Description

Silicon-based microneedle mould convenient for demoulding Technical Field The utility model relates to the related field of silicon-based microneedle moulds, in particular to a silicon-based microneedle mould convenient for demoulding. Background The microneedle injection mode has two modes of direct injection and patch, wherein the microneedle on the microneedle patch is generally a soluble microneedle, the microneedle is a micron-scale needle array, and can be widely applied to the biomedical fields of drug delivery, wound healing, biosensing, body fluid sampling and the like as a novel drug delivery system, the microneedle can pass through the stratum corneum in a noninvasive, painless, simple and controllable way to generate systemic or local effect, inconvenience caused by oral administration such as liver first pass effect, gastric acid hydrolysis, drug malabsorption and needle fear is avoided, and a mould is generally adopted to prepare the silicon-based microneedle. The existing device has the defects that when the silicon-based microneedle mould is demoulded, the silicon-based microneedle mould is generally stuck by manual operation or using adhesive to take out the silicon-based microneedle mould from the mould, but the manual demoulding efficiency is low, the silicon-based microneedle is easy to damage, the adhesive is left when the adhesive is used for demoulding, the quality of the silicon-based microneedle is influenced, meanwhile, the workload is increased due to the cleaning of the adhesive, and the production efficiency of the silicon-based microneedle is influenced. Disclosure of utility model The utility model aims to provide a silicon-based microneedle mould convenient for demoulding, which solves the problems in the prior art. The technical scheme is that the silicon-based microneedle mould convenient to demould comprises a base, a silicon-based microneedle upper mould, a silicon-based microneedle lower mould, a ball nut and a demoulding plate, wherein a motor is arranged in the base, a screw rod is arranged at the power shaft end of the motor, the ball nut is arranged on the screw rod in a threaded manner, a supporting rod is arranged on the ball nut, an installation table is arranged at the top end of the supporting rod, the silicon-based microneedle lower mould is arranged on the table surface of the installation table, a support is arranged on the base, a linear motor unit is arranged on the support, an electric telescopic rod C is arranged on the linear motor unit, a demoulding plate is arranged at one end of the electric telescopic rod C, a suction pump is arranged on the demoulding plate, a suction cup is arranged on the bottom surface of the demoulding plate, and the suction pump is connected with the suction cup. According to the technical scheme, the silicon-based material to be processed is placed on the silicon-based microneedle lower die, compression molding is carried out by matching with the silicon-based microneedle upper die, after the silicon-based microneedle is manufactured, the silicon-based microneedle upper die moves upwards, a motor is started to drive a screw rod to rotate, when the screw rod rotates, a ball nut moves linearly on the screw rod, the ball nut drives a supporting rod and a mounting table to move, the mounting table drives the silicon-based microneedle lower die to move below a stripper plate, an electric telescopic rod C is started to push the stripper plate to descend, a sucker on the bottom surface of the stripper plate adsorbs the silicon-based microneedle under the action of a suction pump, then the electric telescopic rod C contracts, the silicon-based microneedle is removed from the silicon-based microneedle lower die, then the stripper plate and the adsorbed silicon-based microneedle are moved to the upper side of a collecting box through a linear motor unit, and the electric telescopic rod B is started to descend a supporting plate, the silicon-based microneedle is placed in the collecting box to collect, so that automatic stripping of the silicon-based microneedle is realized, tedious and low-efficiency of manual stripping is avoided, and viscose residue caused by viscose stripping is avoided, and production efficiency and product quality of the silicon-based microneedle are improved. Preferably, an electric telescopic rod B is installed on the base, a supporting plate is installed at one end of the electric telescopic rod B, a connecting plate is installed on the supporting rod, and the supporting rod is in sliding connection with an opening of the supporting plate. By adopting the technical scheme, after the demolding of the silicon-based microneedle is completed, the motor reversely rotates to drive the silicon-based microneedle lower die to return to the initial position, and the next compression molding operation is prepared.
