Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold which is easy to disassemble. Background Art

[0002] Injection mold is a processing tool used for mass production of parts with complex shapes. It mainly consists of two parts: a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, while the fixed mold is installed on the fixed template of the injection molding machine. During the injection molding process, the movable mold and the fixed mold are closed to form a gating system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic product. Although the structure of the injection mold varies depending on factors such as the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, its basic structure is the same. The mold is mainly composed of a gating system, a temperature control system, molding parts, and structural parts. Among them, the gating system and molding parts are the parts that are in direct contact with the plastic and change with the changes of the plastic and the product. They are the most complex, most variable, and require the highest processing finish and precision in the mold. Among them, easy disassembly is an important function of the injection mold.

[0003] For example, the Chinese patent "A kind of injection mold easy to disassemble" with announcement number CN214926497U includes a base, the middle end of the upper surface of the base is fixedly connected to the base, the middle end of the lower surface of the base is provided with a motor slot, the middle end of the bottom of the motor slot is fixedly connected to a servo motor, the output end of the servo motor passes through the middle end of the top of the inner cavity of the base and is fixedly connected to a first gear, the middle end of the right side of the inner cavity of the base is movably connected to a screw, the right side of the front of the screw is fixedly connected to a second gear, the first gear is meshed with the second gear, the left and right sides of the outer surface of the screw are threadedly connected to a second slider, the middle end of the upper surface of the second slider is fixedly connected to a second support column, the upper and lower ends of the inner side of the second support column are fixedly connected to a spring, the inner side of the spring is fixedly connected to a lower mold, the lower surface of the lower mold is in contact with the upper surface of the base, the lower end of the outer side of the second support column is provided with a fixed slot, the inner side of the top of the fixed slot is fixedly connected to a fixed rod, and the bottom end of the fixed rod is movably connected to a pulley.

[0004] Although the above-mentioned prior art can realize the rapid disassembly and assembly of the mold, in actual use, on the one hand, the disassembly and assembly of the movable mold is not flexible enough. When the movable mold is disassembled and assembled, the entire part of the movable mold needs to be removed, which increases the workload of the operator and thus reduces the production efficiency of the product. On the other hand, it is difficult to remove the product directly from the fixed mold after it is manufactured. When the product is manufactured, it is necessary to wait for the product to cool naturally before removing it from the fixed mold, which causes the operator to wait for the product to cool naturally, thereby affecting the production of the next batch of products. Therefore, it does not meet the existing needs. In this regard, we propose an injection mold that is easy to disassemble. Utility Model Content

The water injection pipe and the water outlet pipe are connected by a flange, and the water injection pipe extends to the bottom of the operating table and is fixedly connected to the upper end of the water tank.

[0012] Preferably, a rubber pad is provided at the upper end of the fixing rod, the rubber pad is fixedly connected to the fixing rod, and the upper end of the rubber pad contacts the upper end surface of the slide groove.

[0013] Preferably, hydraulic telescopic devices are fixedly provided at the four corners of the lower end of the mounting plate, and the fixed ends of the hydraulic telescopic devices are fixedly connected to the operating table.

[0014] Preferably, a movable mold is provided at the lower end of the fixing rod below the fixing seat, and the movable mold is fixedly connected to the fixing rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can quickly disassemble and assemble the movable mold through the arc-shaped clamping plate and the clamping groove. When the movable mold needs to be disassembled and assembled, the rotating rod is first rotated to make the rotating rod move outward through the external thread. At this time, the moving rotating rod drives the arc-shaped clamping plate to move together, so that the arc-shaped clamping plate is disengaged from the clamping groove, and then the movable mold is taken out of the slide groove together with the fixed rod. When installing the movable mold, the fixed rod is aligned with the slide groove and pushed into the slide groove. At this time, the rotating rod is rotated again, so that the rotating rod drives the arc-shaped clamping plate to move inward together until the arc-shaped clamping plate re-enters the clamping groove, so that the arc-shaped clamping plate is clamped and fixed with the clamping groove, and the installation of the movable mold is completed, so that the disassembly and assembly steps of the movable mold are simplified and the workload of the operator is reduced.

[0017] 2. The utility model can quickly cool down the fixed mold through the water pump and the cooling chamber. When the injection molding operation is carried out, after the production of a product is completed, the water pump is turned on to draw the coolant in the water tank, and the coolant enters the cooling chamber through the water inlet pipe. At this time, the coolant with a lower temperature absorbs the temperature on the fixed mold and reduces the temperature of the product. When the temperature of the product drops, it can be removed from the fixed mold. At this time, the coolant that absorbs the temperature flows back to the water tank through the outlet pipe.

[0018] 3. The utility model is provided with a rubber pad, which can buffer and position the fixed rod in the slide groove. When injection molding is performed, the movable mold moves downward until the movable mold and the fixed mold contact and squeeze each other. When the movable mold squeezes the fixed mold, the rubber pad on the fixed rod is deformed, so that the rubber pad deforms and absorbs the squeezing force on the fixed rod. When the movable mold is installed, the fixed rod is aligned with the slide groove and pushed into the slide groove, and the fixed rod is continuously pushed upward until the rubber pad contacts the upper end surface of the slide groove. At this time, the positions of the clamping groove and the slide groove correspond to each other, so that the impact force prevents the fixed rod from directly contacting the upper end surface of the slide groove, and the clamping groove can be positioned at the same time.
