Technical Field

[0001] The utility model belongs to the field of molds, in particular to a mold inclined ejector pin structure. Background Art

[0002] Nowadays, product structures are becoming more and more diversified, and local product structures are complex. For plastic products with a deeper product structure in the direction of the sloping top demoulding, there is a risk that the product will stick to the sloping top during demoulding, making it difficult to demould. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a mold inclined ejector pin structure with scientific design and reasonable structure, which is suitable for plastic products with a deeper product structure in the inclined ejector demoulding direction.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A mold inclined ejector pin structure is installed on the movable mold side of the mold assembly. The mold assembly includes a movable mold side and a static mold side that can move relatively open and close. The movable mold side can open or close the mold relative to the static mold side.

[0006] The moving mold core is fixedly mounted on the moving mold side, a processing mold cavity is arranged on one side of the moving mold core, a core oblique hole obliquely penetrating the moving mold core is arranged in the moving mold core, and the core oblique hole is arranged obliquely with respect to the mold opening direction;

[0007] The inclined ejector rod passes through the core inclined hole of the moving mold core, and one end of the inclined ejector rod away from the processing cavity is guided and connected in the ejector panel.

The inclined ejector rod can reciprocate along the limit track, and the guiding direction of the limit track is perpendicular to the mold opening direction.

[0008] The ejector assembly is installed in one end of the inclined ejector rod close to the processing cavity. The ejector assembly includes an ejector fixing plate and a spring. An ejector fixing plate is slidably connected in the groove at the end of the inclined ejector rod. A spring is abutted between the ejector fixing plate and the bottom of the groove. The spring maintains a preload force to push the ejector fixing plate outward. The end face of the ejector fixing plate is provided with an inclined guide surface that can cooperate with the inclined hole of the core.

[0009] Moreover, the angle between the core inclined hole and the mold opening direction is 15°-30°.

[0010] Moreover, the ejector panel is externally connected to an oil cylinder, an air cylinder or a telescopic rod driving structure to move toward or away from the dynamic model core.

[0011] Moreover, a through hole perpendicular to the mold opening direction is arranged in the inclined ejector rod, a bolt is slidably installed in the through hole, one end of the bolt cap is fixed in the ejector fixing plate through a hexagonal screw plug, and the stud part of the bolt is coaxially arranged in the through hole.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0023] See attached Figures 1 to 6 As shown,

[0024] This structure is installed on the movable mold side of the mold assembly. The mold assembly includes a movable mold side and a static mold side that can open and close relative to each other. The movable mold side can move up and down relative to the static mold side. The movable mold side and the static mold side are the same as the conventional mold structure. Other structures of the movable mold side and the static mold side are not shown in the attached drawings.

[0025] The moving model core 3 is fixed on the moving model side, and a processing cavity is arranged on one side of the moving model core 3. A core inclined hole 31 which is inclined and passes through the moving model core 3 is arranged in the moving model core 3. The core inclined hole 31 is inclined to the mold opening direction. In this embodiment, the angle between the core inclined hole 31 and the mold opening direction is 15°-30°.

[0026] The inclined ejector rod 2 passes through the core inclined hole 31 of the dynamic mold core 3, and one end of the inclined ejector rod 2 away from the processing cavity is guided and connected in the ejector panel 4. A limit track is slidably arranged in the ejector panel 4, and the limit track is connected to the inclined ejector rod 2 through a fixing pin 5. The inclined ejector rod 2 can reciprocate along the limit track; the moving direction of the limit track is perpendicular to the mold opening direction.

[0027] The ejector panel 4 is externally connected to an oil cylinder, an air cylinder or a telescopic rod driving structure to control the ejector panel 4 to move toward or away from the dynamic model core 3 .

[0028] See attached Figure 4 As shown, the inclined ejector rod 2 includes an inclined rod 21 and a ejector head 22. The inclined rod 21 is a straight rod structure arranged obliquely. The ejector head 22 is integrally arranged at one end of the inclined rod 21 close to the processing cavity. The ejector pin assembly 1 is installed in the ejector head 22.

[0029] See attached Figure 4 As shown, the ejector assembly 1 includes an ejector fixing plate 11 and a spring 13. The ejector fixing plate 11 is slidably connected in a groove set in the ejector head 22. A spring 13 abuts between the ejector fixing plate 11 and the bottom of the groove. The spring 13 maintains a preload force to push the ejector fixing plate 11 outward. The end face of the ejector fixing plate 11 is provided with an inclined guide surface 14 that cooperates with the inclined hole 31 of the core. When the ejector head 22 enters the inclined hole 31 of the core, the inclined guide surface 14 abuts against the inner wall of the inclined hole 31 of the core, thereby pressing the ejector fixing plate 11 into the inclined ejector rod 2; when the ejector head 22 leaves the inclined hole 31 of the core, the spring 13 ejects the ejector fixing plate 11 to pop out the inclined ejector rod 2, thereby pushing the processed product to be separated from the inclined ejector rod 2.

[0030] In order to ensure stable extrusion of the spring 13, a through hole perpendicular to the mold opening direction is provided in the ejector head 22, and a bolt 12 is slidably installed in the through hole. One end of the bolt cap of the bolt 12 is fixed in the ejector fixing plate 11 through a hexagonal screw plug, and the stud part of the bolt 12 is coaxially arranged in the through hole.

[0031] Working methods of this structure:

[0032] See attached Figure 1 , 5 As shown, in the mold closing state, the inclined ejector rod 2 cooperates with the inclined hole 31 of the core, and the limiting inclined ejector rod 2 cannot retreat.

[0033] See attached Figure 2As shown, during the opening process, the movable mold core 3 is opened, the ejector panel 4 drives the inclined ejector rod 2 to move upward, the inclined ejector rod 2 slides upward along the inclined hole 31 of the core, and the ejector fixing plate 11 is pressed by the inclined hole 31 of the core and starts to slide.

[0034] See attached Figure 3 , 6 As shown, after being fully ejected, the ejector pin fixing plate 11 in the inclined ejector is pressed by the spring 13 to return to the original position.

[0035] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
