Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to a mold that facilitates the shearing of the material head. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically manufactured using rubber or plastic injection molding. Injection molding can also be divided into injection molding and die casting.

[0003] In the injection molding industry, after a product is molded, there will be residual adhesive around the product. This residual adhesive needs to be removed manually, which is time-consuming and labor-intensive, increasing the product cost. Utility Model Content

[0004] This invention provides a mold for easy shearing of the material head, aiming to solve the problem in the prior art where adhesive residue remains around the product after molding, requiring manual trimming and removal, which is time-consuming, labor-intensive, and increases product costs.

[0005] This utility model is implemented as follows: a mold for easy shearing of material heads includes an upper mold, a feeding pipe, a lower mold, and a mold groove. The upper surface of the lower mold has a device groove, which is located outside the mold groove. A blade is slidably connected to the inner wall of the device groove. The outer wall of the lower mold has a movable groove, and an elastic plate is movably connected inside the movable groove. The elastic plate and the blade are fixedly connected. A limit block is provided on the upper outer wall of the elastic plate, and a fixing block matching the limit block is fixedly connected to the outer wall of the upper mold. The fixing blocks are symmetrically distributed along the vertical center line of the upper mold. The movable groove and the elastic plate are symmetrically distributed along the vertical center line of the lower mold.

[0006] Preferably, the upper and lower outer walls of the limiting block are respectively provided with guide grooves, and the guide grooves are respectively on the upper and lower outer walls of the fixing block.

[0007] Preferably, the inclination angle of the guide groove on the lower outer wall of the limiting block is smaller than that of the guide groove on the upper outer wall of the limiting block.

[0008] Preferably, the fixing block and the limiting block are made of stainless steel.

[0009] Preferably, the outer wall of the fixing block is fixedly connected to a mounting plate, and the mounting plate is bolted to the upper mold.

[0010] Preferably, the limiting block and the elastic plate are connected by bolts.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] After the upper mold, feeding pipe, lower mold, and mold groove work together, the product is formed in the mold groove. The colloid is compressed and remains between the upper and lower molds. The remaining colloid is formed together with the product. When the upper mold rises, the limiting block will obstruct the fixing block. The fixing block drives the limiting block to move upward, which in turn drives the elastic plate to move the blade upward. The upward movement of the blade cuts the colloid around the product, which facilitates the separation of the remaining colloid from the product. No manual trimming or removal is required, which improves the production efficiency of the equipment. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a mold for easily shearing material heads, such as... Figure 1-4As shown, the mold includes an upper mold 1, a feeding pipe 2, a lower mold 3, and a mold groove 4. The upper surface of the lower mold 3 is provided with a device groove 5, and the device groove 5 is located outside the mold groove 4. A blade plate 6 is slidably connected to the inner wall of the device groove 5, and a movable groove 7 is provided on the outer wall of the lower mold 3. An elastic plate 8 is movably connected inside the movable groove 7, and the elastic plate 8 is fixedly connected to the blade plate 6. A limit block 9 is provided on the upper outer wall of the elastic plate 8, and a fixing block 10 matching the limit block 9 is fixedly connected to the outer wall of the upper mold 1. The fixing blocks 10 are symmetrically distributed along the vertical center line of the upper mold 1, and the movable groove 7 and the elastic plate 8 are symmetrically distributed along the vertical center line of the lower mold 3.

[0021] It should be noted that, in existing technologies, after product molding, residual adhesive remains around the product's perimeter. This residual adhesive requires manual trimming and removal, which is time-consuming, labor-intensive, and increases product costs. Therefore, to address this issue, this solution utilizes the upper mold 1, feeding pipe 2, lower mold 3, and mold groove 4. The product is molded within the mold groove 4, and the adhesive, under pressure, remains between the upper mold 1 and lower mold 3, forming along with the product. When the upper mold 1 rises, the limiting block 9 obstructs the fixing block 10, causing the fixing block 10 to move the limiting block 9 upwards. This, in turn, causes the elastic plate 8 to move the cutting plate 6 upwards. The upward movement of the cutting plate 6 cuts the adhesive around the product, facilitating the separation of the residual adhesive from the product without manual trimming, thus improving equipment production efficiency.

[0022] In a further preferred embodiment of this utility model, such as Figure 4 As shown, guide grooves are respectively provided on the upper and lower outer walls of the limiting block 9, and the guide grooves are respectively on the upper and lower outer walls of the fixing block 10.

[0023] In this embodiment, the guide groove facilitates the exchange of positions between the fixing block 10 and the limiting block 9.

[0024] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the inclination angle of the guide groove on the lower outer wall of the limiting block 9 is smaller than that of the guide groove on the upper outer wall of the limiting block 9.

[0025] In this embodiment, the small inclination angle of the guide groove on the lower outer wall of the limiting block 9 increases the friction when the fixing block 10 rises and disengages from the limiting block 9, thereby ensuring that the blade 6 follows the limiting block 9 as it rises to cut the residual colloid.

[0026] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the fixing block 10 and the limiting block 9 are made of stainless steel.

[0027] In this embodiment, the fixing block 10 and the limiting block 9, made of stainless steel, have good weather resistance, which improves the service life of the fixing block 10 and the limiting block 9.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the outer wall of the fixing block 10 is fixedly connected to the mounting plate 11, and the mounting plate 11 is bolted to the upper mold 1.

[0029] In this embodiment, the mounting plate 11 and the upper mold 1 are connected by bolts, which facilitates the replacement of the fixing block 10 by personnel.

[0030] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the limiting block 9 and the elastic plate 8 are connected by bolts.

[0031] In this embodiment, the limiting block 9 is connected to the elastic plate 8 by bolts, which facilitates the replacement of worn limiting blocks 9 by personnel.
