Problems solved by technology
However, when the space between the two ribs is too small and there is not enough space, the oblique pin cannot be used in the mold design. When the ordinary ejector pin is used for ejection, the ribs are not easy to be ejected due to the small barbs on the ribs. take out
[0003] In view of this, it is necessary to design a jacking block ejection mechanism to solve the problem that the rib cannot be ejected quickly when there are small barbs on the front rib

Embodiment Construction
[0023] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Please refer to Figure 1 to Figure 2 , figure 1 It is a schematic sectional view of the ejector mechanism of the present invention before ejection and figure 2 It is a schematic cross-sectional view of the movable jack block of the jack block ejection mechanism of the present invention before ejection. The jack block ejector mechanism 100 of the present invention is applied in a mold to eject the product 300. The product 300 is provided with a plurality of ribs 301. The height of the ribs 301 is S1, and the ribs 301 have barbs 302. The mold includes an upper fixed plate 101, a hot runner plate 102, a female template 103, a female mold core 104, a male mold core 105, a male template 106, an upper ejector plate 107, a lower ejector plate 108, a lower fixed plate 109 and several ejector pins. 110, it is characterized in t...

The invention provides an ejector block ejection mechanism. The ejector block ejection mechanism comprises a movable ejector block, a first ejector rod, a pin, an ejector block and a second ejector rod; the movable ejector block is vertically and movably arranged in a male mold core, and the upper end of the movable ejector block is matched with a rib used for molding a product; the first ejector rod is arranged under the movable ejector block, the lower end of the first ejector rod is fixed to a countersunk head and arranged in an upper ejector plate, and the upper end of the first ejector rod is movably arranged in the male mold core and a male mold plate in a penetrating manner; the lower end of the pin is arranged on a lower fixing plate, the upper end of the pin is arranged in a lower ejector plate, and the pin is connected with the first ejector rod through an elastic element; the ejector block is vertically and movably arranged in the male mold core and the male mold plate, and the upper end of the ejector block stretches into the product; the second ejector rod is arranged under the ejector block, the lower end of the second ejector rod is fixedly arranged on the upper ejector plate, and the upper end of the second ejector rod is movably arranged in the male mold core and the male mold plate in a penetrating manner. According to the ejector block ejection mechanism, forced demolding is achieved in a two-time ejection manner. The ejector block ejection mechanism is simple in structure and convenient to machine and facilitates mold assembling and disassembling.
Description
【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a jack block ejection mechanism capable of ejecting products and forcibly demolding them. 【Background technique】 [0002] At present, in order to better place the internal connecting wires in the cover of some electronic products, a row of ribs are generally designed on the cover, and one end of the rib is provided with a small barb, which can effectively connect the connecting wires Snap into this rib to keep the connecting wires fixed and arranged in an orderly manner. However, when the space between the two ribs is too small and there is not enough space, the oblique pin cannot be used in the mold design. When the ordinary ejector pin is used for ejection, the ribs are not easy to be ejected due to the small barbs on the ribs. take out. [0003] In view of this, it is necessary to design a jacking block ejection mechanism to solve the problem that the front rib cannot be ejected quickly...
