Field of the Invention The present invention relates to a shutter and a mold having the same, which can have a effect of delaying mold opening when the mold is opened. [Prior Art] When the common mold is pressed (or shot), the spray device (such as the spray head) is usually driven away from the public in order to keep the finished mold body in an unrecoverable and clean state. The mother mold body prevents the material of the nozzle from continuing to drip after the mold is opened; then the male and female mold bodies are opened. In the prior art, a shutter is usually installed on the parting surface of the male and female phantoms to generate a closing force between the male and female phantoms so that the male and female phantoms remain temporarily closed when they are about to be opened, and then the (four) leaves the male and female phantoms. The male and female phantoms are separated by the mold opening force to overcome the closing force, thereby achieving the effect of delaying the mold opening. The first opener usually includes a plastic collar that is screwed to the male mold body and a receiving hole that is formed on the female mold body and matches the plastic collar. When the mold is closed, the receiving hole receives the plastic collar therein. When the male and female molds are to be opened, the friction between the receiving hole and the plastic collar can make the male and female molds hold the coffee, and (4) can play the effect of the extension. However, the plastic collar of the shutter is extremely easy to close due to the male and female phantoms. The knife is worn away and wears off, causing the closing force of the shutter to be provided after the subsequent male and female molds are closed; I cannot provide the ideal delayed opening effect. . It is necessary to provide a financial shutter and a mold using the same. SUMMARY OF THE INVENTION: A shutter and a mold having the same will be described below with reference to specific embodiments. The opening (four)' includes a clamping member and a snap member. The clamping member includes a clamping arm, a second clamping arm, a pivoting unit and an elastic body; the first one and the second clamping arm respectively comprise a pivoting end and a clamping end, the holding # And the pivoting end of the second clamping arm and the elastic body are elastically pressed by the pivoting monofilament of the first clamping arm to form an elastic pressing force on the first holding arm and the second holding end 2 A receiving gap is formed between the first clamping arm and the second clamping member. The latching member includes a latching body, and the latching mouth forms an elastic buckle with the clamping member in the receiving gap. The mold 'includes a first mold body and a second mold body that cooperate with each other, and the shutter includes a holding member and a snap member. The clamping member is described on the first molding body, and includes a first clamping arm, a second clamping =, a knotting unit and an elastic body; the first clamping arm and the second clamping member include a pivoting knot And the first clamping portion; the pivoting end and the elastic body are pivoted by the pivoting unit: _ = the first clamping arm and the second clamping The arm and the pressing force form an elastic abutment on the first clamping arm and the temple. The latching member is disposed on the first clamping body, and when the first and second moldings are combined, the buckle is a body. The receiving gap forms an elastic buckle with the clamping member. + should be extended. Compared with the prior art, the bucking of the shutter pivots the elastic body and the pivoting end of the clamping arm: the mutual elasticity of the unit is (4) into the receiving gap, when the buckle body of the fastening component = = 1323218 When the receiving gap is described, the clamping member and the locking member can form an elastic buckle; the elastic locking manner can make the shutter have durable characteristics. When the shutter is applied to a mold, it provides a sufficient closing force to achieve delayed opening. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2, the shutter 1 according to the embodiment of the present invention includes a clamping member 12 and a fastening member 14 that can be engaged with each other. The missing member 12 includes a base 122, a lost arms 124 and 126, a pivoting unit 127 and an elastic body 128. The base 122 is provided with a positioning hole 1220 and a holding hole 1222. The positioning hole 1220 can be a through hole or a blind hole. Typically, the peripheral wall of the locating hole 1220 is provided with internal threads. The holding hole 1222 may be a through hole. The lost arm 124 includes a pivoting end 1242 and a clamping end 1244. The armature end 1242 is provided with a through hole 12420. The clamping arm 126 includes a pivoting end 1262 and a lost end 1264. The pivoting end 1262 is provided with a through hole 12620. The pivoting unit 127 is embedded in the through holes 12420 and 12620 and is, for example, threadedly coupled into the positioning hole 1220 of the base 122 to pivot the pivot ends 1242 and 1262 together and to clamp the arms 124 and 126. It is held on the base 122. The pivoting unit 127 can be a screw or a rivet or the like. The elastic body 128 is a torsion spring disposed between the pivoting ends 1242 and 1262 and serially disposed on the pivoting unit 127. One end portion 1282 of the elastic body 128 abuts against the clamping arm 126, and the other end portion 1284 abuts against the clamping arms 1323218-124, so that the clamping ends 1244 and 1264 of the clamping arms 124, 126 form an elastic pressing force. A receiving gap 129 is formed between the clamping arms 124 and 126. The elastic body 128 can also be a U-shaped or V-shaped metal elastic piece. When the two ends of the U-shaped or V-shaped metal elastic piece respectively abut against the clamping arms 124 and 126, the elastic clamping force can be pressed by the clamping force. The clamping ends 1244 and 1264 of the arms 124 and 126 are elastically pressed to form a receiving gap 129 between the clamping arms 124 and 126. The shape of the receiving gap 129 may be a spindle shape, a diamond shape, an elliptical shape or the like. In this embodiment, the clamping arms 124, 126 respectively have a V-shaped bend with an angle greater than 90 degrees, so that when the clamping ends 1244 and 1264 of the clamping arms 124, 126 are elastically pressed, A diamond-shaped receiving gap 129 is formed between the clamping arms 124 and 126. The latching member 14 includes a body 142 and a latching body 144 extending from the body 142. The body 142 is provided with a through hole 1420. The latching body 144 can be in the form of a spindle, a diamond or an ellipse having a large intermediate and small ends, and is matched with the receiving gap 129, so that the latching body 144 can be correspondingly extended into a spindle shape, a diamond shape or an elliptical shape. The receiving gap 129 forms an elastic snap with the clamping body 12. Referring to Figures 3 and 4, an embodiment of the present invention further provides a mold 20 including a shutter 10, a male mold body 30 and a female mold body 40. The clamp member 12 of the shutter 10 is held by the male mold body 30 by a screw 32 that is bored in the through hole 1222' of the base 122. The latching member 14 of the shutter 10 is fixed to the female mold body 40 by a screw 42 that is inserted into the through hole 1420 of the body 142. As shown in FIG. 3, the male mold body 30 and the female mold body 40 are oriented in the direction of the arrow. In the process of the die-cutting process, the clamping body 144 of the latching member 14 can be elastically pressed against the clamping force by the clamping force applied between the male die body 30 and the female die body 40. The arms 124 and 126 extend into the receiving gap 129 of the clamping member 12 to form an elastic snap 'to generate a sufficient closing force. As shown in FIG. 4, during the process of opening the mold body 30 and the female mold body 4 in the direction of the arrow shown in the figure, the buckle body 144 is temporarily unable to be separated due to the clamping force of the clamp body on the buckle body 144. The receiving member 12 receives the gap 129, so that the male mold body 30 and the female mold body 40 are kept in a closed state; the spraying device (not shown) is separated first, and then the clamping member 12 is overcome by the mold opening force. The clamping force of the latching body 144 causes the latching body 144 to be disengaged from the receiving gap 129, so that the male mold body 30 and the female mold body 40 can be opened. The shutter 10 and the mold 20 having the same, the clamping member 12 of the clamping member 12 is coupled to the pivoting ends 1242 and 1262 of the clamping arms 124 and 126 by the pivoting unit 127. The clamping arms 124 and 126 are pressed against each other to form a receiving gap 129. When the latching body 144 of the latching member 14 extends into the receiving gap 129, the latching member 12 and the latching member 14 can form an elastic card. Buckle; this type of elastic snap-on makes this type of shutter 1 耐用 durable. When the shutter 10 is to be used on the mold 20, it provides a sufficient closing force to achieve delayed opening. In another embodiment of the present invention, the shutter 10 does not include a base, and the clamping arms 124 and 126 of the clamping member 12 are elastically coupled to each other by the pivoting unit 127 and directly fixed to the male mold body 30. . Therefore, the clamping member 12 can be elastically buckled with the fastening member 14 fixed on the female mold body 40, thereby achieving the purpose of delaying opening and closing. 1323218 - In summary, the present invention has indeed met the requirements of the invention patent, and has been filed according to law. However, the above-mentioned embodiments are merely preferred embodiments of the present invention, and those skilled in the art will be able to incorporate the modifications and variations of the invention in the spirit of the invention.
