Description

Quick shaping die casting die

Technical Field

The utility model relates to the technical field of die casting dies, in particular to a rapid prototyping die casting die.

Background

In the past gear manufacturing processes, gear casting and demolding operations have relied primarily on conventional manual or semi-automated techniques. Pouring means pouring molten metal or other materials into a prefabricated mold, and taking out after cooling and solidification, thus completing the molding of the gear. And demolding is the process of taking the molded gear out of the mold.

The prior background is as follows:

And (5) manually demolding: conventional manual demolding techniques rely primarily on workers manually striking the mold with tools such as hammers, chisels, etc., to disengage the gears from the mold. This method is still used in some small scale production or specific applications.

The prior art has the following defects:

The production efficiency is low: the demolding speed of the semi-automatic demolding machine is limited to a certain extent whether the demolding machine is used for manual demolding or semi-automatic demolding. Manual operation requires direct intervention by a worker, while semi-automated equipment still has some setup and response time.

The product quality is unstable: in the manual demolding process, the force and angle of each demolding are possibly different due to the influence of human factors, and the inconsistency of the shape, the size and the like of the gears is easy to cause.

The production cost is high: the manual operation requires more labor to participate, and increases the labor cost. At the same time, the wear on the mold is also relatively large, resulting in more frequent mold changes and repairs.

Potential safety hazard: manual demolding operations present certain safety hazards, such as the possibility of workers being scalded by hot molds or being injured when tools are used.

The energy consumption is high: because the residence time of the gears in the mold is longer, more cooling time and energy is required.

Therefore, the technical proposal specially provides a rapid prototyping die casting die to solve the problems.

And the production efficiency is improved:

Due to the high degree of cooperation of the stripping assembly with the drive mechanism, the gear stripping process becomes rapid and automated. Compared with the traditional manual demoulding or slower mechanical demoulding mode, the design greatly shortens the production period and improves the production efficiency.

Optimizing the product quality:

The rapid stripping operation reduces the residence time of the material in the mold, helping to maintain the geometric and dimensional accuracy of the gears. Meanwhile, the automatic demolding process reduces interference of human factors, and consistency and quality of each gear are guaranteed.

The production cost is reduced:

The mechanical rapid demoulding reduces the need of manual operation and reduces the labor intensity and the labor cost. In addition, faster production speeds mean higher throughput and corresponding lower production costs per product.

Basic structure of the mold:

The lower die 1 is positioned at the bottom of the whole die, and the upper die 2 is arranged right above the lower die. In order to ensure stable cooperation of the upper die 2 and the lower die 1, a top table 4 is disposed right above the upper die 2. The top table 4 and the lower die 1 are supported by four guide struts 3, so that the stability and accuracy of the die are ensured.

Designing an upper die:

The upper die 2 is integrally round in shape, and a uniform tooth slot-shaped structure is designed on the inner side wall of the upper die, so that corresponding gear-shaped objects can be formed during die casting.

The center of the upper die 2 is provided with a center through hole 22 for fitting the boss of the center of the lower die 1.

In order to cooperate with the guide posts 3, four guide perforations 21 are uniformly arranged in the side wall of the upper die 2, and the four guide perforations 21 can be sleeved on the four guide posts 3 in a sliding manner.

On both left and right sides of the center perforation 22 of the upper die 2, a liquid injection hole 23 and a vent hole 24 are provided, respectively, for pouring liquid material and discharging gas, respectively.

Design of a demolding assembly:

The demolding assembly 5 is located between the top table 4 and the upper mold 2 and mainly comprises a driving stud 51, a threaded sleeve 52 and a side support arm 53.

The top end of the drive stud 51 is rotationally abutted against the center of the top stage 4 and is abutted with the drive end of the drive mechanism 6. The threaded sleeve 52 is sleeved on the driving stud 51, and the top ends of the four side support arms 53 are respectively arranged in the front, back, left and right directions of the threaded sleeve 52, and the bottom ends of the four side support arms are fixed on the top of the upper die 2.

Configuration of the driving mechanism:

the drive mechanism 6 provides the necessary power for the stripper unit 5 and mainly comprises a drive motor 61, a drive shaft 62, a drive shaft 63 and a drive belt 64.

A drive motor 61 is mounted on top of the top table 4 and is connected to a drive shaft 62. Power is transmitted between the driving shaft 62 and the transmission shaft 63 through a transmission belt 64, so that the driving stud 51 is driven to rotate.

Characteristic design of the lower die:

The center of the top of the lower die 1 is provided with a center boss 7 for cooperation with a center through hole 22 of the upper die 2 to help form a center hole for casting the gear.

In order to reduce vibration of the die during working, the bottom of the lower die 1 is provided with a shock pad 8, so that the vibration can be effectively absorbed, and the service life of the die is prolonged.

The top of the lower die 1 is also provided with a butt joint groove 11 matched with the bottom edge of the upper die 2, so that the accurate butt joint of the upper die and the lower die is ensured.

Working principle of gear pouring and subsequent demoulding

1. Gear pouring:

Preparing a mould: first, perfect abutment of the upper die 2 with the lower die 1 is ensured, wherein the central boss 7 at the top of the lower die 1 is aligned with the perforation 22 in the center of the upper die 2. This provides a closed space for the casting liquid, ensuring that the material does not overflow during the forming process.

And (3) injecting materials: when the mold is ready, the preheated liquid material is fed through the injection port 23 as: and pouring metals such as aluminum, zinc and the like into the mold. Due to the design of the inside of the mould, the liquid material will form the shape of the gear during filling of the mould. At this time, the tooth-shaped structure of the inner side wall of the upper die 2 helps to form the tooth portion of the gear, and the center boss 7 of the top of the lower die 1 helps to form the center hole of the gear.

And (3) discharging gas: in order to prevent the generation of bubbles and to ensure the integrity of the filling of the material during casting, the air and the excess gas inside the mould are discharged through the vent holes 24.

Cooling and solidifying the material: after the injection is completed, the material is cooled and solidified in the mold. The curing process may be relatively rapid due to the good thermal conductivity of the mold material.

2. Demolding working principle:

Starting a driving mechanism: after the gear material is completely cooled and solidified, the demolding operation is started. The drive motor 61 in the drive mechanism 6 is first started. The drive motor 61 transmits power to the drive shaft 63 via the drive shaft 62 and the drive belt 64, and ultimately rotates the drive stud 51.

The threaded sleeve is linked with the side support arm: as the drive stud 51 rotates, the threaded sleeve 52 begins to move upward. Since the top ends of the four side arms 53 are connected to the threaded sleeve 52 and the bottom ends are fixed to the top of the upper die 2, the upper die 2 is driven to move upward so as to be separated from the lower die 1.

And (3) demolding: when the upper die 2 is completely lifted, the gear on the lower die 1 is completely demolded, and the next processing or detection can be performed.

Through the design, the whole pouring and demoulding process realizes high-efficiency, rapid and accurate operation, ensures that the produced gear has high quality and standard shape
