Abstract
The utility model relates to a bumper mould. The bumper mould comprises a movable mould assembly, a fixed mould assembly and an ejection assembly, wherein the movable mould assembly comprises a male mould, a male mould fixing plate and a base plate; the fixed mould assembly comprises a female mould and a female mould fixing plate; the ejection assembly comprises an ejector pin plate; the female mould fixing plate and the female mould are fixedly connected; one surface of the male mould fixing plate is fixedly connected with the male mould, and the other surface of the male mould fixing plate is fixedly connected with the base plate; an accommodating groove matched with the ejector pin plate in shape is formed in the male mould fixing plate; the ejector pin plate is embedded into the accommodating groove and is in sliding connection with the accommodating groove. According to the bumper mould provided by the utility model, the ejector pin plate is directly embedded into the accommodating groove in the male mould fixing plate, and a square iron block in a conventional structure is eliminated, so that a mould base can be more compact, and the total thickness of the mould is reduced; the bumper mould can be used on a smaller injection molding machine with a production volume in tonnage, and the injection molding cost is lowered.
Description
Technical field
The utility model relates to injection molding equipment, relates in particular to a kind of bumper mold.
Background technology
Injection mold is divided into dynamic model and cover half two large divisions, and cover half part is arranged on the fixed base plate of injection machine, and dynamic model part is arranged on the mobile seat board of injection machine.When injection moulding, moving. cover half two large divisions closure. plastic warp nozzle enters mold cavity.When die sinking, moving, cover half two large divisions separates, then ejecting mechanism action, thus release plastic.
Slender type bumper (as bumper lower body) projected area is little, and actual required injection machine tonnage is little, if but adopt traditional moulds structure, owing to being subject to the restriction that its mould is thick, having to be placed on larger injection machine and produce.This mode of production will increase considerably its injection moulding cost.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, and a kind of bumper mold is provided, thick to reduce the mould of mould, thereby reduces injection moulding cost.
For achieving the above object, the utility model is by the following technical solutions:
A kind of bumper mold, comprise dynamic model assembly, cover half assembly and ejection assembly, dynamic model assembly comprises punch, punch retainer and base plate, cover half assembly comprises that die and die determine plate, and ejection assembly comprises ejector retainner plate, and die is determined plate and is fixedly connected with die, punch retainer one side is fixedly connected with punch, another side is fixedly connected with base plate, and punch retainer is provided with the holding tank mating with ejector retainner plate profile, and ejector retainner plate embeds in holding tank and the holding tank that is slidably connected.
Further, ejection assembly also comprises push rod and jacking block, and ejector retainner plate is fixed in push rod one end, and the other end is fixedly connected with jacking block, and push rod runs through punch, and jacking block is located on punch.
Further, ejection assembly also comprises hydraulic cylinder, and hydraulic cylinder is fixed on ejector retainner plate, and the output shaft of hydraulic cylinder is fixedly connected with base plate by a connecting rod.
Further, ejection assembly also comprises oblique top and T-shaped, and oblique top is slidably connected on ejector retainner plate by T-shaped.
Further, oblique top is provided with gathering sill and guide pad.
The utility model beneficial effect is compared with prior art:
(1) the utility model directly embeds ejector retainner plate in the holding tank of punch retainer, has reduced the square iron of traditional structure the inside, and it is compacter that mold base seems, thereby make mould gross thickness attenuate, can be used for less injection machine tonnage and produce, and reduced injection moulding cost.
(2) in the utility model, oblique top can directly be fixed on ejector retainner plate, traditional structure has saved the parts such as oblique top connecting rod relatively, owing to there is no processing and the assembling of the part such as square iron, oblique top connecting rod, traditional moulds structure mold weight saving relatively, the security of mould maintenance, transportation and lifting improves, processing and assembly cost are saved
(3) the utility model has reduced the middle connector such as square iron and oblique top connecting rod, and mould strength relatively can be better, and the connection between template is more stable, and therefore positioning precision all can improve relatively with security.

The specific embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is described further and is illustrated.
The first embodiment concrete structure of the present utility model as shown in Figures 1 to 5.This bumper mold comprises dynamic model assembly, cover half assembly and ejection assembly.Dynamic model assembly comprises punch 23, punch retainer 22 and base plate 21.Cover half assembly comprises that die 12 and die determine plate 11.Ejection assembly comprises ejector retainner plate 31.Die is determined plate 11 and is fixedly connected with die 12, and punch retainer 22 one sides are fixedly connected with punch 23, and another side is fixedly connected with base plate 21.Punch retainer 22 is provided with the holding tank 221 mating with ejector retainner plate 31 profiles, and ejector retainner plate 31 embeds in holding tank 221 and slides in holding tank 221.
Ejection assembly also comprises push rod 32 and jacking block 33.Ejector retainner plate 31 is fixed in push rod 32 one end, and the other end is fixedly connected with jacking block 33.Push rod 32 runs through punch 23, and jacking block 33 is located on punch 23.Ejection assembly also comprises hydraulic cylinder 34, and hydraulic cylinder 34 is fixed on ejector retainner plate 31, and the output shaft of hydraulic cylinder 34 is fixedly connected with base plate 21 by a connecting rod 35.
As shown in Figure 6, in the second example structure of the present utility model, the place different from the first embodiment is: in the second embodiment, ejection assembly comprises oblique top 86 and T-shaped 87, and in the first embodiment, there is no oblique top and T-shaped.Oblique top 86 is slidably connected on ejector retainner plate 81 by T-shaped 87.Oblique top 86 is provided with gathering sill 861 and guide pad 862.
