Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an injection mold for injection products with an inclination angle. Background Art

[0002] Injection molding, also known as injection mold molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, and a variety of color and pattern varieties. It is suitable for mass production and molding processing fields of products with complex shapes. During the injection process, the raw material melted by heat is injected into the molding cavity by high pressure of an injection molding machine, and the product is obtained after cooling and solidification. It is widely used in the production of spare parts in various industries. For example, the outer shells of various pump bodies are widely injection molded using injection molds.

[0003] Some injection products, such as the outer shell of a pump body, have a complex structure and an inclination angle or an inclined protrusion on the product itself. After injection molding, it is difficult for the mold to demold. In addition, due to the inclination angle of the injected product itself, the internal structure of the injection mold also has a matching inclination angle during processing, which also makes the processing of such injection molds difficult.

[0004] In view of this, we propose an injection mold for injection products with an inclination angle. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art that when injecting products with an inclination angle, it is difficult for the mold to demold, and it also makes the processing of such injection molds difficult, and to propose an injection mold for injection products with an inclination angle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An injection mold for injection products with an inclination angle includes a lower mold and an upper mold. A slide bar is slidably connected inside the upper mold, and the slide bar is designed to be inclined; the slide bar is detachably connected to the upper mold; the slide bar penetrates through the bottom and top of the upper mold.

[0008] Preferably, a fixing block is detachably connected to the upper mold; a sliding block is provided at the top of the slide bar, and the sliding block slides inside the fixing block, and the sliding block extends out of the top of the fixing block.

[0009] Preferably, it further includes a mold opening bar; a clamping groove is provided at the top of the sliding block, and a clamping block is provided at the bottom of the mold opening bar; the clamping block is slidably clamped with the clamping groove.

[0010] Preferably, a threaded hole is provided at one end of the mold opening bar away from the clamping block.

[0011] Preferably, there are multiple sets of the lifter rods, and multiple sets of the lifter rods are all slidably connected in the upper mold.

[0012] Preferably, there are two sets of the lifter rods.

[0013] Compared with the prior art, the utility model provides an injection mold for an injection-molded product with an inclination angle, and has the following beneficial effects:

[0014] 1. For the injection mold for an injection-molded product with an inclination angle, through the design of the lifter rods, during the demolding process, the lifter rods can first be separated from the inclination angle in contact, and then when the upper mold is separated from the lower mold, it can move horizontally and directly demold, reducing the demolding difficulty.

[0015] 2. For the injection mold for an injection-molded product with an inclination angle, through the detachable connection between the lifter rods and the upper mold, the mold can be processed separately during the processing and assembled later. Through this split design, the processing difficulty is also greatly reduced. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment:

[0026] Referring to Figures 1 - 6 , an injection mold for an injection-molded product with an inclination angle includes a lower mold 1 and an upper mold 101. The lower mold 1 is fixed on a workbench or other objects. During injection molding, the upper mold 101 is driven to move downward and engage with the lower mold 1 for injection molding. A lifter rod 3 is slidably connected inside the upper mold 101. The lifter rod 3 is designed to be inclined, that is, the lifter rod 3 slides obliquely inside the upper mold 101, and the inclined direction is parallel to the direction of the inclination angle 201. The lifter rod 3 is detachably connected to the upper mold 101.

[0027] The lifter rod 3 penetrates through the bottom and top of the upper mold 101. As Figure 4 , the bottom of the lifter rod 3 is in contact with the inclination angle 201 on the product body 2. The bottom of the lifter rod 3 is hollow, and its outer shape is similar to the outer shape of the inclination angle 201. During injection molding, the inclination angle 201 on the product body 2 is completed through the bottom of the lifter rod 3.

[0028] The product body 2 is the product to be injection-molded, such as the housing of a pump body or other products with an inclination angle.

[0029] After injection molding is completed, first pull the lifter rod 3 upward. The lifter rod 3 moves obliquely upward and disengages from the inclination angle 201 on the product body 2. Then, the upper mold 101 can be driven to move to complete demolding.

[0030] Through the design of the lifter rod 3, during the demolding process, the lifter rod 3 can be made to disengage from the inclination angle 201 first. Then, when the upper mold 101 disengages from the lower mold 1, it can move horizontally and directly demold, reducing the demolding difficulty.

[0031] Meanwhile, by the detachable connection between the ejector rod 3 and the upper mold 101, the mold can be processed separately during the processing. A corresponding mounting hole is machined on the upper mold 101 with a milling cutter, and the ejector rod 3 is also processed separately. After both are processed, they are assembled. Through this split design, the processing difficulty is also greatly reduced.

[0032] As Figure 3 , Figures 4 - 6 , a fixing block 302 is detachably connected to the upper mold 101, and the fixing block 302 is fixed to the upper mold 101 by bolts 303.

[0033] A sliding block 301 is provided at the top of the ejector rod 3. The ejector rod 3 and the sliding block 301 are integrally formed. The sliding block 301 slides within the fixing block 302, and the sliding block 301 extends out of the top of the fixing block 302.

[0034] During installation, first, the part of the ejector rod 3 passing through the sliding block 301 is sleeved on the fixing block 302, and then the fixing block 302 is fixed to the upper mold 101 by bolts 303, improving the installation stability.

[0035] Here, it also needs to be explained that since the ejector rod 3 is inclined, the corresponding mounting hole machined on the upper mold 101 is also inclined. For the convenience of processing, a relatively large groove is milled at the top of the mounting hole, and then the lower inclined mounting hole is processed through the groove.

[0036] Then during installation, in order to prevent gaps from existing around the area of the sliding block 301 at the top of the ejector rod 3, the fixing block 302 is designed to fill this gap, preventing the ejector rod 3 from shaking and improving the stability.

[0037] The mounting hole on the fixing block 302 is also inclined, with the same inclination angle as the mounting hole on the upper mold 101.

[0038] The ejector rod 3 is designed in multiple groups, preferably two groups. Multiple groups of ejector rods 3 are all slidably connected within the upper mold 101.

[0039] Through the multiple-group design, it can meet the requirement that there are multiple inclination angles 201 on the same product body 2, or simultaneously inject multiple product bodies 2 as needed.

[0040] An injection mold for injecting products with inclination angles disclosed in this embodiment further includes an ejector rod 4; a clamping groove 402 is provided at the top of the sliding block 301, and a clamping block 401 is provided at the bottom of the ejector rod 4; the clamping block 401 is slidably clamped with the clamping groove 402, that is to say, the clamping block 401 is clamped and slides within the clamping groove 402, and the ejector rod 4 can only slide within the clamping groove 402 through the clamping block 401.

[0041] The mold opening rod 4 is vertically designed.

[0042] The mold opening rod 4 is connected to a linearly movable power source, such as a cylinder or other power equipment, through the top to drive the mold opening rod 4 to move up and down. The driving direction is the same as the moving direction of the upper mold 101, so there is no need for inclined driving movement, which improves the convenience of driving the slide bar 3 to move.

[0043] During the process of the mold opening rod 4 driving the slide bar 3 to move, the latch 401 slides in the slot 402 to avoid interference.

[0044] A threaded hole 5 is provided at one end of the mold opening rod 4 away from the latch 401. The mold opening rod 4 is connected to a power source or other equipment through the threaded hole 5.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
