Technical Field

[0001] The invention relates to the technical field of plastic product injection molding, in particular to a plastic product injection molding device. Background Art

[0002] Injection molding equipment, commonly known as injection molding machine, is a mechanical device used to manufacture plastic products. It heats the plastic material (usually granular or powdered plastic resin) to a molten state and then injects it into the cavity of a closed mold. After cooling and solidification, the desired plastic product is formed. Injection molding is an efficient and highly automated production method that is widely used in the manufacture of various plastic parts and products.

[0003] In the prior art, after injection molding is completed, the product needs to be removed from the mold for subsequent processing or packaging. This step is a key link in the injection molding production process, but it is also a place where problems are prone to occur. The product may be deformed during the removal process due to various reasons. For example, when the ejector or robot is removing the product, if the force is not properly controlled or the operation is not precise, it may apply uneven force to the product, causing deformation and affecting product quality. Summary of the invention

[0004] The object of the present invention is to provide a plastic product injection molding device to solve at least one technical problem existing in the above-mentioned prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a plastic product injection molding device, comprising a driving assembly slidably connected to a bracket through a base, and further comprising:

[0006] An injection molding assembly mounted above the drive assembly for injection molding;

[0007] A clamping part installed at the bottom of the injection molding component, a control console is installed on one side of the clamping part, and when the control console is triggered, the operation of the injection molding component and the driving component can be controlled;

[0008] The demoulding component comprises a supporting component fixedly mounted on a bracket, an extrusion component movably mounted on the supporting component, a pushing component for demoulding mounted on one end of the extrusion component, and a linkage component for cooling mounted on the pushing component.

[0009] Preferably, the bracket includes three groups of baffles fixedly mounted on the top of the base, frames are mounted on the four corners of the three groups of baffles, and the three groups of baffles are mounted at intervals on the top of the base, support rods are fixedly mounted on the sides of the baffles, one side of the support rod is hinged with a hinge rod, one end of the hinge rod away from the support rod is rotatably connected to a hinge rod 2 via an axis, and one end of the hinge rod 2 is mounted on the opposite side of the other group of baffles via a connecting seat.

[0010] Preferably, a cylinder is movably connected at the hinge of the articulated rod 1 and the articulated rod 2. When the cylinder is running, the two ends of the articulated rod in contact with each other are driven to descend into a "V" shape, driving a group of baffles to be slidably connected to the frame.

[0011] Preferably, the injection molding assembly is fixedly mounted on an injection molding rod on the frame, a cylinder for driving the injection molding rod is mounted on the top of the injection molding rod, and a filling device for injection molding is mounted on the cylinder.

[0012] Preferably, the support assembly includes a mounting block fixedly mounted on a middle group of the three groups of baffles, and a mounting shell fixedly mounted on one side of the mounting block, and the mounting shell is used for limiting position.

[0013] Preferably, the extrusion assembly comprises an outer shell slidably connected to the mounting shell, a guide block is fixedly mounted on one side of the outer shell, and a limit block is also fixedly mounted in the outer shell.

[0014] Preferably, the pushing assembly includes a spring 1 fixedly mounted inside the shell, a push rod being fixedly mounted on one end of the spring 1, an inclined groove being provided on the push rod, a limiting rod being slidably connected in the inclined groove, and both ends of the limiting rod being in contact with the side walls of the limiting block.

[0015] Preferably, the linkage assembly includes a groove provided on the mold clamping member, the guide block is slidably connected in the groove, a push block is fixedly mounted on the end of the guide block, and the shape of the push block is the same as that of the model.

[0017] Preferably, the push block is in contact with the edge of the mold assembly, and the push block is arranged on the upper half of the mold assembly.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the push component pushes the mold to be demoulded at the upper edge of the mold, the mold will be slightly tilted, which is convenient for the operator to remove it. At the same time, a gap will be generated between the side of the mold and the mold parts, so that the cold air can enter from the top to reduce the temperature of the mold and the product more quickly. Because the density of cold air is greater than that of hot air, it will sink naturally. This can accelerate the cooling speed of the product, shorten the molding cycle, and improve production efficiency. At the same time, due to the friction between the surface of the product and the surface of the mold, white or bright spots will appear on the surface of the product. The cold air entering from the top helps to reduce the temperature difference between the product and the mold, thereby reducing the occurrence of the white top phenomenon. By optimizing the cooling process, this molding equipment can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0020] Second, by connecting hinged rod 1 and hinged rod 2, the length of the lever arm can be increased, so as to obtain a greater torque under the same cylinder thrust, making it easier to move heavy objects. The connection between hinged rods 1 and 2 can provide a certain degree of elasticity and buffering, reducing the impact and vibration that may be generated when the cylinder is pulled directly, and protecting the moved baffle and the cylinder itself.

DETAILED DESCRIPTION

[0031] 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.

[0032] Embodiment 1;

[0033] See also Figures 1 to 9 The present invention provides a technical solution: a plastic product injection molding device, comprising a driving component 3 slidably connected to a bracket 2 through a base 1, and further comprising:

[0034] An injection molding assembly 4 installed above the driving assembly 3 for injection molding;

[0035] A clamping part 5 is installed at the bottom of the injection molding component 4, and a control console 6 is installed on one side of the clamping part 5. When the control console 6 is triggered, it can control the operation of the injection molding component 4 and the driving component 3;

[0036] The demoulding component 7 includes a supporting assembly 8 fixedly mounted on the bracket 2, an extrusion assembly 9 movably mounted on the supporting assembly 8, a pushing assembly 10 for demoulding mounted at one end of the extrusion assembly 9, and a linkage assembly 11 for cooling mounted on the pushing assembly 10.

[0037] When the device is injecting the mold, the operator uses the control console 6 to drive the component 3 to tightly close the two combined molds 5, and then uses the injection component 4 to perform injection molding on the top of the mold clamping part 5. After the injection molding is completed, the mold clamping part 5 is opened. When the mold is opened, the extrusion component 9 and the pushing component 10 cooperate with each other to push the mold to be demolded at the upper edge of the mold, and cold air enters from the upper end of the mold clamping part 5 to cool the mold.

[0038] When the push component 10 pushes the mold to be demolded at the upper edge of the mold, the mold after injection molding will be slightly tilted, which is convenient for the operator to remove it. At the same time, a gap is generated between the side of the mold and the clamping part 5, so that the cold air entering from the upper end can reduce the temperature of the mold and the product more quickly, because the density of cold air is greater than that of hot air, and it will sink naturally. This can accelerate the cooling speed of the product, shorten the molding cycle, and improve production efficiency. At the same time, due to the friction between the surface of the product and the surface of the mold, white or bright spots appear on the surface of the product. The cold air entering from the upper end helps to reduce the temperature difference between the product and the mold, thereby reducing the occurrence of the white top phenomenon. By optimizing the cooling process, the device can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0039] Embodiment 2 improves the specific process of injection molding based on embodiment 1. For specific methods, please refer to Figures 1-2 ;

[0040] Furthermore, the bracket 2 includes three groups of baffles 12 fixedly mounted on the top of the base 1, a frame 13 is mounted on the four corners of the three groups of baffles 12, and the three groups of baffles 12 are installed at intervals on the top of the base 1, a support rod 14 is fixedly mounted on the side of the baffle 12, a hinged rod 15 is hinged on one side of the support rod 14, one end of the hinged rod away from the support rod 14 is connected to a hinged rod 2 16 via an axis rotation, and one end of the hinged rod 2 16 is installed on the opposite side of another group of baffles 12 via a connecting seat.

[0041] Furthermore, a cylinder 17 is movably connected to the hinge of the articulated rod 15 and the articulated rod 2 16. When the cylinder 17 is running, the two ends of the articulated rod 15 and the articulated rod 2 16 that are in contact with each other are driven to descend into a "V" shape, driving a group of baffles 12 to be slidably connected to the frame 13.

[0042] When the operator controls the driving shaft on the cylinder 17 to descend, the two ends of the articulated rod 15 and the articulated rod 2 16 that are in contact with each other are driven to descend into a "V" shape, thereby driving a group of baffles 12 to be slidably connected to the frame 13. Since the mold assembly 5 is fixedly installed on the side of the baffle 12 opposite to the control console 6, the two combined modules 5 can be merged or separated under the drive of the cylinder 17.

[0043] It should be noted that, by connecting the articulated rod 15 and the articulated rod 2 16, the length of the lever arm can be increased, thereby obtaining a greater torque under the same thrust of the cylinder 17, making it easier to move heavy objects, and the connection between the articulated rods 15 and 16 can provide a certain degree of elasticity and buffering, reducing the impact and vibration that may be generated when the cylinder 17 is pulled directly, thereby protecting the moved baffle 12 and the cylinder 17 itself.

[0044] Furthermore, the injection molding assembly 4 is fixedly mounted on an injection molding rod 18 on the frame 13, a cylinder 19 for driving the injection molding rod 18 is mounted on the top of the injection molding rod 18, and a filling device 20 for injection molding is mounted on the cylinder 19. When the two combined modules 5 are merged, the cylinder 19 drives the filling device 20 to perform injection molding on the combined module 5.

[0045] Embodiment 3: Based on the above embodiment 2, the demoulding method is further described in detail, and reference can be made to 3 to 9. The specific method is as follows:

[0046] Furthermore, the support assembly 8 includes a mounting block 21 fixedly mounted on a middle group of the three groups of baffles 12, and a mounting shell 22 fixedly mounted on one side of the mounting block 21, and the mounting shell 22 is used for limiting.

[0047] Furthermore, the extrusion assembly 9 includes a housing 23 slidably connected in the mounting shell 22 , a guide block 24 is fixedly mounted on one side of the housing 23 , and a limit block 25 is also fixedly mounted in the housing 23 .

[0048] Furthermore, the pushing assembly 10 includes a spring 26 fixedly installed inside the housing 23, a push rod 27 is fixedly installed at one end of the spring 26, an inclined groove 28 is opened on the push rod 27, a limiting rod 29 is slidably connected in the inclined groove 28, and both ends of the limiting rod 29 are in contact with the side walls of the limiting block 25.

[0049] Among them, when the cylinder 17 pulls the baffle 12 to separate the two combined modules, the baffle 12 moves toward the demolding part 7 until it moves to the push rod 27, driving the push rod 27 to press against the spring 26 inside the shell 23. Due to the cooperation of the inclined groove 28 and the limit rod 29, the transmission of the inclined surface drives the guide block 24 to move in the opposite direction, thereby causing the guide block 24 to move toward the direction of the mold assembly 5.

[0050] The limiting rod 29 is divided into an inclined rod and blocks at both ends of the inclined rod. In the initial state, the inclined groove 28 on the top rod 27 is located at a lower position of the inclined rod. When the top rod 27 moves, and under the action of the limiting block 25, the inclined groove 28 moves toward the higher position of the inclined rod, thereby driving the housing 23 and the top rod 27 to move in the opposite direction.

[0051] Furthermore, the linkage assembly 11 includes a groove 30 provided on the mold clamping part 5, the guide block 24 is slidably connected in the groove 30, and a push block 31 is fixedly installed at the end of the guide block 24, and the shape of the push block 31 is the same as that of the model. When the housing 23 and the ejector 27 move in the opposite direction, the push block 31 on the guide block 24 is driven to push the manufactured mold, and when the push block 31 pushes the mold to be demoulded at the upper edge of the mold, the mold after injection molding is slightly tilted, which is convenient for the operator to remove it better, and a gap is generated between the side of the mold and the mold clamping part 5.

[0052] Furthermore, the linkage assembly 11 also includes a cooling pipe 32 movably installed inside the guide block 24, the cooling pipe 32 is installed on the baffle 12, a cavity 33 is opened in the cooling pipe 32, and a spring 2 34 is fixedly installed in the cavity 33, a piston is also fixedly installed at one end of the spring 2 34, and the piston is fixedly installed on the push plate, wherein when the push plate pushes the mold, the spring 2 34 is driven to stretch the piston and separate from the cavity 33, and at the same time of separation, cold air enters into the clamping part 5 from the cavity 33.

[0053] Furthermore, the push block 31 is in contact with the edge of the mold clamping member 5 , and the push block 31 is disposed at the upper half of the mold clamping member.

[0054] Among them, when cold air enters, cold air entering from the top can reduce the temperature of the mold and the product more quickly, because the density of cold air is greater than that of hot air, and it will sink naturally. This can accelerate the cooling speed of the product, shorten the molding cycle, and improve production efficiency. At the same time, due to the friction between the surface of the product and the surface of the mold, white or bright spots appear on the surface of the product. Cold air entering from the top helps to reduce the temperature difference between the product and the mold, thereby reducing the occurrence of the white top phenomenon. By optimizing the cooling process, the device can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0055] In summary, when injection molding is required, the operator controls the driving shaft on the cylinder 17 to descend, driving the two ends of the articulated rod 15 and the articulated rod 2 16 that are in contact with each other to descend into a "V" shape, thereby driving a group of baffles 12 to be slidably connected to the frame 13. Since the side of the baffle 12 opposite to the control console 6 is fixedly installed with a closing mold 5, the two combined modules 5 can be merged under the drive of the cylinder 17.

[0056] When the two combined molds 5 are combined, the oil cylinder 19 drives the filling device 20 to perform injection molding on the combined mold 5.

[0057] After the injection molding is completed, the cylinder 17 is used to pull the baffle 12 to separate the two combined modules, and the baffle 12 moves toward the demolding part 7 until it moves to the push rod 27, driving the push rod 27 to press against the spring 26 inside the shell 23. Due to the cooperation of the inclined groove 28 and the limit rod 29, the transmission of the inclined surface drives the guide block 24 to move in the opposite direction, thereby causing the guide block 24 to move toward the direction of the mold assembly 5.

[0058] The limiting rod 29 is divided into an oblique rod and blocks at both ends of the oblique rod. In the initial state, the oblique groove 28 on the push rod 27 is located at a lower position of the oblique rod. When the push rod 27 moves, and under the action of the limiting block 25, the oblique groove 28 moves toward the higher position of the oblique rod, thereby driving the shell 23 and the push rod 27 to move in the opposite direction. When the shell 23 and the push rod 27 move in the opposite direction, they drive the push block 31 on the guide block 24 to push the manufactured mold. When the push block 31 pushes the mold to be demoulded at the upper edge of the mold, the mold will be slightly tilted, which is convenient for the operator to remove it better. At the same time, a gap is generated between the side of the mold and the clamping part 5. The cold air entering from the upper end can reduce the temperature of the mold and the product more quickly. Because the density of cold air is greater than that of hot air, it will sink naturally. This can speed up the cooling of the product, shorten the molding cycle, and improve production efficiency. At the same time, due to the friction between the surface of the product and the surface of the mold, white or bright spots will appear on the surface of the product. The cold air entering from the top helps to reduce the temperature difference between the product and the mold, thereby reducing the occurrence of white top phenomenon. By optimizing the cooling process, this device can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
