DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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 of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0032] Embodiment one;

[0033] Please refer to Figures 1 to 9 The present application provides a technical solution: a plastic product injection molding equipment, comprising a drive assembly 3 slidably connected to the support 2 through the base 1, further comprising:

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

[0035] A mold closing assembly 5 is installed at the bottom of the injection molding assembly 4, one side of the mold closing assembly 5 is installed with a control console 6, and the control console 6 can control the operation of the injection molding assembly 4 and the drive assembly 3 when the control console 6 is triggered;

[0036] A demolding component 7, the demolding component 7 comprises a support assembly 8 fixedly installed on the support 2, an extrusion assembly 9 movably installed on the support assembly 8, a pushing assembly 10 for demolding installed at one end of the extrusion assembly 9, and a linkage assembly 11 for cooling installed on the pushing assembly 10.

[0037] When the device is in the injection mold, the operator drives the drive assembly 3 to tightly close the two mold closing assemblies 5 by using the control console 6, then performs injection molding above the mold closing assembly 5 by using the injection molding assembly 4, until the injection molding is completed, the mold closing assembly 5 is opened, and when the mold is opened, the extrusion assembly 9 and the pushing assembly 10 cooperate with each other to push the mold to demold at the upper edge of the mold, and cold air enters from the upper end of the mold closing assembly 5 to cool the mold.

[0038] When the pushing assembly 10 pushes the mold out of the mold at the upper edge of the mold, the injection mold is slightly inclined, which facilitates the operator to take it out better, and at the same time, a gap is formed between the side of the mold and the mold closing assembly 5, so that the cold air enters from the upper end to lower the temperature of the mold and the product faster, because the density of cold air is larger than that of hot air, it will sink naturally. In this way, the cooling speed of the product can be accelerated, the molding cycle can be shortened, and the production efficiency can be improved. 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 white spots. The device optimizes the cooling process, which can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0039] In example two, the specific process of injection molding is improved based on example one. For specific ways, please refer to Figures 1-2 ;

[0040] Further, the support 2 includes three sets of baffles 12 fixedly installed on the top of the base 1, and racks 13 are installed on the four corners of the three sets of baffles 12, and the three sets of baffles 12 are spaced apart and installed on the top of the base 1. The side surface of the baffle 12 is fixedly installed with a support rod 14, one side of the support rod 14 is hingedly connected with a hinge rod one 15, and the end of the hinge rod away from the support rod 14 is rotatably connected with a hinge rod two 16 through a shaft, and one end of the hinge rod two 16 is installed on the opposite side of the other set of baffles 12 through a connecting seat.

[0041] Further, the hinge of the hinge rod one 15 and the hinge rod two 16 is movably connected with a gas cylinder 17. When the gas cylinder 17 operates, the two ends of the hinge rod one 15 and the hinge rod two 16 that contact with each other are lowered into a "V" shape, and a set of baffles 12 is slidingly connected to the rack 13.

[0042] When the operator controls the drive shaft on the gas cylinder 17 to descend, the two ends of the hinge rod one 15 and the hinge rod two 16 that contact with each other are lowered into a "V" shape, thereby slidingly connecting a set of baffles 12 to the rack 13. Since the side of the baffle 12 opposite to the control console 6 is fixedly installed with a mold closing assembly 5, the two mold closing assemblies 5 can be combined or separated under the drive of the gas cylinder 17.

[0043] It should be noted that by means of the hinge rod one 15 and the hinge rod two 16, the length of the force arm can be increased, so that a larger torque can be obtained under the same pushing force of the gas cylinder 17, making it easier to move heavy objects. The connection of the hinge rod one 15 and the hinge rod two 16 can provide a certain elasticity and buffer, reduce the impact and vibration that may be generated when the gas cylinder 17 is directly pulled, and protect the moved baffle 12 and the gas cylinder 17 itself.

[0044] Further, the injection molding assembly 4 is fixedly installed on the injection molding rod 18 on the rack 13, the oil cylinder 19 for driving the injection molding rod 18 is installed at the top of the injection molding rod 18, and the filling device 20 for injection molding is installed on the oil cylinder 19. When the two combined mold modules 5 are combined, the oil cylinder 19 drives the filling device 20 to injection mold the combined mold module 5.

[0045] In the third embodiment, the demolding mode is further described in detail based on the second embodiment, and the specific mode can be referred to 3-9, and the specific mode is as follows.

[0046] Further, the support assembly 8 includes the mounting block 21 fixedly installed in the middle of the three baffles 12, and the mounting shell 22 fixedly installed on one side of the mounting block 21, and the mounting shell 22 is used for limiting.

[0047] Further, the extrusion assembly 9 includes the shell 23 slidingly connected in the mounting shell 22, the guide block 24 fixedly installed on one side of the shell 23, and the limiting block 25 fixedly installed in the shell 23.

[0048] Further, the pushing assembly 10 includes the spring one 26 fixedly installed in the shell 23, the top rod 27 fixedly installed at one end of the spring one 26, the inclined slot 28 formed in the top rod 27, and the limiting rod 29 slidingly connected in the inclined slot 28, and the two ends of the limiting rod 29 are in contact with the side wall of the limiting block 25.

[0049] When the cylinder 17 pulls the baffle 12 to separate the two combined mold modules, the baffle 12 moves towards the demolding component 7 until it moves to the top rod 27, and drives the top rod 27 to press the spring one 26 in the shell 23. Due to the cooperation of the inclined slot 28 and the limiting rod 29, the inclined surface drives the guide block 24 to move in the opposite direction, so that the guide block 24 moves towards the combined mold module 5.

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

[0051] Further, the linkage assembly 11 includes the groove 30 formed in the combined mold module 5, the guide block 24 slidingly connected in the groove 30, the push block 31 fixedly installed at the end of the guide block 24, and the push block 31 is set in the same shape as the mold. When the shell 23 and the top rod 27 move in the opposite direction, the push block 31 on the guide block 24 pushes the finished mold. When the push block 31 pushes the mold out of the mold, the injection molded mold will be in a slight inclined state, which is convenient for the operator to take down, and at the same time, a gap is generated between the side edge of the mold and the combined mold module 5.

[0052] Further, the linkage assembly 11 further comprises 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 formed in the cooling pipe 32, and a spring 34 is fixedly installed in the cavity 33, one end of the spring 34 is also fixedly installed with a piston, and the piston is fixedly installed on the push plate, wherein when the push plate pushes the grinding tool, the spring 34 is stretched to separate the piston from the cavity 33, and at the same time, cold air enters the mold closing module 5 from the cavity 33.

[0053] Further, the push block 31 is attached to the edge of the mold closing module 5, and the push block 31 is arranged at the upper half of the mold closing module.

[0054] Wherein, when the cold air enters, the cold air enters from the upper end, which can reduce the temperature of the mold and the product faster, because the density of cold air is larger than that of hot air, it will naturally sink. This can accelerate the cooling speed of the product, shorten the molding cycle, improve the production efficiency, and at the same time, due to the friction between the surface of the product and the surface of the mold, the phenomenon of white or bright spots appears 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 white phenomenon. The device can reduce the time and energy consumption required for cooling by optimizing the cooling process, thereby reducing the production cost.

[0055] In summary, when injection molding is needed, the operator controls the driving shaft on the air cylinder 17 to descend, which drives the two ends of the articulated rod one 15 and the articulated rod two 16 to contact each other to form a "V" shape, thereby driving a group of baffles 12 to slide on the rack 13. Because the side opposite to the control console 6 of the baffle 12 is fixedly installed with the mold closing module 5, the two mold closing modules 5 can be combined under the drive of the air cylinder 17.

[0056] When the two mold closing modules 5 are combined, the oil cylinder 19 drives the filling device 20 to injection mold the mold closing module 5.

[0057] After the injection molding is completed, the baffle 12 is pulled by the air cylinder 17 to separate the two mold closing modules, and then the baffle 12 moves towards the demolding component 7, until it moves to the ejector rod 27, drives the ejector rod 27 to press the spring one 26 inside the housing 23, and due to the cooperation of the inclined groove 28 and the limiting rod 29, the inclined surface drives the guide block 24 to move in the opposite direction, so that the guide block 24 moves towards the mold closing module 5.

[0058] The limiting rod 29 is divided into an inclined rod and a stopper at both ends of the inclined rod. In the initial state, the inclined groove 28 on the ejector rod 27 is located at the lower position of the inclined rod. When the ejector rod 27 moves, and under the action of the limiting block 25, the inclined groove 28 moves towards the higher position of the inclined rod, thereby driving the outer shell 23 and the ejector rod 27 to move in the opposite direction. When the outer shell 23 and the ejector rod 27 move in the opposite direction, the push block 31 on the guide block 24 pushes the finished mold. When the push block 31 pushes the mold out of the mold at the upper edge of the mold, the injection-molded mold will be in a slightly inclined state, which is convenient for the operator to take out. At the same time, a gap is generated between the side edge of the mold and the mold closing member 5. Cold air enters from the upper end, which can quickly reduce the temperature of the mold and the product. Because the density of cold air is greater than that of hot air, it will naturally sink. In this way, the cooling speed of the product can be accelerated, the molding cycle can be shortened, and the production efficiency can be improved. At the same time, due to the friction between the surface of the product and the surface of the mold, white spots or bright spots may appear on the surface of the product. The entry of cold air from the upper end helps to reduce the temperature difference between the product and the mold, thereby reducing the occurrence of whitening. The device optimizes the cooling process, which can reduce the time and energy consumption required for cooling, thereby reducing production costs.

[0059] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
