Abstract
The invention provides an injection molding production process capable of reducing the warping possibility of a plastic plate. The injection molding production process comprises following steps: 1. arranging a smooth platform, adding liquid to the surface of the smooth platform, and uniformly distributing the liquid on the surface of the smooth platform; 2. molding the plastic plate through the injection molding process; 3. arranging the demoulded plastic plate on the smooth platform; 4. applying force so as to enable the plastic plate to abrade the surface of the smooth platform distributed with liquid or enable the plastic plate to vibrate the smooth platform, carrying out vacuum adsorption on the plastic plate and the smooth platform through liquid, and retracting the applied force; 5. further cooling and shaping the plastic plate and the smooth platform subjected to vacuum adsorption; and 6. separating the cooled and shaped plastic plate from the smooth platform, and picking up the plastic plate. According to the injection molding process, the process flow is simple, the use range is wide, the plastic plate only needs to be flatly attached to the smooth platform distributed with liquid; due to the utilization of the vacuum adsorption force, the possibility of warping deformation of the plastic plate in the cooling and shaping process can be reduced, and on the basis of not modifying the original matched production device of injection molding production, the yield of the plastic plate is greatly increased, the injection molding production time is shortened, and the injection molding production process has market economic benefits.
Description
Technical field
The present invention relates to injection moulding technical field of producing, particularly a kind of injection moulding production technology reducing plastic board warpage, is particularly useful for the production requirement of photography luminaire plastic sunscreen plate.
Background technology
Existing plastic board Shooting Technique mainly comprises matched moulds, filling, pressurize, cooling, 5 stages of the demoulding, and wherein the design of cooling system is extremely important.This is because moulded plastic products only has cooling curing to arrive certain rigidity, plastic products after the demoulding, just can be avoided to produce distortion because being subject to external force and internal stress and eliminating process.Owing to accounting for whole molding cycle about 70% ~ 80% cool time, therefore designing good cooling system can significantly shortening forming time, improves injection moulding productivity ratio, reduces costs.Designing cooling system improperly can make molding time elongate, and increases cost; The even buckling deformation that more can cause plastic products further of inhomogeneous cooling.In prior art, conventional die cavity place arranges cooling water pipe, for strengthening cooling effect, increase cooling water pipe number, expand the caliber of cooling water pipe, not only allow injection moulding cost increase, and the more cooling water pipe of number limits by mould structure, can not be uniformly distributed the even buckling deformation causing causing further plastic products of easy inhomogeneous cooling.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of injection moulding production technology reducing plastic board warpage, do not revise original annotation mould produce form a complete production network equipment basis under, greatly increase the yields of plastic board, the injection mo(u)lding production time shortened, have more market economy benefit.
Problem of the present invention is achieved in that a kind of injection moulding production technology reducing plastic board warpage, comprises the steps:
Step 1, a smooth platform is set, to described smooth platform surface adding liquid, makes smooth platform surface be uniformly distributed liquid;
Further, described smooth platform is airtight smooth platform;
Further, described smooth platform is glass or steel plate.
Further, described liquid is water.
Step 2, by plastic board through Shooting Technique manufacture shaping;
Further, described Shooting Technique comprises matched moulds, filling, pressurize, cooling, 5 stages of the demoulding.
Further, described plastic board is photography luminaire plastic sunscreen plate.
Step 3, the plastic board after the described demoulding is positioned over smooth platform;
Step 4, force make plastic board in the smooth platform surface friction of distributes liquid or vibrate smooth platform, by liquid, plastic board and smooth platform vacuum are adsorbed, remove force;
Step 5, the plastic board of vacuum suction and smooth platform are carried out further cooling and shaping.
Further, the described cooling and shaping time is 10min-60min.
Step 6, the plastic board of cooling and shaping is departed from smooth platform, plastic board is picked up.
Further, described plastic board departs from the method for smooth platform and is: go out smooth platform edges edge along smooth platform surface translation.
The invention has the advantages that: injection molding technological process of the present invention is simple, the scope of application is wide, as long as by smooth for plastic board in the smooth platform with liquid; Vacuum adsorption force is utilized to make plastic board reduce buckling deformation in cooling and shaping process, do not revise original annotation mould produce form a complete production network equipment basis under, greatly increase the yields of plastic board, the injection mo(u)lding production time of shortening, have more market economy benefit.
