Description

Technical Field

[0001] This utility model relates to the field of injection mold angled ejector technology, and in particular to an embedded fixed mold angled ejector mechanism. Background Technology

[0002] Many existing molds use fixed mold angled ejectors to meet the product molding requirements. Generally, smaller products require fewer angled ejectors. If an integral fixed mold ejector plate is used, it will not be conducive to mold strength and cost control. The mold adopts an additional integral fixed mold ejector plate, which is not only time-consuming but also greatly increases the mold cost, and brings significant safety hazards to the mold operation. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose an embedded fixed mold inclined ejector mechanism to solve the problem of increased mold cost.

[0004] To achieve the above objectives, this utility model provides an embedded fixed mold inclined ejector mechanism, including a fixed template, a fixed mold groove on the end face of the fixed template, a fixed mold core contained in the fixed mold groove, a fixed mold inclined ejector slidably passing through the fixed mold core, the upper end of the fixed mold inclined ejector protruding from the fixed mold core and contacting the product undercut of the plastic product body, and an inclined ejector seat slidably connected to the lower end of the fixed mold inclined ejector, the inclined ejector seat being connected to the fixed template by a spring.

[0005] Optionally, the upper end of the fixed mold angled ejector is provided with an angled ejector groove that cooperates with the undercut of the product.

[0006] Optionally, the fixed mold groove is provided with a first placement groove to accommodate the inclined ejector seat, and the first placement groove is provided with a second placement groove to accommodate the spring.

[0007] Optionally, the fixed mold core has a bottom groove on the side facing the first placement groove for the movement of the inclined top seat.

[0008] Optionally, the fixed mold core is provided with a through hole for the fixed mold inclined ejector to pass through, and the slope of the fixed mold inclined ejector is the same as the slope of the through hole.

[0009] Optionally, the inclined ejector seat is provided with an inclined ejector groove, and the lower part of the fixed mold inclined ejector is provided with an inclined ejector slider that is slidably connected to the inclined ejector groove.

[0010] Optionally, the fixed mold core is provided with a through-hole, and a reset block connected to the inclined ejector is provided in the reset hole. The reset block is connected to the inclined ejector by screws.

[0011] Optionally, a limiting groove is provided on one side of the upper end of the reset hole, and a side protrusion is provided on the reset block to cooperate with the limiting groove.

[0012] The beneficial effects of this utility model are as follows: The embedded fixed mold inclined ejector mechanism provided by this utility model allows the spring to drive the inclined ejector seat to move upward when the mold opens. The inclined ejector seat drives the fixed mold inclined ejector to tilt and push the plastic product body. At the same time, due to the restriction of the fixed mold core on the fixed mold inclined ejector, the product undercut separates from the fixed mold inclined ejector in the horizontal direction, thus demolding the product undercut of the plastic product body. This inclined ejector mechanism embeds the fixed mold inclined ejector into the fixed mold and has a local slot in the mold. It is not only small in size but also easy to install, reducing mold costs, saving space, increasing mold strength, and making the mold operation safer and more reliable. Attached Figure Description

[0027] like Figures 1 to 10 As shown, an embedded fixed mold inclined ejector mechanism includes a fixed mold plate 1, a fixed mold groove 2 is provided on the end face of the fixed mold plate 1, a fixed mold core 3 is contained in the fixed mold groove 2, a fixed mold inclined ejector 9 is slidably disposed on the fixed mold core 3, the upper end of the fixed mold inclined ejector 9 protrudes from the fixed mold core 3 and contacts the product undercut 15 of the plastic product body 14, and an inclined ejector seat 6 is slidably connected to the lower end of the fixed mold inclined ejector 9, the inclined ejector seat 6 is connected to the fixed mold plate 1 by a spring 5.

[0028] Before the mold opens, the product undercut 15 contacts the upper end of the fixed mold inclined ejector 9. When the mold opens, the spring 5 drives the inclined ejector seat 6 to move upward. The inclined ejector seat 6 drives the fixed mold inclined ejector 9 to tilt and push the plastic product body 14. At the same time, due to the restriction of the fixed mold core 3 on the fixed mold inclined ejector 9, the product undercut 15 separates from the fixed mold inclined ejector 9 in the horizontal direction, so that the product undercut 15 of the plastic product body 14 is demolded. This inclined ejector mechanism embeds the fixed mold inclined ejector 9 into the fixed mold and makes a local groove in the mold. It is not only small in size but also easy to install, reducing mold cost, saving space, increasing mold strength, ensuring a certain strength of the mold, and making the mold operation safer and more reliable.

[0029] In addition, this inclined ejector mechanism can be used in hot runner molds when the hot runner plate is not moving.

[0030] The upper end of the fixed mold angled ejector 9 is provided with an angled ejector groove 10 that cooperates with the product undercut 15, so as to facilitate the demolding of the product undercut 15 by the fixed mold angled ejector 9 during subsequent mold opening.

[0031] The fixed mold groove 2 has a first placement groove 7 for accommodating the inclined ejector 6, and the first placement groove 7 has a second placement groove 8 for accommodating the spring 5, which facilitates the placement of the inclined ejector 6 and the spring 5.

[0032] The fixed mold core 3 has a bottom groove 16 on one side facing the first placement groove 7 for the movement of the inclined top seat 6. The bottom groove 16 provides space for the inclined top seat 6 to move upward.

[0033] The fixed mold core 3 has an inclined ejector hole 4 for the fixed mold inclined ejector 9 to pass through, and the slope of the fixed mold inclined ejector 9 is the same as the slope of the inclined ejector hole 4.

[0034] The inclined ejector seat 6 is provided with an inclined ejector groove 11, and the lower part of the fixed mold inclined ejector 9 is provided with an inclined ejector slider 12 that is slidably connected to the inclined ejector groove 11. When the fixed mold inclined ejector 9 is ejected upward, the inclined ejector seat 6 and the fixed mold inclined ejector 9 move towards each other, reducing the damage rate between the inclined ejector seat 6 and the fixed mold inclined ejector 9.

[0035] The fixed mold core 3 has a through-hole, and a reset block 13 connected to the inclined ejector seat 6 is provided in the reset hole. The reset block 13 is connected to the inclined ejector seat 6 by screws. The reset block 13 facilitates the reset of the fixed mold inclined ejector 9. The fixed mold core 3 is provided with a moving mold core and a moving template wrapped around the moving mold core. When the mold is closed, the moving mold core on the fixed mold core 3 presses the reset block 13 to reset the fixed mold inclined ejector 9.

[0036] A limiting groove is provided on one side of the upper end of the reset hole, and a side protrusion is provided on the reset block 13 to cooperate with the limiting groove, so as to facilitate the positioning and placement of the reset block 13.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0038] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
