Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold which is convenient for mold closing during plastic processing. Background Art

[0002] The development trend of injection molds is primarily toward high-precision, high-tech processes. The injection molding process can be broadly divided into several steps: mold closing, injection molding, pressure holding, cooling, mold opening, and product removal. Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped components. Specifically, it involves injecting heated, molten plastic into the mold cavity under high pressure using an injection molding machine. After cooling and solidification, the resulting molded product is obtained. Plastic molds are divided into two types based on their molding characteristics: thermosetting plastic molds and thermosetting plastic molds. With the continuous development of science and technology and the rapid progress of society, the application of plastic products is increasing, and with it, the use of injection molds.

[0003] At present, the existing injection molds are easily affected by the operation of the equipment and shake when opening and closing the mold, and then the mold opening and closing is not utilized, which makes the mold opening and closing inconvenient, affects the overall operation of the mechanism, and causes the mold clamping between the movable mold and the fixed mold to be unstable, resulting in flash on the plastic product. Summary of the Invention

[0005] A rack having a frame body for supporting the equipment structure;

[0006] A mold mechanism, which is used for molding plastic products, is mounted on the top of a frame, and a clamping assembly is mounted on the top of the mold mechanism;

[0007] The mold mechanism includes a base and a hydraulic cylinder. The bottom of the base is fixedly mounted on the middle of the top of the frame by screws. The hydraulic cylinder is fixedly mounted on the side of the outer side of the frame through a bracket. The top of the base is fixedly connected to the fixed mold. The output end of the hydraulic cylinder is fixedly mounted with a movable mold. The fixed mold and the movable mold are mounted at the same height to facilitate the movement of the movable mold so that the movable mold and the fixed mold can be closed. The clamping components are respectively mounted on the top of the fixed mold and the top of the movable mold. The clamping components are used to limit the fixed mold and the movable mold. A support guide column is fixedly mounted in the middle of the outer side of the base. The base, hydraulic cylinder and support guide pillars are all installed on the central axis of the frame. The bottom of the movable mold is slidably installed on the outer surface of the support guide pillar through a collar. The bottom of the movable mold and the bottom of the fixed mold are installed with a preheating assembly. The middle of the outer side of the fixed mold is installed with a gate assembly. By utilizing the extension and contraction of the output end of the hydraulic cylinder and the support of the support guide pillar, the movable mold can be linearly braked. Under the support and guiding action of the two symmetrical support guide pillars, the movable mold is not prone to shaking when moving, reducing the influence of external force and vibration, thereby facilitating the opening and closing of the movable mold and the fixed mold.

[0008] Among them, the preheating component is used to heat the movable mold and the fixed mold, and the preheating component includes an air duct, which is fixedly installed at the bottom of the fixed mold, and a fan and an air pipe are respectively installed at both ends of the air duct, and the air pipe and the air duct are slidably adapted. The outer side of the air pipe is coiled and installed at the side of the outer side of the movable mold. The air inlet end of the fan is connected with a connecting pipe, and the top of the connecting pipe is connected with a sleeve. The suction force of the fan is used to allow outside air to enter the sleeve, and the heat transfer principle is used to heat the gas to form a hot air flow, and the hot air flow is transported through the air duct to enter the air pipe, and is discharged from the air outlet end of the air pipe by using the air flow, so that the gas circulates smoothly. At this time, the movable mold will absorb the heat of the air pipe, so that the temperature of the movable mold itself increases, thereby achieving the preheating effect.

[0009] Preferably, the support guide pillars are installed directly below the movable mold, so that the movable mold can be supported and guided by the support guide pillars. The bases are evenly distributed at the bottom of the fixed mold, so that the fixed mold can be supported and made firm.

Under the support and heat conduction of the heat conducting plate, heat can be transferred to the gate sleeve through the conical guide hopper, thereby heating the gate sleeve and reducing the temperature difference between the gate sleeve and the discharge end of the injection molding machine.

[0013] Preferably, the position of the fan-shaped piece corresponds to the position of the fan-shaped slot, which facilitates the insertion of the fan-shaped piece into the fan-shaped slot. The conical guide hopper is installed in the middle of the gate sleeve, which facilitates the use of the conical guide hopper to evenly transfer heat to the gate sleeve.

[0014] At the same time, the fan-shaped piece is embedded in the fan-shaped groove, which not only makes the connection between the conical guide hopper and the gate sleeve firm, but also increases the contact area between the two, so that the gate sleeve is heated evenly.

[0015] Preferably, the clamping assembly includes a rectangular notch and a rectangular connecting block, the rectangular notch is opened at the top of the movable mold, the rectangular connecting block is fixedly installed at the side of the outer side of the fixed mold, the rectangular connecting block is installed at a position close to the top of the fixed mold, and circular clamping grooves are opened on both sides corresponding to the inner cavity of the rectangular notch, an elastic strip is fixedly installed at the side of the outer side of the rectangular connecting block, and a semicircular clamping block is fixedly installed in the middle of the outer side of the elastic strip, and a supporting module is installed inside the rectangular connecting block, and the positions of the rectangular notch and the rectangular connecting block correspond to each other. At this time, the left end of the rectangular connecting block is inserted into the rectangular notch, thereby limiting the movable mold, and as the movable mold continues to move to the right, the semicircular clamping block is embedded in it under the elastic force of the elastic strip, thereby completing self-locking, so that it is not easy for the movable mold and the fixed mold to offset, which is helpful for injection molding and makes it difficult for the injection molded product to have flash.

[0017] Preferably, the elastic strip is arc-shaped, and after being pressed, the elastic strip is easy to be elastically deformed. There are two elastic strips, and the two elastic strips are symmetrically arranged along the middle of the rectangular connecting block.

[0018] Preferably, the support module includes a circular through hole, which is opened in the middle of the rectangular connecting block. A spring is installed inside the circular through hole, and both ends of the spring are fixedly connected to cylindrical support members. The cylindrical support member is fixedly connected to the middle of the outer side of the elastic strip. The cylindrical support member is slidably adapted to the circular through hole. When the semicircular block is embedded in the circular slot, it can be moved by using the cylindrical support member, and under the elastic support of the spring, it is subjected to a top force, so that the semicircular block and the circular slot are firmly connected.

[0020] The present invention provides an injection mold that facilitates mold closing during plastic processing. It has the following beneficial effects:

[0021] 1. This plastic processing and injection mold is easy to close. It uses the extension and contraction of the output end of the hydraulic cylinder and is supported by the support guide pillar. In combination with the sliding adaptation of the bottom of the movable mold to the support guide pillar through the collar, the movable mold can be linearly braked. Under the support and guidance of the two symmetrical support guide pillars, the movable mold is not prone to shaking when moving, reducing the influence of external force and vibration, which helps to open and close the movable mold and the fixed mold.

[0022] Second, the plastic processing is convenient for the injection mold to close the mold. The suction force of the fan is used to allow the outside air to enter the sleeve, and the heat transfer principle is used to heat the gas to form a hot air flow. The hot air flow is transported through the air duct to enter the air pipe, and the air flow is discharged from the air outlet end of the air pipe, thereby making the gas flow smooth. At this time, the movable mold will absorb the heat of the air pipe, so that the temperature of the movable mold itself will increase, thereby achieving the preheating effect.

[0023] 3. The plastic processing is convenient for the injection mold to close the mold. The air pipe is curved, and the curved bend on the air pipe is in full contact with the movable mold, which increases the contact area and thus makes the heat transfer efficiency high.

[0024] Fourth, the plastic processing is convenient for the injection mold to close the mold. The air pipe and the air duct are adapted to each other by sliding. When the movable mold is moving, the right end of the air pipe can slide inside the air duct. The air pipe and the air duct can be used to cooperate and play a guiding role, making the overall movement of the movable mold more stable. The same structure is used to achieve multiple functions.

[0025] 5. The plastic processing is convenient for the injection mold to close the mold. The left end of the rectangular connecting block is inserted into the rectangular notch to limit the movable mold. As the movable mold continues to move to the right, the semicircular block is embedded in it under the elastic force of the elastic strip, thereby completing self-locking, making it less likely for the movable mold and the fixed mold to be offset, which is helpful for injection molding and makes it less likely for the injection molded product to have flash.

[0026] 6. The plastic processing is convenient for the injection mold to close the mold. When the semicircular block is embedded in the circular slot, it can be moved by the cylindrical support. Under the elastic support of the spring, it is subjected to a top force, so that the semicircular block and the circular slot are firmly connected.

[0027] 7. The plastic processing is convenient for the injection mold to close the mold. The clamping plate is clamped on the outside of the air channel. Under the support and heat conduction of the heat conductive sheet, the heat can be transferred to the sprue bushing through the conical guide hopper, thereby heating the sprue bushing and reducing the temperature difference between the sprue bushing and the discharge end of the injection molding machine. At the same time, the fan-shaped sheet is embedded in the fan-shaped slot, which not only makes the connection between the conical guide hopper and the sprue bushing firm, but also increases the contact area between the two, so that the sprue bushing is heated evenly.

The bottom of the movable mold 24 and the bottom of the fixed mold 23 are installed with a preheating assembly 26. The middle of the outer side of the fixed mold 23 is installed with a gate assembly 27. The staff starts the hydraulic cylinder 22 to work. By utilizing the extension and contraction of the output end of the hydraulic cylinder 22 and under the support of the support guide column 25, and in combination with the sliding adaptation of the bottom of the movable mold 24 and the support guide column 25 through the collar, the movable mold 24 can be linearly braked. Under the support and guiding action of the two symmetrical support guide columns 25, the movable mold 24 is not prone to shaking when moving, reducing the influence of external force and vibration, thereby facilitating the opening and closing of the movable mold 24 and the fixed mold 23.

[0044] The support guide pillars 25 are installed directly below the movable mold 24 to facilitate the use of the support guide pillars 25 to support and guide the movable mold 24.

The air inlet end of the fan 262 is connected with a connecting pipe 264, and the top of the connecting pipe 264 is connected with a sleeve 265. The sleeve 265 is installed on the injection molding machine on the top right of the frame 1. The injection molding machine generates its own heat, and the staff turns on the fan 262 to work. The suction force of the fan 262 is used to allow outside air to enter the sleeve 265, and the heat transfer principle is used to make The gas is heated to form a hot air flow, which is transported through the air channel 261, so that the hot air flow enters the air pipe 263 and is discharged from the air outlet end of the air pipe 263 by the air flow, thereby making the gas flow smooth. At this time, the movable mold 24 will absorb the heat of the air pipe 263, so that the temperature of the movable mold 24 itself increases, thereby achieving the preheating effect. The inner wall of the sleeve 265 is provided with an annular groove 266, and the inner wall of the sleeve 265 is provided with a linear groove 267. The linear groove 267 and the annular groove 266 are arranged crosswise to facilitate the outside air to enter the interior of the sleeve 265. A sealing sleeve 268 is fixedly installed at the end position of the outer side of the air pipe 263. The material of the sealing sleeve 268 is rubber, which has a sealing effect, thereby promoting the hot air in the air channel 261 to enter the air pipe 263.

[0046] By slidingly fitting between the air pipe 263 and the air channel 261, when the movable mold 24 is moving, the right end of the air pipe 263 can slide inside the air channel 261, and the air pipe 263 and the air channel 261 can be used to cooperate with each other to play a guiding role, so that the overall movement of the movable mold 24 is more stable.

[0047] The second embodiment, as Figures 1-8 As shown, based on the first embodiment:

[0048] The gate assembly 27 includes a gate sleeve 271 and a tapered guide hopper 273. The gate sleeve 271 is fixed to the middle of the outer side of the fixed mold 23 by screws. A fan-shaped groove 272 is provided on the tapered surface of the inner cavity of the gate sleeve 271. The tapered guide hopper 273 is embedded in the inner cavity of the gate sleeve 271. The tapered guide hopper 273 is fixedly connected to the gate sleeve 271 by screws. A heat conducting plate 274 is fixedly installed at the bottom of the tapered guide hopper 273, and a clamping plate 275 is fixedly installed at the bottom end of the heat conducting plate 274. The clamping plate 275 is clamped to the middle of the outer side of the air channel 261. A sector piece 276 is fixedly installed on the conical surface of the outer side of the conical guide hopper 273. The sector piece 276 is embedded in the inner part of the sector slot 272. With the clamping plate 275 clamped to the outer side of the air channel 261, and under the support and heat conduction effect of the heat conductive sheet 274, heat can be transferred to the sprue bushing 271 through the conical guide hopper 273, thereby heating the sprue bushing 271 and reducing the temperature difference between the sprue bushing 271 and the discharge end of the injection molding machine.

[0049] At the same time, the fan-shaped piece 276 is embedded in the fan-shaped groove 272, which not only ensures a firm connection between the conical guide hopper 273 and the gate sleeve 271, but also increases the contact area between the two, so that the gate sleeve 271 is heated evenly.

[0050] The position of the fan-shaped piece 276 corresponds to the position of the fan-shaped slot 272, which facilitates the insertion of the fan-shaped piece 276 into the fan-shaped slot 272. The conical guide hopper 273 is installed in the middle of the gate sleeve 271, which facilitates the use of the conical guide hopper 273 to evenly transfer heat to the gate sleeve 271.

[0051] The third embodiment, as Figures 1-6 and Figures 9-11 As shown, based on the first embodiment:

[0052] The clamping assembly 3 includes a rectangular notch 31 and a rectangular connecting block 32. The rectangular notch 31 is opened at the top of the movable mold 24. The rectangular connecting block 32 is fixedly installed at the side of the outer side of the fixed mold 23. The rectangular connecting block 32 is installed near the top of the fixed mold 23. Circular card grooves 33 are opened on both sides of the inner cavity of the rectangular notch 31. An elastic strip 34 is fixedly installed on the side of the outer side of the rectangular connecting block 32. A semicircular card block 35 is fixedly installed in the middle of the outer side of the elastic strip 34. The interior of the rectangular connecting block 32 is installed with The supporting module 36, when the movable mold 24 moves to the left, uses the corresponding positions of the rectangular notch 31 and the rectangular connecting block 32. At this time, the left end of the rectangular connecting block 32 is inserted into the rectangular notch 31, thereby limiting the movable mold 24. As the movable mold 24 continues to move to the right, the semicircular clamping block 35 is embedded inside under the elastic force of the elastic strip 34, thereby completing self-locking, making it less likely for the movable mold 24 and the fixed mold 23 to be offset, thereby facilitating injection molding and making it less likely for the injection molded product to have flash.

[0053] The position of the rectangular notch 31 corresponds to the position of the rectangular connecting block 32, which facilitates the insertion of the rectangular connecting block 32 into the interior of the rectangular notch 31, thereby promoting the adaptation between the rectangular connecting block 32 and the rectangular notch 31. The circular slot 33 and the semicircular block 35 are installed at the same height, which facilitates the semicircular block 35 to be clamped into the interior of the circular slot 33.

[0054] The elastic strip 34 is arc-shaped and can be elastically deformed when pressed. Two elastic strips 34 are provided, and the two elastic strips 34 are symmetrically arranged along the middle of the rectangular connecting block 32 .

[0055] The supporting module 36 includes a circular through hole 361, which is opened in the middle of the rectangular connecting block 32. A spring 363 is installed inside the circular through hole 361. Both ends of the spring 363 are fixedly connected to cylindrical support members 362. The cylindrical support member 362 is fixedly connected to the middle of the outer side of the elastic strip 34. The cylindrical support member 362 and the circular through hole 361 are slidably adapted. When the semicircular block 35 is embedded in the circular slot 33, it can be moved by using the cylindrical support member 362, and under the elastic support of the spring 363, it is subjected to a top force, so that the semicircular block 35 and the circular slot 33 are firmly connected.

[0056] The spring 363 is installed in the middle of the circular through hole 361 . The spring 363 and the cylindrical support member 362 are on the same straight line, so that the spring 363 can be used to apply elastic thrust to the cylindrical support member 362 .

[0057] When in use, first install the sleeve 265 on the injection molding machine on the right side of the top of the frame 1, and use the heat of the injection molding machine itself, and the staff will start the fan 262 to work, and use the suction force of the fan 262 to make the outside air enter the sleeve 265, and use the heat transfer principle to make the gas heated to form a hot air flow, and through the air channel 261, the hot air flow enters the air pipe 263, and uses the air flow to be discharged from the air outlet end of the air pipe 263, thereby making the gas flow smoothly. At this time, the movable mold 24 will absorb the heat of the air pipe 263, so that the movable mold 2 4, the temperature of the nozzle 271 is increased to achieve the preheating effect, and the clamping plate 275 is clamped on the outer side of the air channel 261. Under the support and heat conduction of the heat conductive sheet 274, the heat can be transferred to the sprue bushing 271 through the conical guide hopper 273, thereby heating the sprue bushing 271 and reducing the temperature difference between the sprue bushing 271 and the discharge end of the injection molding machine. At the same time, the fan-shaped sheet 276 is embedded in the fan-shaped clamping groove 272, which can make the conical guide hopper 273 and the sprue bushing 271 firmly connected and increase the contact area between the two, so that the sprue bushing 271 is heated evenly.

[0058] At this time, the staff starts the hydraulic cylinder 22 to work. By utilizing the extension of the output end of the hydraulic cylinder 22 and the support of the support guide pillar 25, and in combination with the sliding adaptation of the bottom of the movable mold 24 with the support guide pillar 25 through the collar, the movable mold 24 can be linearly braked. Under the support and guidance of the two symmetrical support guide pillars 25, the movable mold 24 is less likely to shake during movement, reducing the influence of external forces and vibrations.

[0059] Furthermore, the air pipe 263 and the air channel 261 are adapted to slide with each other. When the movable mold 24 moves, the right end of the air pipe 263 can slide inside the air channel 261. The air pipe 263 and the air channel 261 cooperate to guide the movable mold 24, thereby making the overall movement of the movable mold 24 more stable.

[0060] Moreover, when the movable mold 24 moves to the left, the rectangular notch 31 and the rectangular connecting block 32 correspond to each other, and the left end of the rectangular connecting block 32 is inserted into the rectangular notch 31, thereby limiting the movable mold 24. As the movable mold 24 continues to move to the right, the semicircular clamping block 35 is embedded therein under the elastic force of the elastic strip 34, thereby completing self-locking, so that the movable mold 24 and the fixed mold 23 are not easily offset.

[0061] When the semicircular block 35 is inserted into the circular slot 33, it can be moved by the cylindrical support 362, and under the elastic support of the spring 363, it is subjected to a pushing force, so that the semicircular block 35 and the circular slot 33 are firmly connected;

[0062] At this time, the injection molding machine installed on the top right side of the frame 1 can be used to inject the raw material into the gate sleeve 271, and then the injection molding process can be carried out under the cooperation between the movable mold 24 and the fixed mold 23. When the injection molding process is completed, the output end of the hydraulic cylinder 22 can be contracted again to make the movable mold 24 move to the left to open the mold, and the plastic product can be removed.

[0063] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
