Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a high-efficiency cooling mold. Background Technology

[0002] In the field of injection molding, thin-wall injection molding is widely used in industries such as electronics, medical, and automotive due to its advantages such as achieving product lightweighting and shortening molding cycles. The definition of thin-walled molding is not only related to the product wall thickness but also involves factors such as the flow / wall thickness ratio, plastic viscosity, and heat transfer coefficient. Among these, the flow / wall thickness ratio is a key indicator, which is the ratio of the flow length L from the main runner of the mold to the farthest point of the finished product to the finished product wall thickness t. When L / t > 150, it is generally considered thin-walled injection molding. Existing thin-walled injection mold cooling systems, to simplify the processing, mostly adopt a straight-through water channel design perpendicular or parallel to the mold exterior. The cooling of the injection molded product is achieved by the circulating flow of water within the water channel carrying away heat from the mold.

[0003] However, existing cooling systems for thin-walled injection molds have significant drawbacks. Firstly, the fixed paths of the straight-through water channels make it difficult to conform to the complex contours of thin-walled products, resulting in insufficient cooling in some areas and over-cooling in others, leading to uneven cooling. This problem is particularly pronounced in thin-walled products with a large flow / wall thickness ratio, easily causing defects such as warping, shrinkage marks, and internal stress cracking, severely impacting product yield. Secondly, different injection molding materials have significantly different cooling requirements. Crystalline plastics require avoiding uneven crystallization, amorphous plastics require preventing internal stress cracking, heat-sensitive plastics require preventing localized overheating, and precision parts are extremely sensitive to dimensional deviations. However, straight-through water channels cannot flexibly adjust cooling parameters according to the thermophysical properties of different materials. The negative impacts of factors such as water channel length and flow rate on cooling are difficult to control within a reasonable range, further exacerbating the problem of uneven cooling and resulting in low mold usability.

[0004] Therefore, in response to the problems of uneven cooling, inability to adapt to the cooling requirements of different materials, and low product qualification rate of existing thin-walled injection mold cooling systems, there is an urgent need for a high-efficiency cooling mold that can achieve efficient and uniform cooling and flexibly adjust cooling parameters according to the characteristics of different injection molding materials, so as to meet the high-quality production requirements of thin-walled injection molded products. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency cooling mold to solve the problems existing in the prior art mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling mold, comprising:

[0007] The upper fixing plate has four sets of guide columns fixedly connected in a regular matrix at its bottom. The upper fixing plate has a vertically penetrating injection port, and the bottom of the upper fixing plate is integrally connected with a shaped protrusion.

[0008] A lower fixing plate is located directly below the upper fixing plate. Spare plates are fixedly connected to both sides of the top of the lower fixing plate, and a lower ejector plate is connected to the top of the lower fixing plate. An upper ejector plate is connected to the top of the lower ejector plate, and several sets of ejector pins are installed on the upper ejector plate.

[0009] A mold platform is fixedly connected to the top of the two sets of partition plates. A forming cavity is opened in the top of the mold platform, and four sets of guide grooves are opened in a regular matrix in the top of the mold platform. The guide pillars are movably connected in the guide grooves, and several sets of ejector pins are movably inserted in the mold platform.

[0010] Both the upper fixed plate and the mold table are equipped with cooling mechanisms. The cooling mechanisms include a first longitudinal flow channel, a second longitudinal flow channel, a third longitudinal flow channel, and a cross flow channel opened in the upper fixed plate and the mold table. The first longitudinal flow channel and the second longitudinal flow channel are respectively connected to both ends of the cross flow channel, and the third longitudinal flow channel is connected to the middle of the cross flow channel.

[0011] Preferably, the guide post and the guide groove are positioned vertically opposite each other, and the lower end of the guide post has a frustum-shaped structure.

[0012] Preferably, the cooling mechanism further includes:

[0013] An adjustable plug is connected to the inner wall of the third longitudinal flow channel via a threaded structure;

[0014] The handle is fixedly connected to one end of the adjustable plug;

[0015] The length of the adjustable plug is greater than the length of the third longitudinal channel.

[0016] Preferably, the adjustable plug has a first row of holes at the end away from the handle, and the adjustable plug has a second row of holes on its side, with the first row of holes communicating with the second row of holes;

[0017] Specifically, the adjustable plug is rotated to position the second row of holes inside the third longitudinal flow channel, thereby sealing the rear outlet of the third longitudinal flow channel; or

[0018] Rotate the adjustable plug so that the second row of holes is located outside the third longitudinal channel, so that the third longitudinal channel can drain liquid.

[0019] Preferably, the cooling mechanism further includes a temperature sensor, the probe of which is disposed at the junction of the second longitudinal channel and the transverse channel.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1) This application adopts a design in which the first longitudinal channel, the second longitudinal channel, the third longitudinal channel and the cross channel are interconnected to form a multi-path cooling water network. This network can better fit the complex contours of thin-walled products and effectively cover all areas of the product. Compared with the traditional straight water channel, this design shortens the length of a single water channel. At the same time, the cooperation of multiple channels achieves a similar effect to parallel branching, which can control the temperature difference between the inlet and outlet of the water channel within a low range and avoid over- or under-cooling in local areas. This allows injection molded products of different materials to maintain a relatively uniform temperature field during the cooling process, reducing problems such as uneven crystallization of crystalline plastics, internal stress cracking of non-crystalline plastics, and local overheating of heat-sensitive plastics. This significantly reduces the product defect rate and improves the product qualification rate.

[0022] 2) Due to the differences in thermophysical properties and cooling requirements of different injection molding materials (such as crystalline plastics, non-crystalline plastics, heat-sensitive plastics, etc.), this mold, through the setting of an adjustable plug, can flexibly adjust the on / off state and flow rate of the third longitudinal flow channel. When processing products of different materials, the position of the adjustable plug can be changed by rotating the handle, so that the second row of holes is located inside or outside the third longitudinal flow channel, thereby controlling the drainage of the third longitudinal flow channel, and thus adjusting the overall flow rate and flow distribution of the cooling water circuit. Combined with the real-time monitoring of the temperature at the junction of the second longitudinal flow channel and the cross flow channel by the temperature sensor, the operating status of the cooling system can be grasped in a timely manner, which is convenient for dynamically adjusting the cooling parameters according to the cooling requirements of different materials, so that the mold can adapt to the cooling requirements of various injection molding materials, enhancing the versatility and applicability of the mold.

[0023] 3) The multi-channel design of this application not only ensures the uniformity of cooling, but also reduces the resistance loss of water flow in the water channel by optimizing the water channel layout and flow channel structure, so that the water flow can maintain a high flow velocity and be in a turbulent state, thereby improving the heat exchange efficiency. At the same time, the shorter single water channel length and reasonable flow channel distribution accelerate the heat exchange speed between the mold and the water flow, which can quickly remove the heat generated during the injection molding process, shorten the cooling time of the product, thereby shortening the overall molding cycle, improving production efficiency, and providing strong support for large-scale industrial production.

[0024] 4) The cooling mechanism of the mold in this application is integrated with the overall structural design. The opening positions of each flow channel avoid the key stress components of the mold, so as not to affect the overall strength and stability of the mold. The adjustable plug adopts a threaded structure connection, which is convenient for installation, disassembly and maintenance. When the water channel is blocked or needs to be cleaned, the plug can be easily removed by turning the handle. The setting of the temperature sensor provides a basis for the intelligent control of the cooling system, which makes it easy for operators to monitor the cooling status in real time and make corresponding adjustments, reducing the difficulty of operation and improving the practicality and maintenance convenience of the mold.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] Please see Figures 1-9 This utility model provides a technical solution: a high-efficiency cooling mold, comprising:

[0045] The upper fixing plate 1 has four sets of guide columns 3 fixedly connected in a regular matrix at the bottom. The upper fixing plate 1 has a vertically penetrating injection port 6, and the bottom of the upper fixing plate 1 is integrally connected with a forming protrusion 9.

[0046] The lower fixing plate 2 is located directly below the upper fixing plate 2. The top two sides of the lower fixing plate 2 are fixedly connected to the partition plate 4, and the top of the lower fixing plate 2 is connected to the lower ejector plate 5. The top of the lower ejector plate 5 is connected to the upper ejector plate 7, and several sets of ejector pins 8 are installed on the upper ejector plate 7.

[0047] The mold platform 10 is fixedly connected to the top of the two sets of partition plates 4. A molding cavity 11 is opened in the top of the mold platform 10, and four sets of guide grooves 21 are opened in a regular matrix in the top of the mold platform 10. The guide post 3 is movably connected in the guide groove 21, and several sets of ejector pins 8 are movably inserted in the mold platform 10.

[0048] Cooling mechanisms are provided in both the upper fixed plate 1 and the mold table 10. The cooling mechanisms include a first longitudinal flow channel 11, a second longitudinal flow channel 12, a third longitudinal flow channel 13 and a cross flow channel 14 opened in the upper fixed plate 1 and the mold table 10. The first longitudinal flow channel 11 and the second longitudinal flow channel 12 are respectively connected to the two ends of the cross flow channel 14, and the third longitudinal flow channel 13 is connected to the middle of the cross flow channel 14.

[0049] Specifically, the cooling mechanism inside the upper fixed plate 1 includes: the first longitudinal channel 11 and the second longitudinal channel 12, which are connected to the front exterior of the upper fixed plate 1, and the third longitudinal channel 13, which is connected to the rear exterior of the upper fixed plate 1.

[0050] Specifically, the cooling mechanism inside the mold platform 10 includes: the first longitudinal channel 11 and the second longitudinal channel 12, which are connected to the front exterior of the mold platform 10, and the third longitudinal channel 13, which is connected to the rear exterior of the mold platform 10.

[0051] Specifically, the multi-channel design of this application (first longitudinal channel 11, second longitudinal channel 22, third longitudinal channel 13 and cross channel 14) not only ensures the uniformity of cooling, but also reduces the resistance loss of water flow in the water channel by optimizing the water channel layout and flow channel structure, so that the water flow can maintain a high flow velocity and be in a turbulent state, thereby improving the heat exchange efficiency. At the same time, the shorter single water channel length and reasonable flow channel distribution accelerate the heat exchange speed between the mold and the water flow, which can quickly remove the heat generated during the injection molding process, shorten the cooling time of the product, thereby shortening the overall molding cycle, improving production efficiency, and providing strong support for large-scale industrial production.

[0052] Specifically, the mating structure of the upper fixed plate 1, the lower fixed plate 2 and the mold table 10, combined with the cooling mechanism consisting of the first longitudinal flow channel 11, the second longitudinal flow channel 22, the third longitudinal flow channel 13 and the transverse flow channel 14, forms a multi-path cooling network, shortens the length of a single water channel, and can better fit the contour of the thin-walled product of the molding protrusion 9 and the molding cavity 20, reducing cooling dead angles; the precise fit of the guide pillar 3 and the guide groove 21 ensures the coaxiality of the mold closing, avoids the fitting deviation of the cooling water channel, and the ejector pin 8, the lower ejector plate 5 and the upper ejector plate 7 work together to achieve stable product ejection, thereby improving the overall cooling uniformity and molding stability, and reducing the defect rate of products of different materials.

[0053] Specifically, this application adopts a design in which the first longitudinal channel 11, the second longitudinal channel 22, the third longitudinal channel 13, and the cross channel 14 are interconnected, forming a multi-path cooling water network. This network can better fit the complex contours of thin-walled products and effectively cover all areas of the product. Compared with traditional straight-through water channels, this design shortens the length of a single water channel. At the same time, the cooperation of multiple channels achieves a similar effect to parallel branching, which can control the temperature difference between the inlet and outlet of the water channel within a low range, avoiding over- or under-cooling in local areas. This allows injection molded products of different materials to maintain a relatively uniform temperature field during the cooling process, reducing problems such as uneven crystallization of crystalline plastics, internal stress cracking of non-crystalline plastics, and local overheating of heat-sensitive plastics. This significantly reduces the product defect rate and improves the product qualification rate.

[0054] Reference manual attached Figures 1-3 The guide post 3 and the guide groove 21 are positioned vertically and vertically respectively, and the lower end of the guide post 3 is a frustum-shaped structure. Specifically, the frustum-shaped structure at the lower end of the guide post 3 corresponds to the vertical position of the guide groove 21, which can reduce impact wear during mold closing, improve the fitting accuracy between the two, ensure the coaxiality of the upper fixed plate 1 and the mold table 10 when the mold is closed, avoid the cooling water channel fitting deviation due to misalignment, indirectly ensure cooling uniformity, and extend the service life of the mold.

[0055] The cooling system also includes:

[0056] The adjustable plug 15 is connected to the inner wall of the third longitudinal channel 13 via a threaded structure;

[0057] The handle 16 is fixedly connected to one end of the adjustable plug 15;

[0058] The length of the adjustable plug 15 is greater than the length of the third longitudinal channel 13.

[0059] Specifically, the adjustable plug 15 is threaded to the third longitudinal channel 13, and the handle 16 is easy to operate. Its length is greater than that of the third longitudinal channel 13, which can flexibly control the on / off state of the third longitudinal channel 13. By adjusting the position of the plug, the water flow distribution can be changed to adapt to the cooling intensity requirements of different materials such as crystalline and non-crystalline materials, thereby enhancing the adjustment flexibility of the cooling system.

[0060] Reference manual attached Figures 6-7 The adjustable plug 15 has a first row of holes 17 at the end away from the handle 16, and the adjustable plug 15 has a second row of holes 18 on the side, with the first row of holes 17 and the second row of holes 18 connected.

[0061] Specifically, the adjustable plug 15 is rotated to position the second row of holes 18 inside the third longitudinal flow channel 13, thereby blocking the rear outlet of the third longitudinal flow channel 13 with the adjustable plug 15; or

[0062] Rotate the adjustable plug 15 so that the second row of holes 18 is located outside the third longitudinal channel 13, so that the third longitudinal channel 13 can drain liquid.

[0063] Specifically, the first row of holes 17 of the adjustable plug 15 is connected to the second row of holes 18. When the plug is rotated so that the second row of holes 18 is inside the third longitudinal channel 13, the outlet can be blocked, and when it is outside, the liquid can be discharged, thus realizing the fine control of the flow rate of the third longitudinal channel 13.

[0064] Reference manual attached Figure 8 The sealing operation mode is as follows: When the third longitudinal flow channel 13 needs to be sealed, the adjustable plug 15 is rotated by the handle 16, so that the second row of holes 18 on the side of the adjustable plug 15 is completely inside the third longitudinal flow channel 13. At this time, the second row of holes 18 is blocked by the inner wall of the third longitudinal flow channel 13, and the passage formed by the first row of holes 17 and the second row of holes 18 cannot be connected to the outside. The rear outlet of the third longitudinal flow channel 13 is blocked by the solid part of the adjustable plug 15. During operation, the coolant enters from the first longitudinal flow channel 11 and flows along the cross flow channel 14 to the second longitudinal flow channel 12. Since the third longitudinal flow channel 13 is blocked, the coolant cannot be discharged through the third longitudinal flow channel 13 and can only flow into the second longitudinal flow channel 12 through the end of the cross flow channel 14, and finally be discharged from the second longitudinal flow channel 12. In this mode, the coolant enters only through the first longitudinal channel 11 and exits through the second longitudinal channel 12, forming a single-inlet, single-outlet flow path. The third longitudinal channel 13 is blocked and does not participate in the drainage. Due to the single drainage path, the coolant travels a longer distance in the cross channel 14. Although the local flow velocity is increased, the overall heat exchange cycle is prolonged, and the actual cooling intensity tends to be mild, making it more suitable for working scenarios with low cooling requirements. For example, for some non-crystalline plastics (such as ABS), which have low glass transition temperatures, excessive cooling can easily cause internal stress cracking. This mode can avoid material performance damage caused by excessively rapid local cooling through gentle heat exchange in a single path, while reducing local temperature fluctuations caused by diversion, ensuring the stability of the product's surface quality.

[0065] Reference manual attached Figure 9Non-blocking working mode: When the third longitudinal channel 13 does not need to be blocked, the handle 16 is rotated in the opposite direction, causing the adjustable plug 15 to rotate, so that the second row of holes 18 rotates from the inside to the outside of the third longitudinal channel 13. At this time, the second row of holes 18 is connected to the external space of the mold, and the first row of holes 17 and the second row of holes 18 remain connected. During operation, the coolant simultaneously enters the cross channel 14 from the first longitudinal channel 11 and the second longitudinal channel 12. After the two coolant streams merge in the cross channel 14, they flow towards the center and enter the third longitudinal channel 13, and then are discharged sequentially through the first row of holes 17 in the adjustable plug 15 and the second row of holes 18 on the side. This mode, by using both the first longitudinal channel 11 and the second longitudinal channel 12 as inlets, forms a dual inlet path, which greatly increases the coolant flow rate and velocity in the cross channel 14, enhances the heat exchange efficiency per unit time, and is suitable for scenarios with high cooling requirements, such as thick-walled plastic parts or heat-sensitive plastics. The dual-inlet design can quickly remove the heat accumulated in the mold, avoiding product shrinkage or material degradation caused by insufficient cooling. At the same time, the centralized drainage path ensures sufficient flow of coolant in the cross channel 14, reducing local high-temperature dead zones.

[0066] Specifically, in use, the working mode after completely disassembling the adjustable plug is as follows: after the adjustable plug 15 is completely disassembled from the third longitudinal channel 13 (by unscrewing the threaded connection through the handle 16), the entire channel of the third longitudinal channel 13 is in a clear state.

[0067] The cooling mechanism also includes a temperature sensor 19, whose probe is located at the junction of the second longitudinal channel 12 and the cross channel 14. Specifically, the probe of the temperature sensor 19 is located at the junction of the second longitudinal channel 22 and the cross channel 14, which can monitor the water temperature at this critical location in real time, provide timely feedback on the cooling system status, and facilitate the adjustment of water flow and temperature according to the cooling requirements of different materials. This avoids problems such as uneven crystallization of crystalline plastics and internal stress cracking of non-crystalline plastics, ensuring cooling stability.

[0068] The temperature sensor 19 can be model number WZP-230.

[0069] Specifically, due to the differences in thermophysical properties and cooling requirements of different injection molding materials (such as crystalline plastics, non-crystalline plastics, heat-sensitive plastics, etc.), this mold, through the setting of the adjustable plug 15, can flexibly adjust the on / off state and flow rate of the third longitudinal flow channel 13. When processing products of different materials, the position of the adjustable plug 15 can be changed by rotating the handle 16, so that the second row of holes 18 is located inside or outside the third longitudinal flow channel 13, thereby controlling the drainage of the third longitudinal flow channel 13, and thus adjusting the overall flow rate and flow distribution of the cooling water circuit. Combined with the real-time monitoring of the temperature at the junction of the second longitudinal flow channel 22 and the cross flow channel 14 by the temperature sensor 19, the operating status of the cooling system can be grasped in a timely manner, which is convenient for dynamically adjusting the cooling parameters according to the cooling requirements of different materials, so that the mold can adapt to the cooling requirements of various injection molding materials, enhancing the versatility and applicability of the mold.

[0070] Reference manual attached Figures 4-6 Specifically, the cooling mechanism is arranged in a "C" shape around the molding cavity 20. The positions of the first longitudinal flow channel 11, the second longitudinal flow channel 22, the third longitudinal flow channel 13 and the transverse flow channel 14 avoid the key stress components of the mold, so as not to affect the overall strength and stability of the mold. The adjustable plug 15 adopts a threaded structure connection, which is convenient for installation, disassembly and maintenance. When the water channel is blocked or needs to be cleaned, the plug can be easily removed through the handle 16. The setting of the temperature sensor 19 provides a basis for the intelligent control of the cooling system, which makes it easy for operators to monitor the cooling status in real time and make corresponding adjustments, reducing the difficulty of operation and improving the practicality and maintenance convenience of the mold.
