Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold with adjustable injection space. Background Technology
[0002] Injection molds are specialized tools used in plastic injection molding processes. Their main function is to manufacture plastic products with complex shapes and high precision requirements. Molten plastic is injected into the mold cavity, and after cooling and solidification, the finished product is obtained. They are widely used in the production of various plastic parts and products, and are particularly suitable for mass production of products with complex geometries and high precision requirements, such as automotive parts, electronic casings, home appliances, and toys.
[0003] However, the injection space inside existing injection molds is difficult to adjust, especially when the products produced are of different sizes. The injection mold needs to be disassembled and adjusted, which is quite troublesome and inconvenient. In addition, after injection, the molded product inside the cavity does not cool down quickly, which affects the production efficiency of the product. Utility Model Content
[0004] The main purpose of this utility model is to provide an injection mold with adjustable injection space, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An injection mold with adjustable injection space includes a base, a lower mold fixedly mounted on the upper left side of the base, an adjustment device inserted through the lower end of the lower mold, a water tank fixedly mounted on the lower right side of the lower mold, a cooling device fixedly mounted on the upper rear side of the water tank, a support frame fixedly mounted on the upper rear side of the base, a hydraulic cylinder fixedly mounted on the upper front side of the support frame, and an upper mold fixedly mounted on the output end of the hydraulic cylinder.
[0007] Preferably, the cooling device includes a water pump, with a cooling pipe installed on the left end of the water pump and the upper left side of the water tank. An installation groove is formed inside the lower mold, and the cooling pipe is fixed within the installation groove. The water pump is fixedly installed at the upper rear of the water tank, and a controller is fixedly installed at the front left of the water tank. A cooling plate is fixedly installed on the lower inner wall of the water tank. The water pump draws coolant from the water tank and delivers it to the cooling pipe. When the coolant flows back into the water tank through the cooling pipe, it quickly removes heat from the lower mold, thereby accelerating product molding and improving the production efficiency of the device.
[0008] Preferably, the adjusting device includes an electric telescopic rod, the output end of which is fixedly mounted with a support base, and the upper end of the support base is fixedly mounted with a shaping plate, which is located inside the lower mold. The electric telescopic rod is controlled by a controller to extend and retract, thereby pushing the support base and the shaping plate thereon. This allows the shaping plate to adjust its height within the lower mold, thus adjusting the injection space within the injection mold.
[0009] Preferably, guide seats are fixedly installed at both the front and rear ends of the lower mold, and two guide pillars are fixedly installed at both the front and rear ends of the upper mold. The four guide pillars correspond vertically to the four guide seats. When the upper and lower molds are closed, the guide pillars on the upper mold can be inserted into the insertion holes on the guide seats, thereby improving the stability when the upper and lower molds are closed.
[0010] Preferably, the controller is electrically connected to the cooling plate, water pump, electric telescopic rod, and hydraulic cylinder.
[0011] Preferably, the mounting groove is U-shaped.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. When it is necessary to adjust the injection space of the injection mold, the electric telescopic rod is controlled by the controller at the upper end of the cooling device to extend and retract. The electric telescopic rod pushes the support seat and the sizing plate on it, and the sizing plate adjusts its height in the lower mold, thereby adjusting the injection space in the injection mold. In addition, when the upper mold and the lower mold are closed, the guide post on the upper mold can be inserted into the hole on the guide seat, thereby improving the stability when the upper mold and the lower mold are closed.
[0014] 2. After the injection molding process is completed, the coolant in the water tank is drawn out by the water pump on the cooling device and transported to the cooling pipe. When the coolant flows back to the water tank through the cooling pipe, it can quickly remove the heat from the lower mold, thereby accelerating product molding and improving the production efficiency of the device. In addition, the cooling plate is activated by the controller, which can cool the coolant in the water tank, further improving the heat dissipation effect of the device. Attached Figure Description

[0024] The cooling device 2 includes a water pump 20. A cooling pipe 21 is installed on the left end of the water pump 20 and the upper left side of the water tank 8. An installation groove 22 is opened in the lower mold 4, and the cooling pipe 21 is fixed in the installation groove 22. The water pump 20 is fixedly installed at the upper rear of the water tank 8. A controller 23 is fixedly installed at the front left side of the water tank 8. A cooling plate 24 is fixedly installed on the lower inner wall of the water tank 8. The installation groove 22 is U-shaped. The water pump 20 draws coolant from the water tank 8 and delivers it to the cooling pipe 21. When the coolant flows back to the water tank 8 through the cooling pipe 21, the heat in the lower mold 4 can be quickly removed, thereby accelerating product molding and improving the production efficiency of the device.
[0025] The adjustment device 3 includes an electric telescopic rod 30, with a support base 31 fixedly installed at the output end of the electric telescopic rod 30.

[0027] It should be noted that this utility model is an injection mold with an adjustable injection space function. First, the controller 23 is connected to an external power source. When it is necessary to adjust the injection space of the injection mold, the electric telescopic rod 30 is controlled to extend and retract by the controller 23 at the upper end of the cooling device 2. The electric telescopic rod 30 pushes the support base 31 and the shaping plate 32 on it. The shaping plate 32 is then height-adjusted within the lower mold 4, thereby adjusting the injection space within the injection mold. In addition, when the upper mold 7 and the lower mold 4 are closed, the guide post 41 on the upper mold 7 can be inserted precisely into the guide post 41. The coolant is pumped into the socket on the seat 40, thereby improving the stability when the upper mold 7 and the lower mold 4 are closed. After the injection molding is completed, the coolant in the water tank 8 is drawn out by the water pump 20 on the cooling device 2 and transported to the cooling pipe 21. When the coolant flows back to the water tank 8 through the cooling pipe 21, the heat in the lower mold 4 can be quickly removed, thereby accelerating the product molding and improving the production efficiency of the device. In addition, the cooling plate 24 is activated by the controller 23, which can cool the coolant in the water tank 8, further improving the heat dissipation effect of the device.
