Utility model content
In view of technical problem present in background technique, the technical issues of the utility model is solved be intended to provide it is a kind of not
The plastic nut and its production equipment of vehicle paint can be scratched.
In order to solve the above technical problems, the utility model adopts the following technical solutions:
Plastic nut, including acorn nut ontology, which is characterized in that the nut body has screw hole, the screw hole
The guide surface that inclination extends out is equipped at port, the nut body bottom surface is equipped with plastic layer, and the plastic layer is equipped with same with screw hole
The centre bore of heart setting, the inner wall of the centre bore is vertically arranged with nut bottom and is mutually connected with the guide surface of screw hole, described
Plastic layer edge, which upwardly extends, envelopes nut body edge, and the nut body and plastic layer pass through injection molding connection.
The bottom surface of nut is wrapped by plastic layer, so that one layer of plastic layer is set between nut and vehicle, it will be hard between the two
Property contact be converted into soft contact, be effectively prevented the phenomenon that vehicle paint scratches.
A kind of production equipment of plastic nut, including the cope plate being oppositely arranged up and down and lower template, which is characterized in that institute
The die hole that lower template is used to accommodate nut equipped with front two rows is stated, is equipped between the front row die hole and heel row die hole for connecting
Lead to the longitudinal groove of front row die hole and heel row die hole, the transverse concave groove for being connected to longitudinal groove be additionally provided in the lower template,
The cope plate is equipped in injection hole, the shaped plastics chamber to match with plastic layer shape and screw hole for being inserted into nut
Mold core, the injection hole and transverse concave groove be oppositely arranged up and down, be oppositely arranged above and below the shaped plastics chamber and die hole, it is described on
Template is bonded with lower template so that die hole and shaped plastics chamber form the shape of plastic nut, and the die hole bottom end is equipped with demoulding and pushes away
Head, the production equipment greatly improve the efficiency of plastic nut batch production.
Detailed description of the invention
Fig. 1 is plastic nut structure diagram；
Fig. 2 is plastic nut production equipment structural schematic diagram；
Fig. 3 is lower template structural schematic diagram in the utility model.
Specific embodiment
As shown in Figure 1, plastic nut, including acorn nut ontology 1, the nut body 1 have screw hole 2, screw hole inner wall
Equipped with screw thread, screw hole setting open at one end, the other end is closed, and the guide surface 5 that inclination extends out is equipped at the port of the screw hole 2,
1 bottom surface of nut body is equipped with plastic layer 3, and the plastic layer 3 is equipped with the centre bore 4 being arranged concentrically with screw hole 2, the center
The inner wall in hole 4 is arranged with 1 plane perpendicular of nut and is connected with 5 phase of the guide surface of screw hole 2, and 3 edge of plastic layer upwardly extends
1 edge of nut body is enveloped, the nut body 1 passes through injection molding connection with plastic layer 3.
The bottom surface of nut is wrapped by plastic layer, so that one layer of plastic layer is set between nut and vehicle, it will be hard between the two
Property contact be converted into soft contact, be effectively prevented the phenomenon that vehicle paint scratches；The plastic layer edge is upwardly extended spiral shell
Female edge envelopes, and enables to plastic layer to be closely linked together securely with nut, prevents plastic layer from falling off；Plastics
Layer center bore inner wall is vertically arranged with nut bottom and is mutually connected with the guide surface of screw hole, so that nut can in assembling process
It is more rapidly aligned, plays guiding role.
As shown in Fig. 2, a kind of production equipment of plastic nut, including the cope plate 11 being oppositely arranged up and down and lower template
12, the lower template 12 is equipped with front two rows and is used to accommodate the die hole 13 of nut, in the present embodiment, there are six a row sets,
It is totally ten two two rows of, it is equipped between the front row die hole and heel row die hole recessed for being connected to the longitudinal direction of front-seat die hole and heel row die hole
Slot 14, the transverse concave groove 15 for being connected to longitudinal groove 14 is additionally provided in the lower template 12, and the cope plate 11 is equipped with note
Mold core 18 in the shaped plastics chamber 17 that modeling mouth 16 and plastic layer shape match and the screw hole for being inserted into nut, it is described
The shape of the screw hole of mold core and nut matches setting, and mold core is inserted into blocking screw hole in the screw hole of nut, prevents plastics stream
Enter in die hole, the injection hole 16 is oppositely arranged with about 15 transverse concave groove, and the shaped plastics chamber 17 is opposite with about 13 die hole
Setting, the cope plate 11 is bonded with lower template 12 so that die hole 13 and shaped plastics chamber 17 form the shape of plastic nut, described
13 bottom end of die hole is equipped with demoulding push top 19.
Working principle: nut is placed in the die hole of lower template, and cope plate decline is bonded with lower template, the modeling of cope plate
The die hole that material type chamber is directed at lower template forms injection molding space, and the mold core of cope plate can just block screw hole, then pass through
Injection hole injected plastic makes plastics enter transverse concave groove, then flows into longitudinal groove and eventually flow in injection molding space, plastics at
After type, cope plate, which rises, to be opened, demoulding push top, which is released, releases the plastic nuts that connect together of two rows, will finally be connected together
Plastic nut separates.
The injection hole of the production equipment need to only be arranged one can be molded 12 plastic nuts simultaneously, so that plastic nut batch
The efficiency of amount production improves.
