Abstract
The invention provides a process method for punching the inside of an automobile inner decorative mould. The inside of a compression moulding mould is provided with a cavity punching device for an automobile inner decorative, and the outer edge of the compression moulding mould is provided with a floating type shear trimming device. The moulding production process flows comprise the following steps: (1) heating base materials of automobile inner decorative products to soften the base materials; (2) compounding non-woven fabrics on the softened base materials; and (3) arranging the compression moulding mould on a press, placing the base materials compounded with the non-woven fabrics on a working plane of the compression moulding mould, starting the mould to complete forming, punching, cavity punching and trimming of the automobile inner decorative for one time, completing mould pressing of the automobile inner decorative, and directly entering the assembly working procedure. The process method combines the prior compression moulding, cavity punching and trimming into a set of mould, and realizes completion of the compression moulding, the cavity punching and the trimming for one time to save working procedures, reduce equipment investment and production cost of products, and improve production efficiency.
Description
Technical field
The present invention relates to process method for punching inside of automobile inner decorative mould.
Background technology
Automotive upholstery is generally thermoplastic, is distributed with a plurality of vestibules on it.After traditional automotive upholstery all adopts the monnolithic case compression molding, the operation of secondary punching, die-cut vestibule and deburring again.The operation of secondary punching chamber and deburring mainly contains following three kinds of modes and carries out: 1. water under high pressure is cut; 2. die-cut stamping is cut; 3. manual punching chamber, deburring.These three kinds of methods, or product precision height, the production efficiency height, but drop into bigger; Drop into lowlyer, but production efficiency is low, and product quality is also relatively low.Solve so during inside gadget produces, reducing the mould input, shorten the construction cycle, making full use of under the prerequisite of resource of existing equipment, high efficiencyly produce superior in quality product, become a breach of inside gadget process exploitation.
Summary of the invention
The purpose of this invention is to provide a kind of process method for punching inside of automobile inner decorative mould,, reduce production cost of products, enhance productivity to save operation.
For this reason, technical scheme of the present invention is: process method for punching inside of automobile inner decorative mould, comprise the compression molding mould, it is characterized in that: increase the die-cut vestibule device that automotive upholstery is arranged in the compression molding mould, increasing in compression molding mould outer simultaneously has floating type shear knife edge-neatening apparatus; Concrete molding production process flow process is: (1). heating automotive upholstery product base material makes it softening; (2). compound nonwoven cloth on the base material after softening; (3). the compression molding mould is installed on the forcing press, then the base material behind the compound nonwoven cloth is placed on the working face of compression molding mould, start and touch tool, once finish moulding, punching, die-cut cavity and the deburring of automotive upholstery, the automotive upholstery mold pressing is finished, and directly enters assembly process then.
Beneficial effect: the present invention is combined in a cover to existing compression molding, die-cut vestibule and deburring and touches in the tool, realization compression molding, punching chamber and deburring are once finished, thereby have saved operation, have reduced the equipment input, reduce production cost of products, enhance productivity.
Description of drawings
Fig. 1 is the basic structure schematic diagram of compression molding mould of the present invention.
Fig. 2 is shearing mechanism figure.
Fig. 3 is a flow sheet of the present invention.
The specific embodiment
Die-cut definition in the mould: die-cut technology is by increasing floating type shear knife in mould, having realized a kind of novel technique that formed product and punching deburring are finished synchronously in the inside gadget mould.Mainly be to carry out in the production process of mold pressing, finish simultaneously that generally the moulding material that uses is thermoplastic, as PP fiber crops felt plate, PP wood flour board etc. to the deburring of product and the die-cut work in moulding hole at goods.
As follows in conjunction with describing the present invention shown in Fig. 1,2,3:
As shown in Figure 1, the compression molding mould comprises cope match-plate pattern 1, lower bolster 5, be installed in patrix 7 on the cope match-plate pattern 1, be installed in the counterdie 6 on the lower bolster 5, in the patrix 7 of compression molding mould, counterdie 6, increase die-cut vestibule device is arranged, be provided with floating type shear knife edge-neatening apparatus in compression molding mould outer, form by the last shearing edge of a knife 2, the down cut edge of a knife 4.As shown in Figure 2, be to go up the shearing signal of shearing between the edge of a knife 2, the down cut edge of a knife 4, identical with the shearing mechanism of plate shearing machine.
As shown in Figure 3, describing process is: (1). heating automotive upholstery product base material, and heating-up temperature is 190～230 ℃, be 40～60s heat time heating time; (2). compound nonwoven cloth on the base material after softening; (3). the compression molding mould is installed on the forcing press, then the base material behind the compound nonwoven cloth is placed on the working face of compression molding mould, start and touch tool, once finish moulding, punching, die-cut cavity and the deburring of automotive upholstery, wherein molding pressure is 0.3～0.4Mpa, and clamp time is 30～50s; (4), the automotive upholstery mold pressing finishes, and directly enters assembly process then.
Cover decoration piece behind the luggage case for example, the material that uses is the CPP wood flour board of thickness as 1mm, compound 100g/cm on it
2Nonwoven.Formed product mode: Far-infrared Heating → compression molding (die-cut in deburring, the mould).
Process method for punching and traditional other three kinds of processes (water under high pressure is cut, and blanking die is die-cut, manual punching, deburring) strengths and weaknesses analysis are as follows in the mould:
1, process method for punching in the mould: product size precision, production efficiency are all very high, and development cost is lower.
2, water under high pressure cutting process method: the product size precision is higher, can realize Flexible Production, and production efficiency is low, have high input, Operating environment is poor.
3, stamping cutting process method is cut in the hole: product size precision height, mould has high input, the development cost height.
4, manual punching, deburring process: the product size precision is relatively poor, and production efficiency is low, and mould structure is simple, development cost is low.
