Description

Technical Field

[0001] The invention belongs to the technical field of injection molding equipment, and in particular relates to an injection molding equipment with a self-cleaning structure. Background Art

[0002] Injection molding equipment, also known as injection molding machine or injection machine, is the main molding equipment used to make plastic products of various shapes from thermoplastics or thermosetting plastics using plastic molding molds. It is divided into vertical, horizontal, and all-electric types. Injection molding equipment can heat plastic and apply high pressure to the molten plastic, causing it to be ejected and fill the mold cavity. Its working principle is similar to that of a syringe used for injections. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (i.e., viscous flow state) plastic into the closed mold cavity. After solidification and shaping, the product is obtained. Each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part removal. After the plastic part is removed, the mold is closed again to start the next cycle.

[0003] With the continuous increase in production and living needs, the plastics industry has developed rapidly. Injection molding equipment occupies an important position in terms of both quantity and variety. Its total production accounts for 20%-30% of the entire plastic molding equipment, making it one of the fastest growing and most produced types of plastic machinery. Since injection molding equipment has the ability to form plastic products with complex shapes, precise dimensions or dense textures with metal inserts in one go, it is widely used in various fields such as national defense, electromechanics, automobiles, transportation, building materials, packaging, agriculture, culture, education, health and people's daily life. During the injection molding operation, the injection molding raw materials will be melted at high temperature and extruded, which will cause adhesion to the inner wall of the injection mold to a certain extent. In order to prevent the quality of subsequent injection molded parts from being affected, the injection mold needs to be cleaned.

[0004] The current method for cleaning injection mold grooves is usually to use dedicated equipment for cleaning after injection molding. However, this cleaning method requires repeatedly stopping the operation of the injection molding equipment and even repeatedly disassembling and assembling the equipment, which increases production costs and affects the injection molding production efficiency of the product.

[0005] To this end, we designed an injection molding equipment with a self-cleaning structure to solve the above problems. Summary of the Invention

A liquid storage tank 4063 is also provided on the inside of the injection molding tank 1 as a secondary storage structure for the cleaning liquid. A plurality of flushing nozzles 406 are connected to the inner surface of the liquid storage tank 4063 for performing self-cleaning operations in the injection molding tank 1, and the plurality of flushing nozzles 406 are respectively located at the positions of the through-holes 404. Adapt, and the flushing nozzle 406 passes through the through-hole 404, so that the flushing nozzle 406 is exposed in the injection molding tank 1, and the injection molding tank 1 is sprayed. The surface of the through-hole 404 is covered with a sealing ring 405, and the surface of the sealing ring 405 is provided with a cross-shaped notch, and the opening diameter of the cross-shaped notch is adapted to the flushing nozzle 406. When the flushing nozzle 406 is not in use, it is located in the cavity formed between the liquid storage tank 4063 and the inner movable plate 4. When in use, it passes through the sealing ring 405, and a cross seam is provided on the surface of the sealing ring 405. When the flushing nozzle 406 is extended, the sealing ring 405 is still closely attached to the outer edge of the pipe wall of the flushing nozzle 406, so that the flushing nozzle 406 can be extended without causing leakage of the cleaning liquid in the injection molding tank 1;

[0038] The inner surface of the liquid storage tank 4063 is also connected to the second horizontal push rod 403, and the output end of the second horizontal push rod 403 is connected to the inner movable plate 4, which moves the inner movable plate 4 horizontally to select whether to extend the flushing nozzle 406. The upper end of the flushing nozzle 406 is connected to the touch valve 4061, and the outer surface of the inner movable plate 4 is connected to the top block 4062. One end of the top block 4062 is adapted to the position of the touch valve 4061. When the inner movable plate 4 moves inward to prepare to extend the flushing nozzle 406 At the same time, the top block 4062 on one side of the inner movable plate 4 contacts the touch valve 4061 on the upper end of the flushing nozzle 406, thereby triggering the flushing nozzle 406. At this time, the flushing nozzle 406 is extended and the flushing nozzle 406 sprays cleaning liquid to flush the injection tank 1. After the flushing is completed, the top block 4062 is separated from the touch valve 4061, and the inner movable plate 4 moves outward to retract the flushing nozzle 406 into the cavity. The flushing nozzle 406 stops spraying and forms a protective layer in the cavity.

[0039] The two opposite side surfaces of the inner movable plate 4 are connected to the second sliders 401, and the second slide groove 402 is provided at the inner side of the injection molding groove 1 and the adaptation position of the inner movable plate 4. The second slider 401 slides with the second slide groove 402, and the stability of the inner movable plate 4 is enhanced when it moves laterally. The outer side of the injection molding groove 1 is connected to the longitudinal push rod 6, and a connecting plate 601 is installed above the injection molding groove 1.

The trigger switch 602 is electrically connected to the second transverse push rod 403. After the trigger switch 602 is sensed, it electrically drives the second transverse push rod 403, and the second transverse push rod 403 pushes the inner movable plate 4 laterally;

[0040] A bottom support plate 7 is installed at the bottom end of the injection molding tank 1, which serves as a supporting structure for the injection molding model and the cleaning liquid. The four top corners of the surface of the bottom support plate 7 are connected with pressure-sensing contact pieces 704 for gravity sensing the introduced mass of the cleaning liquid. The pressure-sensing contact pieces 704 are pre-set with trigger values. The sides of the bottom support plate 7 are connected with electric support rods 701. The electric support rods 701 serve as a movable connection structure of the bottom support plate 7 to maintain the longitudinal mobility of the bottom support plate 7. The pressure-sensing contact pieces 704 are electrically connected to the electric support rods 701. When the mass of the cleaning liquid in the injection molding tank 1 reaches the preset trigger value, the electric support rods 701 are electrically driven to move longitudinally, thereby opening the bottom surface of the injection molding tank 1 to discharge the cleaning liquid. The electric support rods 701 are electrically connected to the second transverse push rods 403. When the electric support rods 701 are stretched, they drive the bottom support plate 7 to move downward, and simultaneously trigger the second transverse push rods 403 to move in the opposite direction to close the flushing nozzles 406.

[0041] Example 2

[0042] like Figures 1-10As shown, the upper end of the injection molding tank 1 is connected to a telescopic bracket 3, and the top of the telescopic bracket 3 is connected to a top plate 301. The telescopic bracket 3 serves as a supporting structure of the top plate 301, and a mounting plate 203 is installed on the inner side of the top plate 301. The upper end of the mounting plate 203 is connected to the material tank 2, and the mounting plate 203 serves as a mounting support structure for the material tank 2. The input end of the injection molding gun head 201 is connected to the material tank 2, and the material tank 2 supplies the injection molding gun head 201 with injection molding raw materials. A contact block 3014 is connected to the upper surface of the top plate 301, and the upper part of the contact block 3014 is adapted to the position of the trigger switch 602. When the injection molding operation is performed, the telescopic bracket 3 drives the injection molding mechanism to perform longitudinal reciprocating movement The telescopic bracket 3 is an electric telescopic bracket 3. The injection molding frequency can be adjusted by presetting the control panel 5. When the injection molding operation is performed, the telescopic bracket 3 retracts, driving the injection molding mechanism to move downward to align the injection molding position and perform the injection molding operation. After completing a single injection molding operation, the electric telescopic bracket 3 is extended. At this time, the contact block 3014 connected to the surface of the top plate 301 moves up and contacts the trigger switch 602 to electrically start the second horizontal push rod 403. The cleaning mechanism starts to work and self-cleans the injection tank 1. The upper end of the material tank 2 is connected to the feeding pipe 202 to inject material into the material tank 2 to maintain the supply of injection molding raw materials.

[0043] Furthermore, the two opposite side surfaces of the mounting plate 203 are connected with a first slider 2031, and the inner surface of the top plate 301 is provided with a first slide groove 3011. The first slider 2031 is adapted to the position of the first slide groove 3011, and the first slider 2031 slides with the first slide groove 3011, so that the mounting plate 203 can be displaced laterally, thereby driving the injection molding mechanism to adjust its position to match the injection molding position of the mold and improve the accuracy of the injection molding operation. One end of the top plate 301 is connected to a fixed plate 3012, and a first horizontal push rod 3013 is threadedly connected to the inner side of the fixed plate 3012. The fixed plate 3012 serves as an installation support structure for the first horizontal push rod 3013.

[0044] A plurality of cleaning liquid tanks 407 are installed on the outer peripheral side of the injection tank 1. A connecting pipe 4072 is connected between the plurality of cleaning liquid tanks 407. The cleaning liquid tank 407 serves as a storage mechanism for the cleaning liquid, and the connecting pipe 4072 is used to maintain the liquid level balance between the cleaning liquid tanks 407. When the injection tank 1 is cleaned, the flushing pressure is consistent, thereby maintaining the flushing effect in the injection tank 1. A liquid guide tube 4071 is connected to the inside of the cleaning liquid tank 407. The output end of the liquid guide tube 4071 is connected to the liquid storage tank 4063. The liquid guide tube 4071 is used to The cleaning liquid in the cleaning liquid tank 407 is channeled to the liquid storage tank 4063 to supply the cleaning liquid to the flushing nozzle 406. The upper end of the cleaning liquid tank 407 is connected to a liquid filling port 408, and the liquid filling port 408 is used to continuously supply cleaning liquid to the cleaning liquid tank 407 to support the continuous processing of the injection molding equipment.

One end of the connector 4073 is connected to the injection molding tank 1, and the cleaning liquid tank 407 is installed and fixed using the connector 4073.

[0045] Furthermore, the two opposite outer surfaces of the bottom support plate 7 are connected with a third slider 702, and the two opposite inner surfaces of the injection molding groove 1 are provided with a third slide groove 703. The third slider 702 is adapted to the position of the third slide groove 703, and the third slider 702 and the third slide groove 703 are slidably matched. The third slider 702 is used to cooperate with the third slide groove 703 to maintain the structural stability of the bottom support plate 7 during the longitudinal movement of the bottom support plate 7, thereby avoiding leakage of cleaning liquid on the edge side of the bottom support plate 7 after long-term operation and extending the service life of the equipment. Several overflow grooves 705 are provided on the edge sides of the two opposite upper surfaces of the bottom support plate 7, and the output ends of the several overflow grooves 705 are kept flush with the side surface of the bottom support plate 7, which helps to drain the cleaning liquid and avoid splashing as much as possible during discharge, thereby reducing the pressure of later cleaning.

[0046] A control panel 5 is installed on the outer surface of the injection molding tank 1. The control panel 5 is electrically connected to the first transverse push rod 3013, the second transverse push rod 403, the touch valve 4061, the longitudinal push rod 6, the trigger switch 602 and the electric support rod 701 respectively. The control panel 5 serves as the master control component. In addition to automatic trigger control, each trigger mechanism can also use the control panel 5 to perform independent control of a single zone to enhance the controllability of the equipment operation.

[0047] A notch is provided on the inner surface of the side of the injection molding tank 1, and the inner movable plate 4 matches the specifications and dimensions of the notch. The notch serves as a accommodating space for the inner movable plate 4. The inner movable plate 4 is located in the notch when normally installed, and is only slightly protruding in the injection molding tank 1, which is convenient for injection molding operations. A base frame 8 is fixedly connected to the bottom end of the injection molding tank 1, and the base frame 8 is used to support and fix the injection molding equipment to enhance the stability of the equipment operation.

[0048] Working principle: During the use of the present invention, the material feeding tube 202 is first used to continuously feed the material trough 2, and the first horizontal push rod 3013 on one side of the fixed plate 3012 is started to push the supporting structure of the injection molding mechanism, that is, the mounting plate 203, horizontally to adjust the operating position of the injection molding mechanism according to the injection position of the injection mold groove to maintain the accuracy of the injection molding operation. After the injection molding position is determined, the telescopic bracket 3 is operated to move downward. At this time, the injection molding gun head 201 is used to perform the injection molding operation in the mold groove. After the injection molded part is cooled and formed, the injection molded part is taken out and the telescopic bracket 3 is synchronously lifted up. At this time, the contact block 3014 on the surface of the top plate 301 of the telescopic bracket 3 contacts the trigger switch 602 on the bottom surface of the connecting plate 601. The trigger switch 602 is electrically connected to the second horizontal push rod 403, that is, the second horizontal push rod 403 is triggered, and the second horizontal push rod 403 drives the inner movable plate 4 in the injection molding tank to bend and stretch outward, so that the flushing nozzle 406 connected to one side of the liquid storage tank 4063 passes through the sealing ring 405 and is exposed in the injection molding tank 1. During the process of the flushing nozzle 406 passing through, the top block 4062 on one side of the inner movable plate 4 comes into contact with the touch valve 4061 connected to the upper end of the flushing nozzle 406 and triggers the flushing nozzle 406, so that the flushing nozzle 406 quickly sprays out the flushing liquid. The flushing nozzles 406 evenly arranged on the four surfaces inside the injection molding tank 1 cooperate to perform full-range flushing in the injection molding tank 1, thereby maintaining the flushing efficiency and completion degree in the injection molding tank 1;

[0049] As the cleaning liquid is continuously injected into the injection tank 1, the cleaning liquid in the injection tank 1 forms a weight and presses the pressure-sensitive contact piece 704 provided on the surface of the bottom support plate 7. Since the trigger value of the pressure-sensitive contact piece 704 is pre-set, when the flushing purpose is achieved or the cleaning liquid in the injection tank 1 is full, the pressure-sensitive contact piece 704 immediately triggers the electric support rod 701, and the electric support rod 701 stretches, cooperating with the third sliding mechanism to drive the bottom support plate 7 downward, exposing the bottom surface of the injection tank 1, thereby quickly discharging the cleaning liquid that has completed the cleaning purpose;

[0050] When the bottom support plate 7 is pulled out, the movement of the electric support rod 701 synchronously triggers the second horizontal push rod 403, and the second horizontal push rod 403 pushes the inner movable plate 4 out. At this time, the top block 4062 on one side of the inner movable plate 4 is separated from the touch valve 4061 at the upper end of the flushing nozzle 406, and the flushing nozzle 406 stops spraying the flushing liquid. At the same time, the flushing nozzle 406 retracts from the sealing ring 405 into the cavity again as the inner movable plate 4 moves, hiding the flushing nozzle 406. After the cleaning liquid in the injection molding tank 1 is emptied, the electric support rod 701 contracts, driving the bottom support plate 7 to return to its normal position, and the injection molding operation can be carried out again.

[0051] The above-mentioned mechanism completes the self-cleaning operation of the injection molding equipment. Among them, the electric control mechanism adopted in the scheme, such as the first horizontal push rod 3013, the second horizontal push rod 403, the electric support rod 701, the touch valve 4061, the trigger switch 602 and the pressure sensing touch piece 704, are all existing technologies. This type of control mechanism directly adopts the existing mechanism.
