Description

Technical Field

[0001] This utility model relates to the field of preforming machine technology, and in particular to a precision preforming machine with a pressure mechanism. Background Technology

[0002] In the field of materials processing, preforming technology has a crucial impact on the final product quality and production efficiency. Traditional preforming equipment often faces numerous problems during material extrusion molding. For example, it is difficult to precisely control the discharge speed and pressure during material extrusion, which can easily lead to uneven discharge and significantly reduce the dimensional accuracy and quality stability of the molded products. Utility Model Content

[0003] The purpose of this invention is to provide a precision preforming machine with a pressure mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution, which includes a base, a material cylinder at the top of the base, a die head at one end of the material cylinder, a pressure extrusion assembly at the end of the material cylinder away from the die head, a hopper at one side of the top of the material cylinder, an mounting plate at one side of the material cylinder, the mounting plate being located on the side of the die head, and a cutting assembly on the mounting plate.

[0005] As a preferred embodiment, the pressure extrusion assembly includes a telescopic cylinder disposed at the tail end of the barrel. After the telescopic rod of the telescopic cylinder passes through the barrel, a U-shaped support is disposed at the top of the telescopic rod. A pusher slide is disposed on the U-shaped support. A second motor is disposed on the back of the pusher slide. A transmission rod is disposed on the transmission end of the second motor. The transmission rod passes through the pusher slide, and a spiral pusher pattern is disposed on the wall on the other side of the pusher slide.

[0006] As a preferred embodiment, a sealed bearing is provided inside the pusher slider, and the transmission rod is disposed inside the sealed bearing.

[0007] As a preferred embodiment, a sealing ring is provided on the outer wall of the pusher slider.

[0008] As a preferred embodiment, the cutting assembly includes a first motor mounted on a mounting plate, and a cutting blade is mounted on the drive end of the first motor, the cutting blade being located in front of the die head.

[0009] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0010] This invention uses a telescopic cylinder in a pressure extrusion assembly to push a pusher slider to compress the material, which can push the material out of the die head in a relatively stable and uniform manner. This makes the extruded material more regular in shape and size, laying a good foundation for subsequent precision preforming, effectively improving the precision and quality of the molded product, and reducing molding defects caused by uneven material output.

[0011] When the material output speed is slow, the second motor in the pressure extrusion assembly can play a role. The second motor drives the transmission rod to rotate, and the spiral pushing pattern on the transmission rod further pushes the material, thereby pressurizing the material and effectively increasing the output speed. This design allows the device to flexibly adjust the output speed according to actual production needs, avoiding the impact on production progress due to slow output, and ensuring the continuity and efficiency of the production process.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figures 1-4As shown, the present invention proposes a precision preforming machine with a pressurizing mechanism. The basic structure of the entire device is composed of a base 1. A material cylinder 10 is firmly placed on the top of the base 1. One end of the material cylinder 10 is equipped with a die head 11 for material forming and extrusion, and the other end is equipped with a pressurized extrusion assembly 3. At the same time, a hopper 12 is installed on one side of the top of the material cylinder 10 to facilitate material feeding. An installation plate 13 is provided on one side of the material cylinder 10, and the installation plate 13 is located on the side of the die head 11 to support the cutting assembly 2.

[0019] For the pressure extrusion assembly 3, its core component is a telescopic cylinder 30 located at the tail of the barrel 10. The telescopic rod of the telescopic cylinder 30 can pass through the barrel 10. A U-shaped support is fixed at the top of the telescopic rod. A pusher slide 32 is installed on the U-shaped support. A second motor 35 is installed on the back of the pusher slide 32. The transmission end of the second motor 35 is connected to a transmission rod 36. The transmission rod 36 passes through the pusher slide 32, and a spiral pusher pattern 37 is provided on the wall on the other side of the pusher slide 32. In order to ensure that the transmission rod 36 rotates stably in the pusher slide 32 and does not affect the material sealing, a sealing bearing 34 is installed in the pusher slide 32, so that the transmission rod 36 is placed in the sealing bearing 34. At the same time, a sealing ring 33 is provided on the outer wall of the pusher slide 32 to enhance its sealing performance and prevent material leakage.

[0020] The cutting assembly 2 mainly consists of a first motor 20 mounted on the mounting plate 13 and a cutting blade 21 connected to its transmission end. The cutting blade 21 is precisely positioned in front of the die head 11. When the material is extruded from the die head 11, the first motor 20 drives the cutting blade 21 to rotate, which can cut and segment the extruded material in a timely manner, thereby completing the material extrusion and cutting forming process of the entire device.

[0021] In use, the material is first heated and melted to a suitable viscosity, and then introduced into the hopper 12. Simultaneously, the telescopic cylinder 30 and the cutting assembly 2 are activated. The telescopic cylinder 30 pushes the telescopic rod to extend, and the material is squeezed by the pusher slider 32, causing it to be extruded from the die head 11. During the extrusion process, the first motor 20 drives the cutting blade 21 to rotate at high speed, cutting the extruded material into segments. If the material extrusion speed is slow, the second motor 35 can be turned on. While the pusher slider 32 squeezes the material, the second motor 35 drives the transmission rod 36 to rotate, and the material is further pushed by the spiral pusher pattern 37 to achieve pressurized extrusion, thereby effectively increasing the discharge speed. When the screw approaches one end of the barrel 10, the telescopic cylinder 30 will stop, and the material will be extruded by the spiral pusher pattern 37 alone.

[0022] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
