Abstract
Water route docking structure on a kind of chopsticks injection mold of the present invention is related to daily life meal preparation field, including fixed mold, pin end and female connector；Water route is equipped in the shaft core of fixed mold；The pin end is installed on the entrance in water route after axially being docked with female connector；The shaft orientation flowing channel being equipped in the pin end and female connector；The interface of the pin end and female connector uses the structure of convex cone match.The water route docking structure easy leak when solving the problems, such as in original structure using sealing ring, prevents leak using the mating surface of convex cone, cleverly improves docking structure, even if infiltration is also controlled in accessible range, increase integrally-built safety.
Description
Technical field
The present invention relates to daily life tableware preparation fields, are docked more particularly to the water route on a kind of chopsticks injection mold
Structure.
Background technology
In throwaway chopsticks injection mold, cooling system is its core, the life to the service life, injection-molded item of mold
Producing efficiency and quality all has important influence.When water route is mainly manifested in formed product to the qualitative effects of moulded products, water
Road is for controlling mold temperature, and the variation of mold temperature is strong to the shrinking percentage deformation of product, dimensional stability, machinery
Degree, stress cracking and surface quality etc. have an impact.In existing technical solution, water route on mold cores mouthful in template
Sealing ring is commonly used at the docking of water route to dock, but passes through long-term practice situation and finds, is easy to using sealing ring at docking
The case where generating leak, since sealing ring will produce deformation in the case of pressure, temperature variation, has led to sealing ring
The bad problem of sealing effect, a large amount of water leakage situations will influence the molding of product.
Invention content
The invention mainly solves the technical problem of providing the water route docking structure on a kind of chopsticks injection mold, designs
Rationally, simple in structure, solve the problems, such as easy leak at the water route docking of mold cores.
In order to solve the above technical problems, one aspect of the present invention is to provide on a kind of chopsticks injection mold
Water route docking structure, including fixed mold, pin end and female connector；Water route is equipped in the shaft core of fixed mold；The public access
Head is installed on the entrance in water route after axially being docked with female connector；The shaft orientation flowing channel being equipped in the pin end and female connector；Institute
The interface for stating pin end and female connector uses the structure of convex cone match.
Preferably, the interface of pin end is equipped with the axial raised conical surface, be then equipped on the interface of female connector with
The indent conical surface that the protrusion conical surface mutually agrees with.
Preferably, the fixed mold forming part and mounting portion；The water route is opened up from the end face of mounting portion, water route edge
It the axial direction of the fixed mold and extends to the front end of forming part.
Preferably, the settlement of installation pin end, female connector, the aperture of the settlement are equipped in the inlet in water route
More than the aperture in water route.
The beneficial effects of the invention are as follows：A kind of water route docking structure on chopsticks injection mold is provided, solves original knot
When using sealing ring in structure the problem of easy leak, leak is prevented using the mating surface of convex cone, cleverly improves docking structure,
Even if infiltration is also controlled in accessible range, integrally-built safety is increased.
Description of the drawings
Fig. 1 is the structural schematic diagram of the water route docking structure on a kind of chopsticks injection mold of the present invention；
Fig. 2 is the structure sectional view of fixed mold；
Fig. 3 is the partial enlarged view of water route docking structure；
The label of each component is as follows in attached drawing：1, fixed mold；2, pin end；3, female connector；4, water route.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Attached drawing 1 to 3 is please referred to, the embodiment of the present invention includes：
A kind of water route docking structure on chopsticks injection mold, including fixed mold 1, pin end 2 and female connector 3.Cover half
Core 1 includes forming part and mounting portion, and mounting portion is stair-stepping revolving body, and the shaft core of fixed mold 1 is equipped with water route 4, water
Road 4 is opened up from the rear end face of fixed mold 1, axial direction of the water route 4 along fixed mold 1 and the front end extension to fixed mold.Water
The design on road 4 is to help the molding of throwaway chopsticks, makes one by the water route opened up in the axial direction of fixed mold 1
Secondary property chopsticks accelerate to be cooled and shaped outward from inner cavity, while the water route in whole set of die in template being assisted to cool down so that chopsticks at
The better ideal of type, while also improving processing efficiency.It is equipped with installation pin end 2, female connector in the inlet in water route 4
3 settlement, the aperture of settlement are more than the aperture in water route.Pin end 2 is installed on waterway inlet after axially being docked with female connector 3
Settlement in, the shaft orientation flowing channel being equipped in pin end 2 and female connector 3, the runner on pin end 2, female connector 3 is docked and connected
It is docked again with water route 4 afterwards.Pin end 2 uses the structure of convex cone match with the interface of female connector 3：The interface of pin end 2
It is equipped with the axial raised conical surface, the indent conical surface mutually agreed with the protrusion conical surface is then equipped on the interface of female connector 3.It is original
Structure in be the placement sealing ring at docking, whens monofilament arrangement works easy leak, the cooling water spilt is handled not in time
It will influence formed product.And prevent leak, convex surface downward using the mating surface of convex cone in the technical program, it is concave upright,
Docking structure is cleverly improved, the pressing force of mating surface is increased, even if infiltration is also controlled in accessible range, is increased
Integrally-built safety is added.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
