Description

Technical Field

[0001] The present invention relates to the technical field of mold structure design, and particularly relates to a metal and plastic forming mold with efficient cooling. Background Art

[0002] Plastic forming molds inject molten plastics (such as PE, PP, ABS, etc.) into the cavity through processes such as injection molding and blow molding, and form plastic products with specific shapes after cooling. In the prior art, Chinese Patent CN215589867U discloses a plastic mold with a rapid cooling structure for formed workpieces. Through the settings of cooling grooves, circulation pipes, heat sinks, and cooling fans, after injection molding, cooling water is injected into the cooling grooves through the water inlet holes, and then the cooling water is kept flowing through the circulation pipes, enhancing the cooling effect. The heat sinks absorb heat from the outer wall of the lower mold cavity, and the motor drives the cooling fans to rotate, thereby accelerating the heat dissipation speed of the heat sinks. Finally, the high temperature is dissipated through the groove openings, so as to achieve rapid cooling and forming.

[0003] However, the above patent mainly relies on fixed cooling structures such as (cooling grooves, circulation pipes, heat sinks, and cooling fans), where the cooling water channels (such as circulation pipes) and the positions of the heat sinks are fixed and cannot dynamically adjust the cooling intensity according to the thermal distribution of the cavity. For example, the thick-walled areas of plastic products have high heat dissipation requirements, but the fixed cooling structure is difficult to specifically strengthen heat dissipation, resulting in lagging cooling in local overheated areas, causing plastic shrinkage deformation, warping, and even cracking (especially for high shrinkage rate materials such as PP and ABS). Moreover, the cooling fans and heat sinks rely on natural convection or one-way forced airflows, and the heat exchange efficiency is limited by the mold structure, with poor cooling uniformity and difficulty in meeting the heat dissipation requirements of complex cavities (such as products with multi-curves and large differences in thickness).

[0004] Therefore, a metal and plastic forming mold with efficient cooling is specifically designed to solve the above technical problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the above prior art, the present invention provides a metal and plastic forming mold with efficient cooling.

[0006] The technical solution of the present invention is: a hardware and plastic forming mold with efficient cooling, including a main mold, a sub-mold and a cooling water pipe pump. An injection hole is opened in the middle of the main mold. The side of the main mold is hermetically butted with the sub-mold. Matching forming grooves are opened in the middle of both the main mold and the sub-mold. Cooling water pipe pumps are slidably installed on both outer sides of the main mold and the sub-mold. The cooling water pipe pumps are connected to a stable pipe through a plurality of conveying hoses. The stable pipe is arranged around the outer side of the forming groove. The stable pipe is installed through the corresponding main mold and the inside of the sub-mold, and the stable pipes of both surround the outer side of the corresponding forming groove. A linkage plate is slidably arranged on the side of the mounting plate of each cooling water pipe pump. An oblique chute is opened on one side in the middle of the linkage plate. Both ends of the stable pipe pass through the corresponding stable plate and are connected to it. Heat dissipation plates are installed on both inner sides of the main mold and the sub-mold. Symmetric evacuation pipes are respectively communicated between the two heat dissipation plates of both. A pressure relief tank is connected to the outside of each evacuation pipe. A regulating tank is connected to the outside of the pressure relief tank. Pressure relief push frames are respectively slidably arranged between the oblique chutes of the linkage plates on both sides of the main mold and the sub-mold. A protruding part is arranged on the side of the pressure relief push frame. The protruding part of the pressure relief push frame slidably extends into the inside of the regulating tank, and a first spring is arranged between the protruding part and the regulating tank.

[0007] Further, the heat dissipation plate, the evacuation pipe, the pressure relief tank, the regulating tank, the pressure relief push frame and the first spring form a cooling group. When the pressure relief push frame slides along the oblique chutes on both sides, it drives the linkage plates on both sides to move synchronously, driving the cooling water pipe pump, the conveying hose and the stable pipe to move together, realizing dynamic heat dissipation.

[0008] Further, confluence cavities are opened in the lower parts of both the main mold and the sub-mold. The discharge ends of the evacuation pipes are communicated with the upper parts inside the confluence cavities.

[0009] Further, wedge-shaped parts protruding outwards are arranged on both the upper and lower sides of each linkage plate.

[0010] Further, it also includes a horizontal adjusting frame and a second spring. Horizontal adjusting frames are arranged on the outer sides of the two stable pipes at the uppermost and lowermost parts inside the main mold and the sub-mold. A guide rod is arranged on the side of the horizontal adjusting frame. The guide rod is slidably connected to the inside of the corresponding main mold and the sub-mold. A second spring is arranged at the sliding connection of the guide rod corresponding to the main mold and the sub-mold. In addition, both ends of the horizontal adjusting frame are wedge-shaped. The wedge-shaped parts of the horizontal adjusting frames on the upper parts of the main mold and the sub-mold are in sliding contact with the upper wedge-shaped parts of the linkage plates, realizing the inward movement of the cooling group. The wedge-shaped parts of the horizontal adjusting frames on the lower parts of the main mold and the sub-mold are in sliding contact with the lower wedge-shaped parts of the linkage plates, realizing the outward movement of the cooling group.

[0011] Furthermore, it also includes a push rod, an extrusion plate, a water storage tank, a water inlet pipe, and a spraying module. Both ends of the two push frames are close to being exposed outside the inclined chute, and upwardly bent push rods are provided at both ends of the push frames. An extrusion plate is provided at the upper end of the push rod. A water storage tank is installed on one side of the upper part of the main mold and the auxiliary mold near the corners. The extrusion plate is slidably connected to the inside of the water storage tank. The upper part of the water storage pipe is communicated with the water inlet pipe. Spraying modules are installed on both sides of the upper part inside the main mold and the auxiliary mold, and the spraying modules are connected to the water storage tank.

[0012] Furthermore, the spraying ends of the two spraying modules in the upper part inside the main mold and the auxiliary mold are arranged facing each other, and the heat dissipation plate is located below the corresponding two spraying modules.

[0013] Furthermore, it also includes an air intake hood, a discharge pipe, and a heat dissipation fan. Intake hoods penetrating to the outside are communicated with both sides of the upper part of the confluence chamber inside the main mold and the auxiliary mold. A filter screen is provided inside the intake end of the intake hood. Discharge pipes are communicated with both sides of the lower part of the confluence chamber. Heat dissipation fans are respectively installed on the upper parts of the main mold and the auxiliary mold.

[0014] The beneficial effects of the present invention are as follows: 1. A mechanical linkage system is formed by the cooling groups on both sides of the main mold and the auxiliary mold, enabling the heat inside the two molds to be conducted to the pressure relief tank through the heat dissipation plate, triggering the pressure relief push frame to slide along the inclined chute, driving the overall displacement of the cooling water pipe pump and the stabilizing pipe, and realizing the dynamic adjustment of the cooling path according to the thermal distribution of the cavity. Compared with the traditional fixed cooling structure, the cooling efficiency is improved, and the plastic shrinkage deformation caused by local overheating is avoided.

[0015] 2. Through the combination of the pressure relief tank and the adjustment tank, according to the air pressure change and the spring one reset mechanism, the moving amplitude of the cooling component is automatically adjusted. When the mold temperature rises, the air pressure in the pressure relief tank pushes the cooling group to strengthen heat dissipation; after the temperature drops, the spring one resets, and the cooling intensity is adaptively weakened, realizing the dynamic balance between energy consumption and cooling demand.

[0016] 3. The confluence chamber is integrated into the lower parts of the main mold and the auxiliary mold, and is communicated with the evacuation pipe, the air intake hood, and the discharge pipe to form a forced convection heat dissipation channel. The sprayed water vapor and the external cold air are mixed in the confluence chamber and are forcibly discharged through the heat dissipation fan, improving the heat exchange efficiency and shortening the single injection molding cooling cycle.

[0017] 4. Through the sliding fit between the wedge-shaped parts on the upper and lower sides of the linkage plate and the wedge-shaped end faces of the transverse adjustment frame, it is ensured that the cooling group is accurately positioned along the preset path during movement, which is suitable for directional enhanced cooling of the thick-walled areas of complex cavities; the transverse adjustment frame realizes elastic reset through the guide rod and the spring two, avoiding jamming when the cooling group is displaced. The spring two provides a reverse force to ensure that the stabilizing pipe quickly returns to its position after dynamic adjustment, improving the rhythm stability of continuous injection molding.

[0018] 5. Spray cooling water onto the surface of the heat dissipation plate through the spraying module and the pressing plate to pressurize and atomize it, and utilize the principle of evaporation heat absorption to rapidly cool down. The water storage tank and the water inlet pipe form an independent water supply system, avoiding interference with the main cooling water path and improving the cooling rate in the local area.

[0019] 6. Prevent foreign objects from entering through the filter screen inside the air intake hood. The external cold air is mixed with the high-temperature water vapor through the confluence cavity. The cooling fan adjusts the wind speed through frequency conversion control to form a controllable negative pressure air flow cycle. Compared with natural heat dissipation, the overall temperature drop speed of the mold is increased, and the risk of condensate accumulation inside the mold can be reduced.

It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Embodiment: A metal and plastic forming mold with efficient cooling, as Figures 1-11 and Figure 13As shown in the figure, it includes a main mold 1, a sub-mold 2 and a cooling water pipe pump 3. An injection hole 11 is opened in the middle of the main mold 1. The side of the main mold 1 is hermetically butted with the sub-mold 2. After the main mold 1 and the sub-mold 2 are closed, a complete cavity is formed to accommodate molten plastic and form products. At the same time, it integrates a cooling system, a heat dissipation component and a dynamic adjustment mechanism, serving as an installation carrier for functional modules. During operation, the hermetic butt joint is driven by a hydraulic cylinder to ensure the clamping accuracy. Matching forming grooves are opened in the middle of both the main mold 1 and the sub-mold 2. Cooling water pipe pumps 3 are slidably installed on both outer sides of the main mold 1 and the sub-mold 2. A plurality of conveying hoses 31 are connected to the side of the cooling water pipe pump 3. A stabilizing pipe 32 is connected between the plurality of conveying hoses 31 on each side of the main mold 1 and the sub-mold 2. Through the connection of the conveying hose 31 and the stabilizing pipe 32, a flexible connection is formed to adapt to dynamic displacement. The stabilizing pipe 32 is installed through the corresponding main mold 1 and sub-mold 2, and the stabilizing pipes 32 of both surround the corresponding forming groove on the outside. The heat of the cavity is directly absorbed by the flowing cooling water to achieve uniform heat dissipation. The cooling water pipe pump 3 drives the circulation of the cooling water, and the cooling water is conveyed to the stabilizing pipe 32 through the conveying hose 31 to form a basic cooling circuit. A linkage plate 33 is slidably arranged on the side of the mounting plate of each cooling water pipe pump 3. An inclined chute is opened on one side of the middle of the linkage plate 33. Both ends of the stabilizing pipe 32 pass through the corresponding stabilizing plate and are connected to it. Wedge-shaped parts protruding outward are provided on both the upper and lower sides of each linkage plate 33. Heat dissipation plates 4 are installed on both inner sides of the main mold 1 and the sub-mold 2. Symmetric evacuation pipes 41 are respectively connected between the two heat dissipation plates 4 of both. The heat dissipation plate 4 is closely attached to the inner wall of the cavity of the main mold 1 and the sub-mold 2, absorbs the heat of the cavity through heat conduction, and transfers it to the evacuation pipe 41. Confluence cavities 70 are opened in the lower parts of both the main mold 1 and the sub-mold 2. The discharge end of the evacuation pipe 41 is connected to the upper part inside the confluence cavity 70. A pressure relief tank 42 is connected to the outside of each evacuation pipe 41. The evacuation pipe 41 conveys the heat absorbed by the heat dissipation plate 4 to the pressure relief tank 42, serving as a heat transfer medium channel. A regulating tank 43 is connected to the outside of the pressure relief tank 42. The pressure relief tank 42 and the regulating tank 43 are connected in series by a flange or thread to form a pneumatic balance system. Pressure relief push frames 44 are respectively slidably arranged between the inclined chutes of the linkage plates 33 on both sides of the main mold 1 and the sub-mold 2. The pressure relief tank 42 receives the heat conveyed by the evacuation pipe 41, and the internal air pressure rises and injects into the regulating tank 43, thereby pushing the pressure relief push frame 44 to move; the linkage plate 33 converts the air pressure signal into mechanical displacement through the cooperation of the inclined chute and the pressure relief push frame 44. A protruding part is provided on the side of the pressure relief push frame 44. The protruding part of the pressure relief push frame 44 slides into the inside of the regulating tank 43, and a spring 45 is arranged between the protruding part and the regulating tank 43 to provide a reset force, which pushes the pressure relief push frame 44 to reset when the air pressure decreases. The linkage plate 33 is linked with the horizontal adjusting frame 5 through the wedge-shaped part to drive the dynamic adjustment of the position of the cooling system;The heat dissipation plate 4, the evacuation pipe 41, the pressure relief tank 42, the adjustment tank 43, the pressure relief push frame 44 and the first spring 45 form a cooling group. When the pressure relief push frame 44 slides along the inclined chutes on both sides, it drives the linkage plates 33 on both sides to move synchronously, driving the cooling water pipe pump 3, the delivery hose 31 and the stabilizing pipe 32 to move together, realizing dynamic heat dissipation.

[0037] As Figure 1 and Figures 9-11 shown, it further includes a horizontal adjustment frame 5 and a second spring 51. Horizontal adjustment frames 5 are provided outside the two stabilizing pipes 32 at the uppermost and lowermost parts inside the main mold 1 and the sub-mold 2. The horizontal adjustment frame 5 meshes with the wedge-shaped part of the linkage plate 33 through a wedge-shaped surface, converting the horizontal displacement of the linkage plate 33 into the longitudinal displacement of the cooling system. A guide rod is provided on the side of the horizontal adjustment frame 5, and this guide rod is slidably connected to the inside of the corresponding main mold 1 and sub-mold 2, and a second spring 51 is provided at the sliding connection of the guide rod corresponding to the main mold 1 and sub-mold 2. The second spring 51 maintains the neutral position of the horizontal adjustment frame 5 to avoid the cooling system interfering with the mold closing or mold opening actions. In addition, both ends of the horizontal adjustment frame 5 are wedge-shaped. The wedge-shaped parts of the horizontal adjustment frames 5 on the upper part of the main mold 1 and the sub-mold 2 are in sliding contact with the upper wedge-shaped parts of the linkage plates 33, realizing the inward movement of the cooling group. The wedge-shaped parts of the horizontal adjustment frames 5 on the lower part of the main mold 1 and the sub-mold 2 are in sliding contact with the lower wedge-shaped parts of the linkage plates 33, realizing the outward movement of the cooling group.

[0038] As Figure 11 and Figure 12 shown, it further includes a push rod 6, an extrusion plate 60, a water storage tank 61, a water inlet pipe 62 and a spraying module 63. Both ends of the two push frames are close to being exposed from the inclined chutes, and push rods 6 that bend upward are provided at both ends of the push frames. An extrusion plate 60 is provided at the upper end of the push rod 6. A water storage tank 61 is installed on one side of the upper part of the main mold 1 and the sub-mold 2 near the corners. The extrusion plate 60 is slidably connected to the inside of the water storage tank 61. The upper part of the water storage pipe is communicated with the water inlet pipe 62. The water storage tank 61 stores cooling water and replenishes the water source through the water inlet pipe 62. Spraying modules 63 are installed on both sides of the upper part inside the main mold 1 and the sub-mold 2. The push rod 6 drives the displacement of the pressure relief push frame 44 to trigger the action of the spraying module 63. The extrusion plate 60 compresses the water storage tank 61 through linear displacement to pressurize and convey the cooling water. The spraying module 63 is connected to the water storage tank 61. The water storage tank 61 is connected to the spraying module 63 by threading or quick connection through a pipeline. The spraying module 63 atomizes and sprays the pressurized cooling water onto the surface of the heat dissipation plate 4 to enhance the evaporation heat dissipation effect. The spraying ends of the two spraying modules 63 on the upper part inside the main mold 1 and the sub-mold 2 are arranged facing each other, and the heat dissipation plate 4 is located below the corresponding two spraying modules 63.

[0039] As Figure 4 and Figure 13As shown, it further includes an air inlet hood 7, a discharge pipe 701, and a cooling fan 71. On both sides of the upper part of the confluence chamber 70 at the lower part inside the main mold 1 and the sub-mold 2, there are air inlet hoods 7 that penetrate to the outside. The air inlet hood 7 and the confluence chamber 70 are hermetically connected by flanges or welding. A filter screen is provided inside the air inlet end of the air inlet hood 7 to suck in ambient cold air to form a forced convection air flow. On both sides of the lower part of the confluence chamber 70, there are connected discharge pipes 701 for discharging high-temperature air flow to maintain a negative pressure cycle. The cooling fans 71 are respectively installed on the main mold 1 and the sub-mold 2 by bolts to adjust the air flow speed and improve the heat dissipation efficiency.

[0040] During use, the main mold 1 and the auxiliary mold 2 are accurately aligned and closed through an externally installed hydraulic cylinder. The forming grooves of the two form a complete cavity. The linkage plate 33 is in the initial position. The cooling water pipe pumps 3 on both sides inject cooling water into the stabilizing pipe 32 through the delivery hoses 31. The stabilizing pipe 32 forms a basic water cooling cycle around the outside of the forming groove to pre-lower the mold temperature in advance. The lateral adjustment frame 5 is in the middle position under the action of the second spring 51 to avoid the cooling component interfering with the mold closing action. The molten plastic fills the cavity through the injection hole 11 in the middle of the main mold 1. At this time, the internal temperatures of the main mold 1 and the auxiliary mold 2 rise rapidly. The heat dissipation plate 4 absorbs the heat of the cavity through heat conduction. The heat is transferred to the pressure relief tank 42 and the adjustment tank 43 through the evacuation pipe 41. The air pressure in the adjustment tank 43 gradually rises. The cooling water pipe pump 3 continuously pumps cooling water. The water flow in the stabilizing pipe 32 uniformly dissipates heat from the forming groove through the pipeline path to avoid plastic shrinkage and deformation caused by local overheating. The evacuation pipe 41 conveys the heat absorbed by the heat dissipation plate 4 to the pressure relief tank 42, and then the pressure relief tank 42 injects it into the adjustment tank 43. The air pressure in the adjustment tank 43 pushes the pressure relief push frame 44 to slide outward along the inclined chute of the linkage plate 33, compressing the first spring 45. When the air pressure in the pressure relief tank 42 reaches the threshold value, the protruding part of the pressure relief push frame 44 pushes the linkage plate 33 to move synchronously, driving the overall displacement of the cooling water pipe pumps 3 and the stabilizing pipe 32 on both sides. The lateral adjustment frame 5 is squeezed by the wedge-shaped part of the linkage plate 33 and slides through the guide rod to compress the second spring 51, so that the stabilizing pipe 32 dynamically adjusts the cooling position along the shape of the cavity. For example, it strengthens the cooling for thick-walled areas. The movement path of the stabilizing pipe 32 matches the thermal distribution of the cavity, and the adaptive cooling intensity adjustment is realized through mechanical linkage. When the linkage plate 33 moves, the push rod 6 at its end displaces with the pressure relief push frame 44 to trigger the action of the extrusion plate 60, pressurizing and conveying the cooling water stored in the water storage tank 61 to the spraying module 63. The spraying module 63 sprays atomized cooling water onto the surface of the heat dissipation plate 4 inside the main mold 1 and the auxiliary mold 2, further reducing the mold temperature by evaporation heat absorption, while avoiding the water flow directly impacting the plastic product. After the sprayed water mist contacts the heat dissipation plate 4, it evaporates, and the water vapor flows downward through the confluence chamber 70 and mixes with the external cold air inhaled by the air intake hood 7. At the same time, the heat dissipation fan 71 is started, and the forced air flow is discharged out of the mold through the discharge pipe 701 to form a negative pressure cycle, accelerating the heat exchange efficiency. And the air intake hood 7 inhales the ambient cold air through the filter screen. The air flow passes through the confluence chamber 70 and contacts the surface of the heat dissipation plate 4 through the evacuation pipe 41 to absorb the residual heat. The high-temperature air flow is led out by the discharge pipe 701. The heat dissipation fan 71 adjusts the air speed through frequency conversion control to match the real-time temperature requirement of the mold. Part of the high-temperature air flow enters the adjustment tank 43 and absorbs the waste heat through the phase change material layer (such as paraffin-based composite material) in the adjustment tank 43. The phase change material melts and stores heat, extending the intermittent time of the active cooling system. When the temperatures of the main mold 1 and the auxiliary mold 2 drop to the set threshold value, the air pressure in the pressure relief tank 42 decreases, and the first spring 45 pushes the pressure relief push frame 44 to reset. The linkage plate 33 and the cooling water pipe pump 3 return to the initial position to prepare for the next cycle;In addition, before the mold is opened, the cooling water pipe pump 3 stops supplying water, the spraying module 63 is closed, and the lateral adjusting frame 5 is reset under the action of the second spring 51 to ensure that the stabilizing pipe 32 is disengaged from the cavity area. Then, the formed plastic product is ejected by hydraulic drive, and the wedge-shaped part of the linkage plate 33 is disengaged from the lateral adjusting frame 5 to avoid interfering with the demolding action.;

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
