Embodiment
Refering to shown in Fig. 1-4, a kind of mould back-off mould unloading structure, including from top to bottom set gradually die cavity 1, rear cavity
2nd, B plates 3, mold base square iron 4, thimble panel 5, Ejector Retainer Plate 6 and mold base bottom plate 7, the mold base square iron 4 are located at the He of thimble panel 5
The both sides of Ejector Retainer Plate 6, stroke gap 51 is provided between the thimble panel 5 and B plates 3；The Ejector Retainer Plate 6 is provided with thimble 61
Die cavity 1 is connected to, the mold base bottom plate 7 is communicated to die cavity 1, the T-shaped back-off jacking block 62 and B provided with T-shaped back-off jacking block 62
Ejection stroke 52 is provided between plate 3, the upper end of T-shaped back-off jacking block 62 is provided with back-off mould 67, and lower end is provided with top cap 68 and bullet
Spring 64.
The spring 64 is provided with pressing plate 63 and spring leads the tip 65, and the spring leads the tip 65 and T-shaped back-off jacking block 62 and pressure
Plate 63 connects, and spring 64 is placed on spring and led on the tip 65.
Rear mold mold insert 66 is provided between the T-shaped back-off jacking block 62, facilitates the processing, installation and maintenance of T-shaped back-off jacking block,
Deformation space is made for back-off ejection.
The Ejector Retainer Plate 6 is provided with top cap groove 69.
To further appreciate that the operation principle of the utility model, the structure is described further below：
After the completion of injection, because the lower end of T-shaped back-off jacking block 62 is provided with spring 64, spring 64 is in compression shape before ejection
State, thimble panel 5 drives thimble 61, and ejecting product 8, the first time of thimble 61 eject product 8 upwards forward, i.e. the depanning of product 8
(such as Fig. 3), while the elastic force of spring 64 pushes ahead T-shaped back-off jacking block 62 so that it travels forward together with product 8, by
In the "T"-shaped setting that back-off jacking block 62 is middle part, after having moved ejection stroke 52, B plates 3 play position-limiting action, complete for the first time
Ejection, deformation space is vacateed for the depanning of the back-off position of product 8；Then thimble panel 5 continues through the ejecting product forward of thimble 61
8, T-shaped back-off jacking block 62 is stopped by B plates 3, can not promote further along, so as to which back-off position deforms so that product 8 falls in T-shaped
Detain and ejection is forced on jacking block 62, detach T-shaped back-off jacking block 62, complete back-off depanning (such as Fig. 4)；After depanning, whole mould is answered
Position, T-shaped back-off jacking block 62 are together resetted by the top cap 68 being arranged in the top cap groove 69 of Ejector Retainer Plate 6 with Ejector Retainer Plate 6, bullet
Spring 64 recovers compressive state, and back-off mould 67 resets to die cavity 1, treats to be molded next time.
The beneficial effects of the utility model are：By setting T-shaped back-off jacking block and spring, ejecting product at twice, first
