AI Technical Summary

Technical Problem

The existing die-casting mold slider is integrated, which is easy to deform and collapse under high speed, high pressure and high temperature conditions, resulting in high risk of repair welding and failure to meet customer demand sizes. The new slider is costly and has a long cycle, resulting in idle die-casting machine and waste of labor hours.

Method used

A split die-casting module slider is designed. The head and bottom of the slider can be separated, and the rapid disassembly and connection is achieved through the coordination of the limiting slot and the positioning connector. The dovetail plus pin composite fixing is used to simplify the replacement process.

Benefits of technology

It realizes rapid separation and replacement of the slider inlet head and bottom, reduces the mold repair cycle and labor cost, ensures rapid replacement of molds and stable dimensions, and improves production capacity.

Description

Technical Field

[0001] The utility model relates to the technical field of a die-casting mold slider insert, in particular to a split die-casting mold slider insert. Background Art

[0002] The slider inserts of the die-casting mold currently used are integrated. Due to the high speed, high pressure and high temperature characteristics of the die-casting production process, it is very easy to cause deformation, chipping and erosion of the slider insert head. The risk of abnormal workpieces will be high when the chipped slider insert is repaired by welding, and the slider deformation cannot meet the size required by customers. If the cost of making a new slider is high and the new manufacturing cycle is long, the die-casting machine will be idle, labor hours will be wasted and product delivery will be affected. Utility Model Content

[0003] In order to solve the above technical problems, the utility model designs a split type die casting mold slider insert.

[0004] The utility model adopts the following technical solutions:

[0005] A split-type die-casting mold slider insert comprises a slider insert base, a connecting part and a slider insert head. The slider insert base is fixedly connected to the connecting part, a limiting slot is provided on the connecting part, a limiting protrusion is correspondingly provided on the slider insert head, the limiting protrusion is fitted and embedded in the limiting slot, and a positioning connector is installed between the limiting protrusion and the connecting part. Through the cooperation of the positioning connector, the limiting protrusion and the limiting slot, the slider insert head and the connecting part are detachably connected.

[0006] Preferably, the limiting slot is a dovetail slot, and the limiting protrusion is a corresponding dovetail-shaped protrusion.

[0007] Preferably, the positioning connector is a positioning pin, and pin holes are correspondingly provided on the connecting portion and the limiting protrusion, and the positioning pin is inserted into the pin hole for positioning.

[0008] Preferably, the connecting portion is integrally formed with the slider base.

[0009] The beneficial effects of the utility model are as follows: (1) the utility model is suitable for slider inserts with complex structures and no space for arranging screws, ensuring that the mold can quickly replace the upper mold for production, with stable dimensions and improved production capacity; (2) the slider insert base is a standardized structure and can be reused, avoiding dimensional abnormalities caused by repeated processing of the slider insert base, saving materials and money; (3) the slider insert is fixed by a dovetail plus pin composite fixation, which makes replacing the insert head structure simple, saves time and effort, shortens the mold repair cycle, saves time, and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is an exploded diagram of the utility model;

[0012] In the figure: 1. Slider into the sub-base, 2. Connecting part, 3. Slider into the sub-head, 4. Positioning pin, 5. Limiting slot, 6. Limiting protrusion, 7. Pin hole. DETAILED DESCRIPTION

[0013] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0014] Example: Figure 1 and Figure 2 As shown, a split-type die-casting mold slider insert includes a slider insert base 1, a connecting part 2 and a slider insert head 3. The slider insert base is fixedly connected with the connecting part, and a limiting slot is provided on the connecting part. A limiting protrusion 6 is correspondingly provided on the slider insert head. The limiting protrusion is fitted into the limiting slot 5, and a positioning connector is installed between the limiting protrusion and the connecting part. Through the cooperation of the positioning connector, the limiting protrusion and the limiting slot, the slider insert head and the connecting part are detachably connected.

[0015] The limiting slot is a dovetail slot, and the limiting protrusion is a corresponding dovetail-shaped protrusion.

[0016] The positioning connector is a positioning pin 4, and the connecting portion and the limiting protrusion are provided with corresponding pin holes 7, and the positioning pin is inserted into the pin hole for positioning. The connecting portion and the slider base are integrally formed.

[0017] The utility model changes the slider insert from being integrated into a structure with a detachable head and a detachable bottom. When the slider insert head is deformed or broken, a new head can be directly replaced, thereby realizing quick and convenient detachment of the slider insert head and the bottom. At the same time, in order to ensure that the slider insert head and the bottom are easy to detach and do not affect the die-casting production of the slider insert, a dovetail pin is added to the connection between the slider insert head and the bottom for fixing. The dovetail can fix the slider insert in the front, back, left, and right directions, and the pin can fix the slider insert in the up and down directions.

[0018] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
