Abstract
The utility model provides a connector for a lifter and an ejector rod, which is adaptable to the filed of injection molds. The lifter and the ejector rod are connected via a counter balance, one end of the counter balance is provided with a guide sliding groove transversely arranged, one end of the lifter is slidably arranged in the guide sliding groove of the counter balance, and the ejector rod is fixedly connected with the counter balance. The connector for the lifter and the ejector rod utilizes the counter balance to be connected with the lifter and the ejector rod respectively, the counter balance and the ejector rod are kept under the lifter during an ejecting process and a lifter resetting process, and the lifter slides transversely in the guide sliding groove of the counter balance with balance stress, thereby eliminating eccentric moment generated at the connecting position of the lifter and the ejector rod and resolving the problem that buckling position of the lifter is easy to be cracked and damaged.
Description
Technical field
The utility model belongs to miniature precision injection mold field, relates in particular to the connector of a kind of oblique top and push rod.
Background technology
As shown in Figure 1, in miniature precision injection mold field, when product glue bit architecture had little back-off or side recessed, because of spatial constraints, the width of oblique top 91 was generally in 3～10mm scope, for guaranteeing the intensity of oblique top 91, usually oblique top 91 is designed to one-sided hanging platform, ejects through push rod 92 off-centre, but in process of production, because the junction between oblique top 91 and the push rod 92 can produce eccentric moment, makes the button bit of oblique top 91 the bad phenomenon of top rhegma often occur.
The utility model content
The purpose of this utility model is to provide the connector of a kind of oblique top and push rod, is intended to solve the bad problem of the easy top of button bit rhegma of oblique top of the prior art.
The utility model is to realize like this, the connector of a kind of oblique top and push rod, be connected by a balance weight between described oblique top and the push rod, one end of described balance weight offers the guide runner of a horizontally set, one end of described oblique top is slidedly arranged in the guide runner of described balance weight, and described push rod is fixedlyed connected with balance weight.
The other end of described balance weight offers the groove of a horizontally set, and an end of described push rod is fixedly arranged in the groove of described balance weight.
Described balance weight is slidedly arranged in the pilot hole of a rear pattern plate.
The lower surface of described rear pattern plate offers a mounting groove that communicates with described pilot hole.
Be installed with a baffle plate that can prevent described balance weight move left and right in described mounting groove in the described mounting groove.
The lower surface of described rear pattern plate is installed with a guide pad corresponding with described pilot hole, and described push rod is arranged on the described guide pad.
The described push rod other end is located on the thimble panel, and is fixed by an Ejector Retainer Plate that cooperates with described thimble panel.
The oblique top that the utility model provides and the connector of push rod, be connected with push rod with oblique top respectively by balance weight, in process of ejecting and oblique top reseting procedure, balance weight and push rod be in all the time oblique top under, oblique top is laterally slided in the guide runner of balance weight, stress balance has been eliminated the eccentric moment that the junction of oblique top and push rod produces, and has solved the bad problem of the easy top of button bit rhegma of oblique top.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult Fig. 2～shown in Figure 5, the oblique top that the utility model embodiment provides and the connector of push rod, described tiltedly pre-1 with push rod 2 between be connected by a balance weight 3, particularly, one end of described balance weight 3 offers the guide runner 31 of a horizontally set, the other end of described balance weight 3 offers the groove 32 of a horizontally set, and an end of described oblique top 1 is slidedly arranged in the guide runner 31 of described balance weight 3, and an end of described push rod 2 is fixedly arranged in the groove 32 of described balance weight 3.
In addition, described balance weight 3 is slidedly arranged in the pilot hole 41 of a rear pattern plate 4; The lower surface of described rear pattern plate 41 offers a mounting groove 42 that communicates with described pilot hole 41, is installed with a baffle plate 5 that can prevent described balance weight 3 move left and right in mounting groove 42 in the described mounting groove 42; The lower surface of described rear pattern plate 4 also is installed with a guide pad 6 corresponding with described pilot hole 42, and described push rod 2 is arranged on the described guide pad 6; Described push rod 2 other ends are located on the thimble panel 7, and are fixed by an Ejector Retainer Plate 8 that cooperates with described thimble panel 7.
The concrete installation process of the oblique top that the utility model embodiment is provided and the connector of push rod is as follows:
(1) as shown in Figure 3, the rear pattern plate 4 of earlier oblique top 1 being packed into is put into mounting groove 42 with balance weight 3 then, then makes balance weight 3 to oblique top 1 direction translation, and the end of oblique top 1 is slidedly arranged in the guide runner 31 of balance weight 3;
(2) as shown in Figure 4, with push rod 2 pack into thimble panel 7 and guide pad 6, end with push rod 2 snaps in the groove 32 of balance weight 3 with fixing then, then baffle plate 5 is fixed in the fitting recess 42, to stop balance weight 3 move left and right in mounting groove 42, balance weight 3 can only be moved up and down in pilot hole 41;
(3) as shown in Figure 5, guide pad 6 is fixed on the rear pattern plate 4, makes thimble panel 7 retract oblique top 1, promptly finished being connected and installation of oblique top 1 and push rod 2.
The oblique top that the utility model provides and the connector of push rod, be connected with push rod 2 with oblique top 1 respectively by balance weight 3, in process of ejecting and oblique top reseting procedure, balance weight 3 and push rod 2 be in all the time oblique top 1 under, oblique top 1 is laterally slided in the guide runner 31 of balance weight 3, stress balance has been eliminated the eccentric moment of oblique top 1 with the junction generation of push rod 2, has solved the bad problem of the easy top of button bit rhegma of oblique top 1.
