Abstract
The utility model relates to the field of injection moulds, and discloses a split injection mould core, which comprises a mould core body (1), wherein the mould core body (1) is sleeved in a mould core seat (2), the mould core body (1) is provided with a bulge (11), the mould core seat (2) is provided with a step groove (23) matched with the bulge (11), and the mould core seat (2) is fixed on a base through bolts. The mould core disclosed by the utility model is convenient to maintain, at the same time the utilization ratio of product components is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to the injection mold field, relates in particular to a kind of bottle of embryo injection core.
Background technology
In the production process of plastic products, need utilize mold injection molding, in the processing process owing to carry out simultaneously in enormous quantities; Just need a large amount of core rods; Therefore the cost of manufacture of core rod becomes original speech that very big influence power is arranged for whole production, and the cost of core rod descends and will bring the decline of pulling production cost, for enterprise increases benefit; The making of current general core rod all is a monoblock type, can and reduce cost in the independent making of some non-vitals.
Someone also once improved the material of core rod, and in application on April 3 nineteen ninety-five, on March 5th, 1997 was announced as Minnesota Mining and Manufacturing Company; Application number is 95192310.2; Notification number is the patent of CN1144502, and name is called core material and injection moulding process, a kind of core material that is used for injection moulding; The copolymer that contains polyvinyl alcohol (PVA) and PEO (PEO), and the core rod that forms by said core material.This improvement on core material is more to help core material better to play a role, and product quality is higher, but the also increase thereupon of its cost can not be done better optimize to product on economy.
Summary of the invention
The utility model is to shortcoming such as easy-maintaining, cost height not in the prior art, the split type injection core that provides a kind of separate type to save cost, be easy to safeguard.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Split type injection core comprises the core rod body, and described core rod body is socketed in the core rod seat, and the core rod body is provided with convexity, and the core rod seat is provided with and the protruding step trough that cooperates, and the core rod seat is through being bolted on the pedestal.
Be designed to split type injection core by traditional injection core, core rod body and core rod seat are wanted to separate, become two independently parts, cooperatively interact in use again.
As preferably, the core rod seat comprises flange and upright tube, and flange is the square-section, and upright tube is connected on the flange, and upright tube becomes step trough away from a side direction sunken inside of flange.
As preferably, protruding outside dimension is less than the internal diameter of step trough, and protruding and step trough are through being welded to connect and forming weld seam.
As preferably, the head of core rod body is a circular arc.
Side direction sunken inside away from flange in the upright tube becomes step trough; Being provided with of step trough is beneficial to the core rod body, and to be installed into the core rod seat inner; Also install the space is provided for the cooperation of core rod body and core rod seat; The core rod body is provided with the convexity that matches with step trough, and the slit between ladder and the convexity is as weld seam.
Step trough links to each other with the mode of convexity through welding, and its reliability is higher.
According to the technical scheme of the utility model, the use of core rod will be more prone to maintenance, and the product component utilization rate increases, and production cost is lower.

The toponym that each number designation referred in the above accompanying drawing is following:
1-core rod body, 2-core rod seat, 3-weld seam, 11-convexity, 21-flange, the upright tube of 22-, 23-step trough.
The specific embodiment
Below in conjunction with the accompanying drawing 1 to 4 and the specific embodiment the utility model is described in further detail:
Embodiment 1
According to accompanying drawing 1 to 4, split type injection core, described core rod body 1 is socketed in the core rod seat 2, and core rod body 1 is provided with convexity 11, and core rod seat 2 is provided with the step trough 23 that cooperates with protruding 11, and core rod seat 2 is through being bolted on the pedestal.Core rod seat 2 comprises flange 21 and upright tube 22, and flange 21 is the square-section, and upright tube 22 is connected on the flange 21, and the upright tube 22 side direction sunken insides away from flange 21 become step trough 23.Protruding 11 outside dimension is less than the internal diameter of step trough 23, and convexity 11 and step trough 23 are through being welded to connect and forming weld seam 3.The head of core rod body 1 is a circular arc, is convenient to core rod body 1 and the 2 assembling sockets of core rod seat.
Core rod is made up of core rod body 1 and core rod seat 2, and core rod body 1 is the main building block of core rod, and core rod seat 2 is mainly as the installation of core rod and tighten up parts; Core rod seat 2 has flange 21 and upright tube 22 two parts, and core rod body 1 is positioned in the upright tube 22, and matches with core rod seat 2; Between core rod body 1 and core rod seat 2, the slit is arranged; Upright tube 22 caves inward into and forms a step trough 23, and upright tube 22 extends outward a convexity 11 that matches with step trough 23, forms weld seam 3 between convexity 11 and the step trough 23; Core rod body 1 is weldingly connected at weld seam 3 places with core rod seat 2; Core rod body 1 is made by standard as the critical piece of core rod, and core rod seat 2 can adopt weaker a little material to form, thereby saves a part of production cost.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
