DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5The utility model provides a technical solution: an automobile wire tube injection molding device, comprising a first seat plate 1 and a second seat plate 2, a movable mold seat 3, a fixed mold seat 4 and a vertical plate 9 are arranged on the first seat plate 1, the movable mold seat 3 can move relative to the first seat plate 1, a cylinder 13 is arranged on the outer side surface of the second seat plate 2, one end of the cylinder 13 is connected to the core mold seat 5, the cylinder 13 includes a push rod, and the push rod is fixedly connected to the core mold seat 5, a plurality of groups of mold cores 6 are arranged on the core mold seat 5, a first inclined surface 7 is arranged on the movable mold seat 3, a second inclined surface 8 is arranged on the core mold seat 5, and a plurality of groups of mold cavities 12 are provided on the inner side surfaces of the movable mold seat 3 and the fixed mold seat 4.

[0024] The movable mold base 3 and the vertical plate 9 are connected via multiple groups of springs 10 .

[0025] The first seat plate 1 is provided with two sets of slide grooves 11 , and the movable mold seat 3 is slidably connected to the slide grooves 11 .

[0026] In the mold opening state, the movable mold base 3, the fixed mold base 4 and the core mold base 5 are in a separated state. When the mold is closed, the cylinder 13 works to drive the core mold base 5 to move, and the core mold base 5 drives multiple groups of mold cores 6 to move synchronously. The core mold base 5 is driven by the cylinder 13 to approach the movable mold base 3 and the fixed mold base 4. The second inclined surface 8 of the core mold base 5 contacts the first inclined surface 7 of the movable mold base 3 and applies an extrusion force to the first inclined surface 7, so that the movable mold base 3 slides along the slide groove 11, the spring 10 is stretched, and the movable mold base 3 approaches the fixed mold base 4. Figure 4 As shown, under the drive of the cylinder 13, the movable mold base 3, the fixed mold base 4 and the core mold base 5 are closed, and multiple groups of cores 6 of the core mold base 5 are embedded in the cavity 12 to form an injection molding chamber.

[0027] When the mold is opened after the injection molding is completed, the cylinder 13 drives the core mold base 5 and the multiple sets of mold cores 6 to reset, the external force applied to the first inclined surface 7 disappears, and the movable mold base 3 slides and resets along the slide groove 11 under the action of the rebound force of the multiple sets of springs 10. Figure 3 As shown, the injection molding chamber is automatically separated, and the wire tube molded part is automatically demoulded and falls by its own gravity.

[0028] Among them, two groups of guide rods 14 are arranged between the first seat plate 1 and the second seat plate 2, and the guide rods 14 penetrate the core mold base 5. The core mold base 5 and the guide rods 14 are slidably connected by guide sleeves 15. The two groups of guide rods 14 play a guiding role. When the core mold base 5 moves, it slides along the axial direction of the guide rods 14 to limit the movement direction of the core mold base 5, that is, to limit the movement direction of multiple groups of core molds 6, so as to avoid the core mold 6 from being offset when the mold is closed, thereby improving the injection molding quality of the automotive wire tube.

[0029] When the mold is closed, the second inclined surface 8 cooperates with the first inclined surface 7 to further play a guiding role, so that the movable mold base 3, the fixed mold base 4 and the core mold base 5 can achieve precise positioning and mold closing, thereby improving the injection molding quality of the automotive wire tube.

[0030] A runner plate 16 is disposed on the outer side of the fixed mold base 4 , and a gate 17 is disposed on the runner plate 16 .

[0031] A runner 18 is disposed inside the runner plate 16 , and the runner 18 is communicated with the gate 17 .

[0032] The cavity 12 of the movable mold base 3 , the cavity 12 of the fixed mold base 4 and the mold core 6 together form an injection cavity.

[0033] Among them, the overall injection molding equipment includes multiple groups of injection molding cavities. The melt enters the runner 18 through the gate 17, and is diverted by the runner 18 to guide the melt into each injection molding cavity respectively. The melt is cooled and solidified in the multiple groups of injection molding cavities. The overall injection molding equipment can process multiple groups of wire tube injection molded parts at one time, thereby improving the injection molding efficiency.

[0034] The first inclined surface 7 and the second inclined surface 8 have the same inclination. When the second inclined surface 8 of the core mold base 5 contacts the first inclined surface 7 of the movable mold base 3 , an extrusion force is applied to the first inclined surface 7 , so that the movable mold base 3 slides along the slide groove 11 .

[0035] Working principle: During injection molding, the cylinder 13 drives the core mold base 5 to move, and the core mold base 5 drives multiple sets of mold cores 6 to move synchronously. The core mold base 5 is driven by the cylinder 13 to move closer to the movable mold base 3 and the fixed mold base 4. The second inclined surface 8 of the core mold base 5 contacts the first inclined surface 7 of the movable mold base 3 and applies extrusion force to the first inclined surface 7, so that the movable mold base 3 slides along the slide groove 11, the spring 10 is stretched, and the movable mold base 3 moves closer to the fixed mold base 4. Figure 4 As shown, under the drive of the cylinder 13, the movable mold base 3, the fixed mold base 4 and the core mold base 5 are molded together, and the multiple sets of mold cores 6 of the core mold base 5 are embedded in the mold cavity 12 to form an injection cavity. The melt enters the runner 18 through the gate 17, and is diverted by the runner 18 to guide the melt to each injection cavity respectively. The melt is cooled and solidified in the multiple sets of injection cavities. After the wire tube injection molding is formed, the mold is opened. When the mold is opened, the cylinder 13 drives the core mold base 5 and the multiple sets of mold cores 6 to reset, and the external force applied to the first inclined surface 7 disappears. The movable mold base 3 slides and resets along the slide groove 11 under the action of the rebound force of the multiple sets of springs 10, as shown in FIG. Figure 3 As shown, the injection molding chamber is automatically separated, and the wire tube molded part is automatically demoulded and falls by its own gravity.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
