Abstract

The utility model discloses an exchange mold core type mold comprising a male mold, a female mold, a mold core, a plurality of ejector pins and a mechanism for preventing pulling out before ejection, wherein the mechanism for preventing pulling out before ejection is arranged on the male mold and the female mold and comprises at least one spring-type positioning steel ball, a male mold ejector pin, a female mold ejector pin and a movable positioning pin; the movable positioning pin is provided with a clamping groove; the spring-type positioning steel balls are arranged at two sides of a through hole arranged on the mold core; one end of the male mold ejector pin is contained in a through hole arranged on the male mold, and the other end thereof abuts against a top plate; the female mold ejector pin is embedded on the female mold and corresponds to the position of the through hole of the mold core; and the movable positioning pin is arranged in the through holes in the male mold and the mold core. Through the mechanism for preventing pulling out before ejection, the exchange mold core type mold can prevent an operator from mistaking when the ejector pin ejects a product so as to cause the ejector pin of the mold to be broken, thus reducing the production cost of the product.

Description

Substitute die formula mould

Technical field

The utility model relates to a kind of mould, relate in particular to a kind of prevent maloperation substitute die formula mould.

Background technology

The general thimble that relies on ejects product behind the die swapping type mould molding product, and product and mould are separated, and needs when extracting die out can carry out when thimble withdraws from die fully.

Existing die swapping type mould owing to reasons such as operator maloperations, is extracted die out when thimble ejects product, causes the mould thimble to break, and then increases product costs.

The utility model content

Main purpose of the present utility model is to provide a kind of die formula mould of substituting at the defective that above-mentioned prior art exists, and this mould can prevent that the maloperation of operator when thimble ejects product from causing the mould thimble to break, thereby reduces the producing cost of product.

For achieving the above object, the utility model is substituted die formula mould and is comprised that a male model, a master mold, a die, some thimbles and prevent to eject preceding extraction mechanism.Male model comprises a male model plate, a top board and an accessory plate, and an end offers a caulking groove on the male model plate, and the end in caulking groove on the accessory plate offers a male model through hole, and male model is provided with a cavity, and top board is movable to be installed in the cavity; Die is installed in the caulking groove of male model plate, offers a die through hole that is connected with the male model through hole with male model lead to the hole site corresponding section on the die; Some push pin device are on male model; One master mold and the effect of matching of this male model; Extraction mechanism is installed on male model and the master mold before preventing to eject, comprise at least one spring positioning ball, a male model ejector pin, a master mold ejector pin and a loose pin, loose pin is provided with a support slot, the spring positioning ball is installed on die through hole both sides, male model ejector pin one end is contained in the male model through hole, the other end is resisted against on the top board, and the master mold ejector pin is embedded on the master mold and die lead to the hole site corresponding section, and loose pin is installed in male model through hole and the die through hole.

Described male model through hole upper end is provided with a backstop groove, and described male model bottom offers a perforate that is connected with cavity.

From the above mentioned, the utility model is substituted die formula mould can prevent that by extraction mechanism before preventing to eject the maloperation of operator when thimble ejects product from causing the mould thimble to break, thereby reduces the producing cost of product.

The specific embodiment

For describing technology contents of the present utility model, structural feature and purpose of being reached and effect in detail, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 3, the utility model is substituted die formula mould 100 and is comprised that match with this male model 1 master mold 2, a die 4, the some thimbles (figure does not show) and of effect of a male model 1, prevents to eject preceding extraction mechanism.

See also Fig. 1 and Fig. 2, male model 1 comprises a male model plate 11, a top board 13 and an accessory plate 15, an end offers a caulking groove 111 on the male model plate 11, end in caulking groove 111 on the accessory plate 15 offers a male model through hole 12, male model through hole 12 upper ends are provided with a backstop groove 121, male model 1 is provided with a cavity 14, top board 13 movable being installed in the cavity 14, and male model 1 bottom offers a perforate 16 that is connected with cavity 14.

See also Fig. 1 to Fig. 3, die 4 is installed in the caulking groove 111 of male model plate 11, offers a die through hole 41 that is connected with male model through hole 12 with corresponding section, male model through hole 12 position on the die 4.

See also Fig. 1 to Fig. 3, extraction mechanism is installed on male model 1 and the master mold 2 before preventing to eject, comprise two spring positioning balls 31, a male model ejector pin 32, a master mold ejector pin 33 and a loose pin 34, loose pin 34 is provided with a support slot 341, spring positioning ball 31 is installed on die through hole 41 both sides, male model ejector pin 32 1 ends are contained in the male model through hole 12, the other end is resisted against on the top board 13, master mold ejector pin 33 is embedded on the master mold 2 and corresponding section, die through hole 41 position, and loose pin 34 is installed in male model through hole 12 and the die through hole 41.
