Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to an upper mold including a slanted pull structure. Background Technology

[0002] like Figure 1 As shown, the product has a complex structure with a prominent slot on its upper surface that faces to the left or right. To meet the production requirements of such products, the mold demolding structure usually adopts an upper mold inclined ejector structure. However, the upper mold inclined ejector structure requires a large space for the mold, the inclined ejector is not strong enough and is easily damaged, and the upper mold is easy to deform, resulting in high manufacturing costs and failing to meet production requirements.

[0003] Therefore, there is an urgent need for an upper mold with a slanted pull structure that has strong structural stability, is simple to manufacture, easy to install, and meets production requirements. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a mold upper mold oblique pulling structure, which aims to allow the upper mold buckle to retract first, thus preventing the buckle from sticking to the mold core.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A type of upper mold with a slanted pull structure includes a panel, an A-plate, an upper mold core, and a slanted pull structure. The panel is disposed on the upper side of the A-plate, and the upper mold core is disposed inside the A-plate. The slanted pull structure includes a shovel, an upper mold insert, an upper mold insert guide block, and pressure strips. The shovel is connected to the panel, and the upper mold insert is disposed on the lower side of the upper mold insert guide block. The shovel and the upper mold insert guide block have mutually compatible inclined surfaces. The pressure strips are a pair and are horizontally disposed on the A-plate. When the shovel moves upward, the upper mold insert guide block drives the upper mold insert to move horizontally towards the shovel under the action of the upper limit of the pressure strips.

[0006] Furthermore, the shovel is provided with a shovel inclined surface, and a T-shaped shovel base guide block is provided on the shovel inclined surface. The upper mold insert guide block is provided with an upper mold insert guide block inclined surface that is compatible with the shovel inclined surface. The upper mold insert guide block inclined surface is provided with a T-shaped guide rail groove that is compatible with the T-shaped shovel base guide block. The shovel base guide block slides up and down along the guide rail groove.

[0007] Furthermore, the inclination angle of the shovel inclined surface and the upper mold insert guide block inclined surface is 30° to 60°.

[0008] Furthermore, the inclination angle of the shovel inclined surface and the upper mold insert guide block inclined surface is 45°.

[0009] Furthermore, the upper mold insert guide block has a guide block protrusion on the contact surface with the pressure strip, and the pressure strip is positioned above the guide block protrusion.

[0010] Furthermore, it also includes a limiting screw, which connects the panel and plate A to limit the travel of the panel.

[0011] Furthermore, the upper mold insert is connected to the upper mold insert guide block via a pin.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses an upper mold with a slanted pull structure. The slanted pull structure solves the problem of difficult demolding of products on the upper mold, avoids sticking to the mold core due to the snap-fit, and effectively ensures normal and safe demolding of the product. The structure is simple and stable, easy to manufacture and install, and allows for smooth and stable production. At the same time, the stability of the structure also reduces the number of mold repairs during production, saves costs, and is easy to promote. Attached Figure Description

[0018] The specific embodiments of this utility model will be further explained below with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, an upper mold with a slanted pull structure is provided, including a panel (1), an A plate (2), an upper mold core (3), a slanted pull structure, and a limiting screw (11).

[0020] The panel (1) is located on the upper side of plate A (2), and the limiting screw (11) connects the panel (1) and plate A (2) to limit the stroke of the panel (1) as it extends out of plate A (2). The upper mold core (3) is located inside plate A (2), and the inclined pull structure is located between the panel (1), plate A (2), and upper mold core (3).

[0021] The inclined pulling structure includes a shovel (5), a shovel base guide block (6), an upper mold insert (7), an upper mold insert guide block (9), a pressure strip (10), and a pin (8). The shovel (5) is fixedly connected to the panel (1) by screws. The panel (1) drives the shovel (5) to move up and down synchronously. The shovel 5 is provided with a shovel inclined surface. The shovel inclined surface is provided with a T-shaped shovel base guide block (6). The upper mold insert (7) is connected and fixed to the upper mold insert guide block (9) by a pin (8). The upper mold insert (7) is provided with a buckle 7-1 that matches the slot 4-1 of the side opening on the upper end face of the product. The upper mold insert guide block (9) is provided with an upper mold insert guide block inclined surface that matches the shovel inclined surface. The upper mold insert guide block inclined surface is provided with a T-shaped guide rail groove that matches the T-shaped shovel base guide block (6). The shovel base guide block (6) can slide up and down along the guide rail groove.

[0022] The inclination angle of the two inclined planes is 30° to 60°, with 45° being the optimal angle. The inclination direction is towards the lateral opening of the slot on the upper surface of the product.

[0023] A pair of pressure strips (10) are horizontally arranged on the A plate (2). The shovel (5) and the matching upper mold insert guide block (9) are located between the two pressure strips (10). The upper mold insert guide block (9) has a guide block protrusion on the contact surface with the pressure strips (10) on both sides. The pressure strip (10) is set above the guide block protrusion as the upper limit position for the upper mold insert guide block (9) to move upward.

[0024] The purpose of this setup is that, during mold opening, the panel (1) drives the shovel (5) to move upward, making it easier to pull out the bottom slot feature first, leaving space for the movement of the slider insert without interference. The shovel (5) simultaneously drives the shovel base guide block (6) to slide upward in the guide rail groove. Due to the mutual friction between the shovel 5 and the upper mold insert guide block (9), while the shovel base guide block (6) slides upward along the guide rail groove, the upper mold insert guide block (9), under the upper limit action of the pressure strip (10), drives the upper mold insert (7) to move synchronously towards the lateral opening direction of the slot 4-1 on the upper end face of the product 4, thereby causing the buckle 7-1 on the upper mold insert (7) to disengage from the slot 4-1 of the product, achieving buckle withdrawal and smooth demolding. Figure 2 As shown.

[0025] The inclined pull structure of this embodiment is simple, easy to manufacture, low in cost, easy to install, and stable in structure. It can effectively ensure the normal and safe demolding of products and smooth and stable production, and can be widely promoted and applied.

[0026] It should be noted that the product is placed on the surface of the lower mold. Since this embodiment is only a technical improvement on the upper mold, the specific structure of the lower mold will not be described in this embodiment.

[0027] Finally, it should be noted that 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 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. However, 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.
