Description

Technical Field

[0001] The present invention relates to the technical field of plastic injection molds, and particularly to a temperature control device for a plastic injection mold. Background Art

[0002] A plastic injection mold is a combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. Plastic molds are the mother of industry. The release of new products often involves plastics. Coordinated changes in the convex and concave molds and the auxiliary molding system of the mold can process a series of plastic parts with different shapes and sizes. During injection molding, the mold is clamped on an injection molding machine, molten plastic is injected into the molding cavity, and it cools and solidifies in the cavity. Then, the upper and lower molds are separated, and the product is ejected from the cavity by the ejection system and leaves the mold. Finally, the mold closes again for the next injection molding, and the entire injection molding process is carried out cyclically.

[0003] During the injection molding process, controlling the mold temperature is one of the key factors to ensure product quality and production efficiency. However, currently, when in use, the injection mold cannot control the temperature well, which easily leads to low-quality products. In severe cases, the products may be unusable. Therefore, a temperature control device for a plastic injection mold is needed. Summary of the Invention

By installing the control component, when using the injection mold, when it is necessary to reduce the temperature of the mold plate, the water in the water storage tank can be first pumped by the water pump through the water delivery pipe into the adjustment box, so that the mold plate can be cooled by the water. At the same time, before cooling, the water in the water storage tank can be cooled by the condensation pipe, and it can be adjusted at any time according to the temperature on the temperature display, avoiding the water temperature in the water storage tank being too high or too low, so that the temperature of the mold plate can be effectively adjusted, avoiding the situation of too high or too low temperature during mold production, and thus ensuring the quality of the produced products and improving the practicability of the device.

At the same time, before cooling, the water in the water storage tank can be cooled by the condenser pipe, and the adjustment can be made at any time according to the temperature on the temperature display, avoiding the water temperature in the water storage tank being too high or too low. Thus, the temperature of the mold plate can be effectively adjusted, avoiding the situation of too high or too low temperature during mold production, and further ensuring the quality of the produced products and improving the practicability of the device.

[0012] In the present invention, by installing a heating component, during the production of mold products, heating can be carried out using the heating plate at the bottom of the mold plate, thereby effectively improving the heating speed. At the same time, a temperature sensor can be used to monitor the temperature of the mold plate in real time. Thus, when it is necessary to reduce the temperature of the mold plate, first reduce the temperature of the heating plate, and then low-temperature water can be injected into the water storage tank.

A support plate 205 is provided at the bottom of the workbench body 1. A water pump 206 is fixedly connected to the top of the support plate 205. One end of the water pump 206 is fixedly communicated with a connecting pipe 207. The other end of the connecting pipe 207 is fixedly communicated with a water storage tank 208.

A drain pipe 212 is fixedly communicated with the other side of the adjustment box 201. The drain pipe 212 is fixedly communicated with the back of the water storage tank 208. By installing the control component 2, when using the injection mold, when it is necessary to reduce the temperature of the mold plate 202, the water in the water storage tank 208 can be first pumped by the water pump 206 and delivered to the adjustment box 201 through the water delivery pipe 211, so that the mold plate 202 can be cooled by the water. At the same time, before cooling, the water in the water storage tank 208 can be cooled by the condensing pipe 209, and it can be adjusted at any time according to the temperature on the temperature display 210 to avoid the water temperature in the water storage tank 208 being too high or too low.

[0021] In this embodiment, as Figure 2 shown, a water outlet pipe 213 is fixedly communicated with one side of the water storage tank 208. A control valve 214 is fixedly connected to the side surface of the water outlet pipe 213.

[0022] In this embodiment, as Figure 5As shown in the figure, a heating component 3 is provided inside the adjustment box 201. The heating component 3 includes a water storage bin 301, which is fixedly connected inside the adjustment box 201. A heat conduction plate 302 is fixedly connected to the top of the water storage bin 301, and the heat conduction plate 302 is fixedly connected inside the adjustment box 201.

At the same time, the temperature of the mold plate 202 can be monitored in real time by using the temperature sensor 304. When it is necessary to reduce the temperature of the mold plate 202, first reduce the temperature of the heating plate 303, and then low-temperature water can be injected into the water storage bin 301, so that the heat conduction plate 302 can be used to cool the heating plate 303 and the mold plate 202.

[0026] The usage method and advantages of the present invention: For this temperature control device for plastic injection molds, during use, the working process is as follows:

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when using an injection mold, when it is necessary to lower the temperature of the mold plate 202, the water in the water storage tank 208 can be first pumped by the water pump 206 through the water delivery pipe 211 into the adjustment box 201, so that the mold plate 202 can be cooled by the action of water. At the same time, before cooling, the water in the water storage tank 208 can be cooled by the condensing pipe 209, and it can be adjusted at any time according to the temperature on the temperature display 210 to avoid the water temperature in the water storage tank 208 being too high or too low. At the same time, when producing mold products, the heating plate 303 at the bottom of the mold plate 202 can be used for heating, so that the heating speed can be effectively increased. At the same time, the temperature sensor 304 can be used to monitor the temperature of the mold plate 202 in real time. Thus, when it is necessary to lower the temperature of the mold plate 202, the temperature of the heating plate 303 is first lowered, and then low-temperature water can be injected into the water storage chamber 301, so that the heating plate 303 and the mold plate 202 can be cooled by the heat conduction plate 302.
