Abstract
The present invention relates to a precisely positioning device in the process of the coating and the injection molding of a connector terminal. An inserting block of a detachable drawer type flake structure, which is connected with an embedding block of an injection molding core, is added to the embedding block of the injection molding core; the connector terminal to be processed is fixed through a groove of the inserting block and a positioning pin, which can greatly reduce a reject rate in the process of the injection molding and enhance economic benefit.
Description
Technical field
The invention belongs to the injection mo(u)lding field.Relate in particular to the accurate positioning device of bonder terminal in injection mold.
Background technology
In the coated injection moulding process of bonder terminal, only be provided with the terminal fixing hole on the core rod of traditional moulds, by directly terminal being inserted into fixed terminal in the fixing hole, without any other location measure.Because the injection moulding meeting produces great impulse force in the product injection moulding process, only adopt traditional terminal fixing hole localization method can make terminal that moving backward taken place, influence the qualification rate of product.Consequent dimension overproof, if surpass 1 ± 0.25, will make this product with its to loose contact between the accessory or contact and open circuit.According to statistics, because the percent defective that this dimension overproof produces is about 4% ~ 5%.So high disqualification rate had both increased production cost and inspection cost, had influenced the benefit of company, because return goods, reprocess, qualified products can't be provided on schedule, thereby influence CSAT again.
Summary of the invention
The present invention overcomes deficiency of the prior art, the accurate positioning device of a kind of bonder terminal in coating and injection moulding process is provided, utilize this kind device processing connector, can reduce even avoid in injection moulding process impact to terminal, make terminal can at will not be moved, thereby reduce percent defective greatly.
The present invention is achieved through the following technical solutions:
Go up insert (3) that increase links to each other with abaculus (2) at core rod (1), these insert (3) can slide in abaculus; Insert (3) be designed to detachable flake structure; End in these insert (3) is provided with the alignment pin of projection; One end of band alignment pin can stretch out abaculus (2); These insert (3) are provided with groove simultaneously, and the quantity of groove is consistent with the quantity of terminal to be processed, and width is slightly larger than the width of terminal to be processed.
Utilize the method for the accurate positioning device processing connector of this bonder terminal in coating and injection moulding process: band alignment pin one end of will insert (3) is released, terminal to be processed is fixed on the groove of insert (3), alignment pin is matched with aperture on the terminal; To insert (3) push back in the core rod; Core rod (1) is put into counterdie, then matched moulds, injection moulding.
Accurate positioning device provided by the invention compared with prior art, its beneficial effect is, can success avoid terminal arbitrarily moving in mould, make this product thus the disqualification rate that causes of dimension overproof drop to from original 4% ~ 5% and approach 0, both reduced production cost, increase economic efficiency again, relative customer satisfaction also improves greatly.
Description of drawings
Fig. 1 is the front view of the accurate positioning device of bonder terminal in coating and injection moulding process;
Fig. 2 is the vertical view of the accurate positioning device of bonder terminal in coating and injection moulding process;
Fig. 3 is the cutaway view at Fig. 2 A-A position.
The specific embodiment
As shown in Figure 1, 2, on original connector injection moulding monoblock type core rod 1, increase link to each other with abaculus 2 detachably insert 3, these 3 drawer-type structures of inserting for activity, promptly this is inserted and 3 can slide in abaculus 2.This length of 3 of inserting is greater than the width of core rod 1, so be exposed at abaculus 2 outer parts and can control its in the inside and outside slip of abaculus 2 by promoting it; Be provided with the alignment pin of projection at this end of 3 inserted, and the relevant position of terminal also is provided with the circular hole that is complementary with it; This is inserted and 3 is provided with groove simultaneously, and the quantity of groove is consistent with the quantity of terminal to be processed, and its width is slightly larger than the width of terminal to be processed.
Utilize the method for the accurate positioning device processing connector of this bonder terminal in coating and injection moulding process: insert 3 band alignment pin one end of drawer type is released, terminal to be processed is fixed on 3 the groove inserted, alignment pin is matched with aperture on the terminal; Drawer type inserted 3 push back in the core rod 2; Core rod 1 is put into counterdie, then matched moulds, injection moulding.
Claims (4)
1. the accurate positioning device of a bonder terminal in coating and injection moulding process, comprise core rod (1), abaculus (2), its feature also comprises insert (3) that are slidingly connected in the abaculus (2), one end of described inserting (3) is provided with positioner, and the extended abaculus of an end (2) of this positioner, described inserting (3) is provided with groove, and the quantity of described groove is consistent with the quantity of terminal to be processed, and width is slightly larger than the width of terminal to be processed.
2. the accurate positioning device of a kind of bonder terminal according to claim 1 in coating and injection moulding process is characterized in that described positioner is an alignment pin.
