Detailed Description
The present invention will be more clearly and completely described below by way of a preferred embodiment in conjunction with the accompanying drawings, which are not intended to limit the scope of the invention as described herein.
Fig. 1-4 show that the utility model discloses a gate structure for preventing cracking and deformation of an integrated injection mold for rubber and iron, which comprises a gate runner 3 arranged on a slide block 1 and a rear mold core 2, wherein the gate runner 3 is communicated with a main runner 4 on the slide block 1 for injection molding and rubber feeding, and one end of the gate runner 3 departing from the main runner 4 is communicated with a rubber inlet 5 of an injection molding product; one end of the sprue runner 3 close to the glue inlet 5 adopts a flat glue inlet head 6 with the upper surface and the lower surface gradually converging towards the glue inlet. The utility model discloses a flat pouring head 6 that advances glued structure in current latent glue, easily breaks away from with the product, and it is little to break away from the tractive that makes the product cause simultaneously, can avoid pulling that produces when breaking away from, situations such as deformation.
The utility model discloses a runner channel 3's cross-section is trapezium structure, and runner channel 3's upper portion opening is greater than the bottom opening, at the ejecting in-process of stub bar that the thimble will be in the runner channel, reduces runner channel 3 and promotes the thimble of being convenient for to the resistance of stub bar.
Simultaneously, because current injection moulding product is when the completion of moulding plastics takes out, it is direct to promote the product through the push pedal and deviate from the back mould benevolence, lie in product all around advance in the runner stub bar still with the product between exist be connected, break away from by force, can cause the product to strain the problem of deformation, for this reason, the utility model discloses sprue 4 and runner 3 mutually perpendicular, after the completion of moulding plastics, slide through slider 1 and carry out the tractive to advancing the injection moulding material of jiao kou 5 position and break away from, before carrying out the ejecting of product and taking out, separate stub bar and product earlier to because the product still is in back mould benevolence this moment, the tractive of an independent department can not produce too much influence to product itself, and the utility model discloses the stub bar that flat head 6 that advances formed is little with the bonding area of product, does benefit to the separation more.
After the stub bar is separated, the stub bar needs to be ejected through an ejector pin, the utility model discloses an ejector pin that is used for ejecting injection molding material in the sprue channel after injection molding is arranged below the sprue channel 3 of the slide block 1, and the slide block 1 is provided with an ejector pin hole 7 for the ejector pin to pass through; when moulding plastics, thimble hole 7 staggers each other with the thimble, staggers the distance that the material removed for 5 positions of glue inlet injection moulding are advanced in slider 1 tractive, and when moulding plastics, even the thimble maloperation also can not be to advancing watering the production influence, only after the stub bar is thrown off with the product under slider 1's drive, the thimble just can correspond with thimble hole 7, ejecting with the stub bar under the drive of thimble board, can avoid the maloperation.
The utility model discloses when using, as shown in fig. 3 and fig. 4, in the stage of moulding plastics, runner flow channel 3 with advance gluey mouth 5 intercommunication, the melten gel loops through sprue 4, runner flow channel 3 and gets into in the mould, the thimble of slider 1 below this moment staggers with thimble hole 7 each other, after accomplishing moulding plastics, the melten gel cooling that is in sprue 4 and runner flow channel 3 solidifies, need take out injection moulding product from the mould, the process of taking out is: the parting surface is opened firstly, the slide block 1 is kept still, the front die of the die is separated from the product, then the slide block 1 retreats, the stub bar at the glue inlet 5 is separated from the product, then the ejector pin on the slide block ejects the stub bar, and the ejector block on the back die pushes the product out.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
