Description

Phone cover injection molding

Technical field

The present invention relates to injection-moulding plastic, is phone cover injection molding.

Background technology

In the moulding of phone cover injection, all to adopt loose plug version, it is by after good the processing and manufacturing of inserting, be installed to mould appropriate location by artificial inserting, then matched moulds, after cast, pressurize, cooling curing, mould is opened, the ejecting mechanism that then promotes mould by the push rod of injector goods together with loose plug outside launch mode.Outside mould, by workman, loose plug is separated with goods.This mold mechanism is simple in structure, and die cost is low, is applicable to small lot batch manufacture or trial-production.This mould production efficiency is extremely low, and mould can not automated production, and workman is very dangerous in mould is inserted in installation time, and safety of workers can not get ensureing.Loose plug is manual separation simultaneously, and labor strength is large, and product's dimensional precision can not be guaranteed, and the scrappage of goods is high.In order to overcome the problems referred to above, spy provides following a kind of mold mechanism to solve the problems referred to above.

Summary of the invention

The present invention is to provide phone cover injection molding, and this mould adopts push rod to release design.Few in conjunction with phone cover surface holes, the just more feature of internal holes, this mould adopts maximal projection limit as parting line, adopts mould two chambeies in mold cavity layout, and simultaneously in conjunction with the more feature of goods internal holes, mould adopts ramp-roof structure.According to the border requirement of goods largest contours, die joint is take plane somatotype as main simultaneously, and part adopts ladder somatotype.This mould running gate system is from mold center's line, with nozzle of injector dead in line, and is designed to dismountable sprue bush form, and both sides are fixed on solid plate with screw thread.This die pressure transmission is good, and automaticity is high, products appearance quality grace, the various part convenient processing and manufacture in mold mechanism.Phone cover injection molding, it is characterized in that: top clamping plate (1) is fastenedly connected with soket head cap screw with solid plate (2), cover half die cavity (5) is arranged in the frame of solid plate (2), then be fastenedly connected with soket head cap screw, moving platen (3), mould pin (6), Bottom clamp plate (14) is fastenedly connected with soket head cap screw, centring ring (7) is fastened on top clamping plate (1) with screw (12), sprue bush (8) becomes glade plane space to coordinate with the hole on cover half die cavity (5) with solid plate (2), sprue puller (9) coordinates with moving platen (3) glade plane space, mould top (13) is connected with screw fastening with Bottom clamp plate (14).Phone cover injection molding, has solved the mould of loose plug version, and production efficiency is low, and goods scrappage is high, and labor strength is large, the problem that safety of workers can not be guaranteed.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further described

Fig. 1 is the sectional side elevation of mould matched moulds situation oblique top and die assembly relation

Sectional side elevation when Fig. 2 is the cast of mould matched moulds

Fig. 3 is the top view of mould dynamic model side

Fig. 4 is the top view of stationary mould for mould side

In figure, numeral number represents respectively:

1---top clamping plate 2---solid plate 3---moving platen

4---dynamic model mold insert 5---cover half die cavity 6---mould pin

7---centring ring 8---sprue bush 9---sprue pullers

10---spring 11---water proof ring 12---screws

13---mould top 14---Bottom clamp plate

The specific embodiment:

Shown in figure, be phone cover injection molding, this mold forming material is ABS.The structure of mold cavity and core adopts combined type, and it can reduce heat treatment deformation, is beneficial to exhaust, is convenient to mold repair.Running gate system sprue is positioned on mold center's line, with nozzle of injector dead in line, and is designed to removable sprue bush form, is fixed on solid plate with screw thread, and cast gate adopts side gate charging.The design of mould pushing-off mechanism, little according to the knockout press that goods are required, adopt push rod to release, reach the object of simplifying mold mechanism, its handling ease simultaneously, precision also can reach the requirement of regulation, and its slip resistance is little; Exchange and easy to maintenance, pitched roof mechanism also has the effect of pushing out product simultaneously.Design of Cooling System, due to the temperature of the injection molding filling flow to plastic melt, solidifying and setting, the form and dimensional precision of production efficiency and plastic has important impact.Therefore this mould is many-sided considers that the circulating cooling water channel of rear employing carrys out cooling die.The cooling water channel processing of this form is simple, and good cooling results is installed water proof ring in the moving part of easily leaking easy simultaneously.This mould has adopted mould two cavity structure forms, has selected pitched roof mechanism to complete the interior side core-pulling of endoporus emboss pit, and oblique top plays again the release effect of goods simultaneously.This mode structure compactness, rationally distributed, the module group Rieter of optimization has high automation performance to mould.
