Description

Technical Field

[0001] This utility model relates to the field of molding compound production equipment, specifically to a mold venting and sealing device. Background Technology

[0002] In current BMC molding compounds, some products feature a central circular hole design. However, during actual production, these holes, which should have remained open, are instead sealed due to material intrusion, resulting in the holes in the finished product not being in the intended open state.

[0003] Therefore, there is an urgent need to develop a new structural design to solve this problem and improve the product qualification rate. Summary of the Invention

[0004] This utility model aims to provide a mold venting and sealing device, the specific solution of which is as follows:

[0005] A mold venting and sealing device includes an upper mold frame, a lower mold frame, and a product. A mold mounting assembly is provided between the upper mold frame and the lower mold frame. The mold mounting assembly includes an upper mold cavity, which is mounted on the upper mold frame. A mounting base is fixedly mounted on the upper mold cavity, and an elastic body is provided inside the mounting base. An insert upper fixing block is slidably disposed inside the upper mold cavity. The insert upper fixing block and the elastic body are configured to cooperate. The product includes a central opening, which is configured to cooperate with the insert upper fixing block.

[0006] An insert is provided inside the opening. In practice, the elastic body drives the fixing block on the insert to move downward in the upper mold cavity and always fits against the upper surface of the insert, so that the material will not flow onto the upper surface of the insert, and therefore there will be no situation where the circular hole is closed.

[0007] The other side of the insert is provided with a lower fixing block, which is set on the lower mold cavity. The lower mold frame is provided with a lower mold cavity.

[0008] The mold mounting components are several.

[0009] The upper model cavity is provided with a groove, and the lower model cavity is provided with a protrusion. The groove and the protrusion are configured to cooperate.

[0010] This utility model discloses a mold venting and sealing device. The mounting base is fixed on the upper mold cavity, and the elastic body is compressible. When the mold is closed, the elastic body is in a compressed state. When venting, the upper and lower molds separate, and the elastic body drives the fixing block on the insert to move downward in the upper mold cavity, so that the material does not flow into the round hole, thereby avoiding the situation of the round hole being closed.

[0017] The following is combined with Figure 1-5 Further explanation:

[0018] A mold venting and sealing device includes an upper mold frame 1, a lower mold frame 10, and a product 6. A mold mounting assembly 11 is provided between the upper mold frame 1 and the lower mold frame 10. The mold mounting assembly 11 includes an upper mold cavity 2, which is mounted on the upper mold frame 1. A mounting base 3 is fixedly mounted on the upper mold cavity 2, and an elastic body 4 is provided inside the mounting base 3. An insert upper fixing block 5 is slidably disposed inside the upper mold cavity 2, and the insert upper fixing block 5 and the elastic body 4 are configured to cooperate. The product includes a central opening, and the central opening and the insert upper fixing block 5 are configured to cooperate. An insert 7 is provided inside the opening. An insert lower fixing block 8 is provided on the other side of the insert 7, and the insert lower fixing block 8 is disposed on the lower mold cavity 9. The lower mold frame 10 has a lower mold cavity 9. There are several mold mounting assemblies 2 (two are shown in the figure). The upper mold cavity 2 has a groove 12, and the lower mold cavity 10 has a protrusion 13, and the groove 12 and the protrusion 13 are configured to cooperate. Figure 3 (The image in the middle is for illustrative purposes only; in reality, each element is set up in a specific way.)

[0019] This utility model discloses a mold venting and sealing device. The mounting base 3 is fixed on the upper mold cavity 2, and the elastic body 4 is compressible. When the mold is closed, the elastic body 4 is in a compressed state. When venting, the upper and lower molds (i.e., the upper mold frame 1 and the lower mold frame 10) will separate. The elastic body 4 will drive the fixing block 5 on the insert to move downward in the upper mold cavity 2 and always stick to the upper surface of the insert 7, so that the material will not flow onto the upper surface of the insert 7. Therefore, the round hole of the final product will not be closed. The working principle of the upper mold frame 1 and the lower mold frame 10 is the prior art and will not be described in detail.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
