Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a pump-type pipe bending mold. Background Technology

[0002] In the industrial manufacturing sector, pump bends are widely used, and their production quality and efficiency depend heavily on the performance of the molds. Traditional pump bend molds have many shortcomings in design and use.

[0003] Traditional molds often employ a top-bottom parting surface structure with an unreasonable slider design. On one hand, the varying lengths of the slider pins on the flat-drawing side lead to high spare parts costs and inconvenient maintenance and replacement. On the other hand, the stepped design of the angled flat-drawing side demands extremely high precision in the machining of the mold core and slider inserts, increasing machining difficulty and scrap rate, and significantly raising manufacturing costs. Furthermore, this structure results in the parting line being located directly above the product, making it very noticeable after assembly, severely impacting the product's aesthetic appearance and reducing its market competitiveness.

[0004] With industry development, the market has placed higher demands on the appearance and cost control of pump bends. The shortcomings of traditional molds make them difficult to meet modern production needs. Therefore, there is an urgent need for a new type of pump bend mold that can improve product aesthetics and reduce mold manufacturing costs by optimizing parting surface design, slider structure, and mold core arrangement. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by placing the parting surface on the left and right sides, so that the parting line is located on the side after product assembly. Compared with the traditional structure where the parting line is on top of the product, this significantly improves the overall appearance quality of the product, meets the market's higher requirements for aesthetics, and enhances the customer's user experience.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution that can both improve the aesthetics of the product and reduce the cost of mold manufacturing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pump-type pipe bending mold includes a mold frame, an upper mold, a lower mold, a mold core, and a slider assembly. The upper mold is a three-plate mold structure, and parting surfaces are provided on the left and right sides of the mold. The slider assembly includes a symmetrically arranged left slider seat and a right slider seat. The right slider seat has a dovetail groove structure, and a matching slider insert is provided within the dovetail groove structure. The slider insert has its movement direction defined by a pressure block. A slider pin is installed on the slider insert. The mold core and the slider insert are arranged in a straight line, and the slider pins have a uniform length.

[0009] Preferably, the left and right slider seats are driven by inclined guide pillars to slide outward synchronously when the parting surface opens, and the dovetail groove structure of the right slider seat drives the slider insert to complete the inclined demolding action.

[0010] Preferably, the contact surface between the mold core and the slider insert is a plane, eliminating the stepped arrangement, and the slider insert is installed on the right slider seat.

[0011] Preferably, the mold frame size is smaller than that of a traditional upper and lower parting surface structure.

[0012] Preferably, the parting line of the parting surface is located on the left and right sides after the product is assembled, and the parting line smoothly transitions with the product surface.

[0013] Preferably, the sliding trajectory of the dovetail groove structure is consistent with the demolding direction of the product's inner hole.

[0014] Preferably, the pressure block is fixed to the right slider seat by bolts.

[0015] Preferably, the mating surface between the slider insert and the dovetail groove structure is provided with a wear-resistant coating, and the coating material is titanium nitride or tungsten carbide.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The pump-type pipe bending mold provided in this application, by setting the parting surface on the left and right sides, makes the parting line located on the side after product assembly. Compared with the traditional structure where the parting line is on the top of the product, it significantly improves the overall appearance quality of the product, meets the market's higher requirements for aesthetics, and enhances the customer's user experience.

[0018] Reduce mold manufacturing costs: Adopt a dovetail groove design to achieve uniform slider pin length and reduce spare parts costs; replace the stepped arrangement of mold core and slider inserts with a straight arrangement, which reduces the machining accuracy requirements, simplifies the machining process, and reduces the scrap rate; optimize the slider and parting surface design, reduce the mold base size, and further reduce the cost of mold manufacturing materials.

[0019] Improved production efficiency and stability: The movement direction of the slider insert is precisely limited by the pressure block, ensuring accurate and stable demolding action. Combined with the ejection mechanism, this guarantees smooth product molding and demolding, improving production efficiency. Simultaneously, the wear-resistant coating on the mating surfaces of the slider insert and the dovetail groove structure enhances the wear resistance and service life of mold components, reducing the frequency of maintenance and replacement due to component wear, and ensuring production stability and continuity.

Example

[0031] Please see Figure 1-5 A pump-type pipe bending mold includes a mold base 1, an upper mold 2, a lower mold 3, a mold core 11, an ejection mechanism, and a slider assembly. The upper mold 2 is a three-plate mold structure, with parting surfaces on the left and right sides. The slider assembly includes a symmetrically arranged left slider seat 6 and a right slider seat 7. The right slider seat 7 has a dovetail groove structure 8, and a matching slider insert 9 is provided in the dovetail groove structure 8. The slider insert 9 has its movement direction limited by a pressure block 10. A slider pin 12 is installed on the slider insert 9. The mold core 11 and the slider insert 9 are arranged in a straight line, and the slider pin 12 has a uniform length.

[0032] The pump-type pipe bending mold of this application is mainly composed of mold frame 1, upper mold 2, lower mold 3, mold core 11, ejection mechanism and slider assembly, etc. The following is a detailed description of its structure and working principle.

[0033] I. Detailed Structure and Connection Methods of Each Component

[0034] Mold overall structure installation: The mold frame 1 serves as the basic support structure, and the upper mold 2 and lower mold 3 are installed and fixed. The mold core 11 is installed between the upper mold 2 and the lower mold 3 to form a cavity for molding pump-type bent pipes. The left side slider seat 6 and the right side slider seat 7 are symmetrically installed on the left and right sides of the mold, and are connected to other parts of the mold through the inclined guide post 13, and can move under the drive of the inclined guide post 13.

[0035] Slider assembly installation: A dovetail groove structure 8 is provided on the right-side slider seat 7, and the matching slider insert 9 is installed inside the dovetail groove structure 8. A pressure block 10 is used to fix it to the right-side slider seat 7 with bolts, limiting the movement direction of the slider insert 9 so that it can only move diagonally downwards in the direction of pin ejection. Slider pins 12 of uniform length are installed on the slider insert 9. Simultaneously, a wear-resistant coating is applied to the mating surface of the slider insert 9 and the dovetail groove structure 8. The coating material is titanium nitride or tungsten carbide to improve wear resistance.

[0036] II. Working Principle

[0037] Mold Closure: The upper mold 2 and lower mold 3 are closed, and the mold core 11 forms a complete cavity, into which the material for manufacturing pump-type bends is injected. At this time, the left slider seat 6 and the right slider seat 7 are in their initial positions under the positioning action of the inclined guide post 13. The slider insert 9 and the mold core 11 together form a complete molding space, and the slider pin 12 is also located in the corresponding position to form the inner hole and other parts of the product.

[0038] Mold Opening: After injection molding, the mold opens, with the upper mold 2 and lower mold 3 opening along the parting surfaces on the left and right sides. Simultaneously, the left slider seat 6 and the right slider seat 7 slide outward in sync under the drive of the inclined guide post 13. The dovetail groove structure 8 of the right slider seat 7 drives the slider insert 9 to move. Since the movement direction of the slider insert 9 is limited by the pressure block 10, the slider insert 9 moves obliquely downward in the direction of the insert pin demolding, causing the slider pin 12 to disengage from the inner hole of the product, completing the oblique demolding action.

[0039] Through the coordinated operation of the above components, the pump-type pipe bending mold of this utility model achieves efficient and high-quality molding of the product, improves the product's aesthetics, and reduces the mold manufacturing cost.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
