In some embodiments, the mold further comprises an upper mold fixing plate and a lower mold fixing plate, wherein the upper mold fixing plate is arranged above the fixed mold plate, a hot runner plate is arranged between the upper mold fixing plate and the fixed mold plate, the lower mold fixing plate is arranged below the movable mold plate, and mold legs are arranged between the lower mold fixing plate and the movable mold plate.
In some embodiments, the product ejection device further comprises an ejection mechanism, wherein the ejection mechanism comprises an ejector plate arranged on the lower die fixing plate and an ejector pin arranged on the ejector plate, and the ejector pin is used for ejecting the product.
In some embodiments, the ejector plate comprises an upper ejector plate and a lower ejector plate disposed one above the other.
In some embodiments, the bottom surface of the product is provided with 5 barbs circumferentially opposite.
Compared with the prior art, the utility model has the beneficial effects that:
the injection mold with the back-off structure has the advantages of simple structure, capability of saving the space of the mold, reduction of the production cost of the mold and contribution to smooth demolding of products.

FIG. 2 is a schematic diagram of an injection mold with a back-off structure according to an embodiment of the present utility model;
fig. 3 is a cross-sectional view of an injection mold with a back-off structure according to an embodiment of the present utility model.
Detailed Description
The utility model is described in detail below with reference to the drawings and the specific embodiments.
Example 1
As shown in fig. 1:
the bottom surface of the product 10 is provided with 5 barbs 11 in a circumferential direction.
As shown in fig. 2:
The injection mold with the back-off structure sequentially comprises an upper mold fixing plate 21, a hot runner plate 22, a fixed mold plate 23, a movable mold plate 24, mold legs 25 and a lower mold fixing plate 26 from top to bottom, wherein an ejection mechanism comprises an ejector plate arranged on the lower mold fixing plate and ejector pins arranged on the ejector plate, the ejector pins are used for ejecting products, and the ejector pins comprise an upper ejector pin plate 31 and a lower ejector pin plate 32 which are arranged up and down.
As shown in fig. 3:
The injection mold with the back-off structure comprises a fixed mold and a movable mold, wherein the fixed mold comprises a fixed mold plate 23 and a fixed mold core 41, the movable mold comprises a movable mold plate 24 and a movable mold core 42, the fixed mold core 41 and the movable mold core 42 are matched to form a product cavity for forming a product, a plurality of back hooks 11 are oppositely arranged on the bottom surface of the product 10 in a circumferential direction, a plurality of inclined guide posts 51 are arranged on the fixed mold plate 23, a plurality of slide block seats 52 are arranged on the movable mold plate 24, inclined guide post holes are formed in the slide block seats 52, a slide block core 53 is arranged on the inner side of the slide block seats 52, and the inclined guide posts 51 are arranged in the inclined guide post holes in a sliding mode.
Principle of mold opening and closing operation:
the mould is fixed on an upper mould fixing plate and a lower mould fixing plate on an injection molding machine frame (on one side of a nozzle of the injection molding machine). When the mold is opened, the fixed mold plate is opened to drive the inclined guide pillar, the movable mold slide head core is provided with the inclined guide pillar and drives the slide block seat, the slide block seat moves to the two sides and retreats, the slide block seat moves to the two sides along the inclined guide pillar hole to perform lateral parting, and the injection molding piece is separated from the slide block core.
