Description

Technical Field

[0001] The utility model relates to the technical field of mold temperature controllers, in particular to a cold and hot alternating device for an injection mold temperature controller. Background Art

[0002] A mold temperature controller, also known as a mold temperature control machine, was initially applied in the temperature control industry of injection molds. Later, with the development of the machinery industry, its application has become more and more extensive. Now, mold temperature controllers are generally divided into water temperature controllers and oil temperature controllers, and the temperature control accuracy can reach ±0.1°C. Mold temperature controllers are widely used in various industries such as plastic molding, die casting, rubber tires, rollers, chemical reaction kettles, bonding, and internal mixing. Generally speaking, it is called a temperature control device, including temperature control in both heating and cooling aspects; during the operation of the mold temperature controller, a cold and hot alternating device is required to achieve the heat preservation effect of the mold temperature controller.

[0003] The prior art such as the utility model with the publication number of CN116734481A discloses a cold and hot water exchange system for a mold temperature controller. This patent uses a box body, a heating device, and a driving device. The output end of the driving device is communicated with the heating device. The heating device and the driving device are respectively installed in the box body. An inlet water pipe group, an outlet water pipe group, a first branch pipe, and a second branch pipe are installed in the box body. The output end of the inlet water pipe group is communicated with the input end of the driving device. The input end of the outlet water pipe group is communicated with the output end of the heating device; a first pneumatic ball valve is installed on the first branch pipe; a second pneumatic ball valve is installed between the second branch pipe and the outlet water pipe group; spherical joints are respectively installed at the input end and the output end of the driving device; the structure of the present invention is simple. By increasing the water pipe ports, the one-to-one cold and hot water supply requirements are realized, which is convenient for wiring. The use of spherical joints reduces the phenomenon of frequently replacing the sealing rings in the prior art, can greatly reduce the possibility of shutdown caused by reasons such as equipment maintenance, and reduces the cost of after-sales and maintenance in the later stage, solving the problem that the existing joints of the mold temperature controller mainly adopt a flat joint plus sealing ring structure. In the high-temperature and high-pressure environment of the mold temperature controller, the sealing ring is easy to deform, resulting in poor sealing of the flat joint and water leakage.

[0004] The inventor found in daily work that during the use of the cold and hot alternating device of the mold temperature controller, the existing cold and hot alternating device of the mold temperature controller has a large volume, and due to the large number of internal components, the weight of the equipment is too heavy. When maintenance personnel install or maintain it, they need to use equipment such as forklifts to transfer it to the designated area. At the same time, because the equipment is in contact with the ground, during subsequent movement, the staff needs to use tools to lift it up before the transfer tool can be placed under the device, resulting in a complex transfer operation of the equipment and being unfavorable for the transfer operation. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the drawbacks existing in the prior art that during subsequent movement, workers need to use tools to lift it up before placing the transfer tool under the device, resulting in a relatively complex transfer operation of the equipment and being unfavorable for transfer operations. A hot and cold alternating device for an injection mold temperature controller is proposed.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions: A hot and cold alternating device for an injection mold temperature controller includes a fuselage, a pipeline interface, and an auxiliary component. The pipeline interface is installed on the side surface of the fuselage. A pipeline valve is installed on the surface of the fuselage. A pressure gauge is installed on the side surface of the fuselage. The auxiliary component is installed on the lower surface of the fuselage. The auxiliary component includes a positioning frame. The positioning frame is fixedly connected to the lower surface of the fuselage. A connecting frame is rotatably connected to the inner wall of the positioning frame. A U-shaped baffle is fixedly connected to the side surface of the connecting frame. A dial is installed on the side surface of the U-shaped baffle. A round hole is opened on the surface of the dial. A threaded column is fixedly connected to the inner wall of the dial at the round hole. A guiding hole is opened on the side surface of the U-shaped baffle. A positioning pin is slidably connected to the inner wall of the U-shaped baffle at the guiding hole. An engagement ring is installed on the surface of the positioning pin. A slot is opened on the inner wall of the engagement ring. The positioning pin is inserted into the inner wall of the slot. A roller is rotatably connected to the outer circumference of the engagement ring. By means of the dial fixed on the threaded column, workers can quickly rotate the threaded column with their own strength, so that the threaded column can engage with the positioning pin, thereby quickly moving the position of the positioning pin out of the slot, and the engagement ring loses its restraint and can be disassembled.

[0007] Preferably, the number of the U-shaped baffles is two. The two U-shaped baffles are symmetrically arranged left and right with respect to the connecting frame. The position of the dial can be clamped and restricted by the U-shaped baffles, thereby ensuring the stability of the dial in the installed state.

[0008] Preferably, the threaded column penetrates the side surface of the dial, and the threaded column is located inside the guiding hole. Through the cooperation of the threaded column and the dial, the adjustment operation of the position of the positioning pin can be realized.

[0009] Preferably, the number of the positioning pins is two. The two positioning pins are symmetrically arranged left and right with respect to the threaded column. The positioning column is threadedly connected to the surface of the threaded column. The position of the engagement ring can be restricted by the positioning pin under the restriction of the threaded column.

[0010] Preferably, a restraining assembly is provided on the lower surface of the fuselage, and the restraining assembly includes a T-shaped frame, which is fixedly connected to the lower surface of the fuselage, and the side surface of the T-shaped frame is fixedly connected to a guide rod, and a limiting hole is provided on the surface of the T-shaped frame, and the T-shaped frame is rotatably connected to the inner wall of the limiting hole with a positive and negative threaded rod, and the surface of the guide rod is slidably connected to the limiting stop frame, and the side surface of the limiting stop frame is fixedly connected with a connecting nut, and the side surface of the positive and negative threaded rod is fixedly connected with a knob, and the position of the limiting stop frame can be restrained by the guide rod, and its moving direction can be guided at the same time, and the knob installed at the end of the positive and negative threaded rod can be operated by the operator, so that the operator can quickly rotate the positive and negative threaded rod under his own strength.

[0011] Preferably, there are two limit stops, which are symmetrically arranged about the forward and reverse threaded rods, are socketed with the surfaces of the forward and reverse threaded rods, and are in contact with the surface of the roller. A groove is provided on the surface of the limit stop, which is matched with the positioning frame. By adjusting the position of the limit stop to the roller, the roller can be clamped with the cooperation of the connecting nut and the forward and reverse threaded rods.

[0012] Preferably, there are two connecting nuts, which are symmetrically arranged with respect to the positive and negative threaded rods. The connecting nuts are threadedly connected to the surfaces of the positive and negative threaded rods. The cooperation between the positive and negative threaded rods and the connecting nuts can push the limit stop frame to move during the rotation process.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, by providing auxiliary components and restraining components, when the device is used, the switch device of the device is turned on to power on, and the hot and cold water converted inside the device is delivered to the mold temperature controller; when the device needs to be moved, the knob is rotated clockwise, the knob drives the positive and negative threaded rods to rotate, the positive and negative threaded rods are meshed with the connecting nuts on both sides, and the connecting nuts on both sides, under the action of the positive and negative threaded rods, respectively pull the limit stop frames on both sides to disengage from the dial wheel, and when the dial wheel loses the restriction of the limit stop frame, the fuselage is pushed, and the fuselage is subjected to force to push the positioning frame, and the positioning frame is subjected to force. The connecting frame is pushed by force, and the connecting frame cooperates with the U-shaped baffle and the positioning pin to push the connecting ring. The connecting ring is pushed by force to push the roller, and the roller is rotated by force and guides the machine body to move; when the roller needs to be maintained or replaced, the dial is turned counterclockwise, and the dial drives the threaded column to rotate, and the threaded column engages with the positioning pins on both sides. The positioning pins on both sides slide into the guide hole under the action of the threaded column and disengage from the connecting ring. When the positioning pins are completely disengaged, the connecting ring loses its restriction, and then the staff can disassemble the connecting ring and the roller, so as to maintain or replace the roller;

[0015] When using the auxiliary component, it enables the staff to adjust the position of the equipment or transfer the equipment with their own strength. At the same time, by connecting the two positioning pins and a threaded column in a positive and negative thread manner, when the dial rotates, it can cooperate with the threaded column to adjust the positions of the two positioning pins, so that the two positioning pins can be disengaged from the connecting ring in a single operation without the aid of tools, making the disassembly operation of the roller more convenient than that of the existing roller. At the same time, the position of the dial can be restricted by the U-shaped baffle, increasing the stability of the dial while ensuring that the dial can be quickly rotated by the operator, thereby increasing the stability of the threaded column and ensuring that the position of the positioning pin can be restricted by the threaded column when the positioning pin meshes with the threaded column, thus guaranteeing the stability of the positioning pin in the restricted state. When the roller rotates, the movement mode of the universal wheel can be referred to, and the connecting ring is connected to the connecting frame through a structure, which can ensure that the staff can control the moving direction of the equipment when moving the equipment;

[0016] By setting the auxiliary component and the restraint component, it is convenient for the staff to transfer the equipment or adjust its position, thereby reducing the problem that it is difficult to transfer or adjust the equipment due to its heavy weight, further improving the convenience of equipment transfer, and at the same time raising the distance between the equipment and the ground, improving the efficiency of air circulation and increasing the heat dissipation effect of the equipment.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a hot and cold alternating device for an injection mold temperature controller, including a body 1, a pipeline interface 2 and an auxiliary component 5. The pipeline interface 2 is installed on the side surface of the body 1. A pipeline valve 3 is installed on the surface of the body 1. A pressure gauge 4 is installed on the side surface of the body 1. The auxiliary component 5 is installed on the lower surface of the body 1. A restraint component 6 is arranged on the lower surface of the body 1.

[0026] Next, specifically describe the specific settings and functions of its auxiliary component 5 and restraint component 6.

[0027] In this implementation: The auxiliary component 5 includes a positioning frame 51. The positioning frame 51 is fixedly connected to the lower surface of the body 1. A connecting frame 52 is rotatably connected to the inner wall of the positioning frame 51. A U-shaped baffle 53 is fixedly connected to the side surface of the connecting frame 52. A dial wheel 54 is installed on the side surface of the U-shaped baffle 53. A round hole is opened on the surface of the dial wheel 54. A threaded column 55 is fixedly connected to the inner wall of the dial wheel 54 at the round hole. A guide hole is opened on the side surface of the U-shaped baffle 53. A positioning pin 56 is slidably connected to the inner wall of the U-shaped baffle 53 at the guide hole. A connecting ring 57 is installed on the surface of the positioning pin 56. A slot is opened on the inner wall of the connecting ring 57. The positioning pin 56 is inserted into the inner wall of the slot. The outer circumference of the connecting ring 57 is rotatably connected to a roller 58. By the dial wheel 54 fixed on the threaded column, the staff can quickly rotate the threaded column 55 with the help of their own strength, so that the threaded column 55 can engage with the positioning pin 56, thereby quickly moving the position of the positioning pin 56 out of the slot, so that the connecting ring 57 loses restraint and can be disassembled.

[0028] Specifically, the number of the U-shaped baffles 53 is two. The two U-shaped baffles 53 are symmetrically arranged about the connecting frame 52. The position of the dial wheel 54 can be clamped and restricted by the U-shaped baffle 53, so as to ensure the stability of the dial wheel 54 in the installed state.

[0029] Specifically, the threaded column 55 penetrates through the side surface of the dial wheel 54, and the threaded column 55 is located inside the guide hole.

[0030] In this embodiment: Through the cooperation of the threaded column 55 and the dial wheel 54, the adjustment operation of the position of the positioning pin 56 can be realized.

[0031] Specifically, the number of the positioning pins 56 is two. The two positioning pins 56 are symmetrically arranged left and right with respect to the threaded post 55. The positioning post is threadedly connected to the surface of the threaded post 55. The position of the connecting ring 57 can be restricted by the positioning pins 56 under the restriction of the threaded post 55.

[0032] In this embodiment: The restraint assembly 6 includes a T-shaped frame 61. The T-shaped frame 61 is fixedly connected to the lower surface of the fuselage 1. A guide rod 62 is fixedly connected to the side surface of the T-shaped frame 61. A limiting hole is formed in the surface of the T-shaped frame 61. A left-right threaded rod 63 is rotatably connected to the inner wall of the limiting hole of the T-shaped frame 61. A limiting bracket 64 is slidably connected to the surface of the guide rod 62. A connecting nut 65 is fixedly connected to the side surface of the limiting bracket 64. A knob 66 is fixedly connected to the side surface of the left-right threaded rod 63.

[0033] In this embodiment: The position of the limiting bracket 64 can be restrained by the guide rod 62, and at the same time, its moving direction can be guided. At the same time, through the knob 66 installed at the end of the left-right threaded rod 63, it can be operated by the operator, so that the operator can quickly rotate the left-right threaded rod 63 with his own strength.

[0034] Specifically, the number of the limiting brackets 64 is two. The two limiting brackets 64 are symmetrically arranged left and right with respect to the left-right threaded rod 63. The limiting brackets 64 are sleeved on the surface of the left-right threaded rod 63. The limiting brackets 64 are abutted against the surface of the roller 58. A groove is formed in the surface of the limiting bracket 64. The groove is adapted to the positioning frame 51. By adjusting the position of the limiting bracket 64 to the roller 58, the roller 58 can be clamped under the cooperation of the connecting nut 65 and the left-right threaded rod 63.

[0035] Specifically, the number of the connecting nuts 65 is two. The two connecting nuts 65 are symmetrically arranged left and right with respect to the left-right threaded rod 63. The connecting nuts 65 are threadedly connected to the surface of the left-right threaded rod 63.

[0036] In this embodiment: By using the cooperation of the left-right threaded rod 63 and the connecting nut 65, the limiting bracket 64 can be pushed to move during rotation.

[0037] Working principle: When the device needs to be moved, rotate the knob 66 clockwise. The knob 66 drives the left - right threaded rod 63 to rotate. The left - right threaded rod 63 meshes with the connecting nuts 65 on both sides. Under the action of the left - right threaded rod 63, the two connecting nuts 65 respectively pull the two limit brackets 64 away from the dial 54. When the dial 54 loses the restriction of the limit brackets 64, the fuselage 1 is pushed. The fuselage 1 is pushed to act on the positioning frame 51. The positioning frame 51 is pushed to act on the connecting frame 52. The connecting frame 52 cooperates with the U - shaped baffle 53 and the positioning pin 56 to push the connecting ring 57. The connecting ring 57 is pushed to act on the roller 58. The roller 58 rotates under the force and guides the fuselage 1 to move. When the roller 58 needs to be maintained or replaced, turn the dial 54 counterclockwise. The dial 54 drives the threaded column 55 to rotate. The threaded column 55 meshes with the two positioning pins 56. Under the action of the threaded column 55, the two positioning pins 56 slide into the guide holes and disengage from the connecting ring 57. When the positioning pins 56 are completely disengaged, the connecting ring 57 loses its restriction. Then the staff can disassemble the connecting ring 57 and the roller 58, so as to maintain or replace the roller 58. By setting the auxiliary component 5 and the restraint component 6, it is convenient for the staff to transport the equipment or adjust its position, thus reducing the problem that the equipment is too heavy to be transported or adjusted, further improving the convenience of equipment transportation, at the same time raising the distance between the equipment and the ground, improving the efficiency of air circulation and increasing the heat dissipation effect of the equipment.
