The sequential demoulding mechanism comprises an upper doubling plate and a lower doubling plate, wherein a sprue plate is connected to the lower part of the upper double plate; a sprue bush is mounted in the sprue plate which is connected to a cavity; a mould leg is mounted on the lower doubling plate; an upper top plate and a lower top plate are arranged in the mould leg; top rods are connected to the upper and lower top plates; a core plate is mounted on the mould leg; a core is arranged on the core plate; a mould cavity is formed between the core and the cavity; a formed product is in the mould cavity; a material handle is reserved between the product and the sprue plate; a material pushing plate is arranged on the core plate; the top surface of the material pushing plate is contacted with the product; the top rods pass through the core plate to connect the material pushing plate; the sequential demoulding mechanism is characterized in that a spring slot is provided with a spring slot; a compression spring is mounted in the spring slot; the compression spring is contacted with the sprue plate; a fixed-distance pull rod is connected to lower part of the sprue plate; the fixed-distance pull rod passes through the compression spring and the spring slot. The demoulding mechanism of the scheme is simple in structure, easy to machine, convenient to installation and low in cost.
Description
Technical field
The utility model relates to a kind of injection mold spring order stripping mechanism, belongs to the injection mold field.
Background technology
At present, when producing the plastic product of similar containers, the structure of the traditional injection moulding mould normally core of mould stretches into the product inwall; The die cavity of mould is coated on the product outer wall, and the gap between core and the die cavity constitutes the die cavity of product, and mould structure is simple; Handling ease, therefore, people process the die cavity and the core of many (more than two) in a width of cloth mould; Make many products of an injection moulding of mould, enhance productivity.But, in actual production, because the plastic product that adopts injection mold to produce; One (surplus) material handle must be arranged on every product, and the material handle is stayed in runner and the cast gate, is connected with product; Therefore; Before product stripping, must solve the material handle earlier and separate the problem that product could be deviate from smoothly with product.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, a kind of effect that utilizes compression spring and controlled interval pull rod to be provided, make the mould twice-die-opening, product smooth and material handle and die cavity disengaging, the injection mold spring order stripping mechanism that is convenient in demoulding.
The technical scheme of the utility model injection mold spring order stripping mechanism is: comprise compound plate and following compound plate on the mould, last compound plate connects gate plate down, and sprue bush is installed in the gate plate, and gate plate connects die cavity; The mould pin is installed on the following compound plate, upper plate and lower roof plate are set in the mould pin, connect push rod on the upper and lower top board, mount type central layer on the mould pin; Be shaped on core on the core plate, constitute die cavity between core and the die cavity, the product of moulding is arranged in the die cavity; Leave the material handle between product and the gate plate, on the described core plate scraping wings is set, the end face of scraping wings contacts with product; Push rod passes core plate and connects scraping wings, it is characterized in that having spring groove in the described die cavity, and the compression spring is installed in the spring groove; The compression spring contacts with gate plate, and gate plate connects controlled interval pull rod down, and controlled interval pull rod passes compression spring and spring groove.
The injection mold spring order stripping mechanism of the utility model, during the demoulding, injection machine power drives core and die cavity breaks away from die sinking; But because the compression spring is installed in the spring groove of die cavity, the compression spring contacts with gate plate; After the mould die sinking, the compression spring has not had clamp force, withstands under the gate plate; Die cavity is separated with gate plate, and die cavity moves to the return stroke of compressing spring downwards with core, and product and material handle are broken; This moment, product was still stayed in the die cavity, and the material handle is stayed in the gate plate, will expect that by manual work or manipulator handle takes out.After compression spring bullet was intact, core continued operation die sinking downwards, separated with die cavity, and this moment, product was stayed on the core, and by scraping wings product was released outside the mould, and the demoulding is accomplished.This programme adopts the reseting elasticity of compression spring, makes the mould twice-die-opening, and product and material handle are broken, and makes product stay on the core to deviate from smoothly, and is simple in structure, handling ease, and easy for installation, cost is economized.

The specific embodiment
The utility model relates to a kind of injection mold spring order stripping mechanism, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould, 1 time connection of last compound plate gate plate 3; Sprue bush 4 is installed in the gate plate, and gate plate 3 connects die cavity 5, and mould pin 6 is installed on the following compound plate 2; Upper plate 7 and lower roof plate 8 are set in the mould pin, connect push rod 9, mount type central layer 10 on mould pin 6 on the upper and lower top board; Be shaped on core 11 on the core plate 10, constitute die cavity between core 11 and the die cavity 5, the product 12 of moulding is arranged in the die cavity; Leave material handle 13 between product 12 and the gate plate 3, on the described core plate 10 scraping wings 14 is set, the end face of scraping wings 14 contacts with product 12; Push rod 9 passes core plate 10 and connects scraping wings 14, it is characterized in that having spring groove 15 in the described die cavity 5, and compression spring 16 is installed in the spring groove; Compression spring 16 contacts with gate plate 3, and gate plate connects controlled interval pull rod 17 3 times, and controlled interval pull rod 17 passes compression spring 16 and spring groove 15.During the demoulding, injection machine power drives core 11 and breaks away from die sinking with die cavity 5, still; Because compression spring 16 is installed in the spring groove 15 of die cavity 5, compression spring 16 contacts with gate plate 3, after the mould die sinking; Compression spring 16 has not had clamp force, withstands on gate plate 3 times, and die cavity 5 is separated with gate plate 3; Die cavity 5 moves to the return stroke of compressing spring 16 downwards with core 11, and product 12 and material handle 13 are broken, and this moment, product 12 was still stayed in the die cavity 5; Material handle 13 is stayed in the gate plate 3, will expect that by manual work or manipulator handle takes out.After compression spring 16 bullets were intact, core 11 continued operation die sinking downwards, separated with die cavity 5, and this moment, product 12 was stayed on the core 11, and by scraping wings 14 product 12 was released outside the mould, and the demoulding is accomplished.This programme adopts the reseting elasticity of compression spring, makes the mould twice-die-opening, and product and material handle are broken, and makes product stay on the core to deviate from smoothly, and is simple in structure, handling ease, and easy for installation, cost is economized.
