Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold temperature controller technology, and in particular to a novel mold temperature controller that can quickly remove residual liquid from the mold cooling circuit. Background Technology
[0002] A mold temperature controller is a device used to control the temperature of a mold, primarily for injection molding, extrusion molding, and die casting of materials such as metals or plastics. The working principle of a mold temperature controller is to control the mold temperature by heating or cooling the mold, thus maintaining a stable mold temperature and improving product quality and production efficiency.
[0003] Molds that have been used for a long time by a water temperature mold temperature controller may experience blockages or narrowing of the water channels due to corrosion. This reduces the cross-section of the cooling water channels in the mold and narrows the cooling passages, greatly reducing the heat exchange between the coolant and the mold. This seriously affects the cooling effect of the mold, leading to unstable product quality, reduced production efficiency, and increased costs.
[0004] Furthermore, if the mold is disassembled and moved without cleaning the residual water in the pipes, the residual liquid will flow around the molding machine, drip onto the workshop floor and the storage area, and the water remaining in the mold will corrode the cooling pipes over time.
[0005] Currently, some people are using compressed air to directly introduce into the pipes inside the mold to remove residual moisture. However, when the compressed air enters the pipes, the compression force is too strong, and the residual liquid will spray out directly from the pipe inlet or outlet, splashing everywhere into the surrounding environment, such as on people, the outer surface of the mold, and the ground. This poses problems such as accidental inhalation, mold corrosion, and ground pollution. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a new type of mold temperature controller that can quickly remove residual liquid in the mold cooling circuit. It has a simple structure and layout and can quickly remove residual liquid in the pipeline.
[0007] To achieve the above objectives, the present invention employs the following:
[0008] This utility model provides a novel mold temperature controller for quickly removing residual liquid from the mold cooling circuit. It includes a chassis with an electrical control box at the front. Inside the chassis are a water pump, a heating cylinder, and a float cylinder. Outside the chassis are exposed cooling inlet and cooling outlet pipes. The inlet of the water pump is connected to the outlet of the heating cylinder, and the outlet of the water pump is connected to the cooling outlet pipe. The inlet of the heating cylinder is connected to the cooling inlet pipe, and the float cylinder is connected to the heating cylinder by a pipe.
[0009] Wherein: the ends of the cooling inlet pipe and the cooling outlet pipe are respectively connected to a first main valve and a second main valve. The first main valve and the second main valve are respectively connected to a No. 1 one-to-four connector and a No. 2 one-to-four connector. The No. 1 one-to-four connector has four first branch pipes, and the No. 2 one-to-four connector has four second branch pipes. Each of the four first branch pipes and the four second branch pipes is equipped with an independent valve switch. Both the first branch pipes and the second branch pipes can be connected to external hoses.
[0010] Furthermore, the No. 1 one-to-four connector includes a first docking head and four first branch pipes. The first docking head is connected to the first main valve, and the four first branch pipes are symmetrically arranged at the four corners on one side of the first docking head and are all connected to the first docking head.
[0011] Furthermore, the No. 2 one-to-four connector includes a second docking head and four second branch pipes. The second docking head is connected to the second main valve, and the four second branch pipes are symmetrically arranged at the four corners on one side of the second docking head and are all connected to the second docking head.
[0012] Furthermore, it also includes a filter, which is disposed inside the chassis and between the cooling inlet pipe and the inlet end of the heating cylinder.
[0013] Furthermore, it also includes a drain pipe, which is connected to the bottom of the heating cylinder and protrudes outward from the outside of the chassis.
[0014] Furthermore, the chassis is configured as a cuboid structure, and one side of its top is chamfered.
[0015] Compared with the prior art, the present invention has the following technical effects: The present invention has a simple structure and reasonable design; by installing a first main valve and a second main valve on the cooling inlet pipe and cooling outlet pipe of the mold temperature controller respectively, and by connecting the first main valve and the second main valve to the outside of the mold with a No. 1 1-to-4 connector and a No. 2 1-to-4 connector respectively, the first main valve and the second main valve can be closed at the end of production, and a hose can be connected to the No. 1 1-to-4 connector and the No. 2 1-to-4 connector to facilitate the introduction of compressed air. In this way, the residual liquid in the mold pipeline can be quickly drained without pollution, which is convenient to operate and has good flexibility. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components, and the connection between valve joints usually refers to a threaded connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] Example:
[0025] Please see Figures 1 to 3As shown. This utility model embodiment proposes a novel mold temperature controller for quickly removing residual liquid from the mold cooling circuit. It is mainly based on some improvements to the current mold temperature controllers. It includes a casing 1, with an electrical control box 110 set at the front of the casing 1. Inside the casing 1, there is a water pump 10, a heating cylinder 20, and a float cylinder 30. The water pump 10 is located at the bottom of the casing 1, the heating cylinder 20 is located on one side of the casing 1 and is arranged vertically, and the float cylinder 30 is located at the top of the casing 1. The casing 1 has an exposed cooling inlet pipe 40 and a cooling outlet pipe 50. The cooling inlet pipe 40 is located on the upper outer side of the casing 1, and the cooling outlet pipe 50 is located on the lower outer side of the casing 1. The inlet end of the water pump 10 is connected to the outlet end of the heating cylinder 20, and the outlet end of the water pump 10 is connected to the cooling outlet pipe 50. The inlet end of the heating cylinder 20 is connected to the cooling inlet pipe 40, and the float cylinder 30 is connected to the heating cylinder 20 by a pipeline.
[0026] The key improvement of this application lies in the following: The ends of the cooling inlet pipe 40 and the cooling outlet pipe 50 are respectively connected to a first main valve 60 and a second main valve 70, serving as a main opening and closing mechanism. The first main valve 60 and the second main valve 70 are respectively connected to a No. 1 one-to-four connector 80 and a No. 2 one-to-four connector 90. The No. 1 one-to-four connector 80 has four first branch pipes 820, and the No. 2 one-to-four connector 90 has four second branch pipes 920. Each of the four first branch pipes 820 and the four second branch pipes 920 is equipped with an independent valve switch a. Both the first branch pipes 820 and the second branch pipes 920 can be connected to external hoses. The four first branch pipes on the No. 1 one-to-four connector can work independently, forming multiple loops between each pair; similarly, the four second branch pipes on the No. 2 one-to-four connector can work independently, forming multiple loops between each pair. In other words, when removing residual liquid, it is not necessary to disconnect other inactive hoses; simply controlling the valve switches to block the loops is sufficient, thus saving efficiency.
[0027] See also Figure 4 The diagram shown illustrates the residual liquid removal process of the mold temperature controller.
[0028] After the mold production is completed, close the first main valve 60 and the second main valve 70.
[0029] Quickly connect a flexible hose to one of the first branches of the No. 1 one-to-four connector 80. This hose is connected to an external compressed gas supply source to allow compressed air to enter. Open the valve switch on this first branch to open the pipeline.
[0030] Next, quickly connect a flexible hose to the other first branch pipe of the No. 1 one-to-four connector 80. This flexible hose is connected to an interface of the pipeline inside the mold 2. Open the valve switch on the first branch pipe to open the pipeline. At the same time, ensure that the valve switches on the remaining two first branch pipes of the No. 1 one-to-four connector are in the closed state.
[0031] Quickly connect a flexible hose to one of the second branches of the No. 2 one-to-four connector 90. The flexible hose connects to another interface of the pipeline inside the mold, and open the valve switch on the second branch to open the pipeline.
[0032] Quickly connect another flexible hose to the other second branch pipe of the No. 2 1-to-4 connector 90 as a discharge hose. Connect this hose to the collection bucket 3 (or directly to the main drainage pipe of the workshop) and open the valve switch on this second branch pipe to open the pipeline. At the same time, ensure that the valve switches on the remaining two second branch pipes of the No. 2 1-to-4 connector are in the closed state.
[0033] At this point, turn on the compressed gas supply source and supply compressed gas from the No. 1 1-to-4 connector. The compressed gas will quickly push the liquid in the pipe inside mold 2 through the No. 2 1-to-4 connector to the workshop drainage main pipe or collection bucket, ensuring that the residual liquid will not spread into the environment. After the compressed air is introduced for 1-2 minutes, stop the operation. Finally, pull out all hoses, close the corresponding valve switches, and open the first main valve and the second main valve to start the next work of heating or cooling the mold with the mold temperature controller.
[0034] The No. 1 four-way connector 80 and the No. 2 four-way connector 90 are both highly symmetrically designed. The No. 1 four-way connector 80 includes a first mating head 810 and four first branch pipes 820. The first mating head 810 is connected to the first main valve 60. The four first branch pipes 820 can also communicate with each other when the valve is fully open. The four first branch pipes 820 are symmetrically arranged at the four corners on one side of the first mating head 810 and are all connected to the first mating head 810. The No. 2 four-way connector 90 includes a second mating head 910 and four second branch pipes 920. The second mating head 910 is connected to the second main valve 70. The four second branch pipes 920 can also communicate with each other when the valve is fully open. The four second branch pipes 920 are symmetrically arranged at the four corners on one side of the second mating head 910 and are all connected to the second mating head 910. The No. 1 and No. 2 four-way connectors can also directly use existing mold temperature controller flow divider valves.
[0035] It also includes a filter 210, which is installed inside the housing 1 and between the cooling inlet pipe 40 and the inlet end of the heating cylinder 20. The filter ensures the cleanliness of the refrigerant entering the heating cylinder, reducing the need for subsequent maintenance of the heating cylinder.
[0036] It also includes a drain pipe 220, which is connected to the bottom of the heating cylinder 20 and protrudes outward from the outside of the casing 1. The drain pipe is used to periodically discharge the sewage, impurities or gas accumulated in the heating cylinder to ensure the normal operation of the heating cylinder.
[0037] The chassis 1 has a rectangular structure and a chamfered top side, which enables the mold temperature controller to have a compact structure and strong stability.
[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
