Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production and processing technology, specifically to a clamping calibration structure for a high-plasticity blow molding die. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and then formed into plastic containers through plastic molds by blow molding, extrusion blow molding, or injection molding. Plastic bottles formed by stretch blow molding are placed in the plastic bottle mold and need to wait for the container to cool and harden before the plastic bottle mold can be opened and the molded bottle can be removed.

[0003] Existing plastic bottle molds typically involve first assembling the mold cap and base to form the mold cavity required for blow molding. Then, external injection molding equipment is used to inject the mold into the mold cavity, completing the injection molding process. However, during blow molding, because injection molding requires applying a certain pressure to the heated liquid plastic to allow it to enter the mold cavity, a misalignment can occur between the mold and the heating head of the injection molding equipment. This leads to a misalignment between the mold cap and the base, resulting in a thick parting line on the blow-molded product and reducing product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping calibration structure for a high-plasticity blow molding die, in order to solve the problem mentioned in the background art that, during the blow molding process, injection molding requires applying a certain pressure to the heated liquid plastic to allow it to enter the mold cavity, which causes the mold and the heating head of the injection molding equipment to shift, resulting in a shift in the position between the mold cap and the base, which leads to a large parting line on the blow-molded product and reduces the quality of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping calibration structure for a high-plasticity blow molding die, comprising a base and a calibration section:

The calibration part is located inside the base. The calibration part has a lower calibration block located on the side of the base. An upper calibration block is slidably provided on the top of the base. A locking block is slidably provided inside the base. The upper calibration block slides to fix the position of the mold cover. The locking block engages with the upper calibration block and slides to fix the position of the upper calibration block.

[0007] By adopting the above technical solution, the sliding upper calibration block and the lower calibration block can cooperate to firmly fix the position of the mold cover on the top of the base, so that the mold cavity formed by the base and the mold cover will not shift during injection molding, thus improving the quality of blow-molded products.

[0010] Preferably, the base also has a groove a formed on the top of the base, and the upper calibration block is embedded in the groove a and slidably connected thereto.

[0011] By adopting the above technical solution, the upper calibration block can be slidably displaced on the top of the base.

[0012] Preferably, the calibration unit further includes a spring a disposed on one side of the upper calibration block, the spring a being located between the spring a and the base.

[0013] By adopting the above technical solution, the upper calibration block can be pushed to slide displacement by the elastic force provided by spring a.

[0014] Preferably, there are two upper calibration blocks, which slide against each other and cooperate with the lower calibration block to form an annular fixing groove.

[0015] By adopting the above technical solution, the mold cover can be firmly fixed by the formed annular fixing groove.

[0016] Preferably, the calibration unit also has a slot at the bottom of the upper calibration block, and the slot and the block are engaged.

[0017] By adopting the above technical solution, the position of the upper calibration block can be fixed by inserting the set card block into the card slot.

[0018] Preferably, the base also has a groove b formed inside the base, the locking block is inserted into the groove b and slidably connected thereto, and a spring b is provided at the bottom of the locking block, the spring b being located between the base and the locking block.

[0019] By adopting the above technical solution, the spring b can be used to push the card block to slide.

[0020] Preferably, the calibration unit also has a push plate disposed on the side of the card block, the push plate extending to the outside of the base.

[0021] By adopting the above technical solution, the pressing of the push plate can drive the locking block to slide inside the base.

This prevents the mold cavity formed by the base 1 and the mold cover 105 from shifting during injection molding, thus improving the quality of the blow-molded product.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a clamping calibration structure for a high-plasticity blow molding die, including a calibration part 2, an upper calibration block 202, and a locking block 205.

[0036] A groove a103 is provided on the top of the base 1. The upper calibration block 202 is inserted into the groove a103 and slidably connected thereto, allowing the upper calibration block 202 to slide and move on the top of the base 1. A spring a204 is provided on one side of the upper calibration block 202, located between the spring a204 and the base 1. The elastic force provided by the spring a204 can push the upper calibration block 202 to slide and move. A groove b104 is provided inside the base 1. A locking block 205 is inserted into the groove b104 and slidably connected thereto. A spring b207 is provided at the bottom of the locking block 205, located between the base 1 and the locking block 205. The locking block can be pushed by the spring b207. 205 Sliding displacement, a push plate 206 is provided on the side of the card block 205, the push plate 206 extends to the outside of the base 1, the card block 205 can be moved to slide displacement inside the base 1 by pressing the push plate 206.

[0037] Working principle: First, the mold cover 105 is aligned with the cavity 101, and connected to the mounting plate 102 via the mounting block 106 to fix one end of the mold cover 105. Then, the two upper calibration blocks 202 slide, overcoming the elastic force of the spring a204, and slide at the top of the base 1. When the two upper calibration blocks 202 come together and abut, the spring b207 pushes the locking block 205 to slide, causing the locking block 205 to engage in the locking groove 203, thus fixing the position of the upper calibration blocks 202. Two upper calibration blocks 202 are provided; they slide together and abut against each other, forming an annular fixing groove with the lower calibration block 201. This annular fixing groove firmly secures the mold cover 105. The lower calibration block 201 and the upper calibration block 202 are fixed with holes on their outward-facing sides for connection with the injection molding equipment. After connection with the injection molding equipment, the heating head of the injection molding equipment can be aligned with the two upper calibration blocks 202 and slide against each other to form an annular fixing groove with the lower calibration block 201. Then, the injection molding equipment injects mold into the mold cavity formed by the cavity 101 and the mold cover 105 to complete the mold injection process. During the blow molding process, the upper calibration block 202 and the lower calibration block 201 cooperate to firmly fix the position of the mold cover 105 on the top of the base 1, so that the mold cavity formed by the base 1 and the mold cover 105 will not shift during injection molding, thus improving the quality of the blow-molded product.
