Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a lateral core-pulling mold. Background Art

[0002] Molds are essential tools in injection molding. Injection molding involves injecting hot melt plastic material at high speed into a sealed mold cavity with the desired shape. Once the plastic material cools and solidifies, the mold is opened and the solidified plastic product is ejected to create the finished product. Injection molding is widely used in plastic product applications due to its low cost, short cycle times, simple molding process, and ease of forming complex plastic products.

[0003] When injection molding a product with holes, grooves or bosses on the side, when opening the mold, these holes or concave-convex directions are inconsistent with the demolding direction, causing interference with the core and preventing normal demolding. At this time, a lateral parting mechanism is required to achieve this. The traditional slider-type parting mechanism cannot effectively position these parts, which easily causes interference between the insert and the injection mold, resulting in damage to the injection mold.

[0004] For example, a side core-pulling mold disclosed in announcement number CN211054321U realizes the core-pulling operation of the automobile ball head product by arranging the lower mold core-pulling, elastic elements and ejector pins on the lower mold assembly. By arranging the inner fixed slider and cooperating with the ejector pin, the effective positioning of the insert is achieved. By arranging the outer fixing part, the inner fixed slider is fixed, thereby ensuring the positioning effect of the insert.

[0005] However, for products with undercuts and holes on all sides, the conventional practice is to use inclined guide columns instead of sliding blocks, which makes the mold frame too large and the customer's machine cannot produce it.

[0006] For this reason, we urgently need to provide a kind of lateral core-pulling die. Utility Model Content

[0007] The purpose of the utility model is to provide a lateral core-pulling mold to solve the problem in the background technology mentioned above that for products with undercuts and holes on all sides, the conventional practice is to use inclined guide columns instead of sliding blocks, resulting in a mold frame that is too large and the customer's machine cannot produce.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lateral core-pulling mold, comprising a slide seat, wherein there are two slide seats, a slider is slidably connected to the outside of the slide seat, pressure blocks are installed on the left and right sides of the slider, a shovel is slidably connected to the inside of the pressure block, a limiting clamp is installed at the bottom of the pressure block, a two-color mold is installed in the middle of the slider, a single-color hard rubber is installed on the left side of the two-color mold, and two-color soft rubber is installed on the right side of the two-color mold.

[0009] Preferably, an inclined slot is provided on the outside of the slide seat, and the slider can slide up and down along the slot. When the mold is opened, a downward pulling force is applied to the slider by pressing down on both sides of the shovel, so that the slider moves backward to separate the slider from the two-color mold.

[0010] Preferably, a wear-resistant block is fixedly installed on the bottom of the slider to protect the slider from wear and damage during long-term movement.

[0011] Preferably, a connecting groove adapted to the shovel is provided inside the pressing block, and the shovel is slidably connected in the connecting groove.

[0012] Preferably, there are two pressing blocks and shovels, which are symmetrically distributed on the left and right sides of the slider. By pressing down on both sides of the shovel, a downward pulling force is applied to the slider, so that the slider moves backward to achieve separation of the slider and the two-color mold.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the side core-pulling mold needs to be opened, the two sides of the shovel are pressed down to apply a downward pulling force to the slider. After the slider is forced, it moves backward along the slide seat to separate the slider from the two-color mold. The structure is simple and safe, ensuring the distance of the side core pulling. The structure is compact and occupies a small space. It can process products with undercuts and round holes on the side, solving the problem raised in the background technology that for products with undercuts and holes on all sides, the conventional practice is to use inclined guide columns instead of sliders, resulting in a mold frame that is too large and the customer's machine cannot be produced.

[0015] 2. The side core-pulling mold is provided with a wear-resistant block to protect the slider from long-term movement from wear and damage, thereby increasing the service life of the slider. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A side core-pulling mold includes a slide 1, through which the product can be side core-pulled. An inclined slide groove is provided on the outside of the slide 1, and the slider 2 can slide up and down along the slide groove. When the mold is opened, the slider 2 is pressed down on both sides by the shovel 4 to apply a downward pulling force to the slider 2, so that the slider 2 moves backward to achieve the separation of the slider 2 and the two-color mold 6. There are two slides 1, and the slider 2 is slidably connected to the outside of the slide 1. A wear-resistant block 9 is fixedly installed on the bottom of the slider 2. The wear-resistant block 9 protects the slider 2 from long-term movement from wear and damage. Pressing blocks 3 are installed on the left and right sides of the slider 2. The slider 2 is accurately positioned and guided by the pressing block 3. A connecting groove compatible with the shovel 4 is provided inside the pressing block 3. The shovel 4 is slidably connected in the connecting groove, and the shovel 4 is slidably connected inside the pressing block 3 to drive the slide 1 to move and guide. The shovel 4 drives the slider 2 to pull the core to ensure the distance of the lateral core pulling, so that the reset structure design is simple. There are two pressing blocks 3 and shovels 4, and they are symmetrically distributed on the left and right sides of the slider 2. By pressing down on both sides of the shovel 4, a downward pulling force is applied to the slider 2, so that the slider 2 moves backward to achieve the separation of the slider 2 and the two-color mold 6. A limit clamp 5 is installed at the bottom of the pressing block 3, and the movement distance of the slider 2 is limited by the limit clamp 5. A two-color mold 6 is installed in the middle of the slider 2, and a single-color hard glue 7 is installed on the left side of the two-color mold 6, and a two-color soft glue 8 is installed on the right side of the two-color mold 6.

[0024] During use, when the mold needs to be opened, the shovel machine 4 is used to press down on both sides to apply a downward pulling force to the slider 2. After the slider 2 is subjected to the force, it moves backward along the slide seat 1 to separate the slider 2 from the two-color mold 6. The structure is simple and safe, ensuring the distance of the lateral core pulling, the structure is compact, and it occupies a small space.
