Abstract
本实用新型公开一种注塑产品上无顶针痕迹的模具结构，包括进料口、流道、前模芯、侧模芯、后模芯及顶针，所述的流道连接进料口，进料口的两侧设有侧模芯，进料口的上端设有前模芯，进料口的下端设有后模芯，所述的顶针顶住进料口，使得进料口可以做脱模的运动，所述的侧模芯可以向两侧移动，所述的后模芯固定，所述的前模芯随同进料口移动，所述的前模芯、侧模芯、后模芯和流道形成注塑产品的结构。本实用新型利用流道形成的塑料，用顶针将塑料产品带出，因此获得的塑料产品无顶针痕迹。
The utility model discloses a mold structure without traces of thimbles on injection molding products, comprising a feed port, a flow channel, a front core, a side core, a rear core and a thimble, the flow channel is connected to the feed port, and the feed There are side mold cores on both sides of the inlet, a front mold core on the upper end of the feed inlet, and a rear mold core on the lower end of the inlet. The thimble supports the inlet, so that the inlet can be demoulded The movement of the side mold core can move to both sides, the rear mold core is fixed, the front mold core moves with the feed inlet, the front mold core, side mold core, rear mold core and Runners form the structure of injection molded products. The utility model uses the plastic formed by the flow channel to take out the plastic product with a thimble, so the obtained plastic product has no trace of the thimble.
Description
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.
Embodiment 1
Without the mould structure of thimble vestige on a kind of 3 logical plastic valves, comprise 2 charging apertures, runner, front core rod, side form core, rear core rod and thimble, 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, thimble withstands charging aperture, make charging aperture can do the motion of the demoulding, side form core can move to both sides, 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, thimble is 3, withstand runner respectively, and 2 charging apertures.
Claims (4)
1. on an injecting products without the mould structure of thimble vestige, it is characterized in that, 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.
