Abstract
The invention discloses an injection mold for threaded products. The injection mold comprises a front mold and a rear mold; in addition, the injection mold also comprises a screw rod and a gear. The injection mold for threaded products is additionally provided with the screw rod and the gear, therefore, when in work, the screw rod and the gear are meshed together, the gear and the threaded product in the cavity of the mold are meshed together; when the mold is opened, the front mold pulls the screw rod to separate from the rear mold, the screw rod drives the gear to rotate, the gear rotates to drive the threaded product out of the cavity of the mold. Therefore, the threaded product can be taken out of the cavity of the injection mold by the self-structure without an additional motor, thus not only the cost is saved, but also the forming cycle of the products is shortened.
Description
Technical field
The present invention relates to a kind of screw product injection mold, particularly relate to and a kind ofly the injection mold goods are taken out structure carried out improved screw product injection mold.
Background technology
The material that melts that will be heated when injection mold is meant work is injected die cavity by high pressure, behind cooling curing, obtains a kind of mould of molded article.This kind mould can be applied in the batch process of complex-shaped parts, is one of important processing mold.The process of injection molding of injection mold is broadly divided into following 6 stages and is followed successively by: matched moulds, injection, pressurize, cooling, die sinking, goods take out, and carry out repeatedly by above-mentioned technology, just can continuously produce end article.And the screw product injection mold just is meant the injection mold that can produce screw product.The screw product injection mold needs that after screw product is shaped it is taken out promptly corresponding above-mentioned goods from injection mold and takes out the stage.As Fig. 1, traditional method is to eject screw product 40 by motor 30 rotations.But, the mode that adopts motor 30 rotations to eject screw product 40 need be equipped with motor 30 in addition, simultaneously, also needs to set up a step of utilizing motor 30 rotations to eject screw product 40, has increased the molding cycle of product.
In sum, problem demanding prompt solution is, need take out structure to traditional injection mold goods and improve, and makes it can not need to be equipped with motor 30 in addition but just can be with screw product 40 taking-ups by the structure of injection mold self.
Summary of the invention
Technical problem to be solved by this invention is, a kind of screw product injection mold is provided, it does not need to be equipped with motor in addition but just screw product can be taken out by the structure of injection mold self, so promptly provides cost savings, and has shortened the molding cycle of product yet.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of screw product injection mold, this injection mold comprises: front mould, back mould, in addition, this injection mold also comprises: screw rod and gear, wherein, mould inside forms die cavity after described front mould and the back die combination, and this die cavity is used to the screw product that is shaped; Described screw rod and described gear are interlocked, and the screw product in described gear and the die cavity is interlocked; During die sinking, described front mould spurs described screw rod and leaves described back mould, and described screw rod drives described gear and rotates, and rotating band went out the screw product in the die cavity when described gear rotated.
Advantage of the present invention is, the present invention has set up screw rod and gear in the screw product injection mold, described screw rod and described gear are interlocked during work, screw product in described gear and the die cavity is interlocked, described front mould spurs described screw rod and leaves described back mould during die sinking, described screw rod drives described gear and rotates, and rotating band went out the screw product in the die cavity when described gear rotated.Therefore, do not need to be equipped with in addition again motor, just the screw product in the injection mold die cavity can be taken out, so promptly provide cost savings, shortened the molding cycle of product yet by the structure of injection mold self.
Description of drawings
Fig. 1 is the original screw product injection mold overall structure schematic diagram when taking out formed product;
Fig. 2 is the overall structure schematic diagram of screw product injection mold of the present invention.
The specific embodiment
For further disclosing technical scheme of the present invention, be described with reference to the accompanying drawings embodiments of the present invention now.
Fig. 1 is the original screw product injection mold overall structure schematic diagram when taking out formed product, as shown in the figure, utilizes conventional method when the screw product injection mold takes out formed product, is to eject screw product 40 by motor 30 rotations.
Fig. 2 is the overall structure schematic diagram of screw product injection mold of the present invention, as shown in the figure, wherein, comprise: front mould 10, back mould 20, in addition, this injection mold also comprises: screw rod 51 and gear 52, wherein, described front mould 10 and back mould 20 combination back mould insides form die cavity 60, and this die cavity 60 is used to the screw product that is shaped; Described screw rod 51 and described gear 52 are interlocked, and the screw product in described gear 52 and the die cavity 60 is interlocked; During die sinking, the described screw rod 51 of described front mould 10 pullings leaves described back mould 20, and described screw rod 51 drives described gear 52 and rotates, and rotating band went out the screw product in the die cavity 60 when described gear 52 rotated.
Action situation when working below in conjunction with description of drawings the present invention:
During work, mould inside forms die cavity 60 behind front mould 10 and back mould 20 matched moulds, the material that melts is injected die cavity 60 by high pressure with being heated, behind cooling curing, carry out the die sinking operation, during die sinking, the described screw rod 51 of described front mould 10 pullings leaves described back mould 20, and described screw rod 51 drives described gear 52 and rotates, and rotating band went out the screw product in the die cavity 60 when described gear 52 rotated.
By above analysis as can be known, the present invention just can take out screw product 40 by the cooperation between the injection mold self structure, does not need to be equipped with in addition motor 30 again.
More than, the basic ideas and basic principles of the present invention have been set forth by description of listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
