Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to an injection mold for an insulating sleeve for a parallel groove wire clamp. Background Art

[0002] The parallel groove clamp is used to connect aluminum stranded wires or steel core aluminum stranded wires with small and medium cross-sections and steel stranded wires of overhead lightning arresters at locations that do not bear tension, and is also used for jumper connections of non-linear pole towers. Power engineering materials (metal fittings) are used to connect conductors to each other and are mainly used in power line projects. Since the existing parallel groove clamps are made of metal, they are easily corroded by acid rain during actual use, the metal surface is easily oxidized, and if there is residual moisture in the parallel groove clamps, there is also a safety hazard of leakage. Therefore, an insulating sleeve for protecting the parallel groove clamps has now appeared.

[0003] The prior art discloses an insulating sleeve injection mold for a parallel groove wire clamp with a patent announcement number of CN215849271U. The above patent includes a first base and a second base. The upper surface of the second base is fixedly connected to a machine tool, the upper surface of the machine tool is fixedly connected to a main mounting plate, the upper surface of the first base is fixedly connected to a vertical plate, an injection molding cylinder is fixedly installed on one side of the main mounting plate, one end of the injection molding cylinder is connected to a telescopic column, one end of the telescopic column is fixedly connected to a second injection molding plate, a male mold is arranged on one surface of the second injection molding plate, a back plate is fixedly connected to the upper surface of the machine tool, a first injection molding plate is fixedly installed on one side of the back plate, and a female mold is arranged on one side of the first injection molding plate. The utility model sets a first injection molding plate and a second injection molding plate, and can start the injection molding cylinder to make the female mold on the first injection molding plate contact with the male mold on the second injection molding plate. At the same time, the injection molding insulating hot material is injected into the mold cavity through the discharge pipe and the connecting pipe. After waiting for molding, the extrusion cylinder is started to eject the molded insulating sleeve. However, there are still the following deficiencies in actual use: from a practical point of view, when the device demolds the molded insulating sleeve, it needs to cooperate with the extrusion cylinder to achieve the demolding effect. The mutual coordination between the device structures is required to be relatively precise, and coordination errors are prone to affect the demolding work efficiency, thereby reducing production efficiency.

[0004] Therefore, an insulating sleeve injection mold for a parallel groove wire clamp is needed to solve the problem that the structure requirements are high and it is not convenient to demould quickly and conveniently in the prior art. Utility Model Content

[0022] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the connecting pipe 4 is externally connected to the feed pipe, the connecting plate 5 and the limit block 703 are slidably arranged, and the mounting plate 1 opens a feed port below the mother mold 3 .

[0023] The cylinder 7 facilitates precise compression molding between the female mold 3 and the male mold 6 to improve molding quality. At the same time, the unloading mechanism 8 is used to facilitate rapid demoulding of the molded product to improve work efficiency.

[0024] Further as Figure 2 , Figure 3and Figure 4 As shown, it is worth specifically explaining that the unloading mechanism 8 includes an injection cavity 801, and the injection cavity 801 is matched with the male mold 6 and is opened on the left surface of the female mold 3. The front and rear sides of the injection cavity 801 are respectively provided with movable grooves 802 and are opened on the female mold 3. A push plate 803 is slidably arranged in the movable groove 802, and a sliding rod 804 is fixedly connected to one side of the push plate 803. The sliding rod 804 corresponds to a matching slide groove 805 opened in the female mold 3, and the push plate 803 is fixed in the slide groove 805. A spring 806 is fixedly installed, the injection cavity 801 is connected with the connecting pipe 4 through the first injection plate 2, the sliding rod 804 is protruded from the left surface of the female mold 3 through the slide groove 805, and the protruding part and the push plate 803 slide in the movable groove 802 The distance is consistent, which is convenient for saliva work. The movable groove 802 is set in a T shape. The movable groove 802 is set in the injection cavity 801 through the push plate 803, and is matched with the male mold 6 through the sliding rod 804 to improve the molding quality.

[0025] The male mold 6 squeezes the sliding rod 804, causing it to slide in the slide groove 805 and squeeze the spring 806. At the same time, the push plate 803 is squeezed and moves to slide in the movable groove 802. When the insulating sleeve in the injection cavity 801 is formed, the cylinder 7 is operated to separate the male mold 6 from the female mold 3. At this time, under the elastic force of the spring 806, the slide groove 805 pushes the sliding rod 804, and then the limit block 703 pushes the insulating sleeve formed in the injection cavity 801 to facilitate demolding.

At the same time, the male mold 6 squeezes the sliding rod 804, so that it slides in the slide groove 805 and squeezes the spring 806. At the same time, the pushing plate 803 is squeezed and moves to slide in the movable groove 802. After the insulating sleeve in the injection cavity 801 is formed, the male mold 6 is separated from the female mold 3 by the operation of the cylinder 7. At this time, under the elastic force of the spring 806, the slide groove 805 pushes the sliding rod 804, and then the limit block 703 pushes the insulating sleeve formed in the injection cavity 801, so that it is out of the injection cavity 801 for easy material discharge, realizing a reciprocating working process and improving production efficiency.

[0028] In summary: through the provision of the blanking mechanism 8, the molded insulating sleeve can be actively demolded quickly and conveniently, thereby improving the production efficiency of the insulating sleeve, and the coordination between the structures is simple and easy to implement; through the coordination of the cylinder 7 and the limiting slide bar 702, it is convenient to accurately extrude the male mold 6 and the female mold 3, thereby improving the molding quality, and at the same time, when the blanking mechanism 8 is extruded, while realizing the molding of the insulating sleeve, it is convenient to demold the molded insulating sleeve, thereby further improving work efficiency.
