we propose a technical solution for molding dies used in toy manufacturing. This solution involves heating the injection molding material using heating copper pipes and coils within the die's fixed components. The cooling system utilizes annular pipes mounted on the outer walls of the upper and lower die seats, along with strip-shaped distribution pipes, inlet ports, outlet ports, and flexible delivery hoses to achieve uniform cooling circulation. The delivery system employs a booster pump and a circulating pump within a storage tank, along with delivery and circulation pipes, to ensure continuous and stable coolant circulation. This solution solves the problem of simultaneous heating and cooling circulation, thereby improving production efficiency and product quality. Summary of the Invention

[0006] The purpose of this invention is to provide a molding die for toy processing, which solves the problem of facilitating simultaneous heating and cooling cycles, thereby improving production efficiency and quality.

[0007] To achieve the above objectives, this utility model provides a molding die for toy processing, including a fixed bracket and a fixing component. The fixing component is fixedly connected inside the fixed bracket, and the fixing component includes two hydraulic cylinders. The two hydraulic cylinders are fixedly connected to the upper surface of the inner wall of the fixed bracket, and an upper mold base is fixedly connected to the lower end of the two hydraulic cylinders. A lower mold base is fixedly connected to the lower surface of the inner wall of the fixed bracket. Circular grooves are formed inside the upper and lower mold bases, and multiple heating copper tubes are embedded in the inner walls of the circular grooves. Heating coils are fixedly installed inside the multiple heating copper tubes. Multiple strip-shaped holes are formed on the surface of the groove wall located in the middle of the multiple heating copper tubes inside the circular grooves. Cooling components are fixedly connected to the outer walls of the circular grooves inside the upper and lower mold bases.

[0008] The cooling assembly includes two sets of annular tubes, with multiple strip-shaped diverter tubes connected to the middle of the two sets of annular tubes. The two sets of annular tubes are respectively installed on the outer walls of the upper mold base and the lower mold base. The top of each set of annular tubes is fixedly connected to a liquid inlet, and the bottom of each set of annular tubes is connected to a liquid outlet. The top of the liquid inlet and the bottom of the liquid outlet are fixedly connected to two sets of infusion hoses.

[0009] By coordinating the arrangement of the annular pipe, strip-shaped diversion pipe, liquid inlet, liquid outlet, and liquid delivery hose, the coolant is made to flow and circulate evenly around the upper and lower mold seats, thereby achieving the purpose of rapid and uniform cooling of the injection molded product.

[0010] The fixed support is fixedly connected to the top of the infusion assembly, which includes a storage tank. A booster pump is fixedly installed inside the storage tank. A water delivery pipe is fixedly connected to the output end of the booster pump. A circulating water pump is fixedly connected to the end of the storage tank away from the water delivery pipe. A circulating water pipe is fixedly connected to one end of the circulating water pump.

[0011] By connecting the booster pump and the circulating pump in the liquid storage tank to the water supply pipe and the circulating water pipe respectively, the coolant is extracted, transported and circulated, so as to continuously provide coolant to the cooling components and ensure their recycling.

[0012] The circulating water pump is fixedly connected to a circulating connection pipe at the end away from the circulating water pipe. Both the water supply pipe and the circulating water pipe are L-shaped. One end of the infusion hose at the top away from the inlet is fixedly connected to the pipe wall surface of the water supply pipe, and the other end of the infusion hose at the top away from the outlet is fixedly connected to the pipe wall surface of the circulating water pipe.

[0013] By connecting the L-shaped water supply pipe, circulating water pipe, and liquid supply hose, a smooth circulation path is achieved for the coolant to flow from the storage tank into the cooling components through the water supply pipe, and then back from the cooling components to the storage tank through the circulating water pipe, thus ensuring the stable operation of the coolant circulation system.

[0014] The lower mold base has a feed inlet on one side, and a flow channel is provided on the upper surface of the lower mold base near the feed inlet. The end of the flow channel away from the feed inlet is located on one side of the upper surface of the circular groove inside the lower mold base.

[0015] By setting up the inlet and the flow channel, the injection molding material is smoothly introduced from the outside into the circular groove of the lower mold base, so as to guide the material to flow accurately into the designated molding area.

[0016] The fixed bracket has a controller fixedly connected to its surface, the controller has a control screen fixedly connected to its surface, a control button group is fixedly installed on one side of the control screen, and the controller has an installation structure related to controlling the molding die for processing the toy installed inside.

[0017] Through the coordination of the controller, control screen and control button group, the user can achieve precise control of various components of the molding die, such as hydraulic cylinders, heating copper pipes, booster water pumps, and circulating water pumps, so as to flexibly adjust the working status of the mold according to the toy processing requirements.

[0018] This utility model discloses a molding die for toy manufacturing. The upper and lower mold bases in the fixed assembly have circular grooves inside, with multiple heating copper tubes embedded in the inner walls of the grooves. Heating coils are installed inside the heating copper tubes. When heating is activated, current flows through the heating coils to generate heat, which is transferred to the heating copper tubes and then conducted to the circular grooves, thereby heating the injection molding material placed inside the circular grooves and providing the required temperature for toy injection molding.

[0019] The cooling assembly consists of two sets of annular tubes, respectively installed on the outer walls of the upper and lower mold bases. Multiple strip-shaped distribution tubes connect to the middle of each annular tube, with an inlet at the top and an outlet at the bottom. Both the inlet and outlet are connected to flexible delivery hoses. When cooling is required, coolant flows from the delivery hoses through the inlets into the annular tubes, is evenly distributed through the strip-shaped distribution tubes, and engages with the strip-shaped holes on the circular grooves to cool the injection-molded product. The coolant then flows out from the outlet through the delivery hoses. This structural design achieves effective circulation of the coolant around the mold, quickly removing heat from the product and achieving the cooling purpose.

[0020] The infusion assembly, located atop a fixed support, includes a storage tank containing a booster pump and a circulating pump. The booster pump's output is connected to a water delivery pipe, and the circulating pump is connected to a circulating water pipe. During operation, the booster pump draws coolant from the storage tank and delivers it through the water delivery pipe and infusion hose to the inlet of the cooling assembly. The cooled coolant then flows from the drain outlet through the infusion hose into the circulating water pipe, and is subsequently pumped back to the storage tank by the circulating pump, completing the coolant circulation and ensuring a continuous and stable cooling process.

[0021] In summary, the design of the heating effect inside the fixed component and the circulating cooling effect between the cooling component and the infusion component facilitates the simultaneous heating and cooling cycle of the molding die used in toy processing, effectively improving toy processing efficiency and product quality.

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings.

[0030] Please refer to Figures 1, 2, 3, and 5. A molding die for toy processing includes a fixed bracket 1 and a fixed component 2. The fixed component 2 is fixedly connected inside the fixed bracket 1. The fixed component 2 includes two hydraulic cylinders 201. Two hydraulic cylinders 201 are fixedly connected to the upper surface of the inner wall of the fixed bracket 1.

[0031] In this embodiment, the fixing component 2 achieves the technical effect of heating the injection molding material by embedding a heating copper tube 205 with a heating coil 206 into the inner wall of the circular groove 204 inside the upper and lower mold bases 203; the cooling component 3 achieves the technical effect of uniformly cooling the injection molded product by means of two sets of annular tubes 301 installed on the outer wall of the upper and lower mold bases 203, with a strip-shaped diversion tube 302 connected in the middle of the tube, and a liquid inlet 303 at the top and a liquid outlet 304 at the bottom connected to a liquid delivery hose 305; the liquid delivery component 4 relies on the booster water pump 402 and the circulating water pump 404 in the liquid storage tank 401 at the top of the fixing bracket 1, which are respectively connected to the water delivery pipe 403 and the circulating water pipe 405, to achieve the technical effect of circulating the coolant to the cooling component 3 and returning it, thus ensuring that the molding die for toy processing achieves the functions of heating and cooling circulation.

[0032] Please refer to Figures 1 and 4. The cooling assembly 3 includes two sets of annular pipes 301. Multiple strip-shaped diversion pipes 302 are connected to the middle of the two sets of annular pipes 301. The two annular pipes 301 are respectively installed on the outer wall of the upper mold base 202 and the lower mold groove. The top of each set of annular pipes 301 is fixedly connected to a liquid inlet 303, and the bottom of each set of annular pipes 301 is connected to a liquid outlet 304. The top of the liquid inlet 303 and the bottom of the liquid outlet 304 are fixedly connected to two sets of infusion hoses 305.

[0033] The top of the fixed bracket 1 is fixedly connected to the infusion assembly 4, which includes a storage tank 401. A booster pump 402 is fixedly installed inside the storage tank 401. A water delivery pipe 403 is fixedly connected to the output end of the booster pump 402. A circulating water pump 404 is fixedly connected to the end of the storage tank 401 away from the water delivery pipe 403. A circulating water pipe 405 is fixedly connected to one end of the circulating water pump 404.

[0034] The end of the circulating water pump 404 away from the circulating water pipe 405 is fixedly connected to the circulating connection pipe 406. Both the water supply pipe 403 and the circulating water pipe 405 are L-shaped. The end of the infusion hose 305 at the top away from the inlet 303 is fixedly connected to the pipe wall surface of the water supply pipe 403, and the end of the infusion hose 305 at the top away from the outlet 304 is fixedly connected to the pipe wall surface of the circulating water pipe 405.

[0035] A feed inlet 5 is provided on one side of the lower mold base 203. A flow channel 6 is provided on the upper surface of the lower mold base 203 near the feed inlet 5. The end of the flow channel 6 away from the feed inlet 5 is located on one side of the upper surface of the circular groove 204 inside the lower mold base 203.

[0036] A controller 7 is fixedly connected to the surface of the fixed bracket 1, a control screen 8 is fixedly connected to the surface of the controller 7, a control button group 9 is fixedly installed on one side of the control screen 8, and an installation structure related to controlling the molding die used for processing the toy is installed inside the controller 7.

[0037] In this embodiment, the cooling component 3 uses two sets of annular pipes 301 respectively installed on the outer walls of the upper and lower mold bases 203. Multiple strip-shaped distribution pipes 302 are connected to the middle of the annular pipes 301. The top end has an inlet 303, and the bottom end has an outlet 304, both connected to a flexible tubing 305. This structure enables uniform flow and circulation of coolant around the mold, achieving rapid and uniform cooling of the injection-molded product. The controller 7 is fixed to the surface of the fixed bracket 1, and its surface is connected to a control screen 8. A control button group 9 is located on one side, and the internal structure houses structures related to mold control. This allows the user to precisely control various mold components such as the hydraulic cylinder 201, heating copper pipe 205, and the coolant circulation of the cooling component 3, achieving the goal of flexibly adjusting the mold's working state according to toy processing requirements.

[0038] When using the molding die for toy processing, its working principle is as follows: First, the user needs to make preparations by adding coolant into the storage tank 401 and connecting the feed pipe to prepare for conveying raw materials. At the same time, the relevant toy injection mold is installed in the circular groove 204 inside the upper mold base 202 and the lower mold base 203.

[0039] Once ready, the user operates the vertically mounted hydraulic cylinder 201 via the controller 7. The hydraulic cylinder 201 lowers the upper mold base 202, bringing it into contact with the lower mold base 203. Subsequently, using the design of the external plastic tube, the feed port 5, and the drainage channel 6, the injection molding material is transported to the circular groove 204 inside the lower mold base 203.

[0040] After the raw material is delivered, the electric heating wire is activated to heat multiple heating copper tubes 205. The heat is conducted through the heating copper tubes 205 to the circular groove 204 to heat and inject the raw material.

[0041] After injection molding is completed, when cooling is required, the user again controls the booster water pump 402 via the controller 7. The booster water pump 402 draws coolant from the storage tank 401 and delivers it through the water pipe 403. The coolant enters the interior of the annular pipe 301 through the inlet 303 at the top of the annular pipe 301 on the upper mold base 202 and the lower mold base 203. Because the multiple strip-shaped diversion pipes 302 in the middle of the annular pipe 301 cooperate with the strip holes 207 opened inside the circular groove 204, the coolant can cool down the heated injection-molded product.

[0042] During the cooling process, the coolant after cooling the product is discharged into the circulating water pipe 405 by using the design of the bottom drain port 304 of the two sets of annular pipes 301 and the infusion hose 305, and then the coolant is recycled by the circulating water pump 404.

[0043] The above-disclosed embodiments are merely one type of molding die for toy processing or a variety of preferred embodiments of this application, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent changes made in accordance with the claims of this application, still fall within the scope of this application.
