Without the mould structure of thimble vestige on a kind of injecting products
Technical field
The utility model relates to mould, more specifically, relates to the mould structure without thimble vestige on a kind of injecting products.
Background technology
A lot of mould of plastics all uses thimble to be ejected when the demoulding at present, therefore can produce the vestige of thimble when the demoulding, especially the injection moulding of triple valve, such shortcoming is, affects attractive in appearance, and the pore volume ejected is easy to wear, mold repair difficulty improves, the long processing time of mould.
Utility model content
In order to solve above technical problem, first the utility model provides the mould structure without thimble vestige on a kind of injecting products, comprise charging aperture, runner, front core rod, side form core, rear core rod and thimble, described runner connects charging aperture, the both sides of charging aperture are provided with side form core, the upper end of charging aperture is provided with front core rod, the lower end of charging aperture is provided with rear core rod, described thimble withstands charging aperture, make charging aperture can do the motion of the demoulding, described side form core can move to both sides, described rear core rod is fixed, described front core rod moves in company with charging aperture, described front core rod, side form core, rear core rod and runner form the structure of injecting products.
Preferably, 2 charging apertures are provided with.
Described injecting products is 3 logical plastic valves.
Described thimble is provided with 3, withstands runner respectively, and 2 charging apertures.
The utility model has the advantage of:
1. change the traditional handicraft adopting thimble directly to be ejected by plastic product, thimble is revised as and withstands gating location, make thimble pass through to eject charging aperture, plastic product is taken out of.
2. the plastic product of the utility model acquisition is without thimble vestige, and the requirement of multi-mould is lower.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 is thimble, and 2 is rear core rod, and 3 is side form core, and 4 is front core rod, and 5 is charging aperture, and 6 is runner.
Detailed description of the invention
The utility model is further described below in conjunction with the drawings and specific embodiments.Unless stated otherwise, the utility model adopts reagent, equipment and method are conventional commercial reagent, equipment and the conventional method used of the art.
