Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a quick demoulding mold for a cover body. Background Art

[0002] Special-shaped structural parts such as cover bodies are usually formed by injection molding. In the injection molding process, the demolding efficiency of the mold directly affects the production efficiency of the product. In the existing injection molding production process, the demolding of injection molded parts is usually done manually. However, since the surface of the injection molded parts still has a relatively high temperature after molding, adsorption and adhesion occur between the injection molded parts and the mold core and mold core. They cannot be removed quickly by manpower, resulting in a long demolding time, which makes it difficult to meet the needs of high-efficiency production.

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick demoulding mold for a cover body proposed by the utility model comprises a front mold 1 and a rear mold 2 fixed on a base and connected to the front mold 1, a front mold core 11 is provided at the bottom of the front mold 1, a rear mold core 201 is provided on the top surface of the rear mold 2, a sliding channel 6 is provided at the side end between the front mold 1 and the rear mold 2, a slider 7 is slidably connected in the sliding channel 6, a movable mold core 8 is connected to the front end of the slider 7, an oil cylinder 5 is installed at one end of the rear mold 2 located on the outer side of the sliding channel 6 through a bracket 3, an output end of the oil cylinder 5 is drivingly connected to the slider 7, and the front mold core 11, the rear mold core 201 and the movable mold core 8 cooperate to form a molding cavity 9 for injection molding.

[0021] Furthermore, a pouring channel 12 is provided on the front mold 1, and a flow channel 10 is provided between the front mold core 11 and the rear mold core 201, one end of the flow channel 10 is connected to the pouring channel 12, and the other end is connected to the molding cavity 9.

[0022] Furthermore, a sprue sleeve 1201 is provided on the top of the front mold 1, and the sprue sleeve 1201 is connected to the pouring channel 12, and the sprue sleeve 1201 is connected to the injection port of the injection molding machine, so that the molten plastic flows into the mold evenly and stably through the pouring channel 12.

[0023] Furthermore, a connecting plate 701 is provided at one end of the slider 7 away from the movable mold core 8. The connecting plate 701 has a connecting hole. Bolts are provided in the connecting hole. The bolts pass through the connecting plate 701 and the slider 7 in sequence and are connected to the movable mold core 8.

[0024] Furthermore, a through hole is provided in the middle of the connecting plate 701 , and the output end of the oil cylinder 5 passes through the bracket 3 and the through hole of the connecting plate 701 and is connected to the slider 7 through threads.

[0025] Furthermore, a fixing plate 4 is provided on the bracket 3 , and the oil cylinder 5 is mounted on the bracket 3 through the fixing plate 4 , so as to ensure the stability of the oil cylinder 5 during operation.

[0026] Furthermore, the front mold 1 is located on one side of the top wall of the sliding channel 6 and is connected to a limit pin 101 by bolts. A notch groove 702 corresponding to the limit pin 101 is provided on the top wall on the corresponding side of the sliding block 7 for limiting the sliding block 7.

[0027] The working principle of the high-precision positioning surface grinder based on Example 1 is: before injection molding, the front mold 1 and the rear mold 2 are in a closed connection state, the front mold core 11 at the bottom of the front mold 1 and the rear mold core 201 on the top surface of the rear mold 2 are combined and connected to form the outer contour of the cover body injection molded part, and the surface of the movable mold core 8 is the inner contour of the cover body injection molded part. The oil cylinder 5 drives the slider 7 to drive the movable mold core 8 to move along the sliding channel 6 toward the front mold core 11 and the rear mold core 201, so that the front mold core 11, the rear mold core 201 and the movable mold core 8 cooperate with each other to form a molding cavity 9 for injection molding of the cover body.

[0028] During injection molding, the injection molding machine squeezes the molten plastic into the mold through the pouring channel 12 on the front mold 1, and flows into the molding cavity 9 along the runner 10 to form the desired shape of the cover product. After molding, it needs to be taken out of the mold, and the front mold 1 is separated from the rear mold 2 under the drive of the injection molding machine, so that the front mold core 11 is separated from the molded cover body, and the cylinder 5 starts to work, and its output end drives the slider 7 to contract, so that the slider 7 drives the movable mold core 8 to slide toward the outer end of the sliding channel 6, so that the movable mold core 8 is partially automatically separated from the molded cover body. At this time, the front mold core 11 and the movable mold core 8 are both separated from the cover body, so that the surface of the cover body can be quickly cooled, and the cover body is only connected to the rear mold core 201, and the injection molding operator can easily remove it, thereby achieving rapid demolding.
