Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a mold structure for a direct-drive inclined-ejector motion. Background Technology

[0002] The main function of the angled ejector pin in an injection mold is to help the plastic part be demolded from the mold, especially when the plastic part has sidewalls or complex geometry. The tilting movement of the angled ejector pin ensures that the plastic part is smoothly removed from the mold, preventing tearing or breakage.

[0003] When plastic parts have complex structures or inverted designs, using a slanted ejector rod to push the product out can easily cause the slanted ejector rod to move backward and interfere with the product, affecting the smooth removal of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a direct-drive inclined ejector mold structure to solve the problem of interference between the inclined ejector and the product during product demolding in injection molds.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a direct-drive inclined-ejector motion mold structure, comprising:

[0006] A movable template, on which a core is provided;

[0007] A straight ejector rod is fixedly mounted at its bottom on an ejector plate, and a straight ejector head is provided at the top of the straight ejector rod, which passes through the core.

[0008] The inclined ejector rod has an inclined ejector head at its top, which contacts the straight ejector head. Symmetrically arranged guide grooves are provided on both sides of the inclined ejector head. The inclined ejector head is slidably connected to the core. The inclined ejector rod passes through the moving template and is slidably connected to the ejector plate at its bottom.

[0009] As a further description of the above technical solution:

[0010] The bottom of the inclined push rod is provided with a connecting seat, and the connecting seat is provided with a rotatable sliding plate. The sliding plate is slidably connected to the base, and the base is fixedly installed on the push pin plate.

[0011] As a further description of the above technical solution:

[0012] The base has a sliding groove on its side wall, and the sliding plate is slidably connected in the sliding groove.

[0013] As a further description of the above technical solution:

[0014] The thickness of the sliding plate is greater than or equal to the depth of the groove.

[0015] As a further description of the above technical solution:

[0016] The connecting seat has symmetrically arranged sliding plates on both sides.

[0017] As a further description of the above technical solution:

[0018] The sliding plate is a self-lubricating wear-resistant block.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, after injection molding is completed, the mold opens, and the product on the core surface of the moving mold plate is ejected via straight ejector pins and angled ejector pins. Specifically, during ejection, the ejector plate moves upward, the straight ejector pins lift the product upward through their straight ejector heads, and simultaneously, because the bottom of the angled ejector pin is slidably connected to the ejector plate, it achieves horizontal sliding. The angled ejector head at the top of the angled ejector pin moves upward while simultaneously retracting to detach from the product, thus achieving product demolding. The straight ejector pins directly drive the product to detach from the core, and combined with the synchronized angled ejector pin movement, effectively solves the problem of interference between the overall backward movement of the angled ejector pins and the product during product demolding in injection molds.

[0021] 2. In this utility model, the sliding plate on the bottom connecting seat of the inclined push rod slides within the base, realizing the relative sliding between the inclined push rod and the ejector plate. The groove effectively restricts the relative position change between the inclined push rod and the base in the vertical direction, effectively positioning the inclined push rod.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-5 This utility model provides a technical solution: a direct-drive inclined-ejector motion mold structure, comprising:

[0033] Movable template 1, on which a core 11 is provided;

[0034] The bottom of the straight push rod 2 is fixedly installed on the ejector plate 9, and the top of the straight push rod 2 is provided with a straight push head 21, which passes through the core 11.

[0035] The inclined push rod 3 has an inclined push head 31 at its top, which contacts the straight push head 21. The inclined push head 31 has symmetrically arranged guide grooves 311 on both sides. The inclined push head 31 is slidably connected to the core 11. The core 11 has a protrusion that extends into the guide groove 311 to achieve relative sliding with the inclined push head 31. The inclined push rod 3 passes through the moving template 1 and is slidably connected to the ejector plate 9 at its bottom.

[0036] The bottom of the inclined ejector rod 3 is provided with a connecting seat 32, and a rotatable sliding plate 321 is provided on the connecting seat 32. The sliding plate 321 is slidably connected to the base 33, and the base 33 is fixedly installed on the ejector plate 9. The sliding plate 321 on the connecting seat 32 at the bottom of the inclined ejector rod 3 slides within the base 33, realizing the relative sliding between the inclined ejector rod 3 and the ejector plate 9.

[0037] Working Principle: After injection molding, the mold opens, and the product 8 on the surface of the core 11 on the moving platen 1 is ejected through the straight ejector pin 2 and the angled ejector pin 3. Specifically, during ejection, the ejector plate 9 moves upward, and the straight ejector pin 2 lifts the product 8 upward through the straight ejector head 21. Simultaneously, because the bottom of the angled ejector pin 3 is slidably connected to the ejector plate 9, it slides horizontally. The angled ejector head 31 at the top of the angled ejector pin 3 moves upward while simultaneously retracting to detach from the product 8, thus achieving product demolding. The straight ejector pin 2 directly drives the product 8 to detach from the core 11, and combined with the synchronized angled ejector pin 3, effectively solves the problem of interference between the overall backward movement of the angled ejector pins and the product during product demolding in injection molds.

[0038] Example 2

[0039] Based on the above embodiments, this embodiment further improves upon the following technical solution: a groove 331 is provided on the side wall of the base 33, a sliding plate 321 is slidably connected in the groove 331, and the thickness of the sliding plate 321 is greater than or equal to the depth of the groove 331.

[0040] The groove 331 effectively restricts the relative position change between the inclined push rod 3 and the base 33 in the vertical direction, and effectively positions the inclined push rod 3.

[0041] Example 3

[0042] Based on the above embodiments, this embodiment further improves upon the following technical solution: symmetrically arranged sliding plates 321 are provided on both sides of the connecting seat 32 to effectively ensure the smooth sliding of the inclined push rod 3.

[0043] The sliding plate 321 can be made of self-lubricating wear-resistant blocks to effectively prevent the inclined push rod 3 from getting stuck during the sliding process.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
