Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a three-slider die casting mold for an EBS trailer control valve. Background Technology

[0002] The EBS trailer control valve is a key component of the electronic braking system, used for trailer braking control.

[0003] During the die-casting production of control valve bodies, a cold layer (a low-temperature area that accumulates on the mold surface due to frequent contact with high-temperature molten metal) can form on the mold surface, resulting in aluminum shavings on the barrel. During injection, the molten aluminum carries the aluminum shavings through the gate and into the molding cavity. After die-casting, the control valve needs to have its edges trimmed (usually by knocking off the shavings). However, after knocking off the shavings, workers discovered that the edges of the finished control valve had gaps, affecting the quality of the finished product and requiring improvement. Utility Model Content

[0004] To address the issue of potential gaps at the edges of finished control valves and improve their quality, this application provides a three-slider die-casting mold for EBS trailer control valves.

[0005] The technical solution provided in this application for a three-slider die-casting mold for an EBS trailer control valve is as follows: An EBS trailer control valve three-slider die-casting mold includes a fixed mold and a moving mold. A forming mold is mounted on the moving mold. The forming mold includes a main mold body disposed on the moving mold and an auxiliary mold body disposed on the main mold body. A forming cavity is formed on one side of the main mold body and the auxiliary mold body opposite to each other. A material cylinder is provided on the moving mold, and an injection port is provided inside the material cylinder. An injection channel is provided on the main mold body, and a gate is also provided on the main mold body. The injection channel connects the injection port and the gate. Two placeholder protrusions are provided inside the gate, and the placeholder protrusions are located at the connection between the gate and the forming cavity.

[0006] Preferably, the cross-section of the occupier protrusion is rhomboid.

[0007] Preferably, the molding die has a reinforcing rib slot located at the connection between the gate and the molding cavity.

[0008] Preferably, the main mold body is provided with sliders located at both ends of the extending direction of the molding cavity, and the moving mold is provided with a first hydraulic cylinder for driving the sliders to move away from each other.

[0009] Preferably, the main mold body is provided with a release module, which is located on one side of the extending direction of the molding cavity, and the moving mold is provided with a second hydraulic cylinder for driving the release module away from the molding cavity.

[0010] Preferably, the main mold body is provided with an exhaust channel, and the exhaust channel is provided with a first slag bag, which is connected to the molding cavity; the main mold body is provided with an exhaust component, which is used for exhausting air and is connected to the exhaust channel.

[0011] Preferably, the main mold body is provided with a second slag bag, the second slag bag is connected to the molding cavity, and the second slag bag is located at both ends of the extending direction of the molding cavity.

[0012] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model adds two spacer protrusions at the gate to create two holes between the body of the molded part of the control valve body and the material handle on its outer side. When the material handle is knocked, these two holes can disperse the force on the edge of the molded part, allowing the material handle to be knocked off smoothly. The ends of the material handle and the edge of the molded part are smooth, thereby improving the problem of gaps that may appear on the edge of the finished control valve and improving the quality of the control valve. 2. This utility model further ensures that the edge of the molded part remains smooth after cutting by setting the shape of the occupant protrusion to a rhombus shape, thereby reducing the occurrence of gaps on the edge; 3. This utility model improves the strength of the finished control valve by setting a reinforcing rib slot so that the outer wall of the molded part will have a reinforcing rib structure after molding.

[0020] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0021] This application discloses a three-slider die-casting mold for an EBS trailer control valve.

[0022] Reference Figure 1 The EBS trailer control valve three-slider die-casting mold of this embodiment includes a fixed mold 1 and a moving mold 2.

[0023] Reference Figure 2 and Figure 3 A forming mold 3 is installed on the moving mold 2. The forming mold 3 includes a main mold body 31 (not shown in the figure) fixed on the moving mold 2 and an auxiliary mold body 32 fixed on the main mold body 31. A forming cavity 4 is opened on the opposite side of the main mold body 31 and the auxiliary mold body 32.

[0024] Reference Figure 4 and Figure 5 A material cylinder 5 is fixed on the moving mold 2, and a sprue 6 is provided inside the material cylinder 5. A sprue channel 7 is provided on the main mold body 31, and a gate 8 is also provided on the main mold body 31. The sprue channel 7 connects the sprue 6 and the gate 8. Two placeholder protrusions 9 are fixed inside the gate 8, and the placeholder protrusions 9 are located at the connection between the gate 8 and the molding cavity 4. The cross-section of the placeholder protrusions 9 is rhomboid.

[0025] Reference Figure 4 and Figure 5 The molding die 3 has a reinforcing rib slot 10 located at the connection between the gate 8 and the molding cavity 4. The reinforcing rib slot 10 can add a layer of reinforcing ribs to the edge of the molded part to improve the strength of the control valve body.

The slider 11 is located at both ends in the extension direction of the molding cavity 4 (i.e., the length direction of the product 19). A first hydraulic cylinder 12 is fixed on the moving mold 2 to drive the slider 11 away from each other (see...). Figure 1A release module 13 is mounted on the main mold body 31. The release module 13 is located on one side of the extending direction of the molding cavity 4. A second hydraulic cylinder 14 is fixed on the moving mold 2 to drive the release module 13 away from the molding cavity 4 (see...). Figure 1 The first hydraulic cylinder 12 moves the slider 11 to pull the core, and the second hydraulic cylinder 14 moves the detachment module 13 to pull the core (product 19 also has two small holes on one side, see [reference]). Figure 6 This facilitates the demolding of subsequent molded parts.
