Abstract
The invention discloses a kind of tubing molding die.It includes two halves to the cavity plate of opening structure and the punch-pin that can be placed in cavity plate, there is adaptable with tube surfaces and spaced Multi-segment circular groove in the cavity of cavity plate, punch-pin includes inner tube and is placed in the outer die body of multi-disc of inner tube outer surface, the outer surface that the outer die body of multi-disc is placed in inner tube forms complete body of punch, there is the outline being adapted with cavity plate inner chamber, punch-pin to form tubing die cavity after being placed in cavity plate for the outer surface of body of punch.After above-mentioned structure, tubing can be made after being placed in cavity plate, its smart structural design, as long as extracting inner tube out in the demoulding causes each outer die body to come off naturally, realize the purpose that is easily stripped and its cleverly structure design greatlys save die cost, in addition, its structure form it is reasonable, the demoulding will not destroy product in itself, substantially increase the quality of product.
Description
Technical field
The present invention relates to a kind of production mould, specifically a kind of tubing molding die.
Background technology
It is well known that polypropylene pipe in pipeline is corrosive liquid mainly for delivery of concentrated nitric acid etc., it is existing
Polypropylene pipe forms in manufacturing process generally by molding tool molding, and existing molding die can only make surface light
Sliding tubing, for demoulding difficulty or mould using existing mould often be present with tubing of the concaveconvex structure compared with big ripple
The variety of problems such as cost height, and cause the quality of product to be not easy to ensure.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of be convenient in demoulding, the tubing that good product quality and manufacturing cost are low
Molding die.
In order to solve the above-mentioned technical problem, tubing molding die of the invention, including two halves are to the cavity plate and energy of opening structure
The punch-pin being enough placed in cavity plate, the cavity of cavity plate is interior with adaptable with tube surfaces and spaced Multi-segment circular groove, convex
Mould includes inner tube and is placed in the outer die body of multi-disc of inner tube outer surface, and the outer surface that the outer die body of multi-disc is placed in inner tube has been formed
There is the outline being adapted with cavity plate inner chamber, punch-pin to be formed after being placed in cavity plate for whole body of punch, the outer surface of body of punch
Tubing die cavity.
Corresponding screwed hole is provided with the inwall of said inner tube and outer die body, said inner tube and outer die body pass through fastening
Part is fixedly mounted.
The front and rear sides of the punch-pin are provided with sealing baffle, and the punch-pin is close by sealing baffle after being placed in cavity plate
Envelope installation.
The cavity plate of opening structure is fixedly mounted the two halves by fastener.
After above-mentioned structure, because punch-pin is made up of die body outside inner tube and multi-disc, in the outer die body of multi-disc is placed in
The outer surface of pipe forms complete body of punch, and tubing can be made after being placed in cavity plate, its smart structural design, de-
As long as extracting inner tube out during mould each outer die body is come off naturally, realize the purpose that is easily stripped and its cleverly structure
Design greatlys save die cost, in addition, its structure is formed rationally, the demoulding will not destroy product in itself, substantially increase production
The quality of product.
Brief description of the drawings
Fig. 1 is the structural representation of half block cavity plate in the present invention；
Fig. 2 is the overall structure diagram of convex mould of the present invention；
Fig. 3 is the end structure illustration of convex mould of the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, the tubing molding die of the present invention is described in further detail.
As illustrated, the tubing molding die of the present invention, including two halves to the cavity plate 1 of opening structure and can be placed in cavity plate
The cavity plate 1 of opening structure is fixedly mounted by fastener for interior punch-pin 2, two halves, is had and tube surfaces phase in the cavity of cavity plate 1
Adaptation and spaced Multi-segment circular groove 3, punch-pin 2 includes inner tube 4 and is placed in the outer die body 5 of multi-disc of inner tube outer surface, interior
Corresponding screwed hole is provided with the inwall of pipe 4 and outer die body, inner tube and outer die body are fixedly mounted by fastener, outside multi-disc
The outer surface that die body 5 is placed in inner tube 4 forms complete body of punch, and the outer surface of body of punch has what is be adapted with cavity plate inner chamber
Outline, punch-pin 2 form tubing die cavity after being placed in cavity plate 1.
Further, the front and rear sides of described punch-pin 2 are provided with sealing baffle, and punch-pin 2 passes through after being placed in cavity plate 1
Sealing baffle sealing installation, so that tubing die cavity can form a complete seal cavity, realizes the mesh of compression molding
's.
