Description
Technical field
The utility model relates to a kind of high-accuracy plastic cement mold.
Background technology
Existing mobile phone parts mostly are plastic cement part, in process of production, often using plastic mould, to carry out integrated punching shaping, but, because mobile phone part is very high to the requirement of precision, so also can correspondingly promote the required precision of plastic mould, in the production of prior art, because the position matching degree between dynamic model and cover half is poor, so the part produced is easy to produce larger error, thus cause part to install, cause waste, improve production cost.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of high-accuracy plastic cement mold.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-accuracy plastic cement mold, comprise cover half and be arranged on the dynamic model above cover half, described dynamic model comprises rectangle briquetting and is arranged on four positioning components on briquetting lower surface, and four positioning components are arranged on four corners of briquetting;
Described positioning component comprises locating piece and locating dowel, the upper end of described locating piece is fixed on briquetting, on the lower surface that described locating dowel is fixed on locating piece and locating dowel stretches into locating piece inside near one end of locating piece, one end that described locating dowel stretches into locating piece inside is provided with limited block, the inside of described locating piece is provided with the cavity mated with the cross section of limited block in cross section, described limited block slides along cavity inner wall, described limited block and cavity form confined space, are provided with hydraulic oil in described cavity.
As preferably, described limited block and locating dowel are formed in one structure.
As preferably, the maximum height of described cavity equals 2 times of limited block thickness.
As preferably, the pressure in described cavity is 1MP.
The beneficial effects of the utility model are, this high-accuracy plastic cement mold is designed by buffer-type location structure, improve the precision of location, improve the qualification rate of product, reduce production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of high-accuracy plastic cement mold of the present utility model;
Fig. 2 is the structural representation of the dynamic model of high-accuracy plastic cement mold of the present utility model;
Fig. 3 is the structural representation of the positioning component of high-accuracy plastic cement mold of the present utility model;
In figure: 1. dynamic model, 2. cover half, 3. locating piece, 4. locating dowel, 5. limited block.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, a kind of high-accuracy plastic cement mold, the dynamic model 1 comprising cover half 2 and be arranged on above cover half 2, described dynamic model 1 comprises rectangle briquetting and is arranged on four positioning components on briquetting lower surface, and four positioning components are arranged on four corners of briquetting;
Described positioning component comprises locating piece 3 and locating dowel 4, the upper end of described locating piece 3 is fixed on briquetting, on the lower surface that described locating dowel 4 is fixed on locating piece 3 and locating dowel 4 stretch into locating piece 3 near one end of locating piece 3 inner, one end that described locating dowel 4 stretches into locating piece 3 inside is provided with limited block 5, the inside of described locating piece 3 is provided with the cavity mated with the cross section of limited block 5 in cross section, described limited block 5 slides along cavity inner wall, described limited block 5 forms confined space with cavity, is provided with hydraulic oil in described cavity.
As preferably, described limited block 5 and locating dowel 4 are formed in one structure.
As preferably, the maximum height of described cavity equals 2 times of limited block 5 thickness.
As preferably, the pressure in described cavity is 1MP.
Adopt buffer-type detent mechanism, utilize the buffer capacity of hydraulic oil, after matched moulds, effectively cushion, dynamic model 1 and cover half 2 can be made to combine tightr, decrease cause because of long-term matched moulds loosening, reduce deviation, improve precision.
Compared with prior art, this high-accuracy plastic cement mold is designed by buffer-type location structure, improves the precision of location, improves the qualification rate of product, reduces production cost.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
