Description

Be used for integrative round pin of mould compound die location direction

Technical Field

The utility model relates to a tooling die technical field, concretely relates to be used for integrative round pin of mould compound die location direction.

Background

In the casting and core making process, when a mold is closed, the positioning pin ensures that the mold is not subjected to box staggering, so that the size precision of a sand core is ensured, the length of the positioning section of the positioning pin is too long, the mold cannot be opened after the mold is closed, the general design length is within the range of 25mm, the thickness of the sand core is different, the mold is easy to collide and damage when the mold is closed and exceeds the mold with the depth of 25mm, and at the moment, a guide device needs to be added.

The existing mould is divided into two designs, one is that no guiding device is designed, the other is that a guiding device is designed, when the mould is used, the mould without guiding device is often collided and damaged, and the mould with guiding device is designed, firstly, because the guiding device design occupies more space, the design is all on the core box fixing plate outside the mould body, secondly, the phenomenon of secondary positioning interference with the positioning pin can exist, and the mould closing difficulty is caused, and the practicability of the device is reduced.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to overcome prior art not enough, the present provides a be used for integrative round pin of mould compound die location direction, it divide into two kinds of designs to have solved current mould, one kind is not to design guider, another kind is to design guider, and when the mould uses, the mould that does not design the direction often bumps the damage, and the design has the mould of direction, firstly because guider design more accounts for the spatial position, the design is all on this external core box fixed plate of mould, secondly can have the phenomenon of taking place secondary positioning interference with the locating pin, and lead to the mould assembling difficulty, reduce the problem of device practicality.

(II) technical scheme

The utility model discloses a following technical scheme realizes: the utility model provides a be used for integrative round pin of mould compound die location direction, including last core box body, location uide pin, location section and direction section, it has to go up the embedded location uide pin that has of core box body, the shaping has on the location uide pin the location section, location section below is provided with the direction section, the direction section shaping in on the location uide pin.

Furthermore, a lower core box body is arranged below the upper core box body, an upper core box parting surface is formed on the bottom wall of the upper core box body, and a lower core box parting surface is formed on the top wall of the lower core box body.

By adopting the technical scheme, when the die is closed, whether the die closing is finished or not is determined by observing whether the parting surface of the upper core box is tightly attached to the parting surface of the lower core box or not.

Furthermore, a positioning pin sleeve is arranged in the lower core box body, and the positioning pin sleeve is connected with the lower core box body through a screw.

By adopting the technical scheme, the positioning pin sleeve corresponds to the positioning section in size, so that the depth of die assembly of the device is positioned.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

1. the utility model discloses a through setting up location guide pin, location section and direction section, set up locating pin and guide pin as an organic whole, and the diameter difference of location section and direction section is 0.7-2mm, not only the guide pin, guide pin seat, guide pin sleeve installed on the upper core box fixed plate and lower core box fixed plate are cancelled, and in the use process, the direction location is once put in place, the mold closing and opening are smooth, the manufactured sand core has no error deviation, the mold closing effect of the device is ensured, and the practicability of the device is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-5, in this embodiment, an integrated positioning and guiding pin for mold clamping of a mold includes an upper core box body 1, a positioning guiding pin 2, a positioning section 3 and a guiding section 4, the upper core box body 1 is embedded with the positioning guiding pin 2, the positioning section 3 is formed on the positioning guiding pin 2, the guiding section 4 is disposed below the positioning section 3, the guiding section 4 is formed on the positioning guiding pin 2, the positioning guiding pin 2 integrates the positioning pin and the guiding pin, and the diameter difference between the positioning section 3 and the guiding section 4 is 0.7-2mm, so that not only are the guiding pin, the guiding pin seat and the guiding pin sleeve mounted on the upper core box fixing plate and the lower core box fixing plate cancelled, but also in the using process, the guiding positioning is once in place, the mold clamping and the mold opening are smooth, the core is manufactured without error deviation, the mold clamping effect of the apparatus is ensured, and the practicability of the apparatus is improved.

As shown in fig. 1 to 5, in this embodiment, a lower core box body 7 is disposed below an upper core box body 1, an upper core box parting surface 5 is formed on a bottom wall of the upper core box body 1, a lower core box parting surface 6 is formed on a top wall of the lower core box body 7, and when mold closing is performed, whether mold closing is completed is determined by observing whether the upper core box parting surface 5 and the lower core box parting surface 6 are closely attached.

As shown in fig. 1 to 5, in this embodiment, a positioning pin sleeve 8 is disposed in the lower core box body 7, the positioning pin sleeve 8 is connected to the lower core box body 7 by a screw, and the positioning pin sleeve 8 corresponds to the positioning section 3 in size, so as to position the depth of mold assembly of the apparatus.

The specific implementation process of this embodiment is as follows: when the die is closed, the guide section 4 firstly enters the positioning pin sleeve 8, because the diameter of the positioning pin sleeve 8 is larger than that of the protected guide section 4, the guide section 4 can smoothly pass through the positioning pin sleeve 8, along with the downward movement of the upper core box body 1, the positioning section 3 also starts to enter the pin sleeve, and the fit clearance is obviously reduced until the die closing is completed, when the die closing is completed, the parting surface 5 of the upper core box and the parting surface 6 of the lower core box are completely superposed, and the fit clearance reaches the design size, in the die closing process of the device, because the positioning guide pin 2 integrates the positioning pin and the guide pin, and the diameter difference between the positioning section 3 and the guide section 4 is 0.7-2mm, the guide pin seat and the guide pin sleeve which are arranged on the fixed plate of the upper core box and the fixed plate of the lower core box are cancelled, and in the use process, the guide positioning is once in place, the die closing and die opening are smooth, the manufactured sand core has no error deviation, the mold closing effect of the device is ensured, and the practicability of the device is improved.

The above examples are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention.
