Referring to fig. 1 to 3:

according to an aspect of the utility model, the utility model provides a mold, including front mould and back mould, the back mould has first portion 1 and second portion 2, offers the through-hole 21 that the terminal surface that supplies a tip of first portion 1 to pass on the second portion 2, and the side direction translation activity of perpendicular to fore-and-aft direction can be done for second portion 2 in first portion 1, still includes: ejecting structure, it includes: a top plate 3 and two thimbles 4; the top plate 3 is positioned above the first part 1 in the rear mould and spans the first part 1 of the rear mould, and two ends of the top plate 3 respectively protrude out of two ends of the first part 1 of the rear mould; two ejector pins 4 connected to two ends of the top plate 3, the two ejector pins 4 being located at two sides of the first portion 1 of the rear mold; the top plate 3 is provided with a first molding cavity section 31, the second part 2 of the rear mold is provided with a second molding cavity section 22, the end face of one end part of the first part 1 is provided with a third molding cavity section 11, and the first molding cavity section 31, the second molding cavity section 22 and the third molding cavity section 11 form a molding cavity part.

With the arrangement, when the mold is demolded, because the first molding cavity section 31, the second molding cavity section 22 and the third molding cavity section 11 form a molding cavity part, when a product in the molding cavity part needs to be ejected, the first part 1 and the second part 2 of the rear mold are separated, the first molding section on the top plate 3 is above the first part 1 of the rear mold, and the top plate 3 can be ejected through the ejector pins 4 at two ends of the top plate 3, so that the product is ejected; through the mode of roof 3 bridging (being that roof 3 is located the first portion 1 top in the back mould and spanes the first portion 1 of back mould), can be nimble convenient ejecting with the product, solved thimble 4 and can not pass the problem of first portion 1.

Specifically, in an embodiment of the present application, a groove 23 matching with the top plate 3 is formed on the second portion 2 of the rear mold, a first hole 231 and a second hole 232 through which the two ejector pins 4 pass are formed at two ends in the groove 23, and the two ejector pins 4 respectively pass through the first hole 231 and the second hole 232 to be connected with two ends of the top plate 3; due to the arrangement, the top plate 3 is arranged in the groove 23, the design is convenient, the space is saved, and in addition, the first hole 231 and the second hole 232 can play a limiting role in the ejector pin 4, so that the ejector pin 4 cannot deviate.

In some embodiments, two thimbles 4 are connected with two ends of the top plate 3 through bolts; such an arrangement allows the thimble 4 to be easily maintained and assembled, for example, when one of the thimbles 4 is damaged, the damaged thimble 4 may be removed and replaced. Similarly, if the top plate 3 is damaged, the top plate is also disassembled and replaced similarly.

In order to realize that the ejector pins 4 can eject products more stably without deviation, specifically, in some embodiments, the two ejector pins 4 are sleeved with the limiting sleeves 5; due to the arrangement, the ejector pin 4 can stably eject products at a limited position more stably under the action of the limiting sleeve 5, and deviation cannot occur.

In order to realize that the first portion 1 can stably do the lateral translation activity perpendicular to the front-back direction relative to the second portion 2, specifically, in some embodiments, both sides of the first portion 1 are provided with the sliding edges 12, the two sliding edges 12 are provided with the limiting blocks 6, and the first portion 1 moves under the limiting effect of the two limiting blocks 6 through the two sliding edges 12 without deviation.

In one embodiment of the present application, in order to enable the other end of the first portion 1 to push one end of the first portion 1, a lateral translational motion perpendicular to the front-back direction is performed with respect to the second portion 2, specifically, the other end of the first portion 1 is a pushing device 7, and the one end and the other end of the first portion 1 are connected by a pushing member 8.

Specifically, in one embodiment of the present application, the pushing device 7 is a hydraulic cylinder, the pushing member 8 is a pushing rod, and a pushing end of the hydraulic cylinder is connected with one end of the first portion 1 through the pushing rod; during operation, the hydraulic cylinder is actuated (i.e. the above-mentioned pushing means 7, i.e. the other end of the first portion 1) to push one end of the first portion 1 by means of a pushing rod (i.e. the above-mentioned pushing member 8); it should be noted that the above-mentioned action can push one end of the first portion 1 to extend (i.e. to translate laterally perpendicular to the front-back direction), when the mold is to be removed, the hydraulic rod is started, and the third molding cavity section 11 on the end face of one end of the first portion 1 moves in the direction away from the through hole 21 formed on the second portion 2, so that the cooled product is separated from the end face of one end of the first portion 1; when the third molding cavity segment 11 needs to form a molding cavity with the first molding cavity segment 31 and the second molding cavity segment 22, only the hydraulic rod needs to be started, so that the third molding cavity segment 11 on the end surface of one end of the first portion 1 moves, and the third molding cavity segment passes through the through hole 21 on the second portion 2, and the end surface of one end of the first portion 1 passes through the through hole.

Based on the technical scheme, the embodiment of the utility model provides an at least, following advantage and positive effect have:

the utility model discloses the mould of embodiment, when the mould drawing of patterns, because first molding cavity section 31, second molding cavity section 22 and third molding cavity section 11 shape molding cavity portion, when the product of molding cavity portion needs ejecting, first portion 1 and the separation of second portion 2 of back mould, first molding section on roof 3 is in the first portion 1 top of back mould, can be through the thimble 4 at roof 3 both ends with roof 3 ejecting roof 3 to push out the product wholly, the product drawing of patterns qualification rate is high; through the mode of roof 3 bridging (namely roof 3 is located the first portion 1 top in the back mould and spanes the first portion 1 of back mould), can be nimble convenient ejecting with the product, solved thimble 4 and can not pass the problem of the first portion 1 that the back mould of mould has.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terms used are words of description and illustration, rather than words of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
