DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

Embodiment 1:

In the production of plastic workpieces such as the housing of a fast charging charger, the female mold 1 and the male mold 2 are first molded together, and then the molten material is transported into the molding cavity formed by the female mold 1 and the male mold 2, and then the injection molding operation is performed. However, during the molten material transportation process, the flow of the molten material is prone to vibration, resulting in a high probability of a gap being generated between the molded female mold 1 and the male mold 2 under the influence of the vibration, resulting in a high probability of molten material leakage, which in turn affects the quality of the injection molded workpiece.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 10 and Fig. 13, a processing mold is provided, comprising a female mold 1 and a male mold 2 attached to the lower end of the female mold 1, four vertically arranged rectangular columns 21 are respectively installed at four corner positions between the male mold 2 and a bottom plate 3 located directly below the male mold 2, the four rectangular columns 21 are used in conjunction with each other to connect the male mold 2 with the bottom plate 3, a through groove 24 penetrating the male mold 2 is formed on the lower end surface of the male mold 2, an installation space is provided for a mold core 8 through the through groove 24, and a mold core 8 extending to the lower end of the through groove 24 and arranged vertically and with the upper end extending into the cavity of the female mold 1 is installed on the upper end of the through groove 24, and the mold core 8 is used for molding operation;

The handles of two vertically arranged card plates 11 whose lower ends extend into the U-shaped cover 22 are respectively arranged on the front and rear ends of the female mold 1, and the U-shaped covers 22 whose two lateral parts are inwardly fitted with the outer ends of the card plates 11 are respectively installed on the front and rear ends of the male mold 2. The card plates 11 are restricted by the U-shaped cover 22, and the front and rear end surfaces of the male mold 2 are both inwardly recessed to form a third groove 29. The third groove 29 provides installation space for components such as the card block 25, and then the card block 25 extending out of the third groove 29 and inwardly fitting with the handle of the card plate 11 and the card head at the lower end of the card block 25 is slidably connected in the third groove 29. The card block 25 is used in conjunction with the card plate 11 to achieve restricted installation between the female mold 1 and the male mold 2;

A first inclined surface 251 is provided at the upper corner of the inner end of the card block 25. The first inclined surface 251 facilitates the inward movement of the card block 25. The magnetic plate 26 is arranged on the middle of the inner end of the card block 25, and the electromagnet 28 located on the inner side of the magnetic plate 26 and arranged to be mutually attracted with the magnetic plate 26 is arranged on the inner wall of the third groove 29. The electromagnet 28 cooperates with the magnetic plate 26 to drive the card block 25 to move inward. Then, two first elastic members 27 are symmetrically arranged between the inner end of the card block 25 and the inner wall of the third groove 29. The two first elastic members 27 cooperate to make the card block 25 move outward. The first elastic member 27 can be a spring, and the electromagnet 28 and the magnetic plate 26 are arranged between the two first elastic members 27.

Two telescopic rods 252 located on the inner side of the first elastic member 27 are symmetrically installed between the inner end of the block 25 and the inner wall of the third groove 29. The two telescopic rods 252 are used together to guide the movement of the block 25. A cooling channel 81 with multiple bends is opened inside the mold core 8, which is located between the two fifth grooves 84 and both openings extend to the lower end of the mold core 8 and are located on the front and rear sides of the large trapezoidal block 45. The cooling channel 81 provides a flow channel for the coolant, thereby completing the cooling of the inside of the injection molded workpiece. The cooling channel 81 is manufactured by 3D printing so that the cooling channel 81 has multiple bends, thereby increasing the flow distance of the coolant and improving the cooling efficiency.

First, the two openings of the cooling channel 81 are connected to the cooling pipeline. When in use, the female mold 1 and the male mold 2 are closed, so that the card plate 11 moves toward the U-shaped cover 22, and the card plate 11 is inserted into the U-shaped cover 22, so that the card plate 11 is restricted by the U-shaped cover 22, effectively avoiding the probability of the card plate 11 being lifted up, and ensuring the subsequent locking effect, and the card head of the card plate 11 first contacts the first inclined surface 251, and the card plate 11 continues to move downward, and the first inclined surface 251 and the card plate 11 move relative to each other, so that the card block 25 moves inward along the third groove 29, thereby compressing the first elastic member 27, and the first elastic member 27 generates elastic force;

When the female mold 1 and the male mold 2 are molded together, the clamping head of the clamping plate 11 will move to the lower end of the clamping block 25, and under the elastic force of the first elastic member 27, the clamping block 25 will move outward and contact the handle of the clamping plate 11, thereby limiting the installation between the clamping block 25 and the clamping plate 11, realizing the limited installation of the female mold 1 and the male mold 2, effectively reducing the probability of a gap between the molded female mold 1 and the male mold 2 due to injection vibration, effectively reducing the probability of leakage, and effectively ensuring the quality of the injection molded workpiece;

After the female mold 1 and the male mold 2 are molded together, the upper part of the mold core 8 is located in the cavity of the female mold 1, thereby forming a molding cavity in the female mold 1, the male mold 2 and the mold core 8, and then the melt is transported into the molding cavity, and then the coolant is transported into the cooling channel 81 through the cooling pipeline, and the coolant flows in the cooling channel 81, thereby cooling the melt in the molding cavity, and then completing the molding operation in the molding cavity;

When the molding is completed, the electromagnet 28 is turned on first, so that an adsorption force is generated between the electromagnet 28 and the magnetic plate 26, and under the action of the adsorption force, the magnetic plate 26 and the clamping block 25 move inward, so that the clamping block 25 and the clamping head of the clamping plate 11 are misaligned, thereby releasing the restriction on the clamping plate 11, and then the mold opening operation is performed, and the draft angle of the traditional mother mold 1 is changed from 2.5° to 0.5°, which effectively avoids the probability of dragging on the appearance of the injection molded workpiece.

Embodiment 2:

As shown in Figures 1, 2, 3, 4, 5, 7, 9, 10, 11 and 12, both left and right end surfaces of the mold core 8 are recessed inward to form fifth grooves 84, the upper and lower ends of which extend to the upper and lower ends of the mold core 8 respectively. The fifth groove 84 provides installation space for the auxiliary block 47, and the auxiliary block 47 whose outer end surface coincides with the outer end surface of the mold core 8 and extends out of the lower side of the fifth groove 84 is arranged inside the fifth groove 84. The two auxiliary blocks 47 are used in combination to clamp the molded injection molded workpiece, and two guide rods 83 which are arranged horizontally and whose other ends are connected to the inner wall of the through groove 24 and penetrate the auxiliary block 47 and are slidably connected to the auxiliary block 47 are respectively installed on the inner walls of the two fifth grooves 84. The guide rods 83 are used to restrict the auxiliary block 47 on the one hand and guide the movement of the auxiliary block 47 on the other hand.

A small trapezoidal block 46 with a narrow inner and wide outer arrangement is arranged on the lower end of the auxiliary block 47, and a large trapezoidal block 45 located between the two auxiliary blocks 47 and arranged with a wide upper part and a narrow lower part, and the lower inclined surface of which is in contact with the upper inclined surface of the small trapezoidal block 46, is attached to the lower end of the mold core 8. The large trapezoidal block 45 and the small trapezoidal block 46 are used in conjunction with each other to make the two auxiliary blocks 47 move outward, and the upper end surface of the male mold 2 is recessed downward to form a second groove 23 connected with the through groove 24, and then the upper end surface is overlapped with the upper end surface of the male mold 2 and the frame-type push plate 48 slidably connected to the outer end of the mold core 8 is slidably connected in the second groove 23, and the injection molded workpiece is pushed by the frame-type push plate 48;

Four round rods 41 arranged vertically and located outside the through groove 24 and penetrating the male mold 2 and slidably connected to the male mold 2 are respectively installed at the four corner positions of the lower end of the frame push plate 48, and the movable plate 4 located inside the rectangular column 21 and below the small trapezoidal block 46 is connected to the upper end of the movable part of the lifting device whose fixed part is set at the upper end of the bottom plate 3. The movable plate 4 is driven to move up and down through the lifting device. The lifting device can use an electric push rod 44, and the upper end of the movable plate 4 is connected to the four round rods 41. The four round rods 41 are used in combination to connect the frame push plate 48 and the movable plate 4.

Two pull rods 42 which are arranged vertically and located on the inner side of the small trapezoidal block 46 and whose lower ends penetrate the movable plate 4 and are slidably connected to the movable plate 4 are symmetrically arranged on the lower end of the large trapezoidal block 45. The large trapezoidal block 45 is connected to the limit plate 43 through the pull rod 42, and two limit plates 43 located on the left and right sides of the lifting device and affixed to the lower end of the movable plate 4 are arranged on the lower end of the pull rod 42. The pull rod 42 is moved downward through the limit plate 43. A second inclined surface located in the through groove 24 and at the lower end of the frame push plate 48 is processed at the lower edge position of the outer end of the auxiliary block 47. The second inclined surface can provide an outward movement channel for the auxiliary block 47. Then, the second elastic member 82 located on the outer side of the guide rod 83 is installed between the outer end of the second inclined surface and the inner wall of the through groove 24. The auxiliary block 47 is returned to its original position through the second elastic member 82. The second elastic member 82 can be a spring.

After injection molding, the electric push rod 44 is first started to drive the movable plate 4 to move downward, and the limit plate 43, the pull rod 42 and the large trapezoidal block 45 are caused to move downward, so that the two small trapezoidal blocks 46 move outward, and then the two auxiliary blocks 47 move outward along the guide rod 83, on the one hand, the second elastic member 82 is compressed to generate elastic force, and on the other hand, the inner wall of the injection molded workpiece is clamped, which effectively prevents the injection molded workpiece from moving with the mother mold 1 when the mold is opened, effectively ensures the subsequent normal material removal operation, and effectively ensures the quality of the outer surface of the injection molded workpiece;

After the mold opening is completed, the electric push rod 44 is used to drive the movable plate 4 to move upward, thereby separating the movable plate 4 from the limit plate 43, and then releasing the downward movement of the limit plate 43, and under the elastic force of the second elastic member 82, the auxiliary block 47 returns to its original position inward, thereby releasing the clamping of the injection molded workpiece, and during the upward movement of the movable plate 4, the four round rods 41 will move upward, and then the frame push plate 48 will move upward along the mold core 8, and ensure that the upward movement distance of the frame push plate 48 is greater than 70mm, so that the injection molded workpiece moves upward along the mold core 8 to a predetermined distance, so that the mold core 8 and the injection molded workpiece are effectively separated, and then the injection molded workpiece is taken out, so as to realize convenient material removal operation for the injection molded workpiece, and effectively reduce the probability of material removal difficulty caused by adhesion between the injection molded workpiece and the mold core 8.

Embodiment three:

When a plastic workpiece is produced, the female mold 1 and the male mold 2 are first molded together, and then the molten material is transported into the molding cavity formed by the female mold 1 and the male mold 2, and then the injection molding operation is performed. After injection molding, heat is likely to remain on the surface of the molded workpiece, resulting in a certain softening property on the surface of the molded workpiece. During the mold opening and material taking process, the female mold 1 and the surface of the molded workpiece will move relative to each other. Due to the softening property, the surface of the molded workpiece is more likely to be damaged, which will affect the precision of the surface of the molded workpiece, and further affect the quality of the molded workpiece.

In order to solve the above problems, as shown in Figures 1, 2, 3, 4, 7 and 8, the left end surface of the mother mold 1 is recessed to the right to form a slide groove extending to the lower end of the mother mold 1 and located at the right end of the fixed part of the telescopic device. The slide groove provides an installation space for the slider 7, and the slider 7 is slidably connected in the slide groove. The slider 7 is used to provide an installation carrier for components such as the hollow column 74, and the movable part of the telescopic device whose fixed part is installed at the left end of the mother mold 1 is connected to the slider 7. The slider 7 is driven to move left and right through the telescopic device. The telescopic device can use a cylinder 6;

A hollow column 74 extending from the right end to the inner wall of the cavity of the female mold 1 and arranged vertically is installed on the upper side of the right end of the slider 7. Through the hollow column 74, a mounting carrier is provided for the hollow functional plate 75. The hollow functional plate 75 which is mutually fitted with the auxiliary block 47 located on the left is connected and arranged on the right end of the hollow column 74. The hollow functional plate 75 is used to assist the molding of the injection molded workpiece on the one hand, and to spray cold air outward on the other hand. A fourth groove 72 extending to the upper end of the male mold 2 and connected to the lower end of the slide groove is formed by being recessed to the right on the left end surface of the male mold 2. Through the fourth groove 72, a channel is provided for the movement of the rectangular block 71. Then, the rectangular block 71 installed at the lower end of the slider 7 is slidably connected in the fourth groove 72. The rectangular block 71 is used to provide a mounting carrier for the air pipe 5.

The right end surface of the slider 7 is recessed to the left to form an air channel 73, the other end of which extends into the rectangular block 71 and is connected to the hollow column 74. The air channel 73 is used to transport cold air. The air pipe 5 extending out of the left side of the fourth groove 72 and connected to the air channel 73 is installed on the left end of the rectangular block 71, and cold air is transported into the air channel 73 through the air pipe 5.

First, the air pipe 5 is connected and installed with the cold air pipeline. After the female mold 1 and the male mold 2 are molded, the cylinder 6 is started first, and then the slider 7 is driven to move rightward along the slide groove, and then the hollow column 74 is moved rightward, so that the hollow functional plate 75 moves rightward and fits with the auxiliary block 47 on the left side, and the hollow functional plate 75 is used to assist the injection molding operation;

After the injection molding is completed, the cylinder 6 is used to move the slider 7, the hollow column 74 and the hollow functional plate 75 to the left, and ensure that the slider 7, the hollow column 74 and the hollow functional plate 75 move to the left by more than 5 mm, thereby effectively separating the hollow functional plate 75 from the injection molded workpiece, effectively preventing the hollow functional plate 75 from affecting the subsequent mold opening and material taking operations, and then using the cold air pipeline to transport cold air into the air pipe 5, and then the cold air is sprayed into the cavity of the mother mold 1 along the air pipe 5, the air channel 73, the hollow column 74 and the hollow functional plate 75, to achieve effective cooling treatment of the outer surface of the injection molded workpiece, effectively reducing the probability of damage to the surface of the injection molded workpiece during the mold opening and material taking operations, effectively ensuring the accuracy of the surface of the injection molded workpiece, and improving the quality of the injection molded workpiece.

Embodiment 4:

The air pipe 5, air channel 73, hollow column 74 and hollow functional plate 75 are used to transport cold air to cool the surface of the injection molded workpiece. However, during the spraying of cold air, the surface of the injection molded workpiece is tightly fitted with the inner wall of the molding cavity of the mother mold 1, which can easily hinder the flow of cold air on the surface of the injection molded workpiece, resulting in the inability of the cold air to effectively cool other surfaces of the injection molded workpiece, which will affect the cooling effect.

In order to solve the above problems, as shown in Figures 4 and 5, a mold shell 12 whose lower end face overlaps with the lower end face of the mother mold 1 is installed in the cavity of the mother mold 1, and the upper end of the mold core 8 extends into the mold shell 12, so that a molding cavity is formed between the mold shell 12 and the mold core 8, and a first groove 14 is formed between the mold shell 12 and the cavity of the mother mold 1, and a plurality of connecting columns 13 located in the first groove 14 are evenly arranged between the outer end of the mold shell 12 and the inner wall of the cavity of the mother mold 1, and a plurality of connecting columns 13 are used in combination to connect the mold shell 12 and the mother mold 1, and the hollow column 74 passes through the mold shell 12, and the right end face of the hollow column 74 overlaps with the left wall surface inside the mold shell 12.

When in use, the cylinder 6 is used to move the hollow column 74 and the hollow functional plate 75 to the left, so that the right end of the hollow functional plate 75 enters the first groove 14, and then the cold air pipeline is used to transport cold air into the air pipe 5.
