Abstract
The utility model relates to an injection mold with an internally flanged safety cover, which comprises a fixed mold cavity, a movable mold cavity, a mold core and a movable mold insert, wherein the fixed mold cavity and the movable mold cavity are matched with each other, and the mold core is inserted into the fixed mold cavity and the movable mold cavity; the fixed mold cavity, the movable mold cavity and the mold core form a mold cavity for an injection molding part; the movable mold insert is fixed in the movable mold cavity, and sheathed on the mold core; the mold core is composed of a molding head and a core bar; the molding head is matched with the fixed mold cavity and the movable mold cavity to form a mold cavity; the core bar is inserted into the movable mold insert; and the bottom of the molding head is matched with the top of the movable mold insert to form an internally flanged part mold cavity for the injection molding part. The injection mold provided by the utility model simplifies the structure of the mold, is easy to manufacture and convenient to maintain, and effectively lowers the manufacturing and maintenance cost of the mold.
Description
Technical field
The utility model relates to a kind of mould, and especially a kind of injection mold of processing the in-flanges protecting cap belongs to the injection mold technical field.
Background technology
Along with popularizing of plastic products, in order to enhance productivity, satisfy growing production and living needs, the technical staff in the industry is when design and manufacturing injection mold, also constantly towards high efficiency, high-quality, the low-cost improvement.For the plastic products of some structure more complicated, the bottle cap on the oil bottle for example.The inboard of this bottle cap, the bottom that is positioned at bottle cap is provided with the in-flanges that extends internally, and promptly the cross section is hook-shaped convexity, and when bottle cap was tightened on the oil bottle, this in-flanges had just played good sealing safety effect.For the injection mould of this bottle cap, generally be the die cavity that constitutes moulding through cover half benevolence, mavable module core and core, and for the in-flanges part, then be with the fixing slide block of spring, through slide block and die formation in-flanges die cavity partly at the chuck place of core.Adopt the injection mold of this structure, the processing more complicated of its core, die and slide block, and also the in-flanges on the bottle cap is arranged in the bottle cap inboard by a plurality of bulge clearances; The manufacturer that has is in order to guarantee product quality; Improve precision, all slider designs is become a plurality of, combine.The structure of this mould is very complicated, and processing is got up also relatively more difficult, and cost is also than higher; In addition,, use a period of time because slide block is to adopt spring controlledly, relaxing of spring just need to change, maintenance is trouble very, has also shortened the time between overhauls(TBO) of mould, has increased technical staff's labour intensity, has increased a large amount of maintenance costs.
The utility model content
The utility model purpose is that a kind of simple in structure, convenient manufacturing is provided for the deficiency that overcomes prior art, effectively reduces the injection mold of the in-flanges protecting cap of manufacturing and maintenance cost.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of injection mold of in-flanges protecting cap comprises cover half benevolence, mavable module core, core and dynamic model mold insert; Said cover half Renhe mavable module core cooperatively interacts, and core inserts in cover half benevolence, the mavable module core; Said cover half benevolence, mavable module core, core form the die cavity of moulding; Said dynamic model mold insert is fixed in the mavable module core, and the dynamic model mold insert is enclosed within on the core; Said core is made up of moulded head and core bar; Said moulded head cooperates with cover half benevolence, mavable module core, forms die cavity; Said core bar inserts in the dynamic model mold insert; The top of the bottom of said moulded head and dynamic model mold insert cooperates, and forms the in-flanges part die cavity of moulding.
Preferably, the outside of said dynamic model mold insert, the face that matches with mavable module core is the conical surface.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The injection mold of a kind of in-flanges protecting cap of the utility model scheme utilizes the dynamic model mold insert to replace slide block, has cancelled the spring on the core chuck; Simplified mould structure; And easy to manufacture, easy to maintenance, effectively reduce the manufacturing and the maintenance cost of mould; Also increase the time between overhauls(TBO) of mould, reduced labor intensity of operating personnel.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of injection mold of the in-flanges protecting cap of the utility model;
Wherein: 1, cover half benevolence; 2, mavable module core; 3, die cavity; 4, core; 5, moulded head; 6, core bar; 7, dynamic model mold insert.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1 is the injection mold of the described a kind of in-flanges protecting cap of the utility model, comprises cover half benevolence 1, mavable module core 2, core 4 and dynamic model mold insert 7; Said cover half benevolence 1 cooperatively interacts with mavable module core 2, and core 4 inserts in cover half benevolence 1, the mavable module core 2; Said cover half benevolence 1, mavable module core 2, core 4 form the die cavity 3 of mouldings; Said dynamic model mold insert 7 is fixed in the mavable module core 2, and dynamic model mold insert 7 is enclosed within on the core 4; Said core 4 is made up of moulded head 5 and core bar 6; Said moulded head 5 cooperates with cover half benevolence 1, mavable module core 2, forms die cavity 3; Said core bar 6 inserts in the dynamic model mold insert 7; The top of the bottom of said moulded head 5 and dynamic model mold insert 7 cooperates, and forms the in-flanges part die cavity of moulding; The outside of said dynamic model mold insert 7, the face that matches with mavable module core 2 is the conical surface.Owing to adopt the moulded head on dynamic model mold insert and the core, with the die cavity of mavable module core, cover half benevolence formation moulding, this injection mold simple in structure; And it is easy to manufacture; Cancel spring and slide block structure, repaired very conveniently, effectively reduced the manufacturing and the maintenance cost of mould.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
