Description

Technical Field

[0001] This utility model relates to an injection mold structure, and more particularly to a front mold inclined ejector sliding mechanism for an injection mold. The front mold inclined ejector mechanism and the sliding mechanism work together to solve the design and production problems of injection molds for connecting plate-type injection molded products, such as simultaneous demolding in both left and right directions. Background Technology

[0002] Injection molded products, such as connecting plates, are often designed with structures that connect to other components. If the product has left-hand and right-hand fasteners, the demolding mechanism of the injection mold must be designed to demold to the left and right sides of the product. The demolding mechanism to the left and right sides of the product must take into account the feasibility of its movement and the interference between the moving parts and other internal parts of the injection mold. Utility Model Content

[0003] This utility model addresses the aforementioned technical challenges by providing a front mold inclined ejector sliding mechanism for an injection mold, comprising a front mold base plate, a front template plate, a rear template plate, a front mold core, a rear mold core, an inclined ejector limiting seat, an inclined ejector pull rod, a front mold inclined ejector, an inclined ejector rod, an inclined ejector rod seat, a sliding seat, a guide block, a limiting block, a return spring, an inclined ejector pull block, a horizontal sliding mechanism, an injection molded product, and a spring guide rod. The injection molded product is a connecting plate-type component, and its right end is designed with left-hand and right-hand fasteners for connecting other components. The front mold core, rear mold core, and... The front mold angled ejector and horizontal slide form the injection cavity of the injection molded product when the injection mold is closed. In the closed state, the front mold plate is fixedly mounted on the front mold base plate, the front mold core is fixedly mounted on the front mold plate, and the rear mold core is fixedly mounted on the rear mold plate. The upper surface of the rear mold plate contacts the lower surface of the front mold plate and is flush with the four end faces of the front mold plate. The angled ejector limit seat is fixedly mounted on the front mold plate, and the angled ejector tie rod passes through the angled ejector limit seat and is fixedly mounted on the front mold angled ejector. The angled ejector tie rod can move along the angled stepped through-hole on the angled ejector limit seat. The return spring is pre-compressed and installed in the inclined cylindrical hole on the inclined ejector limit seat. The spring guide rod passes through the inner hole of the return spring and is fixedly installed on the front mold inclined ejector. The front mold inclined ejector can move obliquely up and down along the inclined square hole on the front mold core, which is the same size as the front mold inclined ejector. The inclined ejector pull block is fixedly installed on the rear mold core. The T-shaped structure at the bottom of the front mold inclined ejector is fitted into the T-slot formed by the inclined ejector pull block and the rear mold core and can slide horizontally left and right along the T-slot. The inclined ejector rod seat is fixedly installed on the front template, and the inclined ejector rod is fixed. The inclined rod is installed in the inclined cylindrical hole of the same size as the inclined rod base. The bottom of the inclined rod is installed in the inclined cylindrical hole of the same size as the horizontal slide and can move obliquely up and down along the inclined cylindrical hole. The guide block is fixedly installed on the rear template. The guide block and the rear template are assembled into a T-slot structure. The T-shaped structure at the bottom of the horizontal slide is fitted into the T-slot formed by the guide block and the rear template and can slide horizontally left and right along the T-slot. The limit block is fixedly installed on the rear template and the horizontal slide is fixedly installed on the slide base.

[0004] The beneficial effects of this utility model are as follows: the front mold inclined ejector sliding mechanism of the injection mold, through the cooperation of the front mold inclined ejector mechanism and the sliding mechanism, realizes the demolding of the connecting plate type injection molded products in both left and right directions after injection molding, thereby improving the mass production capability of the injection mold.

Horizontal slide; 17. Injection molded product; 18. Spring guide rod. Detailed Implementation

[0014] As attached Figures 1-8 As shown, a front mold inclined ejector sliding mechanism for an injection mold includes a front mold base plate 1, a front template 2, a rear template 3, a front mold core 4, a rear mold core 5, an inclined ejector limiting seat 6, an inclined ejector pull rod 7, a front mold inclined ejector 8, an inclined ejector rod 9, an inclined ejector rod seat 10, a sliding seat 11, a guide block 12, a limiting block 13, a return spring 14, an inclined ejector pull block 15, a horizontal sliding mechanism 16, an injection molded product 17, and a spring guide rod 18.

[0015] As attached Figure 8 As shown, injection molded product 17 is a connecting plate type component. Injection molded product 17 has fasteners in both left and right directions. When demolding is completed after injection molding, the mold mechanism needs to complete demolding actions in both directions.

[0016] As attached Figures 1-7The images show the state of the mold mechanism when the injection mold is closed and the injection is complete. After the injection molded product 17 is molded, the front mold base plate 1, front mold plate 2, front mold core 4, and inclined ejector limit seat 6 move upward relative to the rear mold plate 3. The front mold plate 2 drives the inclined ejector rod seat 10 and the inclined ejector rod 9 to move upward. The inclined ejector rod 9 drives the slide seat 11 and the horizontal slide 16 to slide horizontally to the right along the T-slot formed by the guide block 12 and the rear mold plate 3. The left side structure of the horizontal slide 16 disengages from the right-side locking mechanism at the right end of the injection molded product 17. When the front mold base plate 1, front mold plate 2, front mold core 4, and inclined ejector limit seat 6 move upward relative to the rear mold plate 3, the positions of the injection molded product 17 and the rear mold core 5 remain unchanged. The pressure of the pre-compressed reset spring 14 is released, pressing the front mold inclined ejector 8 downward. The T-slot formed by the inclined ejector pull block 15 and the rear mold core 5 restricts the movement of the front mold inclined ejector 8 in the vertical direction. Relative to the downward movement of the front mold core 4, the bottom end face of the front mold ejector 8 slides horizontally to the left along the upper surface of the rear mold core 5 and the injection molded product 17. The bottom locking structure of the front mold ejector 8 disengages horizontally to the left from the injection molded product 17, and the bottom T-shaped structure of the front mold ejector 8 disengages from the T-shaped groove formed by the ejector pull block 15 and the rear mold core 5. The top stepped surface of the ejector pull rod 7 contacts the stepped hole shoulder surface of the ejector limit seat 6. At this time, the injection molded product 17 moves in both left and right directions. The locking structure is demolded by the front mold inclined ejector mechanism and the sliding structure respectively; the front mold base plate 1 and the front mold plate 2 continue to move upward, driving the front mold core 3, the inclined ejector limit seat 6, the inclined ejector tie rod 7, the front mold inclined ejector 8, the spring guide rod 18, the return spring 14, the inclined ejector rod 9 and the inclined ejector rod seat 10 to move upward. The bottom rod of the inclined ejector rod 9 disengages from the sliding seat 11, and the right side of the sliding seat 11 contacts the left side of the limit block 13, thus completing one cycle of injection molding production.

[0017] A sliding mechanism for the front mold of an injection mold achieves demolding in both left and right directions by coordinating the movement of the front mold inclined ejector mechanism and the sliding mechanism.

[0018] The above description is a preferred embodiment of the present utility model and is intended to illustrate the content and concept of the present utility model. The content of this specification should not be construed as a limitation of the present utility model.
