A household plastic product forming mold

Abstract

The present invention belongs to the technical field of forming molds, and specifically is a household plastic product forming mold, comprising a lower mold, a guide rod and an upper mold, wherein the lower mold and the upper mold are arranged relatively relatively. When the mold core needs to be replaced, the control handle can be rotated so that the mold core is separated from the inner wall of the lower mold, thereby facilitating the replacement of the mold core, avoiding the problem that when replacing the traditional mold core, the entire mold needs to be disassembled, and then the bolts connecting the mold core and the lower mold need to be removed one by one before the entire mold core can be disassembled, which is a relatively troublesome problem. At the same time, when installing and disassembling the traditional mold core, the operator needs to contact the inner wall of the mold core in order to place the mold core to the corresponding position, thereby affecting the problem of product quality in the subsequent processing process. The present invention facilitates the installation and disassembly of the mold core, and at the same time reduces the number of contacts with the inner wall of the mold core during installation and disassembly, thereby improving the quality of the product in the subsequent processing process.

[0002] In the production process of modern household plastic products, molding molds play a vital role. With the growing demand for plastic products and the increasing requirements for product quality and diversity, mold technology is also facing many challenges and changes.

[0003] After searching, such as the Chinese patent mold (CN202411143587.1), the invention discloses a mold, including a front mold and a rear mold, the front mold includes a front mold assembly plate, a front mold core and an oblique drawer module, the front mold core and the oblique drawer module are both mounted on the front mold assembly plate; the rear mold includes a rear mold assembly plate, a rear mold core, a slide module, an oblique ejector module and an ejection mechanism, the rear mold core and the slide module are both mounted on the rear mold assembly plate, the rear mold assembly plate is provided with a through cavity, the ejection mechanism includes an ejector plate assembly, a plurality of guide rods, a plurality of first elastic members, a plurality of ejector pins that can be grinded And multiple garbage pins are used to adjust the stroke of the ejector pin, the two ends of the guide rod are respectively connected to the inner walls of the two sides of the through cavity, the ejector plate assembly is slidably installed on the guide rod, one end of the first elastic member is connected to a side of the ejector plate assembly close to the rear mold core, and the other end is connected to the inner wall of the through cavity, one end of the inclined ejector module and the ejector pin are connected to the ejector plate assembly, and the other ends pass through the rear mold plate and the rear mold core in turn, and multiple garbage pins can be detachably installed on the side of the ejector plate assembly away from the rear mold core. Although the installation and disassembly of the mold core is realized, some problems still exist.

[0004] In the field of manufacturing household plastic products, the use of molds is extremely common. The traditional molding mold structure has many inconveniences in the replacement operation of the mold core. In previous mold designs, the mold core is usually tightly fixed to the lower mold by bolts. When the mold core needs to be replaced, the entire mold must first be removed from the production equipment. This process itself is relatively cumbersome and time-consuming. Subsequently, the operator is required to use tools to loosen and remove the numerous bolts connecting the mold core and the lower mold one by one. In the process of removing the bolts, not only is the workload large, but the bolts may be rusty or too tightly tightened, which will further increase the difficulty and time cost of disassembly.

[0005] In addition, during the installation of traditional mold cores, operators often need to manually support and adjust the position of the mold core in order to accurately place the mold core to the corresponding position inside the lower mold, which will inevitably cause contact with the inner wall of the mold core. In the molding process of household plastic products, the quality requirements for products are increasing. Even tiny stains, grease or other impurities on the hands of operators may be transferred to the plastic products in the subsequent injection molding process after contacting the inner wall of the mold core, resulting in defects and spots on the product surface and even affecting the dimensional accuracy and physical properties of the product, reducing the product's qualification rate and quality stability.

[0006] Therefore, a kind of household plastic product forming die is proposed for the problems referred to above. Summary of the invention

[0018] Beneficial effects of the present invention:

[0019] 1. The present invention provides a household plastic product forming mold, which can rotate a control handle when the mold core needs to be replaced. The rotation of the control handle drives the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the threaded rod to rotate, and the rotation of the threaded rod drives the threaded block to move upward, thereby driving the bracket to move upward, and the upward movement of the bracket drives the mold core to move upward, so that the mold core is separated from the inner wall of the lower mold, thereby facilitating the replacement of the mold core, avoiding the need to disassemble the entire mold when replacing the traditional mold core, and then disassemble the bolts connecting the mold core and the lower mold one by one before disassembling the entire mold core, which is a more troublesome problem. At the same time, when installing and disassembling the traditional mold core, the operator needs to contact the inner wall of the mold core in order to place the mold core to the corresponding position, thereby affecting the problem of product quality in the subsequent processing process. The installation and disassembly of the mold core is convenient, and the number of contacts with the inner wall of the mold core during installation and disassembly is reduced, thereby improving the quality of the product in the subsequent processing process;

[0020] Second, the present invention provides a household plastic product forming mold, which can fix the mold core after installing it through the setting of the fixing mechanism, thereby avoiding the problem that the mold core is separated from the inner wall of the lower mold during use, improving the stability and reliability of the device, and at the same time, when the mold core is disassembled, the mold core can be automatically released, thereby facilitating the removal of the mold core from the inner wall of the lower mold;

[0021] 3. The present invention provides a household plastic product forming mold. Through the control mechanism set up, when the control handle drives the threaded block to move upward, the threaded block will push the rotating plate, so that the rotating plate rotates around the second rotating rod. During the rotation of the rotating plate, the rack plate will pull the rack plate to slide on the inner wall of the third slide groove. While the rack plate slides, it will drive the first gear to rotate. The rotation of the first gear drives the ball valve to rotate, thereby controlling the ball valve to open and close the coolant inlet pipe. During the upward movement of the threaded block, the ball valve will be controlled to open, thereby realizing cooling of the lower mold, avoiding the problem that when the mold core and the lower mold are disassembled, the mold core is difficult to detach from the inner wall of the lower mold due to the high temperature of the mold core and the lower mold, and the effect of thermal expansion and contraction, which facilitates the disassembly of the mold core and reduces the wear between the mold core and the lower mold.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Specific examples are given below.

[0034] See also Figure 1-Figure 7 The present invention provides a household plastic product forming mold, comprising a lower mold 1, a guide rod 29 and an upper mold 30. The lower mold 1 and the upper mold 30 are arranged opposite to each other, and the lower mold 1 and the upper mold 30 are connected by the guide rod 29. A control handle 2 is arranged on one side of the lower mold 1. The end of the control handle 2 passes through the lower mold 1 and is fixedly installed with a first rotating rod 5. A first bevel gear 6 is fixedly installed on the outer wall of the first rotating rod 5. A second bevel gear 7 is meshedly connected to one side of the first bevel gear 6. A threaded rod 8 is fixedly installed on the side of the second bevel gear 7 away from the first bevel gear 6. The two ends of the threaded rod 8 are respectively embedded in the inner wall of the lower mold 1 and are rotatably connected to the inner wall of the lower mold 1. The outer wall of the threaded rod 8 is threadedly sleeved with a threaded block 9. A bracket 10 is fixedly installed at one end of the threaded block 9 away from the threaded rod 8. Vertical rods 11 are fixedly installed on both sides of the bracket 10. The vertical rods 11 are embedded in the inner wall of the second slide groove 31. The second slide groove 31 is opened on the side wall of the mold core 3. The mold core 3 is embedded in the inner wall of the lower mold 1. The vertical rod 11 is connected to the block 12 by a fixing mechanism. A control mechanism for controlling the cooling system switch is provided on one side of the threaded block 9.

[0035] When the mold core 3 needs to be replaced, the control handle 2 can be rotated. The rotation of the control handle 2 will drive the first bevel gear 6 to rotate, and the rotation of the first bevel gear 6 will drive the second bevel gear 7 to rotate. The rotation of the second bevel gear 7 will drive the threaded rod 8 to rotate, and the rotation of the threaded rod 8 will drive the threaded block 9 to move upward, thereby driving the bracket 10 to move upward, and the upward movement of the bracket 10 drives the mold core 3 to move upward, so that the mold core 3 is separated from the inner wall of the lower mold 1, so as to facilitate the replacement of the mold core 3, avoiding the need to disassemble the entire mold when replacing the traditional mold core 3, and then remove the bolts connecting the mold core 3 and the lower mold 1 one by one before the entire mold core 3 can be disassembled, which is a more troublesome problem. At the same time, when installing and disassembling the traditional mold core 3, the operator needs to contact the inner wall of the mold core 3 in order to place the mold core 3 to the corresponding position, thereby affecting the problem of product quality in the subsequent processing process. The installation and disassembly of the mold core 3 is convenient, and the number of contacts with the inner wall of the mold core 3 during installation and disassembly is reduced, thereby improving the quality of the product in the subsequent processing process.

[0036] See also Figure 3-Figure 7 In the figure, the fixing mechanism includes a slot 19 opened on the side wall of the second slide groove 31, and the inner wall of the slot 19 is clamped with a block 12, and the block 12 is slidably installed on the side wall of the vertical rod 11. The first limit plates 14 are fixedly installed on both sides of the block 12, and the first limit plates 14 are connected to the inner wall of the vertical rod 11 through a first spring 13. The end of the block 12 away from the slot 19 is in contact with the side wall of the push rod 15, and the push rod 15 passes through the vertical rod 11 and abuts against the inner wall of the lower mold 1. The outer wall of the push rod 15 is fixedly installed with a second limit plate 17, and the second limit plate 17 is connected to the inner wall of the vertical rod 11 through a second spring 18.

[0037] By setting up the fixing mechanism, the mold core 3 can be fixed after the mold core 3 is installed, thereby avoiding the problem of the mold core 3 being separated from the inner wall of the lower mold 1 during use, improving the stability and reliability of the device. At the same time, when the mold core 3 is disassembled, the mold core 3 can be automatically released, thereby facilitating the removal of the mold core 3 from the inner wall of the lower mold 1.

[0038] See also Figure 3-Figure 7 In the figure, a limiting groove 16 is provided on the side wall of the push rod 15, and the lower groove wall of the limiting groove 16 is set to be inclined. When the push rod 15 moves, the limiting groove 16 will push the block 12 to move, thereby controlling the block 12 to be embedded in the inner wall of the slot 19, so that after the mold core 3 is embedded in the lower mold 1, the mold core 3 and the vertical rod 11 are automatically connected together, thereby fixing the mold core 3.

[0039] See also Figure 7, the control mechanism in the figure includes a rotating plate 27 arranged above the threaded block 9, and the two sides of the rotating plate 27 are rotatably connected to the inner wall of the lower mold 1 through the second rotating rod 28, and the second rotating rod 28 is fixedly installed on the two sides of the rotating plate 27. A first slide groove 26 is opened on the side of the rotating plate 27 away from the threaded block 9, and a second connecting rod 25 is installed on the inner wall of the first slide groove 26. One end of the second connecting rod 25 away from the first slide groove 26 is fixedly installed on the end of the rack plate 24, and the rack plate 24 is slidably installed on the inner wall of the third slide groove 32. The third slide groove 32 is opened on the inner wall of the lower mold 1, and the rack plate 24 and the inner wall of the third slide groove 32 are connected by a third spring. A first gear 23 is meshed and installed on one side of the rack plate 24, and a first connecting rod 22 is fixedly installed on the inner wall of the first gear 23. The top end of the first connecting rod 22 passes through the coolant inlet pipe 4 and is embedded in the inner wall of the coolant inlet pipe 4. The coolant inlet pipe 4 is arranged on one side of the lower mold 1, and a ball valve 21 is fixedly installed on the top end of the first connecting rod 22.

[0040] By means of the control mechanism, in the process of controlling the handle 2 to drive the threaded block 9 to move upward, the threaded block 9 will push the rotating plate 27, so that the rotating plate 27 rotates around the second rotating rod 28. In the process of rotating the rotating plate 27, the rack plate 24 will be pulled to slide on the inner wall of the third slide groove 32. While the rack plate 24 slides, it will drive the first gear 23 to rotate. The rotation of the first gear 23 drives the ball valve 21 to rotate, thereby controlling the ball valve 21 to open and close the coolant inlet pipe 4. In the process of the threaded block 9 moving upward, the ball valve 21 will be controlled to open, thereby realizing cooling of the lower mold 1, avoiding the problem that when the mold core 3 and the lower mold 1 are disassembled, the mold core 3 is difficult to detach from the inner wall of the lower mold 1 due to the high temperature of the mold core 3 and the lower mold 1, and the effect of thermal expansion and contraction, which facilitates the disassembly of the mold core 3 and reduces the wear between the mold core 3 and the lower mold 1.

[0041] See also Figure 5-Figure 7 In the figure, a cooling pipe 20 is fixedly installed at the end of the coolant inlet pipe 4, and the cooling pipe 20 is distributed in a U-shaped manner on the inner wall of the lower mold 1. After the coolant is passed into the coolant inlet pipe 4, the coolant is discharged from another coolant inlet pipe 4 through the cooling pipe 20. At this time, the coolant will cool the mold core 3 and the lower mold 1 at all positions, thereby improving the cooling effect of the device.

[0042] See also Figure 7 In the figure, the rotating plate 27, the rack plate 24 and the first gear 23 are all on the same horizontal plane. When the threaded block 9 is not in contact with the rotating plate 27, the rotating plate 27, under the action of the third spring, will make the rotating plate 27, the rack plate 24 and the first gear 23 all in a horizontal state, thereby ensuring that the initial state remains unchanged. Each time the threaded block 9 moves up and down, it can drive the ball valve 21 to open and close.

[0043] See also Figure 6-Figure 7 In the figure, the side of the card block 12 close to the card slot 19 is set to be inclined, and the side of the card block 12 away from the card slot 19 is set to the same size as the inner wall of the card slot 19, so that the card block 12 can be embedded in the card slot 19 more conveniently during the embedding process, avoiding the embedding process. Since the card block 12 moves upward and toward the card slot 19 at the same time, the card block 12 is embedded in the inner wall of the card slot 19 more smoothly. At the same time, when the card block 12 is completely embedded in the inner wall of the card slot 19, since the card block 12 is the same size as the card slot 19, the card block 12 can only be embedded in the inner wall of the card slot 19 and cannot move on the inner wall of the card slot 19, thereby achieving the fixation of the mold core 3 to the inner wall of the lower mold 1.

[0044] The length between the top and the bottom of the vertical rod 11 is greater than the minimum length between the top of the bracket 10 and the top of the lower mold 1. When installing and disassembling the mold core 3, the vertical rod 11 can extend out of the inner wall of the lower mold 1, so that the operator can directly contact the outer wall of the mold core 3, thereby embedding the mold core 3 between the vertical rods 11, reducing the number of times the operator contacts the inner wall of the mold core 3, thereby improving the quality of the product during the product processing process.

[0045] The length between the two sides of the block 12 is equal to the maximum length from the side wall of the limiting groove 16 to the outer wall of the vertical rod 11. When the block 12 contacts the inner wall of the top of the limiting groove 16, the block 12 is completely placed on the inner wall of the vertical rod 11, thereby avoiding the problem that the block 12 will block the mold core 3 when it is installed on the side wall of the vertical rod 11, resulting in the problem that the installation cannot be carried out.

[0046] The size of the bracket 10 is equal to the size of the bottom end of the mold core 3, so that the bracket 10 can support the mold core 3, so when the mold core 3 is installed or disassembled, it is only necessary to move and fix the bracket 10.

[0047] Working principle: When the mold core 3 needs to be installed, first turn the control handle 2. The control handle 2 drives the first rotating rod 5 to rotate. The first rotating rod 5 drives the first bevel gear 6 to rotate. The first bevel gear 6 drives the second bevel gear 7 to rotate. The second bevel gear 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the threaded block 9 to move. The threaded block 9 moves and drives the bracket 10 and the vertical rod 11 to move until the vertical rod 11 extends out of the inner wall of the lower mold 1. Then align the mold core 3 with the vertical rod. 11, so that the vertical rod 11 is embedded in the inner wall of the second slide groove 31, and then the mold core 3 is pushed until the mold core 3 abuts against the bracket 10, and then the above operation is repeated to embed the vertical rod 11 into the inner wall of the lower mold 1. When the bracket 10 is in the process of fitting with the inner wall of the lower mold 1, the push rod 15 will be squeezed to make the push rod 15 move. The movement of the push rod 15 will drive the block 12 to move on the side wall of the limiting groove 16. The movement of the limiting groove 16 will push the block 12 to move. At this time, the block 12 will be embedded in the inner wall of the card groove 19. Until the bracket 10 abuts against the inner wall of the lower mold 1, the clamping block 12 is completely embedded in the inner wall of the clamping groove 19, thereby fixing the mold core 3. During the movement of the threaded block 9, the threaded block 9 will squeeze the rotating plate 27, so that the rotating plate 27 rotates around the second rotating rod 28. During the rotation of the rotating plate 27, the second connecting rod 25 will be pulled to move, and the movement of the second connecting rod 25 will pull the rack plate 24 to move. The movement of the rack plate 24 will drive the first gear 23 to rotate, and the rotation of the first gear 23 will drive the ball valve 21 to rotate, thereby controlling the switch of the coolant inlet pipe 4, so that the coolant in the coolant inlet pipe 4 enters from the coolant inlet pipe 4, then enters the inner wall of the cooling pipe 20, and finally is discharged from the other coolant inlet pipe 4, thereby cooling the entire lower mold 1. When the threaded block 9 continues to move, the distance of the rotating plate 27 is insufficient. Under the action of the third spring, the rotating plate 27 will be driven to return to the initial position, thereby preparing for the next movement of the threaded block 9.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
