【Embodiment】
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
As shown in Figure 1 to Figure 3, in the present embodiment, a kind of method for protecting product safety depanning, includes the following steps：
A, mold；Oil cylinder 8 drives the line position 4 of mould to retreat, and the mould includes substrate 1 and sets on substrate 1
Rear cavity 2, is provided with wearing plate 3 on substrate 1, be provided with the wearing plate 3 can relative wear plate 3 slide and then and rear cavity
2 line positions 4 for being molded or being demoulded, the opposite line position 4 in the demoulding is provided with the line position 4 and slides and product 5 is consolidated
Fixed delay protection mechanism 6, the delay protection mechanism 6 include the pin pressing plate 61 that can be slided with respect to line position 4, the pin
It is provided through line position 4 and the delay thimble 62 being supported to product 5 on pressing plate 61, during molding, pin pressing plate 61 and line position 4
Between there is gap 10, be additionally provided with the pin pressing plate 61 through line position 4 and guide-localization carried out to 4 glide direction of line position
Guide pin 63, the groove 21 being inserted into for guide pin 63 is offered in the rear cavity 2；
B, when the distance that line position 4 retreats is less than or equal to 4mm, delay thimble 62 and guide pin 63 remain stationary as and withstand production
Product, line position 4 continue to retreat；
C, when the distance that line position 4 retreats is more than 4mm, it is specified that line position 4 drives be delayed thimble 62 and guide pin 63 to back to
Position；
D, product 5 is taken out.
The present invention makes initial rank of the line position during retrogressing by increasing delay protection structure in the line position of mould
Section, the delay thimble in delay protection structure withstands product to help line position glue position to depart from line position, and technique is simple, securely and reliably,
It is of low cost.
As shown in Figure 1 to Figure 3, in the present embodiment, the delay protection mechanism 6, which has further included, is arranged on pin pressing plate
61 sides and the bottom plate 65 fixed with line position 4, are provided with spring 7 between the bottom plate 65 and the pin pressing plate 61, mold
Afterwards, pin pressing plate 61 and bottom plate 65 is spaced a distance, ensures in knockout course, and delay thimble, which withstands product, takes off line position
From line position glue position.
As shown in Figure 1 to Figure 3, in the present embodiment, it is provided with the pin pressing plate 61 for constant time lag thimble 62
With the pin panel 64 of guide pin 63.
As shown in Figure 1 to Figure 3, in the present embodiment, the side of the substrate 1 is provided with the oil cylinder for fixing oil cylinder 8
Seat 9.
As shown in Figure 1, during molding, line position 4 is adjacent to rear cavity 2, the groove 21 of one end insertion rear cavity 2 of guide pin 63
Interior, as shown in Fig. 2, during the demoulding, oil cylinder 8 drives line position 4 to move right, and line position 4 is slided along the direction of guide pin 63, at this time,
Due to setting spring between pin pressing plate 61 and bottom plate 65, the elastic force of spring causes delay thimble 62 to withstand product 5, prevents line position
4 draw bad glue position；As shown in figure 3, completely after the demoulding, guide pin 63 departs from rear cavity 2, and delay thimble 62 also leaves product.
