Description

Technical Field

[0001] The utility model relates to the technical field of PCR tube production devices, in particular to a mold for PCR tube production. Background Art

[0002] The molds used to produce PCR tubes for biological experiments are precision tools specifically designed for producing PCR tubes used in the biomedical field. PCR tubes are indispensable consumables in biological experiments and are widely used for gene amplification and detection. Their production relies heavily on high-precision molds, which ensure a high degree of consistency and accuracy during the production process.

[0003] In existing molds for producing PCR tubes used in biological experiments, polypropylene plastic particles are poured sequentially into the cavity of the lower mold. After the material is evenly distributed in the cavity of the lower mold, the upper mold is driven downward by the activation of the driving component. When the pressing is completed, the driving component drives the upper mold to move again, thereby completing the production of the PCR tube.

[0004] However, this device has certain defects. After the device is pressed, the staff needs to take out the PCR tube in the lower template cavity. During the manual removal process, the force and direction may vary depending on the operator, which will affect the consistency of the product and reduce the reliability of the finished product quality.

[0005] Therefore, it is necessary to provide a mold for producing PCR tubes to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a mold for the production of PCR tubes that can achieve automatic demoulding. At the same time, the molded PCR tubes do not need to come into contact with the operator and can be directly collected and processed.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0008] A mold for producing PCR tubes includes: a mold platform, which includes two base plates, which are arranged in opposition to each other through four guide pillars. A fixing component is installed on the lower base plate, and the fixing component includes a side frame installed on one of the base plates. An adjustment component is installed in the side frame. The adjustment component includes two guide frames, and a bidirectional screw is installed in one of the guide frames. One end of the bidirectional screw is connected to a drive motor installed at one end of the side frame. Two groups of guide seats are installed on the bidirectional screw, and lower modules are installed on both groups of guide seats. The two groups of lower modules can be combined to form a molding cavity. A control component is assembled on the upper end of one of the base plates, and the control component includes a hydraulic cylinder. The output end of the hydraulic cylinder is connected to the upper template.

[0009] Preferably, a guide rod is installed in one of the guide frames, and the guide rod is connected through the two sets of guide seats.

[0010] Preferably, the inner cavity of the side frame is provided with a material collecting component, which is specifically a material receiving frame. The material collecting component is installed directly below the lower template composed of two groups of lower modules, and the material collecting component can be pulled out and installed in the side frame.

[0011] Preferably, positioning holes are provided on the two groups of guide seats, and positioning plates are provided on the side ends of the two groups of lower modules. The two groups of lower modules are detachably installed on the two groups of guide seats respectively through the use of positioning plates and positioning bolts.

[0012] Preferably, the two groups of guide seats can move forward and backward within the range of travel set by the two groups of guide frames through the cooperation of bidirectional screws and positioning rods.

[0013] Preferably, fixing plates are welded to both ends of the side frame, and the side frame is detachably mounted on the bottom plate via the fixing plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The utility model can realize the left-right separation of the two lower modules by cooperating with the multiple parts in the fixed component, the module, and the adjusting component. By separating the two lower modules, the demolding process of the PCR tube after processing and forming can be realized. Compared with the traditional manual demolding method, this device can accurately control the left and right lower modules through the bidirectional screw to achieve accurate demolding, thereby reducing product defects and damage caused by improper manual operation;

[0016] (2) The utility model provides a guide rod in one of the guide frames. When the bidirectional screw drives the two sets of guide seats to move in opposite directions, the guide rods are connected through the guide seats. The guide rods ensure that the guide seats can move accurately and symmetrically, thereby ensuring that the left and right sets of lower modules are accurately aligned.

[0017] (3) The present invention provides a material collecting component, which is specifically a material collecting frame. After the left and right groups of lower modules are separated and demolded, the formed PCR tubes can be directly collected into the material collecting component, and finally the material collecting component can be pulled out as a whole. By arranging the material collecting component below the two groups of lower modules, the formed PCR tubes can be collected immediately, which reduces the intervention of operators in the production process, thereby reducing production interruptions and waiting time.
