Abstract

The invention relates to a three-dimensional inner-mould inlay injection (IML) product heating and punching method. A molding die and a punching die are combined into a heatable combined die. An IML product is formed and punched by one step in a combined die closing process. The combined die comprises an upper die part and a lower die part, wherein the upper die part consists of four guide sleeves, an upper formwork, a punch head fixing plate, a discharging plate and a punch head; a heating rod and a thermoelectric couple are embedded on the side faces of the punch head fixing plate respectively and connected with a control meter through an electric cable respectively; the lower die part consists of a lower formwork, a ball guide sleeve, four guide pillars, two base plates and a concave formwork; and two heating rods and one thermoelectric couple are embedded on the side faces of the punch head fixing plate respectively and connected with the control meter through the electric cable respectively. By the method, the punching qualification rate of the IML product is up to 90 percent; the production time of the product is shortened; and the production efficiency and the quality of the product are improved. The punching method is easy to operate and the product positioning is accurate, so the method meets requirement of large-scale mass production.

Description

Three-dimensional IML product by heating method for die cutting

Technical field

The present invention relates to three-dimensional IML product method for die cutting, particularly a kind of three-dimensional IML product by heating method for die cutting is need to be applied to one time-completion shaping and die-cut IML product.

Background technology

Usually the IML product all be carry out again behind the first moulding gestalt shape die-cut, can increase so many in the middle of turnover and operating time, and reduced production efficiency and product quality; And three-dimensional IML product application of heat method for die cutting can and die-cutly be merged into a step with moulding, has so just shortened the production time of product greatly, has improved product quality, and therefore designing and developing of three-dimensional IML product by heating method for die cutting is necessary.

Summary of the invention

The objective of the invention is the deficiency at the die-cut technology of IML product, promptly the problem that swivel link is many and the operating time is long in the centre provides a kind of new method for die cutting, makes disposable moulding and the Punching Technology finished of IML product energy.

Technical scheme provided by the invention is achieved in that three-dimensional IML product by heating method for die cutting, it is characterized in that, mould and die cutting die are merged into heatable assembling die, the disposable moulding of finishing the IML product and die-cut in assembling die matched moulds process, described assembling die comprises part of the upper die and part of the lower die, the part of the upper die is made of four guide pin bushings, cope match-plate pattern, drift fixed head, stripper and drift, a heating rod and a thermocouple are inlaid in drift fixed head side respectively, and heating rod is connected control instrument with thermocouple difference cable; The part of the lower die is made of lower bolster, four ball bearing guide bushings, four springs, four guide pillars, two backing plates and concave template, and two heating rods and a thermocouple are inlaid in the concave template side respectively, and heating rod and thermocouple cable respectively are connected control instrument; Described method comprises following steps in order;

Step 1, with heating rod mould is heated, the heating setpoint temperature is 85 to 105 degree;

Step 2, etc. arrive design temperature after, sheet material is put on the concave template of assembling die, carry out matched moulds then, carry out sheet forming and die-cut successively;

According to this heating method for die cutting, the die-cut qualification rate of three-dimensional IML product reaches 90%.

The beneficial effect that the present invention carries is that method for die cutting has shortened the production time of product greatly, and has improved the quality of production efficiency and product, and this kind method for die cutting processing ease, product orientation is accurate, and qualification rate can reach more than 90%, is fit to the needs of large-scale production in enormous quantities.

Among the figure: the part name of part of the upper die: guide pin bushing (4), 2. cope match-plate pattern, 3. drift fixed head, 4. stripper, 5. drift, 6. heating rod, 7. thermocouple.

Part of the lower die part name: 8. lower bolster, 9. spring, (4), 10. backing plate (2), 11. concave templates, 12.

Heating rod (2), 13. thermocouples, 14. ball bearing guide bushings (4), 15. guide pillars (4).

The specific embodiment

The inventive method mould therefor structure such as Fig. 1 be to shown in Figure 6, the connected mode of part of the upper die major part: guide pin bushing 1 and cope match-plate pattern 2 are connected by tight fit; Drift fixed head 3 is connected by the M8 screw with cope match-plate pattern 2; Stripper 4 is connected by the discharging screw with drift fixed head 3; Drift 5 passes through with drift fixed head 3

Pin is connected with the M8 screw, and heating rod 6 and drift fixed head 3 are connected by matched in clearance, and thermocouple 7 and drift fixed head 3 are connected by matched in clearance;

The connected mode of part of the lower die major part: lower bolster 8 and guide pillar 15 are connected by tight fit; Ball bearing guide bushing 14 and spring 9 are installed on the guide pillar 15;

Lower bolster 8, backing plate 10, concave template 11 connect by the m8 hexagon socket head cap screw; Heating rod 12 and concave template 11 are connected by matched in clearance; Thermocouple 13 and concave template 11 are connected by matched in clearance;

The method for die cutting of three-dimensional IML product by heating has used the combination that comprises a pair of drift (punch) 5 and concave template (cutting edge) 11 to carry out die-cut; The combination forming of concave template (cutting edge) 11 and stripper 4 goes out the 3D shape of IML product surface in addition.
