Description

Technical Field

[0001] This application relates to the field of refrigerator drawer manufacturing technology, and in particular to a refrigerator drawer injection mold. Background Technology

[0002] Injection molds are tools used for injection molding of plastics, giving products a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and after cooling and solidification, obtaining the molded product. This production method is now widely used in the production of refrigerator plastic parts.

[0003] Injection molds are composed of many steel plates and various parts, generally including molding devices, positioning devices, cooling systems, temperature control systems, runner systems, etc. During injection molding, the mold is mounted on the injection molding machine, and the plastic is injected into the mold from the runner system for cooling and shaping.

[0004] However, before and after injection molding, the injection runner is in an open state, and some dust can easily enter the cavity from the runner, resulting in poor product quality after molding. Summary of the Invention

[0005] The purpose of this application is to provide a refrigerator drawer injection mold with higher product quality.

[0006] Firstly, the refrigerator drawer injection mold provided in this application adopts the following technical solution:

[0007] A refrigerator drawer injection mold includes a moving mold base, a fixed mold base, an injection nozzle, and a side parting mechanism. The moving mold base is slidably connected to the fixed mold base, the side parting mechanism is slidably connected to the moving mold base, and the injection nozzle is placed on the fixed mold base.

[0008] The injection nozzle has an injection channel for dispensing adhesive and a sealing hole symmetrically arranged relative to the injection channel. The sealing hole is connected to the injection channel and a sealing element for sealing the injection channel is provided in the sealing hole. The lateral parting mechanism can drive the sealing element to exit the injection channel.

[0009] By adopting the above technical solution, before and after injection molding, the sealing component extends from the sealing hole into the injection runner, at which point the injection runner is in a closed state. After preparation is complete, the lateral parting mechanism retracts, pushing the sealing component back into the sealing hole, at which point the injection runner is in an open state. Subsequently, the injection molding machine quickly injects plastic into the injection runner. After cooling, the product is molded. The sealing component can seal the injection runner when not in use, preventing dust from entering the mold and improving product quality.

[0010] Optionally, it also includes a hot melt component for heating the injection nozzle, wherein the injection nozzle has an outlet hole for accommodating the hot melt component, and the hot melt component is placed in the outlet hole.

[0011] When demolding a product, some raw materials will cool and solidify in the injection runner and be ejected from the mold along with the product. After the product is formed, this part will be removed, which is the waste part. By adopting the above technical solution, this waste part will be heated by the hot melt to keep it in a fluid state and injected into the mold in the next injection, reducing the raw material loss during product production.

[0012] Optionally, the lateral parting mechanism can also control the opening and closing of the hot melt component. When the plug extends into the injection molding channel, the hot melt component is in a closed state, and when the plug exits the injection molding channel, the hot melt component is in a working state.

[0013] By adopting the above technical solution, before injection molding, the sealing component blocks the injection runner to prevent dust from entering. During injection molding, the sealing component exits the injection runner, and the injection molding machine injects plastic into the injection runner. The hot melt component begins to heat the injection nozzle to ensure a stable plastic flow rate. After injection molding is completed, cooling is performed. At this time, the hot melt component is still in working state to keep the plastic remaining in the injection runner in a liquid state. After demolding, the sealing component re-blocks the injection runner. When producing the next product, the plastic remaining in the injection runner enters the mold cavity, reducing plastic loss.

[0014] Optionally, the lateral parting mechanism includes a parting block and a parting column. The parting block is slidably connected to the fixed mold base, and the parting column is fixed to the moving mold base. The parting block has an inclined parting hole, and the parting column can exit the parting hole and push the sealing member to move.

[0015] By adopting the above technical solution, during mold closing, the parting column pushes the parting block to move towards the center while simultaneously pushing the sealing component to move, causing the sealing component to exit the injection runner. During demolding, the parting column pushes the parting block away from the center, and the sealing component re-enters the injection runner. By using the movement of the parting column to control the opening and closing of the injection runner, the structure is ingenious and has a higher degree of automation.

[0016] Optionally, the fixed mold base is provided with an adjustment hole, which is connected to the parting hole and the sealing hole respectively. A connecting plate is rotatably connected in the adjustment hole, and the connecting plate is rotatably connected to the sealing component and the hot melt component respectively. The parting column can push the connecting plate to rotate.

[0017] By adopting the above technical solution, when the parting column extends into the adjustment hole, it contacts the connecting plate and pushes the connecting plate to rotate, causing the connecting plate to pull the sealing part out of the injection molding channel. At the same time, under the action of the connecting plate, the hot melt part starts to work. The connecting plate is used as a medium to control the sealing part and the hot melt part simultaneously, and the structure is simple.

[0018] Optionally, the sealing component includes a stop block and a connecting rod. One end of the connecting rod is connected to the stop block, and the other end of the connecting rod is rotatably connected to the connecting plate. An elastic element is sleeved on the connecting rod, and the two ends of the elastic element act on the bottom wall of the sealing hole and the stop block, respectively.

[0019] By adopting the above technical solution, when the parting column pushes the connecting plate, the elastic element contracts and the stop block exits the injection molding channel. When the parting column stops pushing the connecting plate, the elastic element returns to its initial state and the stop block returns to the injection molding channel.

[0020] Optionally, the hot melt component includes a hot melt ring and a conductive rod, one end of which is rotatably connected to the connecting plate, and the other end of which is electrically connected to the hot melt ring.

[0021] By adopting the above technical solution, when the parting column pushes the connecting plate, the hot melt ring does not contact the conductive rod and the hot melt ring is closed. When the parting column stops pushing the connecting plate, the hot melt ring is electrically connected to the conductive rod, and the hot melt ring works and heats the injection nozzle.

[0022] Optionally, the moving mold base includes a first template and a second template, the first template and the second template are detachably connected, and the first template is provided with a limiting hole for fixing the parting column.

[0023] By adopting the above technical solution, when installing the parting column, one end of the limiting column is placed in the limiting hole, and then the first template and the second template are connected to fix the parting column, so that the parting column can stably push the parting block, the sealing part and the hot melt part.

[0024] Optionally, it also includes several guide pillars, one end of which is fixed inside the moving mold base, and the other end of which can extend into the fixed mold base.

[0025] By adopting the above technical solution, the guide column can limit the moving mold base during mold closing and demolding, enabling the moving mold base to make stable linear movements and ensuring stable operation of mold closing and demolding.

[0026] Optionally, an ejector rod is connected to the moving mold base, the ejector rod passing through the moving mold base and slidably connected to the moving mold base.

[0027] By adopting the above technical solution, during demolding, the ejector rod is pushed to lift the molded product, so that the product is disengaged from the mold, making it easier to remove the product from the mold and improving production efficiency.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. This application includes a sealing element to block the injection runner. Before and after injection molding, the sealing element extends into the injection runner from the sealing hole, at which point the injection runner is closed. After preparation, the lateral parting mechanism retracts, pushing the sealing element back into the sealing hole, at which point the injection runner is open. Then, the injection molding machine quickly injects plastic into the injection runner. After cooling, the product is formed. The sealing element can block the injection runner when not in use, preventing dust from entering the mold and improving product quality.

[0030] 2. This application controls the working state of the hot melt component and the sealing component through lateral parting. Before injection molding, the sealing component blocks the injection runner to prevent dust from entering. During injection molding, the sealing component exits the injection runner, and the injection molding machine injects plastic into the injection runner. The hot melt component begins to heat the injection nozzle to ensure a stable plastic flow rate. After injection molding is completed, the hot melt component is cooled. At this time, the hot melt component is still in working state to keep the plastic remaining in the injection runner in a liquid state. After demolding, the sealing component re-blocks the injection runner. When producing the next product, the plastic remaining in the injection runner enters the mold cavity, reducing plastic loss.

[0031] 3. This application uses a parting column to push the hot melt part and the sealing part, and uses a connecting plate as a transmission medium. When the mold is closed, the parting column pushes the parting block to move towards the center and pushes the sealing part to move, so that the sealing part exits the injection runner. When the mold is demolded, the parting column pushes the parting block away from the center and the sealing part re-enters the injection runner. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0042] A refrigerator drawer injection mold, as shown in the reference. Figure 1 and Figure 2 It includes a moving mold base 1, a fixed mold base 2, an injection nozzle 3, and a side parting mechanism 4. The moving mold base 1 and the fixed mold base 2 are slidably connected. The side parting mechanism 4 is slidably connected to the moving mold base 1. The injection nozzle 3 is placed on the fixed mold base 2. Figure 3 The injection nozzle 3 has an injection channel 31 for injecting glue.

[0043] Reference Figure 1 and Figure 4 The fixed mold base 2 includes a first fixed plate 22, a second fixed plate 23 and a center block 24. The first fixed plate 22 and the second fixed plate 23 are detachably connected by bolts. The first fixed plate 22 has a first stepped hole 221 and the second fixed plate 23 has a second stepped hole 231. When the first fixed plate 22 and the second fixed plate 23 are connected, the first stepped hole 221 and the second stepped hole 231 communicate with each other.

[0044] The injection nozzle 3 is fixed in the first step hole 221, and the center block 24 is fixed in the second step hole 231. The injection nozzle 3 abuts against the center block 24. The center block 24 has a cavity 241 for molding products. The cavity 241 is connected to the injection flow channel 31. When the injection molding machine injects plastic, the plastic enters the cavity 241 from the injection flow channel 31.

[0045] Reference Figure 2 and Figure 4 The lateral parting mechanism 4 includes a parting block 41 and a parting column 42. The parting block 41 is slidably connected to the fixed mold base 2, and the parting column 42 is fixed on the moving mold base 1. The parting block 41 has a parting hole 411 at an angle. When the moving mold base 1 slides towards the fixed mold base 2, the parting column 42 extends into the parting hole 411 and pushes the parting block 41 towards the center block 24. When the moving mold base 1 slides away from the fixed mold base 2, the parting column 42 is gradually pulled out from the parting hole 411 and pushes the parting block 41 away from the center block 24.

[0046] Reference Figure 5 and Figure 6 The lateral parting mechanism 4 consists of two sets, which are arranged opposite to the moving mold base 1. There are multiple parting columns 42, and parting holes 411 are arranged one-to-one with the parting columns 42. In this embodiment, there are two parting columns 42, and correspondingly, there are also two parting holes 411. In other embodiments, there may be more than two parting columns 42 to improve the stability of the parting columns 42 pushing the parting block 41.

[0047] To improve the stability of the sliding of the parting block 41, in this embodiment, a connecting rod 43 is provided between the parting block 41 and the center block 24. There are two connecting rods 43, one end of which is fixedly connected to the parting block 41, and the other end of which is inserted into the center block 24. The movement of the parting block 41 is constrained by the connecting rods 43. In another embodiment, a protrusion can also be connected to the side of the parting block 41 near the second fixing plate 23. A T-slot is provided on the second fixing plate 23. The connecting protrusion is placed in the T-slot and slides along the opening direction of the T-slot. In other embodiments, the connecting rod 43 and the connecting protrusion can also be provided simultaneously.

[0048] It should be noted that constraining the movement of the parting block 41 by connecting the bumps is a relatively mature existing technology, which is not shown in the figure.

[0049] Reference Figure 3 and Figure 5An elastic element 8 is provided between the parting block 41 and the center block 24. One end of the elastic element 8 is connected to the side wall of the parting block 41, and the other end of the elastic element 8 is connected to the side wall of the center block 24. When demolding, that is, after the parting column 42 is pulled out from the parting hole 411, the elastic element 8 prevents the parting block 41 from moving closer to the center block 24, reducing the possibility of obstruction in the operation of the lateral parting mechanism 4.

[0050] Reference Figure 6 and Figure 7 The moving mold base 1 includes a first template 11 and a second template 12. The first template 11 and the second template 12 are detachably connected. The first template 11 is provided with a limiting hole 111 for fixing the parting column 42. Specifically, the limiting hole 111 is stepped. One end of the parting column 42 placed in the moving mold base 1 is correspondingly stepped and has a tapered end. When the first template 11 is connected to the second template 12, the tapered end abuts against the second template 12.

[0051] Furthermore, the moving mold base 1 also includes a third template 13 and a mating block 14. The third template 13 is slidably connected to the first template 11, and the mating block 14 is detachably connected to the third template 13. The third template 13 has a third step hole 131 in the center that matches the mating block 14. When the mold is closed, the moving mold base 1 abuts against the fixed mold base 2, the mating block 14 enters the cavity 241, and the center block 24 combines with the mating block 14 to form a cavity for producing a refrigerator drawer.

[0052] The third template 13 has a through hole 132 that matches the parting column 42. The parting column 42 passes through the through hole 132 and exits a certain distance. The length of the exited part is specifically set according to the distance that the parting block 41 needs to slide. In this embodiment, the part of the parting column 42 that exits through the through hole 132 is two-fifths of its overall length.

[0053] Reference Figure 2 and Figure 6 An ejector rod 10 is connected to the mating block 14. The ejector rod 10 passes through the mating block 14 and is slidably connected to the mating block 14. When demolding, the ejector rod 10 is pushed to lift the molded product from the mating block 14. After the relevant personnel remove the product, the production of the next product can proceed. There are multiple ejector rods 10. In this embodiment, there are two ejector rods 10. In other embodiments, there can be more than two ejector rods 10 to further increase the contact area between the ejector rod 10 and the molded product when it lifts the product.

[0054] Furthermore, in order to reduce the possibility of breakage when the ejector rod 10 lifts the product, in this embodiment, the end of the ejector rod 10 that can contact the product can be set in a stepped shape to increase the contact area between the ejector rod 10 and the product. The end of the ejector rod 10 away from the product can be connected to a synchronous plate. By pushing the synchronous plate, multiple synchronous plates can move synchronously.

[0055] Reference Figure 6 and Figure 8 It also includes several guide pillars 9. In this embodiment, there are four guide pillars 9, which are evenly arranged around the moving mold base 1. One end of the guide pillar 9 is fixed in the moving mold base 1, and the other end of the guide pillar 9 can extend into the fixed mold base 2. Specifically, the first template 11 is provided with a fourth step hole 112. The end of the guide pillar 9 placed in the moving mold base 1 is arranged in a step shape. The other end of the guide pillar 9 passes through the third template 13 and exits a certain distance. When the mold is closed, the part of the guide pillar 9 that exits the third template 13 enters the fixed mold base 2.

[0056] Reference Figure 6 and Figure 8 The fixed mold base 2 is provided with several push rods 20. The push rods 20 pass through the third template 13, the first template 11 and the second template 12 in sequence. One end of the push rod 20 is set in a stepped shape. The third template 13 is provided with a fifth step hole 133 that matches the push rod 20. The other end of the push rod 20 is fitted with an elastic element 8. The two ends of the elastic element 8 act on the third template 13 and the second template 12 respectively.

[0057] During mold closing, the third template 13 abuts against the second fixed plate 23 and the first template 11 respectively. At this time, the push rod 20 extends into the second fixed plate 23, and the elastic element 8 contracts. During demolding, it pushes the third template 13 to slide. At this time, the elastic element 8 rebounds, so that the first template 11 and the third template 13 maintain a distance and abut against the second fixed plate 23. The cavity does not change. Then, the push rod 20 abuts against the stepped fifth step hole 133 and drives the third template 13 away from the second fixed plate 23. The cavity disintegrates and the product is exposed.

[0058] Reference Figure 2 and Figure 3 The injection nozzle 3 has two sealing holes 32 symmetrically arranged relative to the injection flow channel 31. The sealing holes 32 are connected to the injection flow channel 31. The sealing holes 32 are provided with sealing elements 5 for sealing the injection flow channel 31. Furthermore, the injection nozzle 3 is also provided with a hot melt element 6 for heating the injection nozzle 3. The injection nozzle 3 has an outlet hole 33 for accommodating the hot melt element 6. The hot melt element 6 is placed in the outlet hole 33.

[0059] The lateral parting mechanism 4 can drive the sealing member 5 to extend into or out of the injection runner 31, and can also control the opening and closing of the hot melt 6. When the sealing member extends into the injection runner 31, the hot melt 6 is in a closed state, and when the sealing member 5 exits the injection runner 31, the hot melt 6 is in a working state.

[0060] Specifically, the lateral parting mechanism 4 synchronously controls the sealing component 5 and the hot melt component 6 through the connecting plate 7. The first fixed plate 22 has an adjustment hole 21. The connecting plate 7 is rotatably connected in the adjustment hole 21. The sealing component 5 and the hot melt component 6 both extend into the adjustment hole 21 and are rotatably connected to the connecting plate 7. When the parting column 42 exits the parting hole 411, it can extend into the adjustment hole 21 and push the connecting plate 7 to rotate, thereby causing the hot melt component 6 and the sealing component 5 to slide relative to the injection nozzle 3.

[0061] To prevent interference when the hot melt component 6 and the sealing component 5 slide relative to the injection nozzle 3, a groove is provided on the connecting plate 7, and the parts of the hot melt component 6 and the sealing component 5 that are rotatably connected to the connecting plate 7 can slide along the opening direction of the groove.

[0062] The sealing component 5 includes a stop block 51 and a connecting rod 52. One end of the connecting rod 52 is connected to the stop block 51, and the other end of the connecting rod 52 is rotatably connected to the connecting plate 7. After the mold is closed, the two stop blocks 51 abut against each other to block the injection runner 31. The stop block 51 is provided with a protective groove 511. The protective grooves 511 on the two stop blocks 51 are combined to form a conical protective surface, which matches the shape of the injection end of the injection molding machine, so as to avoid damaging the injection end when the injection molding machine extends into the injection runner 31 before the mold is closed.

[0063] An elastic element 8 is sleeved on the connecting rod 52. The two ends of the elastic element 8 act on the bottom wall of the sealing hole 32 and the stop block 51, respectively. In this embodiment, all the elastic elements 8 are springs. When the parting column 42 exits the adjustment hole 21, the parting column 42 no longer contacts the connecting plate 7. At this time, the contracted spring pushes the stop block 51, so that the stop block 51 re-seals the injection channel 31.

[0064] The hot melt component 6 includes a hot melt ring 61 and a conductive rod 62. The hot melt ring 61 is arranged in a ring shape and placed in a guide groove. The guide groove is not connected to the injection flow channel 31 to reduce the impact of the fluid plastic on the hot melt ring 61. One end of the conductive rod 62 is rotatably connected to the connecting plate 7, and the other end of the conductive rod 62 can be electrically connected to the hot melt ring 61. When the parting column 42 is not in contact with the connecting plate 7, the guide rod and the hot melt ring 61 maintain a distance, and the hot melt ring 61 is not energized, that is, it is in a closed state. When the parting column 42 pushes the connecting plate 7 to rotate, the conductive rod 62 gradually approaches the hot melt ring 61 and eventually becomes electrically connected to the hot melt ring 61. At this time, the hot melt ring 61 is in the working state.

[0065] The implementation principle of this application embodiment is as follows: Before injection molding, the stop block 51 extends into the injection runner 31 to block the injection runner 31 and prevent dust from entering. During injection molding, the mold is closed. During the mold closing process, the parting column 42 extends into the parting hole 411 and pushes the parting column 42 closer to the center block 24. Then, it partially exits the parting hole 411 and contacts the connecting plate 7, pushing the connecting plate 7 to rotate. The connecting plate 7 pulls the connecting rod 52, causing the stop block 51 to exit the injection runner 31. The injection molding machine injects plastic into the injection runner 31. The connecting plate 7 pulls the connecting rod 52, causing the stop block 51 to exit the injection runner 31. During the process of connecting rod 52, conductive rod 62 is also pushed, causing conductive rod 62 to move closer to hot melt ring 61 and eventually connect electrically with hot melt ring 61. Hot melt ring 61 begins to heat the surrounding area of ​​injection nozzle 3 where injection flow channel 31 is opened, ensuring stable plastic flow rate. After injection is completed, cooling is performed. At this time, hot melt part 6 is still in working state, keeping the plastic remaining in injection flow channel 31 in a liquid state. After demolding, stop block 51 re-seals injection flow channel 31. When producing the next product, the plastic remaining in injection flow channel 31 enters the mold cavity.

[0066] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
