Abstract

The utility model relates to a three-plate die for manufacturing a glass shelf, wherein a first die holder, a second die holder and a third die holder are connected with one another through guide columns and can move along a fixed direction with a fixed displacement; a fourth die holder, a fifth die holder and a seventh die holder are fixedly connected with one another; a sixth die holder is in a guide connection with the fourth die holder; the sixth die holder can move between the fourth die holder and the seventh die holder; a positioning ring is fixed on the face plate of the first die holder; a front die core is fixed on the third die holder; a rear die core is fixed on the fourth die holder; slippers are arranged on three edges of a rear die of the die and positioned by a guide block and a positioning elastic block connected on a fourth die holder plate; an elastic press bar capable of restoring the positioning elastic block is arranged on the guide block; an ejecting rod is connected on an ejecting needle plate; a pneumatic sucker is mounted on the rear die core; and rubber cushion plates are arranged on the die parting surfaces of the front and the rear die cores respectively. The three-plate die solves the problem that the clamping line of the prior die affects the product quality grade.

Description

A kind of three board molds of making multilayer glass shelf

Technical field:

The utility model relates to the machine die technical field, refers in particular to a kind of three board molds of making multilayer glass shelf.

Background technology:

Make the mould of the multilayer glass shelf of using in the article such as refrigerator ice cabinet in the prior art, because structural defective, the difficult shortcoming in composite members location in the ubiquity mould, thereby cause produced multilayer glass shelf product significantly folder mouthful line can occur, influenced the product quality class greatly.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of the solution to press from both sides three board molds that mouthful line influences the manufacturing multilayer glass shelf of product quality class problem in the existing mold.

For achieving the above object, the technical scheme that the utility model provides is: a kind of three board molds of making multilayer glass shelf, include first, two, three, four, five, six, seven standard die sets, preceding die, back die, first mould bases, second mould bases and the 3rd mould bases connect by lead each other, and can directed spacing move, the 4th mould bases, the 5th mould bases and the 7th mould bases are connected to a fixed each other, the 6th mould bases has guiding to be connected with the 4th mould bases, the 6th mould bases can move between the 4th mould bases and the 7th mould bases, centring ring is fixed on the panel of first mould bases, and preceding die is fixed on the 3rd mould bases, and back die is fixed on the 4th mould bases, behind the mould on the mould three limits slide block is set, guide pad and bullet piece location, location by being connected on the 4th mould bases plate are equipped with the bar that suppresses that can make the location play block reset on the guide pad, push rod is connected on the ejector retainner plate, on the back die Pneumatic suction cup is installed, the die die joint is installed the rubber buffer board respectively behind the front mould Renhe.

After adopting technique scheme, owing to slide block in the structure does not contact with the product that makes, so product does not significantly press from both sides a mouthful line, very ingenious the solution pressed from both sides the problem that mouthful line influences the product quality class in this type of mould.

Description of drawings:

Fig. 1 is the structural representation under the utility model matched moulds state.

Fig. 2 is the structural representation under the utility model die opening state.

Fig. 3 is the utility model structure vertical view.

The specific embodiment:

See Fig. 1-shown in Figure 3, present embodiment includes first, two, three, four, five, six, seven

standard die sets

1,2,3,4,5,6,7, preceding die 8, back die 9, first mould bases 1, second mould bases 2 and the 3rd mould bases 3 connect by lead each other, and can directed spacing move, the 4th mould bases 4, the 5th mould bases 5 and the 7th mould bases 7 are connected to a fixed each other, the 6th mould bases 6 has guiding to be connected with the 4th mould bases 4, guarantee the precision of mould bases alignment, the 6th mould bases 6 can move between the 4th mould bases 4 and the 7th mould bases 7, centring ring 20 is fixed on the panel of first mould bases 1, preceding die 8 is fixed on the 3rd mould bases 3, back die 9 is fixed on the 4th mould bases 4, behind the mould on the mould three limits slide block 11 is set, by the guide pad 15 and location bullet piece 14 location that are connected on the 4th mould bases plate 4, be equipped with on the guide pad 15 can make that location bullet piece 14 resets suppress bar 13, push rod 12 is connected on the ejector retainner plate, on the back die 9 Pneumatic suction cup 16 is installed, preceding die 8 and back die 9 die joints are installed the rubber buffer board respectively.

When injection moulding, 7 base plates of the panel of first mould bases 1 and the 7th mould bases are connected on the locked mode plate of injection machine.Mould is opened, and slide block 11 location are used for composite members in the positioning module, and Pneumatic suction cup 16 is fixed composite members in the mould simultaneously.Mould closes and closes, and preceding die 8 will be located bullet piece 14.Suppress bar 13 press reset after, slide block 11 is drawn back resets again, location bullet piece 14 is located once more; The rubber buffer board 17 of die 8 and back die 9 is steady with composite members folder in the mould before being installed on, and injects in the die cavity by feed nozzle through the plastic cement of high-temperature fusion, is shaped to product; After the formed product, the push rod 12 that is connected on the ejector retainner plate ejects product, can take out product; Push rod 12 resets to slide block 11 state of composite members in the positioning module simultaneously.Because slide block 11 does not contact with product in the whole process, so product is not by obvious folder mouthful line.

The embodiment of the above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so all equivalences of doing according to shape of the present utility model, structure and principle change, and all should be covered by within the protection domain of the present utility model.
