Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic mold technology, specifically a plastic mold with rapid cooling function. Background Technology
[0002] Plastic mold is a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. Through the coordinated changes of the mold's punch and die and auxiliary molding system, a series of plastic parts of different shapes and sizes can be processed. Molten plastic is injected under high pressure into a closed metal mold cavity, and after cooling and solidification, the mold is opened to remove the product.
[0003] Excessive mold temperature can prevent subsequent batches of molten plastic from solidifying quickly, causing production disruptions. Cooling systems can maintain a stable low temperature in the mold, ensuring continuous operation of the production line. Therefore, plastic molds need cooling functions. However, currently, plastic molds with cooling functions often use water as a single medium for cooling, which cannot be adapted to high and low temperature stages. At the same time, the flow rate of the liquid cannot be controlled, resulting in unnecessary waste.
[0004] In view of this, we propose a plastic mold with rapid cooling function. Utility Model Content
[0005] The purpose of this invention is to provide a plastic mold with a rapid cooling function to solve the problems mentioned in the background art.

[0015] In a further embodiment, the scraper is provided in multiple sets.
[0016] In a further embodiment, the scraper is made of an elastic material, and the scraper's movement trajectory intersects with the filter box, thereby cleaning the filter box more effectively.
[0017] Compared with the prior art, this utility model provides a plastic mold with rapid cooling function, which has the following beneficial effects:
[0018] 1. This plastic mold with rapid cooling function is designed to quickly cool down the mold after molding and control the water flow. It is equipped with a cooling component, along with a liquid storage tank, a first electric pump, a top cover, a delivery pipe, a valve, a drain pipe, a water tank, a second electric pump, and a filter plate. During the high-temperature stage, water is used to quickly remove heat from the mold, which is suitable for the strong heat dissipation requirements in high-temperature environments.

The flow rate is controlled by the valve, making the cooling more precise.
[0019] 2. This plastic mold with rapid cooling function is equipped with a filter assembly to clean and filter the water in the water tank. When the second electric pump draws water, the water passes through the filter box, and impurities in the water are intercepted in the filter box. The servo motor, rotating shaft and scraper clean the impurities attached to the filter box. The filter box is then replaced periodically from the sealed port, thereby improving the water quality in the water tank and increasing the cooling efficiency. Attached Figure Description

[0031] Please see Figures 1-5 This utility model provides a technical solution:
[0032] A plastic mold with rapid cooling function includes a base 1, a fixed mold 2 fixedly installed at the top center of the base 1, and a movable mold 3 provided on the fixed mold 2.
[0033] In one embodiment of this utility model, a cooling component 4 is provided on the base 1. The cooling component 4 includes a liquid storage tank 41. The liquid storage tank 41 is fixedly installed at one end of the top of the base 1. One end of a first electric pump 42 is fixedly installed at one end of the liquid storage tank 41. The other end of the first electric pump 42 is fixedly connected to a liquid storage device. A top cover 43 is fixedly installed on the top of the liquid storage tank 41. One end of a delivery pipe 44 is fixedly installed at the other end of the liquid storage tank 41. A valve 45 is provided on the delivery pipe 44. The other end of the delivery pipe 44 is fixed... The fixed mold 2 is connected, and a drain pipe 46 is fixedly installed on the outside of the fixed mold 2. A water tank 47 is fixedly installed on the other end of the top of the base 1. A second electric pump 48 is fixedly installed on one end of the water tank 47. The other end of the water tank 47 is fixedly connected to the delivery pipe 44. The other end of the second electric pump 48 is fixedly connected to the water storage device. A filter plate 49 is fixedly installed on one end of the delivery pipe 44. Multiple sets of delivery pipe 44 and valve 45 are provided. The internal spaces of the liquid storage tank 41, delivery pipe 44, drain pipe 46 and water tank 47 are all connected.
[0034] In this embodiment, a liquid storage tank 41 and a water tank 47 store coolant and water, respectively. A first electric pump 42 is installed at one end of the liquid storage tank 41, which replenishes coolant from the liquid storage device. The water tank 47 is pumped by a water storage device connected to a second electric pump 48. When the plastic mold is at a high temperature, such as immediately after injection molding, rapid heat dissipation is required. The water in the water tank 47 is pumped out by the second electric pump 48 and transported to the interior of the fixed mold 2 through the delivery pipe 44. The water circulates within the fixed mold 2, utilizing its high thermal conductivity to quickly remove heat from the mold, achieving efficient heat dissipation. During this process, the valve 45 on the delivery pipe 44 can be opened or adjusted as needed to control the water flow and achieve precise cooling. It is worth noting that during the water delivery process in the water tank 47... The valve 45 on the pipe 44 at one end of the liquid storage tank 41 needs to be kept closed to prevent the two from being mixed, and vice versa. When the mold temperature drops to a low temperature stage, such as close to the ambient temperature or when it is necessary to prevent freezing, the first electric pump 42 starts and pumps the coolant in the liquid storage device into the fixed mold 2 through the pipe 44. Due to its low freezing point and stable temperature control characteristics, the coolant can circulate continuously in a low temperature environment to prevent the mold water circuit from freezing and maintain the mold temperature. Similarly, the valve 45 can adjust the coolant flow rate as needed. After the water or coolant completes the heat exchange in the fixed mold 2, it is discharged through the drain pipe 46. At the same time, the filter plate 49 on the pipe 44 filters the water and coolant. The filter plate 49 is then manually cleaned by the operator. The cooling component 4 realizes flexible switching and flow control of water and coolant to achieve a mixed cooling effect, accurately match the temperature requirements of the plastic mold at different stages, and effectively improve the mold cooling efficiency and product production quality.
[0035] In one embodiment of this utility model, a cleaning component 5 is provided on the water tank 47. The cleaning component 5 includes a sealing port 51. The sealing port 51 is opened on the top of the water tank 47. A servo motor 52 is fixedly installed on the top of the water tank 47. A fixing plate 53 is fixedly installed inside the water tank 47. A filter box 54 is placed inside the fixing plate 53. A rotating shaft 55 is rotatably installed inside the water tank 47 through a bearing component. The output end of the servo motor 52 is fixedly connected to the rotating shaft 55. A scraper 56 is fixedly installed on the outside of the rotating shaft 55. Multiple sets of scrapers 56 are provided. The scrapers 56 are made of elastic material, and the movement trajectory of the scrapers 56 intersects with the filter box 54.
[0036] In this embodiment, the sealing port 51 facilitates the disassembly and maintenance of the filter box 54. When the second electric pump 48 draws water from the water storage device to the water tank 47 for mold cooling, the water in the water storage device flows through the filter box 54. During this process, the filter box 54 performs a first-stage interception and filtration of impurities in the water to ensure the cleanliness of the water entering the mold cooling system and prevent impurities from clogging the delivery pipe 44 and affecting the cooling effect. After the servo motor 52 is started, it drives the rotating shaft 55 to rotate, which in turn causes the scraper 56 to rotate around the rotating shaft 55. During the rotation, the scraper 56 will stick tightly to the surface of the filter box 54 to remove impurities adhering to the filter box 54. Impurities on plate 4 are scraped off to prevent excessive accumulation of impurities in filter box 54 from affecting the filtration effect, maintaining the permeability of filter box 54 and maintaining filtration performance. After a period of use, a lot of impurities will accumulate in filter box 54. At this time, water tank 47 can be opened through the sealing port 51 at the top of water tank 47 to remove filter box 54 for cleaning or directly replace it with a new filter box 54. The water will then be filtered a second time through filter plate 49. When too many impurities accumulate in water tank 47, it needs to be cleaned manually by the operator. This will not be elaborated here, thereby improving the water quality and facilitating subsequent cooling work.
[0037] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the first electric pump 42, the second electric pump 48, and the servo motor 52. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
