Description

Technical Field

[0001] This application relates to the field of injection molding technology, and particularly to a mold. Background Art

[0002] With the rapid development of the automotive industry, consumers' requirements for the appearance of automobiles are increasing day by day. As important components of automobiles, products such as vehicle lamps also have higher and higher requirements from consumers. In the injection molding process of products such as vehicle lamps, the design of the gate has a crucial impact on the appearance quality of products such as vehicle lamps. In response to the trend that consumers have higher and higher requirements for the appearance of products such as vehicle lamps, it is usually required that the gate is not visible in appearance to achieve a more beautiful and delicate appearance. Moreover, with the continuous improvement of the automation level in the production process of products such as vehicle lamps, consumers also have higher and higher requirements for aspects such as the production efficiency and cost control of products such as vehicle lamps, and it is usually required that the gate can be automatically separated.

[0003] Current gate types include: pin gate, side gate, bottom gate, and submarine gate. Among them, the pin gate is controlled by a hot runner valve pin and can achieve automatic gate separation. However, the pin gate is located on the outer surface of products such as vehicle lamps, visible and touchable in appearance, seriously affecting the aesthetics of products such as vehicle lamps. The side gate is usually set at the edge of products such as vehicle lamps, having the problem of partial appearance visibility, and cannot be automatically separated, requiring subsequent manual removal, which is likely to cause gate residue and interfere with the assembly of products such as vehicle lamps. The bottom gate is usually set at the bottom edge of products such as vehicle lamps, mostly invisible in appearance, but still requires post-treatment removal, cannot achieve automatic separation, and also has the risk of gate residue interfering with the assembly of products such as vehicle lamps. The submarine gate is usually located inside or in an inconspicuous position of products such as vehicle lamps, so it is almost invisible in the appearance of products such as vehicle lamps. Moreover, the submarine gate design can be used in conjunction with automated equipment to achieve automatic gate separation, helping to reduce the dependence on manual operations and improve production efficiency. Therefore, generally, the submarine gate is adopted to meet the requirements of users for the gate to be invisible in appearance and for the gate to be able to achieve automatic separation.

[0004] However, when using a submarine gate in brittle injection molded products, due to the high rigidity and brittleness of brittle injection plastics, it is easy to break in the gate area, resulting in gate blockage, affecting the normal production of the mold and the integrity of products such as vehicle lamps. Summary of the Invention

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0034] Please refer to Figure 1, an embodiment of the present application provides a mold. The mold has a first direction M, a second direction N, and a third direction P that intersect pairwise. In this embodiment, the first direction M, the second direction N, and the third direction P are perpendicular to each other. The fact that the first direction M, the second direction N, and the third direction P are perpendicular to each other can be understood as the included angles between any two of the first direction M, the second direction N, and the third direction P being 80° to 90°, which is not limited herein.

[0035] Please refer to Figures 1 - 4 , the mold includes a template 1. The template 1 is usually made of high-strength steel, such as P20, H13, etc., to ensure the wear resistance and durability of the mold. The template 1 has a receiving cavity 11. Specifically, the receiving cavity 11 includes a first receiving cavity 111, a second receiving cavity 112, and a third receiving cavity 113 arranged along the first direction M, and the first receiving cavity 111 communicates between the second receiving cavity 112 and the third receiving cavity 113.

[0036] Please refer to together Figures 1 - 3 and Figures 5 - 8 , the mold further includes an insert 2, and the insert 2 is arranged in the receiving cavity 11. The insert 2 is usually made of high-strength steel, such as P20, H13, etc., to ensure the wear resistance and durability of the mold. A horn runner 201 is provided in the insert 2. The horn runner 201 is used to guide the injection molding material to the mold core 6 to form an injection molded product. Specifically, the insert 2 includes a horn insert 21 and a runner thimble insert 22. The horn runner 201 is arranged in the horn insert 21, and a sub-runner 202 is provided in the runner thimble insert 22. The horn runner 201 communicates with the sub-runner 202, and the sub-runner 202 is used to communicate with the injection head. Among them, the horn insert 21 is arranged in the first receiving cavity 111, and the runner thimble insert 22 is arranged in the second receiving cavity 112. Please refer to together Figure 3 、 Figures 6 - 8The horn insert 21 includes a first insert block 211 and a second insert block 212 that are spliced together. The first insert block 211 and the second insert block 212 are arranged along the second direction N. The horn runner 201 is formed by splicing the first insert block 211 and the second insert block 212. In this embodiment, the first insert block 211 is fixed in the first receiving cavity 111 of the template 1 through a first fastener 2111, the second insert block 212 is fixed in the first receiving cavity 111 of the template 1 through a second fastener 2121, and the runner ejector insert 22 is fixed in the second receiving cavity 112 of the template 1 through a third fastener 221. In this embodiment, the first fastener 2111, the second fastener 2121, and the third fastener 221 all extend along the third direction P. Among them, both the horn insert 21 and the runner ejector insert 22 can be made of 1.2343 ESR steel (also known as H11 ESR steel). 1.2343 ESR steel has high wear resistance and can withstand the friction and wear caused by the flow of brittle injection plastics. It has excellent toughness and can reduce the risk of cracking or breaking of the insert 2 during use. In this embodiment, the specific heat of the steel of the horn insert 21 is 460 J / kg - °C, so the horn insert 21 can be quickly heated. In other embodiments, the horn insert 21 can use steel with other specific heats, and the present application does not limit this.

[0037] Please refer to Figure 2 The mold further includes a runner ejector pin 9 and a product ejector pin 10. The runner ejector pin 9 can slide relative to the runner ejector insert 22 to eject the injection waste in the sub - runner 202 and the horn runner 201. The product ejector pin 10 can slide relative to the mold core 6 to eject the injection product 100 on the mold core 6. The injection product 100 and the injection waste are separated at the horn gate 203. Since the brittle injection plastic has high rigidity and brittleness, it is prone to breakage, resulting in gate blockage, which affects the normal production of the mold and the integrity of products such as vehicle lamps.

[0038] Please refer to together Figure 2 、 Figure 7 and Figure 8 The mold further includes a heating assembly 3. The heating assembly 3 is arranged in the receiving cavity 11. The heating assembly 3 is correspondingly arranged with the horn insert 21 and is used to heat the injection plastic in the horn runner 201. By heating the injection plastic in the horn runner 201 through the heating assembly 3, the injection plastic (for example, polymethyl methacrylate, abbreviated as PMMA) in the horn runner 201 is heated to the glass transition temperature (for example, the glass transition temperature of PMMA is 107 °C) to present a high - elastic state. When the horn gate 203 is automatically separated, it can prevent the injection plastic in the horn runner 201 from breaking and blocking the horn runner 201 and the horn gate 203, thereby improving the production efficiency of the mold and the integrity of the products formed by the mold preparation.

[0039] Please refer to togetherFigure 2 , Figures 7 - 9 , the heating component 3 is correspondingly arranged below the horn insert 21. Among them, the heating component 3 includes: a heat conducting member 31 and a heating member 32. The heat conducting member 31 is correspondingly arranged below the horn runner 201; one end of the heating member 32 is connected to the heat conducting member 31, and the other end of the heating member 32 is used for connecting to the temperature control component. In this embodiment, the heating member 32 extends along the third direction P, and one end thereof extends into the heat conducting member 31 from the second surface 312 of the heat conducting member 31, so that the heat released by the heating member 32 can be efficiently conducted to the heat conducting member 31. Among them, the heating member 32 can be a heating wire made of high nickel alloy. The temperature control component can be a temperature control box, and the heat release of the heating wire is controlled through the temperature control box to prevent the temperature of the horn insert 21 from being too high, which may cause the temperature of other components of the mold to be abnormal and affect the normal production of the mold. The heat conducting member 31 is used to increase the contact area between the heating member 32 and the horn insert 21, and further can quickly and efficiently conduct the heat released by the heating member 32 to the horn insert 21.

[0040] Please refer to Figure 7 , both the first fastener 2111 and the second fastener 2121 pass through the heat conducting member 31 to be connected to the template 1. That is, the first fastener 2111 is not only used to fix the first insert block 211 and the template 1, but also used to fix the heat conducting member 31 and the template 1; the second fastener 2121 is not only used to fix the second insert block 212 and the template 1, but also used to fix the heat conducting member 31 and the template 1.

[0041] Please refer to Figure 2 , Figure 5 , Figure 8 and Figure 9 , the heat conducting member 31 includes a side surface and relatively arranged first surface 311 and second surface 312. The first surface 311 is located on the side of the second surface 312 close to the horn runner 201, and the side surface is connected between the first surface 311 and the second surface 312. Specifically, the first surface 311 and the second surface 312 are the upper surface and the lower surface of the heat conducting member 31 in the third direction P, and the side surface includes a first side surface 313 and a second side surface 314 of the heat conducting member 31 in the first direction M and a third side surface 315 and a fourth side surface 316 of the heat conducting member 31 in the second direction N.

[0042] Please refer to Figure 2 , Figure 5 , Figure 8 and Figure 9 , the mold further includes a heat insulation component 4, and the heat insulation component 4 is arranged between the heating component 3 and the mold core 6. By arranging the heat insulation component 4 between the heating component 3 and the mold core 6, the heat insulation component 4 is used to block the heat of the heating component 3 to prevent the heat of the heating component 3 from being conducted to the injection molding material on the mold core 6 and avoid affecting the quality of the injection molded product formed on the mold core 6.

[0043] Please refer to Figure 2 、 Figure 5 、 Figure 8 and Figure 9 , the heat insulation component 4 includes a heat insulation insert 402. The heat insulation insert 402 is at least partially disposed above the horn insert 21. A horn gate 203 is provided in the heat insulation insert 402, and the horn gate 203 communicates with the horn runner 201. Among them, the heat insulation insert 402 is fixed to the horn insert 21 by a fourth fastener 4021. The fourth fastener 4021 extends along the third direction P. By at least partially disposing the heat insulation insert 402 above the horn insert 21, the heat on the horn insert 21 can be prevented from conducting upward, avoiding the heat of the horn insert 21 from affecting the molding of the injection molding material in other parts. Among them, the material of the heat insulation insert 402 can be titanium alloy (the thermal conductivity of titanium alloy is 7.955 W / m·k). Titanium alloy has excellent strength-to-weight ratio, can provide sufficient structural strength while maintaining light weight, and titanium alloy has low thermal conductivity. Therefore, the low thermal conductivity of titanium alloy can be used to effectively reduce heat transfer and provide good heat insulation effect.

[0044] Please refer to Figure 2 、 Figure 5 、 Figure 8 and Figure 9 , the heat insulation component 4 further includes: a heat insulation plate 401. The heat insulation plate 401 at least partially covers the heating component 3. Specifically, the heat insulation plate 401 is disposed on the second surface 312 and / or on the side surface. The heat insulation plate 401 can be composed of glass fiber and a composite material with high heat resistance. By the heat insulation plate 401, the heat of the heating component 3 is prevented from being conducted to the runner ejector pin insert 22 or the mold core 6 adjacent to the horn insert 21, thereby avoiding the heat of the heating component 3 from affecting the molding of the injection molding material in other parts.

[0045] Please refer to Figure 8 and Figure 9, the heat insulation plate 401 in this embodiment includes: a first heat insulation plate 41, a second heat insulation plate 42, a third heat insulation plate 43, a fourth heat insulation plate 44, and a fifth heat insulation plate 45. The first heat insulation plate 41, the second heat insulation plate 42, the third heat insulation plate 43, the fourth heat insulation plate 44, and the fifth heat insulation plate 45 are respectively disposed on the first side surface 313, the second side surface 314, the third side surface 315, the fourth side surface 316, and the second surface 312. Among them, the first heat insulation plate 41 is fixedly connected to the mold core 6 through a fifth fastener 411, the second heat insulation plate 42 is fixedly connected to the runner ejector pin insert 22 through a sixth fastener 421, the third heat insulation plate 43 is fixedly connected to the template 1 through a seventh fastener 431, the fourth heat insulation plate 44 is fixedly connected to the template 1 through an eighth fastener 441, and the fifth heat insulation plate 45 is fixedly connected to the template 1 through a ninth fastener 451. Among them, the fifth fastener 411 and the sixth fastener 421 extend along the first direction M, the seventh fastener 431 and the eighth fastener 441 extend along the second direction N, and the ninth fastener 451 extends along the third direction P.

[0046] By providing the heat insulation plates 401 on both the side surface and the second surface 312 of the heat conducting member 31, it is possible to preferably prevent the heat of the heating assembly 3 from being conducted to the runner ejector pin insert 22 or the mold core 6 adjacent to the horn insert 21, thereby avoiding the heat of the heating assembly 3 from affecting the injection molding of other parts.

[0047] Please refer to Figure 5 , Figure 7 and Figure 9, in the first direction M, one end of the heat insulation insert 402 away from the runner thimble insert 22 covers the first heat insulation plate 41, and the edge of the end of the heat insulation insert 402 away from the runner thimble insert 22 is flush with the edge of the end of the first heat insulation plate 41 away from the runner thimble insert 22. In the first direction M, one end of the heat insulation insert 402 close to the runner thimble insert 22 covers the second heat insulation plate 42, and the edge of the end of the heat insulation insert 402 close to the runner thimble insert 22 is flush with the edge of the end of the second heat insulation plate 42 close to the runner thimble insert 22. In the second direction N, one end of the heat insulation insert 402 away from the second insert block 212 covers the third heat insulation plate 43, and the edge of the end of the heat insulation insert 402 away from the second insert block 212 is flush with the edge of the end of the third heat insulation plate 43 away from the second insert block 212. In the second direction N, one end of the heat insulation insert 402 away from the first insert block 211 covers the fourth heat insulation plate 44, and the edge of the end of the heat insulation insert 402 away from the first insert block 211 is flush with the edge of the end of the fourth heat insulation plate 44 away from the first insert block 211. In the third direction P, the fifth heat insulation plate 45 is arranged below the first heat insulation plate 41, the second heat insulation plate 42, the third heat insulation plate 43, and the fourth heat insulation plate 44. The two outer edges of the fifth heat insulation plate 45 in the first direction M are flush with the two outer edges of the heat insulation insert 402 in the first direction M, and the two outer edges of the fifth heat insulation plate 45 in the second direction N are flush with the two outer edges of the heat insulation insert 402 in the second direction N. In summary, a receiving cavity can be formed by the mutual cooperation of the first heat insulation plate 41, the second heat insulation plate 42, the third heat insulation plate 43, the fourth heat insulation plate 44, the fifth heat insulation plate 45, and the heat insulation insert 402. The heat conducting member 31 is located in the receiving cavity, which can improve the heat insulation effect on the heat conducting member 31.

[0048] Please refer to Figure 5 and Figure 7 , the mold further includes: a first temperature sensing member 5. One end of the first temperature sensing member 5 is connected to the horn insert 21 to sense the temperature of the horn insert 21, and the other end of the first temperature sensing member 5 is used to connect to the temperature control component. In this embodiment, the first temperature sensing member 5 includes: a first sub-temperature sensing member 51 and a second sub-temperature sensing member 52. The first sub-temperature sensing member 51 is connected between the first insert block 211 and the temperature control component, and the second sub-temperature sensing member 52 is connected between the second insert block 212 and the temperature control component. The temperature of the first insert block 211 is sensed by the first sub-temperature sensing member 51, and then the heating component 3 is adjusted by the temperature control component to control the temperature of the horn insert 21 within the target range, so as to avoid the temperature of the horn insert 21 being too high, which may cause the temperature of other components of the mold to be abnormal and affect the normal production of the mold. The temperature of the second insert block 212 is sensed by the second sub-temperature sensing member 52, and then the heating component 3 is adjusted by the temperature control component to control the temperature of the horn insert 21 within the target range, so as to avoid the temperature of the horn insert 21 being too high, which may cause the temperature of other components of the mold to be abnormal and affect the normal production of the mold.

[0049] Please also refer to Figure 2 、 Figures 10 - 11 The mold further includes a mold core 6. The mold core 6 is disposed in the accommodating cavity 11 and on a side of the horn insert 21 away from the runner thimble insert 22. Specifically, the mold core 6 is disposed in the third accommodating cavity 113.

One end of the second temperature sensing element 7 is connected to the mold core 6 to sense the temperature of the mold core 6, and the other end of the second temperature sensing element 7 is used to connect to a temperature control component. In some embodiments, the temperature of the mold core 6 can be sensed by the second temperature sensing element 7, and then the heating component 3 can be adjusted through the temperature control component to control the temperature of the horn insert 21 within a target range, avoiding abnormal temperatures of other components of the mold caused by too high a temperature of the horn insert 21 and preventing it from affecting the normal production of the mold.

[0051] Please also refer to Figure 2 、 Figures 10 - 11 The mold further includes a heat exchange component 8. The heat exchange component 8 is at least partially disposed in the mold core 6.

One end of the heat exchange pipe 83 communicates with the inlet pipe 81, and the other end of the heat exchange pipe 83 communicates with the outlet pipe 82. When the temperature of the mold core 6 is on the high side, a coolant (such as water) enters the heat exchange pipe 83 through the inlet pipe 81. The coolant in the heat exchange pipe 83 exchanges heat with the mold core 6 to cool the mold core 6, and the coolant after heat exchange is recycled through the outlet pipe 82.
