Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a side core-pulling and inlaying structure of a slide block for thin-walled products. Background Art
[0002] Thin-walled products refer to products with a wall thickness of less than 1mm. Their lightness, transparency and softness make them widely used in food packaging, medical equipment, daily necessities and other fields. Thin-walled parts are widely used due to their light weight, compact structure and material saving. Therefore, molds for producing corresponding thin-walled products are particularly important.
[0003] Existing thin-walled products are thin and have poor rigidity. In particular, traditional molds have poor venting during injection molding and unstable docking between the upper and lower molds. Thin-walled products are prone to burrs and rough edges, which affects the production quality of thin-walled products. In addition, traditional molds are inconvenient to replace, which means that the molds can only produce specific types of thin-walled products, resulting in certain limitations in the use of the device. Utility Model Content

[0006] A side core-pulling inlay structure for a thin-walled product slider comprises a fixed base and an upper mold, a molding device is inserted and fixedly installed on the right end of the fixed base, docking inserts are fixedly installed on the upper left and upper right parts of the fixed base, positioning plates are fixedly installed on the upper front and upper rear parts of the fixed base, an injection port is installed on the middle part of the upper end of the upper mold, two exhaust holes are opened on the upper left and upper right parts of the upper mold, and a connecting device is installed jointly on the left end of the fixed base and the left end of the upper mold.
[0007] Preferably, the molding device includes a lower mold, an injection molding cavity is formed at the upper end of the lower mold, a connecting seat is fixedly installed at the right end of the lower mold, screw holes are formed at the front and rear ends of the connecting seat, fixing screws are installed at the front right part and the rear right part of the fixed base, a mounting groove is formed at the right end of the fixed base, and the lower mold is fixed in the mounting groove by fixing screws. By loosening the fixing screws, the connecting seat is pulled, and the connecting seat drives the lower mold to be pulled out of the mounting groove on the fixed base. At this time, the lower mold of the corresponding model can be reinstalled in the fixed base, so that the lower mold can be replaced as needed.
[0008] Preferably, the upper mold has a No. 1 docking groove at the left and right parts of the lower end, and a No. 2 docking groove at the front and rear parts of the lower end. The No. 1 docking groove on the upper mold docks with the docking insert, and the No. 2 docking groove docks with the positioning plate, so that the upper mold and the lower mold can be fixed with multiple limits when the mold is closed, thereby improving the stability during the mold closing.
[0009] Preferably, the connecting device comprises an upper mounting seat and a lower mounting seat, wherein two positioning columns are fixedly mounted on the lower end of the upper mounting seat, the upper mounting seat is fixedly mounted on the left end of the upper mold, and two positioning holes are formed on the upper end of the lower mounting seat, and the lower mounting seat is fixedly mounted on the left end of the fixed base.

[0010] Preferably, the docking insert is semi-trapezoidal in shape.
[0011] Preferably, the positioning column and the positioning hole have the same size and are located in corresponding positions.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The positioning column on the connecting device slides up and down in the positioning hole on the lower mounting seat, thereby ensuring that the upper mounting seat and the lower mounting seat can slide in opposite directions, so that the upper mold and the lower mold can be initially guided when the mold is closed. Then the No. 1 docking groove on the upper mold is docked with the docking insert, and the No. 2 docking groove is docked with the positioning plate, so that the upper mold and the lower mold can be fixed with multiple limits when the mold is closed, which improves the stability when the mold is closed. In addition, when the upper mold injects the material into the injection cavity on the lower mold through the injection port, the material fills the inside of the injection cavity, and the air in the upper part of the injection cavity is discharged through multiple exhaust holes, thereby avoiding bubbles in the product and improving the production quality of the device.
[0014] 2. When the device needs to produce thin-walled products of different models, the fixing screws are loosened and the connecting seat is pulled, which in turn drives the lower mold to be pulled out of the installation groove on the fixed base. At this time, the lower mold of the corresponding model can be reinstalled into the fixed base, so that the lower mold can be replaced as needed, thereby improving the practicality of the device.
