Abstract
The utility model discloses a plastic mold technical field, especially a plastic mold's mold insert structure. A plastic mold's mold insert structure, includes first mold insert, second mold insert, first screw, second mold insert from the top down connects gradually and is provided with counter bore, connecting hole, the second mold insert passes through first screw that the connecting hole is embedded to be installed in first mold insert, and the head of first screw is arranged in the connecting hole, still including blockking up structure, stifled plug member, block up structure and counter bore sealing connection, and block up shape, size and the shape of counter bore of structure, big or small phase -match, it is provided with rather than extracting the screw hole that the direction is the same to block up the structure, stifled plug member mountable is in the screw hole. The utility model provides an its subassembly of be liable to change plastic mold's mold insert structure.
Description
Technical field
The utility model relates to plastic moulds technology field, especially a kind of insert structure of mould of plastics.
Background technology
In injection-moulded plastic Making mold, for reducing Mold Making cost, be all be that series products occurs when product design, this just makes one set of die produce the different product of homology class by changing insert structure, therefore the polytropy of insert structure seems extremely important.Some insert structure is interconnected by several different mold insert assembly or is embeddedly combined into.The insert structure that the slightly large mold insert of volume forms is embedded in for the mold insert that volume is slightly little, the connected mode of current employing adopts screw fastening to connect, adopt screw fastening connection that the slightly little mold insert of volume can be made to leave a counterbore, the essential hole stayed is installed, and the method solving counterbore is fill and lead up with copper plug after screw tension, when needing to change other volumes slightly little mold insert, copper plug drilling and tapping is taken out, the waste that this mode replacement operation is inconvenient, cause material, the increase of cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of insert structure being easy to change its assembly mould of plastics.
The utility model solves the insert structure of a kind of mould of plastics that its technical problem adopts, comprise the first mold insert, the second mold insert, the first screw, described second mold insert is connected with counterbore, connecting hole from top to bottom successively, described second mold insert is arranged in the first mold insert by the first screw through connecting hole is embedded, and the head of the first screw is arranged in connecting hole, also comprise blockage structure, type of tamper evidence, described blockage structure and counterbore are tightly connected, and the shape of the shape of blockage structure, size and counterbore, size match; Described blockage structure is provided with extracts the identical screwed hole in direction with it, and described type of tamper evidence can be arranged in screwed hole.
Further, described blockage structure material is iron and steel.
Further, described blockage structure and the counterbore mode coordinated that is tightly connected is interference fit.
Further, the bottom of described blockage structure and the bottom of counterbore fit tightly.
Further, the diameter of described counterbore is greater than the diameter of described connecting hole.
Further, described type of tamper evidence is screw.
The beneficial effects of the utility model are: block by adopting blockage structure at counterbore place, ensure the normal use of insert structure, blockage structure is arranged and extracts the identical screwed hole in direction with it, when insert structure uses, type of tamper evidence is arranged in screwed hole and blocks; On the first mold insert, change another kind of second mold insert at needs, only type of tamper evidence need be extracted, at screwed hole place, special extractor is installed, blockage structure is extracted, then the first screw is taken out, change the second mold insert.Thus make, in replacing second mold insert process, damage to be caused to blockage structure, can reuse, avoid the waste of material, reduce costs; Thus make insert structure assembly be easy to change, simple to operate, improve change efficiency, thus improve produce efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Parts, position and numbering in figure: the first mold insert 1, second mold insert 2, connecting hole 21, counterbore 22, first screw 3, blockage structure 4, screwed hole 41, type of tamper evidence 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the insert structure of the utility model mould of plastics, comprise the first mold insert 1, second mold insert 2, first screw 3, described second mold insert 2 is connected with counterbore 22, connecting hole 21 from top to bottom successively, described second mold insert 2 is arranged in the first mold insert 1 by the first screw 3 through connecting hole 21 is embedded, and the head of the first screw 3 is arranged in connecting hole 21, also comprise blockage structure 4, type of tamper evidence 5, described blockage structure 4 is tightly connected with counterbore 22, and the shape of the shape of blockage structure 4, size and counterbore 22, size match; Described blockage structure 4 is provided with extracts the identical screwed hole in direction 41 with it, and described type of tamper evidence 5 is arranged in screwed hole 41, and type of tamper evidence 5 is screw.By adopting at counterbore 22 place blockage structure 4 to block, ensureing the normal use of insert structure, blockage structure 4 being arranged and extracts the identical screwed hole in direction 41 with it, when insert structure uses, type of tamper evidence 5 being arranged in screwed hole 41 and blocking; On the first mold insert 1, change another kind of second mold insert 2 at needs, only type of tamper evidence 5 need be extracted, at screwed hole 41, special extractor is installed at place, is extracted by blockage structure 4, is then taken out by the first screw 3, changes the second mold insert 2.Thus make, in replacing second mold insert 2 process, damage to be caused to blockage structure 4, can reuse, avoid the waste of material, reduce costs; Thus make insert structure assembly be easy to change, simple to operate, improve change efficiency, thus improve produce efficiency.
Concrete, the insert structure of mould of plastics is generally ferrous materials, so blockage structure 4 can adopt iron and steel material quality, and preferred 45# steel.
Concrete, in order to make blockage structure 4 and counterbore 21 fit tightly, stable connection, blockage structure 4 and counterbore 22 mode coordinated that is tightly connected adopts interference fit.
Concrete, in order to make when injection moulding, from blockage structure 4 flash not out, the bottom of blockage structure 4 and the bottom of counterbore 22 fit tightly the generation preventing flash to raw material.Conveniently in the first mold insert 1 and the second mold insert 2 connection procedure, the screw-in of the first screw 3, is beneficial to operation, the diameter of counterbore 22 can be arranged to the diameter being greater than connecting hole 21.
